IFEHE National Creativity Aptitude Test Research on ‘executive success’ indicates that problem solving skills is perhaps the single most important factor in the success of individuals and organizations. The willingness and ability to work hard is a necessary condition for success, it is however not a sufficient one. An organization can perform reasonably well doing things the way the best organizations do, however this can propel the organization to, at best, a number two position. The leadership position shall belong to organizations that do better than themselves.  Structure of NCAT The NCAT is open for students of engineering, management and science streams in institutes of higher education enrolled in graduate and post-graduate courses. For students in different years of their degree courses there will be separate tests in which student’s creative thinking and logical reasoning abilities will be tested. The test will be conducted in two phases. Test will be c...

Methods to improve efficiency of fourstroke, spark ignition engines at part load Abstract The  four stroke , spark ignition (SI)  engine  pressure–volume diagram ( p – V ) contains two main parts. They are the compression–combustion–expansion (high pressure loop) and the exhaust-intake (low pressure or gas exchange loop) parts. The main reason for  efficiency  decrease at part load conditions for these types of engines  is the flow restriction at the cross sectional area of the intake system by partially closing the throttle valve, which leads to increased pumping losses and to increased low pressure loop area on the  p – V  diagram. Meanwhile, the poorer combustion quality, i.e. lower combustion speed and cycle to cycle variations, additionally influence these pressure loop areas. In this study, methods for  increasing efficiency  at part load conditions and their potential for practical use are investigated. The study also incl...

the abs system - overview An ABS system consists of the following components: Some wheel speed sensors Brake calipers A hydraulic motor Some pressure release valves A quick thinking computer (or control module) which coordinates the whole process Diagram 1: Brake caliper (1) and wheel speed sensor (2) how abs works When the driver hits the brakes this pressurises a hydraulic system which causes the brake pads to squeeze against the discs which causes the car to slow down. If the ABS system detects that one wheel is slowing down more rapidly than the rest (a symptom of wheel-lock) it automatically reduces the brake pressure on this wheel by opening a pressure release valve in the hydraulic system. ABS also has the ability to build the pressure back up via the hydraulic motor. The system reacts remarkably quickly, and compared wheel speeds many times a second. ABS systems can act on just the front wheels (which do most of the braking work), or all four depending on what...
