In this work, we develop a reduced-basis approach for the e cient computation of parametrized expected values, for a large number of parameter values, using the control variate method to reduce the variance. Two algorithms are proposed to compute online, through a cheap reduced-basis approximation, the control variates for the computation of a large number of expectations of a functional of a p...

We present a method to solve initial and boundary value problems using arti ial neural networks. A trial solution of the di erential equation is written as a sum of two parts. The rst part satis es the initial/boundary onditions and ontains no adjustable parameters. The se ond part is onstru ted so as not to a e t the initial/boundary onditions. This part involves a feedforward neural network, ...

|This paper presents the investigations in the electric performance of di¬erential signalling transmission lines used for high speed integrated circuits (IC’s) and boards by using the parallelized ­ nite-di¬erence time-domain (FDTD) method. The FDTD method is ­ rstly parallelized with single-program multipledata (SPMD) architecture using the MPI protocol and experimentally validated. The key el...

In this paper, we are concerned with a class of nonlinear implicit fractional di?erential equation adiscrete delay. By means the contraction mapping principle, prove existence unique solution.Then, investigate continuous dependence solution upon initial delay data and Ulamstability.
