Control of Preheating Process of Casting Die as Distributed Parameter System

C. Belavý[1], G. Hulkó[1], K. Ondrejkovic[1], and P. Zajícek[1]
[1]Institute of Automation, Measurement and Applied Informatics, Faculty of Mechanical Engineering, Slovak University of Technology in Bratislava, Bratislava, Slovak Republic

In the paper distributed parameter system models in the form of lumped-input/distributed-output systems are introduced and modeling of temperature fields of the die in the benchmark casting plant is presented. Temperature fields were modeled and studied using a finite element method based software package COMSOL Multiphysics and numerical models in the form of a lumped-input/distributed-output ...

Finite Element Analysis of Microscale Luminescent Glucose Sensors in the Skin Dermis

S. Ali[1], and M. McShane[1]
[1]Department of Biomedical Engineering, Texas A&M University-College Station, Texas, USA

With the rising predominance of diabetes, successful management of blood glucose levels is increasingly important. Key efforts have focused on the development of optical microscale glucose sensing systems based on the encapsulation of glucose oxidase within microspheres coated with polyelectrolyte multilayer nanofilms. A two-substrate mathematical model of microscale optical glucose sensors in ...

Multiphysics Modelling of an Electromagnetic Horn Dedicated to a Neutrino Superbeam Facility

F. Osswald, and G. Gaudiot
IPHC, Univ. Louis Pasteur, Strasbourg

This paper presents thermo-mechanical and electromagnetic computational results in the time-harmonic and transient domains. This includes the stress analysis induced by the magnetic field and resulting pressure, the Joule heating with skin effects and the corresponding deformation.

The hyporheic zone is defined as an area where water and matter exchange through the sand, gravel, sediments and other permeable soils under and beside streams. Its impact on the hydro-system function is determined by the proportion of subsurface biogeochemical reactions and the fluxes of water exchanging with the hyporheic zone and flowing through the porous sediments. The objective of our ...

Virtual Prototyping

B. Engquist
University of Texas, Austin

During the past 50 years, Computational Science has developed as its own branch of mathematics. This development was mainly initiated by the progress of modern computers. Todays modeling of physical phenomena must not only account for the computational time but also the time engineers spend on setting up the computation. This in turn has introduced new fields, such as human interaction, to ...

Designing an Array of Nanocalorimeters for Screening Biochemical Interactions

F. Torres
Palo Alto Research Center

In this presentation we present our analysis of the PARC Nanocalorimeter. Calorimetry is basically the measuring of heat of chemical reactions or physical changes. Nanocalorimetry is Calorimetry at the Nanometer scale. The PARC Nanocalorimeter is a special type of Calorimeter, it consists of arrays of Nanocalorimeters. The PARC Nanocalorimeter is intended to be used for screening biochemical ...

Educational and Industrial Multiphysics Modeling in Czech Republic

K. Bittner

Humusoft was founded in 1990 and has been a representative for COMSOL since 1999, for several countries in Eastern Europe. In this presentation we begin with a short overview of the and historical milestones for Humusoft. The essence of this presentation concerns the wide ranging branches in which COMSOL Multiphysics is used from the Automotive industry to the Medical. From the corporate ...

NASA's Life Support Developments

Jim Knox
Technical Manager
NASA Marshall Space Flight Center
Huntsville, AL

This presentation deals with the investigation of new methods for the adsorption of carbon dioxide and water vapor from manned spacecraft atmospheres. The presentation touches not only the modeling of such methods, but also the important applications. Apart from modeling results on water adsorption and determination of heat transfer coefficients, an historical overview of spacecraft atmosphere ...
