Shear deformations of slender reinforced concrete walls under seismic loading

Katrin Beyer, Alessandro Dazio

Experimental results gained from quasi-static cyclic tests on 34 slender structural reinforced concrete walls available in the literature are used to examine the shear deformations for displacement demands in the inelastic range. Based on these results the ...

Global simulations of tokamak microturbulence: finite beta effects and collisions

Laurent Villard, Stephan Brunner, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Thibaut Vernay

In this paper, we present global nonlinear gyrokinetic simulations including finite beta effects and collisions in tokamak geometry. Global electromagnetic simulations using conventional delta-f particle in cell methods are very demanding, with respect to ...

Intensification of Gas/Liquid Chemical Synthesis Using Microreactors and New Operating Windows

Anne-Laure Dessimoz

Process intensification is a vibrating topic in the field of chemical engineering. Its aim is to develop processes and methods with increased performance for a given chemical transformation at decreased energy consumption and waste production. Among all me ...

Operational macroscopic modeling of complex urban road intersections

Gunnar Flötteröd

This article describes a new approach to the macroscopic first order modeling and simulation of traffic flow in complex urban road intersections. The framework is theoretically sound, operational, and comprises a large body of models presented so far in th ...

Friction force: from mechanics to thermodynamics

Christian Gruber, Christian Ferrari

We study some mechanical problems in which a friction force is acting on a system. Using the fundamental concepts of state, time evolution and energy conservation, we explain how to extend Newtonian mechanics to thermodynamics. We arrive at the two laws of ...

Biothermodynamics of live cells: a tool for biotechnology and biochemical engineering

Urs von Stockar

The aim of this contribution is to review the application of thermodynamics to live cultures of microbial and other cells and to explore to what extent this may be put to practical use. A major focus is on energy dissipation effects in industrially relevan ...

Spintronics: Conceptual Building Blocks

Jean-Philippe Ansermet

The purpose of this introduction to spintronics is to provide some elementary description of its conceptual building blocks. Thus, it is intended for a newcomer to the field. After recalling rudimentary descriptions of spin precession and spin relaxation, ...

Thermal effects in the Long-Term Monitoring of Bridges

Olivier Burdet

Daily and seasonal temperature variations induce deflections of bridges. The amplitude of these moments is significant in comparison with the yearly increment caused by irreversible long-term deflections. To improve the quality of the interpretation of mon ...

Kinetic modeling of the central carbon metabolism of Escherichia Coli

Vassily Hatzimanikatis, Ljubisa Miskovic

Precise information about kinetic properties of enzymes within a biochemical network is a necessary ingredient of any successful metabolic engineering design. Such information inevitably involves uncertainty due to changes in cellular and process parameter ...
