Innovative Fiber Optic/Thin Film Photovoltaic Systems: Adequately Distributing Daylight While Harvesting Energy

On any given year, Las Vegas will be exposed to an average of 85% sunlight during typical daylight hours, while averaging seven peak hours a day. That alone makes Las Vegas a prime candidate for renewable solar energy systems (Solar Direct, 2016). By implementing fiber optics into office buildings in conjunction with thin-film photovoltaics, interior spaces have the potential to be adequately illuminated while simultaneously harvesting electricity. The study will be conducted through analysis and experimental field research with the intent of generating physical data, demonstrating that a hybrid fiber optic - photovoltaic system can at minimum match recommended foot-candle values and reduce a building’s electricity demand. Supplementary information on United States energy generation and consumption of fuels and the experimental data from this study are cataloged under appendix 1 and 2

Human capability evaluation approach for cybersecurity in critical industrial infrastructure

Every organization is as frail as its frailest human link in the cyber security of Industry Control System (ICS), which is without predisposition to conceivable technological solutions for enforcing security. Noticeably, human-involved systems are becoming more chaotic, and gravely under attacks due to irregular actions or inactions of human entities in the constituent chain. Many industrial cyber-attacks have successfully defeated technological security solutions through preying on human weaknesses in knowledge and skills, and manipulating insiders within organizations into unsuspectingly delivering entry and access to sensitive industrial assets. In order to help enterprises assess the level of employees’ cyber security awareness and responsiveness, and enhance ICS Cyber security knowledge and skills for ICS protection, a Workforce Cyber Security Capability evaluation model is presented, and theoretically validated. A capability evaluation will allow industries to have a better understanding of the potential state of consciousness, readiness and diagnostic abilities of the industries; thus improve the prevention, detection, and response to any cyber-specific incidents

Evaluación de variables para la producción de metil ésteres a partir de aceite de semilla de algodón asistido por ultrasonido

El uso de la radiación ultrasónica como una nueva herramienta de mezcla, más eficiente en la producción de biodiesel brinda una alternativa a los métodos convencionales de producción. La energía del ultrasonido mejora la transferencia de masa entre los reactivos no miscibles a través de la cavitación ultrasónica lo que genera no solo una mayor eficiencia en la reacción y ahorro de tiempo, sino que además puede ser económicamente viable, ya que requiere poca cantidad de catalizador y sólo entre un tercio y la mitad de la energía que se consume por agitación mecánica debido a que maximiza el área superficial de la interfase entre los reactivosno miscibles y con consumos de energía más bajos que la de los reactores agitados. en este trabajo se evalúan los resultados de reacciones asistidas por ultrasonido utili- zando un plan de trabajo donde se varían los parámetros tiempo de reacción, relación molar aceite/alcohol, cantidad de catalizador y temperatura; manteniendo constantes los parámetros de frecuenta y potencia del baño de ultrasonido. Se lograron conversiones superiores al 90% de triglicéridos a metil ésteres
