Low-order nonconforming Galerkin methods will be analyzed for second-order elliptic equations subjected to Robin, Dirichlet, or Neumann boundary conditions. Both simplicial and rectangular elements will be considered in two and three dimensions. The simplicial elements will be based on P1, as for conforming elements; however, it is necessary to introduce new elements in the rectangular case. Op...

in this paper, we use petrov-galerkin elements such as continuous and discontinuous lagrange-type k-0 elements and hermite-type 3-1 elements to find an approximate solution for linear fredholm integro-differential equations on $[0,1]$. also we show the efficiency of this method by some numerical examples

We derive inverse trace inequalities for hp-finite elements. Utilizing orthogonal polynomials, we show how to derive explicit expressions for the constants when considering triangular and tetrahedral elements. We also discuss how to generalize this technique to the general d-simplex. 2003 Elsevier Science B.V. All rights reserved.

Cet article porte sur le rapport entre l’écriture dystopique de Rachid Boudjedra et la théorie postcoloniale dans son roman L’Escargot entêté. Cette œuvre fait partie littérature algérienne se trouve, par conséquent, être l’emblème d’une esthétique hybride. L’hybridité dont use l’auteur, qui n’est autre qu’un concept utopique postcoloniale, finit briser texte, générant là une écriture dystopiqu...

friction welding is widely used in various industries. in friction welding, heat is generated by conversion of mechanical energy into thermal energy at the interface the work pieces during pin rotation under pressure. a three-dimensional thermo mechanical simulation of friction stir welding (fsw) processes is carried out for aluminium alloys of 6061and 7050 where the simulation results are comp...
