Descripción de dos métodos de rellenado de datos ausentes en series de tiempo meteorológicas
(2009-02-27)
Se presentan dos metodolog´?as para el rellenado de datos ausentes, enfocadas haciasu uso en series de tiempo geof´?sicas. La primera se basa en la descomposici´on encomponentes principales de la matriz de correlaci´on de ...
Un procedimiento de fuerte reducción de las dimensiones del RCPS/Pi
Un procedimiento de fuerte reducción de las dimensiones del RCPS/Pi
(2009-02-27)
Recently, in the field of project scheduling problems the concept of partially renewableresources has been introduced. Theoretically, it is a generalization of both renewable and non-renewable resources. From an applied ...
El método Statis como alternativa para detectar "response shift" en estudios de calidad de vida relacionada con la salud
El método Statis como alternativa para detectar "response shift" en estudios de calidad de vida relacionada con la salud
(2009-02-27)
After evaluating problems in conceptualisation of Quality of Life outcomes andestablishing an operational definition of HRQoL, we focus the attention on the different dimensions of Response Shift and the theoretical Models ...
Indices of regularity and indices of randomness for m-ary strings
Indices of regularity and indices of randomness for m-ary strings
(2009-02-27)
The notions “regularity index” and “randomness index” previously introduced forbinary strings (2-ary) have been modified slightly and generalized for m-ary strings(m = 2, 3, 4, . . .). These notions are complementary and ...
A multistep fundamental solution scheme for modeling groundwater flow
(2009-02-27)
A new numerical scheme for solving transient pressure in a confined aquifer ispresented. It is based on the fundamental solution method (FSM) and it combinesfree Green functions, superposition principle, and singular value ...

Árboles de clasificación para el análisis de gráficos de control multivariantes
(2009-02-27)
In statistical quality control, one of the most widely used tools are the controlcharts. The main problem of the multivariate control charts lies in that they onlyindicate that a change in the process has happened, but ...
The BPS preconditioner on Beowulf cluster
The BPS preconditioner on Beowulf cluster
(2009-02-27)
This work presents the implementation on a Linux Cluster of a parallel preconditionerfor the solution of the linear system resulting from the finite element discretizationof a 2D second order elliptic boundary value problem. ...
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 ...
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 ...
Minimization of the first eigenvalue in problems involving the bi-laplacian
Minimization of the first eigenvalue in problems involving the bi-laplacian
(2009-02-27)
This paper concerns the minimization of the first eigenvalue in problems involvingthe bi-Laplacian under either homogeneous Navier boundary conditions or homogeneousDirichlet boundary conditions. Physically, in case of N ...
