Análisis de transitorios de sobretensión en redes de baja tensión

Sensitivity analysis of a power system against overvoltage was performed. The analysis took into account the origin of the overvoltage, the grounding resistance magnitude and overvoltage injection point. The IEEE 13 bus test feeder system was implemented in EMTP-ATP and lightning and switching overvoltages were applied. Three cases were evaluated: the first one, applying lightning overvoltage a...

Optimización en ubicación de estaciones base de baja potencia LTE

This paper develops an Integer Linear Programming Model (ILPM) to find the optimal emplacement of low power base stations in order to resolve traffic congestion problem in hotspots within a LTE macro cell. A cost function represents the objective function inside the ILPM and it is restricted to the most important technical parameters in the planning networks process of design: user demand, cove...

Hacia el Uso de la Información Sintáctica y Semántica en los Sistema de Búsqueda de Respuesta

Current question answering systems typically combine methods based in information retrieval and information extraction. Such methods leverage the speed of the resulting algorithms and the presence of information redundancy, but few systems use methods based on linguistic information beyond the word level. In this paper we present a study of the impact of the syntactic and semantic information i...

GENETIC DIVERGENCE IN CHICKPEA (Cicer arietinum L.)

Genetic diversity of 27 chickpea genotypes was studied through Mahalanobis D and Principal Component analysis. The genotypes under study fall into five clusters. The cluster II contained the highest number of genotypes (11) and Cluster I contained the lowest. Cluster I produced the highest mean value for number of pods per plant. The inter cluster distances were much higher than the intra clust...
