Chau, Teresa C. "IFE, an interactive formula editor." FIU Digital Commons, 1988. http://digitalcommons.fiu.edu/etd/2117.
Full textAbstract:
IFE, the Interactive Formula Editor is an experimental system designed, developed and implemented to propose a different approach to handle mathematical formulae. Its main characteristics are: (1) Interactive creation and edition of a mathematical formula, (2) Tex-form output for a printed version of a formula, and (3) Ability to generate a new set of characters by means of a character editor.
Mathematical symbols are provided and adjusted by the system, automatically. The system also, guides the user during the formula description because it knows the syntax of the graphical representation.
The system seems to be complete and perform well. The listing of the program is included, as are suggestions for further development.

Para las sociedades que viven bajo regímenes autoritarios o totalitarios, la democracia es un proceso lento y largo, tanto más para quienes la estudian y la viven y desean verla avanzar con mayor velocidad. El comienzo del proceso democratizador en México José Woldenberg Karakowsky lo ubica en el año de 1977; no porque antes no se hubieran escenificado fuertes y hasta heroicas luchas democratizadoras o se hallan dado aflojamientos de los amarres autoritarios.
Lo ubica en ese año porque a partir de ahí: “Se configuró la estructura del cambio, es decir, un proceso que se desarrolla en una misma dirección democratizadora, fortaleciendo partidos y cuyos momentos de expansión se cristalizaron en las negociaciones y reformas electorales” (Woldenberg, 2004: 9)
En 1977, por primera vez se abrieron las compuertas para el libre desarrollo de las opciones organizadas y para su asistencia al mundo electoral. Por lo tanto:
Se declara a los partidos políticos como entidades de interés público y de paso su constitucionalización, es decir, al reconocimiento de la personalidad jurídica de los partidos en plural y a su importancia en la conformación de los órganos del Estado. Se abre la puerta de la competencia electoral, mediante el registro condicionado a las fuerzas políticas más significativas de la izquierda mexicana hasta entonces marginadas. (Woldenberg, 2004: 9)

Full textAbstract:
Parmi les causes des retards de developpement dans les pvd il peut y avoir la contradiction entre persistance des anciens systemes de production et le mode de production industrielle. En ce qui concerne l'assainissement des eaux usees, la culture yoruba, dont ile ife etait le centre spirituel, prevoyait des dispositifs specifiques au niveau de l'unite d'habitation et le dispositif institutionnel garantissait la mise en oeuvre et l'entretien des dispositifs de drainage au niveau de la ville-etat. Aujourd'hui a ile ife les pratiques traditionnelles survivent partiellement seulement dans le centre ville ou existe encore l'ancienne organisation sociale; dans les habitats neufs, l'initiative des particuliers est limitee et celle du dispositif institutionnel moderne est presque absente. L'etat federal nigerian, malgre les demarches de formulation de politique en matiere d'assainissement, n'a pas reussi a rendre operantes les indications relatives aux programmes. Les gouvernements des etats, sauf quelques exceptions, montrent un vide d'organisation encore plus grand et les gouvernements locaux, qui sont charges de la mise en oeuvre des dispositifs d'assainissement dans leurs territoires, n'ont pas les moyens ni les techniques pour accomplir ces taches. .Contradictions between traditional and modern system of production seem to be the most important cause of the delay in the implementation, of technical devices for sanitation of wastes water in ile ife, nigeria. Traditionally the yoruba culture dealed with specific devices for waste water sanitation, centered in the housing unit (compound). The public power of the city -state was charged of the implementation and maintenance of drainage devices at the town level presently in ile ife, traditional practices still exist, in the ancient core of the town, where still survives the traditional social organisation. In the new urbanized areas of the town, only the private initiative operates, beeing the role of the local gover nement quite absent. The implementation of sanitation policies by the federal governement of nigeria has been, up to now, almost a failure. The states governements, with some exceptions, failed to organize sanitation services; the local councils, charged of the implementation of sanitation devices in their area of governement have not financial and technical tools to reach their tasks. .

Sogbesan, Oluwatoyin Zainab. "The potential of digital representation : the changing meaning of the Ife 'bronzes' from pre-colonial Ife to the post-colonial digital British Museum." Thesis, City, University of London, 2015. http://openaccess.city.ac.uk/17212/.
Full textAbstract:
For many years, meanings and interpretations of artefacts that are taken to represent African culture including the Ife bronzes have been predominantly produced and fixed by a team of western curatorial experts (Ciolfi, 2012). Such museum practices have prevented visitors and the people being represented by the artefact from participating in the process of interpretation and meaning-making. In the particular case of the ‘Ife bronzes’, the previous meaning and implications of the Ife ‘bronzes’ as part of ‘the cradle of the world’, according to Yoruba oral traditions, are yet to be given the amount of attention they deserve. For a long time the interpretations and meanings produced by curators were drawn from the writings and accounts of earlier western travellers, explorers and colonial officials whose culture affected how the Ife bronzes have been perceived and interpreted (Coombes, 1997: Vogel, 1999). Today despite the impact of ‘the new museology’, strong traces of such biased interpretations and meanings are still evident in the framing of the Ife bronze head, exhibited at the British Museum Sainsbury African gallery as a ‘funerary object’ in postcolonial times. Such narratives highlight ‘relations of power and not relations of meanings’ (Foucault, 1980:114). These contemporary exhibitionary frames highlight the need for interpretations and meanings that will consider how changing roles, ownership, usage, political situations and geographical location have affected and will affect the Ife bronzes. In this thesis I carry out this work, documenting the social life of the Ife bronzes from pre-colonial Ife to postcolonial digital British Museum. I argue that there is a need for a new space that will encourage rewriting, revising and representing the Ife bronzes in a more capacious way to depict their changing meaning as they journeyed through time. This theory is in line with Hall (1997) and Foucault’s (1980) theories that meanings and interpretations are not static but are affected by time and changing context. The thesis therefore explores the multifaceted political, economical and sociocultural implications of the Ife bronzes. Despite these wider implications of Ife bronzes, they are still only too often shrouded in narratives that tend to validate the supremacy, civilisation and intellectual ‘supremacy’ of the West instead of substantiating the ingenuity, civilisation and intellectual capabilities of Africa. Digitisation is critically considered as offering a potential new space for representing Ife bronzes in a new light that might allow meanings with postcolonial ideology to emerge. Focusing on different periods involving the Ife bronzes (the pre-colonial, colonial and postcolonial) the thesis explores the potentials of digital representation. The thesis concludes that digital representation but only combined with a critical contextual approach, have the potentials of initiating a more thorough decolonisation of the Ife bronzes through an inclusive participatory culture.

Full textAbstract:
The aim: The overall aim of this licentiate thesis was to describe and analyze oral health-related quality of life measured with OHIP-14. The thesis comprises two studies, each with a specific aim.
Study I: To describe oral health-related quality of life measured with OHIP-14 in an Swedish adult population
Study II: To study the relationship between oral health-related quality of life, measured with OHIP-14, and subjective as well as objective dry mouth conditions in fragile old people. Furthermore, the aim was to study the reliability and validity of a new instrument (VAS) to measure dry mouth
Material and methods: Study I comprised a stratified random sample of 519 individuals 20-80 years of age. In Study II, 41 randomly selected fragile old people, residents at three different community care centers, participated. In both studies, the questionnaire OHIP-14 was used for measurement of oral health-related quality of life. The participants in Study II answered a questionnaire for subjectively experienced dry mouth (VAS). For objective dry mouth measurements, saliva was absorbed into a preweighted cotton roll.
Results: In Study I, 21% of the respondents stated that they had no oral problems that had a negative impact on their well-being. In Study II, the corresponding figure was 71%. In study I the mean value for OHIP-14 was 6.4 (SD=7.1) for the entire population; 5.9 (SD=7.1) for men and 6.8 (SD=7.2) for women in. Subjects, who frequently experienced problems related to oral health, with scores ranging from 16 to 41 points, accounted for 10% of the study group. In Study II, significant associations were identified between both objectively measured respective subjectively experienced dry mouth and oral health-related quality of life. The validity of the VAS instrument was good for subjective mouth dryness, but poor for objectively measured dry mouth in fragile old people.
Conclusion: From Study I it can be concluded that, in this Swedish population, a number of individuals, both young and old, experience oral problems that have a negative impact on their well-being. From Study II, the conclusion is that dry mouth (both objective and subjective) is significantly associated with poorer oral health-related quality of life, underlining the value of monitoring dry mouth conditions in the care of fraigile old people.

Full textAbstract:
Comment les ife se percoivent-ils et comment expriment-ils le monde qui les entoure et celui dont ils imaginent l'existence? tel est le sujet de cette these. Pour la rediger, nous avons reuni et examine plus de cinq cents textes appartenant a tous les genres oraux attestes parmi les ife, tant du registre profane que du registre sacre. Il apparait d'apres ces textes que les ife croient en plusieurs divinites reunies dans un pantheon suffisamment hierarchise pour qu'on y distingue des dieux cosmiques et des dieux locaux. Si l'individu sacrifie a plusieurs divinites, le groupe clanique auquel il appartient ne reconnait en general qu'un seul dieu. Alors faut-il parler a propos de ce groupe de monotheisme ou de polytheisme? la question se pose d'autant plus que si les ife croient en un etre superieur aux divinites, ils ne lui adressent aucun culte. Les ife portent un regard attentif au monde qui les entoure et il est interessant de noter que les traits qu'ils reconnaissent aux etres et aux choses nourrissent leurs creations litteraires. Ainsi les contes, les chansons, les devises, etc. Revelent un monde anthropomorphique. On ne parle pas dans ces textes que des dieux et du monde, mais aussi de l'homme qui est peint avec une tres grande precision de traits tant physiques que moraux. La litterature orale des ife n'est pas qu'une vision du monde. Elle est aussi un art dont nous avons analyse les caracteristiques dans le septieme et dernier chapitre de notre theseWhich perception do the ife people have of themselves and how do they express the world around them and the world they imagine? that is the subject for this thesis. In order to write it, we collected and examined more than five hundred texts belonging to all oral types known among the ife, of profane and sacred register. According to these texts, it occurs that the ife believe in many gods gathered into a sufficient hierarchy to distinguish cosmic gods and local ones. If the individual sacrifices to many gods, the clanic group to which he belongs generally does not recognize but one god. So can we speak of monotheism or polytheism about this group? that is an ever more important question that if the ife believe in a being which is above divinities, they don't worship it. The ife people look attentively at the world around them and it is interesting to notice that the features they recognize to beings and things are used for their literary creations. So tales, songs, mottos, etc. . . Reveal an anthropomorphic world. We don't speak in those texts only of gods and the world, but also of man who is painted with a great precision in his physical and moral features. Oral litterature among the ife people is not only a vision on the world. It is also an art and we have analyzed the typical features of this art in the seventh and last chapter of our thesis

En el siguiente trabajo para entender lo descrito, se utilizan tres métodos que facilitaran la recolección, el análisis y la comparación de resultados de la investigación. El Primer método es el analítico porque este permite desmenuzar las reformas políticas más transcendentales en nuestro sistema electoral. El segundo es el método descriptivo, este permite entender como ha sido el proceso evolutivo de las mismas, dando una interpretación para su explicación. Por último el tercer método utilizado es el comparativo ya que nos permite observar que información manejan los distintos medios electrónicos en relación con la reforma político electoral 2014, esto a través de un cuadro comparativo, dividendo el proceso en dos: lo más relevante antes de las elecciones del 2015 y un después del proceso electoral, para que de esta manera se logre entender cuál era la información que se manejaba y las consecuencias que pudieron observarse.

Full textAbstract:
In-flight entertainment (IFE) is facing exciting times ahead as more and more technological advancements find its way into the IFE-systems. With the increasing hardware capabilities of IFE-systems, one exciting technology which could be seen infuture IFE-systems is augmented reality (AR). AR could allow for virtual try-on (VTO) in a webshop, where passengers can view virtual representations of for instance, glasses or headpieces, augmented onto themselves through a camera on the IFE-screen. However, integrating VTO in a webshop comes with new challenges, both for the designer and the developer. This thesis has examined design guidelines for AR in a literature study, along with general principles for user experience (UX). Based on the findings from the literature study, a prototype for a webshop with integrated VTO, targeting IFE, has been build in an iterative design process. Furthermore, a small application has been built using Google’s AR-framework ARCore for Android, where users can try different virtual glasses. The literature study, along with usability testing in each design iteration, showed that there are no guidelines which can cover everything when designing for AR; however, the design guidelines presented by Google and Apple are a great place to start. Furthermore, the usability testing showed that people have certain expectations of a webshop, which indicates that VTO should be integrated seamlessly into the application without interfering with the layout. The application development showed that ARCore certainly is a potent tool when it comes to AR-development. However, ARCore is not open source,which could make it less appealing for companies in need of highly flexible solutions.

Full textAbstract:
The thesis explores how three prominent themes in social relationships - namely, status, solidarity and social mobility - are manifested in different lifestyle settings, by analysing the dynamics of culinary practice within the domestic space, based on an ethnographic study of seventy five households from the mid 1990s in Ile-Ife, Nigeria. Many ethnographic studies identify the kitchen as a gendered space, and argue that because gender defines status and power relations in society, such distinctions will be manifested in the way space was designed and used. A gendered space is therefore a status space. The purpose of this study is show how status is manifested in space, and to measure this manifestation by analysing the distribution of culinary practices in space. The sample cuts across the socio-economic strata of Ile-Ife, and within these neighbourhoods, people live in two distinct spatial patterns, whereby one shares their domestic space with other households, while the other lives separately from other households. By using a combination of architectural morphology tools based on the space syntax theory and descriptive statistics, the study analyses the shared presence of persons, objects, activities, and food in space in order to measure the interrelationship between space and social status. The study found that there was a tendency for the status of variables to be influenced by other variables that shared the same spatial environment. The study found that higher status culinary activities and objects were associated with segregated spaces in shared accommodation, which suggests that segregation correlates with exclusivity. However, in the modern self-contained households, higher status activities took place in integrated spaces and in this sense fostered inclusion with the family. Socially, the findings suggests that there is a convergence of social positions and blurring of age and gender role boundaries in relation to culinary activity, with increased socioeconomic status and social mobility of women.

This research has had as a general goal to analyze the esp-t course from the online Erasmus platform which is addressed to health professionals. The technological and methodological aspects have been investigated through a comparative analysis of the ICT resources and methodology used in this course along with the criteria listed in the reference frameworks of Doughty and Long (2003) and Basturkmen (2006, 2010). This is a qualitative research, evaluative in type, with descriptive exploratory objective. Our research was based on a literature review on teaching ESP for health professionals in the digital context. The esp-t course was selected because it is a free ESP course, available online with open access to therapists and to health professionals aiming at language improvement for certification purposes. The researcher has enrolled herself in this course so she could live the experience of studying IFE in an open virtual platform and could develop a reflective diary, composed of personal notes and screenshots of the course attended. The data were analyzed based on reference frameworks and the results have shown that although the platform has the potential for the use of interactive activities, there is a predominance of exercises aiming at the development of reading and listening comprehension language skills.
Esta pesquisa teve como objetivo geral analisar o curso esp-t da plataforma online Erasmus destinado a profissionais da saúde. Foram investigados os aspectos tecnológicos e metodológicos, através de uma análise comparativa dos recursos de TDICs e metodológicos empregados nesse curso com os critérios elencados nos quadros referenciais de Doughty e Long (2003) e Basturkmen (2006, 2010). Este estudo configura-se como uma pesquisa qualitativa, do tipo avaliativa, com objetivo descritivo exploratório. Nossa pesquisa foi fundamentada em uma revisão de literatura sobre ensino de Inglês para Fins Específicos para profissionais da saúde em contexto digital. O curso esp-t foi selecionado por se tratar de curso de IFE, disponibilizado gratuitamente online e de acesso aberto para profissionais terapeutas da saúde que visam aprimoramento linguístico para fins de obtenção de certificação. A pesquisadora matriculou-se nesse curso para que pudesse vivenciar a experiência de estudar IFE em uma plataforma virtual aberta e pudesse desenvolver um diário reflexivo, composto por anotações pessoais e capturas de tela do curso frequentado. Os dados obtidos foram analisados com base nos quadros referenciais e os resultados mostraram que apesar de a plataforma ter o potencial para a utilização de atividades interativas, há um predomínio de atividades que visem ao aprimoramento de habilidades linguísticas de leitura e de compreensão oral.

Previous issue date: 2012-03-06This study presents the results of a survey conducted in the area of English for Specific Purposes (ESP) in order to identify (1) the learning needs of students in a course in Tourism, their desires and lacks, at a federal university, with respect to use of English; (2) the needs of the present situation of teachers and the coordinator of that course as to the language; (3) the needs of the target situation of professionals (graduates) and companies with respect to this language. This research is a case study (STAKE, 1998; YIN, 2009) and was used for data collection, instruments such as questionnaires, semi-structured interviews, and document on the Tourism Course. To this end, it was adopted the theoretical basis for the constructs of English for Specific Purposes (ESP) Ingl?s para Fins Espec?ficos (IFE) in Brazil, also known as Ingl?s Instrumental, whose foundation is based on the work by Hutchinson and Waters (1987), Robinson (1991), Dudley-Evans and St. John (1998), Celani, Deyes, Holmes, Scott (2006), among others, since this work is devoted to a specific area, Tourism. Results show that students opined the ability to prioritize reading and speaking into the classroom. Professionals reported that the latter is an indispensable tool for entering the labor market, yet they feel unprepared and need to attend English language courses in private language schools. The testimony of company executives also point to this deficiency. Finally, the present situation of teachers reveals that, while advocating the use of English in the classroom, this is not because students prefer their mother tongue. There is also an evident lack of needs analysis. Eventually, the coordinator said that there is some uncertainty as to the methodology, content and language skills worked, and the lack of interaction among teachers of English. It was concluded, therefore, it is important to conduct a needs analysis so that one can redesign a course that meets the different contextual needs: students, teachers, coordination, represented by the institutional needs, and the labor market
Este estudo apresenta os resultados de uma pesquisa desenvolvida na ?rea de Ingl?s para Fins Espec?ficos (IFE) com o objetivo de identificar (1) as necessidades de aprendizagem dos alunos de um curso de Turismo, seus desejos e car?ncias, numa universidade federal, quanto ao uso do ingl?s; (2) as necessidades da situa??o atual dos professores e do coordenador do referido curso quanto ao idioma; (3) as necessidades da situa??o-alvo dos profissionais (egressos) e empresas com rela??o a essa l?ngua. Esta pesquisa ? um estudo de caso (STAKE, 1998; YIN, 2009) e foram utilizados, para levantamento dos dados, como instrumentos de coleta: question?rios, entrevistas semiestruturadas, al?m de documento sobre o curso de Turismo. Para tanto, foram adotados como aporte te?rico os construtos do English for Specific Purposes (ESP) Ingl?s para Fins Espec?ficos (IFE) tamb?m conhecido no Brasil como Ingl?s Instrumental, cuja fundamenta??o baseia-se nos trabalhos de Hutchinson e Waters (1987), Robinson (1991), Dudley-Evans e St. John (1998), Celani, Deyes, Holmes, Scott (2006), dentre outros, visto que este trabalho ? voltado para uma ?rea espec?fica, o turismo. Os resultados demonstram que os alunos opinaram pela habilidade em leitura e priorizaram a oralidade em sala de aula. Os egressos relataram que esta ?ltima ? uma ferramenta indispens?vel para sua entrada no mercado de trabalho; mesmo assim, sentem-se despreparados, necessitando frequentar escolas de l?ngua. O depoimento dos dirigentes de empresas tamb?m aponta para essa defici?ncia. Por ?ltimo, a situa??o atual dos professores denota que, embora defendam o uso da l?ngua inglesa em sala de aula, isso n?o acontece, porque os alunos preferem a l?ngua materna. Tamb?m ficou evidenciada a inexist?ncia de an?lise de necessidades. Por fim, a coordenadora informou que h? certa indefini??o quanto ? metodologia, aos conte?dos e ?s habilidades lingu?sticas trabalhadas, al?m da falta de intera??o entre os professores de ingl?s. Conclui-se, portanto, que ? relevante realizar uma an?lise de necessidades para que se possa redesenhar um curso que atenda ?s diferentes necessidades contextuais: de alunos, professores, coordena??o, representada pelas necessidades institucionais, profissionais e o mercado de trabalho

Full textAbstract:
International Fisher Effect (IFE) is a theory in international finance which asserts that the spot exchange rate between countries should move in opposite direction with the interest rate differential between these countries. The aim of this thesis is to analyze whether differences in nominal interest rates between countries and the movement of spot exchange rates between their currencies tend to move together over the long run. The presence of IFE is tested among the G-5 countries and Turkey for the period from 1985:1 to 2007:12. The long run relationship is estimated with the Johansen co-integration method and supportive evidence is found for all country pairs. Individually modeled equations are further tested with the Dynamic SUR method. Those DSUR equations that include the Turkish currency provide supportive evidence for IFE that higher interest rates in favor of Turkey would cause depreciation of the Turkish Lira. The magnitude of the effect is found to be lower than expected which indicates that there might be other factors in economy, such as inflation rates, that affect the exchange rate movements.

Full textAbstract:
In this thesis an implementation of an Android application is made. The application is able to run on both an Android based In Flight Entertainment system screen, as well as on an Android smartphone. When two instances of the application is run on different systems, the two application instances are able to communicate with each other via UDP or Bluetooth. The implementation of the communication is evaluated. For implementations demanding high goodput, UDP is better suited than Bluetooth which is consistent with results of previous studies. For implementations where response times are more important than goodput, Bluetooth is considered to still be a viable option. The results shows that the hardware performance of the system running the application greatly impacts the resulting goodput and response times of the communication. Hardware performance is therefore concluded to be the biggest hurdle to overcome when implementing demanding application communication between smarthphones and the In Flight Entertainment systems targeted in this study.I detta examensarbete så skapas en Android applikation. Applikationen kan köras på både en Androidbaserad In Flight Entertainment skärm, samt en Android smartphone. När två instanser av applikationen körs på olika enheter så kan applikationerna kommunicera med varandra via UDP eller Bluetooth. Implementationen av kommunikationen utvärderas. För implementationer som kräver högre goodput så är UDP bättre lämpat att använda än Bluetooth, vilket är konsekvent med resultat från tidigare utförda studier. För implementationer där låg responstid är viktigare än hög goodput, så är Bluetooth dock inte ett uteslutet alternativ. Resultatet visar att hårdvaruprestandan hos den enhet som applikationen körs på har en stor påverkan på kommunikationens goodput och responstid. Utifrån detta så dras slutsatsen att påverkan från hårdvaruprestandan är den största begränsningen som behöver adresseras vid implementation av krävande applikationskommunikation mellan smarttelefoner och de In Flight Entertainemet system som använts i denna studie.

Full textAbstract:
Composites have been increasingly used in different applications in the last decade, especially in aerospace due to their high strength and lightweight characteristics. Indeed, the latest models of Airbus (A350) and Boeing (B787) have employed more than 50 wt% of composites, mainly Carbon Fibre Reinforced Polymers (CFRP). Yet, the increased use of CFRP has raised the environmental concerns about their end-of-life related to waste disposal, consumption of non-renewable resources for manufacturing and the need to recycle CFRP wastes. In this study, a generic model is developed in order to propose an optimal management of aerospace CFRP wastes taking into account economic and environmental objectives. Firstly, a life-cycle systemic approach is used to model the environmental impacts of CFRP recycling processes focusing on Global Warming Potential (GWP) following the guidelines of Life Cycle Assessment (LCA). The whole supply chain for recycling CFRP pathways is then modelled from aircraft dismantling sites to the reuse of recycled fibres in various applications. A multi-objective optimisation strategy based on mathematical programming, -constraint and lexicographic methods with appropriate decisionmaking techniques (M-TOPSIS, PROMETHEE-GAIA) has been developed to determine CFRP waste supply chain configurations. Various scenarios have been studied in order to take account the potential of existing recycling sites in a mono-period visions as well as the deployment of new sites in a multi-period approach considering the case study of France for illustration purpose. The solutions obtained from optimisation process allow developing optimal strategies for the implementation of CFRP recovery with recycled fibres (of acceptable quality) for the targeted substitution use while minimising cost /maximising profit for an economic criterion and minimising an environmental impact based on GWP.

Full textAbstract:
Att kunna exportera färdiga modeller direkt från Revit till IDA är av stor betydelse för att kunna jobba effektivt med energisimuleringar. Denna rapport ger en bakgrundsbeskrivning till hur IFC har uppkommit och är uppbyggt. Dock ligger huvudfokus på hur Revit kan implementeras i arbetsflödet, där både hur IFC-filer överförs mellan programmen och felsökning av problem med befintliga Revitmodeller beskrivs. IFC-filer är dagens standard för att överföra data mellan olika instanser under byggprocessen, det är ett programoberoende format som möjliggör samarbete mellan olika programvaror. Dagens standard är IFC4, men det vanligaste formatet idag är IFC2x3 då det nya formatet ännu inte har implementerats i alla programvaror. Vilken geometri och information som ska exporteras från Revit till IDA är ett omfattande arbete att ta reda på och ställa in. Därför innehåller denna rapport både en lathund för exportering, men även flera filer för automatisk inladdning av korrekta exporteringsinställningar i Revit. För att kunna genomföra en energisimulering krävs det att rummen är förslutna för att undvika extrema köldbryggor som kan uppstå om väggarna inte är ordentligt anslutna med taket och golvet. Därför finns flera åtgärder beskrivna för att undvika fel i simuleringen, bland annat kring problem med fönster, dörrar och problem med lagerhantering. Beskrivningen utgår ifrån att användaren inte har tidigare erfarenhet av Revit. Guiderna har testats på en gymnasieklass i ämnet CAD där resultatet visade att en stor del av lathunden kan användas av en nybörjare. Dessutom studeras skillnader i Revits verktyg för simulering mot IDA. Där samma modell simulerades på åtta olika platser och standardavvikelsen mellan resultatet beräknades, detta gav ett koefficientintervall på ± 4 %, dvs. att en simulering i IDA inte bör avvika med mer än ± 4 % i jämförelse med den som gjordes i Revit. Liknande resultat uppmättes när simuleringsskillnader i dörrar och fönster simulerades. Där en stor glasyta på en vägg kommer generera ett koefficientintervall på 3 %. Om fönstren ersätts av dörrar kommer avvikelsen att minska något till strax under 2 % sett till alla väderstreck.It is extremely important to be able to export models directly from Revit to IDA for the energy simulations to be efficient. This report has a background description about how the IFC-format has been developed and how it is structured. However, the focus in the report is on how Revit can be implanted in the workflow, where both export and troubleshooting from Revit are described. IFC is the standard today to export data between various parts during the construction process and it is a format that is program independent, which means that it works across different applications. The current version of IFC is IFC4, but IFC2x3 is still the most used version since not every program has support for the new IFC4 format. It is extensive to figure out which data IDA requires for energy simulations, therefore this report contains both a tutorial for export settings and a file for automatic set correct export settings in Revit. To succeed with the energy simulations a requirement is that the space in the building is enclosed with walls, floor and roof, otherwise extreme thermal bridges will cause incorrect simulations. Therefore, there are several workarounds described in this report to correct these problems, including problems with windows, doors and problems with storage facilities . The description in this report is written with the assumption that the user do not have any experience with Revit. The guides were tested on a class of high school students that are studying the course CADCAD02. The result showed that when a problem occurs with a model it can easily be solved with the support from this report. Further differences between simulations in Revit and IDA were tested. The same model was simulated in eight different places and the standard deviation was calculated, this gave the coefficient range ±4 %, i.e. a simulation in IDA should not differ more than 4 % from the simulation in Revit. Similar results were found with the simulations of windows and doors, even though the difference was slightly lower.

In this paper we sought to understand how the Degree in Physics in IFG Goiânia campus is structured and what the perspective of teachers in the area, specifically in the implementation of degree in Physics, and forward the changes in the institution. The choice of this theme is due to the requirement stipulated by law 11.892 of December 29, 2008, the Federal Institutes of Education, Science and Technology, in offering undergraduate courses, especially in the areas of Science and Mathematics, despite its recognized expertise in professional education. Some research has dealt with the theme of the presence of the degrees in FIs, discussing the profile, the deployment and the challenges that they are consoli dated. However, here we seek teachers' perception of the process. Characterized as a qualitative study we used bibliographical research to survey the changes via legal documents in the institution, as well as research on the site e -MEC for recognizing the quantity of courses offered in this mode before and after the creation of the IFs. For analysis of the survey responses a nd interviews with teachers of Physical area of Goiânia the IFG campus, we used content analysis, according to Bardin (2002). It was identified as perceived by teachers who: (i) changes in the institution provided an expansion and internalization, even disorderly; (Ii) the change in the teaching profession and school mischaracterization with devaluation of technical education; (Iii) the course designed to meet the law, structure and operation in construction, has a focus on specific knowledge at the expense of teaching; (Iv) teachers work almost exclusively in the classroom, with little or no research and extension activities. These aspects lead to understand that there is still a lack of identity in I Fs after implantation of degrees and forward the changes in this institutions.
Neste trabalho buscou-se compreender de que forma a Licenciatur a em Física no campus Goiânia do IFG se estrutura e qual a perspectiva dos professores da área , especificamente, na implantação da licenciatura em Física , e frente as mudanças ocorridas na instituição. A escolha deste tema se deve pela obrigatoriedade, estipulada pela lei 11.892 de 29 de dezembro de 2008, dos Institutos Federais de Educação, Ciência e Tecnologia, em ofertar cursos de licenciaturas, principalmente nas áreas de Ciências e Matemática, apesar de sua reconhecida competência na área de educação p rofissional. Algumas pesquisas têm tratado da temática sobre a presença das licenciaturas nos IFs, discutindo o perfil, a implantação e os desafios para que os mesmos sejam consolidados. No entanto, aqui buscamos a percepção dos professores sobre todo o pr ocesso. Caracterizado como um trabalho de abordagem qualitativa utilizou-se inicialmente de pesquisa bibliográfica para levantamento das alterações ocorridas via documentos legais na instituição, assim como pesquisa no site e -MEC para o reconhecimento do quantitativo de cursos ofertados nesta modalidade antes e depois da cria ção dos IFs. Para análise das respostas do questionário e das entrevistas realizadas com os professores da área de Física, do campus Goiânia do IFG, utilizou-se a Análise de Conteúdo, segundo Bardin (2002). Identificou-se, segundo a percepção dos professores que: (i) as mudanças na instituição proporciona ram uma expansão e interiorização, mesmo que desordenada ; (ii) a alteração na carreira do professor e a descaracterização da escola com desvalorização do ensino técnico; (iii) o curso criado para atender a lei, com estrutura e funcionamento em construção, possui um enfoque no conhecimento específico em detrimento do pedagógico; (iv) os professores atuam quase que exclusivamente em sala de aula, com poucas ou nenhuma atividade de pesquisa e de extensão. Estes aspectos levam a entender que há ainda uma falta de identidade nos IFs após a implantação das licenciaturas e frente as mudanças ocorridas nesta s instituições.

Full textAbstract:
2011 - 2012Today public-key cryptographic is widely deployed and successfully used but still a major drawback exists. In fact, from encrypted data a party can either decrypt or cannot learn anything at all about the message other than intentionally leaked information such as its length. In the recent years, the cloud computing paradigm has emerged as the new standard to use computing resources, such as storage devices, that are delivered as a service over a network. In such a scenario, the notion of public key cryptography is not enough. It would be desirable to specify a decryption policy in the encrypted data in such a way that only the parties who satisfy the policy can decrypt. In a more general form, we may want to only give access to a function of the message, depending on the decryptor’s authorization. Thus, in the last decade researchers have started looking at a more sophisticated type of encryption called functional encryption. A functionality F is a function F : K × M ! where K is the key space and M is the message space. In the public-key setting, a functional encryption scheme for F is a special encryption scheme in which, for every key k 2 K, the owner of the master secret key msk associated with the master public key mpk can generate a special secret-key skk that allows the computation of F(k,m) from a ciphertext of m 2 M computed under public key mpk . In other words, whereas in traditional encryption schemes decryption is an all-or-nothing affair, in functional encryption it is possible to finely control the amount of information that is revealed by a ciphertext. One of the most notable example of functional encryption is identity-based encryption first introduced by Shamir as an alternative to the standard notion of public-key encryption. In this thesis, we discuss several instantiations of function encryption that can all be seen as generalisations of identity-based encryption. We improve on previous constructions in terms of performance and security guarantees. [edited by author]

Full textAbstract:
Dans le cadre de cette thèse, une approche de calcul de couplage multi-échelle et multi-physique en 2D et en 3D est présentée. La modélisation multi-échelle d’une structure consiste de l’échelle macro qui représente la réponse homogénéisée de la structure entière, tandis que l’échelle micro peut capturer les détails du comportement à la petite échelle du matériau, où des mécanismes inélastiques, tels que la plasticité ou l’endommagement, peuvent être pris en compte. L’intérieur de chaque macro-élément est rempli par le maillage à l’échelle micro qui s’y adapte entièrement. Les deux échelles sont couplées à travers le champ de déplacements imposé à l’interface. Le calcul par éléments finis est effectué, en utilisant une procédure de solution operator-split sur les deux échelles. En 2D, une discontinuité dans le champ de déplacements est introduite à l’échelle macro dans un élément fini Q4, pour pouvoir capturer l’adoucissement comportement d’un matériau piézoélectrique. Un degré de liberté supplémentaire qui représente le voltage est ajouté aux noeuds des macro-éléments de tétraèdre et d’hexaèdre en 3D. La poutre de Timoshenko comportant un modèle de commutation de polarisation est utilisée à l’échelle micro. Également, une formulation multi-échelle de Hellinger-Reissner a été développée et implémentée pour un simple patch test en électrostatique. La procédure proposée est mise en œuvre dans le logiciel de calcul par éléments finis FEAP - Finite Element Analysis Program. Pour simuler le comportement aux deux échelles, FEAP est modifié, et deux versions différentes du code sont obtenues - macroFEAP et microFEAP. Le couplage de ces codes est réalisé avec Component Template Library - CTL qui rend possible l’échange d’informations entre les deux échelles. Les capacités de cette approche multi-échelle en 2D et en 3D sont démontrées dans un environnement purement mécanique, mais aussi multi-physique. La formulation théorique et l’application algorithmique sont présentées, et les avantages de la méthode multi-échelle pour la modélisation des matériaux hétérogènes sont illustrés avec plusieurs exemples numériquesIn this thesis, a multi-scale and multi-physics coupling computation procedure for a 2D and 3D setting is presented. When modeling the behavior of a structure by a multi-scale method, the macro-scale is used to describe the homogenized response of the structure, and the micro-scale to describe the details of the behavior on the smaller scale of the material where some inelastic mechanisms, like damage or plasticity, can be taken into account. The micro-scale mesh is defined for each macro-scale element in a way to fit entirely inside it. The two scales are coupled by imposing a constraint on the displacement field over their interface. The computation is performed using the operator split solution procedure on both scales, using the standard finite element method. In a 2D setting, an embedded discontinuity is implemented in the Q4 macroscale element to capture the softening behavior happening on the micro-scale. For the micro-scale element, a constant strain triangle (CST) is used. In a 3D setting, a macro-scale tetrahedral and hexahedral elements are developed, while on the micro-scale Timoshenko beam finite elements are used. This multi-scale methodology is extended with a multi-physics functionality, to simulate the behavior of a piezoelectric material. An additional degree of freedom (voltage) is added on the nodes of the 3D macro-scale tetrahedral and hexahedral elements. For the micro-scale element, a Timoshenko beam element with added polarization switching model is used. Also, a multi-scale Hellinger- Reissner formulation for electrostatics has been developed and implemented for a simple electrostatic patch test. For implementing the proposed procedure, Finite Element Analysis Program (FEAP) is used. To simulate the behavior on both macro and micro-scale, FEAP is modified and two different version of FEAP code are implemented – macroFEAP and microFEAP. For coupling, the two codes are exchanging information between them, and Component Template Library (CTL) is used. The capabilities of the proposed multi-scale approach in a 2D and 3D pure mechanics settings, but also multi-physics environment have been shown. The theoretical formulation and algorithmic implementation are described, and the advantages of the multi-scale approach for modeling heterogeneous materials are shown on several numerical examples

Full textAbstract:
Dans le contexte de la micro-robotique, cette thèse vise à développer une méthode de localisation et de suivi optique de micro-convoyeurs se déplaçant sur une surface. Le principe de la méthode de localisation proposée consiste à détecter un faisceau réfléchi sur le micro-convoyeur et à analyser ce signal optique pour obtenir les positions correspondantes. Les principaux éléments du système sont un rétroréflecteur à coin cube placé sur un micro-convoyeur et qui permet de réfléchir le signal optique dans sa direction incidente, un miroir MEMS qui permet de balayer la surface avec un éclairement laser, un séparateur de faisceau qui est un composant optique utilisé pour guider la lumière réfléchie vers un photodétecteur utilisé pour assurer la localisation et le suivi à travers l’exploitation du signal détecté par ce dernier. L’importance de la localisation est d’optimiser la trajectoire suivie par les micro-convoyeurs en contrôlant leur position et leur vitesse pour finalement pouvoir localiser les micro-convoyeurs avec une grande précision et éviter d’éventuelles collisions entre eux. Pour faire des tests expérimentaux et évaluer le capteur développé, la surface utilisée est une surface de micro-convoyage basée sur un principe électromagnétique, développée au laboratoire Roberval. Une calibration du système, en utilisant l’homographie, a été effectuée afin d’assurer la localisation et le suivi du micro-convoyeur pour après contrôler sa trajectoire et sa vitesse. Une localisation et un suivi simultané de deux micro-convoyeurs en utilisant un multiplexage temporel a été également développé et validé dans ce travailThis thesis aims to develop a method for optical localization and tracking of microconveyors moving over a surface in the context of micro-robotics. The principle of the proposed localization method consists of detecting a beam that is reflected on the micro-conveyor and analyzing this optical received signal to obtain the corresponding positions. The main elements of the system are a corner cube reflector, a MEMS mirror and a beam splitter. The corner cube is placed on the micro-conveyor in order to allow the optical signal to be reflected in its incident direction. The MEMS mirror allows the surface to be scanned with the laser. As for the beam splitter, it is an optical component used to guide the reflected light to a photodetector which is in turn used for localization and tracking through the exploitation of the signal that it detects. The important role of localization is to optimize the trajectory followed by the micro-conveyors. This could be achieved by controlling the respective position and speed of each of them in order to be finally able to localize the micro-conveyor with high precision and to avoid possible collisions between them. The surface used is a micro-conveying surface based on an electromagnetic principle, developed at the Roberval laboratory. The surface is used to perform experimental tests and to evaluate the developed sensor. A system calibration, using homography, was carried out in order to ensure the localization and tracking of the micro-conveyor, and then to control its trajectory and speed. Simultaneous localization and tracking of two micro-conveyors using time division multiplexing was also developed and validated in this work. An application of the thesis at the macroscopic scale is presented as well through applying free space optical communication between two mobile systems controlled by closed-loop optical tracking. Each system includes an active transmitter and a receiver (instead of a passive corner cube reflector in the case of the micro-conveyor). The system is driven by two servomotors which permit it to have free movement in three-dimensional space. The two modules must be aligned in order to be able to send and receive information by laser and thus communicate. In this case, a high-precision tracking system which is capable of aligning the two moving modules is required

Full textAbstract:
La modélisation des matériaux nano-renforcés nécessite de prendre en compte l’effet de taille induit par les phénomènes locaux à l’interface entre la nanoinclusion et la matrice. Cet effet de taille est interprété par une augmentation du rapport interface/volume et peut être pris en compte en introduisant une élasticité surfacique à l’interface. Alors que de nombreux travaux ont été développés du point de vue analytique, peu de contributions ont trait à la description numérique et à la mise en œuvre de cette élasticité surfacique dans la méthode des éléments finis (FEM). Nos études visent à développer des outils numériques efficaces basés sur la FEM pour la modélisation de nanocomposites. Dans un premier temps, nous évaluons les deux stratégies numériques existantes, à savoir l’approche XFEM et l’approche des éléments d’interface, dans la reproduction de l’effet de taille dans le processus d’homogénéisation. Deuxièmement, sur la base d’un test de performance des trois types de formulations d’E-FEM dans le cas de discontinuités faibles, nous proposons une formulation améliorée de SKON permettant d’intégrer l’effet d’une interface cohérente. Enfin, la modélisation numérique du comportement non linéaire des nanocomposites est étudiée. Lors de la première étape, une loi élastoplastique de type von Mises avec durcissement linéaire isotrope est considérée pour le volume, tandis que l’interface est considérée comme élastique linéaireThe modelization of nano-reinforced material requires to take into account the size effect caused by the local phenomena at the interface between the nano-inclusion and the matrix. This size effect is interpreted through an increase in the ratio interface/volume and can be taken into account by introducing a surface elasticity at the interface. Whereas a lot of works have been developed from the analytical point of view, few contributions are related to numerical description and implementation of such surface elasticity in Finite Element Method (FEM). Our studies aim to develop efficient numerical tools based on FEM for the modeling of nanocomposites. Firstly, we evaluate the two existent numerical strategies namely the XFEM approach and the Interface element approach in reproducing the size effect in the homogenization process. Secondly, based on a performance test on the three types of formulations of E-FEM for the case of weak discontinuity, we propose an enhanced SKON formulation allowing to incorporate the effect of a coherent interface. Finally, the numerical modeling on the nonlinear behavior of nanocomposites is investigated. In the first step, a von Mises type elastoplastic law with linear isotropic hardening is considered for the bulk while the interface is considered as linear elastic

Les acides linoléique (LA) et α-linolénique (ALA) sont deux acides gras polyinsaturés. Ils sont indispensables à l’Homme car nous sommes incapables de les synthétiser in situ. Ces deux acides gras sont les représentants des oméga-6 (LA) et oméga-3 (ALA). Bien qu’ils soient indispensables et donc nécessaires, l’enjeu du ratio oméga-6/oméga-3 entre ces deux familles est également important à prendre en compte dans l’alimentation. Les habitudes de consommation des Français, ces trente dernières années, ont fait évoluer la balance en défaveur des oméga-3 par rapport aux oméga-6. Or un rééquilibre de la balance oméga-6/oméga-3 tend à diminuer les risques cardiovasculaires. Les huiles de lin et de cameline sont des cultures endémiques en France extrêmement riches en ALA. Elles sont les plus adaptées à une complémentation en oméga-3 d’origine végétale. Cependant, les hautes teneurs en acides gras polyinsaturés de ces huiles sont responsables de leurs faibles stabilités oxydatives. La consommation d’huiles ou de graisses oxydées n’est pas recommandée car elle peut apporter des molécules toxiques. Ainsi l’enjeu de ce projet était d’améliorer la durée de conservation d’huiles riches en acides gras polyinsaturés en valorisant les antioxydants extraits des tourteaux obtenus après trituration des graines. Parmi les molécules étudiées, l’acide gallique, l’acide caféique, le gallate de propyle ainsi que les pinorésinol et laricirésinol purifiées du lin ont montré un réel intérêt pour ralentir l’oxydation, tandis que le sécoisolaricirésinol s’est montré inefficaceLinoleic (LA) and α-linolenic (ALA) acids are two polyunsaturated fatty acids. They are essential for humans because we are unable to synthesize them in situ. These two fatty acids are the representatives of omega-6 (LA) and omega-3 (ALA). Although they are essential and therefore necessary, the issue of the omega-6 / omega-3 ratio between these two families is also important to take into account in the diet. The consumption habits of the French over the past thirty years have shifted the balance against omega-3s compared to omega-6s. Or a rebalancing of the omega-6 / omega-3 balance tends to reduce cardiovascular risks. Linseed and camelina oils are endemic crops in France extremely rich in ALA. They are the most suitable for supplementation with omega-3 of plant origin. However, the high contents of polyunsaturated fatty acids in these oils are responsible for their low oxidative stabilities. The consumption of oxidized oils or fats is not recommended because they can contribute toxic molecules. The aim of this project was to improve the shelf life of oils rich in polyunsaturated fatty acids by enhancing the antioxidant extracts of the cakes obtained after crushing the seeds. Among the molecules studied, gallic acid, caffeic acid, propyl gallate as well as pinoresinol and lariciresinol purified from flax showed a real interest in slowing down oxidation, while secoisolariciresinol was ineffective

La localisation précise constitue une brique essentielle permettant aux véhicules de naviguer de manière autonome sur la route. Cela peut être atteint à travers les capteurs déjà existants, de nouvelles technologies (Iidars, caméras intelligentes) et des cartes haute définition. Dans ce travail, l'intérêt d'enregistrer et réutiliser des informations sauvegardées en mémoire est exploré. Les systèmes de localisation doivent permettre une estimation à haute fréquence, des associations de données, de la calibration et de la détection d'erreurs. Une architecture composée de plusieurs couches de traitement est proposée et étudiée. Une couche principale de filtrage estime la pose tandis que les autres couches abordent les problèmes plus complexes. L'estimation d'état haute fréquence repose sur des mesures proprioceptives. La calibration du système est essentielle afin d'obtenir une pose précise. En gardant les états estimés et les observations en mémoire, les modèles d'observation des capteurs peuvent être calibrés à partir des estimations lissées. Les Iidars et les caméras intelligentes fournissent des mesures qui peuvent être utilisées pour la localisation mais soulèvent des problèmes d'association de données. Dans cette thèse, le problème est abordé à travers une fenêtre spatio-temporelle, amenant une image plus détaillée de l'environnement. Le buffer d'états est ajusté avec les observations et toutes les associations possibles. Bien que l'utilisation d'amers cartographiés permette d'améliorer la localisation, cela n'est possible que si la carte est fiable. Une approche utilisant les résidus lissés a posteriori a été développée pour détecter ces changements de carteLocalization is an essential basic capability for vehicles to be able to navigate autonomously on the road. This can be achieved through already available sensors and new technologies (Iidars, smart cameras). These sensors combined with highly accurate maps result in greater accuracy. In this work, the benefits of storing and reusing information in memory (in data buffers) are explored. Localization systems need to perform a high-frequency estimation, map matching, calibration and error detection. A framework composed of several processing layers is proposed and studied. A main filtering layer estimates the vehicle pose while other layers address the more complex problems. High-frequency state estimation relies on proprioceptive measurements combined with GNSS observations. Calibration is essential to obtain an accurate pose. By keeping state estimates and observations in a buffer, the observation models of these sensors can be calibrated. This is achieved using smoothed estimates in place of a ground truth. Lidars and smart cameras provide measurements that can be used for localization but raise matching issues with map features. In this work, the matching problem is addressed on a spatio-temporal window, resulting in a more detailed pictur of the environment. The state buffer is adjusted using the observations and all possible matches. Although using mapped features for localization enables to reach greater accuracy, this is only true if the map can be trusted. An approach using the post smoothing residuals has been developed to detect changes and either mitigate or reject the affected features

Les entreprises multinationales ou transnationales, dont le nombre ne cesse d’augmenter, présentent la particularité d’avoir des salariés présents sur les différents continents, travaillant avec des rythmes et des cultures différentes. Dans le cadre des activités des entreprises, de plus en plus de salariés sont amenés à travailler en équipe multiculturelle et délocalisée. Ces mêmes entreprises sont à la recherche des meilleures performances opérationnelles et le déploiement de la démarche Lean est un levier reconnu d’obtention des meilleures performances de manière pérenne et ce depuis des dizaines d’années. En parallèle, depuis le développement d’internet et des nouvelles technologies, de nouveaux outils deviennent disponibles pour collecter et analyser les données ou encore pour produire. Au sein des entreprises et alors que les impacts sont souvent traités de manière séparés, c’est bien de manière systémique et en même temps qu’interagissent les dimensions culturelles, le déploiement du Lean et la mise en œuvre des outils liés à l’ère numérique. Dans un soucis ultime performance pérenne, c’est bien l’efficacité du système dans sa globalité dont il est question.

More and more employees are required to work in multicultural and remote teams as part of their business activities. These same companies are looking for the best operational performance and the deployment of the Lean approach is a recognised lever for obtaining the best performance in a sustainable manner and has been for decades. In parallel, since the development of the Internet and digital technologies, new tools have become avaible to collect and analyse data or to manufacture. Within companies, while the impacts are often processed separately, it is indeed in a systemic way and at the same time that the cultural dimensions, the deployment of Lean and the implementation of tools linked to the digital era. With the ultimate aim of sustainable performance it is the efficiency of the system as a whole that is at stake. This thesis proposes to review of industrial situations, and to propose an support for the evaluation and consistent implementation of all three elements i.e culture, Lean and digitalization

Ces travaux de thèse portent sur le développement et la gestion des Systèmes Produit-Service (ou Product-Service Systems, PSS) automobiles. Ces nouvelles offres intégrées de produits et services comportent des spécificités qui obligent à dépasser les démarches de développement des produits historiques considérés. Dans un état de l’art, ces travaux s’intéressent aux cadres méthodologiques pour le développement des PSS. Le premier niveau de ces cadres, focalisé sur les approches d’ingénierie, porte sur le Service Lifecycle Management (SLM) et son interaction avec le Product Lifecycle Management (PLM). Le deuxième niveau du cadre méthodologique s’intéresse aux processus et méthodes de développement des systèmes et PSS. Le troisième niveau du cadre méthodologique s’intéresse aux modélisations de PSS. La proposition est définie à travers les trois niveaux du cadre méthodologique, en respect de 7 critères retenus pour l’ingénierie des PSS. Elle repose sur un schéma d’interaction entre le PLM et le SLM détaillé, supportant un processus de développement, intégrant les pratiques de gestion de la diversité et d’Ingénierie Système. L’ensemble est cohérent avec une modélisation des PSS intégrant les architectures système, et basé sur le FBS et le triplet Result-Ressource-Process essentiels à la description du service. Deux cas d’étude ont permis d’expérimenter cette proposition. Le premier cas d’étude, portant sur un PSS existant et maitrisé, s’est traduit en la spécification d’un outil d’amélioration de la qualité du service. Le deuxième cas d’étude porte sur un PSS de diagnostic connecté et permet d’illustrer la proposition pour supporter son déploiement dans l’entrepriseThis research work is exploring the development and management of Product-Service Systems. These new integrated offers go along with specific issues which challenge the current product development strategies. Analyzing the academic literature on this matter, this work focuses on methodological frameworks for the development of PSS offers. The first level of these frameworks is about engineering approaches considers Service Lifecycle Management (SLM) and Product Lifecycle Management (PLM) interactions. The second level is about specific systems or PSS development processes and methods. The third and last level challenges the definitions of a PSS model. Fed by this review, this work provides a coherent proposal for PSS development across these three levels, qualified by 7 analysis criterias. On the first level, a detailed PLM-SLM interaction scheme is proposed. It supports a development process on the second level, alongside a PSS model based on FBS and result-resource-process triplet as a matter for service adequate description. This proposal has been experimented through two study cases. The first one, about an existing and mature PSS, enabled the development of a quality management tool. The second, about the development of a connected diagnostic PSS enabled to strengthen the illustration of the proposal for its adoption

Full textAbstract:
Friction is one of the key phenomena during the interaction of ice with offshore structures and ships, ice rafting and ridging processes, and the brittle compressive failure of ice. Therefore, knowledge of the ice friction laws and a better understanding of this phenomenon are needed for the design of safe and reliable offshore structures and successful operations in ice-infested waters. This thesis presents experimental studies on ice friction in the field and in the laboratory and can be divided into three parts: field study of ice friction and the effects of different parameters on the kinetic and static friction coefficients; investigation of geometrical stick-slip interaction between ice and stainless steel in small-scale laboratory tests; field investigation of the vertical ice forces exerted on isolated vertical piles frozen in a level sea due to changes in the water level. The first version of the experimental setup for the field tests to study ice friction was relatively simple and was used only in 2010. Significant modifications and improvements were made to the setup in 2011 that allowed us to better control the test conditions (i.e., velocity, normal load). The available range of sliding velocities (between 6 mm s-1 and 43 mm s-1) did not cover the whole range of our interest. Therefore, a new pulling mechanism was introduced in the tests in 2012 that allowed us to extend the sliding range up to 110 mm s-1. The field experiments were conducted with first year sea ice in the Barents Sea and in fjords at Spitsbergen during three springs (2010-2012). In September of 2012, the ice friction tests were performed with multiyear sea ice northeast of Greenland. Most of the tests were performed to investigate the friction between sea ice and sea ice, while the rest were to study the friction between sea ice and corroded steel. The aim of the study was to survey the most important factors that affect ice friction in field conditions and to determine whether the existing friction models correctly predict the dependences observed in the field tests. The effects of the sliding velocity (6 mm s-1to 105 mm s-1), air temperatures (-2°C to -20°C), normal load (300 N to 2000 N), presence of sea water in the interface, and ice grain orientation with respect to the sliding direction on the friction coefficient were investigated. The effect of the hold time on the static friction coefficient was also studied. The test campaigns showed that ice surface roughness is likely to be the most important parameter in determining the friction coefficient. Repeated sliding over the same track led to surface polishing and decreased the kinetic friction coefficient from 0.48 to 0.05. When sliding occurs between unsmoothed surfaces, the friction coefficient was found to be independent of the sliding velocity. As the contacting surfaces become smoother, the kinetic friction coefficient begins to depend on the velocity, as predicted by existing ice friction models. Some attempts were made to characterise ice surface irregularities and real contact area using two techniques: 1) the production of an ice surface cast and its further analysis using an optical microscope and 2) measurements of the pressure distribution and real contact area using tactile sensors. The static friction coefficient increases logarithmically with the hold time and changes from approximately 0.6 at 5 s to 1.26 at 960 s. The small-scale laboratory studies on the stick-slip interaction between ice and stainless steel were performed at the University Centre in Svalbard (UNIS). A specially designed device allowed us to study the effect of well controlled steel surface roughness on the interaction between ice and steel under various test conditions. The effects of the relative sliding rate (1.67 × 10-6 m s-1 to 0.83 × 10-3 m s-1), temperature (-5°C to -25°C) and applied constant pushing force were also investigated. Stick-slip interaction was always observed in the tests on samples with an arithmetic average roughness (Ra) between 2 μm and 15 μm. Both steady state sliding and stick-slip were observed in the tests on samples with the lowest (Ra = 2 μm) and the highest (Ra = 25.2 μm) roughness. The slip distance was found to be equal to the mean pitch profile (mean profile wavelength) for all velocities studied. The elasticity of the ice was found to be an important factor in the stick-slip interaction. The field studies of the vertical ice forces exerted on isolated vertical piles frozen in the ice were performed in Svea, Spitsbergen, in March of 2010. Four different piles made of steel and aluminium were used in the experiments. The piles were pushed through the ice using a hydraulic jack. The first peak load measured in the tests is associated with the onset of the ice-pile relative movement. Because we always observed failure at or very near the ice-pile interface, the first peak load can be treated as the strength of adhesion or the cohesive failure of ice in the vicinity of the interface. Elastic plate theory was used to estimate theoretically the vertical forces exerted on a pile.

Full textAbstract:
The history of the development of the understanding of the statistical arrangement of hydrogen bonds in ice Ih and the discovery of the transition at 72 K to the ordered phase, ice XI, catalysed by alkali hydroxide doping, is reviewed. Possible ordered arrangements of hydrogen bonds are discussed and enumerated. A theory is presented relating the entropy and permittivity of partially ordered ice to the degree of order. The apparatus developed for dielectric experiments on KOH-doped ice is described. The results of such measurements for polycrystalline specimens and one single crystal are presented. Measurements above the transition reveal that the main charge carriers are OH\(^-\) ions, with a temperature-independent mobility of approximately 10\(^-\)\(^1\)\(^0\) m\(^2\) v\(^-\)\(^1\) s\(^-\)\(^1\). The transformation to the ordered phase starts when the sample is cooled below about 65 K, and once started can be speeded up by heating the sample to 67-70 K: the static permittivity and the a.c. conductivity slowly decrease. Neutron powder diffraction experiments were performed on HRDP at ISIS. After one unsuccessful experiment, dielectric measurements on powder samples showed the importance of excluding CO\(_2\) during preparation. In a second experiment the structure of ice XI was confirmed and the lattice parameters determined for the first time.

Romanen ”Is” utspelar sig i en fiktiv framtid och skildrar ett Sverige i svallvågorna avklimatförändringarna. Landet styrs av auktoritära högerpartier som har infört strikt kontrollpå befolkningstillväxten genom att unga män steriliseras efter att ha donerat spermaoch senare i livet får ansöka om att skaffa barn.Inom ramen för det här arbetet skildras samhället ur två perspektiv:1. Chinua kommer som flykting till Sverige och försöker starta ett nytt liv, men möterhårt motstånd från både samhällsapparaten och befolkningen. I desperation tvingashan sälja sin kropp, eller snarare sina spermier, till barnlösa kvinnor.2. I det inhägnade samhället Gränna bor Arwen och Viggo. De har fyra barn och ärbåda högt uppsatta i samhällsadministrationen och näringslivet. Arwen är den mest karriärmässigtdrivna, medan Viggo känner sig mer utanför. Skillnaderna mellan dem växeri takt med att samhället radikaliseras och de driver sakta isär, samtidigt som de vinnläggersig om att upprätthålla en polerad fasad.Syftet är att skildra ett framtida Sverige ur flera perspektiv så att möjliga svagheteroch styrkor visas upp. Chinuas perspektiv utgår från positionen ”ute, vill in”, en personsom utan eget förskyllande befinner sig utanför gemenskapen och kämpar för att bli endel av den. Chinua har tidigare försökt hitta en plats i andra europeiska länder, menmisslyckats och därför tagit sig vidare till Sverige. Arwen och Viggo-perspektivet äristället ”inne, vill vara kvar”, vilket ger möjlighet att gestalta den styrande delen av samhället,där de som passar in och tror på systemet lever.Planen är att i framtiden utöka romanen med ytterligare två perspektiv: ett om detbarndrömmande paret Jani och Dani, som får avslag på sin ansökan om att skaffa barn(också ett ”inne, vill vara kvar”-perspektiv, men underifrån); ett om de som valt att lämnadet nya Sverige och försöka bygga en alternativ gemenskap längre norrut (”ute, villvara ute”). Inom de respektive perspektiven är det också meningen att det ska finnas nyanseroch glidningar, och centrala personer kommer att skifta tillhörighet.Till planen hör också att vidareutveckla världsbygget med centrala frågor som temperaturhöjningoch havsnivåhöjning och deras bredare konsekvenser, samt att utforskaframtida teknisk utveckling och dess effekter på samhället och hur människor umgås.

Full textAbstract:
Safe winter navigation is a hot topic. Not only is the traffic density increasing but theenvironmental considerations are also getting bigger. An oil leakage from a big oiltanker can be of catastrophic proportions in the wrong area and more trafficincreases the risk of an accident. A project that aims for safer winter navigation isSafeWIN. The aim of this project is to develop a forecasting system for compressiveice and thus make winter navigation safer.This thesis is part of above mentioned project and aims to investigate what influenceice compression and ice class has on winter navigation. Vessels are exclusivelyAFRAMAX size tankers sailing on Primorsk in the Gulf of Finland during 2006. Transitdata comes from AIS tracks recorded by the Swedish Maritime Administration. Adatabase with tanker transits has been created and this information is the source forthe studies in this thesis. Included in the database are wind data, ice particulars andtransit information such as speed, and time at different activities during the transit.Average values for a transit has been investigated for comparison and to get a pictureof an average transit.Velocity, waiting time and time with assisting icebreaker are parameters that arebelieved to show how a tanker performs in winter navigation. These parameters arecompared with ice compression and ice class separately to see if there is acorrelation. Ice compression has also been investigated for correlation towards windforce to see if stronger wind generates stronger compression.Using the velocity in different ice compressions an estimate of ice resistance that stemfrom ice compression has been extracted by means of Lindqvist’s formula.

indispensáveis a uma abordagem de data-driven, escolhida
para caracterizar os dados obtidos. Tornou-se necessário
enquadrar o trabalho no âmbito do Inglês para Fins Específicos
(IFE), já que o Inglês para Fins Ocupacionais (IFO) era uma
vertente recente do IFE, sobre a qual não havia literatura
substancial. Assim, investigámos o IFE/IFO no mundo (cap. II),
em Portugal: no Ensino Secundário (ES) e no Ensino Superior
(ESup), no contexto (cap. I). Analisámos as taxonomias de
erros lexicais encontradas na literatura (cap. IV) e as
Estratégias de Aprendizagem (EA) subjacentes à aquisição do
vocabulário cap. III). Queríamos comparar os nossos resultados
com os apresentados na literatura para verificar se havia a

Similar difficulties had already been noticed by some teachers of English from other schools, namely the Accountancy and Administration Institutes of Aveiro, Coimbra and Oporto. On the other hand, a brief overview of existing literature revealed a relative shortage of studies on lexicon, and indeed none could be found on the specific area of lexical errors in BE. Given both the perceived difficulties experienced by my students and the lack of relevant studies on the subject, we decided to investigate the possible causes for this state of affairs. The present study will hopefully be useful to those who face similar difficulties, as it can be used both as a working tool and as a source of further research. The corpus of different types of lexical errors presented in this study resulted from the use of both quantitative and qualitative data collection methods. The data were gathered through questionnaires from students, teachers, educational institutions and enterprises and then analysed through descriptive statistics. Thus, the approach folloed is a data-driven one. The whole study is framed within the general field of English for Specific Purposes (ESP), as English for Occupational Purposes (EOP) is a relatively recent sub-branch of the former and so there is no substancial body of literature available. We describe ESP and EOP in the context of Portuguese secondery and higher education (Chap. 1), and then around the world (Chap. II). In Chapter IIIl, we analyse the learning strategies that underlie the acquisition of vocabulary. In Chapter IV, different taxonomies for lexical are discussed, and a comparaison between the data of this study and those presented in the literature is then drawn. Finally, we suggest practical measures to help students overcome difficulties in acquiring specific vocabulry (Chap. VII). Some of them are presented in detail in Appendix III, namely the organisation of a glossary of Accountancy, Administration and Auditing terms. We also include examples of classroom tasks for the learning/teaching of Business English and specialised translation.
El punto de partida para nuestro trabajo tuvo como origen las dificultades sentidas por nuestros alumnos de los Cursos de Contabilidad y Administración (CCA) en el reconocimiento y el uso del léxico específico del Inglés Empresarial/de los Negocios (IE/IN) al nível de la produción escrita. Una dificultad como esta ya habia sido percibida por los professores de Lengua Inglesa (LI) del CCA de los Institutos Superiores de Contabilidad y Administración (ISCAS) de Aveiro, Coimbra y Porto. También porque habia un numero muy reduzido de estudios sobre el léxico y ningun que conoceramos sobre vocabulário en IE/IN y aún menos sobre el análisis de los errores lexicales en ese domínio. La confluencia de todas estas circunstancias nos han motivado a la execución del presente estudio, destinado a todos aquellos que necessitan superar dificultades, utilizandolo como hierramienta de trabajo y fuente para otras investigaciones. Aprovechando las potencialidades y las ventajas de métodos qualitativos y quantitativos sustenida en una estadística descriptiva, construimos el corpus de análisis - los tipos de errores lexicales, completados por enquestas a los alumnos, professores, instituciones y empresas que irian figurar como plus valias indispensables para se hacer un abordaje de data-driven elegida para caracterizar los datos obtenidos. En esto sentido ha sido necessário inserir el corpus en el ambito del Inglés para Fines Específicos (IFE), una vez que el Inglés para Fines Ocupacionales (IFO) era una variable reciente del IFE sobre la qual habia literatura insuficiente para echar la mano. Asi investigamos el IFE/IFO en el mundo (cap.II) en Portugal , en su entorno secundário y terciário (cap.I) .Habemos analisado las classificaciones de los errores lexicales encontrados en la literatura (cap.

Además tuvimos que considerar medidas para mejorar esas dificuldades (cap.VII).

Le point de départ de notre travail a son origine dans les difficultés de nos élèves du Cours de Contabilité et Administration (CCA), dans la reconnaissance et utilisation du léxique spécifique de l' Anglais des Affaires (AF) au niveau de la production écrite. Les professeurs de Langue Anglaise des Instituts Supérieurs de Contabilité et Administration (ISCAS) d' Aveiro, Coimbra et Porto avaient déjà remarqué ce problème. En outre, il y avait très peu d' investigation à propos du léxique. On ne connaissait aucune sur le vocabulaire de l' AF. La confluence de ces constatations nous a motivé à conduire cette étude, concernant ceux qui ont besoin de dépasser des difficultés, comme outil de travail et comme source pour d' autres investigations. On a profité des potencialités et les avantages de méthodes qualitatives et quantitatives, appuyées sur une statistique descriptive. On a construit le corpus d' analyse - les types d' erreurs lexicales, complétés avec des enquêtes aux élèves, aux professeurs, aux institutions et aux entreprises, qui iraient constituer des surplus indispensables à un abordage de data-driven choisi pour charactérizer les données obtenues. Il est devenu necéssaire encadrer ce travail comme appartenant à l´Anglais Spécifique (AS) une foi que l' Anglais Professionel (AP) c´était une branche récente de l´ AS dont la littérature était insuffisante. Cette recherche a été effectuée au niveau mondial, voulant savoir aussi l' expression de l' AF au Portugal aux différents niveaux de l' enseignement: secondaire et tertiaire (chap. I). Il a fallu analyser les Taxonomies des Erreurs Lexicales trouvées dans la littérature (chap. IV) ainsi que les stratégies d' Apprentissage (SA) pour l' acquisition du vocabulaire (chap. III) afin de comparer les résultats obtenus avec ceux présentés dans la littérature et vérifier s' il y aurait des analogies ou des différences. Ensuite, des mésures on été considérées pour améliorer ces difficultés (chap. VII et annexe III). Une de ces mésures sera l' élargissement d' un glossaire de Contabilité et Administration. Nous voulons aussi faire des exercises pour nos classes, soit au niveau de l' enseignement/apprentissage de l' AS/AP, soit de la traduction spécifique.
