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...
Many peer-to-peer security protocols proposed for wireless communications use one-time shared secrets for authentication purposes. This paper analyses online update mechanisms for one-time shared secrets. A new type of attack against update mechanisms, called desynchronisation attack, is introduced. This type of attack may lead to a permanent denial of service condition. A case study demonstrat...
Permanent Magnet Synchronous Motors (PMSM) have important features such as high torque, power density, acceleration, small volume, low noise and efficiency. With these features, is widely used in the industry. One of negativities that occur during operation electric motors speed fluctuations vibrations due to unbalanced loads. Unbalanced loading can be caused by character load, well poor mounti...
Speed and torque controls of permanent magnet synchronous motors are usually attained by the application of position and speed sensors. However, speed and position sensors require the additional mounting space, reduce the reliability in harsh environments and increase the cost of a motor. Therefore, many studies have been performed for the elimination of speed and position sensors. This paper i...
Polystyrene mounting medium obtainable Ltd, 20 Du The medium described by Kirkpatrick One pounc and Lendrum (1939) and named by them mountant DPX (Distrene plasticised in xylene) was (75°% one replaced by a better formula in 1941. This medium BPS (butyl phthalate plasticised styrene) has given excellent and economical service until recently. The current trouble was not due to the makers of the ...
