Book Description
The subject of this dissertation is the study of a pennanent magnet brushless motor and its feed.ing inverter in the application of an electric vehicle. The different systems of electric vehicles are reviewed in the first chapter. The solution retained is an in-wheel brushless motor with pennanent magnet NdFeB. The points focused in designing a brushless motor concem the minimisation of the harmonics and the temperature influences on the magnetic characteristics of the magnet NdFeB and, therefore, on the motor. In chapter 2, the magnets are divided in some blocks and are shifted up each other along the motor axis. Based on the static torque curve, the real dimensions of the magnets and the slots and the saturation effect have been taken into account in our study. In regular shifting, the best total shifting angle does not correspond to a tooth step. The irregular shifting is approved particularly efficient even in the case of3 magnet blocks. In the third chapter, the entire B(H) curves of NdFeB is described, for all temperatures, by means of the double variables Chebychev polynomial series. These expressions are integrated in the package Flux-Expert for determining the magnetic field of the machine (in 2D) by finite elements method. This motor is especially sensible to the temperature and the armature reaction does not change greatly the working point of magnet. The two stages DC AC-AC supply inverter allows to have a soft switching in the drive system and, therefore, a limited electromagnetic pollution in the vehicle. The behaviour of this inverter is simulated, in chapter 5, by means of a program adapted from the software A TOSEC. The simulation results show that themodulation frequency for the first stage of the inverter should be in the order of 20kHz for a good current regulation. The simulation is valid for a lspeed up to 75% of its maximum under the rated eurrent and the current control remains efficient when the current is shifted from the electromagnetic force by an angle and even with the presence of toothharmonies

Book Description
Watsuji Tetsuro's Rinrigaku (literally, the principles that allow us to live in friendly community) has been regarded as the definitive study of Japanese ethics for half a century. In Japan, ethics is the study of human being or ningen. As an ethical being, one negates individuality by abandoning one's independence from others. This selflessness is the true meaning of goodness.

Book Description
From classicism to comedy, Kubrick to the Coen Brothers, this practical and instructive guide offers a straightforward approach to film in an accessible format: a perfect read for novices and experts alike. A fresh, engaging, and beautifully illustrated volume, Talk About Cinema is the ideal companion for those looking to gain a deeper understanding of cinema today. The main genres of contemporary cinema are clearly defined and exemplified, and chapters on major dates, turning points, and "firsts" since the turn of the twentieth century allow the reader to contextualize different cinematic movements. From Postmodernism and Expressionism to Teen Movies, Westerns, and Science Fiction, all the major trends and styles of recent times are explored and provide a detailed picture of the contemporary cinematic landscape. The portraits of thirty eminent contemporary filmmakers offer valuable insight into the creative and stylistic processes of some of the greatest names in world cinema, while a chapter on twenty seminal works from the last century details those films that have proved inspirational in shaping cinema as we know it today, such as The Twilight Zone, Scarface, and Night of the Living Dead. Hundreds of screenshots and original photographs of legendary actors and directors on set and on screen provide snapshots of their glamorous world, and an easy-to-use glossary ensures that the reader is never overwhelmed by jargon. If you want to understand and discuss film-related topics, Talk About Cinema effortlessly synthesizes a wealth of pertinent facts and ideas into a fun, didactic, and readable volume.

Book Description
The Cambridge Yearbook of European Legal Studies provides a forum for the scrutiny of significant issues in EU Law, the law of the European Convention on Human Rights, and Comparative Law with a 'European' dimension, and particularly those issues which have come to the fore during the year preceding publication. The contributions appearing in the collection are commissioned by the Centre for European Legal Studies (CELS) Cambridge, a research centre in the Law Faculty of the University of Cambridge specialising in European legal issues. The papers presented are at the cutting edge of the fields which they address, and reflect the views of recognised experts drawn from the University world, legal practice, and the institutions of both the EU and its Member States. Inclusion of the comparative dimension brings a fresh perspective to the study of European law, and highlights the effects of globalisation of the law more generally, and the resulting cross fertilisation of norms and ideas that has occurred among previously sovereign and separate legal orders. The Cambridge Yearbook of European Legal Studies is an invaluable resource for those wishing to keep pace with legal developments in the fast moving world of European integration.

Book Description
Blockbusting film GOLDA starring Helen Mirren is out now 'The gripping memoir of a remarkable woman who rose to the top in a man's world. A compelling political story of courage and struggle, power and leadership, war and crisis - and the making of Israel. A classic of 20th century history' Simon Sebag Montefiore, author of JERUSALEM: THE BIOGRAPHY 'A remarkable, almost incredible personal history ... stimulating and fascinating' IRISH TIMES 'A rare and wholly unforgettable work' SATURDAY REVIEW WITH A NEW INTRODUCTION BY JULIA NEUBERGER Golda Meir was without doubt one of the most incredible women of her - and any - time. Born in 1898 in Kyiv, she was the daughter of an impoverished carpenter - and became the first (and only) female Prime Minister of Israel. Meir's earliest memory is of her father boarding up the front door in response to rumours of an imminent pogrom. The family emigrated to the US and for a while Meir lived with her sister, where she was exposed to debates on Zionism, women's suffrage, literature and socialism. She became a teacher, and after her marriage emigrated again to Palestine, settling on a kibbutz. Always politically active, she became Israel's first envoy to Moscow; was promoted to Foreign Minister and ultimately elected as Prime Minister, leader of Israel. In her autobiography she wrote: 'To me, being Jewish means and has always meant being proud to be part of a people that has maintained its distinct identity for more than 2,000 years, with all the pain and torment that has been inflicted upon it'
