We present and analyze a parallel method for the solution of partial diierential equation models of the nervous system. These models mathematically are one-dimensional nonlinear parabolic equations deened on branching domains. Implicit methods for these equations leads to numerical solution of diagonally dominant almost tridiagonal linear systems at each time step. We rst review some exact meth...

The mechanisms of texture development were examined for BaTiO₃ and a (K,Na,Li)(Nb,Ta)O₃ solid solution made by the templated grain growth method, and compared with the mechanism in Bi0.5(Na,K)0.5TiO₃. The dominant mechanism was different in each material; grain boundary migration in BaTiO₃, solid state spreading in Bi0.5(Na,K)0.5TiO₃, and abnormal grain growth in the (K,Na,Li)(Nb,Ta)O₃ solid so...

RÉSUMÉ. Nous proposons un algorithme distribué, asynchrone, silencieux et autostabilisant calculant un ensemble k-dominant minimal d’un réseau identifié quelconque de n processus. La taille de l’ensemble k-dominant calculé est d’au plus ⌈ n k+1 ⌉ processus. À partir d’un transformateur présenté également dans cet article, nous obtenons une solution fonctionnant sous un ordonnanceur inéquitable ...

This paper considers some permutation flow shop scheduling problems with a learning effect on no-idle dominant machines. The objective is to minimize maximum completion time. This objective is considered under following dominant machines constraint: idm, ddm, idm–ddm and ddm–idm. We present a polynomial-time solution algorithm for each of the above cases. 2006 Elsevier Inc. All rights reserved.

We present new evidence in support of the Penrose's strong cosmic censorship conjecture in the class of Gowdy spacetimes with T 3 spatial topology. Solving Einstein's equations perturbatively to all orders we show that asymptotically close to the boundary of the maximal Cauchy development the dominant term in the expansion gives rise to curvature singularity for almost all initial data. The dom...

Accumulative roll bonding (ARB) was used to fabricate the Cu-Zn multilayer and Cu-Zn solid solution. A lamellar structure with the hardness of about 130 VHN was formed after eight ARB cycles. Following to the suitable heat treatment, a solid solution with a uniform microstructure and hardness of about 57 VHN was produced. The dominant wear mechanism in the ARB processed multilayer was found to ...
