Silicosis is a fibrotic disease of the lungs caused by inhalation, retention, and pulmonary reaction to crystalline silica. Crystalline silica exposure is widespread, and silica sand is an inexpensive and versatile component of many manufacturing processes. Its use and the incidence of silicosis are increased in industrial operations by the mechanization and the use of sandblasting, drilling, p...

Since 1850, compressed-air work has been used to prevent shafts or tunnels under construction from flooding. Until the 1980s, workers were digging in compressed-air environments. Since the introduction of tunnel boring machines (TBMs), very little digging under pressure is needed. However, the wearing out of cutter-head tools requires inspection and repair. Compressed-air workers enter the pres...

This paper presents the design of a highly efficient pneumatic motor system. The air engine is currently the most generally used device to convert potential energy of compressed air into mechanical energy. However, the efficiency of the air engines is too low to provide sufficient operating range for the vehicle. In this study, the energy contained in compressed air/pressurized hydraulic oil is...

Fault diagnosis has always been an essential aspect of control system design. This is necessary due to the growing demand for increased performance and safety of industrial systems is discussed. Support vector machine classifier is a new technique based on statistical learning theory and is designed to reduce structural bias. Support vector machine classification in many applications in v...

globally excessive consumption of hydrocarbon fuel in transport sector is a serious threat to the civilization due to paucity of fuel in future. also this growing use of vehicles for transport is contributing about 70% of total air pollution and causing environmental and ecological imbalances. thus the worldwide fast depletion of conventional energy resources and impact of emissions on environm...
