Flow behaviour of phosphorus-deoxidised copper in plane-strain hot extrusion with an insertion in the die has been studied through a finite-element model consisting of fluid dynamics and heat transfer approaches. The billet material is considered as rigid-visco-plastic and rate-sensitive. A dynamic viscosity, which is strain-rate and temperature dependent, has been integrated into the model. ...

This presentation shows a number of models of electrokinetic behaviour, each differentiated by a specific assumption. The purpose is to show how such assumptions can lead to varying results in elektrokinetic simulations. --------------------------------- Keynote speaker's biography: Professor Meinhart completed his Ph.D and Postdoctoral work at the University of Illinois in June of 1995. At ...

Hochspannungsimpulstransformatoren werden bei Ottomotoren zur Entzündung des Kraftstoff- Luft-Gemischs eingesetzt. Aktuelle Fahrzeuge sind mit zylinderselektiver Zündung ausgerüstet, so dass für jeden Zylinder ein Zündtransformator benötigt wird. Dieser ist direkt über der Zündkerze positioniert und stellt die benötigte Hochspannung sowie eine ausreichende Funkenenergie zur Verfügung, ...

This note is devoted to a domain decomposition method solving the Helmholtz equation in the frequency domain. We need to perform this global computation as a sequence of local computations, each computation being performed on a single subdomain, without any knowledge of the geometry and meshing of the other subdomains. This is useful when the global geometry is too big to be stored in a single ...

In the quest for a higher data storage capacity, different solutions for the future generations of optical discs (after the Blu-ray format, BD) are under investigations. An increase of the NA beyond 0.85 (NA of the BD format) requires the use of near field optics with all the difficulties inherent to those techniques (fine control of the distance between the optical head and the media). Today ...

As biologists uncover the structural and functional complexity of living organisms, it is increasingly clear that mathematical models are needed to synthesize experimental data and predict biological responses to external stimuli. Bioengineers are well-suited to develop such models and to add mechanics, fluid flow and other physical cues to the understanding of biological structure and ...
