Relations between national culture dimensions the supplier integration in the product-process-supply chain triad: case study of the modular consortium / Relações entre as dimensões da cultura nacional e a integração do fornecedor na tríade produto-processo-cadeia de suprimentos: estudo de caso do consórcio modularFausto Perez Rodrigues 13 October 2015 (has links)
In the rapid pace of globalization and new market competition, the New Product Development (NPD) and the Supply Chain Management (SCM) represent today a frontier to obtain competitive advantages to companies. One interface between NPD and the SCM, the Supplier Integration (SI) has proved to be effective as competitive advantage. However, there is a lack of research on how human variables, such as national culture, can moderate the effectiveness of Supplier Integration on those fields. Therefore, this study investigates the relationships between Supplier Integration from the Product-Process-Supply Chain triad and the National Culture Dimensions. I conducted an exploratory case study in 3 companies in the automobilist industry that operates as a Modular Consortium (MC) in Southern Brazil and used the Hofstede´s (2001) national culture dimensions to model national cultural factors. The findings show an evident relation between Supplier Integration with the Low Power Distance, Low Individualism and High Uncertainty Avoidance poles, while no Masculinity and Longterm Orientation pole was distinct for the Supplier Integration in the case study. The managerial implications of this study is to provide a better understanding of the potential impact of human factor to the Supplier Integration in companies that will have operations in Brazil. / No ritmo acelerado da globalização e nova concorrência no mercado, Desenvolvimento de Novos Produtos (NPD) e Supply Chain Management (SCM) representam hoje uma fronteira para obter vantagens competitivas para as empresas. Uma interface entre o NPD e o SCM, a Integração do Fornecedor (SI) provou ser eficaz como vantagem competitiva. No entanto, há uma falta de investigação sobre como variáveis humanas, tais como cultura nacional, pode moderar a eficácia da integração do fornecedor (SI) nesses campos do conhecimento. Portanto, este estudo investiga as relações entre fornecedor Integração da Cadeia na tríade Produto-Processo-Cadeia de Suprimentos e as Dimensões da Cultura Nacional. Para tal foi realizado um estudo de caso exploratório em três empresas do setor automobilístico que operam no Consórcio Modular (MC) no Sudeste do Brasil e usaram-se as dimensões culturais de Hofstede\'s (2001) para modelar fatores humanos. Os resultados mostram uma evidente relação entre a integração do fornecedor com a baixa Distância do Poder, baixo Individualismo e elevada Aversão à Incerteza, no entanto não foram obtidas relações evidentes para as dimensões Masculinidade e Orientação a Longo Prazo para a Integração do Fornecedor no estudo de caso. A principal colaboração deste trabalho é o fornecimento de uma melhor compreensão do potencial impacto do fator humano para a integração do fornecedor em empresas que possuem operações no Brasil.

O sistema modular de ensino no Estado do Pará : contribuição para o desenvolvimento educacional no município de Abaetetuba / Modular System of education in the Pará State: contribution to the educational development of the city of AbaetetubaAldeíse Gomes Queiroz 25 May 2010 (has links)
Objetivou-se, neste estudo, analisar de que forma as estratégias desenvolvidas no Sistema de Organização Modular de Ensino - SOME contribuem para o desenvolvimento educacional no município de Abaetetuba, no Estado do Pará. O SOME é um programa gerido pela Secretaria de Educação desde 1982, como alternativa de atendimento e expansão do Ensino Médio presencial no interior do Estado, com metodologia curricular diferenciada do ensino regular, por meio de módulos, para oferecer oportunidade de estudo aos educandos egressos do ensino fundamental que não têm possibilidades de se transferirem para locais onde possam cursar o Ensino Médio, devido às características geográficas onde se localiza o município objeto deste estudo. Para a coleta de dados o instrumento foi entrevista individual semiestruturada junto a gestores, professores e alunos que participam do programa. Foi efetuada análise de conteúdo, para possibilitar maiores entendimentos sobre o programa implantado no município. O método utilizado foi descritivo, e os dados foram tratados de forma qualitativa e quantitativa. Os principais fatores que justificam a contribuição do SOME para o desenvolvimento educacional na comunidade de Abaetetuba são possibilidades de aumento da escolaridade, maiores perspectivas de ingresso no mercado de trabalho e conseqüente geração de renda. / This study aimed to analyzed how the strategies used in System of Modular Organization of Education SOME contribute to the educational development of the municipality of Abaetetuba, Pará. SOME is a program ran by the State Agency for Education since 1982 as an alternative to expand the high school system in inner cities of the state to offer the students who are not able to go to bigger cities an opportunity to continue their education. For data collection we used a semi-structured interview with managers, teachers and students who participate in this program. We analyzed the content of those interviews to enable a better understanding about the program in this municipality. Our method was descriptive and the data were analyzed in both quantitative and qualitative ways. The main factors pointed by our subjects as the contribution of SOME to the development of Abaetetubas community were: an increase in the number of students, perspectives of better jobs and a subsequent increase in the income generation. Even though SOME contributes for the employability of the graduates, it does not guarantees the quality of those jobs.

Vector-Valued Mock Theta FunctionsWilliams, Clayton 01 August 2022 (has links)
Ramanujan introduced his now celebrated mock theta functions in 1920, grouping them into families parameterized by an integer called the order. In 2010 Bringmann and Ono discovered generalizations of Ramanujan's mock theta functions for any order relatively prime to 6; this result was later strengthened by Garvan in 2016. It was also shown that by adding suitable nonholomorphic completion terms to the mock theta functions the family of mock theta functions corresponding to a given order constitute a complex vector space which is closed under the action of the modular group. We strengthen the Bringmann, Ono, and Garvan result by constructing a vector-valued modular form of weight 1/2 transforming according the Weil representation for orders greater than 3 by introducing an algorithm which simultaneously numerically constructs the form and proves its transformation laws. We also explicitly construct the 7th order form and prove analytically that it has the proper modular transformations. It is conjectured the same method will apply for other orders.

Vibration Serviceability Assessment of a Steel Modular Floor SystemMercado Celin, Maria Angelica 14 August 2023 (has links)
A new modular steel floor system, named FastFloor, is proposed for commercial buildings. The system is conceptualized to be prefabricated at the shop and ready to be installed on a previously erected skeleton frame structure consisting of girders and columns or connected to core shear walls. The system configuration aims to increase the speed of design, fabrication, and erection of a steel project by eliminating concrete pouring and curing times. Other advantages include reducing the weight of the building and its carbon footprint.
Several module configurations were considered and evaluated based on a series of interviews with experts in steel fabrication and erection engineering. The selection relied not only on addressing the issues related to fabrication, transportation, and erection but also on satisfying floor vibrations, as it was determined to be the governing limit state of the plate thickness, section sizes, and beam spacing due to the presence of an unstiffened bare plate acting as a slab. Observations were performed regarding fabrication sequence and transportation on the chosen configuration.
The dynamic properties of the module are particularly important because DG11 was developed for composite concrete-steel floor systems, and its applicability to all steel-floor systems needs to be evaluated. In parallel, a vibration testing program was conducted to determine the dynamic properties of the module, including natural frequencies and mode shapes. Lastly, the acceptability of the modular system for floor vibrations was evaluated by both a calculation method and a modeling approach. The analysis results suggest that the module will not satisfy floor vibrations criteria, but a modified module with added stiffeners is shown to be acceptable. Upcoming tests, by others, on specimens with a raised access floor will be necessary to refine the predictions and determine if the stiffeners are actually required. / Master of Science / FastFloor is an innovative modular all-steel floor system that aims to revolutionize the construction of commercial buildings, with benefits including enhanced efficiency in design, fabrication, and erection, as well as reduced environmental impact, by eliminating the need for concrete pouring and curing and full prefabrication in shops.
Several module configurations were evaluated based on insights from industry experts in steel fabrication and erection engineering. It was observed that the main challenge in the early phases was to address issues related to fabrication, transportation, and erection while ensuring optimal performance in terms of floor vibrations.
This thesis project focused on a preliminary assessment of the vibration behavior of the system by conducting dynamic tests and evaluating the compatibility with the analytical and computational procedures in Design Guide 11, which is not calibrated for an all-steel system like FastFloor.
Based on the results, it was concluded that the initial configuration did not fully satisfy the floor vibrations criteria. However, through further computational evaluation, a modified module, based on the initial configuration with added stiffeners, was predicted to be satisfactory. Thus, future research will continue to refine the system behavior and predictions and evaluate the contributions of Raised Access Floor to the vibration performance.

Images des représentations galoisiennes / Images of Galois representationsAnni, Samuele 24 October 2013 (has links)
Dans cette thèse, on étudie les représentations 2-dimensionnelles continues du groupe de Galois absolu d'une clôture algébrique fixée de Q sur les corps finis qui sont modulaires et leurs images. Ce manuscrit se compose de deux parties.Dans la première partie, on étudie un problème local-global pour les courbes elliptiques sur les corps de nombres. Soit E une courbe elliptique sur un corps de nombres K, et soit l un nombre premier. Si E admet une l-isogénie localement sur un ensemble de nombres premiers de densité 1 alors est-ce que E admet une l-isogénie sur K ? L'étude de la repréesentation galoisienne associéee à la l-torsion de E est l'ingrédient essentiel utilisé pour résoudre ce problème. On caractérise complètement les cas où le principe local-global n'est pas vérifié, et on obtient une borne supérieure pour les valeurs possibles de l pour lesquelles ce cas peut se produire.La deuxième partie a un but algorithmique : donner un algorithme pour calculer les images des représentations galoisiennes 2-dimensionnelles sur les corps finis attachées aux formes modulaires. L'un des résultats principaux est que l'algorithme n'utilise que des opérateurs de Hecke jusqu'à la borne de Sturm au niveau donné n dans presque tous les cas. En outre, presque tous les calculs sont effectués en caractéristique positive. On étudie la description locale de la représentation aux nombres premiers divisant le niveau et la caractéristique. En particulier, on obtient une caractérisation précise des formes propres dans l'espace des formes anciennes en caractéristique positive.On étudie aussi le conducteur de la tordue d'une représentation par un caractère et les coefficients de la forme de niveau et poids minimaux associée. L'algorithme est conçu à partir des résultats de Dickson, Khare-Wintenberger et Faber sur la classification, à conjugaison près, des sous-groupes finis de $\PGL_2(\overline{\F}_\ell)$. On caractérise chaque cas en donnant une description et des algorithmes pour le vérifier. En particulier, on donne une nouvelle approche pour les représentations irréductibles avec image projective isomorphe soit au groupe symétrique sur 4 éléments ou au groupe alterné sur 4 ou 5 éléments. / In this thesis we investigate $2$-dimensional, continuous, odd, residual Galois representations and their images. This manuscript consists of two parts.In the first part of this thesis we analyse a local-global problem for elliptic curves over number fields. Let $E$ be an elliptic curve over a number field $K$, and let $\ell$ be a prime number. If $E$ admits an $\ell$-isogeny locally at a set of primes with density one then does $E$ admit an $\ell$-isogeny over $K$? The study of the Galois representation associated to the $\ell$-torsion subgroup of $E$ is the crucial ingredient used to solve the problem. We characterize completely the cases where the local-global principle fails, obtaining an upper bound for the possible values of $\ell$ for which this can happen.In the second part of this thesis, we outline an algorithm for computing the image of a residual modular $2$-dimensional semi-simple Galois representation. This algorithm determines the image as a finite subgroup of $\GL_2(\overline{\F}_\ell)$, up to conjugation, as well as certain local properties of the representation and tabulate the result in a database. In this part of the thesis we show that, in almost all cases, in order to compute the image of such a representation it is sufficient to know the images of the Hecke operators up to the Sturm bound at the given level $n$. In addition, almost all the computations are performed in positive characteristic.In order to obtain such an algorithm, we study the local description of the representation at primes dividing the level and the characteristic: this leads to a complete description of the eigenforms in the old-space. Moreover, we investigate the conductor of the twist of a representation by characters and the coefficients of the form of minimal level and weight associated to it in order to optimize the computation of the projective image.The algorithm is designed using results of Dickson, Khare-Wintenberger and Faber on the classification, up to conjugation, of the finite subgroups of $\PGL_2(\overline{\F}_\ell)$. We characterize each possible case giving a precise description and algorithms to deal with it. In particular, we give a new approach and a construction to deal with irreducible representations with projective image isomorphic to either the symmetric group on $4$ elements or the alternating group on $4$ or $5$ elements.

Previous issue date: 2016-03-04 / Agência Nacional do Petróleo, Gás Natural e Biocombustíveis / Computer modeling of reservoirs is the tool that provides the accurate description of the existing physical phenomena in the oil and gas recovery process, being of interest to both the industry and science. In oil and gas industry, the demand of commercial simulators is remarkable. At the same time, scientific simulators are able to provide researchers with the freedom and control needed by the academic activity.
Among the major demands of scientific software are: (i) the scalable design, which is correlated with organized and modular code development, and (ii) the scalable execution, related to the implementation of techniques for parallel and high performance computing, due to the large amount of manipulated data and the compute-intensive numerical models produced by science.
This dissertation aims to the application of techniques for modular object-oriented programming and parallel computing, with OpenMP and MPI, in a scientific simulator, developed in Fortran and used in the numerical modeling of problems related to gas flow on unconventional gas-shale reservoirs. / A modelagem computacional de reservatórios é o instrumento que permite a descrição precisa dos fenômenos físicos existentes no processo de recuperação de óleo e gás, tendo grande interesse tanto para a indústria quanto para a ciência. Na indústria de óleo e gás, é grande a demanda por simuladores comerciais de reservatórios. Por outro lado, simuladores científicos são capazes de oferecer aos pesquisadores do domínio, o controle e a liberdade necessários à atividade acadêmica.
Dentre as principais demandas do software científico em geral estão (i) o design escalável, relacionado ao desenvolvimento de código de maneira organizada e modular, contribuindo para sua evolução e (ii) a execução escalável, relacionada à implementação de técnicas de computação paralela e de alto desempenho, em razão das grandes massas de dados manipuladas e dos modelos numéricos computacionalmente intensivos produzidos pela ciência.
Este trabalho trata do emprego de técnicas de programação modular com orientação a objetos e de computação paralela com OpenMP e MPI em um simulador científico, escrito em Fortran e utilizado na modelagem numérica de problemas de escoamento em reservatórios não convencionais de gás em folhelhos.

Estudo comparativo entre os fornecedores de componentes automotivos de plantas convencionais e modulares. / A comparative study between the suppliers of automotive components to conventional and to modular plants.Graziadio, Thaise 16 August 2004 (has links)
O objetivo desta tese é verificar se, e como a Estratégia Modular implementada por uma montadora de automóveis influencia os fornecedores de componentes que ocupam o 2º. nível da cadeia de suprimento modular. A estratégia visa aumentar a eficiência e a rentabilidade da produção e do negócio, e integra ações para reduzir custos e aumentar a produtividade através de montagem final em módulos, e para reduzir riscos do investimento via externalização de atividades de produção e projeto para os fornecedores. O método estudo de caso foi utilizado na análise de duas cadeias produtivas (mesma montadora), uma convencional e outra modular, e que produzem carros semelhantes. Foram selecionados dois módulos de cada carro: suspensão e cockpit. Em cada cadeia, foram estudados dois níveis de fornecedores: 1º. (ou sistemistas) e 2º. (fornecedores de componentes). Comparada à convencional, a organização modular se caracteriza pelo fluxo físico consolidado (de conjuntos e módulos), pela redução de número de fornecedores diretos da montadora, e criação de um nível intermediário, o do sistemista (fornecedor de módulo), entre outros. De modo amplo, os fornecedores sistemistas assumem atividades da produção, projeto e gestão de fornecedores, antes exclusivas da montadora, além de se instalarem perto da linha final. Entretanto, a pesquisa revelou dois tipos de sistemistas: montador, que gerencia compras de peças, monta os módulos e os entrega na linha final participação (atuação em projeto muito limitada) e o integrador que participa do projeto dos componentes (desde o conceito do produto até a produção), coordena técnica e comercialmente os fornecedores para que preços, prazos de entregas e qualidade estejam em conformidade, e garante a funcionalidade do módulo. A estratégia modular da montadora afeta, embora menos, os fornecedores nível 2, sendo que as mudanças são mais fortes para os que fornecem para o sistemista integrador pois a chance de perder contato direto com a montadora é maior e, junto, se perde acesso a novos projetos, melhorias tecnológicas e oportunidades rentáveis. O maior valor agregado ao produto do sistemista e a externalização causam várias mudanças de produto, processo e relações de suprimento entre o integrador e o nível 2. Quanto ao fornecedor do sistemista montador, as mudanças se concentram basicamente em logística e gestão da qualidade. / The objective of this dissertation is to verify and to understand how does the modular strategy being implemented by the car assembler influences the suppliers in the 2nd. level of the automotive chain. Modular strategy is conceptually based on modularity (more added value to components as they become modules) and outsourcing (suppliers involvement in activities usually made only by the assembler). Method case was used in the analysis of two productive chains of a single assembler, one is conventional and the other is modular, producing similar subcompact cars. We studied two modules of each car: suspension and cockpit. Each chain is composed of one car assembler, some 1st. tier suppliers (also called systemists or module suppliers) and some 2nd. tier suppliers (the components producers). The modular organization characterizes for the consolidated physical flow (assemblies and modules), the reduction of direct suppliers to the assembler, and the new role of the module suppliers. We found two kinds of modular supplier: first one is the 'assembler systemist' and it basically purchases the components of the module, assembles it and deliveries it at the final assembly line. The other type is the 'integrator systemist', to whom the changes are more significant. The 'integrator systemist' assumes relative responsibilities for development and many responsibilities for production and supply management. Generally speaking, the second tier suppliers (producers of components) are not very influenced by the Modular Strategy but when we consider the differences among the module suppliers, several points are distinguished. Effects of modularization and outsourcing are more intense on the second tier suppliers that work for the 'integrator systemist', since they face changes in the components development, in commercial practices, in productive processes and also in the supply system.

Previous issue date: 2015-05-22 / Nenhuma / Embora existam investigações teóricas e empíricas sobre consórcio modular, estudos sobre as relações entre os modulistas, o fluxo de informações e a Gestão Interorganizacional de Custos (GIC) em arranjos de consórcio modular são embrionários. O consórcio modular e a GIC induzem as empresas a ultrapassar as fronteiras organizacionais, no intuito de permitir que toda a cadeia de valor se torne mais eficiente. A presente tese, configurada com um Estudo de Caso com Objetos Incorporados, defende a possibilidade de aceitação que a associação entre consórcio modular e GIC promove mútuo aprendizado e maior redução dos custos globais de operações na cadeia de valor automobilística, do que adotadas isoladamente. Entende-se que as abordagens adotadas pelo consórcio modular de Resende (modularização e GIC) são complementares e incluem diversos fatores comuns, tal como a partilha de projetos de P&D, entrosamento de seus funcionários em outras empresas, sistemas integrados de informações, transferência de conhecimento, bem como a necessidade de desenvolvimento de uma gestão interorganizacional mais eficiente. Neste contexto, o consórcio modular constitui-se em um elemento facilitador do processo de GIC, pois o custo admissível dos componentes é definido por equipes interorganizacionais de trabalho, que incluem design de produto, engenharia, compras e engenharia de produção. Assim, as empresas demonstram possuir uma relação de alta interdependência. Porém resta evidente que, nem sempre, os benefícios são compartilhados entre todos os atores envolvidos, em função da assimetria de poder entre a MAN e os modulistas. No que tange à troca de informações de custos os achados indicam forte ocorrência desta iniciativa, porém somente dos modulistas para a MAN. As evidências empíricas obtidas no presente estudo denotam o uso de poder pela MAN aos seus modulistas. O uso do poder pode favorecer a divulgação de dados de custos pelos modulistas, mas isso não garante o êxito da GIC em toda sua plenitude. Essa é uma limitação para a aplicabilidade da GIC através do open book accounting. / Although there are theoretical and empirical research on modular consortium, studies on the relationship between modulists, the flow of information and the Interorganizational Cost Management (IOCM) in modular consortium arrangements are embryonic. The modular consortium and IOCM induce companies to overcome organizational boundaries in order to allow the entire value chain becomes more efficient. This thesis, configured how a Case Study with Embedded Objects, defends the possibility of accepting that the association between modular consortium and IOCM promotes mutual learning and further reducing overall operating costs in the automotive value chain, rather than taken alone. It is understood that the approaches adopted by the modular consortium in Resende (modularization and IOCM) are complementary and include several common factors, such as the sharing of R&D projects, meshing of its employees in other companies, integrated information systems, knowledge transfer as well as the need to develop a more efficient inter management. In this context, modular consortium is on a facilitator of the IOCM process because the allowable cost of the components is defined by inter-working teams, which include product design, engineering, procurement and production engineering. Thus, companies have shown a high interdependent relationship. But it is evident that not always, the benefits are shared between all the actors involved, due to the asymmetry of power between MAN and modulists. Regarding the exchange of the findings indicate a strong occurrence cost information of this initiative, but only the modulists for MAN. The empirical evidence obtained in this study denote the use of power by MAN to its modulists. The use of power may favor disclosure by modulists cost data, but this does not guarantee the success of IOCM in all its fullness. This is a limitation to the applicability of IOCM through open book accounting.
