Detection of volatile organic compound (VOC) vapors, which are known to have carcinogenic effects, is extremely important and necessary in many areas. In this work, the sensing properties a cobalt phthalocyanine (CoPc) thin film at six different VOC vapors (methanol, ethanol, butanol, isopropyl alcohol, acetone, ammonia) concentrations from 50 450 ppm investigated. sense, it observed that inter...

One way to optimize wastewater treatment system infrastructure, its operations, monitoring, maintenance and management is through development of smart forecasting, monitoring failure prediction systems using machine learning modeling. The aim this paper was develop a model that able predict water pump based on the asymmetrical type data obtained from sensors such as levels, capacity, current fl...

Air transportation is a very preferred type of for long-distance trips worldwide. This has made great progress with the development technology. In addition to its technological developments, passenger capacity gradually increasing due fast and secure access. contrast, mortality rate quite high in case an airplane accident, hundreds people die single accident. research aims classification severa...
