MEMS Comb Drive Gap Reduction Beyond Minimum Feature Size: A Computational Study

N. Osonwanne, and J.V. Clark
Purdue University, West Lafayette, IN, USA

In this paper we present a method to reduce the comb drive gap in micro electro mechanical systems (MEMS) beyond the minimum fabrication feature size. The benefit of reducing the gap space between comb drive fingers is to increase its sensitivity to changes in capacitance due to ... En savoir plus

Modeling of the Bread Baking Process Using Moving Boundary and Arbitrary-Lagrangian-Eulerian (ALE) Approaches

C. Anandharamakrishnan, N. Chhanwal, P. Karthik, D. Indrani, and K.S.M.S. Raghavarao
Central Food Technological Research Institute, Mysore, Karnataka, India

Bread baking is a complex process where various physiochemical and biological transformations take place simultaneously. A two dimensional model was developed for the bread baking process taking into account of volume expansion, heat and mass transfer processes. Phase change and ... En savoir plus

Design of High Performance Condenser Microphone Using Porous Silicon

S. Suganthi[1], M. Anandraj[2], and L. Sujatha[1]
[1]Department of Electronics & Communication Engineering, Rajalakshmi Engineering College, Chennai, India
[2]Department of Physics, Rajalakshmi Engineering College, Chennai, India

Porous Silicon (PS) can easily be formed by electrochemical etching of silicon in HF based electrolytes at room temperature. Since, PS is compatible with silicon IC technology; it finds lot of applications in the fabrication of MEMS devices. In the current study, we discuss the design of ... En savoir plus

Thermal Analysis of Joule Heated Ceramic Melter

P. Goyal, V. Verma, R.K. Singh, and K.K. Vaze
Bhabha Atomic Research Centre, Mumbai, Maharashtra, India

High level radioactive waste (HLW) generated by nuclear fuel cycle is immobilized using glass melters. In Glass melters such as Joule Heated Ceramic Melter (JHCM) electrodes immersed in the glass generates heat by the joule heating due to electric current passing between electrodes ... En savoir plus

Simulation Of Soil Remediation Polluted By Hydrocarbons Using A Non-Thermal Atmospheric Plasma

J. Rojo, S. Ognier, and S. Cavadias
Laboratoire de Génie des Procédés Plasmas et Traitements de Surfaces, University Pierre et Marie Curie, Paris, France

A lot of techniques are developed to treat soils polluted by hydrocarbons pollutants: incineration, thermal treatment, extraction, chemical oxidation, bioremediation… Some of these techniques are very energy consuming (incineration, thermal treatment…) and often need a subsequent ...

Dynamic Model for Catenary Mooring: Experimental Validation of the Wave Induced Load

L. Martinelli[1], A. Spiandorello[2], P. Ruol[3], and A. Lamberti[1]
[1]DICAM, Università di Bologna, Italy
[2]Civil Engineer, Italy
[3]IMAGE, Università di Padova, Italy

This paper will present a numerical model based on COMSOL Multiphysics suited to simulate the dynamic response of a catenary mooring (or a submarine cable). In general, mooring lines are subject to a direct wave load (e.g. drag, inertia) in addition to the movement of the vessel to ... En savoir plus
