Abstract:

Ce manuscrit présente les travaux de recherche qui concernent l'analyse et la synthèse de structures rayonnantes multidimensionnelles en utilisant une approche qui combine méthode des moments et la transformée de Fourier spatiale. La distribution source (courant électrique) et le diagramme de rayonnement sont liées par la transformée de Fourier spatiale - la théorie de la Relation de Fourier (FR). La distribution des courants est déterminée en utilisant une méthode d'analyse en électromagnétisme (EM), à savoir la Méthode des Moments (MoM). Des travaux antérieurs utilisant la théorie FR ont été

Abstract:

Knowledge of unsaturated zone hydraulic properties is critical for many environmental and engineering applications. Various stochastic methods have been developed during the past two decades to estimate the effective unsaturated hydraulic properties. Independent of these stochastic methods, we develop in this paper a practical approach to estimate the three-dimensional (3 -D) effective unsaturated hydraulic conductivity tensor using spatial moments of 3-D snapshots of a moisture plume under transient flow conditions. approach hydraulic hydraulic Application of the new to a field site

Abstract:

A regionalização hidrológica é uma técnica que permite transferir informação entre bacias hidrográficas semelhantes, a fim de calcular em sítios que não dispõem de dados, as variáveis hidrológicas de interesse; assim, a mesma caracteriza-se por ser uma ferramenta útil na obtenção de outorga de direitos de uso de recursos hídricos, instrumento previsto na Lei 9433/97. Devido à desatualização do modelo atual de regionalização hidrológica do Estado de São Paulo, proposto na década de 80, este estudo tem como objetivo geral avaliar se o mesmo está adequado ao uso, de acordo com a atualização de se

Abstract:

This paper develops a unified framework for fixed and random effects estimation of higher-order spatial autoregressive panel data models with spatial autoregressive disturbances and heteroskedasticity of unknown form in the idiosyncratic error component. We derive the moment conditions and optimal weighting matrix without distributional assumptions for a generalized moments (GM) estimation procedure of the spatial autoregressive parameters of the disturbance process and define both a random effects and a fixed effects spatial generalized two-stage least squares estimator for the regression pa

Abstract:

Le tourisme contribue à hauteur de plus de 15 % dans le PIB national tunisien (WTTC, 2017 : p 1). Ce secteur, depuis sa création dans le milieu des années soixante-dix, a toujours été un des plus importants moteurs de l’économie du pays. Depuis le début des années deux mille, le modèle, basé sur la commercialisation des produits classiques [4 S : sea, sun, sand (plage), sand (désert)] à une clientèle majoritairement occidentale, a atteint la saturation. Au cours de cette période, la chute a commencé à se sentir jusqu’à atteindre une situation critique aggravée par les événements terroristes qu

This paper develops an estimator for higher-order spatial autoregressive panel data error component models with spatial autoregressive disturbances, SARAR(R,S). We derive the moment conditions and optimal weighting matrix without distributional assumptions for a generalized moments (GM) estimation procedure of the spatial autoregressive parameters of the disturbance process and define a generalized two-stage least squares estimator for the regression parameters of the model. We prove consistency of the proposed estimators, derive their joint asymptotic distribution, and provide Monte Carlo evi

Abstract:

Ce manuscrit est consacré à l'amélioration des deux méthodes numériques : MMDF et Méthode des Moments avec la technique de la RSA. Dans un premier temps, on présente les outils théoriques sur l'étude du problème de la diffraction par des réseaux lamellaires, éclairée sous incidence classique et les outils de simulation pour résoudre les équations de Maxwell. On choisit comme fonctions de base et de test, les fonctions triangles. On introduit par la suite, la technique de la RSA afin d'améliorer la vitesse de convergence de calcul. Les résultats obtenus sont comparés à ceux de la méthode MMFE e
