Understand and utilize the latest developments in Weibull inferential methods While the Weibull distribution is widely used in science and engineering, most engineers do not have the necessary statistical training to implement the methodology effectively. "Using the Weibull Distribution: Reliability, Modeling, " "and Inference "fills a gap in the current literature on the topic, introducing a self-contained presentation of the probabilistic basis for the methodology while providing powerful techniques for extracting information from data. The author explains the use of the Weibull distribution and its statistical and probabilistic basis, providing a wealth of material that is not available in the current literature. The book begins by outlining the fundamental probability and statistical concepts that serve as a foundation for subsequent topics of coverage, including: - Optimum burn-in, age and block replacement, warranties and renewal theory - Exact inference in Weibull regression - Goodness of fit testing and distinguishing the Weibull from the lognormal - Inference for the Three Parameter Weibull Throughout the book, a wealth of real-world examples showcases the discussed topics and each chapter concludes with a set of exercises, allowing readers to test their understanding of the presented material. In addition, a related website features the author's own software for implementing the discussed analyses along with a set of modules written in Mathcad(R), and additional graphical interface software for performing simulations. With its numerous hands-on examples, exercises, and software applications, "Using the Weibull Distribution "is an excellent book for courses on quality control and reliability" "engineering at the upper-undergraduate and graduate levels. The book also serves as a" "valuable reference for engineers, scientists, and business analysts who gather and interpret" "data that follows the Weibull distribution

Structures that are essential for economy and security such as energy production, transportation and supply, water supply, buildings, are susceptible to failure, because of defects already present in the material, or created at fabrication, or appearing during service. Methods of assesment of the nocivity of these defects are needed, to predict the remaining service life and the eventual emergency of stopping service and repairing, if possible. To reach this objectives, this book presents the last methods derived from the classical linear, non-linear fracture mechanics concepts, including fatigue and notch fracture mechanics. Several examples of structures rehabilitations and repairing are given. This book gathers the presentation made during the Advanced Research Workshop held in Portoroz (Slovenia) in October 2008, under the auspices of NATO Science for Peace and Security Programme. It is edited by Professor Guy Pluvinage from the University Paul Verlaine - Metz (France) and Professor Aleksandar Sedmak from the University of Belgrade, Faculty of Mechanical Engineering. Both have a long and rich experience in analysis of theoretical and practical cases in safety and reliability of structures. Other contributors are all known as experts in the areas of fatigue, facture and reliability of structures.

The book is an excellent guide for Marine Engineers, especially those who have just about started with a career out at sea. Lost in the confines of a never-seen-before engine room, this book brings a deep insight into the actual functioning and the ropes of maintaining machinery on a sea going vessel. Most books are written with the purpose of succeeding at the examinations for certification. This book discusses performance criteria of equipment in detail, maintenance based on those criteria with over 170 sketches, drawings and images, and troubleshooting to resolve problems faced on those rust buckets. The book emphasizes training to be a great manager, staying one step ahead of peers (and may be half a step ahead of superiors). Like they say - who needs mathematics to trace a choked filter, huh? A fun book and yet an eye-opener for those still to find their sea legs.

Powerful and elegantly simple.
The field of "On-Line Fault Detection and Supervision in the Chemical Process Industries" is relatively young. Major activity in this area has taken place only in the last fifteen years. The goals of the first workshop in Delaware were to discuss various methodologies necessary for solving industrial problems in fault diagnosis/supervision and to encourage interactions between academia and industry. This workshop also focused on development and evaluation of methodologies for on-line fault detection and supervision in the chemical process industries. It addressed theory, application, validation, performance and evaluation of methodologies such as parameter estimation, observers, parity equations, signal analysis methods, classification, rule-based systems with probabilistic approaches, fuzzy logic and neural networks. There are several trends that make the topic of this workshop especially relevant in today's world. The first is the tremendous advances made in automation and information technology that can potentially bring in an ever-increasing amount of information on to computer screens in the operating room of a plant. Avoiding problems of information overload and converting plant data to "on-line useful knowledge" is a key challenge. In some respects, one can draw parallels here to biological evolution where, over billions of years, human beings have evolved "mental models" to interpret the huge amount of information received through their senses. In the absence of the time advantage that evolution has had, we have to rely on methodologies such as those presented in this workshop to provide assistance to operators and engineers in interpreting plant information. A second trend that makes this field relevant in today's world is the increasing emphasis on environment and safety. Community activism and accidents such as those in Bhopal, India have caused media spotlights to be turned on the smallest of toxic releases or loss of life due to chemical accidents. The negative publicity generated by such events as well as the need to maintain the image of an environmentally conscious company make industry more sensitive to the issues of early detection of faults. The third trend that makes this field very relevant is that of
the globalization of the world economy. Increasing globalization of
the chemical process industry puts pressure on economic
competitiveness and higher productivity. This implies reduced
down-time due to faults, quick and flexible response of production
to supply and demand changes, increasing reliance on automation and
reduced personnel.
It is increasingly accepted that future dependable, real-time
digital computer control systems will have distributed
architectures. Advantages of distributed computer control systems
include the possibility of composing large systems out of
pre-tested components with minimal integration effort, their
well-defined fault containment properties and their capacity to
make effective use of mass-produced silicon chips. The IFAC Workshop series on Distributed Computer Control Systems
(DCCS) focuses on design requirements and fundamental principles
encountered in such systems and highlights and traces the growth of
key concepts at their various stages of development. Theoretical
and application-oriented viewpoints receive equal emphasis. These
Workshops also provide an excellent forum for the exchange of
information on recent technological advances and practices in the
distributed computer control field. The 1997 DCCS Workshop was notable for the attention given to
practical implementations of ideas that have been under discussion
for decades and maintained the high technical standard set by
previous Workshops in the series - the policy of concentrating on a
specific topic, inviting a number of key authors and of accepting
only a limited number of papers paid dividends.
This volume contains the proceedings of the IFAC Workshop on "Singular Solutions and Perturbations in Control Systems "(SSPCS-97) held at Pereslavl-Zalessky, Russia on 7-11 July 1997. The Workshop was sponsored by IFAC and organized jointly by the Russian National Committee of Automatic Control, the Program Systems Institute and the Institute for Information Transmission Problems at the Russian Academy of Sciences, and the University of Pereslavl. The objective of this workshop was to provide an international forum for the discussion of recent developments and advances in the fields of singular control problems, impulsive control, singular perturbations technique in control systems, computational problems and others. The Workshop was devoted both to theoretical and applicative aspects of the so-called "nonclassical" problems in the area of control theory, such as problems with singular perturbations, impulse and generalized controls. These problems arise in various areas of applications, including mechanics, information processing, medicine and economy. At the same time they stimulate the development of new mathematical tools in the classical theory of control and differential equations. All papers included in this volume are given in the form presented by the authors.
Control often follows predictions: predictive control has been highly successful in producing robust and practical solutions in many real-life, real-time applications. Adaptive prediction covers a variety of ways of adding 'intelligence' to predictive control techniques. Many different groups, with widely varying disciplinary backgrounds and approaches, are tackling the same problem from different angles; these groups are sometimes unaware of alternative approaches from other disciplines. This book attempts to give a unified and comprehensive coverage of the principles and methods that these groups have developed. It avoids basing its descriptions on very complex mathematical formulations but still gives a rigorous exposure to the subject, and illustrates the theory with many practical examples. It is chiefly aimed at students, researchers and practitioners, but will also be accessible to the non-specialist.
The term ""Taguchi methods"" was coined in the United States. It pertains to the evaluation and improvement of the robustness of products - or what may also be termed ""quality engineering"". The purpose of this book is to explain these terms and it is aimed at managers, technology developers and engineers of manufacturing enterprises. The book contains a general discussion about the productivity of manufacturing enterprises, which is equivalent to cost reduction and quality improvement at the following five manufacturing stages - technology development, product planning, product design, design of the production process and management of the production process.
Load-Oriented Manufacturing Control is unique as it gives comprehensive and self-contained principles for the implementation of an appropriate production control technique of general applicability. It is based on the "funnel model," a new approach to scheduling and scheduling control which has an extensive monitoring and diagnosis system. Its most important system components include throughput diagrams, load-oriented order release, schedule-oriented capacity planning and control. The "funnel model" is getting increasing implementation in manufacturing companies. It is available in numerous variants and is especially significant for the job-shop and series production. Load-Oriented Manufacturing Control provides a large number of practical examples and is therefore relatively easy to understand. It offers direct implementation of this new important technique in manufacturing scheduling and control.

Innerstadtische Schienenverkehrssysteme stossen bei steigender Verkehrsnachfrage zunehmend an ihre Grenzen. Die Sicherheit und die Leistungsfahigkeit dieser Verkehrssysteme werden wesentlich durch die eingesetzte Leit- und Sicherungstechnik bestimmt. Eine Ausweitung des Verkehrsangebots erfordert leistungsfahige signaltechnische Systeme, die als Communications-Based Train Control (CBTC) bezeichnet werden. Lars Schnieder stellt in diesem essential die Systemumgebung dar, in die sich die CBTC-Systeme in Nahverkehrsunternehmen integrieren. Daruber hinaus leitet er her, welchen Beitrag die einzelnen Sicherungsfunktionen von CBTC-Loesungen zur Gefahrdungsbeherrschung leisten. Auf dieser Grundlage zeigt der Autor, wie mit zunehmender Automatisierung sukzessive ein hoeherer Funktionsumfang von technischen Systemen ubernommen wird. Zum Abschluss diskutiert er an CBTC-Systeme gestellte nicht-funktionale Anforderungen wie Sicherheit, Verfugbarkeit, Leistungsfahigkeit und Wirtschaftlichkeit. Der Autor: Dr.-Ing. Lars Schnieder verantwortet in einer Software-Entwicklungsfirma das Geschaftsfeld Sicherheitsbegutachtung. Er ist international als anerkannter Sachverstandiger fur Zugsicherungsanlagen tatig.
Il presente testo si propone di far acquisire al lettore le conoscenze delle metodologie e teorie di base per effettuare analisi di sicurezza e valutazione del rischio in diversi ambienti aeronautici, in un quadro di Safety Management System. Vengono dapprima analizzati e descritti in dettaglio i metodi per effettuare studi prospettici di sicurezza di tipo probabilistico e per analisi quantitativa dei rischi associati a diversi pericoli nelle operazioni di volo, nella gestione delle operazioni di terra e nei processi manutentivi. Sono quindi presentate le metodologie formali per studi retrospettivi delle occorrenze ed incidenti, orientate alla ricerca delle cause ed alla definizione di raccomandazioni di sicurezza. Tutte le teorie sono inquadrate in un approccio sistemico, che prevede la valutazione integrata qualitativa e quantitativa dei rischi derivanti dai guasti meccanici e da fattori umani. Una serie di esempi semplici vengono associati alle diverse teorie e metodi presentati nel testo. Infine, per dimostrare praticamente come tali metodi si integrano in una valutazione globale del rischio, vengono discussi in dettaglio due esempi specifici di analisi prospettica del rischio associato ad un'operazione di volo e di studio retrospettivo di incidente, con relativa classificazione delle cause. |
