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...

Yeld analysis is an activity common to all companies manufacturing semiconductor devices on an industrial scale and consists in identifying problems relating to the production cycle by analyzing the number and distribution of non-functioning chips on the wafer. This is an extremely expensive...

Prediction of various market indicators is an important issue in finance. This can be accomplished through computer models and related applications to finance, and in particular through Artificial Neural Networks (ANNs) which have been used in stock market prediction and exchange rates during...

La microbilogia predittiva (PFM – Predictive Food Microbiology) e' un’area multidisciplinare di ricerca della microbiologia alimentare. Essa implementa elementi fondamentali di matematica, microbiologia, ingegneria e chimica per sviluppare ed applicare modelli matematici e per predire la...

A VPN (Virtual Private Network) simulates a secure private network through a shared public insecure infrastructure like the Internet. The VPN protocol provides a secure and reliable access from home/office on any networking technology transporting IP packets. In this article we study the...

Wireless ad hoc single-rate environments typically use a Distance Vector routing with a metric based on hop-count minimization. In practice, the technique of minimizing the distance does not reward in the case of multirate, therefore it may be prefereable to use protocols privileging link...

Nel corso degli anni l'enorme e sempre crescente disponibilita' di informazioni, soprattutto con l'avvento di Internet, e le innumerevo- li innovazioni nell'ambiente software hanno portato la produzione di applicazioni multimediali ad essere una strategia educativa efficiente ed efficace. Le...
