A Computational Model with Experimental Validation for DNA Flow in Microchannels

Nonaka A., Gulati S., Trebotich D., Miller G.H., Muller S., Liepmann D., UC Davis / Lawrence Livermore National Laboratory, US

We compare a computational model to experimental data for DNA-laden flow in microchannels. The purpose of this work in progress is to validate a new numerical algorithm for viscoelastic flow of an Oldroyd-B fluid. Significant [...]

Model for Compression of Fullerenes and Carbon Nanotubes

Jindal P., Jindal V.K., Jindal P., Jindal V.K., Panjab University, IN

This abstracts highlights methodology to use fullerene and carbon nanotubes to utilize their empty space for high pressure absorbing capabilities.

Finite Element Modeling of Electro-Mechanical Coupling in Capacitive Micro-Systems

Rochus V., Rixen D.J., Golinval J.-C., University of Liege, BE

The aim of this paper is to deal with multi-physics simulation of micro-electro-mechanical systems (MEMS) based on an advanced numerical methodology. MEMS are very small devices in which electric as well as mechanical and fluid [...]

A Wavelet Method for the Density-Gradient Equation

Morris H., Limon A., San Jose State University, US

As MOSFET device lengths have shrunk to submicron level, so too has the oxide thickness steadily reduced. At around 4-5nm thicknesses quantum effects start to become noticeable as electrons are able to tunnel through the [...]

Electron Energy States of INAS/GAAS Quantum Ring Array

Filikhin I., Deyneka E., Melikian G., Vlahovic B., North Carolina Central University, US

Planar array of semiconductor quantum rings is studied under the energy dependent effective mass approximation. Rectangular shape InAs quantum rings (QR) are embedded into the GaAs substrate. The 3D confined energy problem is solved numerically [...]

3-Dimensional Diffusion-Reaction Model for DNA Hybridization on Microarrays

Pappaert K., Baron G.V., Desmet G., Free University of Brussels, BE

Molecular diffusion limits the hybridization rate in microarrays, leading to overnight waiting times. During the last couple of years a large number of methods were developed to overcome this diffusion-limitation and to enhance the speed [...]

Investigation of Local-Strain Effect of the Nano-Scale Triple Gate Si/SiGe and SiN/Si Stacking MOS Transistor

Chang C.H., Chou C.Y., Peng C.T., Han C-N, Chiang K.N., National Tsing Hua University, TW

The tensile strained Si, based on the misfit between Si and SiGe gives higher speed and higher drive current for the metal oxide silicon field effect transistors. Based on the strained Si technology, a tri-gate [...]

Parameter Preserving Model Order Reduction of a Flow Meter

Moosmann C., Rudnyi E.B., Greiner A., Korvink J.G., Hornung M., IMTEK, University of Freiburg, DE

Model order reduction is known to work reliably for MEMS simulations and can beused to speed up transient and harmonic computations tremendously. However, using standard model reduction techniques the generated reduced models are only able [...]

Modeling of Laser Assisted Direct Imprinting Process Based on Pulsed Laser Heating and Elastodynamic Theory

Lee Y-C, Chuang C-H, Wang D-B, Liu C-P, Hsiao F-B, National Cheng Kung University, TW

Laser Assisted Direct Imprinting (LADI) is an efficient and direct way for fabricating nanostructures. In short, a quartz mold with nano-features is first pressed against a sample. Upon radiating a short laser pulse on the [...]

High Accuracy Exponential Function Generator for Analog Signal Processing

Popa C., University Politehnica of Bucharest, RO

A new CMOS current-mode pseudo-exponential circuit based on the superior-order Taylor series expansion will be presented. The advantage of the circuit with respect to the previous reported similar ones is the smaller value of the [...]
