Some Aspects in n-dimensional almost Periodic functions iii
Some Aspects in n-dimensional almost Periodic functions iii
(2011-04-29)
The properties of almost periodical functions and some new results have been published in [CA1], [CA2] and [CA3] In this paper we show some new definitions in order to analize some singularities. For this functions we find ...

Problemas matemáticos sugeridos por la genética y la ecología de poblaciones
(2009-02-20)
The main goal of the present work is to show a paralellism between the equationsin Physics and Mathematics, and some problems generated in another branch whichcould be called Mathematical Biology. The article is divided ...
Predicción estacional del clima en Centroamérica mediante la reducción de escala dinámica. Parte II: aplicación del modelo MM5V3
(2009-02-27)
In the first part of this work it was determined that general circulation model(GCM) ECHAM4.5 shows more ability than CCM3.6 to simulate key climate featuresof Central America. For such reason, output from ECHAM4.5 was ...
Métodos de punto interior para optimización cuadrática convexa con matrices no definidas positivas
Métodos de punto interior para optimización cuadrática convexa con matrices no definidas positivas
(2009-02-25)
In this article a modification of the recursive algorithm of Cholesky is obtainedthat allows the factorization of Semi Definite Positive Matrices, even though theseare not positive defined, without increasing the computational ...
Shipment consolidation by terminals and vehicles
Shipment consolidation by terminals and vehicles
(2009-02-27)
This project designs and implements a new module in a logistics analysis tool called”Logistika” that was developed by some graduate students in ASU. Initially, Logistikaonly had available a “Plant location module”, but ...
Una caracterización sobre las soluciones para el problema de reaprovisionamiento conjunto
Una caracterización sobre las soluciones para el problema de reaprovisionamiento conjunto
(2009-02-20)
In this paper an introduction is given to a multiple-item inventory problem, knownas the Joint Replenishment Problem (JRP). This is a real world problem which hasbeen extensively studied. The JRP has a continuous decision ...
A mimetic finite difference method using Crank-Nicolson scheme for unsteady diffusion equation
(2010-04-09)
n this article a new mimetic finite difference method to solve unsteady diffusionequation is presented. It uses Crank-Nicolson scheme to obtain time approximationsand second order mimetic discretizations for gradient ...
The Black-Scholes type financial models and the arbitrage opportunities
The Black-Scholes type financial models and the arbitrage opportunities
(2009-02-25)
By using the conservation laws concept, we study certain financial models similar tothe Black–Scholes model. We show that without complement limitations such modelscan have two or more volatilities. This fact imposes several ...
search of hadamard matrices by turyn sequences
Búsqueda de Matrices de Hadamard a través de Secuencias de Turyn
(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. ...
Preference of effective Factors in suitable selection of Microtunnel boring machines (mtbm) by using the fuzzy analytic hierarchy process (fahp) approach
Preferencia de Factores de Efectividad en la Selección Apropiada de Máquinas Taladradoras de Microtúnel (MTBM) Usando el Enfoque del Proceso Jerárquico Analítico Difuso (FACH)
(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, ...
