Complete with equations, illustrations, and tables, this book covers the basic theory of electric power transformers, its application to transformer designs, and their application in utility and industrial power systems. The author presents the principles of the two-winding transformer and its connection to polyphase systems, the origins of transformer losses, autotransformers, and three-winding transformers and compares different types of transformer coil and coil construction. He describ...

A watched clock never movesThe church clock in this unassuming South Midlands village has stopped, and for good reason. The old man who wound it up lay lead in the tower, decapitated.Dr. Jackson (Jacko), a local historian, becomes drawn in to the police enquiry, but not before there are more unexplained deaths, including one at the home of a local MP. Then the vicar vanishes into thin air.Is there a common thread? Why are the Intelligence Services i...

Science and medicine have long been close partners, and this is particularly true in radiology where the availability of imaging techniques is central to diagnosis. An understanding of the science underlying an imaging process enables the development of new or improved techniques, comprehension of the imaging limitations and even the creation of a research portfolio. This volume is intended as an education resource to help study and pass the necessary exams in physics required for medical ...

The TRACE (Toronto annual Canadian econometric) model is an annual, non-linear econometric model of the Canadian economy designed primarily to forecast the statistics which appear in the principal tables of the Canadian National Income and Expenditure Accounts. TRACE is the first Canadian econometric model from which a published ex ante forecast has been made. In this book the authors describe the model and a high-speed computer. They show how the effects of alternative combinatio...

An innovative roadmap to facing our past and present selvesHonest, aching, and intimate, self-elegies are unique poems focusing on loss rather than death, mourning versions of the self that are forgotten or that never existed. Within their lyrical frame, multiple selves can coexist—wise and naïve, angry and resigned—along with multiple timelines, each possible path stemming from one small choice that both creates new selves and negates potential selves. Giving voi...
