On the Influence of Cancellous Bone Structure upon the Electric Field Distribution of Electrostimulative Implants

U. Zimmermann[1], R.Bader[2], U. van Rienen[1]
[1]Institute of General Electrical Engineering, University of Rostock, Rostock, Germany
[2]Department of Orthopaedics, University Medicine Rostock, Rostock, Germany

Since the 1980s, the accelerating effect of electromagnetic fields on bone regeneration is used to treat complicated fractures and bone diseases. At the University of Rostock, an electrostimulative hip revision system is developed, basing on the method of Kraus-Lechner. This method ... Mehr lesen

Numerical Modeling of Sampling Airborne Radioactive Particles Methods from the Stacks of Nuclear Facilities in Compliance with ISO 2889

P. Geraldini[1]
[1]Sogin Spa, Rome, Italy

The main objective of this study is to verify the compliance of an ongoing nuclear facilities stack design with the ISO 2889 requirements, during normal and off-normal conditions. In particular, with the numerical simulations, they have been identify well-mixed sample locations along the ... Mehr lesen

Modelling of Heat and Moisture Transport in a Corrugated Board Stack

M. Xynou[1]
[1]KTH Royal Institute of Technology, Stockholm, Sweden

Corrugated board is produced on a machine where the corrugated medium is glued between two flat paper surfaces, the liners. The board is cut into sheets and stored in a stack until suitable moisture content has been reached. The sheets are then cut and creased into blanks for the ... Mehr lesen

Field Joint Coatings for Deep Sea Pipelines

R. Verhelle[1], L. Van Lokeren[1], S. Loulidi[1], H. Boyd[2], G. Van Assche[1]
[1]Physical Chemistry & Polymer Science, Vrije Universiteit Brussel, Brussels, Belgium
[2]Heerema Marine Contractors, Leiden, The Netherlands

COMSOL Multiphysics® software is used to model the field joint application process on carbon steel pipelines for deep sea crude oil transportation, taking into account not only heat transfer, cure kinetics, and crystallization, but also thermal, cure and crystallization shrinkage and the ...

Void Shape Evolution of Silicon: Level-Set Approach

C. Grau Turuelo[1], C. Breitkopf[1]
[1]Technische Universität Dresden, Dresden, Germany

The void shape evolution of silicon is a process driven mainly by surface diffusion which leads to a geometrical transformation of trenches etched in silicon wafers due to surface energy minimization. The temperature, the ambient gas and the annealing time affect the velocity of the ... Mehr lesen

Heterodimensional Charge-Carrier Confinement in Sub-Monolayer InAs in GaAs

S. Harrison[1], M. Young[1], M. Hayne[1], P. D. Hodgson[1], R. J. Young[1], A. Strittmatter[2], A. Lenz[2], U. W. Pohl[2], D. Bimberg[2]
[1]Department of Physics, Lancaster University, Lancaster, UK
[2]Institut für Festkörperphysik, Berlin, Germany

Low-dimensional semiconductor nanostructures, in which charge carriers are confined in a number of spatial dimensions, are the focus of much solid-state physics research, offering superior optical and electronic properties over their bulk counterparts. Both two-dimensional (2D) and zero ... Mehr lesen

Rheological and Topographical Controls on Deformation Due to a Shallow Magma Reservoir

J. H. Johnson[1]
[1]University of Bristol School of Earth Sciences, Bristol, UK

The use of high-resolution topography in the finite element model demonstrates that deformation from a shallow pressure source can be dramatically affected by overlying relief, not only in magnitude, but also in azimuth. This result is significant as it allows traditionally anomalous ... Mehr lesen

Sound Field Analysis of Monumental Structures by the Application of Diffusion Equation Model

Z. S. Gul[1], N. Xiang[2], M. Caliskan[3]
[1]Department of Architecture, Middle East Technical University, Ankara, Turkey
[2]School of Architecture, Rensselaer Polytechnic Institute, Troy, NY, USA
[3]Department of Mechanical Engineering, Middle East Technical University, Ankara, Turkey

Sound energy distribution patterns within enclosed spaces are the basic concerns of architectural acoustics. Energy decays are analyzed for major acoustical parameter estimations, while spatial energy distribution and flow vectors are indicative in the analysis of sound energy ... Mehr lesen

Control of Real Distributed Parameter Systems Modeled by COMSOL Multiphysics® Software

C. Belavý[1], G. Hulkó[1], S. Lipár[1], B. Barbolyas[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, first a basic concept of the engineering approach for modeling and control of distributed parameter systems (DPS) based on interpretation of controlled systems as lumped input and distributed output systems (LDS) is introduced. Next, FEM modeling of temperature fields in ... Mehr lesen

Influence of a Refurbishing on an Old Residential Building’s Wall in Paris in Summer: Mass and Heat Transfer Approach

K. Azos-Diaz[1], B. Tremeac[2], F. Simon[2], D. Corgier[2], C. Marvillet[1]
[1]Laboratoire de Chimie Moléculaire, Génie des Procédés Chimique et Energétique, Paris, France
[2]MANASLU Ing., Savoie Technolac, Le Bourget du Lac, France

The implementation of thermal insulation in old residential building walls could compromise the hygrothermal behavior of the construction, especially in summer time when it is placed inside. A bad installation of insulation could have consequences on the quality of indoor air conditions ... Mehr lesen
