The boundary element method (BEM) is one of numerical methods for the boundary-value problem of partial differential equations and has been so far used in the fields of plasma and fusion science. For example, the BEM has been adopted for solving the Grad-Shafranov (G-S) equation which describes the magnetohydrodynamics equilibrium in an axisymmetric plasma [1]. On the other hand, Mukherjee et a...

O artigo que se apresenta tem por objeto central ser um atravessamento entre as noções de bem comum e individual. Assim, pretendeu-se desenvolver a explicação do percurso histórico-filosófico, onde deu passagem interposição concepções éticas individual; no diz respeito, mesmo modo, à antiguidade grega o mundo helênico. Por conseguinte, presente escrito tratar-se-á da apresentação panorama geral...

têm sido estudadas visando a obtenção de condições ideais de cultivo, bem como a seleção de linhagens mais adequadas à maricultura (Patwary & van der Meer 1982, van der Meer & Patwary 1983, Zhang & van der Meer 1987). O manejo bem sucedido de uma espécie está condicionado ao conhecimento de sua biologia. Portanto, o histórico de vida tem sido objeto de estudo em muitas espécies de Gracilaria, c...

wind power has been widely considered and utilized in recent years as one of the most promising renewable energy sources. in the current research study, aerodynamic analysis of the upwind three-bladed horizontal axis turbine is carried out using blade element momentum theory (bem), and a genetic algorithm (ga) is applied as an optimization method. output power generation is considered as an obj...

Alternative representations of boundary integral operators corresponding to elliptic boundary value problems are developed as a starting point for numerical approximations as, e.g., Galerkin boundary elements including numerical quadrature and panel-clustering. These representations have the advantage that the integrands of the integral operators have a reduced singular behaviour allowing to ch...
