Abstract. This paper deals with the numerical reconstruction of the plasma current density in a Tokamak and of its equilibrium. The problem consists in the identification of a non-linear source in the 2D Grad-Shafranov equation, which governs the axisymmetric equilibrium of a plasma in a Tokamak. The experimental measurements that enable this identification are the magnetics on the vacuum vesse...

Multiphase voltage regulator modules (VRMs) for microprocessor power delivery with coupled output inductors are discussed. Strong coupling is shown to be feasible and effective at reducing ripple if the correct magnetic topology is used. For more than two phases, this can be a “ladder” core with windings around each rung. Typical ripple reduction is better than a factor of six with no effect on...

Nowadays, the objects for magnetics are spreading to various fields. Under those circumstance, the requirements to theoretical analysis increase, i.e. a simple modeling, numerical prediction, etc. Besides, the requests such as materials predictions based on the data base analysis called “materials informatics” or “material genome” become strong, too. Generally, from a viewpoint of magnetics, it...

We define and analyze the ACATS declustering scheme for use with the classic Level 5 as well as MDS RAIDs. ACATS provides a paradigm for distributed sparing and checking as well. Using Markov models we calculate the reliability of classic Level 5 as well as MDS RAIDs both with and without ACATS. Our results demonstrate, for fixed hardware configurations, tradeoffs between performance and reliab...

This thesis describes an efficient numerical simulation technique of magnetoquasistatic electromagnetic fields for planar induction heating applications. The technique is based on a volume-element discretization, integral formulation of Maxwell’s equations, and uses the multilayer Green’s function to avoid volumetric meshing of the heated material. The technique demonstrates two orders of magni...
