FJ-Invex control problem
(Elsevier, 2009)
This paper introduces a new condition on the functionals of a control problem and extends a recent characterization result of KT-invexity. We prove that the new condition, the FJinvexity, is both necessary and sufficient ...

Robust facility location
(Springer, 2003-11)
Let A be a nonempty finite subset of the plane representing the geographical coordinates of a set of demand points (towns, …), to be served by a facility, whose location within a given region S is sought. Assuming that the ...

Diseños muestrales uniformes apropiados para estimar la función de distribución poblacional empleando muestreo por conglomerados en una etapa
(Universidad de Salamanca, 2001)
Para estimar la función de distribución de una variable sobre una población finita, se propone el estimador de Horvitz-Thompson, lo que proporciona una estrategia muestral insesgada. La varianza de dicho estimador es una ...

Management Mathematics for european schools
(Universidad de Zaragoza, 2004)
Beyond the topics, the Mathematics folklore says that pupils think that this field is a boring, non-practical mental exercise, far apart from daily life. This thought is influencing the entire education system and even ...

Application of a new mathematical method for the estimation of the mean surface area to calculate the percolation threshold of Lobenzarit dissodium salt in controlled release matrices
(The Pharmaceutical Society of Japan, 2004-07)
One of the practical handicaps for the application of the percolation theory to estimate the percolation threshold of drugs in controlled release systems is the fact that the dissolution studies must be carried out so that ...

Partially ordered cooperative games: extended core and Shapley value
(Springer, 2008-02)
In this paper we analyze cooperative games whose characteristic function takes values in a partially ordered linear space. Thus, the classical solution concepts in cooperative game theory have to be revisited and redefined: ...

A Monte Carlo comparison of three consistent bootstrap procedures
(Taylor & Francis, 2009-04)
Since bootstrap samples are simple random samples with replacement from the original sample, the information content of some bootstrap samples can be very low. To avoid this fact, some authors have proposed several variants ...

Improving Interval Analysis Bounds by Translations
(Springer, 2003-08-26)
We explore how a simple linear change of variable affects the inclusion functions obtained with Interval Analysis methods. Univariate and multivariate polynomial test functions are considered, showing that translation-based ...

Center location problems on tree graphs with subtree-shaped customers
(Elsevier, 2008-08-06)
We consider the p-center problem on tree graphs where the customers are modeled as continua subtrees. We address unweighted and weighted models as well as distances with and without addends. We prove that a relatively ...
