The influence of the contact resistance interface YBCO/Au structure on transport and microwave properties arrays high-temperature bicrystal Josephson junctions embedded in a coplanar transmission line has been studied. current-voltage characteristics structures fabricated using various technologies are studied: situ ex with annealing an oxygen atmosphere. results obtained can be used to create ...

Permanent magnet linear alternators are energy converting devices that have been under research and development for years. This type of alternators have advantages of high efficiency and no need of liner motion to rotation converting, when the driving force is in linear oscillation. Such applications can be found when ocean tide, solar power, and swing motions are used for generating electric p...

This paper considers the principles of modeling, control, and simulation variable speed wind turbines (VSWTs), based on a stand-alone doubly fed induction generator (DFIG). The DFIG is used to feed three-phase highly inductive load through long cable via multi-level frequency converter (MLFC). proposed MLFC increases number voltage levels with less power electronic components as compared conven...

In the last decades, various events have shown that electromechanical oscillations are a major concern for large interconnected Alternative Current (AC) power systems. DC segmentation - method consists in turning AC grids into set of asynchronous clusters linked by Direct (DC) links is promising solution to mitigate this and other issues. However, no systematic procedure given system exists so ...

This article addresses the problem of controlling an overall wind energy conversion system (WECS) formed by a turbine connected to grid via doubly fed introduction generator (DFIG) and AC/DC/AC converter. The main control objectives are fourfold: (i) designing output feedback speed controller that makes DFIG rotate at optimal value delivered MPPT strategy, (ii) stator reactive power so as be nu...

Abstract Influenced by the continuous growth of renewable energy installation scale and increasingly prominent characteristics AC/DC hybrid structure, disturbance behavior large power grid is becoming more complex. To ensure safety grid, higher requirements are put forward for reliability, accuracy orderliness out-of-step splitting control which belonged to third line defense. Firstly, this pap...

Advanced ovarian cancer is largely incurable, but initially it is frequently confined to the i.p. space. We explored i.p. radioimmunotherapy in a mouse model of human ovarian cancer. Use of a targeted actinium-225 ((225)Ac) in vivo generator of alpha particles exploits the extreme, selective cytotoxicity of alpha particles, while providing a feasible half-life to enable delivery to tumor. (225)...
