Acerca del Algoritmo de Dijkstra

Dado un grafo con etiquetas no negativas, se trata de calcular el coste del camino mı́nimo desde un vértice dado al resto (ing., single-source shortest paths). La utilidad de un procedimiento que solucione esta cuestión es clara: el caso más habitual es disponer de un grafo que represente una distribución geográfica, donde las aristas den el coste (en precio, en distancia o similares) de la cone...

Diseño de una ontología para el proceso de evaluación de las asignaturas técnico-científicas del Instituto Tecnológico de Orizaba

This paper presents the design of an ontology to support the assessment process in the technical-scientific subjects (Differential Calculus, Physical, Chemical, among others) which are taught in the firsts years of bachelor’s degree at Instituto Tecnológico de Orizaba (ITO). E-learning is one of the current strategies that facilitates the process of evaluation through the use of Web environment...

Around a Quotient Space of Bennett-Lutzer’s Space Acerca de un Espacio Cociente del Espacio de Bennett-Lutzer

Let X be the Bennett-Lutzer’s space and Y be the space obtained from X by shrinking the set of all rational numbers to a point. In his book, G.Gao claimed that the space Y is compact. In this paper, we prove that Y is neither countably compact nor Lindelöf, which shows that G.Gao’s claim is not true. Moreover, we prove that Y is strongly paracompact. As an application of this result, we obtain ...
