Power Electronics: Devices, Drivers, Applications and Passive Components
Only by understanding both semiconductor device theory and high-power application can the designer be sure of selecting the correct power device for a given application. This book covers both the switches themselves and the circuitry required to make them work effectively. In this revised and updated version the author has added an entire new section on passive components - capacitors, soft magnetic materials, and resistors.
The Seventh Star of the Confederacy: Texas during the Civil War
This new anthology, edited by Kenneth W. Howell, incorporates the latest scholarly research on how Texans experienced the war. Eighteen contributors take us from the battlefront to the home front, ranging from inside the walls of a Confederate prison to inside the homes of women and children left to fend for themselves while their husbands and fathers were away on distant battlefields, and from the halls of the governor's mansion to the halls of the county commissioner's court in Colorado County.
Modernism and Democracy: Literary Culture 1900-1930
Anglo-American modernist writing and modern mass democratic states emerged at the same time, during the period of 1900-1930. Yet writers such as T. S. Eliot, W. B. Yeats, Ezra Pound, Wyndham Lewis, and Ford Madox Ford were notoriously hostile to modern democracies. They often defended, anti-democratic forms of cultural authority. Since the late 1970s, however, our understanding of modernist culture has altered as previously marginalized writers, in particular women such as Gertrude Stein, Djuna Barnes, H. D. and Mina Loy have been reassessed.
Eugène Charles Catalan made his famous conjecture – that 8 and 9 are the only two consecutive perfect powers of natural numbers – in 1844 in a letter to the editor of Crelle’s mathematical journal. One hundred and fifty-eight years later, Preda Mihailescu proved it.
Tensors, Differential Forms, and Variational Principles
Incisive, self-contained account of tensor analysis and the calculus of exterior differential forms, interaction between the concept of invariance and the calculus of variations. Emphasis is on analytical techniques, with large number of problems, from routine manipulative exercises to technically difficult assignments.
