We have developed a twoand three-dimensional simulation tool for a coupled electro-thermal analysis of VLSI interconnect lines, which uses the finite element method to solve Laplace's equation and the heat conduction equation. Thereby, triangular and tetrahedral grid elements with linear and quadratic shape functions are used. Two preprocessors allow a layer-based input of the simulation geomet...

The aim of this paper is to present some recent developments and hints for future researches in control inspired of flatness-based ideas. We explain how explicit trajectory parameterization, a property that is central for flat systems, can be useful for the control of various oscillatory systems (linear, nonlinear, finite and/or infinite dimension) of physical and engineering interests. Such pa...

This paper illustrates a novel topology for the conditioning of electro-oculogram signals. The system is composed of a second order amplification chain and assures stability, speed and accuracy. The proposed configuration has been developed in order to make signal acquisition of biological signals such as electro-oculogram simpler and robust with low cost. The filters between the preamplificati...

The paper presents a methodology for simulating the static and dynamic performance of integrated circuits in the presence of electro-thermal interactions on the integrated circuit die. The technique is based on the coupling of a FEM program with a circuit simulator. In difference to other known simulator couplings the time step algorithm is used. Its implementation into simulation tools is desc...

Many of nonlinear systems in the field of engineering such as nano-resonator and atomic force microscope can be modeled based on Duffing equation. Analytical frequency response of this system helps us analyze different interesting nonlinear behaviors appearing in its response due to its rich dynamics. In this paper, the general form of Duffing equation with cubic nonlinearity as well as par...

We study the conditions for soliton-like wave propagation in the Photorefractive (PR) and electro-optic (i.e., Pockels) material, by using Nonlinear Schrodinger (NLS) equation. The complete NLS equation is solved analytically and numerically by transforming it into the phase space. Our results clearly show the existence of both the dark and bright solitary solutions for the PR medium. Interesti...
