Abstract:

RSS is a format for easy information sharing between computers. A RSS-file, also known as a feed or a channel, consist of a list of items. The items are structured with XML-tags and have to be processed in some way before it can be read. RSS¬readers, web-browsers with RSS support and e-mail-clients with RSS support can be used to display the feed.

This thesis is focused to investigate if RSS can be used within an enterprise for internal communication. We look at different computer based communication tools that are available today and compare them with RSS. All the different tools has there advantages as well as disadvantages, we have tried to find out if there is room for one more information channel within an enterprise.

Our study shows that RSS is not suitable as a stand alone solution for internal combination. RSS main strengths lies in mass information that has to be pushed out in one direction.

Abstract:

The web has evolved much through the years. From being a place where author and reader were clearly distinguished, it now invites everyone to take part in the development of both content and technology. Social services are central in what is called Web 2.0. Wikis, blogs and folksonomies are all examples of how the users and their communities are key to the development of services. Collaborative writing, tags and API:s are central. Social services are given an extra dimension through integration. The purpose of this study was to investigate whether it was possible to integrate an encyclopedia with a photosharing service. The issue was whether it was possible to find relevant images to the article they were connected to. The method for examining the issue was to create a service which functions was investigated through user tests. Wickrpedia was created, which is an integration of Wikipedia and Flickr. Wikipedia is an encyclopedia in the shape of a wiki, while Flickr is used to store, organize and share photos. The result shows that the images added someting to the encyclopedia; it became more entertaining and pleasant and the users’ knowledge was increased. The relevance of the images was good. The service can and should be improved. The conclusion is still that the service worked well and was seen as an improvement by the users.


Webben har förändrats mycket de senaste åren. Från att tidigare haft en tydlig uppdelning mellan läsare och författare inbjuds nu alla att delta i utvecklingen av både innehåll och teknik. Sociala tjänster är det centrala i det som benämns Web 2.0. Wikis, bloggar och folksonomies är alla exempel på hur användarna och deras gemenskap är nyckeln till utveckling av tjänster. Kollaborativt skrivande, taggar och API:er är centrala. Sociala tjänster får en ytterligare dimension genom integrering. Denna studies syfte var att utreda hur det gick att integrera ett uppslagsverk med en fotodelningstjänst. Frågan är om det gick att göra på ett sådant sätt att bilderna hade relevans för de artiklar de kopplades till. Metoden för att utreda frågan var att skapa en tjänst vars funktion undersöktes med hjälp av användartester. Wickrpedia skapades, vilket är en intregrering av Wikipedia och Flickr. Wikipedia är en encyklopedi i form av en wiki, medan Flickr används för att förvara, organisera och dela med sig av bilder. Resultatet visar att bilderna tillförde något till uppslagsverket; det blev roligare och trevligare och användarna fick en ökad kunskap. Relevansen hos bilderna var god. Tjänsten har brister, och den går att vidareutveckla. Slutsatsen var ändå att tjänsten fungerade och var en förbättring för användarna.

Zivkovic, A. (Aleksandar). "Development of autonomous driving using ROS." Master's thesis, University of Oulu, 2018. http://urn.fi/URN:NBN:fi:oulu-201806062488.

Full text
Abstract:
Autonomous driving, or self-driving, is the ability of a vehicle to drive itself without human input. To achieve this, the vehicle uses mechanical and electronic parts, sensors, actuators and an on-board computer. The on-board computer runs sophisticated software which allows the vehicle to perceive and understand its environment based on sensor input, localise itself in that environment and plan the optimal route from point A to point B. Autonomous driving is no longer a thing of the future, and to develop autonomous driving solutions is a highly valuable skill in today’s software engineering field. Robot Operating System (ROS) is a meta-operating system that simplifies the process of robotics programming. This master’s thesis aims to demonstrate how ROS could be used to develop autonomous driving software by analysing autonomous driving problems, examining existing solutions and developing a prototype vehicle using ROS. This thesis provides an overview of autonomous driving and usage of ROS in the development of autonomous driving, then elaborates on the benefits and challenges of using ROS for autonomous car development. The research methods used in this master’s thesis are design science research (DSR) and a literature review. An artefact is developed and evaluated—a remote-controlled (RC) car equipped with Raspberry Pi 3 board as the on-board computer, an Arduino Uno board, Teensy LC board, a set of sensors and ROS-based software. The thesis is supported by the author’s employer, automotive software company called Elektrobit. By following the steps described in this thesis, it is possible to develop an autonomous driving RC car which runs on ROS. Additionally, this thesis shows why ROS provides good solutions for the autonomous driving issues. It points to the benefits of ROS: open sourced, peer-to-peer, network-based meta-operating system with ready-made components for autonomous driving, and highlights some of the challenges of ROS: security issues and single point of failure.

Papanikolaou, Alexandros. "A combined approach for hiding partial information in RSA." Thesis, Aston University, 2006. http://publications.aston.ac.uk/10680/.

Full text
Abstract:
Partial information leakage in deterministic public-key cryptosystems refers to a problem that arises when information about either the plaintext or the key is leaked in subtle ways. Quite a common case is where there are a small number of possible messages that may be sent. An attacker may be able to crack the scheme simply by enumerating all the possible ciphertexts. Two methods are proposed for facing the partial information leakage problem in RSA that incorporate a random element into the encrypted message to increase the number of possible ciphertexts. The resulting scheme is, effectively, an RSA-like cryptosystem which exhibits probabilistic encryption. The first method involves encrypting several similar messages with RSA and then using the Quadratic Residuosity Problem (QRP) to mark the intended one. In this way, an adversary who has correctly guessed two or more of the ciphertexts is still in doubt about which message is the intended one. The cryptographic strength of the combined system is equal to the computational difficulty of factorising a large integer; ideally, this should be feasible. The second scheme uses error-correcting codes for accommodating the random component. The plaintext is processed with an error-correcting code and deliberately corrupted before encryption. The introduced corruption lies within the error-correcting ability of the code, so as to enable the recovery of the original message. The random corruption offers a vast number of possible ciphertexts corresponding to a given plaintext; hence an attacker cannot deduce any useful information from it. The proposed systems are compared to other cryptosystems sharing similar characteristics, in terms of execution time and ciphertext size, so as to determine their practical utility. Finally, parameters which determine the characteristics of the proposed schemes are also examined.

Encryption has been used for a long time and is used nowadays to encode information in such a way that authorized people will only be able to read it. Encryption is also used for authentication, to hide a person’s identity. The goal with this thesis is to create an encryption program which will be able to perform encryption and decryption with two algorithms. There are already a number of encryption programs on market and we hope that our program will be as good as these. Performance tests will be done after the program is finished to see if the goals have been achieved. This thesis is done together with the help from Forsvarsmakten. This thesis is written in Swedish.

Abstract:
Introduction: As Information Technology (IT) becomes more and more advanced, the Enterprise System (ES) starts to attract researcher’s attention. While with the high rate of failure IT projects, it is important to evaluate the IT project properly. This paper conducts a case study in the Health Care area and chooses Jönköping County Council’s ROS system to be the target system. According to the established linkage between theory and real world organization, a practice of Enterprise System Evaluation is conducted by using an existing Uwizeyemungu et al.’s Enterprise System Effects Evaluation Model (ESEM). The research questions are as follows: What are the Enterprise Systems Effects which impact on business processes? To what extend do the ES effects impact on the business processes? Purpose: the study is an exploratory study that aims at identifying what are the ES Effects which impact on the business processes and assessing the importance and the actual degree of these effects. The answers of the first goal are explored by analyzing the documents and the record of interview, and the results are the basis of the second question. Method: This research has adopted a combined approach because of the nature of the research questions. Data has been collected through face-to-face interview, survey and the organizational documents. Secondary data are also be used for analyzing. Both qualitative and quantitative data are used for getting a reliable conclusion. Conclusions: The Enterprise System effects can be categorized into automaional effects, informational effects and transformational effects. The relationship between such effects and Performance indicators are very important. By determining the importance and impacts degree of such relationships, the evaluation results can be explicitly calculated and understood.

Abstract:
The Rich Communication Service (RCS) aims to be the default messaging protocol in mobile devices. The native integration of RCS opens up the possibility of RCS chatbots replacing single-purpose apps. This report analyzes this possibility through in-depth experimentation of the chatbot functionality, followed by user testing of the chatbot features. The report found that the RCS chatbot could replace mobile applications since many solve a specific task and follow a closed-loop system. The report also identified RCS as a solution to the accumulated unused apps users have on their mobile devices. This report also attempts to fill the research gap on the current situation of RCS and the reasons behind the different rollout rates of RCS globally. The examination of interviews with RCS stakeholders was the basis of a stakeholder analysis. This analysis found that the Mobile Network Operators have different standings regarding RCS. Some see potential, and some see issues with RCS hindering the global rollout. Furthermore, the reluctance from Apple and the high involvement of Google are reviewed and contrasted with the answers from the interviews.
Rich Communication Service (RCS) siktar på att bli det nya standardprotokollet för att skicka meddelanden mellan mobiler. RCS potentiella integration i mobilens egna meddelande applikation öppnar upp för möjligheten att RCS- chatbotar även kan ersätta enklare appar med begränsade användningsområden. Denna rapport undersöker den här möjligheten genom experimenterande med chatbotens funktionalitet följt av användartester på chatbotens olika funktioner. Rapporten fann att chatboten i RCS har goda möjligheter att ersätta enklare mobila applikationer då många löser specifika uppgifter som följer ett system med en sluten slinga. Rapporten identifierade även RCS som en lösning till den mängd oanvända appar som användare har i sina mobiler. Denna rapport försöker även fylla det forskningsgap som finns angående RCS nuvarande situation och anledningarna till de olika adoptionshastigheterna i världen. Granskning av de intervjuer som hölls med olika intressenter på marknaden blev grunden för den intressentanalys som presenteras. Denna analys visade att teleoperatörer har olika ställningar gentemot RCS. Vissa ser potential medan andra främst ser problem vilket hindrar spridningen av RCS. Dessutom analyserades Apples ovilja att anamma RCS samt Googles

Abstract:
Abstract Since the collapse of the Soviet Union Russia has undergone a number of reforms towards developing market economy. Accounting has encountered dramatic changes over the last two decades. Despite attractive investment opportunities in Russia, investors are often faced with uncertainty, which makes it very important to explore the quality of accounting information published in Russia. The purpose of this thesis is to investigate the quality of published accounting information in Russia. The thesis consists of four essays, each of them addressing the question of the quality of accounting information published in Russia by incorporating the specific Russian institutional environment. Special attention is paid to the role of International Financial Accounting Standards (IFRS) and foreign investors. The quality of published accounting information is conceptualized by such accounting constructs as conservatism, earnings management and value relevance. This first essay investigates the earnings quality of both listed and non-listed Russian firms and explores whether foreign ownership affects the quality of earnings published by non-listed Russian firms. The second essay examines whether emphasis on international investors is associated with the adoption of or intention to adopt IFRS in Russian firms. The third essay addresses the question of IFRS and Russian Accounting Standards (RAS) accounting quality by using the methodology proposed by Barth et al. (2008) and by value relevance constructs of accounting quality. The fourth essay investigates the value relevance of firms’ integral environmental impact, i.e. a proxy for environmental performance, following the stream of non-financial information value relevance in accounting research. This thesis provides evidence that the quality of published accounting information published in Russia depends on many factors, the most influential of these being listing on the stock exchange, IFRS and foreign investors. The results of the thesis demonstrate that the institutional characteristics of the country shape accounting numbers and influence the incentives of those preparing financial statements. The findings of the thesis include information valuable for regulators and investors.

In this paper, doubling in Russian Sign Language and Sign Language of the Netherlands is discussed. In both sign languages different constituents (including verbs, nouns, adjectives, adverbs, and whole clauses) can be doubled. It is shown that doubling in both languages has common functions and exhibits a similar structure, despite some differences. On this basis, a unified pragmatic explanation for many doubling phenomena on both the discourse and the clause-internal levels is provided, namely that the main function of doubling both in RSL and NGT is foregrounding of the doubled information.

Abstract:
Lo sviluppo hardware nel campo della robotica ha raggiunto negli ultimi anni livelli impressionanti ed è in continua crescita, e di pari passo si è espansa l’eterogeneità delle forme che può assumere, dalle tipologie basate su movimento a terra ai droni volanti, fino a forme più sofisticate di robot umanoidi che cercano di emularne il comportamento. Se da un lato ora possiamo disporre di hardware sempre più potente ed efficiente a costi sempre minori, dall’altro programmare il comportamento che un robot deve tenere nelle svariate circostanze in cui può imbattersi, nel poter portare a compimento il proprio obbiettivo, risulta essere sempre più complesso. Dopo una breve introduzione alla robotica e alle difficoltà che deve affrontare e una panoramica sui robot, cosa siano e come siano strutturati, fulcro della tesi sarà l’esposizione delle caratteristiche principali di ROS, Robot Operating System, come piattaforma di sviluppo software nel campo della robotica, e si concluderà con un semplice caso di studio in cui ne verrà messo in mostra concretamente l’utilizzo.

ENGLISH ABSTRACT: Traditional top-down decision-making models have become unpopular since public institutions have been demanding more democracy at local level. New approaches and techniques have focused on how the majority of people can be involved in a bottom-up approach to development and decision making. Techniques, such as Participatory Rural Appraisals (PRAs), have identified people's concerns regarding the use of natural resources centred on land issues. Land is essentially a subject of public concern. Land as a spatial phenomenon controlled politically and used by all for survival and other purposes needs to be assessed in an integrated and time-spatial way for better planning and decision making. Geographical Information Systems (GISs) have often been used by statutory "experts" in evaluating, analysing and mapping of land and land-related features. GISs have a lot of potential in being applied as decision-making tools. If this is the case, how can public perceptions and politics be presented and mapped in a GIS to improve and democratise decision making even further? The study has investigated new methods of representing people's perspectives at grassroots level in a non-traditional way. A sub-region of the Lowveld, situated in the Mpumalanga province, has been selected because of the various kinds of land owners in the region. The Kruger National Park lies to the east of the study area, from where some black communities claim to have been removed. To the west of that is one of the districts of the former homeland KaNgwane, namely Nsikazi, and west of that two areas of intensive large-scale commercial fruit and vegetable production in the Nelspruit-White River and Kiepersol-Hazyview areas. Towards the escarpment north-west of these lie large commercial exotic forest plantations, owned mainly by Safcol and MandL Given the high demand and need for land from the overpopulated Nsikazi district, the process of land reform is a matter of great concern. White male commercial farmers in both regions where commercial farming is active were interviewed about their knowledge and perceptions of land reform. Various themes were presented to the farmers to comment on, namely the history of forced removals, land use, land potential, hydrology and where land reform should take place. Interviews were taped in Afrikaans, transcribed and translated to English. "Mental maps" were drawn on tracing paper overlaid on topographical maps of the Land Surveyor General, Mowbray. These were digitised and managed in Arclnfo, and displayed and analysed in ArcView, from where output maps were produced. The results of this technique proved to be very useful and can certainly broaden the use of GISs in decision making and public participation. However, GISs alone cannot be seen as the solution to better development and better decision-making. Public participation is of the utmost value in facilitating and initiating these processes. Land use planning needs to be the responsibility and concern of all land users and owners at a local level, where GISs can be applied as a tool to provide easier and more effective analysis and results for the implementation of initiatives.
AFRIKAANSE OPSOMMING: Tradisionele bo-na-onder besluitnemingsmodelle het in die laaste paar dekades baie ongewild geraak met die totstandkoming van instellings wat die publiek se mening hoog ag en demokrasie op grondvlak probeer bevorder. Nuwe benaderings en tegnieke poog nou om die publiek se mening in 'n onder-na-bo benadering tot ontwikkeling en besluitneming te integreer. Grondhervorming is basies die erns van die publiek, meer so as die staat. Grond is 'n ruimtelike verskynsel wat polities beheer word maar deur die meerderheid gebruik word vir oorlewing asook ander doeleindes. Dit behoort op 'n tyd-ruimtelike basis op 'n geïntegreerde wyse vir beter beplanning en besluitneming ondersoek te word. Geografiese Inligtingstelsels (GISs) word hoofsaaklik deur statutêre "kenners" gebruik in die evaluering, analise en kartering van grond en verbandhoudende verskynsels. Dit beskik verder oor die potensiaal om in besluitnemingsprosesse gebruik te word. Die vraag ontstaan egter hoe die publiek se menings en politieke strukture met 'n GIS verteenwoordig en gekarteer kan word ter verbetering van besluitneming op 'n meer demokratiese wyse. Die studie het nuwe metodes ondersoek waarvolgens mense op grondvlak se persepsies op nie-tradisionele maniere verteenwoordig en ondersoek kan word. 'n Sub-streek van die Laeveld wat geleë is in die Mpumalanga provinsie, is geselekteer vanweë die verskeidenheid grondeienaars wat daar voorkom. Die Kruger Nasionale Park is geleë in die oostelike deel van die studiegebied vanwaar sekere swart gemeenskappe gedurende die Apartheidsregime verskuif is. Direk wes hiervan lê die voormalige tuisland KaNgwane se Nsikazi distrik en wes daarvan twee areas, naamlik Nelspruit-Witrivier en Kiepersol-Hazyview, waar die kommersiële boerdery van vrugte en groente op groot skaal beoefen word. In die noordwestelike gedeeltes van die studiegebied kom grootskaalse uitheemse bosbouplantasies voor wat aan Safcol en Mondi behoort. Met die stygende aanvraag na grond vir residensiële- en landbougebruik in die streek, veral vanuit die Nsikazi distrik, is grondhervorming en die toepassing daarvan, 'n probleem, indien nie 'n bedreiging, vir die meeste grondeienaars. Onderhoude is met blanke manlike kommersiële boere, in albei die kommersiële streke gevoer om hul menings en kennis van grondhervorming te ondersoek. Verskeie temas is as besprekingspunte gestel, naamlik die geskiedenis van gedwonge verskuiwings, grondgebruik, grondpotensiaal, water hulpbronne en waar hul meen grondhervorming sou moes plaasvind. Onderhoude was in Afrikaans opgeneem, getranskribeer en in Engels vertaal. "Kognitiewe kaarte" was op deursigtige papier geteken wat oor 'n reeks topografiese kaarte van die gebied gelê is. Die resultate is versyfer en in Arelnfo gemanipuleer en daarna in ArcView ontleed en vir verslaglewering gekarteer. Die resultate van die tegniek beloof om vir beide besluitnemers en die publiek as deelnemers in die proses baie bruikbaar te wees. Dit verbreed ook die gebruik en toepassing van GISs en die sisteem se vermoëns. GISs kan egter nie alleenlik aangewend word om ontwikkeling en besluitneming vir die publiek beter of meer aanvaarbaar te maak nie. Alle mense se deelname is van die uiterste belang en waarde in die inisiëring, fasilitering en implementering van strategieë en projekte. Grondgebruiksbeplanning moet die verantwoordelikheid van almal word wat grond op plaaslike vlak gebruik of besit, nie net van die wat deur 'n probleem of program, soos grondhervorming, geraak word nie. 'n GIS kan aangewend word om die prosesse van ontwikkeling en besluitneming te vergemaklik deur analises vinniger en op 'n meer effektiewe manier te ondersoek vir beter en meer demokratiese besluitneming.

Abstract:
Lo studio effettuato raccoglie informazioni al fine di svolgere un’analisi globale delle tecniche attualmente in uso, o in fase di studio, nel campo della localizzazione di dispositivi all’interno di un ambiente chiuso, ovvero laddove non è possibile sfruttare la copertura del sistema GPS. La panoramica è frutto dell’analisi e dello studio di paper tecnici pubblicati dai collaboratori dell’IEEE, fruibili all’interno del portale IEEE Xplore. A corredo di questo studio è stata sviluppata una applicazione per dispositivi Android basata sulla tecnica del Wi-Fi fingerprint; l’applicazione, che rappresenta un primo approccio alle tecniche di localizzazione, è a tutti gli effetti un sistema standalone per la localizzazione, consente cioè di costruire sia la mappa per la localizzazione, partendo da un ambiente sconosciuto, sia di ottenere la posizione dell’utente all’interno di una mappa conosciuta. La tesi si conclude con una analisi dei risultati e delle performance ottenute dall’applicazione in un uso comune, al fine di poter valutare l’efficacia della tecnica presa in considerazione. I possibili sviluppi futuri sono analizzati in un capitolo a parte e trovano spazio in ambienti nei quali si vogliono offrire servizi "context-based", ovvero basati sulla posizione esatta dell’utente.

Abstract:
Questa tesi ha come scopo principale l'analisi delle diverse tecnologie di localizzazione in ambito indoor, analizzando in particolare l'utilizzo del Wifi RSS Fingerprinting. La tecnica del Wifi RSS Fingerprinting è una tecnica per la localizzazione all'interno di ambienti chiusi, che consiste nella definizione di un 'impronta'(fingerprint) in un punto preciso dell'ambiente(definito reference point), andando a inserire in un database i valori di potenza del segnale ricevuto(RSS) da ogni access point rilevato all'interno di quel determinato reference point. Per l'implementazione di questa tecnica è stato sviluppato un applicativo con un architettura client-server. Il client è stato sviluppato in ambiente Android, realizzando una applicazione per la gestione della fase di salvataggio di nuovi fingerprint e per la fase di localizzazione della posizione corrente, tramite l'utilizzo dei vari fingerprint precedentemente inseriti all'interno del DB. Il server, sviluppato in Node.js(framework Javascript), gestirà le diverse richieste ricevute dal client tramite delle chiamate AJAX, prelevando le informazioni richieste direttamente dal database. All'interno delle applicativo sono stati implementati diversi algoritmi per la localizzazione indoor, in modo da poter verificare l'applicabilità di questo sistema in un ambito reale. Questi algoritmi sono stati in seguito testati per valutare l'accuratezza e la precisione di ciascuno, andando ad individuare gli algoritmi migliori da utilizzare in base a scenari diversi.

I Sistemi Informativi sono oggi il mezzo più importante di gestione in ambito sanitario in quanto consentono di creare flussi continui, veloci e sicuri di dati essenziali lungo tutto il workflow ospedaliero. Il presente lavoro di tesi si propone di analizzare in particolare gli attuali Sistemi Informativi di Radiologia. La complessa gestione del workflow radiologico è significativamente alleggerita dall’efficiente impiego di due sistemi: il RIS e il PACS. La completa integrazione tra questi due sistemi consente di seguire digitalmente ogni passo del paziente nel flusso radiologico, facilitando e velocizzando l’intero processo. A supporto dell’analisi viene proposto e approfondito un caso di studio riguardante la reale implementazione pratica di tali sistemi presso l’Istituto Ortopedico Rizzoli.

Abstract:

The company Roxen Internet Software have an implementation of the secure network protocol SSL (Secure Sockets Layer) which is used in their web server product. This report describes the upgrading of that implementation to the TLS1.0 (Transport Layer Security) standard. It also describes a performance investigation of the SSL/TLS support in the Roxen WebServer and compares it with other common web servers. The initial setup time for the secure SSL/TLS connection was found to be very long in the Roxen Webserver compared to its competitors. The main bottleneck, in the Roxen implementation, was found to be the modular exponentiation that is the core of the RSA decryption algorithm. One suggested improvement is to upgrade the bignumber numerical package used in Roxen WebServer, GMP (The GNU Multiple Precision arithmetic library) from version 2.0 to version 4.0. The newer version of the bignumber package have been measured to have considerably better performance in its modular exponentation operation.

Abstract:
Wireless Sensor Networks (WSNs) have gained significant consideration these days, as opposed to wired sensor networks, by introducing multi-functional wireless nodes, which are smaller in size. The main advan-tage is that its wireless, so it costs less to install, maintain and reconfig-ure. These sensor nodes are used in various application areas. For ex-ample: residential, industrial, environmental and military application areas. However WSNs communication is prone to negative influences from the physical environment, such as physical obstacles and interfer-ence. Algorithms must be developed for handling these problems and also to investigate the channel properties. The purpose of this work is to design a testbed, which enables the communication of wireless sensor nodes, to capture the properties of the channel, which will, in the long run, enable better solutions to be designed which are, more appropriate to the errors in the channel. In this testbed, one channel, from the IEEE 802.15.4 channels spectrum, is dedicated as an emergency channel, which is used for handshaking and to handle channel/external interfer-ence or hardware failure between the communication of Transmitter (TX) and Receiver (RX) nodes. The remaining 15 channels are called data channels and are used for actual data transmission and control signals. Peer to Peer transmission of a transmitter-receiver pair is achieved with the introducing of beacons and acknowledgment (ACK) packets. The testbed also has the property of dual reception and data logging on a single PC by maeans of two RX nodes simultaneously from a single TX node. The dependency of the packet on the “Frame Length” byte(in the Frame header) during the reception is eliminated so that if the “Frame Length” byte is compromised, it will replace the programmer defined value with the “Frame Length” byte which helps to investigate the actual packets byte sent from the TX. Also, the Received Signal Strength (RSS) is calculated at the maximum sample rate of the channel. Power consumption is not considered in this testbed. The work is conducted on both the IEEE 802.15.4 physical and the application layers. Linux based TinyOS-2.x is used as an operating system for low power sensor devices. New algorithms are designed for each step in the development of the testbed. MICAz motes are used as nodes and an MIB520 programming board is used for burning the codes and for the purpose of gateways.

Cette recherche s’intéresse aux stratégies RSE diffusées par les grandes entreprises. A l’issue d’une collecte des rapports annuels et de développement durable des entreprises du CAC40 sur trois années, une analyse de contenu quantitative a été menée afin de tester l’influence potentielle de plusieurs facteurs sur le processus d’adoption et de diffusion des stratégies RSE : l’appartenance au secteur d’activité, l’existence d’une conception française de la RSE, ainsi que le profil du dirigeant. Mis en évidence suite à une revue théorique accompagnée de plusieurs recherches exploratoires, ces facteurs semblent, au regard des résultats obtenus, exercer une influence sur le niveau d’implication adopté ainsi que sur l’orientation thématique des rapports. Plus globalement, ce travail met en évidence les facteurs micro et macroéconomiques susceptibles d’influencer l’implication responsable des entreprises. La méthodologie d’analyse de contenu de type lexicométrique a également permis de développer une grille de lecture des informations issues du reporting durable exigé par l’article 116 de la loi NRE, favorisant la mise en évidence des priorités des textes pour les entreprises et pour leurs parties prenantes
This research focuses on the CSR strategies published by big companies. After collecting annual and sustainable development reports of the CAC40 companies during three years, a quantitative content analysis has been made to test the potential influence of several factors on the adoption and diffusion process of the CSR strategies: the belonging to a business sector, the existence of a French conception of CSR, and the corporate executives’ profiles. Underlined with a literature review and several exploratory works, these factors, considering our results, seem to influence the level of responsible involvement and the thematic content in the reports. All things considered, this work brings to light the micro and macroeconomics factors which can influence the responsible implication of the companies. The methodology of quantitative content analysis also offers the opportunity to develop a model which helps reading the information of sustainable reporting, demanded by the article 116 of the NRE law in France, and permitting to highlight the priorities of the contents published, for the companies and their stakeholders

Hu, Wenbiao. "Applications of Spatio-temporal Analytical Methods in Surveillance of Ross River Virus Disease." Queensland University of Technology, 2005. http://eprints.qut.edu.au/16109/.

Full text
Abstract:
The incidence of many arboviral diseases is largely associated with social and environmental conditions. Ross River virus (RRV) is the most prevalent arboviral disease in Australia. It has long been recognised that the transmission pattern of RRV is sensitive to socio-ecological factors including climate variation, population movement, mosquito-density and vegetation types. This study aimed to assess the relationships between socio-environmental variability and the transmission of RRV using spatio-temporal analytic methods. Computerised data files of daily RRV disease cases and daily climatic variables in Brisbane, Queensland during 1985-2001 were obtained from the Queensland Department of Health and the Australian Bureau of Meteorology, respectively. Available information on other socio-ecological factors was also collected from relevant government agencies as follows: 1) socio-demographic data from the Australia Bureau of Statistics; 2) information on vegetation (littoral wetlands, ephemeral wetlands, open freshwater, riparian vegetation, melaleuca open forests, wet eucalypt, open forests and other bushland) from Brisbane City Council; 3) tidal activities from the Queensland Department of Transport; and 4) mosquito-density from Brisbane City Council. Principal components analysis (PCA) was used as an exploratory technique for discovering spatial and temporal pattern of RRV distribution. The PCA results show that the first principal component accounted for approximately 57% of the information, which contained the four seasonal rates and loaded highest and positively for autumn. K-means cluster analysis indicates that the seasonality of RRV is characterised by three groups with high, medium and low incidence of disease, and it suggests that there are at least three different disease ecologies. The variation in spatio-temporal patterns of RRV indicates a complex ecology that is unlikely to be explained by a single dominant transmission route across these three groupings. Therefore, there is need to explore socio-economic and environmental determinants of RRV disease at the statistical local area (SLA) level. Spatial distribution analysis and multiple negative binomial regression models were employed to identify the socio-economic and environmental determinants of RRV disease at both the city and local (ie, SLA) levels. The results show that RRV activity was primarily concentrated in the northeast, northwest and southeast areas in Brisbane. The negative binomial regression models reveal that RRV incidence for the whole of the Brisbane area was significantly associated with Southern Oscillation Index (SOI) at a lag of 3 months (Relative Risk (RR): 1.12; 95% confidence interval (CI): 1.06 - 1.17), the proportion of people with lower levels of education (RR: 1.02; 95% CI: 1.01 - 1.03), the proportion of labour workers (RR: 0.97; 95% CI: 0.95 - 1.00) and vegetation density (RR: 1.02; 95% CI: 1.00 - 1.04). However, RRV incidence for high risk areas (ie, SLAs with higher incidence of RRV) was significantly associated with mosquito density (RR: 1.01; 95% CI: 1.00 - 1.01), SOI at a lag of 3 months (RR: 1.48; 95% CI: 1.23 - 1.78), human population density (RR: 3.77; 95% CI: 1.35 - 10.51), the proportion of indigenous population (RR: 0.56; 95% CI: 0.37 - 0.87) and the proportion of overseas visitors (RR: 0.57; 95% CI: 0.35 - 0.92). It is acknowledged that some of these risk factors, while statistically significant, are small in magnitude. However, given the high incidence of RRV, they may still be important in practice. The results of this study suggest that the spatial pattern of RRV disease in Brisbane is determined by a combination of ecological, socio-economic and environmental factors. The possibility of developing an epidemic forecasting system for RRV disease was explored using the multivariate Seasonal Auto-regressive Integrated Moving Average (SARIMA) technique. The results of this study suggest that climatic variability, particularly precipitation, may have played a significant role in the transmission of RRV disease in Brisbane. This finding cannot entirely be explained by confounding factors such as other socio-ecological conditions because they have been unlikely to change dramatically on a monthly time scale in this city over the past two decades. SARIMA models show that monthly precipitation at a lag 2 months (=0.004,p=0.031) was statistically significantly associated with RRV disease. It suggests that there may be 50 more cases a year for an increase of 100 mm precipitation on average in Brisbane. The predictive values in the model were generally consistent with actual values (root-mean-square error (RMSE): 1.96). Therefore, this model may have applications as a decision support tool in disease control and risk-management planning programs in Brisbane. The Polynomial distributed lag (PDL) time series regression models were performed to examine the associations between rainfall, mosquito density and the occurrence of RRV after adjusting for season and auto-correlation. The PDL model was used because rainfall and mosquito density can affect not merely RRV occurring in the same month, but in several subsequent months. The rationale for the use of the PDL technique is that it increases the precision of the estimates. We developed an epidemic forecasting model to predict incidence of RRV disease. The results show that 95% and 85% of the variation in the RRV disease was accounted for by the mosquito density and rainfall, respectively. The predictive values in the model were generally consistent with actual values (RMSE: 1.25). The model diagnosis reveals that the residuals were randomly distributed with no significant auto-correlation. The results of this study suggest that PDL models may be better than SARIMA models (R-square increased and RMSE decreased). The findings of this study may facilitate the development of early warning systems for the control and prevention of this widespread disease. Further analyses were conducted using classification trees to identify major mosquito species of Ross River virus (RRV) transmission and explore the threshold of mosquito density for RRV disease in Brisbane, Australia. The results show that Ochlerotatus vigilax (RR: 1.028; 95% CI: 1.001 - 1.057) and Culex annulirostris (RR: 1.013, 95% CI: 1.003 - 1.023) were significantly associated with RRV disease cycles at a lag of 1 month. The presence of RRV was associated with average monthly mosquito density of 72 Ochlerotatus vigilax and 52 Culex annulirostris per light trap. These results may also have applications as a decision support tool in disease control and risk management planning programs. As RRV has significant impact on population health, industry, and tourism, it is important to develop an epidemic forecast system for this disease. The results of this study show the disease surveillance data can be integrated with social, biological and environmental databases. These data can provide additional input into the development of epidemic forecasting models. These attempts may have significant implications in environmental health decision-making and practices, and may help health authorities determine public health priorities more wisely and use resources more effectively and efficiently.

Abstract:
Model Based Systems Engineering (MBSE) approach aims at implementing various processes of Systems Engineering (SE) through diagrams that provide different perspectives of the same underlying system. This approach provides a basis that helps develop a complex system in a systematic manner. Thus, this thesis aims at deriving a system model through this approach for the purpose of autonomous driving, specifically focusing on developing the subsystem responsible for generating a feasible trajectory for a miniature vehicle, called AutoCar, to enable it to move towards a goal. The report provides a background on MBSE and System Modeling Language (SysML) which is used for modelling the system. With this background, an MBSE framework for AutoCar is derived and the overall system design is explained. This report further explains the concepts involved in autonomous trajectory planning followed by an introduction to Robot Operating System (ROS) and its application for trajectory planning of the system. The report concludes with a detailed analysis on the benefits of using this approach for developing a system. It also identifies the shortcomings of applying MBSE to system development. The report closes with a mention on how the given project can be further carried forward to be able to realize it on a physical system.
Modellbaserade systemteknikens (MBSE) inriktning syftar till att implementera de olika processerna i systemteknik (SE) genom diagram som ger olika perspektiv på samma underliggande system. Detta tillvägagångssätt ger en grund som hjälper till att utveckla ett komplext system på ett systematiskt sätt. Sålunda syftar denna avhandling att härleda en systemmodell genom detta tillvägagångssätt för autonom körning, med särskild inriktning på att utveckla delsystemet som är ansvarigt för att generera en genomförbar ban för en miniatyrbil, som kallas AutoCar, för att göra det möjligt att nå målet. Rapporten ger en bakgrund till MBSE and Systemmodelleringsspråk (SysML) som används för modellering av systemet. Med denna bakgrund, MBSE ramverket för AutoCar är härledt och den övergripande systemdesignen förklaras. I denna rapport förklaras vidare begreppen autonom banplanering följd av en introduktion till Robot Operating System (ROS) och dess tillämpning för systemplanering av systemet. Rapporten avslutas med en detaljerad analys av fördelarna med att använda detta tillvägagångssätt för att utveckla ett system. Det identifierar också bristerna för att tillämpa MBSE på systemutveckling. Rapporten stänger med en omtale om hur det givna projektet kan vidarebefordras för att kunna realisera det på ett fysiskt system.

Abstract:
When designing military vehicles, it is of interest to make the vehicles difficult to detect using radar. The radar cross-section (RCS) property indicates how easily a vehicle is detected by radar and should thus be minimized. However, the RCS of a vehicle represents the cross-sectional area of a perfectly reflecting sphere that would produce the same reflection strength as the vehicle in question. Since this is extremely complicated to calculate as military vehicles are quite complex, these calculations are performed using computational simulations. BAE Systems Hägglunds is looking into changing from their current simulation software OPTISCAT to CST Studio Suite and thus want to know how CST performs and compares against OPTISCAT. In this work, we show that CST obtains results within 2% of theoretical data when simulating a sphere and a slab. When simulating vehicles, the RCS difference between the two software is from 3% to 55% while showing similar general behavior. Results indicate that CST performs well when simulating simple objects but deviates from OPTISCAT when simulating the vehicle. It is not surprising that the software does not match up perfectly since they use different theoretical approaches, OPTISCAT uses physical optics while CST an extension to physical optics called the Shooting Bouncing Ray method. Even though the software differs to this extent it is most likely possible that CST can be a suitable replacement for OPTISCAT. When looking at RCS the important part is the location of spikes and since they have similar general behavior, those spikes may still be possible to identify. This thesis will hopefully act as a starting point for further examination of CST as a software for simulating RCS, for example by comparing results from CST to experimentally measured data. Hopefully it will also be used to improve the design process of making military vehicles harder to detect.

Abstract:
Technical indicators are used by experts in stock trading. The purpose of this report is to investigate whether or not some indicators perform better when applied to stocks of specific market sectors. The investigation was conducted by implementing one algorithm for each of three different technical indicators, Relative Strength Index, Moving Average Convergence-Divergence, and Larry Williams %R. Each algorithm considered one trading strategy. Three market sectors defined by the GICS were included in the tests, Consumer Staples, Utilities, Information Technology. For each of these sectors at least one stock from each industry were tested. Results suggest that the performance of the Relative Strength Index indicator may be related to the sector of the stock to which it is applied, while %R showed no such indication, and MACD showed only a slight performance deviation between sectors. Further and more in-depth studies are required to confirm the results and conclusions drawn in this report.

Abstract:
The Environmental Resource Mapping System (E-RMS) is a geographic information system (GIS) that is used by the National Parks and Wildlife Service to assist in management of national parks. The package is available commercially from the Service and is used by other government departments for environmental management. E-RMS has also been present in Australian Universities and used for academic work for a number of years. This thesis demonstrates that existing procedures for product quality and performance have not been followed in the production of the package and that the package and therefore much of the work undertaken with the package is fundamentally flawed. The E-RMS software contains and produces a number of serious mistakes. Several problems are identified and discussed in this thesis. As a result of the shortcomings, the author recommends that an enquiry be conducted to investigate *1/ The technical feasibility of each project for which the E-RMS package has been used; *2/ The full extent and consequences of the failings inherent with the package; and *3/ The suitability of the E-RMS GIS package for the purposes for which it is sold. Australian Standard 3898 requires that the purpose, functions and limitations of consumer software shall be described. To comply with this standard, users of the E-RMS package would have to be informed of several factors related to it. These are discussed in the research. Failure to consider the usefulness and extractable nature of information in any GIS database will inevitably lead to problems that may endanger the phenomena that the GIS is designed to protect.

Abstract:
We live in an age where we willingly provide our social security number, credit card information, home address and countless other sensitive information over the Internet. Whether you are buying a phone case from Amazon, sending in an on-line job application, or logging into your on-line bank account, you trust that the sensitive data you enter is secure. As our technology and computing power become more sophisticated, so do the tools used by potential hackers to our information. In this paper, the underlying mathematics within ciphers will be looked at to understand the security of modern ciphers. An extremely important algorithm in today's practice is the Advanced Encryption Standard (AES), which is used by our very own National Security Agency (NSA) for data up to TOP SECRET. Another frequently used cipher is the RSA cryptosystem. Its security is based on the concept of prime factorization, and the fact that it is a hard problem to prime factorize huge numbers, numbers on the scale of 2^{2048} or larger. Cryptanalysis, the study of breaking ciphers, will also be studied in this paper. Understanding effective attacks leads to understanding the construction of these very secure ciphers.

Abstract:
Spatial Decision Making as a branch of decision making science deals with geographically related data in order to achieve complex spatial decision problems. Fuzzy set theory is one of the methods that can be used to come up with these types of problems. On the other hand, Geographical Information Systems (GIS) is one of the most powerful tools that we can use to accomplish spatial decision problems. Selection of the suitable site or land-use for the real estate is also a spatial decision making problem. When we consider the initial dynamics of the suitably located property from the point of view of value and potential we observe that the &ldquo
good location&rdquo
is the dominating factor. This study reports on the development of a kind of decision support system for locational suitability of settlements that integrates the fuzzy set (FZ) theory, a rule-based system (RBS) and GIS. This study is thought as the assistant for the property managers that are buyers and sellers. It can function as the property consultant for the buyers when they are looking for a property to buy and also it helps the real estate agencies to sell their properties. On the other hand, different scenarios of the potential areas according to the different user&rsquo
s preferences are depicted and they are joined and compared with the results of the vulnerability to earthquake hazards&rsquo
of the same area. Odunpazari - Eskisehir area is selected for implementation of the case study because of the data availability. As a result of this study, it can be said that most suitable property changes depending on the people&rsquo
s preferences. In addition, it is seen that most of the buildings that are locationally suitable are highly vulnerable to the earthquake hazards.

Abstract:
Since the damming and channelization of the lower Long Tom River in the 1940s and 1950s, the quality and quantity of habitat for coastal cutthroat trout and spring Chinook salmon in the watershed has dramatically diminished. In order to better understand the potential for stream restoration, this study uses 2D hydraulic modeling to determine the impact of reconnecting historical meander bends to the main stem of the lower Long Tom River on localized flooding, sediment erosion and deposition, and salmonid physical habitat. These models compare the current conditions to two restoration scenarios that allow for fish passage given 1, 2, and 5-year flood events at two study sites. This study reveals important variations in the impact of restoration between the study sites and the reconnection methods. It also suggests that there is the potential for a large increase in the area of accessible habitat with stream restoration.
