Powerline Ampacity System

www.ebooks.com/cj.asp?IID=264230&cjsku=264230...
Civilization's demands for electricity continue to grow, yet environmental, regulatory, and economic constraints often preclude the construction of new power plants and transmission lines. The challenge now faced by engineers, equipment manufacturers, and regulatory agencies is to find ways to maximize the capacity of existing power lines. Powerline Ampacity System is the first step in meeting that challenge. Along with developing a complete theory of transmission line ampacity, the author uses object-oriented modeling and expert rules to build a power line ampacity system. He describes new transmission line conductor technologies and power electronics FACTS devices that can take full advantage of a dynamic line rating system. He offers examples that clearly show the economic benefit of operating an interconnected transmission network that has a diverse mix of electricity generation sources. He also discusses - with examples - generator stability enhancement by dynamic line rating.

Embedded System Design

www.ebooks.com/cj.asp?IID=95831192&cjsku=95831192...
A unique feature of this textbook is to provide a comprehensive introduction to the fundamental knowledge in embedded systems, with applications in cyber-physical systems and the Internet of things. It starts with an introduction to the field and a survey of specification models and languages for embedded and cyber-physical systems. It provides a brief overview of hardware devices used for such systems and presents the essentials of system software for embedded systems, including real-time operating systems. The author also discusses evaluation and validation techniques for embedded systems and provides an overview of techniques for mapping applications to execution platforms, including multi-core platforms. Embedded systems have to operate under tight constraints and, hence, the book also contains a selected set of optimization techniques, including software optimization techniques. The book closes with a brief survey on testing. This third edition has been updated and revised to reflect new trends and technologies, such as the importance of cyber-physical systems and the Internet of things, the evolution of single-core processors to multi-core processors, and the increased importance of energy efficiency and thermal issues.

Computer System Organization

www.ebooks.com/cj.asp?IID=1876822&cjsku=1876822...
Computer System Organization: The B5700/B6700 Series focuses on the organization of the B5700/B6700 Series developed by Burroughs Corp. More specifically, it examines how computer systems can (or should) be organized to support, and hence make more efficient, the running of computer programs that evolve with characteristically similar information structures. Comprised of nine chapters, this book begins with a background on the development of the B5700/B6700 operating systems, paying particular attention to their hardware/software architecture. The discussion then turns to the block-structured processes involved in the B6700 job, which consists of a time-invariant algorithm and a time-varying data structure which is the record of execution of that algorithm. Subsequent chapters deal with the basic data structures for B6700 algorithms; task attributes and the creation and coordination of tasks; stack structure and stack ownership; and software interrupts. Storage control strategies as well as the pros and cons of B6700 are also considered, along with some hardware details of procedure entry and return and tasking. This monograph is intended for computer center directors, other computer professionals, and serious students in computer science who have an interest in the subject of computer organization.

System Performance Tuning

www.ebooks.com/cj.asp?IID=443176&cjsku=443176...
System Performance Tuning answers one of the most fundamental questions you can ask about your computer: How can I get it to do more work without buying more hardware? In the current economic downturn, performance tuning takes on a new importance. It allows system administrators to make the best use of existing systems and minimize the purchase of new equipment. Well-tuned systems save money and time that would otherwise be wasted dealing with slowdowns and errors. Performance tuning always involves compromises; unless system administrators know what the compromises are, they can't make intelligent decisions.Tuning is an essential skill for system administrators who face the problem of adapting the speed of a computer system to the speed requirements imposed by the real world. It requires a detailed understanding of the inner workings of the computer and its architecture. System Performance Tuning covers two distinct areas: performance tuning, or the art of increasing performance for a specific application, and capacity planning, or deciding what hardware best fulfills a given role. Underpinning both subjects is the science of computer architecture. This book focuses on the operating system, the underlying hardware, and their interactions. Topics covered include: Real and perceived performance problems, introducing capacity planning and performance monitoring (highlighting their strengths and weaknesses). An integrated description of all the major tools at a system administrator's disposal for tracking down system performance problems. Background on modern memory handling techniques, including the memory-caching filesystem implementations in Solaris and AIX. Updated sections on memory conservation and computing memory requirements. In depth discussion of disk interfaces, bandwidth capacity considerations, and RAID systems. Comprehensive discussion of NFS and greatly expanded discussion of networking. Workload management and code tuning. Special topics such as tuning Web servers for various types of content delivery and developments in cross-machine parallel computing For system administrators who want a hands-on introduction to system performance, this is the book to recommend.
