A Multiscale-Multiphysics Model for Axon Pathfinding Simulation, the Example of the Olfactory System

G. Naldi[1], G. Aletti[1], P. Causin[1]
[1]Dipartimento di Matematica ‘F. Enriques’, Università degli Studi di Milano, Milano, Italy

In the developing embryo, neurons form connections by projecting axons to appropriate target areas. The projection process includes neurite elongation, resulting from the assembly of new cytoskeletal material at the free end of the axon, a complex cascade of steering decisions, driven by ...

Scale-up Design of Ultrasound Irradiator for Advanced Oxidation Process (AOP) Using COMSOL Multiphysics® Simulation

Z. Wei[1]
[1]The Ohio State University, Columbus, OH, USA

Ultrasound is a promising green technology for the advanced oxidation process (AOP) since it adds no chemicals to the treated water. In this paper, COMSOL Multiphysics® was used as a tool to design and characterize an ultrasound irradiator with multi-stepped configuration, which aims to ... En savoir plus

Modeling CO2 storage Using Coupled Reservoir-Geomechanical Analysis

Modeling CO₂ storage Using Coupled Reservoir-Geomechanical Analysis

T.I. Bjørnarå, F. Cuisiat, E. Aker, and E. Skurtveit
Norwegian Geotechnical Institute(NGI), Oslo, Norway

The geomechanical effects related to CO2 injection into the Krechba formation at In Salah, Algeria, are considered through a coupled modeling approach to simulate simultaneously CO2 migration in the aquifer and the surrounding formations, as well as the poro-elastic stress changes ...

A Modular Platform for Cell Characterization, Handling, and Sorting by Dielectrophoresis

S. Burgarella[1], B. Dell’Anna[2], V. Perna[1], G. Zarola[2], and S. Merlo[2]

[1]STMicroelectronics, Agrate Brianza, MI, Italy
[2]Dipartimento di Elettronica, Università degli Studi di Pavia, Pavia, Italy

Dielectrophoresis (DEP) is a method for cell manipulation without physical contact in lab-on-chip devices, since it exploits the dielectric properties of cells suspended in a microfluidic sample, under the action of locally generated high-gradient electric fields. The DEP platform that ... En savoir plus

Underground Coal Fire Extinction Model Using Coupled Reactive Heat and Mass Transfer Model in Porous Media

S. Suhendra[1], M. Schmidt[1], and U. Krause[1]
[1]Laboratory II.2: “Flammable Bulk Materials and Dusts, Solid Fuels”, Federal Institute for Materials Research and Testing (BAM), Berlin, Germany

Green house gases emission associated with natural hazard of underground coal seam fire has been recognized as a worldwide problem leading to global warming threat. Therefore, in this paper a model to study underground coal fire is presented and the results will be devoted to strategic ... En savoir plus

A Study of Distributed Feed-Back Fiber Laser Sensor for Aeronautical Applications Using COMSOL Multiphysics

I. Lancranjan[1], C. Gavrila[2], S. Miclos[3], and D. Savastru[3]
[1]Advanced Study Centre - National Institute for Aerospace Research Elie Carafoli, Bucharest, Romania
[2]Technical University of Civil Engineering Bucharest, Romania
[3]National Institute R&D of Optoelectronics, INOE 2000, Bucharest, Romania

Distributed Feedback Fiber Laser (DFB-FL) sensors are increasingly used in aeronautical applications. One of the newest such applications consists in detecting the “transition” zone between laminar and turbulent air flow upon the extrados surface of an aircraft wing. In this specific ...

Numerical Study of a High Temperature Latent Heat Storage (200-300^oC) Using Eutectic Nitrate Salt of Sodium Nitrate and Potassium Nitrate

C.W. Foong, J.E. Hustad, J. Løvseth, and O.J. Nydal
Department of Energy and Process Engineering, Norwegian University of Science and Technology, Trondheim, Norway

In this study, a small scale direct solar thermal energy storage system with secondary reflector is designed and developed. The main advantage of thermal energy storage is that cooking can be carried out during the time when there is little or no sun shine. In addition, no heat transport ... En savoir plus

Hybrid FEM-BEM Approach for Two- and Three-Dimensional Open Boundary Magnetostatic Problems

A. Weddemann[1], D. Kappe[2], and A. Hütten[2]
[1]Research Laboratory of Electronics, Massachusetts Institute of Technology, Cambridge MA, USA
[2]Department of Physics, Thin Films and Physics of Nanostructures, Bielefeld University, Bielefeld, Germany

In principal, the calculation of the magnetic state inside a magnetic object requires the evaluation of the field in the entire unbounded space. With finite element methods restricted to finite domains, commonly auxiliary domains are employed which result in a non-physical cut-off. Not ... En savoir plus

Xylophone Bar Magnetometry and Inertial-grade MEMS Optimisation: a Multiphysics Approach

H. T. D. Grigg, and B. J. Gallacher
Microsystems Group
Newcastle University
Newcastle upon Tyne
Tyne and Wear, UK

This paper presents ongoing research aimed at development of a MEMS magnetometer capable of nanoTesla sensitivity. Such a device would pave the way for inertial-grade MEMS IMUs. A resonant sensor is proposed, based on a Xylophone Bar sense element, and is analysed both directly and via ... En savoir plus
