The one-dimensional penetrable-square-well fluid is studied using both analytical tools and specialized Monte Carlo simulations. The model consists of a penetrable core characterized by a finite repulsive energy combined with a short-range attractive well. This is a many-body one-dimensional problem, lacking an exact analytical solution, for which the usual van Hove theorem on the absence of ph...

induction motor especially the squirrel cage type of this motor plays important role in industry. according to the application type, this motor place against various stresses that are caused failure in the motor. the most common failure is related to the stator winding. among these failures are turn-to-turn, coil-to-coil and phase to phase faults. flow the high current do to the induction resul...

Among several countermeasures suggested for thwarting differential analysis are the random ordering of operations, insertion of random operations, and random insertion of operations. This paper presents a phase-substitution technique which in combination with subsequent time-domain differential analysis is shown to be able to thwart these three countermeasures in several experiments. Unlike pre...

The spin Peierls instability describes a structural transition of a crystal due to strong magnetic interactions. Here, we demonstrate that cold Coulomb crystals of trapped ions provide an experimental test bed in which to study this complex many-body problem and to access extreme regimes where the instability is triggered by quantum fluctuations alone. We present a consistent analysis based on ...
