Método para Medir Indirectamente la Velocidad de Fase en Sensores Surface Acoustic Wave
(Universidad Nacional Abierta y a Distancia, UNAD, 2015-10-22)
El sensor de temperatura Surface Acoustic Wave (SAW) ofrece amplias posibilidades para ser utilizado en ambientes hostiles. En teoría, las mediciones del SAW se pueden leer inalámbricamente sin integrar circuitos electrónicos en su estructura, permitiendo funcionalidades en mediciones a muy altas temperaturas. La literatura reporta que las variaciones de temperatura del SAW ocasionan corrimientos en su frecuencia de ...
Estimación de la huella hídrica para un cultivo de pitahaya amarilla (Selenicereus megalanthus)
(Universidad Nacional Abierta y a Distancia, UNAD, 2015-10-22)
El presente proyecto evaluó el impacto de la huella hídrica dentro del proceso productivo de pitahaya amarilla (Selenicereus megalanthus). La huella hídrica es un indicador multidimensional que cuantifica el volumen de agua utilizado para la producción de un bien. El objetivo del presente estudio es cuantificar el consumo del recurso hídrico, para concientizar a los habitantes del municipio de Palestina, Huila sobre ...
Bio-Detergent oil derivative used fryingBio-detergente derivado de aceite usado de fritura
(Universidad Nacional Abierta y a Distancia, UNAD, 2011-04-13)
Currently, the global trend towards sustainable development for environmental friendly products such as biosurfactants shows an excellent performance. Anionic surface active agents can be produced from renewable natural raw materials such as vegetable oils mainly derived from palm oil. Methyl ester sulfonate is an active component of highly biodegradable detergents, one advantage compared with detergents derived from ...
Multivariate Statistical Analysis: a Strategic Tool for Quality and Processes Control in Food IndustryAnálisis estadistico multivariado como herramienta Estratégica para el Control de procesos de calidad en la industria agroalimentaria
(Universidad Nacional Abierta y a Distancia, UNAD, 2011-04-13)
The use of multivariate statistical techniques for quality and process control in the food industry has been growing significantly since the mid-seventies, as a result of the informatics revolution which facilitated the analysis of large data sets. Unlike univariate methods of data exploration, multivariate statistics uses as a major pillar the analysis of information described by three or more variables that can be ...
Estimating the Theoretical Value for LAN Network Throughput Based Power Line Communications Technology Under the Homeplug 1.0 StandardEstimación del Valor Teórico para el Throughput en Redes LAN Basadas en Tecnología Power Line Communications Bajo el Estándar Homeplug 1.0
(Universidad Nacional Abierta y a Distancia, UNAD, 2013-06-02)
Power Line Communications (PLC) refers to a group of technologies that allow to establish communication processes under the use of the grid as a physical means of transmission. The use of the grid as a physical means of transmission of information is not a new idea. Until a few years ago, the use of PLC had been limited to the implementation of solutions of control, automation and monitoring of sensors; which did not ...
