The main objective of this project is to make the total input current drawn from the three phase ac main as sinusoidal, by compensating reactive power and low order harmonics generated by the three phase non-linear loads. The synchronous d-q-o reference frame algorithm is also been implemented to recognize and extract harmonic distortions. The outcome will be Total Harmonic Distortion free supply mains. such that the input current will be compensated.The filter is used to counter the effects of harmonics on three-phase power distribution systems and thus improve the system power quality. Technologies Used: MATLAB, Micro Controller, KIEL.

Seminar paper from the year 2012 in the subject Politics - International Politics - Region: USA, grade: 1,3, Christian-Albrechts-University of Kiel, language: English, abstract: The president of the United States is often mentioned in the media as the most powerful man in the world (Forbes 2012). But how far does his power reach in foreign affairs? Has he, as the commander in chief, the inherent power "to do anything, anywhere, that can be done with an army or navy" (Youngstown Sheet & Tube Co. v. Sawyer, 1952: p. 642)? Can the Supreme Court control the president when he is acting with this executive powers and his authority as commander in chief? Did the president had the power to order the Korean War, the Vietnam War, the Congo rescue operation, the bay of pigs invasion, the intervention in the Dominican Republic or the engagement in the Cuban missile crisis without approval by Congress? Can the U.S. government detain foreign citizens indefinite at Guantanamo Bay and declare them as enemy combatants, without due process and suspend the writ of habeas corpus? Is the National Security Agency authorized to intercept international communication reputedly linked to al Qaeda or other terrorist organizations?This paper argues that there is no well-recognized inherent power giving the president the possibility to act in foreign affairs without judicial control and congressional authorization, even though there is a long debate about this issue.

The enlarged new edition of this textbook provides a comprehensive introduction to the basic processes in plasmas and demonstrates that the same fundamental concepts describe cold gas-discharge plasmas, space plasmas, and hot fusion plasmas. Starting from particle drifts in magnetic fields, the principles of magnetic confinement fusion are explained and compared with laser fusion. Collective processes are discussed in terms of plasma waves and instabilities. The concepts of plasma description by magnetohydrodynamics, kinetic theory, and particle simulation are stepwise introduced. Space charge effects in sheath regions, double layers and plasma diodes are given the necessary attention. The novel fundamental mechanisms of dusty plasmas are explored and integrated into the framework of conventional plasmas. The book concludes with a concise description of modern plasma discharges.Written by an internationally renowned researcher in experimental plasma physics, the text keeps the mathematical apparatus simple and emphasizes the underlying concepts. The guidelines of plasma physics are illustrated by a host of practical examples, preferentially from plasma diagnostics. There, Langmuir probe methods, laser interferometry, ionospheric sounding, Faraday rotation, and diagnostics of dusty plasmas are discussed. Though primarily addressing students in plasma physics, the book is easily accessible for researchers in neighboring disciplines, such as space science, astrophysics, material science, applied physics, and electrical engineering.This second edition has been thoroughly revised and contains substantially enlarged chapters on plasma diagnostics, dusty plasmas and plasma discharges. Probe techniques have been rearranged into basic theory and a host of practical examples for probe techniques in dc, rf, and space plasmas. New topics in dusty plasmas, such as plasma crystals, Yukawa balls, phase transitions and attractive forces have been adopted. The chapter on plasma discharges now contains a new section on conventional and high-power impulse magnetron sputtering. The recently discovered electrical asymmetry effect in capacitive rf-discharges is described.The text is based on an introductory course to plasma physics and advanced courses in plasma diagnostics, dusty plasmas, and plasma waves, which the author has taught at Kiel University for three decades. The pedagogical approach combines detailed explanations, a large number of illustrative figures, short summaries of the basics at the end of each chapter, and a selection of problems with detailed solutions.

ggf. zzgl. Versand

Wasser ist eine globale Ressource für heutige Gesellschaften - Wasser war eine globale Ressource vormoderner Gesellschaften. Die manigfaltigen unterschiedlicher Wassersysteme für Prozesse der Urbanisierung und das urbane Leben in der Antike und dem Mittelalter ist bislang kaum erforscht. Die zahlreichen Beiträge dieses Bandes fragen nach der grundlegenden kulturellen Bedeutung von Wasser ( bzw. power of water) in der Stadt und Wasser für die Stadt aus unterschiedlichen Perspektiven. Symbolische, ästhetische oder kultische Aspekte werden ebenso thematisiert wie die Rolle von Wasser in Politik, Gesellschaft oder Wirtschaft und dem alltäglichen Handeln, aber auch in Stadtplanungsprozessen oder städtischen Teilräumen. Nicht zuletzt stellen die Gefahren von verschmutzten Wasser oder Überschwemmungen die städtische Gesellschaft vor Herausforderungen. Die Beiträge diesen Band lenken den Blick auf die komplexen und vielfältigen Beziehungen zwischen Wasser und Menschen. Das Sammelwerk präsentiert die Ergebnisse einer internationalen Tagung in Kiel 2018. Es wendet sich gleichermaßen an Leser aus den altertumskundlichen wie mediävistischen Fächern und darüberhinaus an alle Interessierten, die sich über die Vielfalt von Wassersystemen im Stadtraum der Antike und des Mittelalters informieren möchten.

ggf. zzgl. Versand

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Otto Hahn was one of only four nuclear-powered cargo vessels so far built. Planning of a German-built trade and research vessel to test the feasibility of nuclear power in civil service began in 1960, and Otto Hahn's keel was laid down in 1963 by Howaldtswerke Deutsche Werft AG of Kiel. She was launched in 1964 and named in honour of Otto Hahn, the German chemist and Nobel prizewinner, who was credited with the discovery of nuclear fission of uranium in 1938. The first captain of the Otto Hahn was Heinrich Lehmann-Willenbrock, a famous German U-Boat ace of World War II. In 1968, the ship's 38-megawatt nuclear reactor was taken critical and sea trials began. In October of that year, NS Otto Hahn was certified for commercial freight transport and research.
