Resistance welding of crossed wires, e.g. used in the electronics industry or fabrication wire meshes, is analyzed by both experiments and numerical modeling using an electro-thermo-mechanical finite element formulation. Welding machine characteristics are discussed necessary requirements to type concluded. Cross-wire stainless steel, structural steel aluminum presented, differences process fla...

In order to understand the dynamics of Z-pinch irnposions of thin wires in pulsepower accelerators, it is necessaryto understandthe physicalprocessby which the initially solid wires are coverted into plasma by rising current. For this purpose, we model wire explosions using TRAC II, a tw~demensional MHD code, in three distinct cases: pure tungsten, impure tungsten, and gold-plated tungsten. We ...

| This article describes a topological routing path search algorithm embedded in our autorouter for printed circuit boards. The algorithm searches for a topological path that is guaranteed to be transformable into a physical wire satisfying design rules. We propose a method for incrementally verifying design rules during topological path search in a graph based on constrained Delaunay triangula...

We present a self-consistent method for the evaluation of the electronic current flowing through a multi-terminal molecular wire. The method is based on Büttiker-Landauer theory which relates the current to one-electron scattering probabilities. The scattering problem is solved using a tight-binding form for Schrödinger’s equation that incorporates a self-consistent evaluation of the electro-st...
