We study the evolution of recombination using a microscopic model developed within the frame of the theory of quantitative traits. Two components of fitness are considered: a static one that describes adaptation to environmental factors not related to the population itself, and a dynamic one...

An approach allowing the on-target computation of efficiency and yield of large (hundreds of kW), grid-connected photovoltaic (PV) parks is presented. An efficiency metric is used to trigger alarms and to plan maintenance interventions. An accurate simulation model of the system, that is capable...

We propose a two-dimensional computational model for deep landslides triggered by rainfall, based on interacting particles or grains. The model describes a vertical section of a fictitious granular material along a slope, in order to study the behavior of a wide-thickness landslide. The...

In this paper, first we present the experimental results about a small group of people exchanging private and public messages in a virtual community. Our goal is to study the cognitive network that emerges during a chat seance. We used the Derrida coefficient and the triangle structure under the...

A model for opinion formation and anticipation based on the match between hidden personal “preferences” and product qualities is presented. We assume that products and individuals are represented by means of vectors in an L-dimensional “taste” space. The opinion of an individual on a...

We study the statistics of the time evolution of the Game of Life. We recognize three different time regimes of which the most interesting one is the long time glider regime, which has properties typical of a critical state. We introduce mean field approximations able to give some insights on...

We investigate the finite size corrections to the equilibrium magnetization of an Ising model on a random graph with N nodes and Nγ edges, with 1γ≤2. By conveniently rescaling the coupling constant, the free energy is made extensive. As expected, the system displays a phase transition of the...
