The terminations and the joints are the basic accessories of the power cables. Power cables require electrical stress control when terminated. Since there are different types of terminations, the analysis should be done to choose the proper method for electric field control problem at the terminations. Throughout this study two different types of termination methods are investigated by using the finite element analysis program (ANSYS): Stress Controlled Termination Model with Deflector and Stress Control Tube (SCT). The results are compared with those obtained for a cable without stress control model termination. The numerical calculations are also compared with the measurements obtained by an experimental model: the electrolytic tank model.

The objective of my work has been to monitor the opinions of social workers operating within the departments of social and legal protection of children at village municipalities with an extended scope of authority in the South Bohemian region as related to the problems of child care and education in substitute family care from the perspective of a social worker. The second objective has been to map the situation of children registered by the departments of social and legal protection of children of South Bohemia, the substitute family care of which was terminated before the 18th year of child´s age during the years 2003 {--} 2009. Due to significant reasons substitute family care, with the exception of adoption, can be terminated earlier. This presents a difficult situation both for the foster parents and for the foster children put into substitute family care. The results of my work have shown that most social workers do not lack the assistance of professional facilities that would support foster families in their regions. The most common reason for the termination of substitute family care before the 18th year of child´s age have been educational problems involving a whole range of issues. For most children, the termination of substitute family care resulted in institutional care {--} youth educational centers.

In this article, the author analyses whether Peruvian labor law permit the incorporation of a resolutive condition in undetermined contracts of employment. To do so, the author annotates a particular case of Peru, as well as some judgments of the Spanish Court of Justice. / En el presente artículo, la autora analiza si a la luz de las normas laborales que regulan las causales de extinción de los contratos de trabajo, es posible que las partes puedan incorporar válidamente una condición resolutoria en contratos a plazo indeterminado. Para ello, comenta un caso particular peruano, así como algunos pronunciamientos del Tribunal Supremo español.

With this study the status of “non-fixed indefinite” in the service of the government workers is analyzed. The “no permanent fixed” are those workers who although initially had a temporary contract with an administration, it has become indefinite due to irregularities thereof. Analyze how Spanish jurisprudence has tried to strike a balance between labor interests (of job security) and public (the constitutional principles of equality, merit and ability in access to public service). / Con este estudio, se analiza la situación jurídica de los trabajadores “indefinidos no fijos” al servicio de las Administraciones Públicas, es decir, aquellos que si bien, inicialmente, tenían un contrato de carácter temporal, éste se ha convertido en indefinido como consecuencia de las irregularidades del mismo. Analizaremos, cómo la jurisprudencia española ha intentado establecer un cierto equilibrio entre los intereses laborales (de estabilidad en el empleo) y los públicos (los principios constitucionales de igualdad, mérito y capacidad en el acceso a la función pública).

The first one has as the main result that the mobile termination rates will be set bellow the marginal cost to end a call. But the reality shows that the mobile termination rates are too high and the regulators faces a lot of constrains when they try to bring down the level of those rates, because the mobile networks oppose to those policies. This work develops a model based on Hoernig (2010) that presents more realistic results. It will use a new assumption: the mobile networks will compete at the same market with a fixed network and this last one will have its prices regulated. This is a plausible assumption considering the actual development of the mobile networks. The model has two frameworks: at the first there is any kind of shared control between one of the mobile and fixed telephony, but at the second that shared control exists. Because of the assumption that the mobile and fixed networks will compete, this work has as general result that the mobile networks will set the mobile termination rates above the marginal cost of terminating a call. / Existe uma dissonância entre a teoria dominante de competição entre telefonias e evidências empíricas. Aquela tem como resultado que as redes de telefonia móvel irão definir a tarifa de interconexão abaixo do custo marginal de término da ligação. Já evidências empíricas diversas mostram que as tarifas de interconexão das telefonias móveis são mais elevadas e que as agências reguladoras encontram resistência destas ao aplicarem políticas de redução das tarifas de interconexão. Este trabalho desenvolve um modelo, baseado em Hoernig (2010), que provê resultados mais aderentes às evidências de existência de incentivos para precificação de tarifas de interconexão acima do custo marginal. O modelo aqui proposto inova em relação a Hoernig (2010) ao assumir que as redes de telefonia móvel concorrem com a telefonia fixa, a qual é sujeita à regulação da tarifa de interconexão. Esta é uma representação bastante plausível frente ao desenvolvimento da telefonia móvel. O modelo também considera o efeito de uma das empresas de telefonia móvel ter o seu controle compartilhado com a de telefonia fixa. Devido ao pressuposto de competição em um mesmo mercado entre telefonia fixa e móvel, é encontrado como resultado geral que as redes de telefonia móvel irão definir a tarifa de interconexão acima do custo marginal de término da ligação.

Ce travail de thèse est consacré à la conception et à la fabrication de diodes JBS en carbure de silicium. Une première partie de ce travail a consisté à concevoir par simulation une protection périphérique de la diode la plus efficace possible en réduisant sa sensibilité à la technologie (charges dans l’oxyde et activation des dopants). L’impact de la géométrie de l’anode de la diode JBS sur le champ électrique maximum sous le contact Schottky en inverse et la résistance série de la diode à l’état passant a été étudié. Une nouvelle architecture de diode JBS, à base de tranchées implantées, a été proposée pour pallier les limitations liées aux faibles profondeurs d’implantation d’Al. Une deuxième partie de ce travail a concerné le développement de briques technologiques, indispensables à la fabrication de la diode JBS, tels que les contacts métalliques et la gravure. Enfin, la fabrication complète et la caractérisation électrique de diodes ont été réalisées afin de valider les éléments de conception et l’intégration des briques technologiques développées durant cette thèse. / This study was dedicated to the design and to the fabrication of SiC JBS diodes. The first part of this work includes the design of robust efficient edge termination of the diode with special care to its technology sensitivity. The impact of anode layout of JBS diode on the maximum electric field under Schottky contact and on the on-state resistance has been investigated. A new structure of JBS diode, trenched and implanted, has been proposed to overcome the low Al implantation depth. A second part of this work has been focused on the development of technological steps required for the fabrication of JBS diodes such as metal contact and SiC etching. Finally, full fabrication and electrical characterization of diodes have been carried out in order to validate the design and the integration of technological steps developed during this thesis work.

Dans cette thèse, nous présentons des approches formelles permettant de simplifier la modélisation et la preuve du calcul distribué. Un système distribué est défini par une collection d’entités de calcul autonomes,qui communiquent ensemble pour accomplir une tâche commune. Chaque entité exécute localement son calcul et ne peut interagir qu’avec ses voisins.Le développement et la preuve du calcul distribué est un défi qui nécessite l’utilisation de méthodes et outils avancés. Dans nos travaux de thèse,nous étudions quelques problèmes fondamentaux du distribués, en utilisant Event-B, et nous proposons des schémas de preuve basés sur une approche“correct-par-construction”. Nous considérons un système distribué défini par réseau fiable, de processus anonymes et avec un modèle de communication basé sur l’échange de messages. Dans certains cas, nous faisons abstraction du modèle de communications en utilisant le modèle des calculs locaux. Nous nous focalisons d’abord sur le problème de détection de terminaison du calcul distribué. Nous proposons un patron formel permettant de transformer des algorithmes “avec détection de terminaison locale” en des algorithmes“avec détection de terminaison globale”. Ensuite, nous explicitons les preuves de correction d’un algorithme d’énumération. Nous proposons un développement formel qui servirait de point de départ aux calculs qui nécessitent l’hypothèse d’identification unique des processus. Enfin, nous étudions le problème du snapshot et du calcul d’état global. Nous proposons une solution basée sur une composition d’algorithmes existants. / In this work, we propose formal approaches for modeling andproving distributed algorithms. Such computations are designed to run oninterconnected autonomous computing entities for achieving a common task :each entity executes asynchronously the same code and interacts locally withits immediate neighbors. Correctness of distributed algorithms is a difficulttask and requires advancing methods and tools. In this thesis, we focus onsome basic problems of distributed computing, and we propose Event-B solutionsbased on the ”correct-by-construction” approach. We consider reliablesystems. We also assume that the network is anonymous and processes communicatewith asynchronous messages. In some cases, we refer to local computationsmodel to provide an abstraction of the distributed computations.We propose a formal framework enhancing the termination detection propertyof distributed algorithms. By relying on refinement and composition,we show that an algorithm specified with “local termination detection”, canbe reused in order to compute the same algorithm with “global terminationdetection”. We then focus on the enumeration problem : we start with anabstract initial specification of the problem, and we enrich it gradually bya progressive and incremental refinement. The computed result constitutesbasic initial steps of others distributed algorithms which assume that processeshave unique identifiers. We therefore focus on snapshot problems, andwe propose to investigate how existing algorithms can be composed, withrefinement, in order to compute a global state in an anonymous network.

Studies that approach the initialization mostly in the adult population have aimed to understand the limitations in postural disorders, aging and what little is in the child population also has a focus on disease and how this process occurs not because of the development of walking independent. This study aimed to describe how the gait initiation process occurs and how it changes as occurs the development of independent walking. We evaluated 29 subjects into three groups: G1 (15 months - 10 subjects), G2 (3 years - 9 subjects) and GA (Adult - 10 subjects). The variables were analyzed: amplitude of oscillation of the center of force toward the average side (COFML) and anterior posterior (COFAP) and average speed and VELAP VELML. The nonparametric Kruskal Wallis test was used to detect differences between groups; the significance level was p ≤ 0.05%. Results of gait initiation: COFAP (cm) there was no statistically significant differences between groups. However, both groups showed significant differences in the COFML behavior (7.79cm = G1, G3 = 7.46cm, GA = 3.25cm, p = 0.01). Furthermore the variable VELAP (cm / s), showed no statistically significant difference between groups, as well as the variable VLML. Results of gait termination: variables results COFAP (G1 = 11.15 cm, G3 = GA = 8.69 cm and 5.17 cm) and COFML (G1 = 7.83 cm, G3 = 8 cm and 4.86 cm = GA) showed no statistically significant differences when purchased between the three groups proposed both as a platform to platform 2. VELAP (G1 = 4.13 cm / s, G3 = 3.16 cm / GA = 3.26 cm / s) and VELML (G1 = 9.74 cm / s, G3 = 5.72 cm / s and GA = 2, 49 cm / s) were not statistically different during the completion of the gait termination, the results indicated the importance that the strength center behavior and the ability to deal with the gravitational field during the gait initiation and how this process changes with the experience of walking independently. / A inicialização de marcha é definida como transição da postura em pé ao primeiro passo a marcha cíclica, e envolve um programa motor mediado por ajustes preparatórios necessários para propulsionar o corpo para frente (MELOUIN ET AL,2000). Os estudos que abordam a inicialização em sua maioria em população adulta têm como objetivo compreender as limitações posturais em patologias e no envelhecimento e o pouco que se encontra em população infantil também tem o foco em patologias e não como este processo ocorre em função do desenvolvimento do andar independente. Este estudo teve por objetivo descrever como ocorre o processo de inicialização da marcha e como este muda à medida que ocorre o desenvolvimento do andar independente. Foram avaliados 29 sujeitos em três grupos G1 ( 15 meses 10 sujeitos), G2 ( 3 anos 9 sujeitos) e GA (adulto 10 sujeitos). As variáveis analisadas foram: amplitude de oscilação do centro de força na direção médio lateral (COFML) e antero posterior (COFAP) e velocidade média VELAP e VELML. O teste não paramétrico de Kruskal Wallis foi utilizado para detectar diferenças entre os grupos, o nível de significância foi de p ≤ 0,05%. Resultados Inicialização da marcha: COFAP (cm) não houve diferenças estatisticamente significativas entre os grupos. Porém, ambos os grupos apresentaram diferenças significativas para o comportamento da COFML (G1 = 7.79cm, G3 = 7.46cm, GA= 3.25cm e p= 0.01). Por outro lado a variável VELAP (cm/s), não apresentou diferença estatisticamente significativa entre os grupos,assim como a variável VLML. Resultados Finalização da marcha os resultados das variáveis COFAP (G1 = 11,15cm, G3 = 8,69 cm e GA = 5,17 cm) e COFML (G1 = 7,83cm , G3 = 8cm e GA = 4,86 cm) não apresentaram diferenças estatisticamente significativas quando compradas entre os três grupos propostos tanto para a plataforma 1 quanto para a plataforma 2. VELAP (G1 = 4,13cm/s, G3 = 3,16cm/s e GA = 3,26cm/s) e VELML(G1 = 9,74 cm/s, G3 = 5,72 cm/se e GA = 2,49 cm/s), não foram estatisticamente diferentes durante a finalização do marcha Como conclusão, os resultados indicaram importância que o comportamento do centro de força e a capacidade de lidar com o campo gravitacional durante a inicialização da marcha e como este processo muda de acordo com a experiência do andar independente.

This descriptive study has the Banco do Estado de Santa Catarina (BESC), Imprensa Oficial de Santa Catarina (IOESC) and Companhia de Distritos Indústriais de Santa Catarina (CODISC) to perform the analysis. These public organizations were terminated in the past 25 years, already inside a context of democracy reestablished nationally, press freedom and political affiliation. The subjects of this qualitative research are decision makers that were directly or indirectly linked to one of these organizations. It was found that the Multiple Stream Model can be seen as an explanation of termination in public organizations. From the analysis of the termination of the public organizations selected for this paper, it was verified the presence of the policy stream, problems stream and political stream that at a given moment in time, at the opening of a window of opportunity, had their paths crossed by the activity of a policy entrepreneur. / Esta dissertação tem como objetivo analisar a extinção de organizações públicas a partir do Modelo de Fluxos Múltiplos proposto por John Kingdon. Esse estudo descritivo tem como objeto de análise o Banco do Estado de Santa Catarina (BESC), a Imprensa Oficial de Santa Catarina (IOESC) e a Companhia de Distritos Indústriais de Santa Catarina (CODISC), organizações públicas extintas nos últimos 25 anos, já dentro de um contexto de democracia restabelecida nacionalmente, liberdade de imprensa e de filiação partidária. Os sujeitos dessa pesquisa qualitativa são tomadores de decisão que estavam direta ou indiretamente ligados a uma dessas organizações. Verificou-se que o Modelo de Fluxos Múltiplos pode ser visto como explicativo de fenômenos de extinção de organizações públicas. A partir da análise da extinção das organizações públicas selecionadas para este estudo, identificou-se a presença do Fluxo de política, do Fluxo de problema e do Fluxo de política ou solução que em determinado momento do tempo, por ocasião da abertura de uma janela de oportunidade, tiveram suas trajetórias cruzadas pela atividade de um empreendedor político.

Samhället står inför utmaningar gällande den ökade mängden sjukskrivningar till följd av högre arbetsbelastning och nedskärningar inom olika yrkesområden. Detta innebär i sin tur prövningar för den psykosociala arbetsmiljön. Denna studie har för avsikt att undersöka före detta enhetschefers psykosociala arbetsmiljö och dess eventuella samband till egen uppsägning. En kvalitativ ansats med målinriktat samt snöbollsurval ligger till grund för undersökningen. Sex intervjuer med före detta enhetschefer i en kommun har genomförts och en bearbetning av det empiriska materialet har skett genom en tematisk analys med hjälp av valda teorier såsom IMGD-modellen samt krav-, kontroll och stödmodellen. Resultatet visar att chefstjänsten har förändrats och att det finns bristande möjligheter att påverka uppdraget. I studien dras slutsatsen att konsekvenser av organisatoriska beslut gett upphov till brister i den sociala och organisatoriska arbetsmiljön vilket i sin tur resulterade i enhetschefernas uppsägning. / The society is facing major challenges regarding sickness absence due to psychosocial work-related causes and increased workload as a result of austerity measures in different professions. This study intends to investigate the psychosocial work environment of the former unit managers and possible links with their own termination. The survey is based on a qualitative approach with a targeted selection. In addition, a snowball surgeon has been used to make contact with significant persons for the purpose of the study. Six individual interviews with former unit managers in a municipality have been carried out and a processing of the empirical material has been done through a thematic analysis using selected theories like the IMGD model as well "high demand - low control model". The results show that unit manager's duties has changed and that the ability to influence the assignment was inadequate. The study indicates that there is a connection between the psychosocial work environment and the unit manager's own termination.
