The author offers practical coverage of vibration stresses and stress-induced displacements, isolation of sensitive components, and evaluation of elastic instability, fatigue and fracture as potential failure modes that arise in mechanical designs and aerospace. The approach taken is particularly useful in the early design stage - the physical problem is defined via known parameters, and a methodology is given for determining the unknown quantities and relating them to specified limiting values and failure modes to obtain an acceptable design. Many of the calculations can be performed on a PC or programmable calculator.

PRACTICAL ENGINEERING STATISTICS
This lucidly written book offers engineers and advanced students all the essential statistical methods and techniques used in day-to-day engineering work. Without unnecessary digressions into formal proofs or derivations, Practical Engineering Statistics shows how to select the appropriate statistical method for a specific task and then how to apply it correctly and confidently. Clear explanations supported by real-world examples lead the reader step-by-step through each procedure. Topics covered include product design and development; estimations of the mean value and variability of measured data; comparison of processes or products; the relationships between variables; and more.
With its emphasis on practical use and its full range of engineering applications, Practical Engineering Statistics serves as an indispensable, time-saving reference for all engineers working in design, reliability, assurance, scheduling, and manufacturing.
PRACTICAL ENGINEERING STATISTICS
While engineers are frequently involved in projects that require the application of statistical methods to analysis, prediction, and planning, their background in statistics is often insufficient to the task. In many cases the engineer has had little training in statistics beyond the concepts of the mean, the standard deviation, the median, and the quartile. Even those who have had one or more courses in statistics will, at times, encounter problems which are beyond their capacity to solve or understand.
Practical Engineering Statistics is designed to give engineers the knowledge to select the statistical approach that is most appropriate to the problem at hand and the skills to confidently apply this approach to specific cases. It provides the engineer with the statistical tools needed to perform the job effectively, whether it is pro-duct design and development, estimation of the mean value and variability of measured data, comparison of processes or products, or the relationship between variables.
Its authors bring two different areas of expertise to this unique book: statistics and engineering physics. In Practical Engineering Statistics their collaboration has produced a book that clearly leads engineers step-by-step through each procedure, without time-consuming and unnecessary discussions of proofs and derivations. Statistical procedures are discussed and explained in detail and demonstrated through real-world sample problems, with correct answers always provided. Readers learn how to determine which data represent true observations and which, through human error or flawed data, are false observations.
Complex problems are presented with computer printouts of the database, intermediate steps, and results. Numerous illustrations and tables of all commonly used distributions enhance the usefulness of this invaluable book.
Virtually all engineers and advanced students, especially those in mechanical, civil, electrical, aerospace, and chemical engineering, Practical Engineering Statistics is an indispensable reference that will give them the tools to do the statistical part of their work quickly and accurately.

Plum and Posner's Diagnosis and Treatment of Stupor and Coma, 5th edition, is a major update of the classic work on diagnosing the cause of coma, with the addition of completely new sections on treatment of comatose patients, by Dr. Jan Claassen, the Director of the Neuro-ICU at Columbia New York Presbyterian Hospital. The first chapter of the book provides an up-to-date review on the brain mechanisms that maintain a conscious state in humans, and how lesions that damage these mechanisms cause loss of consciousness or coma. The second chapter reviews the neurological examination of the comatose patient, which provides the basis for determining whether the patient is suffering from a structural brain injury causing the coma, or from a metabolic disorder of consciousness. The third and fourth chapters review the pathophysiology of structural lesions causing coma, and the specific disease states that result in coma. Chapter five is a comprehensive treatment of the many causes of metabolic coma. Chapter 6 review psychiatric causes of unresponsiveness and how to identify and treat them. Chapters 7 and 8 review the overall emergency treatment of comatose patients, followed by the treatment of specific causes of coma. Chapter 9 examines the long term outcomes of coma, including the minimally conscious state and the persistent vegetative state, and how they can be distinguished, and their implications for eventual useful recovery. Chapter 10 reviews the topic of brain death and the standards for examination of a patient that are required to make the determination of brain death. The final chapter 11 is by J.J. Fins, a medical ethicist who was invited by the other authors to write an essay on the ethics of diagnosis and treatment of patients who, by definition, have no way to approve of or communicate about their wishes. While providing detailed background for neurological and neurosurgical specialists, the practical nature of the material in this book has found its greatest use among Internists, Emergency Medicine, and Intensive Care specialists, who deal with comatose patients frequently, but who may not have had extensive neurological training.
