This paper presents and analyzes a new dynamic element matching technique for low-harmonic distortion digitalto-analog conversion. The benefit of this technique over the prior art is a significantly reduced hardware complexity with no reduction in performance. It is particularly appropriate for applications such as direct digital synthesis (DDS) in wireless communications systems, where low har...

Presence of distributed generation (DG) in distribution systems has significant impacts on the operational characteristics of these systems, also using capacitor for reactive compensation and loss reduction is so common. Injected harmonic currents from nonlinear loads into distribution system distort all of voltages and currents and must be considered when placing the capacitor banks so that th...

We give a full classification of the multi-charge supersymmetric p-brane solutions in the massless and massive maximal supergravities in dimensions D ≥ 2 obtained from the toroidal reduction of eleven-dimensional supergravity. We derive simple universal rules for determining the fractions of supersymmetry that they preserve. By reversing the steps of dimensional reduction, the p-brane solutions...

In recent years there has been widespread use of power electronics devices and nonlinear elements in rectification and switchgear applied to various areas of power system. Power systems contain levels of harmonics which can no longer be ignored by engineers, planners, energy conservationists and economists due to the presence of non-linear loads. A simulated case study of distributed system in ...
