We propose a new global optimization method (Simulated Tempering) for simulating effectively a system with a rough free energy landscape (i.e. many coexisting states) at finite non-zero temperature. This method is related to simulated annealing, but here the temperature becomes a dynamic variable, and the system is always kept at equilibrium. We analyze the method on the Random Field Ising Mode...

A Kallen-Lehman approach to 3D Ising model is analyzed numerically both at low and high temperature. It is shown that, even assuming a minimal duality breaking, one can fix three parameters of the model to get a very good agreement with the MonteCarlo results at high temperatures. With the same parameters the agreement is satisfactory both at low and near critical temperatures. How to improve t...

Huge amount of textual information available in firms and institutions triggers the need for robust textual data analysis systems. A new field called text-mining has the goal of discovering hidden information and knowledge structuring in texts. Statistical methods coupled with natural language processing can give some answers to this kind of problems. We have developed a module of term clusteri...

This paper presents a Phantom Go program. It is based on a MonteCarlo approach. The program plays Phantom Go at an intermediate level.

Abstract Precision electron spectrometry in the keV range has always been considered a challenging task. The reconstruction of original energy from detected signal is not trivial because multiple effects modify kinetic along its path. If correctly accounted for, these can spoil and bias reconstructed with dramatic reduction accuracy precision. In this paper we address one most critical aspects ...

We have computed the light transport in a bre in the geometrical optics approximation. The aim of this study is to compare the performances of single and double clad bres and to outline possible improvements to bre design.
