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...

In this paper the simulation and design of a quantum-film electro-optic switch is considered. This photonic device, is made from a new organic dipolar material called MNA or 2-methyl-4 nitroaniline, which possesses a high merit in comparison with it's inorganic counterparts (e.g. LiNbO3, GaAs, InSb, Quartz, etc). Montecarlo method is used to simulate the photon-it-electron interaction in this m...

Linear complexity and linear complexity profile are important characteristics of a sequence for applications in cryptography and MonteCarlo methods. The nonlinear congruential method is an attractive alternative to the classical linear congruential method for pseudorandom number generation. Recently, a weak lower bound on the linear complexity profile of a general nonlinear congruential pseudor...

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

Bctusbdu ̋In this paper we want to minimize passengers waiting times at the bus stops by making buses wait at a stop. We compare a simple rule based approach to a MonteCarlo method for this problem. When allocated enough time, the Monte-Carlo method gives better results. If the passengers arrivals and the bus travel times are known, the best algorithm is nested Monte-Carlo search with memorizati...

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.
