Integrated Hierarchical Design of Microelectrofluidic Systems using SystemC

Zhang T., Chakrabarty K., Fair R.B., Cadence Design Systems, Inc., US

This paper describes the role of SystemC in developing an integrated modeling and simulatio environment for microelectrofluidic systems (MEFS). Based on the unique modeling and simulation needs for MEFS, we examine suitability of several existing [...]

Large-Deflection Beam Model for Schematic-Based Behavioral Simulation in NODAS

Jing Q., Mukherjee T., Fedder G.K., Carnegie Mellon University, US

MEMS design in NODAS is based on a geometrically intuitive schematic representation of MEMS using a small set of atomic elements (anchors, beams, plates and electrostatic gaps), each of which is associated with a geometrically [...]

Integrated Modeling of Optical MEMS Subsystems

Stoll R., Plowman T., Winick D., Morris A., Coventor, US

This paper presents top-down holistic design and verification of a MEMS-based 3-D optical switching subsystem utilizing an integrated CAD environment. The subsystem design takes place in a nodal simulation environment that includes models for fibers, [...]

Improving Trajectory Piecewise-Linear Approach to Nonlinear Model Order Reduction for Microm䁡chined Devices Using an Aggregated Projection Basis

Rewienski M., White J.K., Massachusetts Institute of Technology, US

In this paper we present an improved algorithm for nonlinear model order reduction (MOR) based on the trajectory piecewise-linear method proposed in [6] which, as shown before, provides an e ective and eÆcient strategy for [...]

Physically-Based Damping Model for Highly Perforated and Largely Deflected Torsional Actuators

Sattler R., Schrag G., Wachutka G., Münich University of Technology, DE

We propose a mixed level simulation scheme for squeeze film damping (SQFD) effects in microdevices, which enables the inclusion of damping effects in system level models of entire microsystems in a natural, physical-based, and flexible [...]

Modeling, Simulation and Design of Piezoelectric Micro-Hydraulic Transducer Devices

Yaglioglu O., Su Y.H., Roberts D.C., Carretero J., Hagood N.W., Massachusetts Institute of Technology, US

This paper reports on modeling, simulation and design considerations for piezoelectric Micro-Hydraulic Transducer (MHT) systems, focusing on power generation applications. Since these devices are complex fluid and structural systems, comprehensive simulation tools are needed for [...]

What to do with Statistical Mechanics when the Figure of Merit Cannot be Calculated: Library Design for High-Throughput Materials Development

Deem M.W., University of California, Los Angeles, US

By analogy with Monte Carlo algorithms, we discuss new strategies for design and redesign of libraries in high-throughput experimentation, or combinatorial chemistry. Several Monte Carlo methods are examined, including Metropolis, several types of biased schemes, [...]

The Inverse Band Structure Approach: Given the desired electronic property, find the atomic configuration

Zunger A., National Renewable Energy Laboratory, US

Modern crystal-growth techniques, such as molecular beam epitaxy or metal-organic chemical-vapour deposition, are capable of producing prescribed crystal structures, sometimes even in defiance of equilibrium, bulk thermodynamics. These techniques open up the possibility of exploring [...]

The Number of Human Genes and Proteins

Davison D., Bristol-Myers Squibb, Pharmaceutical Research Institute, US

The definitive prototype for nanotechnology is the cell. Its many machines and exquisitely controlled internal and external movements are a reference for all researchers working in the field. The complete instructions for every molecular machine [...]
