Book excerpt: THE HALT PERSPECTIVE 2 This volume printed with wherever possible color images and photographs celebrates the commitment taken by retired USAF Colonel Charles Irwin Halt, now in his 80th year - often in the face of adversity and media ignorance - to create awareness of the existence of a phenomenon that continues to haunt the skies of the world, on what is now the 40th Anniversary of the UFO incident that took place in Rendlesham Forest, Suffolk, England at the end of December 1980. Colonel Charles Irwin Halt will comment on many inexplicable UFO sightings brought to his attention by John Hanson, during 25 years of research from the mid to late 20th Century, both in the US and UK. He agrees that the events which took place in Rendlesham Forest, Suffolk, just outside the American Air Base - nowover 40 years ago - which have excited the imagination of the public, should not be judged in its singularity. Surely common sense dictates that any judgement as to what happened in December 1980 cannot be reached without taking into consideration the enormous number of sightings of UFO activity, including many which took place in the East Anglia region. Never mind elsewhere! These include important interviews with pilots and senior RAF officers. Followed by respects paid to the work and life of the late Washington-based UFO researcher, Richard 'Dick' 'H' Hall who was a friend of Colonel Halt. Our journey begins... "It is simply that, in the long run, the sheer weight of observational evidence finally broke down the barriers of disbelief."(Source: 'Other Worlds Than Ours' C. Maxwell Cade)

Download or read book Three Views of Logic written by Donald W. Loveland and published by Princeton University Press. This book was released on 2014-01-26 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first interdisciplinary textbook to introduce students to three critical areas in applied logic Demonstrating the different roles that logic plays in the disciplines of computer science, mathematics, and philosophy, this concise undergraduate textbook covers select topics from three different areas of logic: proof theory, computability theory, and nonclassical logic. The book balances accessibility, breadth, and rigor, and is designed so that its materials will fit into a single semester. Its distinctive presentation of traditional logic material will enhance readers' capabilities and mathematical maturity. The proof theory portion presents classical propositional logic and first-order logic using a computer-oriented (resolution) formal system. Linear resolution and its connection to the programming language Prolog are also treated. The computability component offers a machine model and mathematical model for computation, proves the equivalence of the two approaches, and includes famous decision problems unsolvable by an algorithm. The section on nonclassical logic discusses the shortcomings of classical logic in its treatment of implication and an alternate approach that improves upon it: Anderson and Belnap's relevance logic. Applications are included in each section. The material on a four-valued semantics for relevance logic is presented in textbook form for the first time. Aimed at upper-level undergraduates of moderate analytical background, Three Views of Logic will be useful in a variety of classroom settings. Gives an exceptionally broad view of logic Treats traditional logic in a modern format Presents relevance logic with applications Provides an ideal text for a variety of one-semester upper-level undergraduate courses
Download or read book Next Generation HALT and HASS written by Kirk A. Gray and published by John Wiley & Sons. This book was released on 2016-03-11 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Next Generation HALT and HASS presents a major paradigm shift from reliability prediction-based methods to discovery of electronic systems reliability risks. This is achieved by integrating highly accelerated life test (HALT) and highly accelerated stress screen (HASS) into a physics-of-failure-based robust product and process development methodology. The new methodologies challenge misleading and sometimes costly mis-application of probabilistic failure prediction methods (FPM) and provide a new deterministic map for reliability development. The authors clearly explain the new approach with a logical progression of problem statement and solutions. The book helps engineers employ HALT and HASS by illustrating why the misleading assumptions used for FPM are invalid. Next, the application of HALT and HASS empirical discovery methods to quickly find unreliable elements in electronics systems gives readers practical insight to the techniques. The physics of HALT and HASS methodologies are highlighted, illustrating how they uncover and isolate software failures due to hardware-software interactions in digital systems. The use of empirical operational stress limits for the development of future tools and reliability discriminators is described. Key features: * Provides a clear basis for moving from statistical reliability prediction models to practical methods of insuring and improving reliability. * Challenges existing failure prediction methodologies by highlighting their limitations using real field data. * Explains a practical approach to why and how HALT and HASS are applied to electronics and electromechanical systems. * Presents opportunities to develop reliability test discriminators for prognostics using empirical stress limits. * Guides engineers and managers on the benefits of the deterministic and more efficient methods of HALT and HASS. * Integrates the empirical limit discovery methods of HALT and HASS into a physics of failure based robust product and process development process.
Download or read book Perspectives in Computation written by Robert Geroch and published by University of Chicago Press. This book was released on 2009-09-15 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computation is the process of applying a procedure or algorithm to the solution of a mathematical problem. Mathematicians and physicists have been occupied for many decades pondering which problems can be solved by which procedures, and, for those that can be solved, how this can most efficiently be done. In recent years, quantum mechanics has augmented our understanding of the process of computation and of its limitations. Perspectives in Computation covers three broad topics: the computation process and its limitations, the search for computational efficiency, and the role of quantum mechanics in computation. The emphasis is theoretical; Robert Geroch asks what can be done, and what, in principle, are the limitations on what can be done? Geroch guides readers through these topics by combining general discussions of broader issues with precise mathematical formulations—as well as through examples of how computation works. Requiring little technical knowledge of mathematics or physics, Perspectives in Computation will serve both advanced undergraduates and graduate students in mathematics and physics, as well as other scientists working in adjacent fields.

Download or read book Algorithms for Random Generation and Counting A Markov Chain Approach written by A. Sinclair and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is a slightly revised version of my PhD thesis [86], com pleted in the Department of Computer Science at the University of Edin burgh in June 1988, with an additional chapter summarising more recent developments. Some of the material has appeared in the form of papers [50,88]. The underlying theme of the monograph is the study of two classical problems: counting the elements of a finite set of combinatorial structures, and generating them uniformly at random. In their exact form, these prob lems appear to be intractable for many important structures, so interest has focused on finding efficient randomised algorithms that solve them ap proxim~ly, with a small probability of error. For most natural structures the two problems are intimately connected at this level of approximation, so it is natural to study them together. At the heart of the monograph is a single algorithmic paradigm: sim ulate a Markov chain whose states are combinatorial structures and which converges to a known probability distribution over them. This technique has applications not only in combinatorial counting and generation, but also in several other areas such as statistical physics and combinatorial optimi sation. The efficiency of the technique in any application depends crucially on the rate of convergence of the Markov chain.

Download or read book HALT HASS and HASA Explained written by Harry W. McLean and published by Quality Press. This book was released on 2008-12-12 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: This groundbreaking resource book is the place where readers will find all that is required to implement a successful accelerated reliability program. It has been prepared with both novices and experts in mind. It has been written so that either can find information that will aid them in their quest to produce high-reliability products without getting bogged down in equations. HALT, a process for the ruggedization of preproduction products, and HASS, the production screen for the products once they have been characterized in HALT, are the primary focal points in this book. For those wishing to delve into more advanced topics, three versions of a production audit, HASA, are also included. These may be of interest to the high-volume producer or to those who wish to audit their overall production processes rather than to screen all of the products. Author Harry McLean shares the knowledge he has acquired in helping employers and clients manufacture products which far exceeded stated reliability expectations as soon as they were released into production. Many who are using these techniques are included in the world’s top 50 electronic and electromechanical companies and have seen their market share climb from “the dust in the rear of the pack” to be the industry leader in a short time. Others have used HALT, HASS, and HASA techniques to increase warranty coverage for their products three times the industry norm and still reduce their overall warranty expense as well as to dramatically increase their market share. Others have used them to assist in the winning of the coveted Baldrige award.
