Adsorción de hidrocarburos y óxidos de carbono en materiales silicoaluminados microporosos

Dinámica de la penetración de tecnologías alternativas para vehículos automotores y su impacto en las concentraciones de carbono atmosférico

Estructura, Biomasa a\'erea y carbono almacenado en los bosques del Sur y Noroccidente de c\'ordoba

We estimated the aerial biomass and stored carbon in twelve types of forests in the department of Córdoba with annual rain fall ranging from 3000 mm (super humid climates) to 1300 mm (semihumid climate). Biomass was estimated based on structural aspects of the vegetation (diameter at breast height, total height, and wood specific weight). We tested nine allometric equations for tropical forests...

Comparación y combinación de los sistemas de traducción automática basados en n-gramas y en sintaxis

In this paper we shall compare two approaches to machine translation: the Syntax Augmented Machine Translation system (SAMT), which is a syntaxdriven translation system, underlain by phrase-based model, and the n-gram-based Statistical Machine Translation (SMT), in which a translation process is based on statistical modeling of the bilingual context. We provide a step-by-step comparison of the ...

Duplicité de l’urètre de type IIA2 en “Y”

Urethral duplications are extremely rare congenital malformations. The most used classification is that of Effmann and Lebowitz, describing 6 types of urethral duplications. The under type IIA2-Y is one of the most rare duplications corresponding to duplicated urethra originating from the bladder neck and extending toward the ectopic perineal or anal insertion. We here report the case of a 32 y...

Mejora de Contraste y Compensación en Cambios de la Iluminación

In this paper a contrast operator built by means of two primitives involving Weber’s Law is presented. The proposed contrast mapping has two objectives, in the first place the contrast enhancement and in the second, the normalization of the processed image. The contrast enhancement is based on the image background detection; this parameter is computed through the analysis of the regional minimu...
