A genetic algorithm in a schedule problem with special constraints
(2011-07-08)Ramírez (2001) introduced the generalized robust coloring problem (GRCP), this problem lets solve timetabling problems which considers constraints such as: two events can not be assigned at the same time and there must be ... -
A Hybrid Random Number Generator(HRNG)
(2011-07-29)The purpose of this paper is to present a novel Hybrid Random Number Generator (HRNG). Here “hybrid” refers to the fact that to construct this generator it is necessary to use 1)physical components – texts – and a physical ... -
Geostatistical Spatio-Time model of crime in el Salvador: Structural and Predictive Analysis
(2011-07-26)Today, to study a geospatial and spatio-temporal phenomena requires searching statistical tools that enable the analysis of the dependency of space, time and interactions. The science that studies this kind of subjects is ... -
Parallelization of a Quantum-Classic Hybrid Model For Nanoscale Semiconductor Devices
(2011-07-26)The expensive reengineering of the sequential software and the difficult parallel programming are two of the many technical and economic obstacles to the wide use of HPC. We investigate the chance to improve in a rapid way ... -
Preference of effective Factors in suitable selection of Microtunnel boring machines (mtbm) by using the fuzzy analytic hierarchy process (fahp) approach
(2011-07-08)The development of underground infrastructure, environmental concerns, and economic trend is influencing society. Due to the increasingly critical nature of installations of utility systems especially in congested areas, ... -
search of hadamard matrices by turyn sequences
(2011-07-08)In this paper we study the Hadamard matrices and some algorithms to generate them. We review some theoretical aspects about Hadamard's conjecture, which asserts that every positive integer multiple of 4 is a Hadamard number. ... -
Sensor Fusion Using Entropic measures of Dependence
(2011-07-26)As opposed to standard methods of association which rely on measures of central dispersion, entropic measures quantify multivalued relations. This distinction is especially important when high fidelity models of the sensed ...
