Pointwise matching (PM) and integral projection (IP) methods are two widely used techniques to extend the classical weak formulations to include non-conforming grids. We present spectral element formulations on polynomial (p-type) and geometric (h-type) non-conforming grids using both the PM (also known as the Constrained Approximation) and IP (also known as the Mortar Element) methods. We syst...

axial flux permanent magnet (afpm) machines are attractive candidates for electric vehicles (evs) applications due to their axial compact structure, high efficiency, high power and torque density. this paper presents general design characteristics of afpm machines. moreover, torque density of the machine which is selected as main objective function, is enhanced by using genetic algorithm (ga) a...

This paper presents the design, fabrication and performance of a three-stage 155GHz monolithic low noise amplifier (LNA) using 0.1 -pm pseudomorphic (PM) InAIAs/InGaAs/InP HEMT technology. This amplifier exhibits a measured small signal gain of 12 dB at 155 GHz, and more than 10 dB gain from 151 to 156 GHz. When this amplifier is biased for low noise figure, a noise figure of 5.1 dB with associ...

This paper presents a preventive maintenance (PM) policy for leased equipment over a finite lease period L. Maintenance is entrusted to the lessor. The purpose is to determine the PM period T minimizing the expected total cost over the lease period in a context where repairs and PM actions are imperfect and have non-negligible durations. The leased equipment is periodically subjected to imperfe...

This is the first study to demonstrate that colour transformations in the volume of a photochromic material (PM) are induced at the intersections of two control light channels, one controlling PM colouration and the other controlling decolouration. Thus, PM colouration is induced by position selectivity, and therefore, a dynamic volumetric display may be realised using these two control lights....

have infinitely many solutions. If the well known hypothesis about prime twins is true, that is, if the equation pn+i—pn — 2 has infinitely many solutions, (1) and (2) of course are trivially satisfied. The first inequality of (2) is inserted only for the sake of completeness. I t follows from the well known fact that lim sup (pn+i—pn) = °° (since n\+2, n\+3, • • • , » ! + » are all composite)....

A 3D ‘atomistic’ simulation technique to study random dopant induced threshold voltage lowering and fluctuations in sub 0.1 pm MOSFlETs is presented. It allows statistical analysis of random impurity effects down to the individual impurity level. Efficient algorithms based on a single solution of Poisson’s equation, followed by the solution of a simplified current continuity equation are used i...

Recent studies have suggested that medial (medBA10) and lateral (latBA10) portions of the Brodmann area 10 subserve respectively stimulus-oriented (SO) and stimulus-independent (SI) attending during prospective memory (PM) tasks. We investigated this dissociation by manipulating the saliency (SO) and the memory load (SI) of PM cues. Sixteen healthy subjects participated to a functional imaging ...
