On the Stability of a class of Polytopes of third order square matrices and stability radius
(2011-04-29)In this work we investigate the stability properties of a convex symmetric timeinvariant third order matrix's polytope depending on a real positive parameter $r$. We apply the obtained results to the calculation of the ... -
On the stability of certain perturbed systems of differential equations and the relationship with the magnitude of the perturbation
(2010-04-16)In this work we consider a class of polytopes of third order squarematrices, studied early. We obtain a condition to guarantee Hurwitzstability of each of elements of the polytope. This condition is moresimples than one ... -

One year weekly dynamics of limnological conditions and phytoplankton in Lake Bonilla, Costa Rica
(2016)The detailed response of tropical lake phytoplankton to weather variations has been little studied, but it seems that composition varies in response to rain and wind variability over the course of the year. In order to ... -
One-side oscillation strategic approach
(2013-04-04)This paper reports an approach developed to find a good quality solution for a generalized assignment problem with application to the Dimensional Cutting Problem. The objective at the Cutting Problemis to divide different ... -
One-Sided Confidence Interval Estimation for Weibull Shape and Scale Parameters
(2012-03-02)In this paper, we consider the problem of one-sided conditional and unconditional interval estimation for the scale and shape parameters in a two-parameter Weibull model. The statistical inference is based upon the pivots ... -
Ooquistes de Cryptosporidium sp. (Apicomplexa: Cryptosporidiiadae) y presencia del C. parvum en niños de Costa Rica
(1996)From 1982 to 1987 infant and preschool Costa Rican children with acute diarrhea were studied. Cryptospo ridium (Tyzzer 1912) and other agents of diarrhea were invetigated. Criptosporydium oocysts were diagnosed in Giemsa ...
