L'entrevista: Gabriel, escultor. "L'art té sentit, no significat"

Som a Palau de Santa Eulàlia, a la casa taller de l'escultor Gabriel. És autor de l’escultura De Profundis al frontispici de la Facultat d’Educació i Psicologia i de l’Escola Universitària d’Infermeria. Comença l'entrevista mentre sona un carilló mogut pel vent. Tot i l'anarquia del seus moviments, els sons que produeix els apercebem com una melodia

Bandwidth allocation based on real time calculations using the convolution approach

This paper focuses on one of the methods for bandwidth allocation in an ATM network: the convolution approach. The convolution approach permits an accurate study of the system load in statistical terms by accumulated calculations, since probabilistic results of the bandwidth allocation can be obtained. Nevertheless, the convolution approach has a high cost in terms of calculation and storage requirements. This aspect makes real-time calculations difficult, so many authors do not consider this approach. With the aim of reducing the cost we propose to use the multinomial distribution function: the enhanced convolution approach (ECA). This permits direct computation of the associated probabilities of the instantaneous bandwidth requirements and makes a simple deconvolution process possible. The ECA is used in connection acceptance control, and some results are presented
