Schwerpunkte dieses Vortrages bilden die Verknüpfungen folgender Themenkomplexe: • Werkstoffwissenschaft • Energieverfahrenstechnik • Qualitätsmanagement • Polyoptimierung Für derart umfassende Aufgabenstellungen gibt es zur Zeit keine Softwarelösungen. So ist z.B. die Kundenforderung nach Garantie erhöhter Schlagarbeit bei stark abgesenkten negativen Temperaturen in keinem ...

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 ...

Numerical Methods used in Biomedical Technology

Klaus Liefeith
Institut für Bioprozess- und Analysemesstechnik e.V.
Heiligenstadt

Breakthroughs in biomedicine and IT have provided a wealth (mountain) of data where the key post-genomic challenge is to transform this data into information that can be used to determine biomaterial function. Biomaterial functions arise from complex nonlinear interactions between biological processes occurring over multiple spatial and temporal scales Gaining an understanding of these ...

Numerical simulation of separation flows with FEMLAB 3.1

Carlo Gualtieri
University of Napoli Federico II
Naples, Italy

Flow separation is a common and interesting phenomenon in fluid mechanics with significant effects in practical applications. Thus, it has been the focus of intensive study for many years. The objective of this presentation is to investigate laminar separation flows over a backward-facing step and over a rectangular trench using COMSOL. --------------------------------- Carlo Gualtieri ...

Mathematical Modeling of Autoregulation using Finite-Element Method

Aleksandar Jeremic
Assistant Professor
Department of Electrical and Computer Engineering
McMaster University
Hamilton, Canada

In this presentation, cerebral blood flow (CBF) is modeled using a mathematical model, a statistical model and numerical examples. In the mathematical model, blood flow is described using Navier-Stokes equations. In the statistical model, the experiments or the data measurement process is simulated and to study how the noise in the measurements affects the ability to estimate the parameters, ...

The Unroutinary Loads on the LBT Adaptive Secondary Mirror

C. Del Vecchio
INAF-OAA, Firenze, Italy

The thin shell of the LBT Adaptive Secondary Mirror has been manufactured, optically polished, and delivered. The operations and tests required before finally mounting it on the telescope have to be run very carefully, as they imply loads completely different from the ones of the adaptive operational modes - studied in the past with very encouraging results. Deformations and stresses that occur ...

Numerical Simulation of a Dezincification Process Controlled by Electromagnetic Fields

2Ecole Centrale de Lille, Villeneuve D'Ascq, France

A parametric simulator for a dezincification process industrial device analysis has been developed. The device is built upon a COMSOL Multiphysics magneto-thermo-hydraulic coupled model in a cylindrical coordinate system.We study effects of electromagnetic forces on a cast iron load and consequently on Zn gas bubbles trajectories included in the metal.Trajectories are obtained according to mass ...

Design of heat flux microsensor assisted by COMSOL for the study of energy transfer on Si and Cu thin samples

L. Bedra, N. Semmar, A.-L. Thomann, R. Dussart, J. Mathias, and Y. Tessier
GREMI, CNRS-Université d'Orléans, Orléans, France

A commercial heat probe is used for energy transfer measurements on copper and silicon substrates. To do so, the micro sensor has to be calibrated under high vacuum (~10-7 mbar), using a homemade black body as a heat source.Although the HFM is cooled at 5 oC, the solid surface temperature is unknown as the thermal contact resistance. Thus, COMSOL simulations are also used to obtain reliable ...

Microband Electrodes in Microchannels: Edge Diffusion and Wall Effects

N. Godino1, F. J. del Campo2, and F. X. Muñoz1
1Instituto de Microelectrónica de Barcelona, IMB-CNM-CSIC, Barcelona, Spain
2Institut de Biotecnologia i Biomedicina "Vicent Pallar Palasi", Universitat Autónoma de Barcelona, Barcelona, Spain.

Microfluidics enables the miniaturization and integration of sensors into advanced analytical devices. Electrochemical detection is currently one of the preferential techniques of use in microfluidic devices due to its sensitivity, low cost and compatibility with new microfabrication techniques. In this work, we first model the electrochemical response of a set of microband electrodes placed ...
