This abstract addresses the effect of scaling in air gap MOSFETs and determination of functional relationship between scaling parameter and sensitivity, frequency response. The modelling of the MOSFET and its simulations has been carried out using COMSOL Multiphysics. An air Gap MOSFET in its simplest form can be imagined to be one obtained by replacing the dielectric in a MOSFET with air. The ...

The elbow joint in dogs constitutes a complex interaction of three bones, the humerus, radius and ulna. Medial coronoid disease (MCD) is a common cause of lameness in dogs, i.e. fracturing of the most prominent portion of the ulnar joint surface driven in flexion and in pivot against both the humerus and the radius. The cause remains unknown, but prior studies suggest joint incongruency as an ...

Application for Ultrasensitive Biosensing by Nanodevise

[1]Takatoki YAMAMOTO

Tokyo Institute of Technology, Yokohama, Kanagawa, Japan[1]

It is possible to obtain novel functions using nano-scaled structures and related physics that are impossible to be realized by conventional macro-scale technology. Thus, we are trying to understand the physics dominated by nanostructure and to develop the biosensing applications. Here, we exploit the interaction between materials and electrostatic field created by nanostructure, and introduce ...

This paper presents the results of modeling of a microreactor with three inputs geometry (or crow's-feet), in relation to distributions of velocities and concentrations. The objective of this work is the study of this kind of geometry with relation to fluid dynamics behavior, improving the knowledge of microfluidics and microreactors projects. These numerical responses allow conclusions about ...

2-Dimensional Incompressible and Compressible Mantle Convection - new

Changyeol Lee[1]
[1]Faculty of Earth and Environmental Sciences, Chonnam National University, Gwangju, Republic of Korea

COMSOL Multiphysics® software has been used in computational geodynamics for years. Because very high pressure in the mantle even significantly compressed the mantle up to ~40%, it is crucial to consider the mantle compressibility in computational geodynamics. COMSOL Multiphysics allows consideration of mantle compressibility using the CFD Module and I benchmarked COMSOL Multiphysics using ...

Iberian COMSOL Multiphysics Conference

The Organizing Committee of the Iberian COMSOL Multiphysics Conference 2014

Scraping Non-Newtonian Power-Law Paint

C. R. Meyer [1], J. R. Rice [1],
[1] Harvard University, Cambridge, MA, USA

A similarity solution to Taylor's paint scraper problem for the flow of a non-Newtonian power-law fluid is presented. A shooting method numerical solution agrees with the results found for Newtonian fluids and is able to capture both shear-thinning and shear-thickening fluids. Simulations created in COMSOL Multiphysics® software are also presented to corroborate the shooting method and display ...

Simulating Organogenesis in COMSOL: Towards Efficient 3D Simulations of Organogenesis

D. Barac [1], Z. Karimadini [1], R. Croce [1], D. Iber [1]
[1] Department of Biosystems Science and Engineering (D-BSSE), ETH Zurich, Basel, Switzerland

One of the major challenges in biology concerns the integration of data across length and time scales into a consistent framework: how do macroscopic properties and functionalities arise from the molecular regulatory networks ­ and how do they evolve? A deeper understanding of morphogenesis and organogenesis in particular is required to advance tissue engineering. Recent advancements in 3D ...

Simulation of the Earth's Electromagnetic Clearance System (DEMETER)

J. P. Pothin [1], N. Gosselin [1],
[1] Nexter Systems, France

DEMETER is a magnetic field replicator. This system is designed to deceive anti tank mines. Numerical simulation (using COMSOL Multiphysics® software) allows to indicate DEMETER's performance in various environment and various configurations. The study of the magnetic field provide also an overview of mine-clearing tools disturbances on the field generated by DEMETER.
