Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, 2008. Includes bibliographical references (leaves 93-100). Back in 2003, Blogs as well as wikis started the Web 2.0 frenzy with online community networks and user generated content. Web 2.0 has recently cooled down, but it may have started a new era. The purpose of this paper is to explore the blogonomics - the business, as well as social, changes blogs have brought to us. It applies system thinking to analyze blogs, from blog elements (forms) to blog systems, and then to major components in the blog ecosystem. This paper focuses on the returns on blogs (ROB), mainly the business impact. Blog marketing, including word-of-mouth marketing (WOMM) and blog ads, has been discussed extensively along with the business models that can monetize blogs. It also proposes to use blogs as innovative tools for collaboration and content management. This paper primarily targets companies interested in the benefit from blogs. Furthermore, it hopes to explore a few innovative blog business models for entrepreneurs and serve anyone who is genuinely interested in blogs and Web 2.0. by Ching Q. Guo. S.M.

Abstract:

Användningen av ledningsbloggar som verktyg för internkommunikation har ökat, samtidigt som forskning visar att högsta ledningen i många organisationer ser brister i sin kommunikativa förmåga. Kombinationen av ett begränsat forskningsunderlag kring fenomenet ledningsblogg och betydelsen av ett kontinuerligt och framgångsrikt förbättringsarbete ger denna uppsats sitt syfte: Att bidra med kunskapsutveckling kring hur högsta ledningen kan stimulera en organisation mot en högre grad av ständiga förbättringar genom att kommunicera internt via en blogg. En kvalitativ studie utfördes i form av en fallstudie på en organisation där ständiga förbättringar ingår i strategin och utgör en del av visionen och 2016 års mål. Intervjuer genomfördes med chefer på lägsta nivå kring deras upplevelse av den befintliga ledningsbloggen. Resultatet från intervjuerna analyserades mot befintlig teori samt existerande blogginlägg. Analysen utgick från Koenig och Schlaegels (2014) sex teman som beskriver hur bloggens designkarakteristika påverkar läsarens upplevelse: Innehållsvärde, Underhållsvärde, Styrning/Förvaltning, Användbarhet, Interaktion och Marknadsföringsbudskap. Baserat på dessa sex teman har två fiskbensdiagram tagits fram positiva och negativa upplevelser redovisas. Dessa upplevelser kan påverka attityden och därmed beteendet och på så sätt utgöra stimulans respektive hinder i arbetet mot en högre grad av ständiga förbättringar. Resultatet visar att rätt använd kan en intern ledningsblogg vara ett effektivt verktyg för att påverka organisationskulturen, men det krävs kunskap om retorik för att inte riskera att bloggen blir mer av ett hinder än ett verktyg som stimulerar. För att uppnå positiv påverkan behöver mottagaren ges en upplevelse av såväl nytta, enkelhet som nöje och resultatet visar också att genom att fokusera på mottagaren kan olika typer av kommunikationsbarriärer övervinnas. Ett antal aspekter som bör prägla bloggen för att stimulera till ständiga förbättringar har identifierats, och även ett antal aspekter som kan utgöra hinder. Analytisk generalisering av dessa slutsatser bidrar till kunskapsutveckling inom området. Denna uppsats har resulterat i bekräftelse av tidigare forskning, konkreta användarråd samt förslag på vidare forskning för att ytterligare reducera det gap som finns kring detta område. The use of management blogs as a tool for internal communication has increased, at the same time research shows that top management in many organizations sees shortcomings in their own communicative ability. The combination of limited research about the phenomenon of management blogs and the importance of a continuous and successful improvement work gives this study it´s purpose: To contribute with knowledge about how top management can stimulate an organization towards a higher degree of continuous improvements by communicating internal through a blog. A qualitative study was conducted as a case study in an organization where continuous improvements are part of the strategy and forms part of the vision and the objectives of 2016. Interviews were performed with managers at the lowest level regarding their experience of the management blog in the organization. The results of the interviews were analyzed against existing theory and blog posts. The analysis was based on Koenig and Schlaegel's (2014) six themes describing how the blog's design characteristics affect the reader's experience: Content Value, Maintenance Value, Management / Management, Usability, Interaction and Marketing. Based on these six themes, two fishbone diagrams have been produced that report positive and negative experiences. These experiences can affect the attitude and hence behavior and thus constitute the stimulus's respective barriers in the work towards a higher degree of continuous improvement. The result shows that properly used, an internal management blog can be an effective tool for influencing organizational culture, but knowledge of rhetoric is required to avoid risking blogging becoming more of a barrier than a tool that stimulates. To achieve positive impact, the recipient needs experience of both usefulness, simplicity and pleasure and the result also shows that by focusing on the recipient, different types of communication barriers can be overcome. A number of aspects that should characterize the blog to stimulate continuous improvements have been identified, as well as a number of issues that may constitute obstacles. Analytical generalization of these conclusions contributes to knowledge development in the area. This study has resulted in confirmation of previous research, concrete user advice and suggestions for further research to further reduce the gap that exists around this area. 2017-06-28

Abstract:

This research study analyzed the sources of nutrition blog information as measured by frequency and type of sources used by nutrition bloggers. Since the use of online resources for finding health information has become more prevalent, it is important to further research the topic for the purpose of better understanding how our nutrition agenda is set by nutrition bloggers. Focusing on 20 nutrition blogs, the study content analyzed 3,156 blog posts during a one-year period from September 1, 2011 to August 31, 2012, yielding 5,263 sources. Additionally, in-depth interviews were conducted with the writers of all 20 blogs in July 2012. The findings showed that (1) nutrition bloggers are sourcing half of the time, (2) nutrition bloggers are citing a variety of sources that include both credible and less credible sources, (3) nutrition bloggers are finding and choosing sources in various ways that include both credible and less credible methods, and (4) there is no difference in the sources selected by men and women bloggers. Overall, this study shows the need to create best practices for blog sourcing that serve as guidelines for both bloggers and readers, with emphasis on guidelines for source frequency and credibility of sources.

Among the goals, I try to identify through the web interface analysis, while visual image, as shown blog design Rio Etc by proposing a street fashion concept on the Internet. I seek to do so, to express how is the formation of a Technology Interactive Design; attentive to fashion's image as a mediating element between man and culture in the digital environment and point out the street-style as contemporary phenomenon in tribalisation of subjects inserted in the group that plans and produces photographic images to the blog (main content of posts Rio Etc) and portrays the street fashion as a lifestyle, and spread this idea over the internet through the blog tool. Based on this, the Comprehensive Sociology appears to support, in the Interdisciplinary methodology, the unfolding of man as a social being who participates in the cyberculture as a producer designs and puts them at the disposal of Internet users. In this qualitative research, we present an overview of images collected in Rio Etc blog over two years of research, focused on illustrative presentation of archived records in the blog since 2007 (rise of the Rio electronic diary), incorporating the text images that best could set the observed phenomena. I emphasize that the concept of street-style produced by Rio Etc does not include the capital in its territorial and economic diversity, but rather part of a cutout on the street fashion that moves specifically for the south of the city. A pesquisa investiga, com base na din?mica social moderna, a constru??o do conceito de Desenho Tecnol?gico Interativo do blog Rio Etc, com a finalidade de ampliar as concep??es acerca do desenho enquanto imagem que transmite, comunica e pode ser constantemente ressignificado por meio de uma perspectiva Interdisciplinar, buscando reconhecer o desenho como projeto, prop?sito e intento, logo, est? para al?m da sua instrumentalidade e representa??o da a??o humana atrav?s de um l?pis e uma folha de papel. Entre os objetivos, procuro identificar atrav?s da an?lise da interface web, enquanto imagem visual, como se apresenta o desenho do blog Rio Etc ao propor um conceito de moda de rua na internet. Busco, para isso, expressar como se d? a forma??o de um Desenho Tecnol?gico Interativo; atento para a imagem de moda como elemento mediador entre o homem e a cultura no meio digital e aponto o street-style como fen?meno contempor?neo na tribaliza??o dos sujeitos inseridos no grupo que planeja e produz imagens fotogr?ficas para o blog (principal conte?dos das postagens do Rio Etc) e retrata a moda de rua como estilo de vida, al?m de difundir esta ideia atrav?s da internet por meio da ferramenta blog. Com base nisso, a Sociologia Compreensiva aparece para sustentar, na metodologia Interdisciplinar, os desdobramentos do homem enquanto ser social que participa da cibercultura como produtor de des?gnios e os coloca ? disposi??o dos internautas. Nesta pesquisa qualitativa, apresento um apanhado de imagens coletadas no blog Rio Etc ao longo de dois anos de pesquisa, centrada na apresenta??o ilustrativa de registros arquivados no blog desde o ano de 2007 (surgimento do di?rio eletr?nico carioca), incorporando ao texto imagens que melhor pudessem configurar os fen?menos observados. Destaco que o conceito de street-style produzido pelo Rio Etc n?o contempla a capital na sua diversidade territorial e econ?mica, mas sim, parte de um recorte sobre a moda de rua que transita especificamente pela Zona Sul da cidade.

This research intends to review the main basic concepts about blogs, to indicate common points to the different platform applications. The first chapter will explore blogs under three prisms: structural, explaining the tools that the available services nowadays offer; practical, exploring which habits come from the appropriation of the tools; and the conversations, with blogs hosting dialogues highly fragmented and infinitely expansible. The second chapter will retake the classification of the blogs as a genre to indicate the necessity of seeing them as language, presenting suggestions for a model of a more precise and discerning definition. The third chapter will explore the development of the blogs in United States and in Brazil, in a comparison that intends to highlight common points and differences in their development in both countries. The fourth chapter will analyze three Brazilian case studies and it is focused in their capacities to attract and interact with their communities A popularização dos blogues do seu surgimento em 1996 até os dias de hoje, atraindo perfis de usuários além dos entusiastas e profissionais de tecnologia, nos apresenta novos tipos de aplicações da plataforma que extrapolam as definições iniciais de filtros de links ou diários pessoais na internet. Esta pesquisa pretende passar em revisão os principais conceitos básicos sobre os blogues, para indicar pontos comuns às diferentes aplicações da plataforma.

Abstract:

The current economic situation in the U.S. has demanded budget cuts in all areas of American life, including education. Faced with these unprecedented cuts, many arts programs are losing their funding. Many art educators are finding it a challenge to provide art education without compromising the quality of the curriculum and program. Through a comparative analysis of materials and fundraisers and a document analysis of money saving tips, strategies are suggested for art teachers to save and find money.

Abstract:

Träningshysterin är på sin topp just nu. Idag är träning någonting många prioriterar för att må bra. Av intensivt fysiskt arbete, som till exempel hård styrketräning eller crossfit får man snabbt valkar och sår i händerna. Det finns en uppsjö av handskar designade för olika typer av träning på marknaden, trots detta används handskarna inte alls av många. Orsaken är dels att handskydd har fått en stämpel som ”fånigt” i träningssamanhang och dels upplevs handskar som ett hinder snarare än ett skyddsmedel. Detta eftersom gymhandskar upplevs klumpiga och försämrar greppet. Begreppet design handlar inte endast om utseende och estetik, utan innefattar även funktionalitet. God design är när man uppfyller ett behov hos användarna både vad gäller utseende och funktion. Genom ett antal kvantitativa intervjuer, enkäter, tester, undersökningar samt observationer har data samlats in för att förstå målgruppens behov och krav. Dessa behov och krav har sedan fått stå i fokus genom hela designprocessen för att komma fram till ett slutkoncept som skyddar händerna på ett innovativt, diskret och smidigt sätt.

Abstract:

This thesis offers an assessment design for collaborative learning, utilisation of blended learning support through current communication technologies and highlights the crucial role of the tutor. The thesis designed and tested a theoretical framework which encompassed an active learning environment and resulted in the development of the shamrock conceptual framework. To test the theoretical framework, clarify the role of the tutor and the impact on the learner experience two studies were undertaken using pedagogical models that combined the concepts of learner-centric, sociocultural and dialogic perspectives on collaborative learning and technology in meeting the needs of learners in the 21st Century. In the first study, the role of the tutor was found to be crucial in setting, implementing and guiding learners using the assessment design as part of a social constructivist pedagogical practice. The pedagogical approach adopted was to blend face-to-face and Wiki learning experiences and was found to promote learner ownership, engagement and the fostering of a learning community. The second study validated the first and provided additional asynchronous technology experiences in addition to the Wiki blend in the assessment design. Study 2 examined the role of the tutor and the learner whilst using current technologies comprising podcasts and video and a Wiki in the collaborative experience. Findings showed that the Wiki supported community and collaborative aspects of a sociocultural practice whilst learners were engaged in authentic learning activities and led to a well supported learning environment. The importance of technology design and use to accommodate collaborative and community aspects was found to be an essential component. It was found that technology is not simply an add-on but rather needs to be planned and considered purposefully by both tutors and learners when used in a blend to supplement learning on campus as part of an assessment design in higher education. This study has shown that, for this to happen, academics need to be provided with the appropriate support, knowledge and skills required in developing a blended learning experience using a Wiki supplemented by class contact on campus as part of an assessment design.

Abstract:

Modebloggar är ett fenomen som har fått både ris och ros. Medans en del avfärdar det så har många företag insett fördelarna med att använda sig utav bloggar. De kan på ett billigt sätt få reklam som träffar exakt rätt målgrupp. Att bloggare även skriver om företag av egen vilja kan ge företag extra marknadsföring, om det är en positiv text. När en stor bloggare rekommenderar ett plagg i sin blogg tar det inte lång tid innan det är slut i butik. Att modebloggare har fått en viss makt över sina läsares konsumtionsvanor är något som inte längre går att förneka. Att plagg som blir ombloggade tar slut i butik håller både konsumenterna och butikerna med om. I åldersgruppen 15-25 år läser 68 % av tjejerna modebloggar och många läser flera stycken varje dag. Det har diskuterats mycket hurvida det påverkar modebloggares förtroende när de tipsar om de gratisprodukter de får. Bloggarna själva säger att de aldrig skulle tipsa om något de själv inte gillar och de konsumenter som tillfrågats i enkätundersökningen är inte särskilt påverkade av detta. Har man fastnat för en blogg stannar man kvar och litar på att bloggaren vet vad den pratar om. Program: Butikschefsutbildningen

Abstract:

This is a personal project about a fed-up woman who sits down on the chair by the pottery wheel simply because she craves it. It is about conducting a non-result oriented design process. A process where the making, the closeness between the mind and hand, is both the research and mediation. It is a project that acknowledges the potential care has in relation to design, while it's dealing with the controversial aspects of a woman caring for herself. The project is a snap, a feminist snap, represented and materialized through the objects of clay. Where a collapsed bowl, a blob, becomes a materialized revolt against everything women are being told to endure. It is a project that brings design and poetry together. Aiming to explore how objects can gain agency and be in dialogue with society. How objects can materialize both the resistance against, and the result of, the patriarchal structure.

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Design e Expressão Gráfica Made available in DSpace on 2013-06-25T22:40:46Z (GMT). No. of bitstreams: 1 309925.pdf: 48242503 bytes, checksum: dc4364e6d625e0f8d7094f5d9d6bcae7 (MD5) Na década de 1990, inicia-se a popularização da "World Wide Web" (rede mundial de computadores) conhecida como Internet, conectando pessoas, popularizando culturas e aproximando distâncias. Essa realidade coloca à disposição inúmeros serviços e ferramentas, como os diários digitais - Blogs, que possuem estruturas dinâmicas de atualização de textos, fotos, vídeos, músicas, gravações de áudio e demais conteúdos de forma colaborativa, por um ou vários usuários dependendo da sua política; os blogs podem dispensar o conhecimento de programação por parte do seu publicador, levando a um questionamento a respeito de quais ferramentas gráficovisuais são aplicadas nas interfaces. Para fazer frente a essa preocupação, o desenvolvimento de projetos de interface deve ter como base princípios de design, boa usabilidade e interação homemmáquina, conceitos de estudo para essa pesquisa. Este projeto pesquisa os fatores de design que propiciam melhor desempenho nas interfaces de blogs voltados ao ensino. Para isso, será realizado um estudo em blogs disponibilizados por professores do curso de design da Universidade da Região de Joinville # Univille. Tal estudo fará uso da utilização de questionários aplicados aos usuários para identificar os elementos mais funcionais e atrativos das interfaces; de grupo de foco para compreender dos professores suas escolhas na construção das interfaces e de uma avaliação heurística para obter um comparativo dos bons princípios de projetos de webdesign com as características aplicadas atualmente nas interfaces publicadas pelos professores. In the 1990s, begins the popularization of the "World Wide Web" (world wide web) known as the Internet, connecting people, popularizing cultures and approaching distances. This reality provides numerous services and tools, such as digital diaries - Blogs, that have dynamic structures to update texts, photos, videos, music, audio and other content collaboratively, by one or more users depending on their policy; blogs can dispense programming knowledge by his publisher, leading to questions about which graphic-visual tools are applied on interfaces. To justify this concern, the development of interface project should be based on principles of design, good usability and human-computer interaction, concepts of study for this research. This project researches the design factors that provide better performance at the interfaces of blogs geared to teaching. This will be a study in blogs available for teachers design course at the University of Joinville Region - Univille. This study will make use of the questionnaires for users to identify the elements of the most functional and attractive interfaces; focus group of teachers to understand their choices in the construction of interfaces and a heuristic evaluation to get a good comparison of the design principles web design with the features currently used by teachers in the published interfaces.

Abstract:

Ce travail porte sur la conception d'un amplificateur de puissance à 79 GHz et la co-intégration de l'amplificateur de puissance et l'antenne en technologie silicium SiGe. L'objectif de la thèse est de développer un module radiofréquence à l'émission pour des applications radar à 79 GHz. Ce module sera composé d'un amplificateur de puissance, d'une antenne et du circuit d'adaptation PA/Antenne. L'inter-étage entre le PA et l'antenne est une source supplémentaire d'atténuation du signal, d‟autant plus rédhibitoire en technologie intégrée pour des fréquences aussi élevées.

Plus précisément, il convient de dimensionner l'antenne afin qu'elle présente a la sortie du PA l'impédance optimale que requiert son rendement en puissance maximum This work focuses on the design of a power amplifier (PA) at 79 GHz and the co-integration of the PA and the antenna on SiGe technology. The objective of this thesis is to develop a RF front-end block for radar applications at 79 GHz. This block is compound of a power amplifier, antenna and PA/Antenna inter-stage matching. The inter-stage between the PA and the antenna adds supplementary losses in the global performances, especially prohibitive in integrated technology for high frequencies. The co-design of the antenna and the PA allows to suppress the traditional inter-stage impedance matching between these two blocks. More specifically, it is suitable to design the antenna with the appropriate output impedance of the PA which gives optimal performances for maximum power and efficiency

Abstract:

The purpose of this research is twofold. Firstly, this research aims to investigate whether the design preferences of bloggers in selected countries from different cultural backgrounds are influenced by national culture traits. The investigation involves two categories of blogs selected within a country where the bloggers share similar attributes such as language or geographical location. Secondly, simultaneously, this research intends to discover the possibility of the impact of group level influence on design preferences of bloggers who are linked together in a network through bloggers’ linkage or blogrolls. To achieve the said purposes, observations on both the global and local blogs of six selected countries are conducted using the content analysis method. This method allows this research to observe web pages and rate design preferences of bloggers via a coding system, similar to the method used to analyse documents or manuscripts to find common themes or keywords. A total of 612 blogs (306 global and 306 local) are observed for a period of nine months to identify cultural traits on design behaviour based on national culture indicators chosen from prominent literatures. To prevent a systematic error, an independent second observer was appointed and the results obtained are compared using a statistical methodology. In addition, translators were also engaged to verify that the translations are of a correct meaning and comprehension since blogs use various national languages on their web pages. The data were statistically tested using SPSS engaging in statistical analysis of frequency table, Cross-Tabulation and cluster analyses and MANOVA. Results shown that design preferences between both the global and local blogs in each country, has significant differences in most of the design indicators chosen. The findings indicate that the national culture influence on design preferences in linked networks of blogs is weakening indicating another type of influence might be in existence. The results also provide evidence that blogs in linked networks are statistically significant as a cluster or a group by themselves and are independent from one cluster to another. The research, however, studies only six countries from six different cultural dimensions. The inclusion of other countries, similar to or different from the countries under investigation, would be an added advantage. Furthermore, the use of only a single type of global blog provider (blogspot.com) in this research could be extended to other global blog providers such as wordpress.com to give fairer coverage of major and popular global blogs as well as providing a wider generalisation effect of the research findings.

Abstract:

In this paper we examine how young women present themselves on their weblogs. The main purpose of this study is to get their own opinions and thoughts about their own blogging, to see if we can find norms for how they present themselves and how the presentation online matches themselves offline. We put this in relation to information technologies, social software and Computer mediated communication, CMC. It´s also in our interest to see how the phenomenon of blogs, its role and methods of communication have changed and developed in the last few years, and whether there are differences in the way people use it according to age. The major finding is that, unlike previous research, the women in our study tend to be themselves in their weblogs and they do not manipulate their identities. They main use of their weblogs is as a space where they feel free to write what's on their mind, their thoughts and feelings and to inform their relatives about their everyday life, but also as a diary to remember their past and for self examination.

Cette thèse se compose de trois parties, chacune formée d'un chapitre de rappels et d'un chapitre contenant des "nouveautés". Dans la première partie, après des rappels sur la représentation du groupe symétrique, nous étudions certaines fonctions harmoniques associées à une représentation classique de Sn. Dans la deuxième partie, nous donnons une caractérisation de certains designs généralisés dans le cadre des schémas d'association. Les fonctions harmoniques de la première partie nous permettent de déduire un algorithme pour tester si une ensemble donné est un design. Enfin, dans la dernière partie, nous définissons pour les codes binaires des énumérateurs de poids harmoniques ; dans le cas des codes autoduaux nous établissons des résultats d'invariance, notamment une identité de type MacWilliams.

Abstract:

Dans cette thèse, nous nous intéressons à l’étude des chiffrements à flot basés sur l’utilisation de séquences algébriques. Plus précisément, nous utilisons dans notre approche la topologie π-adique et les automates linéaires. Dans un premier temps, nos travaux présentent des résultats généraux basés sur l’utilisation d’un anneau π-adique quelconque. Puis nous traitons deux cas particuliers : lorsque l’anneau considéré est l’anneau des séries formelles, et lorsque celui-ci est l’anneau des entiers N-adiques. Dans ces deux cas, nous nous intéressons particulièrement aux contraintes liées à l’implémentation de tels automates, d’un point de vue matériel et logiciel. Nous présentons ensuite comment il est possible d’améliorer la sécurité de chiffrements à flot basés sur des automates 2-adiques. Pour cela, nous appliquons nos travaux aux chiffrements à flot F-FCSR-H et X-FCSR-128. Enfin, nous présentons des travaux réalisés au cours de cette thèse dans le domaine des chiffrements par bloc et des fonctions de hachage. Ces travaux se fondent sur les propriétés intégrales des chiffrements par bloc, ainsi que sur les notions de distingueurs à clef connue et choisie. La combinaison de ces deux approches a été appliquée aux fonctions de hachage Hamsi-256, LANE- 256 et Grøstl-512, toutes trois candidates à la compétition SHA-3 In this thesis, we are interested in the study of stream ciphers based upon algebraic sequences. More precisely, our approach used π-adic topology and linear automata. First, general results based on π-adic ring are presented. Then we specify the ring considered. We focus on the ring of formal power series, and on the ring of N-adic integers. In both case, constraints of implementation are especially studied, for hardware and software purpose. Next, we present how these results may be used to enhance the security of stream ciphers based upon 2-adic automata. We focus on the stream ciphers F-FCSR-H and X-FCSR-128. In last part, this thesis deals with additional works in block ciphers and hash functions. These results are based upon integral properties of block ciphers, and upon known key and chosen key distinguishers. The combination of these properties and distinguishers have been applied to the hash functions Hamsi-256, LANE-256 and Grøstl-512, which are submitted to the SHA-3 competition

Abstract:

Le concept de metamatériaux est apparu au cours des années 2000 avec la réalisation de structures artificielles permettant une propagation non-conventionnelles des ondes électromagnétiques. La réponse électromagnétique des metamatériaux est liée à la présence d’éléments optiquement résonants, de dimensions inférieures aux longueurs d’onde d’excitation, arrangés dans une structure périodique prédéfinie.Afin de produire les structures géométriques inhérentes au design de metamatériaux, l’auto-assemblage des copolymères à blocs constitue une méthodologie émergente. En effet, les structures périodiques produites lors de la séparation de phase de ces matériaux peuvent être utilisées en tant que canevas pour la création de réseaux périodiques de nanoparticules. L’objectif principal de ces travaux de thèse a ainsi été de démontrer la validité de cette stratégie pour la réalisation, d’une manière simple et reproductible, d’une large gamme de nanostructures et de corréler les paramètres structuraux de ces réseaux de nanoparticules aux propriétés optiques.Une première démonstration de ce concept a été obtenue en utilisant un copolymère à blocs formant une structure lamellaire afin de réaliser des surfaces possédant des indices de réfraction élevés. La formation contrôlée de particules métalliques au sein de cette structure a permis de produire des surfaces décorées par ces nanoparticules, pour lesquelles une corrélation entre la teneur en or et l’indice de réfraction résultant a pu être établie. Ce concept a été poussé plus en avant en utilisant une gamme des copolymères à blocs de différentes masses molaires et formant une morphologie cylindrique. En effet, un contrôle accru des paramètres structuraux des réseaux de nanoparticules (diamètre et distance inter-particules) a permis la réalisation de metasurfaces aux propriétés optiques variées. Enfin la mise au point d’une stratégie d’auto-assemblage itérative nous a permis d’obtenir des metasurfaces au design complexe, avec notamment la production de surfaces décorées par des clusters bimétalliques ou des multicouches hybrides polymère/metal. Dans l’ensemble des cas, les surfaces décorées de nanoparticules ont été minutieusement caractérisées par des techniques de microscopie et de diffraction RX afin de mieux appréhender les propriétés optiques dérivées d’analyses d’ellipsométrie spectroscopique à angle variable The concept of metamaterials appeared in the years 2000 with the achievement of artificial structures enabling nonconventional propagation of electromagnetic waves. The electromagnetic response of metamaterials is based on the presence of optically resonant elements of sub-wavelength size and well-designed morphology and organization.In order to create controlled geometrical structures inherent to metamaterials design, block copolymer self-assembly constitutes an emerging strategy. Indeed, the periodic structures inherent to their segregation behavior can be used as scaffolds to create various regular or ordered nanoparticles arrays. The main objectives of this study is to demonstrate that block copolymer can indeed lead to a high level of control of a variety of designed nanostructures, in an easy and scalable method, and to correlate the structural parameters of the nanoparticles arrays and their optical properties.As a first demonstration, a lamellar-forming (poly(styrene)-block-poly(2-vinylpyridine) was used to create high refractive index surfaces. The selective and customizable metal incorporation within the out-of-plane lamellae produces azimuthally isotropic metallic nanostructures of defined geometries, for which a clear relationship between the gold content and the refractive index was established. Further studies were dedicated to the correlation between the geometrical parameters of the nanoparticles arrays and the optical properties through the macromolecular engineering of a series of cylinder-forming block copolymers having a wide range of molecular weights. Through this strategy, the particle diameter and the inter-particle distance were tuned leading to the production of metasurfaces with various optical characteristics. More complex metasurface designs were also obtained using a layer-by-layer self-assembly strategy, i.e. bimetallic raspberry nanoclusters or layered hybrid (metallic/polymer) structures. In all cases, the nanoparticles arrays were thoroughly analyzed using microscopy and small-angle X-ray scattering techniques in order to better apprehend the optical properties derived from variable-angle spectroscopic ellipsometry analysis

Este termo refere-se a um recurso criado para representar o processo de tagging, de atribuir palavras-chave aos conteúdos da web, frequentemente utilizado em blogs. Objetivamos, então, identificar os sentidos produzidos por blogueiros sobre tag clouds a respeito dos motivos de incorporação desse recurso nos blogs e dos padrões de utilização. Para a construção de dados, pesquisamos por posts que discutiram sobre a utilização de tag clouds, visando a identificação dos sentidos sobre os motivos de incorporação; e, por outro lado, para investigar os sentidos sobre os padrões de utilização, convidamos blogueiros para a participação de entrevistas sobre o tema. Encontramos que os sentidos produzidos sobre os motivos de incorporação são direcionados a comparações intrarecurso, entre tipos de tag clouds, e inter-recurso, entre tag clouds e outros recurso como lista de tags e menu. Em relação aos padrões de utilização identificamos que estes estiveram relacionados aos sistemas de informação hospedeiros dos blogs. No 'Blogger.com', tag clouds caracterizam-se como menus para navegação nas páginas pessoais e, em geral, os blogueiros optaram por utilizá-lo nos blogs, e, por outro lado, no 'Wordpress.com', os blogueiros, em sua maioria, não optaram por utilizar tag clouds em suas páginas, já que as tags criadas direcionam para a navegação no sistema de informação. Concluimos, então, que representar tags através de tag clouds no próprio blog significa utilizar esses dados parcialmente, isto é, considerando apenas seu aspecto individual. Contudo, ao representar o conjunto de tags de um sistema de informação em uma única tag clouds, prioriza-se o aspecto coletivo. Porém, as duas dimensões, individual e coletiva, não são excludentes e ao precisar optar por uma dessas, os blogueiros são afastados do que parece ser a característica e função diferenciadora de tags e tag clouds na atividade, isto é, a união entre informações individuais e coletivas, entre interesses e conhecimentos que falam sobre um sujeito e, ao mesmo tempo, sobre uma comunidade

Abstract:

En chirurgie contemporaine, la visualisation des données médicales joue un rôle crucial, sous forme d'images 2D ou 3D, aussi bien en pré-opératoires, qu'en per-opératoires où la stérilité doit y être préservée à tout instant. Un système d'interaction sans-contact, faciliterait grandement la preservation de la stérilité. Ici nous détaillons notre approche méthodologique pour concevoir un tel système. Le cas d'usage pratique pris en référence par notre travail est une opération de laparoscopie et le logiciel courament associé. Une analyse de la problématique, du cas d'usage et de sa contextualisation nous a permis d'élaborer une méthodologie, concrétisée en une phase exploratoire formalisée, et une phase expérimentale. Cette dernière, elle-même découpée en 2 temps: une étape visant des sujets “ tout-venants ” permettant d'extraire un vocabulaire d'intuitions génériques, ensuite affiné en utilisant les retours des sujets “ experts ” In modern surgery, the visualization of medical data plays a crucial role, in the form of 2D or 3D images, both in per-op and pre-op, where sterility must be preserved at all times. A touchless interaction system would greatly facilitate the preservation of sterility. Here we detail our methodological approach to design such a system. The practical use case referred to in our work is a laparoscopic operation and the case of use associated software. After analysizing the problem, the use case and its contextualization we developped a methodology, which was concretized in a formal exploratory phase and an experimental phase. The latter, itself divided into two stages: a stage aimed at "all-coming" subjects allowing us to extract a generic intuition vocabulary, which is then refined using feedback from "expert" subjects

Abstract:

The challenges found in three-dimensional platformer games heavily rely on the player’s ability to perceive depth and it is therefore crucial for them to feature shadows as they are an important depth cue for the human visual system. In this paper, we compare two different kinds of shadowing solutions, blob shadows and shadow-maps. Subjects split into two groups each played a differently shadowed version of a 3D platformer game prototype as well as a common, unshadowed version. The first group’s prototype featured blob shadows while the second group’s used shadowmaps. The players were asked to input their own proficiency level from one to five into the program. The data collected through in-prototype logging to a file hinted at shadowmaps being more desirable as the shadowmap group’s delta from shadowed to unshadowed playthrough was lower than the blob shadow group’s. However, this data featured a number of problems, such as low sample size, subjective evaluation of player proficiency in 3D platformer games and different distribution of proficiency in and across groups. Utmaningarna funna i tredimensionella platformsspel beror starkt på spelarens förmåga att uppfatta djup och det är därför avgörande för spelaren att ha skuggor eftersom de är en viktig antydan till djup för det mänskliga visuella systemet. I detta examensarbete jämför vi två olika typer av skuggningslösningar, “blob shadows” och “shadowmaps”. Försökspersonerna delades upp i två grupper, var och en spelade en annorlunda skuggad version av en prototyp för ett 3D-plattformsspel samt en ordinär, version utan skugga. Den första gruppens skuggor gjordes med “blob shadows” medan för den andra gruppen användes “shadowmaps”. Spelarna ombads att mata in sin egen kompetensnivå från ett till fem i programmet. Uppgifterna som samlats in via loggning i prototypen skrevs till en fil som antydde att “shadowmaps” var mer önskvärda eftersom “shadowmap”-gruppens delta från skuggad till icke-skuggad igenomspelning var lägre än skugga-gruppens. Dessa data innehöll emellertid ett antal problem, såsom låg provstorlek, subjektiv utvärdering av spelarens kunskaper i 3D-plattformsspel och olika spridning av kunskaper i och över grupper. Insikter för framtida forskning inkluderar skapandet av en objektiv ram för utvärdering för kunskaperna för spelarna såväl som förminskningen av prototypens omfattning.

Abstract:

Nitrification is the biological process whereby ammonia is converted first to nitrite by ammonia-oxidizing bacteria, and then the nitrite is subsequently converted to nitrate by nitrite-oxidizing bacteria. Ammonia and nitrite levels are closely monitored during treatment of wastewater due to their toxicity to other biological processes. Sybron Chemicals, Inc., is a company that manufactures a nitrifying bioaugmentation culture (1010N) that is used to enhance the naturally occurring levels of biological nitrification. The microbial population of the 1010N product has been examined using a combination of conventional bacteriological methods and modern molecular techniques, with the goal of developing nucleic acid probes that can be used to detect the product in an environmental sample. Small regions of the 16S rRNA genes of the bacteria in 1010N (and two new nitrifying enrichment cultures) were amplified via the polymerase chain reaction (PCR) and analyzed via temperature gradient gel electrophoresis (TGGE). TGGE is a procedure that allows for separation and visualization of individual PCR products that are the same size, based on differences in their sequence. Two of the predominant PCR products in 1010N were purified from the TGGE gel matrix, reamplified via PCR, and sequenced to allow for phylogenetic analysis and nucleic acid probe design. Coincidentally, two strains (NS500-9 and MPN2) that had been isolated from the 1010N mixed consortium and grown in pure culture were found, via TGGE, to have identical 16S rRNA sequences to the PCR products under investigation. Nearly the full-length 16S rRNA genes from these two organisms were PCR amplified, cloned, and sequenced in order to provide a basis for more accurate phylogenetic analysis. The two dominant organisms in the 1010N product, NS500-9 and MPN2, were thereby found to be most closely related to Nitrosomonas and Nitrobacter, respectively, in the existing database. Using the nucleic acid sequences of the cloned DNA, organism-specific DNA probes were designed for both NS500-9 and MPN2. Unfortunately, difficulties were encountered in using the probes to monitor 1010N activity levels via quantitative dot blot hybridizations (rRNA-DNA). Therefore, efforts were redirected to using the TGGE semi-quantitatively with an internal PCR standard (BrÃ¼ggeman, et al., 2000) to estimate original cell numbers of 1010N within a mixed consortium. This method was not applicable to our system due to substantial preferential binding of the primers to template other than the standard. Samples from a laboratory-scale bioreactor, bioaugmented with 1010N, were used in an attempt to correlate an increase in activity with a detectable shift in population via TGGE. No detectable shift in population was detected in these samples even though the system exhibited increased levels of nitrification. Therefore, the sensitivity of the TGGE system was also examined by determining the limits of detection when 1010N was present in activated sludge. In both whole cell spiking experiments and genomic DNA spiking experiments, it was found that 1010N must be present at a level of at least 5% of the total population in order to be detected. While this provides some information about microbial populations, in order to evaluate the biological activity of a system, nucleic acid probes should be used in a rRNA based study.

Abstract:

Det samhälle vi lever i idag ser inte ut som det gjorde när våra fäder och deras generation växte upp. Utvecklingen har gjort att både globaliseringen och speciellt tekniken som berör information och kommunikation har tagit ett stort steg framåt.Tack vare teknikutvecklingen får många personer tillgång till en ny typ av information. Idag känner flertalet konsumenter till att det förkommer flera olika mer eller mindre farliga kemikalier som finns kvar i de klädesplagg som hänger i butik. En marknad har uppstått med kläder som är miljö- och hälsovänligt tillverkade. En övergriplig och en djupgående konsumentundersökningen har genomförts, samt en konkurrentanalys. Utifrån undersökningarna har vi utformat en övergriplig affärsplan. Syftet med uppsatsen är att undersöka, beskriva och analysera hur ett företag går tillväga för att starta upp en verksamhet som säljer miljö- och hälsovänliga småbarnskläder för barn i åldern 0-3 år. Anledningen till att vi valt att inrikta oss på småbarn är att barnen i så små åldrar har känsligare hud och lättare får allergier. Därför är ekologiskt framställda kläder viktigare för småbarn än för vuxna. Vår undersökning har i första hand ett beskrivande syfte men även till viss del ett explorativt syfte. Det innebär att när vi påbörjade den här studien så hade vi en relativt liten kännedom om undersökningsproblemet. Vi har dels använt oss av en kvalitativ metod och dels en kvantitativ metod och anser att vi har använt oss av en tvärsnittsansats i samtliga undersökningar. I vår studie har vi valt att kombinera primär och sekundärdata. De primära källor som vi har använt oss av är exempelvis vår marknadsundersökning. Grunden för arbetet, det vill säga vår teori som skapat våra problemformuleringar är sekundärdata.I slutsatsen har vi kommit fram till att det finns konsumenter som efterfrågar småbarnskläder som är miljö- och hälsovänliga via internet. Vi anser även att det finns ett sätt att differentiera sig på marknaden med vårt valda koncept. Vi skulle t.ex. kunna erbjuda ett sortiment med könsneutrala kläder som ej förekommer i större mängder i dagsläget. Det förekommer inte heller så många företag som erbjuder särskilt generösa servicevillkor. The society we live in today does not look like it did when our ancestors and their generation grew up. The development has made the globalization and technology, especially concerning information and communication taken a big step forward. Thanks to technological advances, many people have access to a new kind of information. Today a majority of consumers knows that more or less hazardous chemicals might remain in the garments that are hanging in the store. A market has emerged with clothes that are free from substances that are unhealthy and bad for the nature. A overall consumer survey, a profound survey and a competitor analysis has been done. From the surveys we have developed a simple business plan. The purpose of this essay is to explore, describe and analyze how to start up a company with a concept of selling eco-friendly and healthy clothes for children aged 0-3 years. The reason to why we chose to focus on toddlers is that a child in young age has a more sensitive skin and is more susceptible to allergies. Organically produced cloths are for that reason more important for toddlers than for adults. Our study has primarily had a descriptive purpose but also partly an investigational purpose. This means that when we began this study, we had quite little knowledge of the investigation problem. We have partly used a qualitative method and partly a quantitative method and we have used a cross-sectional approach in all investigations. In our study, we have chosen to combine primary and secondary data. The primary sources we have used are for example our market researches. The basis for the work, our theory that created our problem formulations is secondary data. In the conclusion, we are taking up conclusions that there are consumers who are seeking for toddler clothes that are eco-friendly and healthy by web shops. We also believe that there is a way to differentiate against the competitors with our selected concept. We could, for example offer a range of unisex clothes that are not present in significant quantities in the present situation. There are currently not many companies that are offering these sorts of cloths.Program: Butikschefsutbildningen

Abstract:

Cette thèse Cifre s’intéresse au comportement sous impact de structures de protection issues de la technologie Bloc Armé® proposée conjointement par Géolithe Innov et Géolithe. La structure est composée de blocs en béton liaisonnés par des armatures métalliques verticales et horizontales. L’innovation principale réside dans le système d’armatures qui assure un liaisonnement des blocs et confère à la structure une capacité à répartir les efforts et à dissiper de l’énergie.Des essais à échelle réelle permettent de caractériser la réponse dynamique de la structure selon deux types d’essais. Premièrement, la structure mise en œuvre horizontalement sur une couche support est soumise à des impacts à haute énergie (2000 kJ) par lâchers verticaux d’un impactant. Deuxièmement, des essais à énergie moindre (125 kJ) sont réalisés par impact horizontaux sur un mur vertical de dimensions limitées. Des modèles réduits de la structure, à l’échelle ¼, sont également impactés, au laboratoire. Cette campagne est l’occasion de tester de nombreuses configurations de mur dans des conditions d’impact variées. Ces campagnes expérimentales permettent d’illustrer les mécanismes par lesquels une telle structure articulée se déforme sous sollicitation dynamique localisée. Les différents modes de déplacement des murs et certains phénomènes dissipant l’énergie d’impact sont mis en évidence et quantifiés. Les nombreuses mesures faites lors des essais constituent une importante base de données expérimentales, pour accompagner le développement du modèle numérique.Un modèle numérique aux différences finies est proposé pour cette structure. Une approche réaliste est suivie pour la modélisation : chacun des éléments de la structure est modélisé explicitement. Un modèle simple est volontairement considéré pour le béton constitutif des blocs. Le modèle est calibré d’après des valeurs issues de la littérature et des mesures faites spécifiquement. La confrontation des résultats de simulations d’impact avec les résultats expérimentaux témoigne d’une bonne aptitude du modèle à reproduire le comportement dynamique global de la structure et à estimer son déplacement résiduel, en particulier. Le modèle permet de quantifier la dissipation d’énergie découlant de la plastification du béton des blocs et des frottements dans la structure. Le modèle est ensuite utilisé pour simuler la réponse de murs de géométries variées et sous impact à haute énergie. Les perspectives de ce travail sont de proposer un modèle robuste capable de simuler des impacts à énergie de l’ordre de 5 000 kJ sur des ouvrages dont la géométrie pourra être complexe This Cifre thesis investigates the impact response of protective structures based on the Bloc Armé® technology, developed by Géolithe Innov and Géolithe. This structure is made of concrete blocks linked by vertical and horizontal metal reinforcements. The main innovation lies in the reinforcement system which ensures the bonding of the blocks and gives the structure an ability to distribute the forces and dissipate energy.Two types of real-scale experiments permit to characterize the dynamic response of the structure. Firstly, the structure laid horizontally on a support layer is subjected to high- energy impacts (2000 kJ) by freely dropping of a projectile. Secondly, lower energy impact tests (125 kJ) are carried out by horizontal impact on a vertical wall of limited dimensions. Reduced models of the structure, at ¼ scale, are also tested under impact in the laboratory. This campaign permits to test many walls of different configurations under various impact conditions. These experimental campaigns illustrate the deformation mechanisms under localized dynamic solicitation for this kind of articulated structure. The different displacement modes of vertical walls and several phenomena dissipating impact energy are highlighted and quantified. The numerous measurements made during the tests constitute an important experimental database, supporting the development of the numerical model.A numerical model, developed with the finite differences method, is proposed for this structure. A realistic approach is followed for the modeling: each element of the structure is modeled explicitly. A simple model is deliberately considered for the concrete constituting the blocks. The model is calibrated based on values from the literature and measurements made specifically. The comparison of impact simulations results with experimental ones attests of the ability of the model in reproducing the global dynamic behavior of the structure and in estimating its residual displacement, in particular. The model quantifies the energy dissipation resulting from plasticization of the concrete blocks and from friction in the structure.The model is then used to simulate the response of walls of various geometries and under high energy impact. The outlooks of this work are to propose a robust model able to simulate the structure response to impacts with energies up to 5,000 kJ, considering structures with complex geometries

Abstract:

This thesis explores cultural differences on interactive design features used in websites of South Korea and the United Kingdom from the perspective of both: professional website designers and end-users. It also investigates how the use of interactive design features from different cultures change over time. Four interaction types on websites; User to Interface (U2I), User to Content (U2C), User to Provider (U2P), and User to User (U2U) interactivity, and three interaction types on blogs; Blogger to Interface (B2I), Blogger to Content (B2C) and Blogger to Blogger (B2B) interactivity have been identified. Four cultural dimensions were used for the theoretical base of this study based on which four hypotheses were proposed in relation to the interaction types identified above; (a) High versus Low Context cultures for U2I, (b) High versus Low Uncertainty Avoidance for U2C, (c) High versus Low Power Distance for U2P and (d) Individualism versus Collectivism for U2U interactivity, in order to discover the effects of national cultures on interactivity in websites. We derived our own interactivity dimensions and mapped them to the four interaction types for websites and three for blogs. Interactive design features were derived from interactivity dimensions and examined in our studies. The findings revealed that there have been some changes towards homogeneity in the use of interactive design features on charity websites between South Korea and United Kingdom although there is still evidence of some cultural differences. With regard to end-users’ perspective, the result show that the use of interactive design features of blogs may be influenced by culture but this is only within a certain context. The findings also provide a valuable indication that users interacting within the same blog service can be considered as being shared concerns rather than shared national location, thus create a particular type of community in which bloggers are affected by social influence so they adopt a shared set of value, preferences and style that would indicate almost a common social culture. As a result, the cultural differences derived from their country of origin do not have that much impact.

Abstract:

Dans les dernières décennies, l'augmentation de la consommation des services de soins et la croissance de la population ont fait de l'élimination du gaspillage et l'amélioration continue de la productivité de plus en plus cruciale pour les hôpitaux. La productivité et l'efficacité d'un hôpital dépendent des conditions de travail des soignants qui sont influencés fortement par l'organisation des lieux de travail et des installations [Dares (2013)]. L’agencement des installations consiste à "déterminer l'organisation physique d'un système de production et de trouver l’arrangement le plus efficace de ‘n’ installations dans ‘n’ positions" [Singh et Sharma (2006)]. L’agencement des installations a un grand impact sur la productivité et l'efficacité du fonctionnement d'un hôpital. Etant conscient de ce besoin, le travail que nous présentons vise à trouver une solution à l’agencement des salles du Bloc Opératoire "le coeur de l'hôpital", ainsi que les salles annexes en proposant un outil intelligent que nous mettons à la disposition des maitres d’ouvrages pour optimiser leur conception du bloc opératoire. Les méthodes que nous avons explorées pour la réalisation de ce travail sont les méthodes exactes, les heuristiques, les métaheuristiques et les méthodes intelligentes, ce qui nous a permis de comparer les différentes approches afin de fournir la meilleure solution pour différents scénarios de problèmes. Nous présentons les contributions majeures de notre travail, à commencer par l'application de la programmation mathématique en nombres entiers mixtes (Mixed Integer Programming (MIP)) pour résoudre le problème d’agencement du bloc opératoire (Operating Theater Layout Problem (OTLP)) comme la première contribution scientifique. Ce travail considère trois structures différentes (multi-section, multi-étage et multi-rangé) dans deux types d'environnement différents, tout en optimisant deux fonctions objectifs différents. La combinaison de ces différentes composantes donne lieu à neuf modèles MIP pour résoudre l’OTLP pour lesquels une solution optimale a été atteinte pour des problèmes avec jusqu'à quarante salles. L'utilisation de Systèmes Multi-Agents (MAS) pour résoudre le problème d’agencement des installations est la deuxième contribution scientifique que nous présentons dans le cinquième chapitre. Dans la littérature, on retrouve un seul travail [Tarkesh et al., (2009)] ayant appliqué le MAS pour résoudre des problèmes de petites tailles, ce qui rend notre travail, le premier adoptant MAS pour répondre à la fois le FLP sous environnement statique et dynamique pour des problèmes de grande taille en utilisant un algorithme en trois étapes pour résoudre OTLP. La plate-forme multi-agents développée exploite les trois différents protocoles de communication d’agents, à savoir la coordination, la coopération et la négociation pour concevoir différentes architectures d’agents afin de faire face à l’OTLP statique et dynamique. La dernière contribution consistant en l'utilisation de l’optimisation par essaim de particules (Particle Swarm Optimization (PSO)) sous une représentation continue de l’espace de recherche pour résoudre le problème d’agencement multi-rangée est présentée dans le sixième chapitre. Puisque la PSO est généralement utilisé pour résoudre les problèmes d’affectation ou les FLP avec une représentation discrète, la formulation actuelle est parmi les rares travaux traitant la représentation continue du FLP. Nous avons conçu une nouvelle technique de codage des particules et des heuristiques appropriées pour générer des solutions initiales et pour effectuer la procédure de recherche locale. Une autre nouveauté est liée à l'application de la PSO à un problème de structure multi-rangé, qui n'a pas été abordé auparavant car à notre connaissance, les travaux avec la PSO ont formulé le FLP comme une structure d’une seule rangée ou dans le meilleur des scénarios, comme une structure à deux rangées In the last decades, the important increasing consumption of health care and the growing of population make elimination of waste and continuous productivity improvement more and more critical for hospitals to provide their care services effectively and efficiently. The productivity and efficiency of a hospital depends on the caregivers working conditions, which are impacted greatly by the work place and the facilities organization [Dares (2013)]. Facilities planning “determines the physical organization of a production system and finding the most efficient arrangement of ‘n’ indivisible facilities in ‘n’ locations” [Singh & Sharma (2006)]. Thus, facilities planning has a great impact on the productivity and efficiency of running a hospital. Being aware of this need, the work we present aims to find a solution to facilities planning for the Operating Theater “the heart of hospital” by proposing an intelligent tool we make available to decision makers for optimizing their operating theater design. Our research work focuses on the use of operational research methods in order to find a solution for this optimization problem. Methods we explored for the realization of this work were variant, namely exact algorithm, heuristics, metaheuristics and intelligent methods, which allow us to compare different issues in order to provide the best solution to different scenarios of problems. Thus, in this dissertation we present the major contribution of our work, starting with the application of Mixed Integer Programming (MIP) to solve Operating Theater Layout Problem (OTLP) as the first scientific contribution. This work considers three different formulations (i.e. the multi-sections, the multi-floors and the multi-rows) in two different environment types (i.e. static and dynamic) while optimizing two different objective functions (i.e. to minimize the total traveling cost and to maximize the total adjacency rate). The combination of these different components gives rise to nine MIP models to solve the OTLP for which optimal solution was provided to problems with until forty facilities. These contributions are presented in the third and fourth chapters. The use of Multi-Agent System (MAS) to solve Facility Layout Problem (FLP) is the second scientific contribution we present in chapter five. In literature, only one work [Tarkesh et al., (2009)] applied the MAS to solve small sized problems, which makes our work the first one adopting MAS to address both the static and dynamic FLP for large sized problems using a novel algorithm running in three steps to solve OTLP. The developed multi-agent platform exploit the three different agents’ protocols of communication, namely coordination, cooperation and negotiation to conceive different agents’ architectures to deal with the static and dynamic OTLP. The last contribution consisting on the use of Particle Swarm Optimization (PSO) under continuous layout representation to solve multi-rows FLP is presented in chapter six. Since the PSO is generally used to solve assignment problems or discrete FLP, the actual formulation is among the few works dealing with the continuous one. This leads us to conceive a novel encoding technique and the appropriate heuristics to generate initial solutions and to perform the local search procedure. Another novelty is related to the application of PSO to a multi-rows layout problem, which was not addressed before. To the best of our knowledge, PSO works usually formulate the FLP as a single row or in the best of scenarios, as a double-rows problem

Abstract:

Pour prévoir et mettre au point la mise en forme d'objets en verre à partir de feuilles plates, les simulations numériques par éléments finis sont développées pour deux grands procédés, le Press-bend et le Blow-bend. Ces deux procédés, utilisés actuellement par les fabricants verriers, comportent deux phases essentielles: le pressage et le fluage pour le premier, le soufflage et le fluage pour le second. Ces modes de production nécessitent la maitrise d'un nombre important de paramètres. Les délais de conception et la minimisation des couts de revient limitent le nombre de mises au point expérimentales. C'est à ce niveau que les simulations numériques en tant qu'outil d'étude de faisabilité et d'optimisation, joue un rôle déterminant. Celles-ci sont associées à une stratégie originale intégrant la conception assistée par ordinateur pour décrire les entités géométriques et surfaciques, et à la métrologie afin de vérifier les critères dimensionnelles. A partir des prescriptions initiales du concepteur, la confrontation des résultats numériques et des relevés expérimentaux pour quatre volumes formes par Press-bend et Blow-bend permettent la validation des paramètres process utilisés. Finalement, une méthode inverse est mise en œuvre afin d'optimiser, dans un premier temps, la carte de températures dans le volume avant formage puis, la topologie des outils de mise en forme.

Abstract:

Étant une collaboration entre l’ULB et l’ENSAV La Cambre, ce doctorat en art et sciences de l’art comporte une recherche théorique et une artistique. Les relations entre les deux pôles sont des relations d’ordre critique. Il existe certes des collisions où le travail théorique est un commentaire critique sur le travail artistique, et si possible, vice versa. Il ne s’agit pas d’un commentaire littéral sur mes œuvres, mais d’un commentaire qui reflète mes propres incertitudes quant à ma position d’artiste au sein et à l’égard de l’art contemporain.Le changement de pouvoir en 1989 mit les artistes d’Europe de l’Est devant des choix :changer et accepter le langage dominant de l’art contemporain développé à l’Ouest pendant les dernières 40 années, s’appropriant ainsi « l’histoire de l’art manquée » ;utiliser la symbolique totalitaire comme un langage qui les rend reconnaissables précisément par leur altérité ou bien développer d’autres types de réactions personnelles. Afin de mieux comprendre la situation de départ de ces artistes, le premier chapitre est consacré à l’organisation du marché de l’art dans l’ancien bloc de l’Est. Le deuxième chapitre traite des représentations incarnées le plus souvent par les artistes d’Europe de l’Est et des stéréotypes qui ont influencé la perception du monde occidental à l’égard de leur identité. En ressortent quelques images stéréotypales principales, nées au cours d’époques différentes :celle de la barbarité comme vision de soi (qui date du 18ème siècle), celle des révolutionnaires avant-gardistes (des années 1920), celle de la quête pour la liberté artistique occidentale et celle de la victimisation (au cours de la guerre froide).Les trois cas de réactions individuelles étudiés sont ceux de Komar et Melamid, Zofia Kulik et Gerhard Richter. Les artistes conceptuels russes Komar et Mélamid développent un travail où ils emploient des styles artistiques différents choisis pour leur qualité théâtrale :en tant que masques qui permettent une critique idéologique et en se servant souvent de la fiction. Leur œuvre se sert de la relativisation des notions d’identité personnelle et artistique ainsi que du style. Zofia Kulik, artiste polonaise, utilise dans son œuvre des sujets en tant qu’objets, au point que sujets et objets deviennent interchangeables. D’une manière paradoxale, cette subordination est une source de libération, notamment lorsque Kulik s’en sert pour effectuer un détournement ironique contre toute domination idéologique, d’abord envers le régime totalitaire polonais et ensuite envers la culture de l’art contemporain occidental. La réaction de Gerhard Richter s’exprime dans le contrôle que l’artiste exerce sur la représentation de son passé. D’une manière assez particulière, Richter internalise la dialectique du dehors et du dedans typique de la guerre froide :toute une partie de son œuvre datant d’avant son émigration d’Allemagne de l’Est et de la période transitoire qui s’ensuit, reste dans le dehors, une partie de son œuvre n’est pas reconnue comme légitime. La partie artistique de la thèse vise une recherche de position personnelle et artistique par rapport au problème. Elle comporte des œuvres différentes faites au cours du doctorat et visibles dans son deuxième volume. Doctorat en Art et Sciences de l'Art info:eu-repo/semantics/nonPublished

Abstract:

Dans les communications sans fil sur des canaux à évanouissement, en particulier à antennes multiples, la connaissance instantanée des coefficients de canal, appelés informations d’état de canal (CSI), est essentielle car elle permet d’adapter la transmission et la réception aux conditions actuelles du canal. La communication avec CSI a priori au niveau du récepteur est dite cohérente. En pratique, cependant, le CSI n’est pas disponible avant la communication et doit être estimé à un coût qui ne doit pas être ignoré, en particulier dans un environnement hautement mobile. Ainsi, la communication sans CSI a priori, également appelée communication noncohérente, est un cadre plus pratique et général. Cette thèse contribue à la compréhension des limites théoriques des communications noncohérentes, ainsi qu’à la conception d’un système de communication pratique noncohérent à évanouissement par bloc. Nous considérons trois scénarios: le canal point à point (P2P), le canal à accès multiple (MAC) et le canal de diffusion (BC).Dans la première partie, nous étudions les limites fondamentales des communications noncohérentes en termes de débit de données et de degrés de liberté (DoF) réalisables. Nous considérons un évanouissement par bloc générique dans lequel le canal a une entropie différentielle finie et un second moment fini. Nous établissons d’abord le DoF optimal pour le canal P2P noncohérent à entrées multiples et sorties multiples (MIMO) en utilisant l’approche de la dualité pour borner les informations mutuelles. Deuxièmement, en utilisant une approche de dualité similaire, nous dérivons la région de DoF optimale pour le MAC SIMO à deux utilisateurs, qui peut être obtenue par partage de temps entre des schémas à pilotes simples. Troisième, nous dérivons les régions débit et DoF réalisable pour le BC MIMO noncohérent avec un évanouissement spatialement corrélé en exploitant la diversité de corrélation de transmission, qui est la différence entre la corrélation subie par différents utilisateurs. Ce faisant, nous concevons soigneusement des schémas de transmission basés sur des pilotes et sur le partage de débit, la superposition de produits et une combinaison de ceux-ci pour transmettre efficacement des signaux dans les parties communes et mutuellement exclusives des sous-espaces de corrélation. Dans la deuxième partie, nous concevons la constellation et les schémas de détection efficaces pour les communications noncohérentes sur le canal d’évanouissement de type Rayleigh par bloc. Premièrement, nous proposons une constellation Grassmannienne structurée pour le canal P2P SIMO qui est simple à générer, a une efficacité d’empilement élevée, admet un étiquetage binaire simple mais efficace et permet une détection efficace douce et dure. Deuxièmement, nous étudions la conception de constellation conjointe pour le MAC MIMO. Nous introduisons des critères de conception simples et efficaces afin de minimiser l’erreur de détection conjointe et proposons quelques constructions de constellation simples. Troisièmement, nous proposons un schéma de détection souple multi-utilisateurs noncohérent pour le MAC SIMO à l’évanouissement de Rayleigh corrélé spatialement basé sur l’inférence approximative par propagation d’espérance. Ce schéma présente une complexité polynomiale dans la dimension du canal tout en produisant des marginaux postérieurs approximatifs par utilisateur précis conduisant à des performances d’erreur quasi-optimales In wireless communication over fading channels, especially multiple-antenna communication, the instantaneous knowledge of channel coefficients, so-called channel state information (CSI), is critical because it enables to adapt the transmission and reception to current channel conditions. The communication with a priori CSI at the receiver is said to be coherent. In practice, however, CSI is not granted for free prior to communication and needs to be estimated at a cost that should not be ignored, especially in a highly mobile environment. Thus, communication without a priori CSI, also known as noncoherent communication, is a more practical and general framework. This thesis contributes to the understanding of the theoretical limits of noncoherent communications, as well as the design of a practical noncoherent communication system in block fading. We consider three scenarios: the point-topoint (P2P) channel, the multiple-access channel (MAC), and the broadcast channel (BC).In the first part, we study the fundamental limits of noncoherent communications in terms of achievable data rate and degrees of freedom (DoF). We consider generic block fading in which the channel has finite differential entropy and finite second moment. First, we derive the optimal DoF for the noncoherent multiple-input multiple-output (MIMO) P2P channel by using the duality approach to bound the input-output mutual information. Second, using a similar duality approach, we derive the optimal DoF region for the two-user noncoherent single-input multiple-output (SIMO) MAC, which can be achieved by time sharing between simple pilot-based schemes. Third, we derive achievable rate and DoF regions for the noncoherent MIMO BC with spatially correlated fading by exploiting the transmit correlation diversity, which is the difference between the correlation experienced by different users. In doing so, we carefully design pilot-based transmission schemes based on rate splitting, product superposition, and a combination of them to effectively transmit signals in both the common and mutually exclusive parts of the correlation subspaces. In the second part, we design the constellation and efficient detection schemes for noncoherent communications over Rayleigh block fading channel. First, we propose a structured Grassmannian constellation for the SIMO P2P channel that is simple to generate, has high packing efficiency, admits a simple yet effective binary labeling, and allows for efficient soft and hard detection. Second, we investigate joint constellation design for the MIMO MAC. We introduce some simple and effective design criteria so as to minimize the joint detection error, and propose some simple constellation constructions. Third, we propose a noncoherent multi-user soft detection scheme for the SIMO MAC in spatially correlated Rayleigh fading based on expectation propagation approximate inference. This scheme has polynomial complexity in the channel dimension while producing accurate approximate per-user posterior marginals leading to near-optimal error performance

Abstract:

For whom do we draw buildings? Why does contemporary architecture look the way it does?Why are certain aesthetics considered more valid than others? With this project, I propose Dirty Geometry: norm-bending design that could challenge conventions within the field of architecture. It is an investigation of concepts such as ugliness, beauty, architecture and the human body, interiority, femininity and ”bad taste”. The purpose is to, with the aid of parametric design processes, make Stockholm less boring and more dirty. Dirty Geometry is both the creative process sprung from one’s personal desires, and the resulting design. It aims to celebrate the weird, playful and colorful in an empowering way. This thesis project draws a lot of inspiration from camp aesthetics and drag culture, because of the way humour is used in a subversive way to question gender identities, power structures and norms.

Abstract:

The Internet is a ubiquitous feature in everyday life, but its application to social movements has yet to be completely understood. This phenomenological study examines the lived experiences of bloggers who focused on the gay, lesbian, bisexual, and transgender (LGBT) movement in the United States to understand the impact bloggers and their work as online activists have on existing LGBT social movement organization and operation. Data collection is gathered from semi-structured and open-ended interviews with four social movement bloggers using web-conference software over the course of three months. The results of this study indicated that internet has empowered individual activists, allowing them to gather a following and share their views to a large audience over the web, independent from existing social movement organizations. Consequently, bloggers and online activists maintain a relationship with existing social movement structure that is both collaborative and antagonistic. The results of this study contribute to the current understanding of social movement organizations as well as the impact of technological innovations on social movement advocacy.

Abstract:

“Overworking to death” is a phenomenon that has been noticeable in developing countries. The cause of death is mainly through ischemic strokes. While the victims’ occupations differed, they all shared a common characteristic, being positioned in a sedentary work, ranging from IT workers to doctors. This project’s aim was to develop a product that prevented or decreased the strokes that derived from sedentary overwork. This was mainly tackled by preventing one of the three causes of developing blood props, slowed blood flow. In order to gather rich data of the phenomenon, a qualitative study was conducted in China, during two months. By doing an extensive structured sampling, information rich data could be gathered during a short period of time. Data were derived from observations, questionnaires and an interview, which then was interpreted to customer needs and the final product specification. The final product became a trouser with an in built dynamic compression mechanic, that can compress the veins mostly during sitting activities, in order to prevent blood stasis. The compression mechanic works like the Chinese finger trap; compressing the calves while sitting and stretching the legs forward. It is made only out of polysaccharides fibres; cotton and corn. "Guolaosi" eller död från överarbete är ett fenomen som i regel uppkommer bland utvecklingsländer. Dödsorsaken är huvudsakligen genom stroke. Offrens yrken varierar allt från professorer, IT-arbetare till läkare. De delar dock en sak gemensamt; att arbeta under långa perioder stillasittande. Projektets mål var att utveckla en produkt som minskar dödliga följderna av sedentära överarbete, genom att förebygga en av de tre orsakerna för att utveckla blodproppar; saktad blodström. Målgruppen var då kineser av de yrken som hade tidigare drabbats av fenomenet. För att samla informationsrika data om fenomenet genomfördes en kvalitativ studie i Kina under två månader. Genom att göra en omfattande strukturerad provtagning kunde informationsrika data samlas under en kort tidsperiod. Fältstudien bestod av observationer, frågeformulär och en intervju, som då tolkades till kundbehov och eventuellt produktspecifikationen. Den slutliga produkten kom att bli ett par byxor med en inbyggd dynamisk komprimeringsmekanism, som kan komprimera venerna under sittande aktiviteter, för att förhindra saktad blodström. Kompressionsmekanismen fungerar som den kinesiska fingerfällan. Den komprimerar blodkärlen medan personen sitter och sträcker benen framåt. Produkten är konstruerad på så sätt att den kan tillverkas endast av polysackariders tråd, från bomull och majs. Vilket är lämpligt för Kinas lokala resurser.
