Gas turbines are currently a popular power generation technology in countries with access to natural gas resources. However they are very complex systems the operation of which at peak performance is challenging. This paper proposes the use of a hybrid approach based on an Adaptive Neuro-Fuzzy Inference System (ANFIS) for the control of the speed and the exhaust temperature of a gas turbine. Th...

Nowadays, ceramic exhaust gas sensors are installed in quantities of millions in automotive exhaust gas systems. Almost any automobile being powered by a gasoline combustion engine is equipped with at least one zirconia exhaust gas oxygen sensor (l probe) for detection of the air-to-fuel ratio l. The first part of this short overview focuses on potentiometric as well as on amperometric zirconia...

Biofilters are an effective and economically feasible technique for mitigating odor and other gaseous emissions from livestock production systems. They consist of a media containing a biofilm, where microorganisms break down compounds in livestock building exhaust air into energy and nutrients for growth and reproduction. In addition to capital costs, continuous filtering of exhaust air from me...
