Convergence of the Godunov scheme for a simplified one-dimensional hydrodynamic model for semiconductor devices

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

The Quantum Hydrodynamic Model for Semiconductor Devices

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Convergence of the Godunov scheme for straight line systems

Here A(u) is a map from a domain U ⊂ Rn into Rn×n, and (x, t) ∈ R×R+. We assume strict hyperbolicity, i. e. the the matrix A(u) has n real and strictly different eigenvalues for each u ∈ U . In the conservative case when A(u) = Df(u) for some map f : U → Rn, Glimm [12] proved global existence of weak entropy solutions of (1) when the data has small total variation and each characteristic field ...
