Electro-Stimulating Implants for Bone Regeneration: Parameter Analysis on Design and Implant Position

Y. Su[1], R. Souffrant[1], D. Klüß[1], R. Bader[1], M. Ellenrieder[1], and H. Ewald[2]
[1]Department of Orthopaedics, University of Rostock, Rostock, Germany
[2]Department of General Electrical Engineering, University of Rostock, Rostock, Germany

A common clinical treatment is the application of alternating electromagnetic fields using a screw implant to the weak bone tissue within the femoral head, which speed up the bone regeneration in case of avascular necrosis of the femoral head . In our present work the bipolar induction ... Mehr lesen

Simulation Enquiries on Energy Transfer Efficiency in Stored Fluids

E. Zinterl, and G. Jakopic
JOANNEUM RESEARCH Forschungsgesellschaft mbH,
MATERIALS-Institute for Surface Technologies and Photonics
Weiz, Austria

Heating or cooling of stored fluids by thermal energy exchange with the enclosing walls may be enhanced by improving the efficiency of energy transfer; energy loss to the ambient is equalized for all simulations. Buoyancy driven internal natural convective flow is assumed to be the main ... Mehr lesen

Simulation of Electrochemical Etching of Silicon with COMSOL

A. Ivanov
Hochschule Furtwangen
Furtwangen, Germany

Electrochemical etching of silicon (anodization) is a process that can be used for etching of forms of nearly arbitrary shapes. The difficulty of applying the process for mass production is in the many parameters influencing the process, such as electrolyte concentration and temperature, ... Mehr lesen

Homogeneous Heating of Milk

A. Stahel, and A. Reichmuth
Berner Fachhochschule
Biel, Switzerland

When milk is taken out of a refrigerator it has to be heated up to 37°C. The standard solution is to put the bottle in a bath of warm water and wait. The goal is quickly to achive a uniform temperature of 37°C, without ever exceeding 40°C. Using COMSOL Multiphysics and a measurement ... Mehr lesen

Numerical Simulations of Ultrasonic Non Destructive Techniques of Masonry Buildings

S. Carcangiu[1], B. Cannas[1], M. Usai[1], and G. Concu[2]
[1]Department of Electric and Electronic Engineering, Cagliari, Italy
[2]Department of Structural and Infrastructural Engineering and Geomatics, Cagliari, Italy

An experimental program has been developed, with the purpose of evaluating the reliability in building diagnosis and characterization of an integrated analysis of several parameters, associated with acoustic waves propagating through the material. The Direct Transmission Technique has ... Mehr lesen

Finite Element Analysis of Equine Tooth Movement Under Masticatory Loading

M. Gardemin[1], M. Lüpke[1], V. Cordes[2], and C. Staszyk[2]
[1]Institute for General Radiology and Medical Physics, University of Veterinary Medicine Hannover, Hannover, Germany
[2]Institute of Anatomy, University of Veterinary Medicine Hannover, Hannover, Germany

Like humans, horses can develop a variety of dental problems. Different equine diseases occur in different areas of the equine cheek tooth or its surrounding tissues. With a realistic simulation of a chewing cycle it can be possible to link mechanical phenomena such as high stress in ... Mehr lesen

Numerical modelling of the damage potential of climate variations to a historic wooden cabinet

Z. Huijbregts, H. Schellen, and J. van Schijndel
Department of the Built Environment
Eindhoven University of Technology
Eindhoven, The Netherlands

The two wooden cabinets of Jan van Mekeren that are located in Amerongen Castle show comparable wood damage; in particular large cracks in the cabinet doors are clearly noticeable. It is assumed that these cracks were caused by bad indoor climate conditions in the castle. Combined ... Mehr lesen

Excimer Laser-Annealing of Amorphous Silicon Layers

J. Förster, and H. Vogt
Institute of Electronic Components and Circuits
University Duisburg-Essen
Duisburg, Germany

A one-dimensional model of Excimer Laser-Annealing of amorphous silicon layers which are irradiated with a KrF excimer laser is described. For realisation, the application mode heat transfer in solids is used. The model predicts a melt threshold for the energy density of the laser of 88 ... Mehr lesen

Modelling and Simulation of a Three-stage Air Compressor Based on Dry Piston Technology

M. Heidari, and P. Barrade
EPFL
Lausanne, Switzerland

The core of this modelling is to study heat transfer and fluid dynamics processes for a compression expansion system, and the main particularity is that heat transfer and air movement are due to the movement of the piston. We have implemented a \"moving mesh\" solver to compute the ... Mehr lesen

Improved Finite Element Modeling of Heat and Mass Transfers in Single Corn Kernels During Drying

A. J. Kovacs, and M. Nemenyi
University of West Hungary
Institute of Biosystems Engineering
Mosonmagyarovar
GYMS, Hungary

Our Institute at the West Hungarian University is dealing with modelling of heat physical treatments in agricultural (biological) materials. The essential key in order to gain accurate results is to know the driving forces during heat and mass transfers. In case of mass transfer ... Mehr lesen
