Paul Detrick The NEO PI-R is one of a group of closely-related objective assessment instruments (NEO Inventories) designed to measure the Five-Factor Model (FFM) of personality (Digman, 1990; McCrae & John, 1992). The FFM has received widespread acceptance as a valid descriptor of normal personality (Mount & Barrick, 1998), as well as an organizing framework for the prediction of job performanc...

nowadays, cad/cam simulation is considered as a strong tool to estimate performance of various systems and to reduce costs and testing time. in this study, we used gt-power software to model the performance of an si engine. the results indicate that the engine power drops significantly as altitude increases. to compensate power loss, the engine is equiped with a turbocharger system. the proper ...

in order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems. in this paper, during an engine design and development process, a network analysis of the engine lubrication system is described in detail. two elements have been added to the lubrication circuit in the modified engine. these elements are hydraulic lifters and an anti-drai...

Nowadays, the highly competitive automotive business industry requires manufacturers to pay more attention to passenger comfort and riding quality. This has forced designers to direct their attention to the development of high quality engine mounting devices, with traditional physical prototyping and testing being gradually replaced by virtual prototyping and numerical simulations. Following th...

in this paper, the enhancement of vehicle stability and handling is investigated by control of the active geometry suspension system (ags). this system could be changed through control of suspension mounting point’s position in the perpendicular direction to wishbone therefore the dynamic is alternative and characteristics need to change. for this purpose, suitable controller needs to change mo...
