Electromagnetic acoustic transducer (EMAT) is a kind of non-contact ultrasonic transducer, and during its operation, no liquid coupling is required. Despite this advantage, EMAT has low transduction efficiency and its performance depends on the tested object, thus further research of its complex multiphysics transduction mechanism involving both electromagnetic and elastodynamic phenomena is paramount...
Management of multi-echelon with transshipments is an effective approach to improve support effectiveness. A common assumption in early papers is that transshipments are allowed between all locations. However, this configuration may not be the best choice in many fields. Focusing on the problem, a system where transshipments are allowed only in one direction is provided. Such policies may be of interest...
Low-power circuits are especially sensitive to the increasing levels of process variability and uncertainty. In this paper we study the problem of leakage power minimization through dual Vth design techniques in the presence of significant Vth variation. For the first time we consider the optimal selection of Vth under a statistical model of threshold variation. Probabilistic analytical models are...
