Un tokamak est le siège de diverses instabilités qui peuvent être à l'origine d'une dégradation du confinement magnétique. Cette thèse porte sur l'étude de la dynamique d'un îlot magnétique en présence de turbulence dans les plasmas magnétisés. Plus précisément, il s'agit de comprendre la nature de l'interaction multi-échelle entre la turbulence, générée par un gradient de pression et la courbure du champ magnétique, et un îlot magnétique formé par un mode de déchirement classique. Grâce à la déduction d'un modèle 2D prenant en compte ces deux sources d'instabilité, des études linéaires analytiques et numériques permettent de comprendre l'effet de la pression sur la phase de croissance linéaire d'un îlot magnétique et mettent en évidence la stabilisation des modes interchanges en présence d'un champ magnétique. Ensuite, des simulations non-linéaires du modèle sont présentées pour comprendre comment le mécanisme d'interchange affecte la dynamique non-linéaire d'un îlot magnétique. De façon générale, le gradient de pression et la courbure du champ magnétique affectent fortement l'évolution non-linéaire de l'îlot magnétique permettant l'apparition de bifurcations dynamiques dont la nature doit être caractérisée suivant les situations dans lesquelles on se place. Enfin, la dernière partie de cette thèse est dédiée à l'étude de la rotation poloïdale de l'îlot magnétique. La déduction d'un modèle permettant de mettre en évidence les différentes origines possibles de la rotation est présentée. Il apparaît clairement que la rotation non-linéaire de l'îlot magnétique peut être gouvernée par l'écoulement poloïdal E x B et/ou par l'écoulement non-linéaire diamagnétique.

The paper describes a layout and a development of the software product used for fully automatic data exchange and synchronization between a business information system (ERP system) and a web system (an e-shop). The reason for designing such a system is an effort to minimize human work performed when handling the data in both systems. The data integrity in both systems is established due to this mechanism and a significant time saving is likewise a key factor. If the data are changed in one system, the changes are detected and synchronized with the data from the other system which constantly ensures up to date data.

Atualmente, a Tranferência Eletrônica de Dados (EDI) é considerada uma ferramenta de fundamental importância para o processo de comunicação entre as organizações. Esta tecnologia permite fornecedores e varejistas responderem às necessidades do mercado consumidor de forma mais eficiente, rápida e precisa. Embora muitos autores tenham mostrado o potencial desta tecnologia para a obtenção de resultados, e de sua crescente utilização, há polêmica sobre seu desempenho quando é utilizado na realidade. Este trabalho é iniciado com a procura de um conjunto teórico de características operacionais que tenham correlação com um conjunto de resultados esperados pela sua utilização. Esta tarefa foi feita através da revisão da literatura relacionada com o assunto. A pesquisa das correlações, comuns ao conjunto de organizações, que conflitam com as previstas pela literatura foi efetuada entre os fornecedores de supermercados, localizados em São Paulo, e identificou sete casos. Estas informações podem auxiliar as organizações a promover mudanças comportamentais e na estrutura de seus processos, para melhorar os resultados do uso desta tecnologia. O trabalho sujere explicações para estas diferenças, e propõe pesquisas posteriores para confirmá-las. / Nowadays, Eletronic Data Interchange is considered an important tool for the communication process among organizations. Linking suppliers and retailers, this technological apparatus allow companies to answer more efficiently, faster and precisely, the consumer market requirements. Although many studies have shown the potential advantages of EDI and its use has increased as well, there are not clear evidences about its effective results on promoting better results for business activities. This work starts trying to settle the main theoretical propositions related to the impacts, on performance, of a frequent business characteristics set. These features are pointed out based on literature revision. The identification of common correlations in a researched population that conflicts with the theoretical previsions was carried out, and pointed seven of these cases. These may help organizations in promoting changes in person's behavior and process structure, towards the improvement of results. Suggested explanations for these divergences are considered. Propositions for further researches in this conflict area are issued.

The innovative advancements of information communication technology (ICT) combinedwith a globalized economy have given rise to organizational forms that manipulate timeand distance. Today, competitive advantages are more elusive than tangible as a result ofdynamically complex environments motivating organizations to adjust in structure andfunctional capacity. New emergent forms of organizational structures have resulted inthe virtual organization (VO), which employs a network structure and allowsorganizations the flexibility to perform core processes amongst distributed teams, units,departments, and/or organizations. In essence the virtual organization may be viewed asa strategic response to dynamic environmental forces that have encouragedorganizations to rethink the concept of competitiveness. Virtual organizations havegained popularity throughout the last decade as a more effective way of managing andcommunicating information within and across organizations. Information communicationtechnology (ICT) has aided in the globalizing effect of informationalism. Theinformational flows within a virtual organization have direct bearing on individual andgroup efforts to obtain and employ information essential to organizational objectives.This thesis investigates the information interchange within virtual organizations througha theoretical study, which converges identified relevant subject areas and introduces theMedia Rich Social Information Interchange (MERiSii) model. The empirical study isdesigned to further investigate the validity of theoretical concepts employed in theMERiSii model and to expand its development to facilitate the function of informationinterchange. VGR-IT is an IT infrastructure provider, for hospitals and healthcarefacilities in the Västra Götaland region of Sweden. Interviews conducted with an accountmanager for VGR-IT and an IT strategist for Borås Hospital give insight into thecommunicative tasks of information interchange that must be effective to support the coreprocesses within VGR-IT and the service VGR-IT provides to Borås hospital. The resultsof a comparative analysis between the theoretical and empirical studies support a revisedMERiSii model that may be implicated in future research to further verify itseffectiveness. / Program: Magisterutbildning i informatik

This thesis establishes an empirically based dialogue between two theoretical approaches to management, one emphasing structure and the other process, by examining the question of whether management in private sector, profit oriented organizations is similar to, or different from, management in government departments. Subjects for the study were participants in the Australian Public Service (APS) Interchange Program, under which APS members work temporarily in other organizations, and managers from outside the Service spend some time in the APS. The measuring instruments used were a questionnaire designed to test empirically and to extend research by Fottler (1981), a standardised measure of personal values and two questionnaires to gather personal details and job related information pertinent to the parent and host organizations. The results of the study indicate that Interchange participants found significant differences between the Service and the private-for-profit organizations in which they worked. The differences within the major structural variable, organization type, can be expressed in terms of managerial processes. Evidence was found of interrelationships between organization type, job related process variables and personal values. The theoretical significance of these results is discussed in terms of a pluralistic approach to managerial process, the practical implications for the APS are noted, and suggestions for further research are proposed.
