Since their emergence, finite element methods have taken a place as one of the most versatile and powerful methodologies for the approximate numerical solution of Partial Differential Equations. These methods are used in incompressible fluid flow, heat, transfer, and other problems. This book provides researchers and practitioners with a concise guide to the theory and practice of least-square finite element methods, their strengths and weaknesses, established successes, and open problems.
The author and her siblings grew up in a large home in a neighborhood where country clubs and maids were the norm. What would her friends think if they knew what life with her father was really like? As a young girl, Suzy hid these stories from her friends: the frustration and anger, the undiagnosed mental illness, the crazy stories involving dogs, high heels, and homelessness.Vacuum in Squares recounts Suzy's life with a father who appeared normal and high functioning, yet behind closed doors was combative, abusive, and unloving. Sometimes sad, sometimes hilarious, this is a heartfelt account of her never-ending search for her father's love and her refusal to fall victim to a man who was hell-bent on destroying his family.

Image orthicons with structured targets were tested using a new cycled test set which separates the functions of exposure and read-out by a selected time interval. Resolution of image orthicons, when cycled in a manner corresponding to slow scan read-out, has exceeded 50 percent sine-wave response at 500 TV lines/inch. Possible means of increasing resolution toward the contract objective of 1500 TV lines/inch are discussed. Electron gun resolution, measured at high velocity, was nearly doubled during the year. Improvement was achieved by smoothing the mixed carbonate cathode coating. The procedures used to process targets are explained in detail. (Author).
This book is a gentle introduction for all those wishing to learn about modern views of the cosmos. Our universe originated in a great explosion – the big bang. For nearly a century cosmologists have studied the aftermath of this explosion: how the universe expanded and cooled down, and how galaxies were gradually assembled by gravity. The nature of the bang itself has come into focus only relatively recently. It is the subject of the theory of cosmic inflation, which was developed in the last few decades and has led to a radically new global view of the universe. Students and other interested readers will find here a non-technical but conceptually rigorous account of modern cosmological ideas - describing what we know, and how we know it. One of the book's central themes is the scientific quest to find answers to the ultimate cosmic questions: Is the universe finite or infinite? Has it existed forever? If not, when and how did it come into being? Will it ever end? The book is based on the undergraduate course taught by Alex Vilenkin at Tufts University. It assumes no prior knowledge of physics or mathematics beyond elementary high school math. The necessary physics background is introduced as it is required. Each chapter includes a list of questions and exercises of varying degree of difficulty.
Why do modern-day sluggers like Aaron Judge prefer maple bats over the traditional ash bats swung by Ted Williams and others? Why did the surge of broken bats in the early 21st century create a crisis for Major League Baseball and what steps were taken to address the issue? Are different woods being considered by players and manufacturers? Do insects, disease and climate change pose a problem long-term? These and other questions are answered in this exhaustive examination of the history and future of wooden bats, written for both lifelong baseball fans and curious newcomers.
