Today many companies aims to have their systems automated. Tieto works in a delivery system that is not fully automated, and they wish for it to be improved. They wish to improve this delivery system, as it’s not automated. This work aims to analyze the delivery system to find possi- ble solutions. The delivery system is being used to deliver services to Telia and developed modules are installed for system tests, acceptance tests and in production. The analysis is done by observing and interviewing users on Tieto. If a solution can be found the solutions will be found mainly within automation, but also in level of risk and usability. A solu- tion will be implemented and aiming for practical results that can be used in the delivery system. The analysis has resulted in prioritizing automa- tion of installations descriptions for modules, in the form of installation reports. After the automation of the installation reports, a prototype was implemented for automation of the installation guide. It is being used for getting an overview of everything that will be installed in production. A generation of installation reports has resulted in an automated solution that has been deployed in the delivery system. The deployment has shown a great time gain, a lower level of risk and an increased usability. The automation of the installation guide has resulted in a prototype that generates a big part of the content automatically. An analysis of the de- livery system shows that it contains both advantages and disadvantages in the system/process. It also contains a few missing parts. Many sugges- tions has been reported to improve the delivery system. / Idag strävar många företag till att få sina system automatiserade. Tieto jobbar i ett leveranssystem som inte är helt automatiserat och önskar att det förbättras. Arbetet syftar till att analysera leveranssystemet för att hitta möjliga lösningsalternativ. Leveranssystemet används för att leve- rera tjänster till Telia, och utvecklade moduler går därför igenom syste- met och installeras för systemtest, acceptanstest och till slut i produktion. Analysen ska genomföras med hjälp av att observera och intervjua an- vändare på Tieto under denna process. Om lösningsalternativ hittats ska förbättringar ske främst inom automatisering, men även inom risknivå och användarvänlighet. En lösning kommer implementeras och sträva ef- ter praktiska resultat som kan användas i leveranssystemet. Analysen har resulterat i att prioritet lagts på installationsbeskrivningar för moduler, i form av installationsrapporter. För att få en övergripande bild över allt som ska installeras ute i produktionen utformades även en installations- guide. Genereringen av installationsrapporterna har resulterat i en auto- matiserad lösning som blivit driftsatt i leveranssystemet. Driftsättningen har visat sig ge en stor tidsvinst, tillsammans med en minskad risknivå och en ökad användarvänlighet. Automatiseringen av installationsgui- den har resulterat i en prototyp som genererar stora delar av innehållet automatiskt. Analysen av systemet och processen visar att det både finns fördelar och nackdelar. Det finns även vissa delar som saknas. Flera för- slag har presenterats för att förbättra leveranssystem.

Introduction : À la suite d’une absence du travail en raison d’un trouble musculosquelettique (TMS), plusieurs travailleurs font un retour progressif au travail (RPAT). Cette pratique comporte plusieurs avantages, mais pose également des défis dans sa mise en application pour les entreprises. L’objectif de l’étude était d’offrir un outil adapté aux employeurs pour les soutenir dans la gestion des RPAT d’individus s’étant absentés en raison d’un TMS. L’étude poursuivait deux objectifs : 1) adapter un outil existant destiné aux professionnels de la réadaptation (Guide d’évaluation de la marge de manœuvre [MM]) et 2) en établir son acceptabilité auprès des utilisateurs potentiels (UP). Méthode : Un devis multiméthode a été utilisé et s’est actualisé en trois étapes. 1) La première étape consistait à adapter l’outil original en regard des résultats d’une revue critique de la littérature portant sur les caractéristiques favorisant l’adoption des guides par les UP. 2) La deuxième étape était de consulter un groupe d’experts en réadaptation au travail, familier avec le guide original et collaborant avec les UP, à l’aide d’une adaptation de la technique de recherche de l'information par l'animation d'un groupe d'experts (TRIAGE). Cette consultation s’est faite en deux phases : un sondage à compléter individuellement et une rencontre de groupe de consensus. Pour le sondage, un questionnaire auto-administré a été utilisé, avant la rencontre de groupe, pour établir le niveau d’accord des experts avec la pertinence, l’exhaustivité, la clarté, l’apparence visuelle et la convivialité de la première version de l’outil adapté. Des propositions ont été faites par les experts pour les énoncés ayant obtenu un score d’accord de deux ou moins et ont été traitées dans une rencontre de groupe, jusqu’à l’obtention d’un consensus sur les modifications à apporter. 3) La troisième étape visait à établir l’acceptabilité de la dernière version de l’outil adapté auprès des UP. Pour ce faire, des entrevues semi-dirigées ont été réalisées auprès de dyades composées de coordonnateurs de retour au travail et de supérieurs immédiats d’une même entreprise. Une analyse thématique du verbatim des entrevues a été réalisée. Résultats : 1) À partir de 13 publications, quatre grandes caractéristiques (clarté, format, applicabilité et utilité) ont été relevées de la revue critique. 2) Neuf ergothérapeutes (huit femmes et un homme, expérience moyenne de 12,17 ans) sont ensuite arrivés à un consensus de 20 modifications portant sur trois sections de l’outil adapté qui a mené à une deuxième version comportant un guide d’instructions de 22 pages et une grille de planification recto-verso. 3) Les 15 UP consultés (neuf femmes et six hommes provenant principalement de grandes entreprises de secteurs variés) ont globalement jugé l’outil acceptable. Ils ont reconnu, notamment, qu’il permettait d’opérationnaliser les bonnes pratiques de retour au travail, de standardiser la gestion des RPAT et d’inclure plus systématiquement le travailleur dans la démarche. Ils ont également identifié quelques changements mineurs à apporter, dont l’ajout de recommandations concernant la préparation des collègues et celui d’avoir un format plus court. Conclusion : Par l’adaptation du guide d’évaluation de la MM, cette étude a permis d’offrir un outil destiné et adapté aux employeurs, en tenant compte à la fois des données probantes et d’un consensus d’experts, ce qui semble avoir contribué à son acceptabilité par les UP. L’outil adapté comble un réel besoin au sein des entreprises et des études supplémentaires pourraient être menées pour améliorer son format et créer une version transdiagnostique. / Abstract: Purpose: To facilitate a return to work for workers being on a sick leave following a musculoskeletal disorder (MSD), many physicians prescribe a gradual return to work (GRTW), which poses numerous challenges for workplaces. The aim of this study was to provide employers with an adapted tool to support them in managing GRTWs following a MSD. The study had two objectives: 1) adapt an existing tool intended for rehabilitation professionals (Guide for estimation of margin of manoeuvre) and 2) establish the acceptability of the adapted tool with potential users (PUs). Methods: A mixed methods design was used and carried out in three phases. 1) The first step was to adapt the original tool by taking into account the results of a critical review of the literature on the characteristics fostering PU’s adoption of guides. 2) The second step was to consult a group of expert practitioners familiar with the original guide and who worked with the PUs, using an adaptation of the Technique for Research of Information by Animation of a Group of Experts (TRIAGE). This consultation was done in two phases: a survey to be completed individually, and a consensus group meeting. For the survey, a self-administered questionnaire was used, prior to the group meeting, to establish the level of agreement of the experts with the pertinence, exhaustiveness, clarity, visual appeal and user-friendliness of the first version of the adapted tool. The proposals made regarding statements that obtained mean agreement scores of two or less were then addressed in a group meeting, until consensus was reached on the changes to be made. 3) The third step was to establish the acceptability of the latest version of the adapted tool with the PUs. To do so, dyads composed of a return-to-work coordinator and a direct supervisor from the same company were interviewed, using a semi-structured interview guide. A thematic analysis of the verbatim transcript was performed. Results: 1) From 13 publications, four main characteristics (clarity, format, applicability, and usefulness) were identified from the critical review. 2) Nine occupational therapists expert (eight women and one man, mean experience of 12.17 years) reached a consensus on 20 modifications covering three sections, which yielded a second version of the adapted tool comprising a 22-pages instruction guide and a two-sided planning worksheet. 3) The 15 PUs consulted (nine women and six men mainly from large companies from various sectors) found the tool acceptable overall. They recognized that the developed tool allowed them to standardize the management of the GRTW, include the worker more systematically in the process, and operationalize the best return-to-work practices. They also identified a few minor changes to make, including recommendations for preparing colleagues and shortening the format. Conclusion: By adapting the Guide for estimation of margin of manoeuvre, this study provided a tool that was designed and adapted to employers, taking into account both evidence-based data and expert consensus, which seems to have contributed to its acceptability by PUs. The adapted tool fills a real need within companies and further studies could be carried out to improve its format and create a transdiagnostic version.

Specifically, a diagnosis was made in these IFES and a Sustainable Purchasing Guide was developed. Regarding the methodology, this research was characterized by being qualitative, applied nature, exploratory, bibliographic, documentary, and based on multicaso study. The research's diagnosis was developed based on data obtained from the Purchasing Panel of the Federal Government and Management Reports on sustainable public procurement developed between the years 2012 to 2017 in the IFES of the Center West of Brazil. After that, it was proposed to use the sustainable public procurement guide, which includes environmental, social, economic and political criteria. Among the results obtained, the diagnosis showed that the degree of maturity in all the IFES is initial, since the sustainable purchases still cover few products, little budget, and thus the proposed Sustainable Procurement Guide proved to be appropriate for UFG. Sustainable public procurement should be used as a public policy instrument to promote sustainable development, as well as foster innovation and reduce costs. / Este estudo refere-se a uma pesquisa desenvolvida sobre o tema Compras Públicas Sustentáveis e sua aplicação nas Instituições Federais de Ensino Superior do Centro Oeste. Especificamente foi realizado um diagnóstico nestas IFES e desenvolvido um Guia de Compras Sustentáveis. Quanto à metodologia, esta pesquisa caracterizou-se por ser qualiquantitativa, natureza aplicada, caráter exploratório, bibliográfica, documental, e baseada em estudo multicaso. O diagnóstico da pesquisa desenvolveu-se a partir de dados obtidos do Painel de Compras do Governo Federal e de Relatórios de Gestão sobre as compras públicas sustentáveis desenvolvidas entre os anos de 2012 a 2017 nas IFES do Centro Oeste brasileiro. Após isso, propôs-se a utilização do guia de compras públicas sustentáveis, que inclui critérios ambientais, sociais, econômicos e políticos. Entre os resultados obtidos, o diagnóstico demonstrou que o grau de maturidade nas IFES é inicial, vez que as compras sustentáveis ainda abrangem poucos produtos e pouco orçamento e, assim, o Guia de compras sustentáveis proposto mostrou-se apropriado para UFG. As compras públicas sustentáveis podem ser utilizadas como um instrumento de política pública para promover o desenvolvimento sustentável, além de fomentar inovações, e diminuir custos.

Quando um dente anterior é restaurado toda uma técnica de proteção ao tecido remanescente e a recuperação funcional do elemento dental podem ser comprometidas se a escolha da cor do material restaurador empregado não for adequada. A familiaridade com as teorias da cor e da interação da luz com a matéria pode ajudar na tarefa de escolha da tonalidade do material restaurador. O desafio na busca de um material restaurador ideal na sua função estética sempre foi obter a translucidez própria do esmalte dental. Contudo, essa translucidez faz com que o material restaurador sofra influência da cor de fundo, que pode ser da cor do material de proteção, ou mais normalmente da cor da dentina. No que tange as atividades de restauração estética odontológico, através deste trabalho foi possível concluir que: 1) A colorimetria pode ser um importante meio na seleção e na comunicação de tonalidades de materiais restauradores; 2) Os resultados obtidos confirmam que a cor de fundo exerce grande influência sobre a cor do resultado final da restauração; e 3) Os guias de tonalidade devem ser reformulados de tal forma que levem em consideração a espessura do material restaurador e a cor de fundo. / When an anterior tooth is restorated, the whole remaining tissue protection technique and functional recuperation of the dental element can be compromised if the choice of the color of the restorative material is not adequate. The familiarity with the color and light interaction with matter theories may help with the task of choosing the restorative material shade. The challenge in searching for an ideal restorative material in its esthetic function was always obtaining the proper translucency of dental enamel. However, this translucency makes the restorative material suffer an influence of the background color, which can be the protection material color or, more commonly, the dentine color. Concerning the odontologic esthetic restorative activities, it was possible to conclude from this work that: 1) Colorimetry can be an important way for the selection and communication of the restorative material shades; 2) The results show that the background color has a large influence on the final color of the restoration; and 3) The shade guides must be reformulated so that it take into consideration the thickness of the restorative material and background color.

O método desenvolvido utiliza lógicafuzzy e desvio padrão da declividade (Desvio padrão da declividade fuzzy - FuzDec) para o processamento de imagens e detecção de contorno. A detecção de contornos é uma tarefa importante para estimar características de escoamento bifásico através da segmentação da imagem das bolhas para obtenção de parâmetros como a fração de vazio e diâmetro de bolhas. FuzDec foi aplicado em imagens de instabilidades de circulação natural adquiridas experimentalmente. A aquisição das imagens foi feita utilizando o Circuito de Circulação Natural (CCN) do Instituto de Pesquisas Energéticas e Nucleares (IPEN). Este circuito é completamente constituído de tubos de vidro, o que permite a visualização e imageamento do escoamento monofásico e bifásico nos ciclos de circulação natural sob baixa pressão.Os resultados mostraram que o detector proposto conseguiu melhorar a identificação do contorno eficientemente em comparação aos detectores de contorno clássicos, sem a necessidade de fazer uso de algoritmos de suavização e sem intervenção humana. / t / IPEN/T / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP

Historicamente, o sistema para instalação de equipamentos de produção submarina de petróleo por meio de cabos guia, tem sua eficiência comprovada. Porém a grande maioria dos projetos das bases guia submarinas foi calculada por métodos analíticos, que embora permitam a obtenção de respostas exatas em todos os infinitos pontos de uma estrutura, não são aplicáveis a todos os casos. Isso motivou a aplicação do método dos elementos finitos (MEF) neste trabalho, que a partir do desenvolvimento de procedimentos aproximados, pode ser aplicado independentemente da forma da estrutura e das condições de carregamento. O estudo consiste da análise estrutural do modelo tridimensional da estrutura da base guia, modelado no software Autodesk Inventor e analisado no software ANSYS Workbench. O estudo traz uma pesquisa diagnóstica e utiliza abordagem quantitativa e exploratória. Diferentes modelos matemáticos foram gerados para obtenção dos resultados nos pontos mais críticos da estrutura, a fim de se determinar sua resistência aos esforços de instalação e operação aplicados, levando em consideração os critérios estabelecidos nas normas DNV No. 2.7-3, API 17D 1.ed. e a tensão equivalente de von-Mises. / Historically, the guideline system for installation of subsea oil production equipment has proven its efficiency. However the majority of the subsea guide base designs have been calculated by analytical methods, although they allow obtaining exact answers in all infinite points of a structure, they are not applicable to all cases. This motivated the application of the finite element analysis method (FEA) in this work, which from the development of approximate procedures can be applied regardless of the structure shape and loading conditions. This paper consists of a structural analysis of the guide base frame model, generated in Autodesk Inventor software and analyzed in ANSYS Workbench software. This study brings a diagnostic research using a quantitative and exploratory approach. Different mathematical models were generated to obtain the results at the most critical points of the structure in order to determine its resistance to the loads applied during installation and operation, taking into account the criteria laid down in DNV No. 2.7-3, API 17D 1st Ed. and the von-Mises equivalent stress.

ADHD have their signals observed in at least two of child living environments (home and school mostly). The disorder s prevalence is estimated in 5% of children. The children's school development is frequently affected by the disorder. This study aims to analyze the effects of behavioral management procedures in the classroom, in order to reduce behaviors of inattention and hyperactivity, using an intervention guide by the teacher. This work gone along with 64 students, from 6 to 12 years old, students of the 2nd and 4th year of a Center of Entire Education of Curitiba, consisting of 4 classes distributed two in an Experimental Group (EG) and two a Control Group (GC). The behavioral profile was assessed, using the CBCL/6-18 for parents and the TRF/6-18 for teachers that were applied before and after the intervention, along with a teacher's observation protocol with targets characteristic behaviors of the ADHD signs. The intervention guide was developed in previous works according to the basic principles of behavior analysis, was implemented with the classes through the teacher in a total of 28 weeks. The implementation guide was well accepted by the teachers who filled the weekly record in a Checklist on its implementation and participated in weekly support meetings. It was observed by teachers a reduced frequency behavior of inattention and hyperactivity in students in the classroom, through the responses of teachers to TRF/6-18 and the observation protocol, and also reported by parents in filling the CBCL/6-18. / O Transtorno do Déficit de Atenção e Hiperatividade (TDAH) é descrito pelo DSM-5 como um padrão persistente de desatenção e/ou hiperatividade-impulsividade que interfere no funcionamento ou no desenvolvimento. O TDAH deve ter seus sinais observados em pelo menos dois ambientes de convívio da criança (casa e escola principalmente). A prevalência do transtorno é estimada em 5% em crianças. O desenvolvimento escolar da criança é geralmente um dos que mais são prejudicados com o transtorno. O presente trabalho tem como objetivo analisar os efeitos de procedimentos de manejo comportamental em sala de aula, para redução de comportamentos de desatenção e hiperatividade, através de orientação ao professor e implementação de um guia de intervenção. Neste trabalho foi realizado o acompanhamento de 64 alunos, entre 6 a 12 anos, estudantes do 2º e 4º ano de um Centro de Educação Integral de Curitiba, constituídas por 4 turmas distribuídas duas em um Grupo Experimental(GE) e duas um Grupo Controle (GC). O perfil comportamental dos participantes foi avaliado utilizando o CBCL/6-18 para pais e o TRF/6-18 para os professores, que foram aplicados antes e após a intervenção, juntamente a um protocolo de observação do professor com comportamentos alvos característicos dos sinais de TDAH. O guia de intervenção foi elaborado em trabalhos anteriores segundo os princípios básicos da Análise do Comportamento, foi implementado junto às turmas por intermédio do professor em um total de 28 semanas. A implementação do guia foi bem aceita pelos professores que realizam o registro semanal em um Checklist sobre sua implementação e participaram de reuniões de acompanhamento e suporte semanal. Foi verificada, pelos professores, a redução da frequência de comportamentos de desatenção e hiperatividade nos alunos em sala de aula, por meio das respostas dos professores ao TRF/6- 18 e ao protocolo de observação, e também relatados pelos pais no preenchimento do CBCL/6-18.

Such condition often impairs the individual‟s educational process. This research aimed at developing and implementing behavioral management procedures in classroom context and assessing their effects in ADHD students. To do so, we resorted to the theory of Behavior Analysis. To assess the behavioral profile of participants, specific inventories were used (CBCL/6-18 for parents and TRF/6-18 and Benczik scale for teachers), as well as classroom observation based on a protocol elaborated by the researcher himself. Eight children participated in the study. All of them are Elementary School students from São Paulo and have been diagnosed with ADHD. A training program for teachers was elaborated to classroom behavioral management on the form of a Guide, which was used with four of the children (Experimental Group EG). Results were subsequently compared to Control Group (CG), formed by remaining four children. The Guide was based on the use of stimulus control strategies and reinforcers. The results show that observation sessions added by parents and teachers reports are significantly useful for establishing the participants‟ behavioral profile. When comparing EG and CG it was verified that most EG students had a decrease of the frequency of inattention and hyperactivity behaviors, which are incompatible with learning process at school; on the other hand, CG presented an increase in the frequency of such behaviors. These results indicate the efficiency of the Guide through simple changes in classroom procedures. After the implementation of these procedures it was verified, along the weeks, a gradual increase of its use by the teacher. We conclude that the application of the Guide, in the cases described in this work, has proved feasible and effective for the management of several behaviors related to inattention and hyperactivity, as well as of other behavioral problems commonly associated to ADHD. / O Transtorno do Déficit de Atenção e Hiperatividade (TDAH) é descrito, segundo o DSM-IV TR, como um padrão persistente de desatenção e/ou hiperatividade mais frequente e grave do que o observado em indivíduos de mesma faixa etária. Tal condição, muitas vezes, pode prejudicar o processo educacional dessas pessoas. O presente trabalho teve como objetivo desenvolver e implementar procedimentos de manejo comportamental no contexto de sala de aula e avaliar seus efeitos em alunos com TDAH. Para isso, foi utilizado o referencial teórico da Análise do Comportamento. Para avaliar o perfil comportamental dos participantes, foram utilizados inventários específicos (CBCL/6-18, para pais e TRF/6-18 e Escala Benczik de TDAH para professores), além de observação em sala de aula, a partir de um protocolo elaborado pelo próprio pesquisador. Participaram do estudo oito crianças do Ensino Fundamental da cidade de São Paulo diagnosticadas com TDAH. Foi elaborado um programa de treinamento com os professores para manejo comportamental em sala de aula, sob a forma de um Guia que foi aplicado em quatro dessas crianças (Grupo Experimental - GE). Os resultados foram posteriormente comparados ao grupo controle (GC), formado pelas outras quatro crianças. O Guia baseou-se na utilização de estratégias de controle de estímulos e de reforçadores. Como resultado, verificou-se que a realização de sessões de observação, somada aos relatos de pais e professores, trouxe grande contribuição para o estabelecimento do perfil comportamental dos participantes deste estudo. Ao se comparar o GE com o GC, verificou-se, na maioria dos alunos do GE, diminuição da frequência de comportamentos relacionados à desatenção e à hiperatividade, considerados incompatíveis com o processo de aprendizagem na escola; em contrapartida, no GC verificou-se aumento da frequência desses comportamentos. Tais resultados indicam a eficácia do Guia, mediante mudanças simples em procedimentos em sala de aula. Após a implementação desses procedimentos verificou-se, no decorrer das semanas, um aumento gradual na sua utilização pelo professor. Conclui-se que a aplicação do Guia, nos casos descritos neste trabalho, se mostrou viável e eficaz no manejo de diversos comportamentos relacionados à desatenção e à hiperatividade, assim como de outros problemas de comportamento comumente associados ao TDAH.

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.
