This book leads directly to the most modern numerical techniques for compressible fluid flow, with special consideration given to astrophysical applications. Emphasis is put on high-resolution shock-capturing finite-volume schemes based on Riemann solvers. The applications of such schemes, in particular the PPM method, are given and include large-scale simulations of supernova explosions by core collapse and thermonuclear burning and astrophysical jets. Parts two and three treat radiation hydrodynamics. The power of adaptive (moving) grids is demonstrated with a number of stellar-physical simulations showing very crispy shock-front structures.

These notes developed from a course on the numerical solution of conservation laws first taught at the University of Washington in the fall of 1988 and then at ETH during the following spring. The overall emphasis is on studying the mathematical tools that are essential in de veloping, analyzing, and successfully using numerical methods for nonlinear systems of conservation laws, particularly for problems involving shock waves. A reasonable un derstanding of the mathematical structure of these equations and their solutions is first required, and Part I of these notes deals with this theory. Part II deals more directly with numerical methods, again with the emphasis on general tools that are of broad use. I have stressed the underlying ideas used in various classes of methods rather than present ing the most sophisticated methods in great detail. My aim was to provide a sufficient background that students could then approach the current research literature with the necessary tools and understanding. Without the wonders of TeX and LaTeX, these notes would never have been put together. The professional-looking results perhaps obscure the fact that these are indeed lecture notes. Some sections have been reworked several times by now, but others are still preliminary. I can only hope that the errors are. not too blatant. Moreover, the breadth and depth of coverage was limited by the length of these courses, and some parts are rather sketchy.
Former Air Force Colonel Randall J. Larsen has dedicated his career to keeping America safe. The man who many consider to be one of the foremost experts on homeland security now believes that America's government and citizens often stand in the way of their own safety--by asking the wrong questions. With the specter of ever-growing, dangerous threats, OUR OWN WORST ENEMY is a crucial book for every family. In it, Larsen offers a meticulous examination of the key issues that contribute to national security, such as the economy, border protection and immigration, and national health care. He also identifies why the government is not prepared to help us in a time of crisis (e.g. Hurricane Katrina), and lays out how citizens, communities, and businesses can protect themselves, their families, and their assets. Larsen's strict assessment will have readers asking, 'Who should be in charge of logistics during a major disaster?' 'How do we prevent a terrorist organization from becoming a nuclear power?' and 'What can I do to prepare myself and my family?'
In Duty is Ours, Results are God's, Captain Randall J. Jansen tells of his tough and demanding yet adventurous and exciting nine years in the US Marine Corps. He discusses principles to follow and life lessons to be learned, along with interesting and sometimes funny stories.Jansen began as a private in boot camp and later earned his officer's commission and naval aviator wings through attending flight school at the Naval Air Station in Pensacola, Florida. Graduation was followed by his worldwide service as a helicopter pilot in the Caribbean Sea, the Mediterranean Sea, and Vietnam. Jansen was seriously wounded on his 248th combat flight mission during the Vietnam War, the resulting disability of which led to his mandatory retirement from the US Marine Corps.Following his career in the Marine Corps, Jansen transitioned back to civilian life and began an extended investigation into some critical and perplexing questions. Why would someone voluntarily serve or commit to duty which could result in serious injury or death? Is service worth it? Where do we get the concept of freedom, liberty, purpose, or self-sacrifice? Is there absolute truth or is everything relative? Is there a correct, reasonable, or logical worldview by which people should live? If there is, how does someone find it and then live it?

Will America find enough good teachers to staff its public schools? How can we ensure that all our children will be taught by skilled professionals? The policies that determine who teaches today are a confusing and often conflicting array that includes tougher licensing requirements, higher salaries, mandatory master's degrees, merit pay, and alternative routes to certification. Who Will Teach? examines these policies and separates those that work from those that backfire.The authors present an intriguing portrait of America's teachers and reveal who they are, who they have been, and who they will be. Using innovative statistical methods to track the professional lives of more than 50,000 college graduates, the book describes, in many cases for the first time, just how prospective, current, and former teachers respond to the incentives and disincentives they face. The authors, a group of noted educators, economists, and statisticians, find cause for serious concern. Few academically talented college graduates even try teaching, and many of those who do leave quickly, never to return. Current licensing requirements stifle innovation in training and dissuade many potentially talented teachers at the outset.But Who Will Teach? shows that we can reverse these trends if we get the incentives right. Although better salaries are essential, especially for new teachers, money is not enough. Potential teachers should be offered alternative paths into the classroom. School districts should improve their recruiting strategies. Licensing criteria should assess teaching skills, not just academic achievement and number of courses completed. The authors offer a promising strategy based on high standards and substantial rewards.

Bible passages are based upon the English Standard Version of the Bible.
While I was visiting Boston University during the 1996-97 academic year, I noticed a small book, written in German, on a shelf in Steve Homer's office. Curious, I borrowed it for my train ride home and began reading one of the chapters. I liked the style and format of the book so much that over the course of the next few months I frequently found myself reaching for it and working through one chapter or another. This was my introduction to Peden der Theoretischen Informatik. A few of my colleagues had also seen the book. They also found it inter esting, but most of them did not read German well enough to read more than small portions of it enjoyably. I hope that the English version will rectify this situation, and that many will enjoy (and learn from) the English version as much as I enjoyed the German version. The front matter of this book says that it has been "translated, revised, and expanded." I should perhaps say a few words about each of these tasks. In translating the book, Ihave tried as much as possible to retain the feel of the original, which is somewhat less formal and impersonal than a typical text book yet relatively concise. I certainly hope that the "pleasure of the pursuit of understanding" has not gotten lost in the translation.
This book is a revised and expanded edition of a successful graduate and reference text. The material in the book is designed for a standard graduate course on probability theory, including some important applications. This new edition contains a detailed treatment of the core area of probability, and both structural and limit results are presented in full detail. Compared to the first edition, the material and presentation are better highlighted with several (small and large) alterations made to each chapter. Key features of the book include: - Indicating the need for abstract theory even in applications and showing the inadequacy of existing results for certain apparently simple real-world problems - Attempting to deal with the existence problems for various classes of random families that figure in the main results of the subject - Providing a treatment of conditional expectations and of conditional probabilities that is more complete than in other existing textbooks Since this is a textbook, essentially all proofs are given in complete detail (even at the risk of repetition), and some key results are given multiple proofs when each argument has something to contribute.

This book addresses an important class of mathematical problems (the Riemann problem) for first-order hyperbolic partial differential equations (PDEs), which arise when modeling wave propagation in applications such as fluid dynamics, traffic flow, acoustics, and elasticity.It covers the fundamental ideas related to classical Riemann solutions, including their special structure and the types of waves that arise, as well as the ideas behind fast approximate solvers for the Riemann problem.The emphasis is on the general ideas, but each chapter delves into a particular application. The book is available in electronic form as a collection of Jupyter notebooks that contain executable computer code and interactive figures and animations.
