Abstract:

O processo de Bolonha obrigou a uma aposta na qualidade do ensino superior, para garantir o nível de exigência entre os cursos e também pela exigência de maior competitividade. A nível nacional, a Agência para a Avaliação e Acreditação seguiu as recomendações europeias e definiu referenciais para um sistema interno de qualidade. A Universidade de Évora, com o objetivo de se adaptar a estes referenciais e para melhorar o seu Programa da Qualidade, encetou uma revisão ao sistema interno da qualidade. Este trabalho procura dar alguns contributos na melhoria dos processos mais relevantes para a garantia da qualidade. Como resultados apresenta-se um conjunto de processos modelados e são testados vários critérios de gestão, que permitem automatizar os pontos de decisão nos processos. No futuro há que proceder à melhoria contínua dos processos e aprofundar a gestão por processos, para além de continuar a implementar o Programa da Qualidade, tornando-o cada vez mais integrado com a governação da Universidade; ABSTRACT: The Bologna process led to a commitment to quality in higher education, to ensure the level of requirements among the programs and also by the need of greater competitiveness. In our country, the Agency for Assessment and Accreditation followed European recommendations and set a benchmark for internal quality system. The University of Évora, in order to adapt to these benchmarks and to improve its Quality Program, undertook a review of its quality internal system. This work attempts to give some contributions for processes improvement more relevant to quality assurance. As a result, it is presented a set of modelled processes and tested several management criteria, which allow to automate gateways in the process. In the future it must proceed the continuous processes improvement and extend processes management, as well as continuing to implement the quality program, making it more integrated with the governance of the University.

Abstract:

L'objectiu d'aquest treball és identificar els determinants que influeixen en la implementació i desenvolupament de sistemes d'assegurament de la qualitat en les institucions d'educació superior (IES) i comparar diferents regions amb canvis similars. En un escenari així, és necessari comprendre els processos que han portat a l'actual política educativa així com al canvi de visió que han experimentat al llarg del temps en la comunitat europea (CE). En aquest ordre d'idees, l'educació superior en particular i l'educació en general han passat a ocupar el centre de les preocupacions a la gran majoria del món. El treball aquí presentat es divideix en sis capítols. El primer explora els antecedents i les dinàmiques iniciades en les IES europees en termes dels processos de canvi i reforma que van enfrontar abans, durant i després d'un dels principals acords intergovernamentals anomenat; procés de Bologna. Així mateix es plantegen els objectius i les preguntes de recerca que guien l'estructura d'aquest treball. El capítol 2 comença amb una anàlisi de la literatura sobre els diferents conceptes i visions de qualitat, particularment en l'àmbit de l'educació superior. En els capítols 3 i 4 s'estableix una estratègia de recerca empírica en dues fases; un estudi de casos múltiple i un estudi de casos en profunditat, respectivament. En el tercer s'analitzen les definicions sobre tres dels principals conceptes utilitzats en aquest estudi: qualitat (Westerheijden 2010), assegurament de la qualitat (Vlǎsceanu et al. 2007) i sistema intern d'assegurament de la qualitat [SIAQ] (Cheng 2003). Així mateix s'explora la forma en què els SIAQ s'implementen i desenvolupen. El quart capítol comença amb una primera aproximació cap a un marc conceptual que permet veure el tema de la qualitat com un domini de polítiques a partir de la proposta de *Perellon (2007). Aquest capítol conclou preguntant sobre l'efectivitat dels SIAQ i intenta comparar processos d'implementació paral·lels entre universitats en termes de possibles convergències o divergències. En tots dos apartats es descriu el procés i els criteris utilitzats per a la selecció dels casos. En el capítol 5 es presenta una discussió dels resultats de la recerca empírica i s'intenta contestar a les preguntes de recerca 2, 3 i 4. Finalment, en el capítol 6 es resumeix i exposen alguns punts per a futures línies de recerca. The aim of this work is to identify the main factors which influence in the implementation and development of Quality Assurance Systems in higher education institutions (HEIs), and compare different regions with similar changes. In such scenary, it becomes a necessary task try to understand the processes that have led to the current education policy as well as the changes in the vision which the European Community (EC) has had on higher education over time. In this vein, higher education and education in general have moved from a marginal location towards the center of the concerns in almost all over the world. So far, Higher Education Institutions (HEIs) do not work in a vacuum, but they are an important part of today's knowledge society. Through out a multiple case studies and two indepth case studies (Qualitative Methodology), was analyzed the way in which different internal quality assurance systems (IQAS) have been implemented and developed in six universities, [three from the Euroepan Union (EU) and three from Latin America (LA)]. From the observation of these cases in the field of quality assurance in higher education, we propose the use of some categories that provide an overview of the quality assurance as a policy domain within which policies are formulated. Derived from literature review were identified three big lines of work related with quality assurance issues in higher education; historical analysis; theoretical approaches, and political change. The latter has served as guideline to guide our work within the quality assurance in HEIs, particularly in reference to recurrent practices to evaluate the quality of some of the HEIs activities and the structures associated with these practices (Vlǎsceanu et al. 2007). In this proposal we follow a comparative approach to the political process, the outputs and outcomes of policies that facilitate discovering empirical relationships between variables, particularly in the field of public policies. Far to find answers, the results take us to consider some questions about possible patterns or guidelines associated to processes like the Bologna's for instance and compared with the Latin-American situation. This assignment speaks of quality assurance as a tool for the integration and improvement of higher education, also considers the quality assurance within the policy domain, as well as its different forms of implementation resulting from a national policy or transnational and whose impact is reflected in the actions taken by the HEI’s. Even though is not a prescriptive framework, the EFQM excellence model perspective, allows to identifying the basic elements which compose the structure of QA system which is based on the application of the principles of Total Quality Management (TQM) towards educational institutions. Whatever the origin of these new activities, no doubt the normative framework derived from the Bologna Declaration has set some trends of accreditation in Europe. It is clear that, in one way or another, this has influenced the development of varied quality assurance outlines in Latin America, as is demonstrated by the development of the QA actions identified on presented cases.

Abstract:

Globaliseringens och digitaliseringens framväxt har givit upphov till att människor har fått större tillgång till information. I syfte att underlätta hanteringen av massinformation kan bland annat tekniska hjälpmedel användas. Inom organisationer används bland annat tekniska kommunikationsverktyg för att underlätta informationsspridningen inom verksamheten. Fungerar inte kommunikationsverktygen i enlighet med sitt syfte och verksamhetens kommunikationsbehov kan de istället försvåra kommunikationen inom verksamheten. Vid en förstudie som har genomförts på företaget Briab har det visat sig att medarbetare upplevt att de interna kommunikationsverktygen inte fungerat tillräckligt väl för att underlätta företagets interna kommunikation. Utifrån resultatet av förstudien har denna studien har genomförts i syfte att ta fram förbättringsåtgärder för de interna kommunikationsverktygen på Briab. Förhoppningen var att effekterna av förbättrade interna kommunikationsverktyg även skulle bidra till att förbättra företagets interna kommunikation. Studien avgränsades till att undersöka de fyra centrala interna kommunikationsverktygen på Briab: intranätet, Briab Studio, Microsoft Teams och Microsoft Outlook. För att uppnå syftet med studien har en enkätundersökning genomförts på hela företaget. Resultatet av enkätundersökningen kartlade medarbetarnas kommunikationsbehov samt hur de deras upplevelse av respektive kommunikationsverktyg. Resultatet har visat att respondenterna upplever brister hos alla verktyg, men främst hos intranätet och Briab Studio. Respondenterna har bland annat beskrivit att det finns allt för mycket information som inte är uppdateras, att information inte har förmedlats på ett tillfredställande sätt och att det saknats kunskap för hur man ska använda vissa kommunikationsverktyg. Utifrån enkätsvaren har en analys genomförts genom släktskapsdiagram, där svaren kategoriserades och kartlade vilka två huvudproblem som respektive kommunikationsverktyg hade. I syfte att ta fram effektiva åtgärder har grundorsakerna för huvudproblemen hos kommunikationsverktygen kartlagts genom en workshop tillsammans med representanter från företaget. Grundorsakerna var bland annat bristande informationsägandeskap, kategorisering av information och riktlinjer för internkommunikation. Problemen hos de interna kommunikationsverktygen gav upphov till att bristande delaktighet hos Briabs medarbetare, informationsöverflöd resulterade i att medarbetare missade viktig information och bristande riktlinjer gjorde att medarbetare använde kommunikationsverktygen på olika sätt. Utifrån grundproblemen, teorier och medarbetarnas förslag på lösningar, har en åtgärdsplan tagits fram. Genom åtgärdsplanen uppnådde studien sitt syfte att ta fram förbättringsåtgärder för de interna kommunikationsverktygen. Briab har rekommenderats att vidare implementera åtgärderna och följa upp dess effekter för att förbättra de verktygen och förhoppningsvis den interna kommunikationen på företaget. The globalization and digitalisation have made information more avalible. In order to handle a huge amount of information, technical tools may be used. Within organizations, technical tools are at times used to facilitate dissemination of information. However, if the technical tools are not functioning for its purpose, the tool might insted aggravate the dissemination of information. A pilot study, accomplished at a company named Briab, showed that employeed felt unsatisfied with the technical communication-tools used within the company. Based on the result from the pilot study, this study has been done with the purpose to chart actions of impovements for the internal communcation-tools at Briab. The prospect of improved internal communication-tools was to contribute to improvement of the internal communication as a hole. The study was delimited to the four central communication-tools within Briab; the intranet, Briab Studio, Microsoft Teams and Microsoft Outlook. In order to achieve the purpose of the study, a survey was preformed upon the hole company. The result of the survey identified the needs for internal communication and the oponions regarding the internal communication-tools. The survey result showed that the respondents experianced defects regarding all of the internal communication-tools, yet mostly regarding the intranet and Briab Studio. The respondents did, among other, describe that to much information were not updated, that information were not mediated in a satisfying way and that the company lacked knowledge for how to communicate internally. Based on the results from the survey, analysis were done by the means of affinity diagrams, where the answers were categorised and the two main problems, of the respective communication-tools, were charted. In order to provide effective actions of improvements, the main causes of the problems were identified through a workshop together with representatives of the company. The main causes were identified as a lack of information-ownership, categorisation of information and guidelines for internal communication, among others. The problems with the internal communicaiton-tools generated in a lack of concern within the employees at Briab, overload of information resulted in employees missing out on important information and the lack of guidelines for internal communication opened to employees using the communication-tools in various ways. Based on the main problems, theories and the employees suggestion of improvement, an action plan of improvements was made. Through the action plan, the purpose of the study was achieved by charting actions of improvements for the internal communication-tools. Briab has been recomended to implement and follow up on the effect of the actions, in order to improve the communication-tools and hopefully improve the interal communication within the company.

Lehto, L. (Liisa). "Interactive two-step training and management strategy for improvement of the quality of point-of-care testing by nurses:implementation of the strategy in blood glucose measurement." Doctoral thesis, Oulun yliopisto, 2014. http://urn.fi/urn:isbn:9789526206707.

Full text

Abstract:

Abstract Point-of-care testing (POCT) is defined as laboratory tests performed outside the traditional clinical laboratory close to the patient at the time and place where care is received, such as hospitals and healthcare centers. The main reason for the use of POCT is that they provide rapid results and enable prompt interventions, with hopefully improved patient outcomes. All phases of laboratory procedure are included in POCT offering many opportunities for errors, which can influence on patients’ treatment. The measurements are more often performed by nurses than by laboratory professionals. These nurses have different kinds of professional backgrounds, e.g. public health nurses, registered and practical nurses, with minimal or no knowledge of laboratory procedures. The aim of the study was to develop a two-step training and management strategy for nurses to do POCT in hospital and primary healthcare center. In accordance with the strategy, with reasonable investment of laboratory resources, designated contact nurses were first trained in POCT by laboratory professionals, after which the contact nurses trained other nurses in POCT their respective units. Blood glucose, the most common point-of-care (POC) test, was chosen as an example to investigate the influence of training on the quality of the test performed by nurses. The quality of blood glucose measurements was studied by analyzing the control results obtained by nurses and biomedical laboratory scientists (BLSs). The study participants included nurses who were either untrained or trained to do POCT by using the developed interactive two-step training strategy. In conclusion, the nurses trained by using interactive two-step strategy achieved near-similar quality of blood glucose measurements as BLSs. The good quality of glucose measurements, once achieved by training, was also sustained in the long-term Tiivistelmä Määritelmän mukaan vieritutkimuksiksi kutsutaan laboratoriotutkimuksia, joita tehdään perinteisen laboratorion ulkopuolella, tarvittaessa lähellä potilasta sairaalassa ja perusterveydenhuollon alueella. Pääasiassa vieritutkimuksia tehdään silloin kun tulos halutaan saada nopeasti ennen hoitopäätöstä tai tulevaa toimenpidettä. Vieritutkimusten tekeminen sisältää kaikki laboratoriotyön vaiheet ja jokaisessa vaiheessa on mahdollisuus tehdä virheitä, jotka voivat vaikuttaa potilaiden hoitoon. Laboratorioammattilaisten sijaan määrityksiä tekevät yhä useammin hoitajat sairaalan eri yksiköissä ja perusterveydenhuollon alueella. Näillä hoitajilla on erilainen ammatillinen peruskoulutus, kuten perushoitajan tai sairaanhoitajan koulutus, ja heillä on vähän tai ei ollenkaan tietoa laboratoriomenetelmistä. Tämän tutkimuksen tarkoituksena oli kehittää hoitajien vieritutkimustoimintaan koulutus- ja hallintomalli, joka toimisi sekä sairaalassa että terveyskeskuksessa. Strategian perusteena oli käyttää suhteellisen vähän laboratorioresursseja ja päästä silti hyvään laadulliseen lopputulokseen. Strategiaksi valittiin kaksiportainen, vuorovaikutteinen koulutusmalli, jossa laboratorioammattilaiset kouluttivat sairaalan ja perusterveydenhuollon yksiköissä ns. yhdyshenkilöt, jotka puolestaan kouluttivat edelleen oman yksikkönsä muut hoitajat tekemään vieritutkimuksia. Veren glukoosimääritys, joka on yleisin vieritutkimus, valittiin esimerkkitutkimukseksi tutkittaessa koulutuksen vaikutusta hoitajien tekemien vieritutkimusten laatuun. Veren glukoosimääritysten laatutasoa tutkittiin analysoimalla hoitajien ja laboratoriohoitajien tekemien kontrollinäytteiden tuloksia. Tutkimukseen osallistui hoitajia, jotka oli koulutettu kehitetyllä vuorovaikutteisella kaksiportaisella koulutusstrategialla vieritutkimusten tekemiseen, sekä hoitajia, jotka eivät olleet saaneet vastaavaa koulutusta. Koulutusmallin avulla hoitajien suorittamien vieritutkimusten laatu parani ja he saavuttivat lähes saman laatutason kuin laboratoriohoitajat. Hyvä, kerran saavutettu glukoosimääritysten laatutaso säilyi myös pitkällä aikajaksolla

Abstract:

Det oundvikliga beroendet av digitalisering och IT-system i dagens verksamheter och organisationer ställer krav på dagens arbetskraft att öka sina IT-kunskaper för att kunna integrera och kommunicera med nya datasystem för en mer effektiv verksamhet. Inte minst lika viktigt blir det för redovisningsekonomer som sköter verksamhetens finansiella redovisning då de måste kunna säkerställa att den redovisningsdata som framställs och levereras med hjälp av IT är felfri och uppnår kvalitet. Bristen på kunskap inom IT kan riskera att fel i redovisningsdata inte upptäcks och därmed påverkar redovisningsdatakvalitet. Detta i sin tur riskerar påverka redovisningskvalitet i den slutliga finansiella rapporteringen. Kommunikationen mellan avdelningarna riskerar också bli lidande då de med olika kunskaper har svårt att förstå varandra.Studiens syfte är att försöka bidra med kunskap om hur kunskapsskillnader i digital gundkunskap kan påverka säkerställandet av redovisningsdatakvalitet samt ge insyn i hur arbetet med detta kan gå till i praktiken. Med hjälp av tidigare forskning togs en analysmodell fram som illustrerar identifierade faktorers påverkansordning av redovisningsdatakvalitet; kunskapsskillnader → intern kontroll → redovisningsdatakvalitet.Studien tillämpar en instrumentell fallstudiedesign med en kvalitativ forskningsansats för att besvara frågeställningen. Två fokusgruppsintervjuer utfördes vid två olika tillfällen med respondenter från redovisningsavdelningen och IT-avdelningen från samma företag. Data transkriberades och kodades med hjälp av färgkodning för att tydliggöra de faktorer som utgör utgångspunkten i analysmodellen. En enkätundersökning genomfördes på resterande anställda på respektive avdelning för att komplettera resultaten från intervjuerna.Resultatet av studien visade att kunskapsskillnaderna har liten eller ingen alls direkt påverkan på redovisningsdatakvalitet utan snarare påverkar den interna kontrollen desto mer utifrån externa faktorer som tillkom. The inevitable dependence on digitization and IT systems in today's operations and organizations demands the current workforce to increase their IT skills in order to be able to integrate and communicate with new computer systems for a more efficient business. It is equally important for financial accountants who’s responsible for the business’s financial reporting, since they must be able to ensure that the accounting data produced and delivered using IT is correct and of high quality. The lack of IT skills can increase the risk of errors in accounting data not detected and thus further affect the accounting data quality. This in turn risks affecting the accounting quality in the final financial reporting. The communication between the departments could also suffer due to the knowledge gaps between them that could make it difficult to understand each other.The aim of the study is to contribute with knowledge about how the differences in knowledge can affect the work in ensuring accounting data quality and give insight into how this work can be realized in practice. With the help of previous research, an analysis model was developed that illustrates identified factors and their influence on accounting data quality; knowledge gaps → internal control → accounting data quality.The study applies an instrumental case study with a qualitative research approach. Two focus group interviews were conducted on two different occasions with respondents from the accounting department and the IT department, both from the same company. Data was transcribed and coded using color coding to clarify the factors that form the basis of the analysis model. A survey was conducted with the other employees to complement and confirm the results found from the interviews.The result of the study showed that the differences in knowledge have little or no direct impact on accounting data quality, but rather affect the internal control, based on external factors that came into light during the analysis of the result. A revised analysis model was developed based on the result and replaced the initial hypothetical model.

Abstract:

Desenvolvimento Guiado por Testes (TDD) e uma das praticas sugeridas na Programacao Extrema. A mecanica da pratica e simples: o programador escreve o teste antes de escrever o codigo. E, portanto, possivel inferir que a pratica de TDD e uma pratica de testes de software. Entretanto, muitos autores de livros conhecidos pela industria e academia afirmam que os efeitos da pratica vao alem. Segundo eles, TDD ajuda o desenvolvedor durante o processo de criacao do projeto classes, fazendo-os criar classes menos acopladas e mais coesas. Entretanto, grande parte dos trabalhos da literatura sao voltados a descobrir se a pratica faz diferenca na qualidade do codigo gerado, mas poucos sao os autores que discutem como a pratica realmente auxilia. Mesmo os proprios praticantes nao entendem ou conseguem expressar bem como a pratica os guia. Este trabalho tem por objetivo compreender melhor os efeitos de TDD e como sua pratica influencia o desenvolvedor durante o processo de projeto de sistemas orientados a objetos. Para entende-las, neste trabalho optamos por um estudo exploratorio essencialmente qualitativo, no qual participantes foram convidados a resolver exercicios pre-preparados utilizando TDD e, a partir dos dados colhidos nessa primeira parte, nos levantamos detalhes sobre como a pratica influenciou as decisoes de projeto de classes dos participantes por meio de entrevistas. Ao final, observamos que a pratica de TDD pode guiar o desenvolvedor durante o processo de criacao do projeto de classes por meio de constantes feedbacks sobre a qualidade do projeto. Esses feedbacks alertam desenvolvedores sobre possiveis problemas, como alto acoplamento ou baixa coesao. Os desenvolvedores, por sua vez, devem interpretar e melhorar o projeto de classes. Este trabalho catalogou e nomeou os padroes de feedback percebidos pelos participantes. Test-Driven Development (TDD) is one of the suggested practices in Extreme Programming (XP). The mechanical is simple: the developer writes a test before writing the implementation. Thus, TDD is often seen as a software testing technique. However, many famous book authors suggest that TDD can help developers during the class design creation process, enabling developers to create less coupled highly cohesive classes. Most of the academic studies are interested on finding the difference between a TDDd and a non-TDDd code. Only a few of them discuss how the practice really supports class design. Even practitioners do not understand how the practice guides them. This work aims to understand better the effects of TDD and how the practice influences the practitioner during the class design process in object-oriented systems. To better understand them, we did a essencially qualitative explorative study, in which participants were invited to solve a set of pre-prepared exercises using TDD and, based on the gathered data, we retrieved details of how the practice influenced the developers class design decisions through interviews. At the end, we observed that the practice of TDD can guide developers during the class design creation process through constant feedback about its quality. These feedbacks alert developers about possible problems, such as high coupling or low cohesion. Developers then should interpret and improve the class design accordingly. This study also catalogues the TDD feedback patterns perceived by the participants.

Abstract:

This project was a step forward in improving the voltage profile of traditional low voltage distribution networks with high photovoltaic generation or high peak demand. As a practical and economical solution, the developed methods use a Dynamic Voltage Restorer or DVR, which is a series voltage compensator, for continuous and communication-less power quality enhancement. The placement of DVR in the network is optimised in order to minimise its power rating and cost. In addition, new approaches were developed for grid synchronisation and control of DVR which are integrated with the voltage quality improvement algorithm for stable operation.

Full text

Abstract:

Internal quality auditing (IQA) in the aerospace defense industry is not optional. Under Part 46 of the Federal Acquisition Regulation (FAR) all businesses providing product and services to the U.S. government are required to comply with their contract's quality requirements. The amount of compliance audits organizations receive are directly proportional to the number of government related contracts they possess. Therefore, most organizations are forced to focus IQAs on compliance to survive. The release of AS9100 international aerospace standards in 1999 was pivotal in eliminating these multiple audit requirements that plague the industry. However, the focus on IQA for compliance has remained rooted within the IQA system. Audit experts claim that recent updates included on AS9100 Rev C would change IQA's focus from auditing for compliance to auditing for effectiveness and performance.

Abstract:

This paper tries to identify and understand the human social obstacles for developing quality software. These include lip-service, cutting corners, deception and effects of internal politics. These obstacles can undermine the good intentions behind the software methodologies. The paper draws from the literature in different disciplines and uses an ethnographic research methodology to create a rich picture of the concerning aspects in the framework of one software development company in India. What stands out among the findings are that internal audits has mainly focused on finding errors in documentation procedures but study of the actual practices has often been shallow. In addition the understanding of business risks by the internal auditors have often been weak. Context. The human based obstacles affecting Software Development Methodology analysed in the context of an ISO 9000 quality system in an Indian Software Development company working mainly with Swedish companies. Objectives. Identifying and increasing the understanding of intrinsic negative social aspects such as lip service, cheating and politics which are affecting the results of Software Development Methodologies and if possible suggest some means to mitigate them. In particular to create a deeper understanding of why people cheat and pay lip service to methodologies and to try to understand the political aspects of methodology and quality systems. There are other positive social aspects, but they are not considered since the objective is about understanding the negative aspects and possibly mitigate them. Methods. Ethnographic research using analysis of ISO 9000 and design artefacts, semi-structured interviews, participation in internal audits, Results. Most focus in audits was on documentation and very less focus on underlying methodologies, some indications of lip-service to process and processes were also mainly managed on a higher level in the organization while the understanding and practices were less well established on lower level. It was hard to get a grip on the internal political aspects since the perception of the subject in the informants view was that it is mainly malicious and therefore embarrassing to speak about. Some conflicts between internal quality goals and customers’ needs were also identified. Conclusions. An ethnographic research methodology gives a rich picture. The analysis gives deeper understanding of the problem areas, but not necessary solutions. The author suggests that at the heart of the problem is a difference in world view. Software professionals generally tend to resolve [technical] problems using a reductionist approach, while these intricate challenges cannot easily be resolved by this approach. A more holistic systemic approach is required and while the software methodology is useful to structure the development it does not resolve these dysfunctions. They have to be resolved on another level. It was also found that further studies is required in particular to better understand Internal politics, the effect of Positive and Negative Incentives, the effect of software metrics on quality performance and subjectivity in customers’ perception and expectation. Uppsatsen försöker förstå mänskliga sociala hinder för att utveckla programvara med hög kvalitet. Dessa hinder inkluderar "läpparnas bekännelser", ta genvägar, vilseleda och internpolitik. Sådana hinder kan underminera utvecklingsmetoder. Denna uppsats bygger på literatur från olika discipliner och använder etnografisk forskningsmetodik för att skapa en rik bild av dessa oroande aspekter inom ramen för ett IT-företag i Indien. Vad står ut är att intern kvalitetsrevision fokuserar för mycket på att finna fel i dokumentationsprocesser medan revision av hur utvecklingsarbetet faktiskt sker har varit för ytligt. Dessutom har de interna revisorernas förståelse av affärsrisker varit svag.

Abstract:

This study asks what quality is and according to whom, through exploring the understandings of quality among stakeholders within a university’s internal quality assurance system. The focus is on teachers, students, and policy, as well as the difference between them. A case-study is made of two faculties within Uppsala University, with material based on both semi-structured interviews and text analysis of evaluation policy and assessor reports. The findings show a large focus on quality as goal fulfilment among both students and teachers. Ideas diverge where students focus more on relative quality and consistency, and teachers on transforming the students’ thinking. Policy is also focused upon goal fulfilment though kept relatively vague, inviting stakeholders to influence how quality is defined. Theoretical quality concepts from Harvey and Green (1993) are used and developed further in their practical application, with emphasis on the somewhat contested use of quality as consistency within the sphere of higher education. The findings also suggest a need for more explicit discussions between stakeholders regarding the view of quality within the university internal evaluations.

Abstract:

During the last two decades, ISO 9000 standards have become one of the most important management approaches in the world. Currently, the standards are used by more than one million companies in more than 170 countries. ISO 9001 audits are the most widely used performance measurement (PM) method to assess ISO 9001 quality management systems (QMS). However, in recent years the effectiveness of ISO 9001 quality auditing has been questioned for: (1) only focusing on compliance; (2) failing to detect problems in products and processes; (3) failing to predict QMS failures; and (4) failing to provide added value to organisations. To overcome these problems, two main conversations have taken place in the literature. The first advocates changing the current compliance focus of auditing for a performance oriented one, to promote improvements in business processes and the QMS. The second theme seeks to develop different methods, guidelines, tools and techniques to improve auditing practice. In order to generate a change of focus from compliance towards improvement, some recent research has also advocated incorporating concepts and techniques from the PM field into the ISO 9000 world. However, there have been no substantial previous attempts to provide internal quality auditing with a performance focus, which was the aim of this research. Hence, this thesis intends to establish how ISO 9001:2008 certified organisations can better measure their QMS performance using internal audits. In order to provide answers to this question, an empirical study using mixed methods research was conducted. Firstly, the current state of the art of the ISO 9001:2008 internal auditing process was determined using a mixed methods study, including two surveys of 272 ISO 9001 experts and 25 interviews. This allowed the identification of the current problems that ISO 9001 certified organisations face when conducting audits, as well as the impacts on the performance of the QMS due to deficient internal auditing. Secondly, using the statistical technique of path analysis, a model identifying the relationships between internal audit problems and their impacts on QMS performance was developed. The model indicated that an intricate network of individual and organisational deficits link auditing and QMS performance. Finally, ‘Audit+’ a detailed and comprehensive procedure for conducting ISO 9001:2008 internal audits with a focus on the performance of the QMS was developed. The procedure was thoroughly tested and validated by a further mixed methods study, including three in-depth case studies and a survey of 174 ISO 9001 auditors. Although some minor changes were recommended, the results of the Audit+ validation were encouraging, showing that PM approaches can be successfully incorporated into the ISO 9001 world, to help organisations to better measure their QMS performance.

Abstract:

Ce document présente la définition, le développement et l'évaluation d'une architecture P2P pour la diffusion de vidéo en direct. La conception est orientée vers la Qualité d'Expérience (QoE) au lieu de la traditionnelle Qualité de Service, via sa composante principale ici, la qualité perçue par les utilisateurs finaux. Nous étendons la méthodologie PSQA (pseudo—Subjective Quality Assessment) récemment proposée pour la mesure, automatique et temps réel, de la qualité vidéo perçue. Ensuite, nous proposons une technique de streaming multi-source avec une signalisation extrêmement faible. Nous décrivons une méthode de conception basée dans PSQA, qui permet un contrôle fin de la décomposition du stream en sous-streams, ainsi que de la redondance ajoutée, en fonction de la dynamique du réseau. Nous présentons également une structure arborescente de réseau permettant le contrôle de la topologie par optimisation de la qualité globale espérée (évalué en utilisant PSQA). Nous étudions comment étendre le réseau avec deux services complémentaires : vidéo à la demande et « MyTV » et proposons une stratégie de recherche dans les caches maximisant le nombre de réponses correctes aux requêtes sur les vidéos, étant donnée une dynamique particulière des contenus et des restrictions de bande passante. La conception globale de ces systèmes (architectures P2P, services associés) est basée dans des scénarios réalistes, avec des données réelles sur un service existant de distribution vidéo. Notre prototype comple��tement opérationnel est une application de logiciel libre, basée sur des technologies éprouvées et nos résultats de recherche, éxécutable sur plusieurs systèmes opératifs This document focuses on the definition, development and evaluation of a P2P architecture to deliver live video. The global design is driven by the Quality of Experience (QoE), instead of the traditional Quality of Service (QoS), through its main component here, the video quality perceived by final users. We extend the recently proposed Pseudo-Subjective Quality Assessment (PSQA) methodology allowing to measure, automatically and in real time, the perceptual video quality. Then, we propose a multi-source streaming technique with extremely low signaling overhead (opposite to current existing systems). We describe a design method based on PSQA, which allows a fine control of the way the video signal is split into substreams and of the amount of redundancy added, as a function of the networks dynamics. We also present a tree-based structured overlay allowing to control the topology by maximizing the global expected quality (evaluated using PSQA). We study how to extend the network with two complementary services : video on demand on MyTV. The challenge here is how to make video libraries efficiently searchable, because of the high dynamics in the contents. We propose a caching search strategy that maximizes the total number of correct answers to video queries, given a particular contents' dynamics and bandwidth constraints. Our global design for these systems focuses on realistic scenarios, using real data from of an existing video delivery service. Our full-working prototype is a completely free-software application, based on well-known technologies plus our own research results, which can be executed on various operating systems

Abstract:

Doutoramento em Educação - Supervisão e Avaliação O cenário atual sobre a temática da qualidade do ensino superior em Angola gera ainda preocupações, pese embora esforços que têm sido feitos pelos decisores nacionais no sentido de a legislar e operacionalizar. A avaliação da qualidade e a forma como os sistemas internos de garantia dessa qualidade podem facilitar a implementação de políticas e reformas estruturais no ensino superior em Angola constitui a questão central desta investigação. O estudo, de natureza exploratória com técnicas mistas de recolha de dados (inquérito por questionário, entrevista semiestruturada e análise documental), foi desenvolvido entre setembro de 2013 e março de 2014 em 7 províncias de Angola perfazendo o envolvimento de quatro instituições de ensino superior públicas. Analisamos os Planos de Desenvolvimento Institucional (PDI) das respetivas instituições, trabalhamos com uma amostra de 479 estudantes de licenciatura, 99 docentes que desempenhavam também funções de gestão intermédia, e 11 gestores e/ou responsáveis educativos de topo. Foi ainda feita a análise documental relevante para a temática, destacando-se a dos Planos de Desenvolvimento institucional das universidades envolvidas. O estudo evidencia que o fenómeno da qualidade no ensino superior é multivariado e dinâmico na medida em que as dimensões a serem tidas em conta são diferentes consoante os atores em causa. Por exemplo, para os estudantes, dimensões nucleares dessa qualidade são a “adequação da qualificação e perfil dos docentes”, a “adequação da qualificação e perfil do pessoal não docente”, para os docentes a “definição e garantia da qualidade formativa”, a “investigação e desenvolvimento”, e para os gestores de topo a “política e objetivos”, o “regime académico”, entre outros. Ainda assim surgem aspetos transversais aos três públicos inquiridos, nomeadamente a qualidade das estratégias de ensino-aprendizagem e avaliação usadas nas aulas. De salientar que os atores do estudo manifestaram e/ou identificaram aspetos da gestão da qualidade, por exemplo a investigação científica, que não correspondem à legislação nacional e internacional. Os resultados obtidos constituem pontos de discussão para uma reflexão mais fundamentada no sentido da melhoria dos sistemas internos de garantia de qualidade, em particular nas quatro instituições em causa, e a sua inclusão nos respetivos Planos de Desenvolvimento Interno. Podem igualmente constituir um promotor da operacionalização da implementação de mecanismos/estratégias de avaliação da qualidade nas instituições para as instituições de ensino superior das restantes províncias angolanas, nomeadamente daquelas que ainda não tiveram tempo de implementar os seus sistemas internos de garantia de qualidade, dada a recente expansão do ensino superior no nosso País. The current situation on the issue of quality of higher education in Angola still raises concerns, despite the efforts that have been made by national decision-makers towards legislating and operationalization. The quality evaluation and how internal systems of quality assurance facilitate the implementation of policies and structural reforms in higher education in Angola, is the central issue of this research. The study is exploratory and uses mixed techniques of data collection (inquiry by questionnaire and interview). The study was developed between September 2013 and March 2014 in 7 provinces of the Republic of Angola with the involvement of four public higher education institutions from that country. We work with a sample of 479 college students, 99 teachers who also combine middle management functions, and 11 managers who combine high management functions. It was also made a document analysis to the theme, highlighting the Internal Development Plans of each university involved. The results show that the phenomenon of quality in higher education is multivariate and dynamic and the dimensions to be taken into account are different depending on the perspective of each educational actor. For example, for the students quality nuclear dimensions are the "adequacy of qualification and profile of teachers", the "adequacy of qualification and profile of non-teaching staff"; for the teachers the nuclear dimensions are "define and guarantee quality training," "research and development "; and to high managers we can we find dimensions like "policy and objectives”, "academic system", among others. However, transversal aspects still arise among the three actors, namely the “quality of teaching-learning and evaluation strategies used in the classroom”. Should be noted that study of the actors expressed and / or identified quality management aspects, such as scientific research, which do not correspond to national and international legislation. The results we obtain from this research may constitute starting points to be discussed towards a more fundamental reflection for the improvement of internal quality assurance systems, in particular in the four institutions concerned, and their inclusion in the respective Internal Development Plans. The results may also promo the implementation of mechanisms/strategies to evaluate quality in higher education institutions of higher education institutions in other Angolan provinces, particularly in those which have not had time to implement their internal quality assurance systems, given the recent expansion of higher education in our country.

Abstract:

The air quality in the Ångström cleanroom was to be measured for monitoring and control purposes, with the measurements displayed on a website. To do this several sensors, micro controllers, means of communication, and ways to host the server were investigated. In the end the chosen components were the DHT12 sensor, Arduino Nano micro controllers, 433MHz LoRa modules for communication, and a Raspberry Pi for data aggregation and website hosting. Four edge nodes with sensors were placed in locations of interest and transmitted data to the central node that hosted the website. For the website a development methodology called AJAX was used to handle data, and the HTML canvas element was used to display data. The system as a whole met its requirements.

Abstract:

In Hong Kong, the responsibility for building management falls on property owners. To assist in building management, most property owners would appoint a property management company. Fulfilling relevant statutory requirements is mandatory for property management companies; however, it is debatable if meeting the basic statutory requirements is equivalent to providing quality property management services for property owners. In fact, property owners usually have more requests than minimum statutory requirements and it is therefore a multi-factor evaluation system for quality of residential property management services is proposed in this research project. To develop the assessment system, quality property management services criteria, including dimensions and performance items, are identified through desk research and focus group interviews with owners’ representatives and property management practitioners. Interval score and ranking are then assigned to the identified assessment criteria by distributing questionnaires with pilot test to owners’ representatives, property management practitioners and building management team of Home Affairs Department of HKSAR. Data collected from the questionnaire are analyzed with weight assessment method: Reliability Interval Method (RIM) in which importance weightings of the criteria can be developed and statistical analysis is allowed. “Repair and Maintenance (excluding clubhouse facilities, if applicable)” and “Effectiveness of emergency repair and maintenance services”, which are not statutory requirements for managing residential properties, are respectively weighted as the most important dimension and performance item. As far as application of the developed quality assessment system is concerned, services quality provided by major property management companies are measured and compared with questionnaires to students pursuing Housing Management in University of Hong Kong. The correlation between quality of property management services and numbers of properties managed by the company is not statistically significant; however, this is likely due to a small samples size, as the visual display of data suggests a relationship. One interesting finding in this research is the high factor weight of assessment criteria which are not statutory requirements for managing residential properties. Such a result implies that meeting basic statutory requirements is not equivalent to providing quality property management services in the eyes of property owners. Besides, this research provides a framework for future development of a classification system to indicate how good a property is for meeting specific overall grading. This research is important because quality of property management services in residential properties can be quantified and closely monitored with the developed quality assessment system in a performance-based, simple and standard way from the perspective of property owners. As far as the benefits of property management companies, which sell services in keen market, are concerned, it is expected that the system could keep supervising and thus improving the quality of services; delivery of high quality services is a profitable way to differentiate ones from the competitors. published_or_final_version Housing Management Master Master of Housing Management

Abstract:

This report is about implementing an Internet of Things (IoT) system that is meant to measure the water quality of the Nissan river located in Halmstad. The system measures the temperature, pH value, turbidity, dissolved oxygen, total dissolved solids and electrical conductivity of the water. The project is named Catfish, and the authors of the report are in the Data and Sensors team. The purpose of the Data and Sensors team is to program the prototype to collect the specified environmental values, combining all functionalities of the prototype in the main code, and sending the data wirelessly to a database in real-time, including creating the database. To collect the data, two Arduino microcontrollers and sensors from DFRobot are used. For the central computing, a Raspberry Pi is used. To send the data in real-time, a 4G dongle is connected to the Raspberry Pi and to transmit the data, the protocol TCP/IP is used. In order to create a local database, SQLite is used, and for the database server, MariaDB is used. The project has succeeded to collect data from the specified sensors, send the data wirelessly over the Internet with the help of a 4G modem, and store the data in a database on a remote temporary server. However, the sensors are not calibrated due to lack of time, which means the data received from the sensors can not be trusted. The server that stores the data is a temporary server implemented by the Data and Sensors team since there was no other place to store the data. Denna rapporten handlar om en implementation av ett Internet of Things (IoT) system som är menad för att mäta vattenkvalitéen i Nissan i Halmstad. Systemet mäter temperaturen, pH värde, grumlighet, upplöst syre, totalmängden upplösta ämnen och elektrisk konduktivitet i vattnet. Detta projektet heter Catfish och författarna av denna rapport är del av Data och Sensor gruppen. Syftet av Data och Sensor gruppen är att programmera prototypen till att samla de specifierade miljövärdena, kombinera prototypens funktioner i huvud-koden och att skicka datan till en databas trådlöst och i real-tid, vilket inkulderar att skapa databasen. För att samla datan används två Arduino mikrokontrollers och sensorer från DFRobot. För den centrala datoranvändningen används en Raspberry Pi. För att skicka data i realtid används ett 4G modem som kopplas till Raspberry Pi:n och skickar datan till servern genom TCP/IP. Skapandet av en lokal databas är gjord i SQLite och för databasen i servern används MariaDB. Projektet har lyckats med att samla data från de specifierade sensorerna, skicka datan trådlöst över Internetet med hjälp av ett 4G modem och lagra datan i en databas i en temporär fjärrserver. Sensorerna är dock inte kalibrerade på grund av tidsbrist, vilket betyder att man inte kan lita på datan från sensorerna. Servern där datan lagras är temporär och implementerad av Data och Sensor gruppen eftersom det inte fanns någon annanstans att lagra datan.

Abstract:

De nos jours, Internet est devenu indispensable dans le quotidien des humains. Aujourd’hui, ce réseau sert entre autres de plate-forme de communication, de système transactions et de divertissement. Ces activités sont possibles grâce à des composants satellites qui gèrent les flux d'informations. Dans ce contexte, l'intérêt des fournisseurs de communications satellites est d'améliorer la satisfaction des clients à travers d'utilisation optimale de ces ressources. La qualité de service (QDS) est utilisée pour accomplir cet objectif. Améliorer la QDS permet la réduction des erreurs liées à la perte et la latence paquets; par conséquent “la qualité de service” (QDS) aide à optimiser le trafic internet. En fonction du trafic internet (Streaming, VoIP, Transfert de fichiers, etc.) et de ses erreurs, le flux de paquet peut être classé parmi plusieurs catégories. En suivant cette idée, ce projet de thèse vise à trouver des nouvelles approches de classification du trafic Internet pour améliorer la QDS.Pour classifier le trafic Internet, l'apprentissage automatique sera étudié et déployé. Les composants qui permettront de coupler une solution d'apprentissage automatique avec une architecture satellite et de qualité de service seront évalués. Dans cette architecture, un ou plusieurs points de surveillance capteront le trafic Internet. Des techniques de classifications marqueront le trafic capté en classes qui seront interprétées par l'architecture de la qualité de service.Pour développer notre solution, une base de données riche et complète sera requise; toutefois, les données historiques labellisées sont difficilement disponibles pour le public. Dans ce contexte, des paquets binaires seront extraits et stockées pour générer un historique de données. Par conséquent, une plate-forme d'émulation du trafic Internet sur le cloud pour générer des flux de communication a été proposée. Cela sera aussi implanté sur une plateforme d'émulation de communication Satellite. En outre, des flux IP devront être construits avec les paquets et quelques caractéristiques statistiques pour discriminer et décrire le trafic Internet correctement seront présentées. Ensuite, un système de classification sera capable de gérer différentes communications sur Internet (cryptées, non cryptées et en tunnel). Ce système traitera le trafic entrant de manière hiérarchique pour atteindre une performance de classification élevée. Par ailleurs, pour faire face à l'évolution des applications Internet, une nouvelle méthode est présentée pour induire des mises à jour au système de classification initiale. Finalement, des expériences sur la plate-forme émulée dans le cloud seront mises en place pour valider notre proposition et définir des directives pour son déploiement sur l’architecture Satellite The Internet has become indispensable for the daily activities of human beings. Nowadays, this network system serves as a platform for communication, transaction, and entertainment, among others. This communication system is characterized by terrestrial and Satellite components that interact between themselves to provide transmission paths of information between endpoints. Particularly, Satellite Communication providers’ interest is to improve customer satisfaction by optimally exploiting on demand available resources and offering Quality of Service (QoS). Improving the QoS implies to reduce errors linked to information loss and delays of Internet packets in Satellite Communications. In this sense, according to Internet traffic (Streaming, VoIP, Browsing, etc.) and those error conditions, the Internet flows can be classified into different sensitive and non-sensitive classes. Following this idea, this thesis project aims at finding new Internet traffic classification approaches to improving customer satisfaction by improving the QoS.Machine Learning (ML) algorithms will be studied and deployed to classify Internet traffic. All the necessary elements, to couple an ML solution over a well-known Satellite Communication and QoS management architecture, will be evaluated. In this architecture, one or more monitoring points will intercept Satellite Internet traffic, which in turn will be treated and marked with predefined classes by ML-based classification techniques. The marked traffic will be interpreted by a QoS management architecture that will take actions according to the class type.To develop this ML-based solution, a rich and complete set of Internet traffic is required; however, historical labeled data is hardly publicly available. In this context, binary packets should be monitored and stored to generate historical data. To do so, an emulated cloud platform will serve as a data generation environment in which different Internet communications will be launched and captured. This study is escalated to a Satellite Communication architecture. Moreover, statistical-based features are extracted from the packet flows. Some statistical-based computations will be adapted to achieve accurate Internet traffic classification for encrypted and unencrypted packets in the historical data. Afterward, a proposed classification system will deal with different Internet communications (encrypted, unencrypted, and tunneled). This system will process the incoming traffic hierarchically to achieve a high classification performance. Besides, to cope with the evolution of Internet applications, a new method is presented to induce updates over the original classification system. Finally, some experiments in the cloud emulated platform validate our proposal and set guidelines for its deployment over a Satellite architecture

Abstract:

Globalization creates for companies’ new opportunities for business development, as well as new challenges. One of the most prevailing challenges is the ability to create new products and services in accordance to diverse customer needs and requirements, as well as implementation of new technologies in future lines of products. Therefore, companies realize the importance of the Marketing and Sales (M&S) and Product Development (PD) departments. The interface between those two departments plays a decisive role in realization of customer needs and requirements, and application of the right technologies in new products. The speed and accuracy with which the information between the M&S and PD department is exchanged directly influences success of one’s products on the market. Consequently, companies strive to achieve greater level of cross-functional integration within the interface, by overcoming barriers to integration, and improving the quality of internal services by utilizing computer based Information Systems (IS). The role of IS in supporting cross-functional work environment is growing, thus companies of all size make investment in IS. Nonetheless, these investments very often fail or not bear expect results, due to lack of alignment of the investment with the business.This thesis documents a diagnosis undertaken for the Case Company. In recent years the Case Company experienced rapid international expansions and fast growth, which in turn exposed a whole new range of problems. The existing work routines turned out to be inadequate to maintain international expansion and growth. A great deal of these problems was enrooted directly in the interface between the M&S and PD departments. Therefore, the company realized a need to isolate and eliminate them, and further foster the cross-functional integration and information flows within the interface by implementation of a computer based Information System.The purpose of this thesis is to enhance the understanding of the integration and communication process within the M&S and PD departments at the Case Company. In order to fulfil the purpose the Enterprise Knowledge Development modelling technique was employed. This allowed tracing the problems to their roots, by mapping business processes, goals, rules, actors, as well as clarification of concepts. As a result an objective snapshot of the current cross-functional integration between the M&S and PD departments was created. Further, this snapshot was compared against a great body of literature in the field of Product Development and Management and Process Management. The comparison made it possible to indicate areas for potential future improvements. The proposed change needs aimed at enhancing the internal customer satisfaction. Last but not the least in deep analysis of the current cross-functional relations within the interface made it feasible to suggest (with literature assistance) initial vital functions of a computer based Information System to enhance the integration and information flows within the studied interface at the Case Company. The proposed functionality corresponds to the current, as well as anticipated needs of the interface that has been derived based on requirements of the actors to fulfil goals and satisfy organizational processes.

Sammanfattning Titel: Kvalitetscertifiering i mindre företag – Interna, externa eller finansiella motiv? Nivå: Examensarbete på Grundnivå (kandidatexamen) i ämnet företagsekonomi Författare: Casper Wessén och Daniel González Handledare: Tomas Källquist och Pär Vilhelmson Datum: 2019 - juni Syfte:Syftet med denna studie är att öka förståelsen för de bakomliggande motiven till att ledningen i mindre företag väljer att kvalitetscertifiera verksamheten mot ISO 9001. Metod: Studien utgår från en socialkonstruktivistisk verklighetssyn och en hermeneutisk tolkande kunskapssyn. Källkritisk litteratursökning har framställt en teoretisk referensram, vilket samtidigt har synliggjort studiens empiriska datainsamlingsmetod. Studien antar en abduktiv forskningsansats, alltså en samverkan mellan teori och empiri. Empirin i sin tur samlades in genom kvalitativa semistrukturerade intervjuer med tio mindre företag. För att kvalitetssäkra studien synliggjordes fyra kvalitetskriterier, vilka alla har spelat en avgörande roll för studiens helhet. Resultat & slutsats: Studien har primärt fokuserat på att besvara syftet. Utifrån framställningen av teoretisk referensram synliggörs de motiv som i huvudsak benämns i tidigare forskning. Därefter lyfts de bakomliggande motiv som illustrerades genom vald datainsamlingsmetod fram. De jämförs i kapitlet analys för att påvisa hur empirisk datainsamling har ökat förståelsen för bakomliggande motiv, vilket var studiens avsikt. Examensarbetes bidrag:Ett teoretiskt bidrag ges dels i form av en strukturering i underkategorier av de motiv som påvisades i tidigare forskning, dels i form av nya synliggjorda underkategorier utifrån empirisk datainsamling. De nya framställda underkategorierna har hjälpt till att strukturera de bakomliggande motiv som inte nämnts i tidigare forskning, men som vår insamlade empiri påvisade att ledningen haft till certifiering av sitt företag mot ISO 9001. Förslag till vidare forskning: Forskning skulle kunna ta vid denna studie genom att använda de underkategorier ur framställd modell som utgångspunkt för att synliggöra huruvida fler mindre företag även har dessa som bakomliggande motiv. Ytterligare förslag är att studera motiv till att fortsätta vara certifierad, då kostnaderna ständigt ökar allt eftersom standarden förnyas. Även att ställa den tid och de resurser som läggs ner på att certifiera ett företag mot den nytta certifieringen faktiskt ger skulle vara intressant att ta vid. Abstract Title: Quality certification in smaller companies – Internal, external or financial motives? Level: Student thesis, final assignment for Bachelor Degree in Business Administration Authors: Casper Wessén and Daniel González Supervisors: Tomas Källquist and Pär Vilhelmson Date: 2019 - June Aim: The purpose of this study is to increase the understanding of the management in small companies underlying motives to quality certificate the business against ISO 9001. Method: The study is based on a social constructivist view of reality and a hermeneutic view of knowledge. Source-critical literature search has produced a theoretical frame of reference. The frame then helped decide the study's empirical data collection method. The study is conducted with an abductive research approach, which is a collaboration between theory and empirical data. The empirical data in turn, was collected through qualitative semi-structured interviews with ten smaller companies. To assure the quality of the study, four quality requirements were made visible, which all played a crucial role for the whole of the study. Result & conclusions: The study has primarily focused on answering its purpose. Based on the theoretical frame of reference, the motives from previous research were made visible. Then the underlying motives illustrated by our empirical data collection method were highlighted.They are then compared in the chapter analysis to demonstrate how empirical data collection has increased the understanding of underlying motives, which was the study's intention. Contribution of the thesis: A theoretical contribution is given partly in the form of a structuring in subcategories of the motives that were demonstrated in previous research, partly in the form of new visible subcategories based on empirical data collection. The new subcategories have helped to structure the underlying motives that were not mentioned in previous research, but our empirical evidence showed that the management had to certify its company against ISO 9001. Suggestions for further research: Research could take on this study by using the model presented in the result as a starting point to visualize whether other small companies also seem to have had these underlying motives. Additional suggestions are to study motives to continue to be certified, as costs are constantly increasing as the standard is renewed. It would also be interesting to take the time and resources spent on certifying a company against the benefit of the certification.

Abstract:

In less than a generation, the World Wide Web has grown from a relatively small cyber play-ground of academic "geeks" into an 11.5 billion-page collection of heterogeneous, inter-connected, network of information and collective knowledge. As an information environment the World Wide Web is informatically representative of all that is good and bad about the human need to both absorb and transmit knowledge. The 'open' nature of the Web makes instantly available to anyone who can "log-on", a boundless digital library of information, the quality of which cannot be enforced before, during, or even after its publication. Scrutiny of Information Quality (IQ), is therefore left up to those publishers conscientious enough to care about the quality of the information they produce and the users who choose to employ the Web as an information retrieval tool. The following thesis is a qualitative investigation of how the users of information make value-judgments about the information they encounter and retrieve from the Web. Specifically, it examines perceptions of IQ from the perspective of eighty "academic" high-end users, who regularly engage the Web and its search engines to search for and retrieve high-quality information related to their research, teaching and learning. The investigation has adopted an inductive approach in the qualitative analysis of quantitative ( 10,080 separate pieces of user-data) data in the context of such established frameworks as Davis' ( 1986, I 989) Technology Acceptance Model (TAM), and Wang & Strong's ( 1996) contextual IQ framework that conceptualised dimensions of quality into four IQ categories, namely: intrinsic; representational; contextual; and accessibility IQ. Through the detailed analysis of the driving theory behind these, and other associated models of: (I) user IT acceptance; (2) Information Seeking Behaviour (ISB}; and (3) multi–dimensional characteristics of IQ; the researcher has sought to find synergies and develop an innovative framework by which to explore the impact of users' attitudes, expectations and perceptions of IQ on their Web information retrieval behaviours. The findings associated with the thesis are consistent with the proposal of a new Ongoing Technology Acceptance Model (OTAM), which facilitates the measurement of users perception of the predictability of their technology interactions, and has the capacity to more accurately investigate user individual differences. Importantly, the OTAM allows the constructs of the original TAM, along with a new construct “Perception of Interaction" (Pol) to be used to investigate users ongoing use of technologies. Findings associated with user perceptions of information quality are also explored and discussed in relation to a proposed life-cycle model of IQ.

Abstract:

La confiance et l'incertitude sont deux aspects importants des systèmes distribués. Par exemple, de multiples sources d'information peuvent fournir le même type d'information. Cela pose le problème de sélectionner la source la plus fiable et de résoudre l'incohérence dans l'information disponible. Gérer de front la confiance et l'incertitude constitue un problème complexe et nous développons à travers cette thèse, une solution pour y répondre. La confiance et l'incertitude sont intrinsèquement liés. La confiance concerne principalement les sources d'information alors que l'incertitude est une caractéristique de l'information elle-même. En l'absence de mesures de confiance et d'incertitude, un système doit généralement faire face à des problèmes tels que l'incohérence et l'incertitude. Pour aborder ce point, nous émettons l'hypothèse que les sources dont les niveaux de confiance sont élevés produiront de l'information plus fiable que les sources dont les niveaux de confiance sont inférieurs. Nous utilisons ensuite les mesures de confiance des sources pour quantifier l'incertitude dans l'information et ainsi obtenir des conclusions de plus haut niveau avec plus de certitude.Une tendance générale dans les systèmes distribués modernes consiste à intégrer des capacités de raisonnement dans les composants pour les rendre intelligents et autonomes. Nous modélisons ces composants comme des agents d'un système multi-agents. Les principales sources d'information de ces agents sont les autres agents, et ces derniers peuvent posséder des niveaux de confiance différents. De plus, l'information entrante et les croyances qui en découlent sont associées à un degré d'incertitude. Par conséquent, les agents sont confrontés à un double problème: celui de la gestion de la confiance sur les sources et celui de la présence de l'incertitude dans l'information. Nous illustrons cela avec trois domaines d'application: (i) la communauté intelligente, (ii) la collecte des déchets dans une ville intelligente, et (iii) les facilitateurs pour les systèmes de l'internet du futur (FIWARE - le projet européen n° 285248, qui a motivé la recherche sur nos travaux). La solution que nous proposons consiste à modéliser les composants de ces domaines comme des agents intelligents qui incluent un module de gestion de la confiance, un moteur d'inférence et un système de révision des croyances. Nous montrons que cet ensemble d'éléments peut aider les agents à gérer la confiance aux autres sources, à quantifier l'incertitude dans l'information et à l'utiliser pour aboutir à certaines conclusions de plus haut niveau. Nous évaluons finalement notre approche en utilisant des données à la fois simulées et réelles relatives aux différents domaines d'application Trust and uncertainty are two important aspects of many distributed systems. For example, multiple sources of information can be available for the same type of information. This poses the problem to select the best source that can produce the most certain information and to resolve incoherence amongst the available information. Managing trust and uncertainty together forms a complex problem and through this thesis we develop a solution to this. Trust and uncertainty have an intrinsic relationship. Trust is primarily related to sources of information while uncertainty is a characteristic of the information itself. In the absence of trust and uncertainty measures, a system generally suffers from problems like incoherence and uncertainty. To improve on this, we hypothesize that the sources with higher trust levels will produce more certain information than those with lower trust values. We then use the trust measures of the information sources to quantify uncertainty in the information and thereby infer high level conclusions with greater certainty.A general trend in the modern distributed systems is to embed reasoning capabilities in the end devices to make them smart and autonomous. We model these end devices as agents of a Multi Agent System. Major sources of beliefs for such agents are external information sources that can possess varying trust levels. Moreover, the incoming information and beliefs are associated with a degree of uncertainty. Hence, the agents face two-fold problems of managing trust on sources and presence of uncertainty in the information. We illustrate this with three application domains: (i) The intelligent community, (ii) Smart city garbage collection, and (iii) FIWARE : a European project about the Future Internet that motivated the research on this topic. Our solution to the problem involves modelling the devices (or entities) of these domains as intelligent agents that comprise a trust management module, an inference engine and a belief revision system. We show that this set of components can help agents to manage trust on the other sources and quantify uncertainty in the information and then use this to infer more certain high level conclusions. We finally assess our approach using simulated and real data pertaining to the different application domains

Abstract:

The purpose of this research is to develop best practices for deploying air quality sensors in a remote location such as Mongolia. I discussed the architecture and design constraints when collecting remote air quality sensors data, the challenges that emerge while implementing a sensor-based network in a remote location such as Mongolia. The tradeoffs of using different architectures are described. I observed the usage of electrical heaters in modified gers in remote locations and conclude how effective they are in reducing PM2.5 levels by analyzing air quality data and go through the process of cleaning up the data and removing humidity from low-cost sensors used to deploy in a remote location such as Mongolia so that the PM2.5 reading is more accurate. In order to help many humanitarian efforts dealing with better air quality in developing countries, an air quality sensor was designed to keep low cost as much as possible. The cost is about $200 to build, which is cheaper than other low-cost sensors, yet provides more functionality (e.g., CO2 sensing) and used cellular connectivity to upload data in real-time. This sensor has implications beyond Mongolia. The sensor can be used anywhere WiFi connectivity is not available, such as parks, bus stops, and along roadways, breaking the constraints that other low-cost sensors have. Removing the need for WiFi is a necessary step in allowing ubiquitous air quality sensing. The contributions in this thesis are: First, I presented the challenges one should consider while deploying air quality sensors in developing countries. Second, since Mongolia offers a unique environment and constraints, I shared experiences in deploying sensors in a remote location like Mongolia. This experience goes beyond air quality sensors and can inform anyone who is deploying sensors in remote areas. Third the analysis of the PM2.5 on the gers gives us better insights as to whether modifying gers with insulation and using electrical heaters as opposed to burning coal to heat up the gers makes a difference in regard to better air quality in the gers.

Abstract:

La prolifération de l'Internet des objets (IoT) a transformé les espaces traditionnels en environnements plus intelligents et interconnectés. Cela a donné lieu à des systèmes IoT sophistiqués, généralement composés de dispositifs qui détectent des phénomènes physiques et génèrent des données pouvant être traitées par des nœuds de calcul avant d'être consommées par des applications. Ces applications définissent généralement des exigences spécifiques de qualité de service (QoS) qui doivent être respectées (par exemple, disponibilité, précision, latence). À cette fin, les systèmes IoT sont souvent configurés pour garantir que les exigences de QoS des applications déployées soient respectées. Cela implique l'ajustement de plusieurs paramètres tels que les configurations réseau, les ressources de traitement, et l'optimisation des systèmes d'échange de données. Cependant, les espaces intelligents modernes sont intrinsèquement dynamiques et imprévisibles. Les variations dans le nombre de dispositifs IoT, les conditions du réseau, et les ressources de calcul disponibles créent un environnement en constante évolution. Ainsi, pour garantir que les systèmes IoT fonctionnent de manière autonome, il est essentiel de concevoir des mécanismes d'auto-adaptation pour maintenir les exigences de QoS des applications dans des situations dynamiques. Cette thèse propose une approche d'auto-adaptation à base d'intergiciel et d'intelligence artificielle (IA) hybride pour permettre des opérations autonomes des systèmes IoT dans des environnements dynamiques. En combinant des approches basées sur la logique avec des techniques d'IA basées sur les données, nous concevons des solutions d'auto-adaptation efficaces et explicables pour les systèmes IoT. Cela est réalisé à travers trois contributions principales. Tout d'abord, des réseaux de files d'attente sont utilisés pour composer des modèles de QoS qui représentent les systèmes IoT sous différentes situations et/ou configurations. En simulant ces modèles de QoS, nous sommes en mesure de générer des ensembles de données de performances qui peuvent être utilisés dans des approches auto-adaptatives pour s'adapter dynamiquement aux situations changeantes en sélectionnant la configuration qui satisfait le mieux les exigences de QoS définies par les applications. La deuxième contribution permet une gestion adaptative des flux de données pilotée par l'IA dans les espaces IoT. En combinant des techniques d'IA basées sur la logique et sur les données, telles que l'IA planning et l'apprentissage par renforcement, nous concevons un cadre impliquant des agents intelligents capables de prendre des décisions d'adaptation en temps réel. Les actions d'adaptation possibles incluent les configurations de flux de données (par exemple, priorités, taux de rejet de données) et le contrôle des ressources (par exemple, ressources réseau, ressources de calcul). Enfin, la dernière contribution permet de rendre les systèmes autonomes plus proactifs et explicables grâce à l'apprentissage par renforcement et la théorie de la causalité. Pour ce faire, nous nous appuyons sur le cadre de la causalité afin de fournir une analyse formelle des performances des systèmes IoT. Par la suite, les modèles causaux permettent un processus de prise de décision plus efficace, permettant aux agents d'adaptation de prendre des actions d'adaptation efficaces dans des environnements dynamiques. Nous validons notre approche en développant une implémentation prototype d'un système IoT et en menant des expériences sur des études de cas considérant différents types d'environnements IoT. Nos modèles de QoS sont évalués et comparés à une implémentation prototype pour valider la précision des ensembles de données de performances générés. Nous évaluons ensuite l'efficacité de notre solution en exploitant des données issues de déploiements réels pour nous assurer que notre approche est valide dans des contextes réels The proliferation of Internet of Things (IoT) devices has transformed traditional spaces into smarter, more interconnected environments. These advanced IoT systems consist of devices that sense physical phenomena and generate data, which are then processed by computing nodes before being used by applications. Such applications typically define specific Quality-of-Service (QoS) requirements, such as availability, accuracy, and latency, that must be met. To achieve this, IoT systems are normally configured to ensure that the QoS requirements of the deployed applications are met. This involves adjusting multiple parameters such as network settings, processing resources, and tuning data exchange systems. However, modern smart spaces are inherently dynamic and unpredictable. Changes in the number of IoT devices, network conditions, and available computational resources create a continuously evolving environment. Thus, to ensure that IoT systems operate autonomously, it is essential to design advanced self-adaptive mechanisms for maintaining QoS requirements of applications across dynamic smart spaces.This thesis proposes a middleware-based, hybrid Artificial Intelligence (AI) self-adaptation approach for enabling autonomous IoT operations across dynamic smart spaces. By combining logic-based approaches with data-driven AI techniques, we design effective and explainable self-adaptation solutions for IoT systems operating over dynamic environments. This is achieved through three main research contributions. First, queueing network modeling techniques are leveraged to compose QoS models that represent IoT systems under different situations and/or configurations of smart spaces. By simulating QoS models, we generate performance metrics datasets that can be used as input in self-adaptive approaches. These approaches dynamically adjust to changing conditions by selecting the configuration that best meets the QoS requirements specified by the applications. The second contribution enables AI-driven adaptation of IoT systems in smart spaces. By combining AI techniques such as Automated Planning and Reinforcement Learning, we design a framework involving intelligent agents capable of taking adaptation decisions at runtime. Possible adaptation actions include data flow configurations (e.g., priorities, drop rates) and resource control (e.g., network resources, computing resources). Finally, the third contribution enables proactive and explainable autonomous systems by relying on Causal Reinforcement Learning. To achieve this, Causality methodologies are employed to provide a formal analysis of the performance of IoT systems. Subsequently, causal models enable agents to take efficient adaptation actions in dynamic environments. We validate our proposed approach by developing a prototype implementation of an IoT system and experimenting with case studies considering different types of IoT environments. Our QoS models are evaluated and compared with a prototype implementation for validating the accuracy of the generated performance metrics datasets. We then evaluate the effectiveness of our solution by leveraging data from real deployments to ensure that our approach is valid in real-life settings. The self-adaptation approach presented in this thesis can be exploited to design resilient and modern IoT systems where interactive and real-time services are required, enabling smart spaces to autonomously adapt to changes in their environment, and ensuring optimal performance even under dynamic conditions

Abstract:

Den reviderade versionen av standarden för kvalitetsledningssystem, ISO 9001, publicerades i september 2015. Tidigare forskning visar att flera undersökningar har funnit en positiv inverkan av ISO 9001 medan andra studier inte kunnat fastställa detta resultat. Syftet med studien var att undersöka de främsta förändringarna i reviderade ISO 9001 som uppfattades möta företags och organisationers interna kunders behov. En kvalitativ undersökning genomfördes i form av intervjuer med tio respondenter. Resultatet av intervjuerna visade att standarden ansågs ge förutsättningar för att kunna bygga ett kvalitetsledningssystem som är anpassat till behoven i organisationen. I den reviderade standarden har ledningen ett tydligare ansvar för kvalitetsledningssystemet vilket är den förändring som främst uppfattades möta de interna behoven. Studiens resultat är ett bidrag till företag och organisationer som önskar öka sin kunskap om vilken kundnytta ISO 9001:2015 kan bidra med till de interna kunderna. The revised version of the standard for quality management, ISO 9001, was published in September 2015. Previous research has shown that several studies have found a positive effect of the standard while other studies have not been able to determine this result. The aim of the study was to examine if the main changes in the revised ISO 9001 was perceived to meet companies and organizations internal customers needs. A qualitative study was conducted in the form of interviews with ten respondents. The result of the interviews showed that the standard was considered to provide the conditions to build a quality management system that is tailored to the needs of the organization. In the revised standard, management has a clear responsibility for the quality management system which was the change that was primarily conceived to meet the internal needs. The results of the study are a contribution to companies and organizations that wish to increase their knowledge aboutthe customer benefits which ISO 9001: 2015 may contribute to the internal customers.

Abstract:

De part son support du facteur d’échelle et son faible coût de déploiement, le modèle Pair-à-Pair (P2P) est un excellent support pour les applications de diffusion vidéo sur Internet. Toutefois, étant donné que ce modèle inclue dans la diffusion de contenu les hôtes finaux contrôlés par les utilisateurs, le comportement de ces derniers impacte directement la performance de ces applications induisant des problématiques de qualité de service. Dans cette thèse, nous intégrons le comportement de l’utilisateur pour l’amélioration de performance des systèmes pair-à-pair de diffusion de contenu vidéo en direct. Tout d’abord, nous présentons une synthèse des mesures à grande échelle qui nous permet de comprendre le comportement d’un utilisateur dans sa globalité. Nous présentons ensuite deux modèles. Le premier modèle, non-contextuel, s’appuie uniquement sur l’historique des sessions passées. Il est basé sur deux méthodes statistiques, l’une basée sur la moyenne mobile et l’autre sur l’inférence Bayésienne. Le second modèle est un réseau Bayésien qui considère toutes les variables identifiées dans la synthèse des mesures. Nous validons ce modèle par simulation sur des traces de comportements réalistes générés synthétiquement à partir d’un modèle semi-Markovien. Nous proposons enfin deux stratégies pour stabiliser la topologie d’un réseau P2P et analysons l’amélioration de la performance par expérimentations dans un réseau local et sur PlanetLab et montrons le gain apporté par nos travaux Potential scalability and low deployment cost of the Peer-to-Peer (P2P) architecture makes it a favorable choice for video streaming services. P2P systems involve end-hosts, called peers, in the stream delivery task by turning them into relays. Since peers are controlled by users, their behavior directly impacts the performance of these systems. Current approaches lack a comprehensive consideration of user behavior, hence suffering from Quality-of-Service issues. In this thesis, we focus on user behavior for performance improvement of P2P live streaming systems. To precisely understand the user behavior, we perform a synthesis of its measurements and based on it, we propose both a non-contextual and a contextual model. The former model includes two statistical methods, one based on exponential moving average and the other on Bayesian inference. Both of them only rely on the history of past sessions. The later model consists in a Bayesian network model that takes into account all variables identified in user behavior measurements. We validate our model through simulations over synthetic traces of realistic user behaviors generated through a semi-Markovian model. Finally, we propose two strategies that make use of our models to make P2P live streaming systems user-aware. These mechanisms are aimed at the stabilization of the overlay. Experiments in a LAN environment and over PlanetLab show that our approaches significantly improve the performance of an existing system

Abstract:

This work presents the results of different numerical and experimental studies about energy performance, thermal comfort and ventilation effectiveness of radiant systems combined with different types of mechanical ventilation. Experimental studies have been carried out in Italy, in a test room in the laboratories of the company RHOSS S.p.A in Codroipo (Udine) and in Denmark, in a test room in the laboratories of the International Centre for Indoor Environment and Energy (ICIEE), at DTU (Danish Technical University), in Lyngby. Radiant systems in residential and in office buildings are increasingly used because of the low heating or cooling demand and, at the same time, for the good thermal comfort they assure. The thermal output estimation of radiant system in steady state condition needs the determination of the convective heat transfer coefficient from the surface to the room; a critical review among the correlations available in literature have been carried out and correlations for heated ceiling and cooled floor have been presented. Furthermore the variation of convective heat transfer coefficients, depending on the considered ventilation systems, has been estimated by means of the Computational Fluid Dynamics (CFD) technique. The energy performance and thermal behavior of radiant systems during transient conditions have been predicted by using experimental tests and numerical calculations with the software Digithon that was developed by the University of Padua. In this work the validation of this software by comparison with experimental data has been presented. In new and renovated buildings the high tightness and high insulation determine a potential risk of poor indoor air quality and condensation at the surfaces; for this reason an efficient ventilation system is necessary to provide for fresh air in the rooms. In a low polluted building air quality depends on human bioeffluents, among which carbon dioxide is considered the most significant one. By using numerical simulations (CFD) the effects of the supply and extract air terminals on contaminants distribution in offices equipped with a cooled ceiling has been investigated. Besides, in order to fully characterize the indoor climate of residential rooms or offices, an extensive experimental study has been carried out in a test room to determine both thermal comfort and ventilation effectiveness for different solutions of mixing ventilation and displacement ventilation combined with floor radiant systems. In particular, the effects of supply and extract air terminals positions by using low air change rates in mixing ventilation and the effects of different ventilation rates with displacement ventilations terminals have been analyzed. Results from experiments have been used for the validation of a CFD model for the prediction of air distribution in rooms equipped with mixed or displacement ventilation, combined with heating/cooling floor systems. In questo lavoro di dottorato vengono presentati i risultati di uno studio sui sistemi radianti per il raffrescamento ed il riscaldamento in ambito civile e sulla loro integrazione con opportuni sistemi di ventilazione meccanica. Le prestazioni energetiche in regime stazionario e transitorio, così come le prestazioni di comfort termico e di qualità dell’aria garantita, sono state studiate mediante l’ausilio di prove sperimentali, di simulazioni fluidodinamiche e di altri codici di calcolo. Gli studi sperimentali sono stati realizzati in parte in Italia, presso i laboratori dell’azienda RHOSS S.p.A di Codroipo (Udine), e in parte presso i laboratori dell’ICIEE (International Centre for Indoor Environment and Energy), dell’Università Tecnica di Danimarca, (DTU) a Lyngby (DK). L’aspetto più rilevante di questo lavoro è legato alla sempre maggiore diffusione dei sistemi radianti come soluzione per il riscaldamento ed il raffrescamento di ambienti interni, in quanto combinano vantaggi energetici ad elevati livelli di comfort termico. Per ragioni dovute alla piccola differenza di temperatura tra l’ambiente e il fluido termovettore, i sistemi radianti si interfacciano molto bene con caldaie a condensazione, pompe di calore, sistemi free cooling, collettori solari e altre sorgenti rinnovabili e soluzioni ad alta efficienza energetica. Il calcolo della resa termica di tali sistemi viene eseguito mediante le equazioni valide per la convezione in regime stazionario, come quelle fornite dalle norme Europee EN 1264 ed EN 15377. In letteratura esistono numerose correlazioni valide per il calcolo della potenza convettiva di superfici orizzontali e verticali e di superfici interne di stanze reali; le norme EN 1264 ed EN 15377 consigliano correlazioni diverse e lo stesso accade per codici si simulazione energetica degli edifici. Ad oggi non è disponibile una chiara definizione di coefficiente di scambio termico convettivo per i sistemi radianti, specialmente per quanto riguarda pavimenti freddi e soffitti caldi. Il primo obiettivo di questa tesi è stato di realizzare un’analisi critica delle correlazioni disponibili in letteratura adatte ai sistemi radianti e di proporre delle equazioni per ogni configurazione di riscaldamento o raffrescamento da soffitto, pavimento o parete. In ambito residenziale il pavimento radiante rappresenta una delle soluzioni più richieste grazie all’elevato livello di comfort termico garantito; tuttavia, al fine di migliorare la qualità dell’aria e specialmente a causa della necessità di deumidificare l’aria in estate per evitare formazione di condensa, accanto al sistema radiante andrebbe installato un sistema di ventilazione meccanica. L’aria primaria in estate è solitamente a temperatura più bassa della temperatura della stanza e dotata di una certa velocità; nel caso di immissione da bocchette installate vicino ad una superficie radiante, lo scambio convettivo potrebbe venire variato rispetto ad una soluzione senza ventilazione. Mediante uno studio con simulazioni fluidodinamiche CFD è stato possibile valutare l’incremento dello scambio convettivo da un soffitto freddo mediante lo sfruttamento di aria primaria. I sistemi radianti, in particolare i sistemi a soffitto, rappresentano un’ottima soluzione per rimuovere i carichi termici degli uffici durante il periodo estivo, ma allo stesso tempo possono essere usati per il riscaldamento invernale degli stessi con buone prestazioni energetiche e di comfort termico. La differenza sostanziale è che durante la stagione invernale il sistema radiante si trova a lavorare prevalentemente in regime stazionario, mentre durante la stagione estiva i carichi esterni dovuti alla radiazione solare e all’escursione diurna, accompagnati da carichi interni dovuti all’occupazione umana, determinano condizioni piuttosto variabili durante la giornata. Il comportamento di sistemi radianti a regimi stazionari e transitori sono state studiate mediante prove in camera climatica; inoltre un modello di calcolo chiamato Digithon, sviluppato all’interno del Dipartimento di Fisica Tecnica dell’Università di Padova, è stato validato mediante un confronto con dati sperimentali. Seguendo un’opportuna procedura, riportata nella tesi, è stato possibile impostare dei profili di carico che simulano una tipica giornata estiva o invernale su una parete della stanza ed è stato studiato come il soffitto radiante reagisca per cercare di mantenere una certa temperatura di comfort nella stanza. Al fine di mantenere una buona qualità dell’aria, evitare la formazione di condensa, ma anche per incrementare la capacità di raffrescamento quando richiesto, i sistemi radianti per gli uffici andrebbero sempre associati a sistemi di ventilazione meccanica. Accanto ai tradizionali sistemi a soffitto con ventilazione a miscelazione, le soluzioni con ventilazione a dislocamento accoppiate a sistemi a pavimento o a soffitto sono alternative di crescente interesse per gli uffici. In edifici dove sia bassa la quantità di inquinanti emessi dai materiali edili, dai mobili e dalle attrezzature, la quantità di bioeffluenti dagli occupanti, dei quali l’anidride carbonica CO2 è normalmente usata come principale indicatore, è determinante per la qualità dell’aria interna. La capacità di rimozione dei contaminanti e, parallelamente, la capacità di immettere aria pulita negli ambienti sono espresse dall’efficienza di ventilazione (ventilation effectiveness). Mediante simulazione fluidodinamiche CFD è stato possibile confrontare l’efficienza di rimozione dei contaminanti utilizzando diverse soluzioni di ventilazione a dislocamento piuttosto che soluzioni tradizionali a miscelazione. La qualità di un ambiente interno andrebbe misurata in termini sia di comfort termico garantito all’occupante che di qualità dell’aria. Attraverso prove sperimentali in laboratorio, i principali indici di comfort termico e di efficienza di ventilazione sono stati determinati per diverse configurazioni di ventilazione a miscelazione e di ventilazione a dislocamento in ambienti rappresentativi di applicazioni residenziali o del terziario. I risultati sono stati in seguito utilizzati per effettuare una validazione di un modello fluidodinamico (CFD) creato per la previsione del movimento dell’aria in ambienti residenziali o uffici.

Abstract:

Thesis (MScEng)--University of Stellenbosch, 2011. ENGLISH ABSTRACT: The perceived quality of Voice over Internet Protocol (IP) (VoIP) communication relies on the network which is used to transport voice packets between the end points. Variable network characteristics such as bandwidth, delay and loss are critical for real-time voice traffic and are not always guaranteed by networks. It is important for network service providers to determine the Quality of Service (QoS) it provides to its customers. The solution proposed here is to predict the perceived quality of a VoIP call, in real-time by using network statistics. The main objective of this thesis is to develop a network analysis tool, which gathers meaningful statistics from network traffic. These statistics will then be used for predicting the perceived quality of a VoIP call. This study includes the investigation and deployment of two main components. Firstly, to determine call quality, it is necessary to extract the voice streams from captured network traffic. The extracted sound files can then be analysed by various VoIP quality models to determine the perceived quality of a VoIP call. The second component is the analysis of network characteristics. Loss, delay and jitter are all known to influence perceived call quality. These characteristics are, therefore, determined from the captured network traffic and compared with the call quality. Using the statistics obtained by the repeated comparison of the call quality and network characteristics, a network specific algorithm is generated. This Non-Intrusive Quality Prediction Algorithm (NIQPA) uses basic characteristics such as time of day, delay, loss and jitter to predict the quality of a real-time VoIP call quickly in a non-intrusive way. The realised algorithm for each network will differ, because every network is different. Prediction results can then be used to adapt either the network (more bandwidth, packet prioritising) or the voice stream (error correction, change VoIP codecs) to assure QoS. AFRIKAANSE OPSOMMING: Die kwaliteit van spraak oor die internet (VoIP) kommunikasie is afhanklik van die netwerk wat gebruik word om spraakpakkies te vervoer tussen die eindpunte. Netwerk eienskappe soos bandwydte, vertraging en verlies is krities vir intydse spraakverkeer en kan nie altyd gewaarborg word deur netwerkverskaffers nie. Dit is belangrik vir die netwerk diensverskaffers om die vereiste gehalte van diens (QoS) te verskaf aan hul kliënte. Die oplossing wat hier voorgestel word is om die kwaliteit van ’n VoIP oproep intyds te voorspel, deur middel van die netwerkstatistieke. Die belangrikste doel van hierdie projek is om ’n netwerk analise-instrument te ontwikkel. Die instrument versamel betekenisvolle statistiek deur van netwerkverkeer gebruik te maak. Hierdie statistiek sal dan gebruik word om te voorspel wat die gehalte van ’n VoIP oproep sal wees vir sekere netwerk toestande. Hierdie studie berus op die ondersoek en implementering van twee belangrike komponente. In die eerste plek, moet oproep kwaliteit bepaal word. Spraakstrome word uit die netwerkverkeer onttrek. Die onttrekte klanklêers kan dan geanaliseer word deur verskeie spraak kwaliteitmodelle om die kwaliteitdegradasie van ’n spesifieke VoIP oproep vas te stel. Die tweede komponent is die analise van netwerkeienskappe. Pakkieverlies, pakkievertraging en bibbereffek is bekend vir hul invloed op VoIP kwaliteit en is waargeneem. Hierdie netwerk eienskappe word dus bepaal uit die netwerkverkeer en daarna vergelyk met die gemete gesprekskwaliteit. Statistiek word verkry deur die herhaalde vergelyking van gesprekkwaliteit en netwerk eienskappe. Uit die statistiek kan ’n algoritme (vir die spesifieke network) gegenereer word om spraakkwaliteit te voorspel. Hierdie Nie-Indringende Kwaliteit Voorspellings-algoritme (NIKVA), gebruik basiese kenmerke, soos die tyd van die dag, pakkie vertraging, pakkie verlies en bibbereffek om die kwaliteit van ’n huidige VoIP oproep te voorspel. Hierdie metode is vinnig, in ’n nie-indringende manier. Die gerealiseerde algoritme vir die verskillende netwerke sal verskil, want elke netwerk is anders. Die voorspelling van spraakgehalte kan dan gebruik word om òf die netwerk aan te pas (meer bandwydte, pakkie prioriteit) òf die spraakstroom aan te pas (foutkorreksie, verander VoIP kodering) om die goeie kwaliteit van ’n VoIP oproep te verseker.

Abstract:

This thesis assesses the appropriateness and effectiveness of discrete event simulation technique to understand and manage service elements in the ISP (Internet Service Provider) context. The baseline for this research involved the secondary data published by ABS (Australian Bureau of Statistics) and TIO (Telecommunications Industry Ombudsman) involving ISP numbers, Internet issues/complaints data. As many relatively new services are being offered, ISPs are finding it difficult to cope with varying customer expectations and their future technology expectancy. Access to infrastructure, avoiding anti—competitive behaviour from large players and service differentiation has become more important than ever for their survival. A number of challenges such as lack of provision of good quality service, lack of ability to cope with increasing (or varying) customer demands and expectations and lack of flexibility in providing services need to be overcome. The service environment in networking has focused heavily on the technical side and very little attention has been given to functional variables such as complaints handling, aligning technical and functional service quality processes and effective service recovery during service failures. Relying fully on the technical side obscures the nature of service. This research identified the fact that end users’ perspective of quality of services need to consider not only the inherent quality of the network, but also the service quality provided by the ISP. Users perceive poor service quality provided by their ISP if they do not get help desk support required from using the ISP services. This can turn a complaint about a problem in to a complaint about the company. The research question is answered by this thesis “What is it that the use of discrete event simulation technique can contribute to the understanding and managing service quality data for different ISP service operations?”The research methodology chosen was discrete event simulation methodology. The discrete event technique involves building up models based on the dynamic behavior of a network system as the time progresses. The appropriateness and effectiveness of this technique was tested by modelling technical service elements (modelling policy based networks using differentiated service schemes, alarm based network management system for effective service level agreement monitoring) and key functional elements that determine ISP non-technical service performance (ISP complaints handling, ISP call centre performance variables). The scenarios led to the development of an integrative simulation framework that addresses both user level service quality issues and network system oriented service quality issues. In the past user level service quality issues have been provided with negligible importance. The framework developed can help ISPs to model service attributes and use the results from such simulation studies to make competitive marketing decisions. The issues raised before and after simulation can be compared for effective service design. To achieve service excellence ISPs have to understand the interrelationship between various service quality dimensions such as tangibles, reliability, responsiveness, assurance and empathy and how these dimensions affect customer perception of ISP service quality. In conclusion the research found that discrete event simulation can be used to understand and manage service quality data by internet service providers involving different ISP service operations.

Abstract:

Background: Food allergy affects an estimated 8% of children and 3% of adults in the United States. Food‐allergic individuals increasingly use the web for medical information. We sought to determine the educational quality of food allergy YouTube videos. Methods: We performed a YouTube search using keywords “food allergy” and “food allergies”. The 300 most viewed videos were included and analyzed for characteristics, source, and content. Source was further classified as healthcare provider, alternative medicine provider, patient, company, media, and professional society. A scoring system (FA‐DQS) was created to evaluate quality (−10 to +34 points). Negative points were assigned for misleading information. Eight reviewers scored each video independently. Results: Three hundred videos were analyzed, with a median of 6351.50 views, 19 likes, and 1 dislike. More video presenters were female (54.3%). The most common type of video source was alternative medicine provider (26.3%). Alternative treatments included the following: water fast, juicing, Ayurveda, apple cider, yoga, visualization, and sea moss. Controversial diagnostics included kinesiology, IgG testing, and pulse test. Almost half of the videos depicted a non‐IgE‐mediated reaction (49.0%).Videos by professional societies had the highest FA‐DQS (7.27). Scores for videos by professional societies were significantly different from other sources (P < .001). There was a high degree of agreement among reviewers (ICC = 0.820; P < .001). Conclusion: YouTube videos on food allergy frequently recommend controversial diagnostics and commonly depict non‐IgE‐mediated reactions. There is a need for high‐quality, evidence‐based, educational videos on food allergy.

Abstract:

Internet of Things gör det möjligt att skapa “smarta miljöer” där information kan utbytas mellan olika typer av enheter. Denna teknik kan leda till effektivisering och automatisering på en mängd olika sätt, till exempel i våra hem och för affärsverksamheter. Ett område där intresset för denna teknik är stort är inom industrin, där området benämns som Industry 4.0. Där förväntas tekniken bland annat kunna användas för att effektivisera och förutse underhåll av maskiner, en inriktning som kallas e-maintenance. Denna nya teknik medför anpassning och utveckling av nya affärsmodeller och olika typer av informationssystem baserade på dessa. För att värde ska kunna skapas för verksamheter vid användande av en informationshanteringsplattform bör värdeskapande faktorer utforskas. Syftet med denna studie är att undersöka, utifrån aspekter ur DeLone och McLeans (2003) Information System Success Model, hur värde kan skapas för ett fallföretag vid användning av en informationshanteringsplattform kopplad till sensorer i verksamheten genom Internet of things. Studien har genomförts med en abduktiv forskningsstrategi och en kvalitativ ansats. En fallstudie har genomförts på ett kundföretag till Sigma Technology, som studien görs i samarbete med. Utifrån ett urval av de anställda på fallföretaget har uppfattningar kring värdeskapande faktorer undersökts, genom enskilda semi- strukturerade intervjuer. Intervjuerna har analyserats och jämförts med Delone och McLeans (2003) Information Systems Success Model för att finna samband eller avvikelser. I studien framkom det att de framstående variablerna för värdeskapande är enkelhet, informationsstruktur, tillgänglighet och pålitlighet. Dessa faktorer ansåg respondenterna vara särskilt viktiga vid utformning av en informationshanteringsplattform. Resultatet visar även att studien till stor del stämmer överens med det teoretiska ramverket och de beroendeförhållanden Information System Success Model presenterar. Faktorer som respondenterna inte ansåg vara lika betydande för värdeskapande och som därmed avvek från modellen är dimensionen servicekvalitet. Baserat på studiens resultat presenteras förslaget att vidareutveckla modellen med den nya dimensionen interaktionskvalité, eftersom att analysen av de värdeskapande faktorerna beskriver detta behov. Internet of Things enables the creation of “smart environments”, where it is possible to exchange information between objects. This can lead to increased efficiency and automatization in different ways, for example in our homes and for business operations. An area where the interest for this technology is immense is in the industrial sector, and is referred to as Industry 4.0. For this area, the adoption of this technology is expected to, for example, improve efficiency and to predict maintenance, an approach known as e-maintenance. This new technology implies modification and development of business models and enables different types of information systems based on these. To be able to generate value for businesses when using an information management platform, variables that create value should be investigated. The purpose of this study is to examine value-adding variables, with aspects from Delone & McLean’s Information System Success Model (2003), for a specific business case by using an information management platform through Internet of Things and sensors in their operations. This study has been carried out as a case study with one of Sigma Technology’s clients, which this study was made in collaboration with. This study was carried out with an abductive research approach and a qualitative method. To examine the opinions of the company’s employees, individual, semi-structured interview was conducted. The interviews was analyzed and compared with Delone & McLean's Information Systems Success Model, to identify resemblance or divergence. The findings in this study show that the significant variables for value to be created are simplicity, information structure, accessibility and reliability. These factors are considered to be especially important, according to the respondents. Findings also show that the study is mostly consistent with the theoretical model, however, some variance has been discovered and some modifications of the model are presented. A dimension that the respondents did not consider equally important for value creation, and thus deviated from the theoretical framework, is service quality. Based on the significant factors presented in the study, the proposal is to further develop the model by adding an additional dimension, interaction quality, for the reason that the analysis of the value creating factors in this study describes this need.

Thesis (MPhil)--Stellenbosch University, 2004. ENGLISH ABSTRACT: The Education Management Information System (EMIS) is the business unit that is responsible for information management and business reporting in the Department of Education. EMIS finds it difficult to provide high quality information to the Department of Education internally and its stakeholders externally and attributes the reduction of the quality of its education information to factors such as the organisational nature of the South African education system, the lack of information management standards and practices, the low level of information technology skills in EMIS, the existence of a multitude of disparate information systems in the Department of Education and Provincial Education Departments, and the apparent discontinuity in the flow of information from education institution level to the national department and back. Most research in information management confirmed the state of EMIS as being typical of most large organisations whose functioning depends on the quality of their information. The factors that influence information quality in EMIS had been identified as accuracy, timeliness, consistency and relevance of the information. A “quick-fix” to the information problem is not possible but research in information systems management indicates that there are trends in the electronic business arena that may provide an acceptable solution to most of the problems encountered by EMIS. This report investigates the nature of EMIS problems in terms of information management and investigates possible solutions to the problems. The investigation is done within the framework of acknowledged information systems planning process and aligned to the process model of information management. An exposition is given on the theory pertaining to information management, information systems and information systems management to give insight into the particular fields of study and their interdependencies. A section on business intelligence is included since business reporting is the primary function of EMIS. Investigations into information systems development indicate an exponential growth in electronic technology development specifically the Internet and the Web. The information systems plan provides the framework or set of guidelines to determine the information systems solution that will be able to solve their problems. The research report included four stages of the information systems plan framework. The first stage pertains to the identification of minimum information required from the education sector and supporting sectors to provide high quality education information for decision-making and planning. The second stage determines and benchmarks the state of EMIS in terms of information management processes. The third stage investigates the trends in electronic business and specifically electronic information systems applications. Current best practices indicate that a possible solution to information management problems in large organisations is the application of a web-based, electronic, enterprise-wide, integrated information system. AFRIKAANSE OPSOMMING: EMIS as ‘n besigheidseenheid in die nasionale Onderwysdepartement is verantwoordelik vir inligtingsbestuur en verslaggewing. EMIS vind dit moeilik om hoë kwaliteit inligting intern aan die onderwysdepartement en ekstern aan sy rolspelers te verskaf. en skryf die verlaging in die kwaliteit van inligting toe aan faktore soos die organisasiestruktuur van die Suid Afrikaanse onderwysstelsel, die gebrek aan standaarde vir inligtingsbestuur en -praktyke, die lae vlak van inligtingstegnologiekennis van die personeel in EMIS, die bestaan van ‘n magdom van ongelyksoortige inligtingstelsels in die nasionale onderwysdepartement en provinsiale onderwysdepartemente en die sigbare diskontinuïteit in die vloei van inligting vanaf die onderwysinrigtings na die nasionale onderwysdepartement en terug. Die meeste navorsing in inligtingsbestuur bevestig dat die toestand waarin EMIS verkeer tipies is van die meeste groot organisasies wie se funksionering van die kwaliteit van hulle inligting afhang. Die faktore wat ‘n rol speel in die kwaliteit van inligting in EMIS word geïdentifiseer as akkuraatheid, tydigheid, uniformiteit en geldigheid. ‘n Vinnige oplossing vir die inligtingsprobleem is nie moontlik nie maar navorsing in inligtingstelselsbestuur dui aan dat daar tendense in die rigting van elektroniese besigheidarena is wat aanvaarbare oplossings bied vir die meeste van EMIS se probleme. Hierdie verslag ondersoek die aard van EMIS se probleme in terme van inligtingsbestuur en ondersoek moontlike oplossings vir die probleme. Die ondersoek word gedoen binne die raamwerk van ‘n aanvaarde inligtingstelsel-beplanningsproses wat opgestel is om binne die prosesmodel vir inligtingsbestuur te val. ‘n Uiteensetting van die teorie ten opsigte van inligtingsbestuur, inligtingstelsels en inligtingstelselbestuur word gegee ten einde insig oor die betrokke studieterreine en hul interafhanklikheid te gee. ‘n Afdeling oor besigheidsintelligensie word ingesluit aangesien besigheidsverslaggewing die primêre funksie van EMIS is. ‘n Ondersoek na inligtingstelselontwikkeling dui op ‘n eksponensiële groei in die ontwikkeling van die elektroniese tegnologiebedryf en spesifiek die Internet en Web. Die inligtingstelselsplan voorsien die raamwerk of riglyne waarbinne die inligtingstelseloplossing gesoek kan word. Die navorsingsverslag sluit vier fases van die raamwerk van die inligtingstelselsplan in. Die eerste fase het te make met die identifisering van die minimum inligting wat nodig is vir besluitneming en beplanning. Die tweede fase stel die toestand van EMIS ten opsigte van inligtingsbestuur vas. Die derde fase ondersoek die neigings in elektroniese besigheidstransaksies en toepassings. Huidige beste praktyke dui aan dat ‘n moontlike oplossing vir die inligtingsbestuurprobleme van groot organisasies die toepassing van ‘n web-gebaseerde, elektroniese, geïntegreerde inligtingstelsel, wat al die komponente van die onderneming insluit, is.
