Spatio-temporal Tumor Model for Analysis and Mechanism of action of Intracellular Drug Accumulation

Mishra S., Katiyar V.K., Arora V., Haridwar, IN

We have developed a one-dimensional tumor simulator to describe the biodistribution of chemotherapeutic drugs to a tumoral lesion and the tumor cell’s response to therapy. A three-compartment model is used for drug dynamics within the [...]

Characterization and Optimization Design of the Polymer-based Capacitive Micro-arrayed Ultrasonic Transducer

Chiou D.Y., Chen M.Y., Chang M.W., Deng T.M., RFID Technology Center/Industrial Technology Research Institute (RTC/ITRI), TW

The polymer-based capacitive micro-arrayed ultrasonic transducer (P-CMUT) have been shown to be a more attractive alternative to conventional CMUT in terms of “flexibility” that can be applied in many areas, ranging from consumer electronics to [...]

Optimization of Piezoelectric Transformers Using Elite Genetic Algorithm

Kang C-Y., Lee C-K, Yang Y-J, National Taiwan University, TW

In this work, we present the optimization work for piezoelectric transformers (PT) by using the elite Genetic Algorithm (GA). The Finite-element solver, NTUPZE, is used to calculate the behaviors of piezoelectric transformers. The design parameters [...]

Correlation of Experimental and Numerical Results on Electrostatically Actuated Micro-Beams

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

The aim of this paper is to validate numerical simulations of electromechanical coupling in micro-structures using some experimental results. The micro-structures studied here consist in a micro-bridge and two cantilever beams. Multi-physics simulations of micro-electro-mechanical [...]

Parametric Simulation of MEMS Based on Automatic Differentiation of Finite Element Codes

Kolchuzhin V.A., Mehner J.E., Gessner T., Doetzel W., Chemnitz University of Technology, DE

The key idea of the presented approach, which account for parameter variations in a single finite element run, is to compute not only the governing system matrices of the FE problem but also their partial [...]

Development of a 3-D Finite-element Solver for Piezoelectric Transformer Analysis

Chen Y-M, Lee C-K, Yang Y-J, National Taiwan University, TW

Piezoelectric transformers step up or step down input voltages by electrical/mechanical/electrical conversion. Piezoelectric transformers have been proved to be promising alternatives for magnetic transformers. Furthermore, since the fabrication technology of thin-film piezoelectric materials becomes mature, [...]

Investigation of dsDNA Stretching Meso-mechanics using Finite Element Method

Yuan C.A., Chiang K.N., National Tsing Hua University, TW

A novel finite element model with equivalent meso-mechanics theory is proposed herein to simulate the dynamic structural transitions of the double strand DNA (dsDNA) under external loading. Moreover, the meso-mechanics of dsDNA molecules is then [...]
