This book addresses several issues related to the metrological characterization of high-performance pulsed power converters. Initially, a background and state-of-the-art on measurement systems for high-performance power converter are presented. In industrial applications of power converters metrology, specifications are often given in terms of worst-case uncertainty (WCU). Therefore, an analytical model for predicting the WCU of a measurement system is discussed and detailed for instruments affected by Gaussian noise. The authors discuss the study and design of a reference acquisition system for characterizing high-power pulses as well as the design of an on-line acquisition system for controlling the power converter. The book continues with numerical results obtained in simulation for the three main topics, which demonstrate the effectiveness of the proposals. Finally, the experimental results of a case study, carried out in the framework of the Compact Linear Collider (CLIC) at CERN, are reported. To meet CLIC requirements the two systems were designed to be ultra-low noise and are demonstrated to be repeatable in the order of few tens of parts per million (ppm).

In this book, advanced methods and techniques of monitoring, fault diagnostics, and predictive maintenance for cryogenics are illustrated. In Part I on Background, mainstreams in the related research are reviewed. In Part II of Methods, for monitoring helium distribution and consumption in cryogenic systems for particle accelerators, a virtual flowmeter is presented. Then, for fault diagnostics, two methods, for fault detection on a compressor, and for distributed diagnostics based on a micro-genetic algorithm, are described. Finally, for predictive maintenance, a metaheuristic optimization scheduling algorithm is illustrated. In Part III of Application examples, several practical case studies are described for highlighting the application of the previous methods to cryogenics of particle accelerators at CERN.

Lectures of a Course held at the Joint Research Centre, Ispra, Italy, November 11-18, 1981

This now famous anthology brings together various aspects of oversampling methods and compares and evaluates design approaches. It describes the theoretical analysis of converter performances, the actual design of converters and their simulation, circuit implementations, and applications.

Primarily intended for the undergraduate students of electronics and communication engineering, computer science and engineering, and information technology, this book skilfully integrates both the hardware and software aspects of the 8086 microprocessor. It offers the students an up-to-date account of the state-of-the-art microprocessors and therefore can be regarded as an incomparable source of information on recently developed microprocessor chips. The book covers the advanced microprocessor architecture of the Intel microprocessor family, from 8086 to Pentium 4. The text is organized in four parts. Part I (Chapters 1-7) includes a detailed description of the architecture, organization, instruction set, and assembler directives of microprocessor 8086. Part II (Chapters 8-11) discusses the math coprocessor, multiprocessing and multiprogramming, the different types of data transfer schemes, and memory concepts. Part III (Chapters 12-15) covers programmable interfacing chips with the help of extensive interfacing examples. Part IV (Chapters 16-18) deals with advanced processors--from 80186 to Pentium 4. This well-organized and student-friendly text should prone to be an invaluable asset to the students as well as the practising engineers. KEY FEATURES: Gives elaborate programming examples to develop the analytical ability of students. Provides solved examples covering different types of typical interfacing problems to develop the practical skills of students. Furnishes chapter-end exercises to reinforce the understanding of the subject.
