In order to reduce the temperature in marine engine cabin, improve working environment of staff and meet economy emission requirements, cooling system was experimentally investigated present study. this regard, water air-cooling schemes were studied main indicators including torque, smoke-emission, exhaust analyzed. The obtained results indicate that highest torque can be from turbine case pipe...

the goal of this research is the derivation of method for evaluation of efficiency improvement potential for district heating systems with focus on variable speed centrifugal pump. the effectiveness of the usage of the proportional pressure control is compared with the constant pressure control. this is why, energy calculation analyses have been realized for variable speed centrifugal pumps, an...

Regarding the power, the efficiency and the discharge questions of the low-speed diesel engine, this article studied emphatically the Miller cycle, the analysis technology for the air intake system, and the matching technology for the intake and the exhaust. On the foundation of the twin inlet structure the paper analyzed the intake swirl control area and its influence to the gas charging effic...

Linear regression models are often used to represent the cost and effectiveness of medical treatment. The covariates used may include sociodemographic variables, such as age, gender or race; clinical variables, such as initial health status, years of treatment or the existence of concomitant illnesses; and a binary variable indicating the treatment received. However, most studies estimate only ...
