Ad hoc networks are expected to be used in many different situations. A common characteristic among these situations is that the nodes have to cooperate with each other. This problem is particularly crucial, if each node is its own authority. Reckoning the ...
A formalized theory of alpha-conversion for the pi-calculus in Isabelle/HOL is presented. Following a recent proposal by Gabbay and Pitts, substitutions are modelled in terms of permutations, and alpha-equivalence is defined over all but finitely many name ...
The present paper presents an overview of the work of the RILEM Technical Committee 159-ETC on the engineering of the interfacial transition zone in cementitious composites. The object of this committee was to resolve the practical influences of the interf ...
Photodynamic therapy (PDT) is a new treatment modality which relies on a nonthermal light exposure of choroidal neovascularization (CNV) which has accumulated a photosensitizer, to produce a photochemical thrombosis. The aim of the present study was to dev ...
In this paper we investigate a new way of protecting block ciphers against classes of attacks (including differential and linear crypt-analysis) which is based on the notion of decorrelation which is fairly connected to Carter-Wegman's notion of universal ...
Recents studies have shown that the use of improvement techniques on welds allows an increase in the level of admissible fatigue strength (even more than 100%). The aim of this study was to collect and validate literature data, create a data base containin ...
Simple theory has been developed and illustrated elsewhere which allows estimation, firstly, of the mean depth of solute penetration from any sequence of infiltration and evapotranspiration events, and secondly, of the apparent dispersion about this mean d ...
Particle tagging in a tokamak provides an attractive method for studying transport mechanisms. The injection of test particles at the plasma edge and the subsequent measurement of the evolution of their concentration at the centre can be used to quantify t ...
The TCV Tokamak was designed to create a large variety of plasma shapes. Such a large flexibility requires high precision magnetic measurements with a good spatial coverage. This article gives a detailed description of the magnetic sensor geometry, fabrica ...
Gradual clogging of the apertures of nanostencils used as miniature shadow masks in metal evaporations can be reduced by coating the stencil with self-assembled monolayers (SAM). This is quantified by the dimensions (height and volume) of gold features obt ...
