Electrons and Phonons in Semiconductor Multilayers
ISBN: 9781107424579 / Angielski / Miękka / 422 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Advances in nanotechnology have generated semiconductor structures that are only a few molecular layers thick, and this has important consequences for the physics of electrons and phonons in such structures. This book describes in detail how confinement of electrons and phonons in quantum wells and wires affects the physical properties of the semiconductor. This second edition contains four new chapters on spin relaxation, based on recent theoretical research; the hexagonal wurtzite lattice; nitride structures, whose novel properties stem from their spontaneous electric polarization; and...

Exploratory Experiments: Ampère, Faraday, and the Origins of Electrodynamics
ISBN: 9780822944508 / Angielski / Twarda / 544 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The nineteenth century was a formative period for electromagnetism and electrodynamics. Hans Christian Orsted's groundbreaking discovery of the interaction between electricity and magnetism in 1820 inspired a wave of research, led to the science of electrodynamics, and resulted in the development of electromagnetic theory. Remarkably, in response, Andre-Marie Ampere and Michael Faraday developed two incompatible, competing theories. Although their approaches and conceptual frameworks were fundamentally different, together their work launched a technological revolution--laying the foundation...

Distribution Systems with Distributed Generation
ISBN: 9783659430695 / Angielski / Miękka / 172 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. With the penetration of Distributed Generation in Electric Distribution Systems, recloser-fuse coordination problems appear due to the unplanned DG fault currents. In this book, an integrated novel strategy is proposed to solve such problems. The proposed strategy is based on two main steps; the first is to assess the coordination status at fault conditions and decide whether coordination holds or is lost. The second step provides three different solutions to decrease the cases where coordination is lost to avoid as much as possible doing major changes in the existing protection scheme. The...

Modélisation vectorielle multimachines des systèmes polyphasés
ISBN: 9786131543562 / Francuski / Miękka / 200 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Les machines polyphasees offrent de nombreux avantages par rapport a leurs homologues triphasees. Neanmoins, leur alimentation par onduleur de tension a montre qu'il fallait apporter un soin particulier a leur modelisation. Dans cet ouvrage nous presentons un outil de modelisation des systemes polyphases, quel que soit le nombre de phases, base sur une Representation Energetique Macroscopique (REM) associee au formalisme vectoriel (extension de la theorie des vecteurs d'espace). Le formalisme, d'abord applique a la modelisation des machines polyphasees synchrones a aimants permanents, montre...

Vieillissement électrique de la résine époxyde
ISBN: 9786131541544 / Francuski / Miękka / 192 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Les resines epoxydes sont employees depuis longtemps comme isolation des systemes electriques. Elles sont generalement formulees avec une dispersion des micro- charges pour ameliorer les proprietes thermiques et mecaniques. Toutefois, des problemes demeurent quant a l'influence possible de ces charges sur le comportement electrique, particulierement sur le vieillissement a long terme sous differentes contraintes. L'objectif est de sonder l'activite electrique des defauts potentiels en analysant les signaux optiques sous contrainte alternative (jusqu'a 9 kV). L'obstacle majeur de ce travail a...

Wound Rotor Induction Generator Scalar Modeling and Control
ISBN: 9783659505904 / Angielski / Miękka / 180 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In the field of electrical power generation, the wind energy is one of the important sources of renewable energy. The main problem with this type of energy is the variable nature of the wind speed. The wound rotor induction generator is used to handle this speed variations by adequate voltage injections in the rotor circuit to maintain the stator voltage and frequency constant irrespective to speed or load variations. This book deals with the analysis, steady state modeling, and control of the wound rotor induction generator that can be used in wind energy applications. Moreover the linear...

Optimal Capacity Planning of Distributed Generators
ISBN: 9783659593734 / Angielski / Miękka / 160 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In this book, a method based on a sensitivity analysis and quadratic curve-fitting technique for power loss reduction in a low-voltage distribution area is proposed. For determining the optimum generation capacity of multiple DG units, a new methodology based on an unbalanced multi-phase optimal power flow (UM-OPF) is also presented. During the formulation of the UM-OPF, an optimisation algorithm is developed in Matlab and the unbalanced multi-phase power flow is solved using the Electric Power Research Institute's (EPRI) software OpenDSS. To ensure a global minimum loss profile, adaptive...
