Dowding & Churchill: The Dark Side of the Battle of Britain

為了解決LED 規格的問題，作者Dixon, Jack 這樣論述：

Air Chief Marshal Sir Hugh - later Lord - Dowding was one of the greatest Englishmen of the 20th century. He created Fighter Command with its unique early warning system (radar) from nothing in 1936 to the efficient defensive force it became in 1940. In consequence Fighter Command was the only ar

m that was properly prepared for battle when war was declared against Germany. Hugh Dowding led Fighter Command in the Battle of Britain, and was victorious. The campaign, although a series of defensive engagements, was one of the decisive battles of Western Civilization. The strategic importance of

the Battle of Britain was recognized at the time, yet, the moment it was won Dowding was summarily relieved of his command and shuffled into retirement without recognition, reward or promotion. This book reveals that this was the result of a shabby conspiracy by fellow officers. The Air Ministry pu

blished a brief account of the Battle in March 1941 and in it there was no mention of Dowding. Churchill was furiously indignant. But in November 1940 he had acquiesced in Dowding's removal. Why? And what are the factors that led to Dowding's dismissal in the first place? In this thought-provoking a

nd authoritative book Jack Dixon answers these questions and explains Dowding's true greatness

Isis: The Killing Caliphate: the Ideology of Terror

為了解決LED 規格的問題，作者Catherwood, Christopher 這樣論述：

Every war has its cause and every conflict its context, none more so than the centuries-old ideological battle between Christian and Muslim theology. The concept of holy war is almost as old as the religions themselves, with Christian crusades and Muslim invasions of North Africa, Asia and Europe

. From 630 Islamic armies were engaged in massive imperialist conquest that created one of the most successful empires in history, stretching from the borders of Hindu India in the East to Christian Spain in the West. Until the failed attempt to capture Vienna in 1683 the Islamic armies mounted an a

lmost continuous assault on Europe. Not until 1913 would some parts of Europe be free from Muslim rule. The defeat of the Ottoman Empire in 1918 led to the secularisation of Turkey and the Turkish leader Kemal Ataturk's abolition of the Caliphate in 1924. That act ended the Islamic empire, with the

Christian West, in the form of Britain and France, in control of large areas of the realm of Islam - the Middle East we know today being largely shaped by Winston Churchill. Conflict was inevitable. The tragic events of 9/11 were the result of a long process within Islam and the Islamic world, rathe

r than the beginning of it - and now we have Isis and an attempt to revive the Caliphate. No-one knows how it will end. The author, who has written extensively on the subject of the continuous struggle between Christianity and Islam, investigates the key events throughout history that led to the est

ablishment of the state of Israel, the Islamic rage of the twentieth century, Al Qaeda, the conflict between Sunni and Shia, and the rise of Isis. ISIS: The Killing Caliphate explains the motives behind holy war and how the fighting in the Middle East is merely the latest manifestation of the ageles

s battle between theologies - war in the name of God.

全向輪型車避障設計及實踐

為了解決LED 規格的問題，作者羅裕彰 這樣論述：

本論文主要研究全向輪形機械人之路徑規劃運動控制及相關實踐。路徑規劃會預先導出全向輪形機械人避障會使用到路徑的數學式，再使用MATLAB模擬路徑。控制方式則會以PID控制為主導，PID控制相對的好處是：簡單的、容易對控制器作出調整、提供良好的穩定性，快速響應和相對穩定。本論文中亦採用全向輪這種特殊的輪子，利用其輪子的特殊設計，達到不需要轉向，仍然可以向任何方向自由移動。
