The effective and efficient implementation of a project requires a composition of knowledge, skills, techniques and tools that are used and defined in many project management guides. This composition is what we call as project management. This study about the degree of use of the practices consisted in a quantitative field survey with the individuals working with project management in their companies. Thus we identified the characteristics of professional, of your organization, the use of practices, and metrics of success of the project. It is emphasized that this research study is limited to Brazilian audience. To achieve the study goals, is was developed as: descriptive analysis, where we seek to describe the reality of project management presented by professionals; explanatory, aiming at clarifying the degree of utilization of these practices in relation to the PMBOK Guide in organizations; and exploratory, as there was little knowledge accumulated and systematized in this area in Brazil . We also use the literature review to consolidate the study of theories relating to the area of project management based on guides , periodicals and journals , academic papers and books on the subject matter. Through the quantitative analysis we sought the compliance of the data collected to allow the logical analysis of information in the process of searching for answers about the evaluation of the PMBOK Guide’s project management principles use degree by project professional in the Brazilian market. The results showed different use degrees of practices according to the nine knowledge areas of the PMBOK Guide and intriguing revelations when analyzed under perspectives like an existence of a PMO (project management office) in the company, project success and among others revealing that the context where the professionals and their organizations can contribute for a significant changing in the use degrees analyzed. This study aims to serve as factor for prospecting of others studies in the area of project management, promoting Brazilian scientific publications. / Esta dissertação de mestrado tem por objetivo relatar o resultado de um estudo de verificação das práticas de gerenciamento de projetos, baseadas no Guia PMBOK (Project Management Body of Knowledge), presentes no dia-a-dia pelos profissionais de projetos das organizações brasileiras. A execução eficaz, eficiente e efetiva de um projeto necessita de uma composição entre conhecimentos, habilidades, técnicas e ferramentas definidos em diversos guias de gestão de projetos. Essa composição é o que se denomina: gerenciamento de projetos. A fundamentação prática aqui apresentada baseou-se em uma pesquisa de campo quantitativa, que inquiriu sujeitos organizacionais atuantes em gestão de projetos em suas empresas. Assim, pôde-se verificar as características do profissional, de sua organização, do uso das práticas e das métricas de sucesso do projeto. Ressalte-se que este estudo limita-se ao Brasil, como ambiente em que atua o público-alvo de pesquisa. Para tanto, o estudo foi desenvolvido: de forma descritiva, a partir da realidade de gestão de projetos apresentada pelos profissionais; explicativa, tendo como objetivo central esclarecer qual o seu grau de utilização em relação ao Guia PMBOK, no contexto das organizações brasileiras; e exploratória, dado que existia pouco conhecimento acumulado e sistematizado a respeito deste tema, na área Brasil. A revisão bibliográfica, para consolidar o estudo das teorias referentes à área gestão de projetos, deu-se por meio de guias, periódicos e jornais especializados, trabalhos acadêmicos e livros sobre o tema em questão e demais textos virtuais. Da análise quantitativa, buscou-se a conformidade sobre os dados coletados a fim de se consolidar a consistência lógica das informações obtidas nas respostas sobre a avaliação do grau de uso do preceitos de gerenciamento de projetos do Guia PMBOK por parte dos profissionais de projetos, do mercado brasileiro. Os resultados demonstraram diferentes graus de uso das práticas relativas às nove áreas de conhecimento do Guia PMBOK. Pôde-se apurar, também, revelações intrigantes como a existência de um EGP (escritório de gestão de projetos) na empresa, como no contexto, no qual estão inseridos os profissionais e suas organizações, podem contribuir de modo significativo tanto na alteração dos graus de uso como no sucesso do projeto. Almeja-se que o presente estudo possa servir de elemento prospectivo para outras pesquisas na área de gerenciamento de projetos, fomentando a realização de trabalhos e publicações científicas, de âmbito brasileiro.

Afin de réduire les bruits rayonnés en sortie de guide d’onde, des traitements acoustiques localement réactifs, comme les structures « Plaque perforée/Nid d’abeilles », peuvent être appliqués en liner. La conception de ces liners devient alors un challenge important avec l’apparition de nouvelles normes sur le bruit et impose de posséder une très bonne connaissance du comportement de ces traitements, en particulier leur impédance de surface. Néanmoins, la caractérisation de cette impédance n’est pas une chose facile et est généralement réalisée via des modèles semi-empiriques comme ceux de Guess, Elnady, Allam ou expérimentalement par des méthodes de mesures directes ou inverses. Ces approches inverses permettent, par la confrontation d’une modélisation du problème avec des observations expérimentales, de retourner, au travers d’une fonction coût, l’impédance du traitement. Ces méthodes ont l’avantage de réaliser une observation dans les conditions réelles d’utilisation du traitement. En effet, de nombreux paramètres influencent l’impédance de surface comme la présence d’un écoulement, l’incidence de l’onde… Dans cette thèse, une méthode d’identification de l’impédance est proposée. A partir de l’impédance de surface d’un traitement « Plaque perforée/Nid d’abeille » prédite par un modèle empirique via ses paramètres géométriques (épaisseur de la plaque, diamètre des perforations…), une méthode basée sur l’approche Bayésienne est implémentée afin de remonter à l’impédance réelle du traitement. Le problème étudié consiste en la propagation d’une onde dans un tronçon rectangulaire traité sur sa face supérieure et la mesure des pressions acoustiques est réalisée sur le banc d’essai de l’Université Technologique de Compiègne avec un écoulement rasant. Un modèle de propagation d’ondes dans le conduit est développé via la technique du raccordement modal, afin de prédire la pression aux positions des microphones pour n’importe quelle valeur d’impédance. A partir de la mesure et de la simulation, la règle de Bayes peut être appliquée afin de construire la densité de probabilité a posteriori. Cette densité de probabilité est alors échantillonnée au travers d’un algorithme Évolutionnaire de Monte Carlo par Chaîne de Markov (EMCMC). L’intérêt principale de cette méthode, est d’obtenir de nombreuses d’informations statistiques sur les paramètres caractérisant l’impédance de surface comme leur distribution et leur corrélation. / Locally reactive acoustic liners such as honeycomb structures with perforated panels can be modeled with a surface impedance in standard numerical models. However, the characterization of this impedance is not always straightforward. Empirical models or standing wave tube measurements are generally used to get the behavior of these acoustic treatments. Unfortunately, these methods provide only an evaluation of the impedance under specific conditions. Moreover, the conditions of use can change significantly the acoustic liners behavior as grazing flow conditions or oblique incident waves. A characterization of locally reactive acoustic liners is presented here. Starting from a set of parameters and represents a surface impedance using empirical model, an inverse method based on Bayesian approach is used to return the surface impedance taking in consideration the real conditions of use. A rectangular duct treated by a liner on its upper face is considered and these conditions are similar to the experiment present at the Université de Technologie de Compiègne. This inverse method requires a direct model to predict the pressure at some microphone positions with any surface impedance. The model used in the following is based on the Mode-Matching method. From the direct analytical model, the Bayes'rule is then used to get the posterior probability density function of the estimated impedance. An Evolutionary Monte Carlo by Markov chain (EMCMC) method is used to sample this posterior probability density. This method provides not only the best set of parameters but also some statistical information for each parameter.

Studien syftar till att se vilken betydelse projektet haft för flyktingguiderna samt att utifrån deras perspektiv få förslag på hur man kan förbättra projektet för en ökad integration. Resultatet som framkommer i denna studie visar på att flyktingguiderna känner en tillfredsställelse av att kunna hjälpa flyktingar, att de finner att projektet Flyktingguide bidrar till integration i längden, samt att projektet har utvecklingspotential. Genom intervjuerna målades det upp en bild av många lyckade möten över kulturgränserna där respondenterna uttryckt allt ifrån att de fått nya sociala nätverk i form av vänner, så väl som känslan av att ha fått en helt ny familjemedlem. / In this qualitative study, six refugee guides are interviewed as participants of the Refugee Guide project in the municipality of Falun. The study aims at seeing the importance of the project for the refugee guides and, from their perspective, suggesting ways to improve the project for increased integration. The results found in this study show that the refugee guides feel a sense of satisfaction, that they find that the Refugee Guide project contributes to long-term integration and that the project has development potential. Through the interviews, there was a picture of many successful meetings across the cultural borders where respondents expressed everything from gaining new social networks in the form of friends as well as the feeling of getting a whole new family member.

Les travaux de cette thèse s’inscrivent dans un projet de développement d’un Lab-On-Chip destiné à la biodétection. Les plateformes conçues sont basées sur des circuits optiques intégrés sur niobate de lithium. La particularité de ces circuits est qu’ils intègrent le phénomène d’interférence à la fonction de guidage des ondes lumineuses.La fonction d’interférométrie est assurée grâce à une cavité Fabry-Pérot intégrée à un guide d’onde rectiligne et à une structure Mach-Zehnder. Lorsque la surface des supports de ces circuits est bio-fonctionnalisée, ces microsystèmes deviennent sensibles à des molécules cibles. Cette sensibilité se traduit par une variation de l’indice effectifde l’onde en propagation par couplage évanescent modifiant ainsi les conditions de résonance du résonateur Fabry-Pérot. Le vrai challenge de ce travail réside essentiellement dans la bio-fonctionnalisation du niobate de lithium.A notre connaissance, ce matériau favori en optique guidée grâce à ses propriétés physiques exceptionnelles n’a été que rarement sujet à des modifications chimiques de surface. L’implantation réussie de groupements fonctionnels amines à la surface de ce matériau a permis de générer un lien covalent entre ce support et les groupements fonctionnels des molécules sondes. En raison de la grande affinité entre l’avidine et la biotine, ce couple a servi de modèle pour la mise au point de ces bio-capteurs. Un suivi en temps réel des interactions à la surface était rendu possible par une expérimentation sur l’un des bio-capteurs. / The work of this thesis is part of a project of a Lab-On-Chip development intended for biosensing. The de-signed platforms are based on integrated optical circuits on lithium niobate. The peculiarity of these circuits isthat they incorporate the phenomenon of interference with the function of guiding light waves. The interferometricfunction is provided by a Fabry-Perot cavity embedded in a straight waveguide and a Mach-Zehnder structure.When the surface of these circuits substrates is biofunctionalized, these microsystems become sensitive to targetmolecules. This sensitivity results in a variation of the effective index of the propagation wave by evanescent cou-pling and modifying the resonance conditions of the Fabry-Perot resonator. The real challenge of this work liesin the biofunctionalization of lithium niobate. To our knowledge, this guided optics favorite material thanks toits exceptional physical properties has been hitherto rarely subject to chemical surface modifications. Successfulimplementation of amino functions on the surface of this material has generating a covalent bond between thissubstrate and the functional groups of the probe molecules. Due to the high affinity between avidin and biotin, thiscouple served as a model for the development of biosensors. A real-time monitoring of surface interactions wasmade possible by experimentation on one of biosensors.

All levels of society, individuals, businesses and governments, must be involved in order to reverse the unsustainable path that society is currently on. Though much has been written about what needs to be done, there is much less literature on how to do it. This study attempts to start filling this gap. This paper is focused on the Vision 2050 report which acknowledges the role businesses have in moving society towards sustainability. The Vision 2050 report which was released by the World Business Council for Sustainable Development explores the current reality business is facing and the opportunities that are available for them to incorporate sustainability into the mainstream of their business. The study examines how businesses can begin to integrate sustainability into their company’s operations and services, using the report for inspiration and the Framework for Strategic Sustainable Development as guidance. A suggested approach is presented in the form of an implementation guide, which can be used by business to help them navigate their organization, collaborate with others and to develop an action plan as they work to integrating sustainability into their operations

Det är idag vanligt att konfektionsföretagen inte gör sina egna mönster till produktion. Istället skapar de tydliga produktionsspecifikationer och måttlistor som skickas till leverantör för att påbörja en produktutveckling och produktion. I brist på tid finns det en risk att specifikationerna är ofullständiga och detta kan i sin tur bidra till missförstånd eller egna tolkningar, detta gäller främst momentet då plagg mäts av. På grund av detta kan produktutvecklingen och produktionen påverkas på ett negativt sätt, processen kan dras ut och onödiga prototyper tillverkas. Idag finns det inte några direkta riktlinjer på hur plagg mäts av, därför skapas det i denna studie en mätguide för att se huruvida hjälpsamt eller inte det är och om det går att effektivisera produktutvecklingen och produktionen med hjälp av en sådan. Denna guide har använts vid avmätning av ett par jeans som flertalet testpersoner mätt av. Alla de tagna måtten har sammanställts och jämförts mot varandra men även mot det aktuella företagets toleranser, detta för att kunna utvärdera om guiden kan effektivisera produktutvecklingen och produktionen. Studien resulterade i differenser i de olika måtten, flera utanför företagets godkända toleranser, och visade på att det är ytterst viktigt att måttbeskrivningarna är tydliga likaså de komplimenterande skisserna. / Today it’s common for clothing companies to not make their own patterns for production. Instead they’re making detailed production specifications and measurement charts, which they send to the suppliers to start a product development process and production. Due to lack of time there’s a risk that the specifications are insufficient and this can result in misunderstandings and own interpretations, especially when it comes to measuring garments. The product development and the production can be affected negatively because of this, unnecessary prototypes are being made and the process is being protracted. There are, today, no guidelines on how to measure garments, therefore a measuring guide will be developed in this study and it’ll be tested to see if and how it can be helpful to make the production process more effective. The guide has been used to measure a pair of jeans and test persons have been measuring the same pair of jeans. The measurement values have been compiled and compared to each other but also to the current company’s acceptable tolerance values, this to evaluate if the guide can improve the product development and production efficiency. The study resulted in many differences in the measurements, several of them out of the company’s acceptable tolerance. This showed that it’s very important that the measurement descriptions and their sketches are clear and understandable.

La dermatite atopique, mieux connue sous le nom d’eczéma, est une condition chronique fréquente dont la prise en charge est souvent complexe et difficile à comprendre. Cette étude prospective vise la conception et la validation d'un guide pratique écrit ainsi qu'un questionnaire de connaissances en eczéma dans le but de combler un besoin concernant la disponibilité d'un programme d'éducation thérapeutique accessible à la population souffrant de cette maladie. Les objectifs secondaires sont d'évaluer l'impact de ces outils sur les connaissances en eczéma à court terme ainsi que l'impact du niveau de littératie en santé et des variables sociodémographiques sur ces mêmes connaissances. Un projet pilote a d’abord été conduit auprès d’onze futurs parents d'un cours prénatal de l'Université de Sherbrooke, suivi d'une phase expérimentale auprès de 107 patients âgés entre 18 et 45 ans de la clinique de dermatologie du Centre Hospitalier Universitaire de Sherbrooke (CIUSSS de l’Estrie-CHUS). Les analyses de validité et de fiabilité performées lors du projet pilote ont permis de faire les modifications nécessaires sur le guide pratique écrit ainsi que sur le questionnaire de connaissances afin de les rendre applicables à plus grande échelle. Ces outils modifiés ont par la suite été utilisés dans les études comparatives menées dans la phase expérimentale. Ces dernières ont démontré une amélioration statistiquement significative de la connaissance en eczéma à court terme par une comparaison des scores moyens au questionnaire de connaissances en pré-test et en post-test. Dans l’ensemble, aucune différence de progression de connaissance (delta entre le pré-test et le post-test) entre les différents sous-groupes de chaque variable sociodémographique n’a été démontrée de façon statistiquement significative. De plus, la courbe de progression de connaissances en pré-test et post-test est comparable entre les différents niveaux de littératie en santé. Ces derniers résultats démontrent l’absence d’impact des variables sociodémographiques étudiées ainsi que du niveau de littératie sur les outils à l’étude, ce qui supporte leur applicabilité à grande échelle. Mots clés: dermatite atopique, eczéma, éducation thérapeutique, guide pratique écrit, éducation en santé. / Atopic dermatitis, also known as eczema, is a common chronic disease for which treatments are often complex and difficult to understand. This prospective study aims to develop and validate a written action plan and a knowledge questionnaire about eczema in order to fill an existing gap in literature concerning the availability of a self-management training program that would be accessible to patients suffering from this condition. The secondary end-points aim to evaluate the impact of the written action plan as well as the impact of health literacy and other demographic variables on eczema knowledge over a short period of time. A pilot over 11 subjects was firstly conducted in a prenatal class at the University of Sherbrooke. Validity and reliability analyses were performed and allowed for alterations on the written action plan as well as the knowledge questionnaire so that they could be used on a larger scale. These modified assessment tools were then used on the 107 patients recruited at the dermatology clinic of the Centre Hospitalier Universitaire de Sherbrooke (CIUSSS de l’Estrie-CHUS) for comparative analyses. Results demonstrate a significant increase on the short-term eczema knowledge when comparing mean knowledge scores on the pre-test and post-test. On a general basis, there is no significant difference on the knowledge progression for the many demographic variables analysed (delta between pre-test and post-test mean scores). Also, knowledge progression between the different levels of health literacy is comparable. These results demonstrate a lack of impact of health literacy and other demographic variables on the studied assessment tools, which support their applicability on a larger scale.

Ultra wideband (UWB) technology plays a significant role in wireless communication. The complex antenna transfer function (CATF) of an UWB antenna provides important information required for better channel designs and communication systems. In this dissertation the CATF of a Double ridge guide horn (DRGH) antenna is determined and used as a standard antenna for UWB measurements. Two methods were used: the two antenna method in an anechoic chamber and a modified gain-transfer method in a compact antenna test range (CATR). Measurements were performed with a vector network analyser (VNA) in the frequency domain, in the anechoic chamber and the CATR. The distance measurements required to calculate the CATF from the S-parameter measurements were performed in the time domain. The CATF of the standard antenna was determined using two identical antennas and then it was shown that a modified gain-transfer method can be used to determine the CATF of any unknown antenna in a CATR, using the standard antenna as a reference. Some of the challenges were to obtain the correct equations and measurement method to obtain the CATF in a CATR. The standard antenna was used to investigate uncertainty contributions for the measurements in the CATR. / Dissertation (MEng)--University of Pretoria, 2013. / gm2014 / Electrical, Electronic and Computer Engineering / unrestricted

Le sujet de thèse abordé dans ce mémoire s'inscrit dans la thématique du LE²P sur l'autonomie énergétique des réseaux de capteurs. Ce travail est axé sur la partie réception et redressement du transfert de l'énergie sans fil pour l'apport d'énergie à des capteurs nomades. Ce procédé n'est pas nouveau et prend son origine dans les années 1950. Les connaissances dans l'appréhension de ce processus sont nombreuses pour certains guides d'onde tels que le microruban. Mais la nécessité de perçages dans ces structures de guide d'onde peut être contraignante et causer des disparités dans une chaîne de construction. Ceci a motivé les travaux présentés dans ce mémoire qui utilise une technologie de guide d'onde coplanaire (CPW) peu exploitée. Ainsi, la conception d'un tel dispositif passe par la maîtrise d'un point de vue conceptuel et expérimental de cette technologie. La démarche consiste à utiliser ce guide d'onde coplanaire en minimisant les effets négatifs que peut engendrer ce dernier, pour s'abroger du besoin de perçage et faciliter la réalisation des dispositifs de redressement en limitant le nombre d'interactions humaines. / The thesis subject dealt in this report lies in the LE²P framework on the energy sustainability of wireless sensor network. This work is dedicated to the reception and rectifying part of wireless power transfer to give energy sustainability to nodes in a sensor network. This process is not new and originate from the years 1950. The behavior of this process is since well-known in several waveguide such technology as microstrip. But the need of drill in those waveguide circuit may be inconvenient and lead to discrepancy from one circuit to another. This was the motivational keystone to the work address in this report which uses coplanar waveguide (CPW) over microstrip. The conception of such devices goes through a good conceptual and experimental understanding of the waveguide technology. The approach in this document consists of using coplanar waveguide while minimizing its drawbacks, in order to avoid drilling in the substrate and ease the realization of the rectifying part by limiting the human interaction.
