This paper presents a new single-wire autonomous current-share paralleling of current-mode-controlled dc power supplies. The proposed control scheme makes use of the nature of fast response of the inner current loop and the share bus injected signal to improve the response of the power supplies. It reduces the unbalance of current distribution during the transient state and avoids the fault ala...

The redox (Reduction-Oxidation) flow battery is one of the most promising rechargeable batteries due to its ability to average loads and output of power sources. The transient characteristics are well known as the remarkable feature of the battery. Then it can also compensate for a sudden voltage drop. The dynamics are governed by the chemical reactions, fluid flow, and electrical circuit of it...

Due to mobility, spontaneous networks composed of nodes following similar group mobility patterns are likely to overlap. Previous solutions invariantly considered overlapping as a permanent state where the networks combine to form a new network. In this paper, we propose a more realistic model where merging is either permanent or transient. Our contributions are twofold. First, we introduce a m...

In this paper the D-BMAP/G/1 queue is considered. The goal is to derive an explicit expression for the transform of the queueing delay of the nth arriving customer, based on a transient analysis. While deriving this transform, intermediate results such as an explicit expression for the transform of the probability of having an empty system at the nth departure, are also obtained. These results ...

The paper discusses the concept of entropy as applied to friction and wear. Friction and wear are classical examples of irreversible dissipative processes, and it is widely recognized that entropy generation is their important quantitative measure. On the other hand, the use of thermodynamic methods in tribology remains controversial and questions about the practical usefulness of these methods...

Electromagnetic forces on three-phase five-wire (3P5W) busbar system is investigated under three-phase shortcircuits current. The conductor busbar placed in compact galvanized steel enclosure is in the rectangular shape. Transient analysis from Opera-2D is carried out to develop the model of three-phase shortcircuits current in the system. The result of the simulation is compared with the calcu...

This paper presents time-transient polarimetric analysis for a simplified bridge model on water Surface. We extend our previous 2D time-transient analysis to 3D polarimetric scattering problem. Here the Finite-Difference Time-Domain (FDTD) method is utilized. In addition to the time-transient feature, we focus on the generating mechanism of the volume scattering component with increase of the s...

The e!ect of interconnect coupling capacitance on the transient characteristics of a CMOS logic gate strongly depends upon the signal activity. A transient analysis of CMOS logic gates driving two and three coupled resistive}capacitive interconnect lines is presented in this paper for di!erent signal combinations. Analytical expressions characterizing the output voltage and the propagation dela...

this paper undertakes the synthesis of a logic-based switching h2/h∞ state-feedback controller for continuous-time lti singular perturbation systems. our solution achieves a minimum bound on the h2 performance level, while also satisfying the h∞ performance requirements. the proposed hybrid control scheme is based on a fuzzy supervisor managing the combination of two controllers. a convex lmi-b...

a novel method to compute the stability region in power system transient stability analysis is presented. this method is based on the set analysis. the key to this method is to construct the hamilton-jacobi-isaacs (hji) partial differential equation (pde) of a nonlinear system, using which we can compute the backward reachable set by applying the level set methods. the backward reachable set of...
