La detección de rostros es una de las tareas esenciales ampliamente estudiadas en el campo de la Visión por Computador. Varios autores han desarrollado diferentes técnicas para mejorar la detección de rostros en imágenes, pero estas se ven limitadas en su aplicación en videos y más si presentan baja resolución. En este estudio, proponemos un nuevo modelo para la detección de rostros en videos de baja resolución basado en la morfología de la parte superior del cuerpo de las personas y el uso de Deep Learning (CNN). Nuestros resultados muestran un promedio de 39 % de precisión en el conjunto de datos de Caviar y 32 % en el conjunto de datos de UCSP. En comparación con otras técnicas, nuestros resultados son mayores debido a que solo alcanzan el 1% de precisión.

Peru is in fact a country with important reservoirs of natural gas as Camisea and it opens potential opportunities for gas chemical development. In a mark of a higher enterprise competitiveness, in industry any time is more generalized to account with tools as support for enhanced of process and cost savings. The simulation and optimization of industrial process aided by computer is a powerful alternative. This work has as propose to make the design of a process an economical analysis with preliminary character of an integrated fertilizer complex for several plants: ammonia, nitric acid, ammonia nitrate and urea. The complex to treat the simulation in process where the transformation reactions happen in all steps of the plant, as is the case of nitric acid; it requires a great domain, not alone in the use of a powerful simulator, but a deeper knowledge of reaction kinetics and the thermo...
