On the Influence of Cancellous Bone Structure upon the Electric Field Distribution of Electrostimulative Implants
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 ... En savoir plus
Numerical Modeling of Sampling Airborne Radioactive Particles Methods from the Stacks of Nuclear Facilities in Compliance with ISO 2889
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 ... En savoir plus
Modelling of Heat and Moisture Transport in a Corrugated Board Stack
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 ... En savoir plus
Field Joint Coatings for Deep Sea Pipelines
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
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 ... En savoir plus
Heterodimensional Charge-Carrier Confinement in Sub-Monolayer InAs in GaAs
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 ... En savoir plus
Rheological and Topographical Controls on Deformation Due to a Shallow Magma Reservoir
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 ... En savoir plus
Sound Field Analysis of Monumental Structures by the Application of Diffusion Equation Model
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 ... En savoir plus
Control of Real Distributed Parameter Systems Modeled by COMSOL Multiphysics® Software
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 ... En savoir plus
Influence of a Refurbishing on an Old Residential Building’s Wall in Paris in Summer: Mass and Heat Transfer Approach
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 ... En savoir plus
