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 ...
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 ...
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 ...
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 ...
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 ...

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. ...
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 ...
Detection of unobserved heterogeneity with growth mixture models
Detection of unobserved heterogeneity with growth mixture models
(2009-02-27)
Latent growth curve models as structural equation models are extensively discussedin various research fields (Duncan et al., 2006). Recent methodological and statisticalextension are focused on the consideration of unobserved ...
