An algorithm of "Simulated Annealing" for solving scheduling problems is presented. The issues related to scheduling are discussed, together with the Simulated Annealing approximation method and its main parameters (freezing, temperature, cooling, number of neighbourhoods to explore), the...

The study of Artificial Neural Networks derives from first trials to translate in mathematical models the principles of biological processing. An Artificial Neural Network deals with generating, in the fastest times, an implicit and predictive model of the evolution of a system. In particular,...

Il ruolo dei canali virtuali nella distribuzione dei servizi finanziari rappresenta uno degli aspetti pi rilevanti nella ristrutturazione della rete distributiva bancaria e finanziaria tradizionale. La banca virtuale modifica i processi e le modalita' di produzione mediante la tecnologia,...

The creation of new programming languages, capable of fully deploying the new technological innovations and operating environments, requires more and more accurate and affordable analysis. In this study, a technique for the generation of formal models for the specification of the semantics of...

The need to store data and information permanently, for their reuse in later stages, is a very relevant problem in the modern world and now affects a large number of people and economic agents. The storage and subsequent use of data can indeed be a valuable source for decision making or to...

Because the CPU is a very expensive resource in mobile ad hoc networks (MANETs), it is very important to consider the overhead introduced in a routing protocol. Many theories have been hypothesized with the aim of minimizing it. But how much is the energy consumption from a network node’s...

Le possibili applicazioni della modellizzazione e simulazione nel campo della Bioinforma- tica sono molto ampie. Le applicazioni spaziano dalla comprensione dei percorsi metabolici di base all'esplorazione della variabilita genetica. I biologi molecolari necessitano di robusti strumenti di...

The photovoltaic (PV) industry in Italy has already crossed the threshold of 1 GW of installed capacity. Currently there are approximately 70,000 certified facilities in operation for a power generation of 1,300 GWh/year. With these figures, Italy has become the second country in Europe for PV...

A very significant issue today concerns the problem of air pollution caused mainly by human activity. The statistics show that most of the pollutants in the atmosphere is due to emissions caused by anthropogenic factors (e.g. power and industrial plants, traffic and combustion phenomena in...
