This work remarks the need to carefully evaluate the real importance of each variable used in a multivariate analysis context, with particular regard to cases when an overall performance ranking is the main final purpose. In particular, both a preliminary transformation of variables – aimed at...

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...

In the last 20 years, the concept of ‘Sustainable Development’ (SD) has become very popular and wide spread in the world. In particular, the environmental dimension of SD asks for new ways to accomplish enhanced quality of life with reduced environmental impact. As a consequence, innovations...

Learning is a continuous process, without end, which takes place throughout life, and is the result of the interaction of an individual with a physical external environment, a social context or with herself. In what new technologies may help improving and making more effective the interaction of...

This paper provides a real option methodology for evaluating R&D investment opportunities assuming that potential competitors can en- ter in the market. As it is well known, R&D investments are made often in a phased manner and so each stage creates an opportunity (option) for subsequent...

In this deliverable we first present a general description of the theoretical framework within which the model is developed. Subsequently, we present a detailed specification of the social network model paying due attention to specification of various actors, their social interaction rules and...

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...

We propose an algorithm for computing "main stable sets" recently introduced by Ciardiello, Di Liddo (2009) on effectiveness form coalitional games modeled through a directed pseudograph. The algorithm is based upon a graph traversing method exploring extended paths minimal in coalitions and we...

In this work we explore some properties of on-Neumann-Morgenstern stable sets in the environment of multidimensional spatial voting situations. In our framework, the set of outcomes under consideration is some compact and convex subset of some finite dimensional Euclidean space and any majority...

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...
