Solutions of the Boltzmann Equation via a Discrete Velocity Monte Carlo Method

Category: Seminar

Professor Philip L. Varghese, University of Texas Austin. A discrete velocity scheme for solving the Boltzmann equation will be described and demonstrated by application to homogeneous and one-dimensional problems. Direct solution of the Boltzmann equation is computationally expensive because, …

Modeling of Dielectric Charging in RF MEMS

Category: Seminar

Professor Ashraf Alam, Purdue University. An insulator, by definition, carries no conduction current. Practical insulators (e.g. oxide) however seem to not know the definition and as voltages are ramped across them, charges injected from the electrodes accumulate within the oxide, and change …

Multiphysics and Multiscale Analysis of MEMS/NEMS

Category: Seminar

Professor Narayan R. Aluru, University of Illinois at Urbana-Champaign. Micro and nanoelectromechanical systems (MEMS and NEMS) are miniaturized sensors, actuators, devices and systems. Micromachined devices such as accelerometers, gyroscopes, pressure sensors, valves, pumps, single-chip …

Understanding and Improving Longevity In RF MEMS Capacitive Switches

Category: Seminar

Dr. Chuck Goldsmith, Ph.D., MEMtronics Corporation. Capacitive switching technology possesses many benefits over both conventional electronic switching devices and ohmic-contact MEMS switches at microwave and millimeter-wave frequencies. These benefits include a very high figure of merit, low …

NNSA PRISM Workshop: Verification and Validation (V&V): Quantifying Prediction Uncertainty and Demonstrating Simulation Credibility

Category: Seminar

Dr. François M. Hemez, Ph.D., Los Alamos National Laboratory. The goal of the workshop is to provide training in the areas of Verification and Validation (V&V) and Quantification of Prediction Uncertainty. Verification and Validation (V&V) refers to a broad range of activities that are carried …
