Combining Simulation and Mean Field Analysis in Quantitative Evaluation of Crowd Evacuation Scenarioger crowds, but they prevent direct representation of dynamics occurring on the micro scale which may be more easily related to observations..In this work, we present and experiment a hierarchical approach which aims at conciliating the contrast through the combination of fine grained simulation and

A Cross-Layer Security Framework for Wireless Mesh Networks,eless mesh network with distributed network architecture, it is relatively fragile and vulnerable to attack. In this paper, we first analyze the characters of hybrid mesh network architecture. The security weaknesses of WMNs mainly reflected in the transmission channel, authentication, physical prot

On the cellular level, this is achieved by Na. extrusion or its vacuolar sequestration, decrease of the permeability of vacuolar and plasma membrane to Na. and, the last but not the least, better K. retention. Active Na. transport from cytosol to exterior or to

This book was designed to appear in 1987, 15 years after the publication of a now classic collection of essays in honor of George Katona (Strumpel et aI. , 1972), who throughout the fifties and sixties had been tirelessly trying to persuade economists o

Weiterhin wird dargelegt, wie die selbstst?ndige Aufarbeitung der vorhandenen Literatur in die Ableitung einer eigenen Forschungsidee münden kann. Schlie?lich wird aufgezeigt, wie aus dem Spannungsfeld zwischen praktischen Beobachtungen und theoriegeleiteten Erkl?rungsmustern eine Forschungsidee erwachsen kann.

Energy changes accompanying underground mining,underground opening by removal of supporting rock is mechanically equivalent to application of a set of tractions over a surface representing the excavation boundary. Thus typical excavation development practice is represented mechanically, by the impulsive application of these surface forces in the rock medium.
