The use of space discretization for autonomous virtual humans

A motion planning algorithm for automatic path computation for an autonomous virtual human in an environment of obstacles is presented. The environment is discretized and an optimum path in terms of number of cells is computed using A* search technique ...

VHDL analog and mixed-signal extensions through examples

Alain Vachoux

VHDL 1076.1 denotes an effort to enhance the IEEE VHDL 1076 standard with analog and mixed-signal capabilities. In November 1995, the development of the extensions was nearing completion. An IEEE ballot to adopt the extensions as a new IEEE standard should ...

Melting of the Higgs vacuum: Conserved numbers at high temperature

We discuss the computation of the grand canonical partition sum describing hot matter in systems with the Higgs mechanism in the presence of non-zero conserved global charges. We formulate a set of simple rules for that computation in the high-temperature ...

On the need for multipermutations: cryptanalysis of MD4 and SAFER

Serge Vaudenay

Cryptographic primitives are usually based on a network with boxes. Schnorr and Vaudenay (1994) claimed that all boxes should be multipermutations. In this paper we investigate a few combinatorial properties of multipermutations. We argue that boxes which ...

Some planar isospectral domains

Klaus-Dieter Semmler

The authors give a number of examples of two noncongruent isospectral domains in the plane and a particularly simple method of proof. One of their examples is a pair of domains that are not only isospectral but homophonic, i.e. each domain has a distinguis ...

Heat Exchanger Network (HEN) costs and performances estimation for multi-period operation

François Maréchal, Francesca Palazzi, Raffaele Bolliger

This paper addresses the problem of modeling and estimating the cost of the heat exchanger network (HEN) in multi-period operation using pinch technique concepts. The developed method improves the vertical heat exchanges technique originally proposed by Ah ...
