This paper is concerned with a multiresolution approach to the piecewise-linear approximation of multivariate nonlinear continuous functions. The proposed technique has no restrictions on the number of variables the functions depend on, and is based on the use of piecewise-linear "hat" functions. The approximation levels are related to nested...

This paper proposes a method to find multiresolution piecewise-linear (PWL) approximations of multivariate continuous nonlinear functions defined over limited compact domains. The method is derived from the context of PWL prewavelets on arbitrary triangulations and is aimed to the circuit implementations of the obtained approximations. Two...

The requirement of better workers' psychophysical health and the wish to guarantee a correct comfort also during work activities, induce to consider the presence of significant pure tones also for the working spaces. However, the current European legislation regarding professional exposure to the noise of the workers, and namely the EU...

One of the most frequent accident scenario following a loss of containment during HazMat transportation or processing is represented by the dispersion of a dense gas release. Several dispersion models are available to this purpose, more or less rigorously accounting for gravity slumping, air entrainment and possible heat transfer. Under...
