In this work, tests were carried out on the drying of the ají panca in a forced air solar dryer using fifteen vacuum tubes (Heat pipe), a closed cabin where the product is placed and a squirrel cage turbine that is fed by a system of two photovoltaic panels of 50 W each. The heated air is driven by the turbine from the vacuum tubes to the product in the cabin, in this work the unidimensional Fick difusion equation and numerical methods were used to determine the mass transfer coefficient 2.61 x 10- 9 ms-1 and the effective diffusivity coefficient 1.52 x 10-10 m2 s-1 and it was concluded that the drying temperature of is 55 °C is the one that best fits the results estimated by the model. The solar vacuum tube dryer is capable of maintaining an operating temperature between 50 °C to 55 °C for an irradiance of 450 to 1100 W /m2 between 9:30 am and 2:30 pm, under these conditions, in two...

In this work, tests were carried out to determine the calorific power of briquettes of alpaca and ichu manure and binder; the proportion of the mixture is 80% alpaca manure, 18% ichu, 2% lime and water in proportion to the manure. The results show the maximum temperature reached by the briquette under study is 500 ° C measured with an infrared thermometer and estimated calorific power for these briquettes 4318.18 cal / g. Due to the results obtained, the resulting briquettes can be used as an alternative and economical fuel that is also friendly to the environment. Alpaca manure at 4000 meters above sea level is not used as fertilizer for agriculture in the town of San Antonio de Chuca-Imata.

Estudia una red neural artificial inspirada en un receptor probabilístico de un modelo de distribución de afinidades del olfato. Nuestro modelo consiste en N neuronas sensoriales cuyas salidas convergen en un solo elemento de procesamiento lineal. El objetivo del sistema es modelar la discriminación de único olor de un gran número de olores de fondo dentro de un rango de concentraciones mostramos que esto es posible siempre que la concentración máxima no exceda un valor crítico.

En esta tesis desarrollamos un instrumento que mide la energía perdida por acumulación de polvo o suciedad en la superficie de arreglos fotovoltaicos, utilizamos un algoritmo que combina redes neuronales artificiales y un sistema de seguimiento de punto de máxima potencia en paneles fotovoltaicos controlado por conductancia incremental; bautizamos este enfoque como ’Neuro conductancia incremental’.El hardware del dispositivo esta compuesto de tres partes, la instrumentación, el sistema de control y un ordenador de placa única. La instrumentación fue construida al rededor de un micro controlador que gestiona una memoria de configuración eeprom de 1MB, una memoria de datos SD de 1GB, un sistema de gestión de energía debaterías de litio, una interface de comunicación USART-USB , un reloj de tiempo real y un convertidor analógico digital de 24 bit con cuatro canales diferenci...
