Oxidation of silicon: further tests for the interfacial silicon emission model

The classical description of Si oxidation given by Deal and Grove has well-known limitations for thin oxides (below 200 Ã). Among the large number of alternative models published so far, the interfacial emission model has shown the greatest ability to fit the experimental oxidation curves. It relies on the assumption that during oxidation Si interstitials are emitted to the oxide to release strain and that the accumulation of these interstitials near the interface reduces the reaction rate there. The resulting set of differential equations makes it possible to model diverse oxidation experiments. In this paper, we have compared its predictions with two sets of experiments: (1) the pressure dependence for subatmospheric oxygen pressure and (2) the enhancement of the oxidation rate after annealing in inert atmosphere. The result is not satisfactory and raises serious doubts about the model’s correctness

A proposal for the diagnosis of uncertain dynamic systems based on interval models

The performance of a model-based diagnosis system could be affected by several uncertainty sources, such as,model errors,uncertainty in measurements, and disturbances. This uncertainty can be handled by mean of interval models.The aim of this thesis is to propose a methodology for fault detection, isolation and identification based on interval models. The methodology includes some algorithms to obtain in an automatic way the symbolic expression of the residual generators enhancing the structural isolability of the faults, in order to design the fault detection tests. These algorithms are based on the structural model of the system. The stages of fault detection, isolation, and identification are stated as constraint satisfaction problems in continuous domains and solved by means of interval based consistency techniques. The qualitative fault isolation is enhanced by a reasoning in which the signs of the symptoms are derived from analytical redundancy relations or bond graph models of the system. An initial and empirical analysis regarding the differences between interval-based and statistical-based techniques is presented in this thesis. The performance and efficiency of the contributions are illustrated through several application examples, covering different levels of complexity.

Customer satisfaction in the banking industry: a comparative study of Ghana and Spain

La satisfacció és una preocupació crucial pels clients i per les organitzacions, incloent els bancs. L'estudi examina la satisfacció global dels clients dels bancs a Ghana i Espanya. Així s'analitzen aspectes com la relació entre satisfacció global i les dimensions de qualitat dels serveis bancari, així com les pròpies dimensions principals de la qualitat d'aquests serveis. Finalment, les percepcions sobre aquestes dimensions son comparades entre els bancs de Ghana i Espanya. S'han analitzat els clients de 819 bancs de Ghana i Espanya, els resultats van mostrar que els clients espanyols estaven més descontents respecte les dimensions tangibles i empatia metre que els clients de Ghana puntuaven pitjar la dimensió conveniència. En general, els clients de Ghana estaven força més descontents amb els serveis bancaris que els d'Espanya. La fiabilitat, l'empatia i la conveniència son els predictors de satisfacció global en Ghana, mentres que la fiabilitat és la única dimensió que explica la satisfacció global a Espanya.

Aplicação do european customer satisfaction índex (ecsi) ao sector das águas

A Satisfação do cliente e a sua avaliação fazem parte integrante das preocupações dos gestores, sendo cada vez mais comum realizarem-se inquéritos juntos dos consumidores de modo a aferir a sua Satisfação. O Índice Nacional de Satisfação do Cliente (ECSIPortugal) é um sistema de medida da qualidade dos produtos e serviços disponíveis no mercado nacional, por via da Satisfação do cliente. A Satisfação dos clientes pode ser medida utilizando duas abordagens distintas, a tradicional e a estrutural. A metodologia utilizada no ECSI-Portugal segue a abordagem estrutural, baseada em modelos de equações simultâneas e variáveis latentes (SEM). A metodologia adotada neste projeto integra as seguintes etapas: – Realização de um inquérito junto dos clientes de cada entidade estudada; – Especificação e estimação de um modelo de Satisfação do cliente adequado a essas entidades; – Agregação dos resultados obtidos ao nível do setor e produção de informação sobre o conjunto da economia portuguesa. Pretende-se aplicar estes índices ao setor das águas de modo a que as entidades gestoras obtenham, entre outros benefícios, informação de gestão para atuarem em prol dos seus clientes, permitindo simultaneamente a criação de uma plataforma de validação dos resultados obtidos através de indicadores de desempenho.
