Computer Control and Human Error presents accounts of various incidents at computer-controlled plants. These incidents include equipment and software faults; treating the computer as a "black box"; misjudging the way operators respond to the computer; errors in the data entry; failure to inform operators of changes in data or programs; and unauthorized interference with peripheral equipment. The discussion then turns to the use of hazard and operability studies (Hazops) to prevent or reduce errors in computer-controlled plants. The book describes the conventional Hazop as used in the process industry and an overview of the different Chazop frameworks/guidelines suggested by engineers and researchers. It then presents new Chazop methodology which is based on incident analysis. The final chapter presents reasons for failures in computerized systems, each of which is illustrated with an example. Most of the examples did not cause an actual safety problem, simply because they occurred within systems that are not safety-related. Some of these examples appear in the literature; others are from personal experience or from private communications.
Over the past sixty years, the spectacular growth of the technologies associated with the computer is visible for all to see and experience. Yet, the science underpinning this technology is less visible and little understood outside the professional computer science community. As a scientific discipline, computer science stands alongside the likes of molecular biology and cognitive science as one of the most significant new sciences of the post Second World War era.
This celebrated primer presents an introduction to all of the key ingredients in understanding computerized adaptive testing technology, test development, statistics, and mental test theory. Based on years of research, this accessible book educates the novice and serves as a compendium of state-of-the-art information for professionals interested in computerized testing in the areas of education, psychology, and other related social sciences. A hypothetical test taken as a prelude to employment is used as a common example throughout to highlight this book's most important features and problems.
This is an anonymously written work that despite its age continues to be widely read today
Introduction to Computer Science Using Python: A Computational Problem-Solving Focus,recommended by Guido van Rossum, the creator of Python (?This is not your average Python book?I think this book is a great text for anyone teaching CS1?). With a focus on computational problem solving from Chapter 1, this text provides numerous hands-on exercises and examples, each chapter ending with a significant-size program demonstrating the step-by-step process of program development, testing, and debugging. A final chapter includes the history of computing, starting with Charles Babbage, containing over 65 historical images. An end-of-book Python 3 Programmers? Reference is also included for quick lookup of Python details. Extensive instructor materials are provided for those adopting for classroom use, including an instructors? manual, over 1,000 well-developed slides covering all fundamental topics of each chapter, source code, and test bank.Â
