Optimization is ubiquitous in power system engineering. Drawing on powerful, modern tools from convex optimization, this rigorous exposition introduces essential techniques for formulating linear, second-order cone, and semidefinite programming approximations to the canonical optimal power flow problem, which lies at the heart of many different power system optimizations. Convex models in each optimization class are then developed in parallel for a variety of practical applications like unit commitment, generation and transmission planning, and nodal pricing. Presenting classical approximations and modern convex relaxations side-by-side, and a selection of problems and worked examples, this is an invaluable resource for students and researchers from industry and academia in power systems, optimization, and control.

This practical resource introduces readers to the design of field programmable gate array systems (FPGAs). Techniques and principles that can be applied by the engineer to understand challenges before starting a project are presented. The book provides a framework from which to work and approach development of embedded systems that will give readers a better understanding of the issues at hand and can develop solution which presents lower technical and programmatic risk and a faster time to market. Programmatic and system considerations are introduced, providing an overview of the engineering life cycle when developing an electronic solution from concept to completion. Hardware design architecture is discussed to help develop an architecture to meet the requirements placed upon it, and the trade-offs required to achieve the budget. The FPGA development lifecycle and the inputs and outputs from each stage, including design, test benches, synthesis, mapping, place and route and power estimation, are also presented. Finally, the importance of reliability, why it needs to be considered, the current standards that exist, and the impact of not considering this is explained. Written by experts in the field, this is the first book by "engineers in the trenches" that presents FPGA design on a practical level.

When Baby Brown Bear arrives, all alone and very frightened, at City Zoo, Mama Polar Bear scoops him into her arms and promises to be his mother. Despite the grumblings of the other zoo animals, Baby Brown Bear learns family is family, no matter the differences, and all bears need love.

What's the best way to learn about the different periods in theatre history? By example, of course In "A Brief History of Theatre," the audience is taken on a tour of theatre history by presenting (almost) the same story in three styles: Ancient Greek, Elizabethan, and Modern Musical. The fourth wall is irreparably broken as two Announcers introduce and comment on three separate yet inseparable plays: "Four Against a Serpent," "All's Well That's Dressed in Armor," and "Sammy & Kate." Designed for flexible casting, the show has twenty-three speaking roles (not counting the Greek Chorus) and room for plenty of extras, but can be performed with as few as nine actors of any gender.
