Finite-Element Modeling of 3C-SiC Membranes

DeAnna R.G., Mitchell J., Zorman C.A., Mehregany M., U.S. Army Research Laboratory, US

Finite-element modeling (FEM) of 3C-SiC thin-film membranes on Si substrates was used to determine the residual stress and center deflection with applied pressure. The anisotropic, three-dimensional model includes the entire 3C-SiC membrane and Si substrate [...]

Modelling of Processes of Photoacoustic Diagnostic with Piezoelectric Detection

Vertsanova O., Perlov I., Tsyganok B., National Technical University of Ukraine, UA

Authors developed the one-dimensional mathematical model of piezoelectric detection of photoacoustic effect in thermally thick and optically opaque sample with subsurface defect. The model is developed in view of the assumptions of ideally rigid connection [...]

Atomic Force Microscopic Visualization of Identical Site on Cell Surface with Different Probes

Ohta Y., Kobayashi T., Okamoto H., Okuda T., Toyo University, JP

For these several years Atomic Force Microscopy (AFM) has been widely used for visualization of biological samples with high resolution on nanometer scale. Whereas any biological information regarding specific reactions, such as immunological function, cannot [...]

Auto-Regressive Time Series Modeling of Stochastic Surfaces

Rao B.N.P., Murti V.S.R., Osmania University, IN

Roughness profiles of EDM surfaces were obtained from a perthometer and digitized through AUTO CAD. Fortran program was developed for fitting ARMA (n, n-1) models. A significant observation was that for the sinking electrode type. [...]

Modeling of High-speed Diamond Microswitch

Schmid P., Adamschik M., Ertl S., Kohn E., University of Ulm, DE

CVD grown diamond is a new attractive MEMS material and has been used here to realize a microswitch with extreme properties. Still at present the technological development requires a fast turnaround of the design based [...]

Hardware Realization of Biological Mechanisms Using VHDL and FPGAs

Botros N., Akaaboune M., Alghazo J., Alhreish M., Southern Illinois University, US

In this paper we present a hardware realization of a simplified blood-pressure regulation mechanism. The mechanism has been proposed and then modeled by using Hardware Description Language (VHDL). After verifying the simulation results, Computer Aided [...]

Compact Models for Smart Pixels with Smart Illumination

Subramanian Y., Azadeh M., Darling R.B., University of Washington, US

Smart Pixels with Smart Illumination (SPSI) is a recently developed technology that enables the monolithic integration of two functionalities-optical illumination and detection- into arrays of optoelectronic ‘pixels’ in a compact and robust manner. To facilitate [...]

A Synthesizable Low Power VHDL Model of the Exact Solution of Three Dimensional Hyperbolic Positioning System

Bucher R., Misra D., New Jersey Center for Wireless and Telecommunication, US

This paper presents a synthesizable low power VHDL model of a three-dimensional hyperbolic positioning system algorithm. The algorithm derives the equations needed to obtain an exact solution for the three dimensional location of a mobile [...]

A FEM Based Network Approach for the Simulation of Miniaturized Electromagnetic Devices

Gollee R., Gerlach G., Dresden University of Technology, DE

The paper proposes a new computational approach for analyzing miniaturized electromagnetic devices. This approach is based on a general structure of an equivalent network for the coupled electromagnetic problem. It enables automated derivation of the [...]

Electromechanical Analysis of Micromechanical SOI-Fabricated RF Resonators

Lamminmäki T., Ruokonen K., Tittonen I., Mattila T., Jaakkola O., Oja A., Seppä H., Seppälä P., Seppälä P., Kiihamäki J., Helsinki University of Technology, FI

In this paper, finite element method (FEM) simulations are used to model mechanical properties of MEMS resonators. Using a static displacement analysis the effective spring constant and mass are calculated. Non-linearity of the mechanical restoring [...]
