A prop-03 de la tetanie de l'cnfant: presentation de quelques cas, reYue de la. litterature.  Parmi les diverses etiologies de la tetanie in­fantile, le rachitisme et la malabsorption sont les causes les plus frequentes en Iran.  La tetanie s'observe plus volontiers au debut du rachitisme et dans des stades avances. Un seul cas de tetanie fut obse:rve chez un enfant de trois mo:is, ancien pre...

Background Access to appropriate and affordable healthcare is needed to achieve better health outcomes in Africa. However, access to healthcare remains low, especially among the poor. In Zambia, poor access exists despite the policy by the government to remove user fees in all primary healthcare facilities in the public sector. The paper has two main objectives: (i) to examine the factors assoc...

Résumé. Nous décrivons un processus de fouille de données en bioinformatique. Il se traduit par la spécification de modèles de Markov cachés du second-ordre, leur apprentissage et leur utilisation pour permettre une segmentation de grandes séquences d’ADN en différentes classes qui traduisent chacune un état organisationnel et structural des motifs d’ADN locaux sous-jacents. Nous ne supposons a...

Parallel iterative methods are powerful tool for solving large system of linear equations (LEs). The existing parallel computing research results are focussed mainly on sparse system or others with particular structure. And most are based on parallel implementation of the classical relaxation methods such as Gauss-Seidel, SOR, and AOR methods carried efficiently on multiprcessor systems. In thi...

We consider the implicit time integration of the compressible Navier-Stokes equations. Each implicit step involves the solution of a costly non linear system. In this paper, we deene a preconditioner to solve each linear system more cheaply within the framework of matrix-free algorithm. The main idea is to reuse the Krylov subspace across the time steps. We demonstrate some properties of the pr...

MLF is a language that extends ML and System F and combines the benefits of both. We propose a dag representation of MLF types that superposes a term-dag, encoding the underlying term structure with sharing, and a tree encoding the binding structure. Compared to the original definition, this representation is more canonical as it factors out most of the notational details; it is also closely re...

‎in this paper‎, ‎an efficient algorithm for solving a system of linear‎ ‎equations based on the homotopy analysis method is presented‎. ‎the‎ ‎proposed method is compared with the classical jacobi iterative‎ ‎method‎, ‎and the convergence analysis is discussed‎. ‎finally‎, ‎two‎ ‎numerical examples are presented to show the effectiveness of the‎ ‎proposed method.‎
