In this paper, an analytical solution for computing the linear plastic stresses and critical pressure in a FGM hollow cylinder under the internal pressure due to non-Axisymmetric Loads is developed. It has been assumed that the modulus of elasticity was varying through thickness of the FGM material according to a power law relationship. The Poisson's ratio was considered constant throughout the...

drug-in-adhesive transdermal drug delivery systems  )tddss) containing stimulants, termed as energetic substances, such as caffeine and pantothenic acid, were studied. caffeine is a white crystalline substance and a stimulant to central nervous system. in humans, caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness. pantothenic acid, al...

In internal combustion engines, exhaust valve and its seat gain considerable temperature as the hot gases exit through them. So, the rate of heat transfer should be under control. In this study, the contact heat transfer coefficient has been estimated. An experimental study on an Air-Cooled internal combustion engine cylinder head has been considered. Using the measured temperatures of sensors ...

We presents a new necessary and sufficient condition for the blind separation of sources having non-zero kurtosis, from their linear mixtures. It is shown here that a new blind separation criterion based on both odd ( ) and even ( ) functions, presents desirable solutions, provided that all source signals have negative kurtosis (sub-Gaussian) or have positive kurtosis (super-Gaussian). Based on...

_______________________________________________________________________________ Abstract— This paper proposes a rigorous stability criterion for the 2 order digital phase locked loop (DPLL), with a charge pump phase frequency detector (CP-PFD) component. The Stability boundary is determined using piecewise linear methods to model the non-linear nature of the CP-PFD component block. It calculate...

In two experiments we examined which cognitive processes people use in a non-linear multiple cue judgment task, proposing that people are not able to use explicit cue abstraction when judging objects with a non-linear structure between the cues of the objects and the criterion and therefore they are forced to use exemplar-based processes. Consistent with the results reveal strong exemplar effec...
