On the identity of Myoxanthus scandens (Orchidaceae: Pleurothallidinae), with a new species from Costa Rica
(Universidad de Costa Rica, 2010)We present and illustrate a new species of Myoxanthus from Costa Rica, closely related to M. scandens. We present descriptions and illustrations of both species. The new species, Myoxanthus sotoanum differs from M. scandens, ... -
On the phonetic realization and distribution of Costa Rican rhotics
(2007-08-14)The analysis of the Spanish data produced by speakers from the Costa Rican Central Valley evidenced that the trill has been substituted by an assibilated rhotic, while the tap also undergoes assibilation in three contexts: ... -
On the right commutativity of loop rings
(2011-02-11)Its proved that extra loops and central loops are conjugated closed, consequently they are G-loops. It is also proved that extra loops and central loops are M-loops. -
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 ... -
Ondina: La metáfora del carnaval
(2008-02-04)En este artículo se presenta una lectura del texto "Ondina" de Carmen Naranjo usando la Teoría de los Incipit, para descubrir rasgos carnavalescos. Mediante el análisis se puede observar que el cuento cumple con características ... -
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 ...
