Free Download Hydraulic Machines and Energy by Giorgio Cornetti
English | EPUB (True) | 2024 | 418 Pages | ISBN : 3030916006 | 155.9 MB
This first volume of the textbook Hydraulic and Thermal Machines introduces readers to all necessary fundamentals to understand and operate hydraulic and thermal machines. No prior knowledge in machinery is required. With an uncomplicated yet rigorous approach, it gradually guides bachelor students, with no prior knowledge in machines, from basic concepts such as dimensions and SI base and derived units, to more complex, mathematical and mechanical fundamentals of hydraulic machines, energy conversion processes, fluids, including real ones, as well as hydrostatics and hydrodynamics. In turn, the book gets into the basic structure and operating modes of pumps and turbines, ending up with the study of fluid dynamic transmission in hydraulic machines. Numerous examples are analyzed in detail, for a comprehensive understanding and effective learning, which will prepare readers to the second volume of this set.

Free Download Optimization of SQL Queries for Parallel Machines By Waqar Hasan (eds.)
1996 | 140 Pages | ISBN: 3540620656 | PDF | 2 MB
Parallel execution of SQL queries against large databases offers a solution to the problem of reducing query response. This book addresses the related optimization problem: Given an SQL query, find the plan that delivers the result in minimal time. The author presents and analyzes new theoretical findings and efficient algorithms pertaining to parallel operation at a practical level of granularity relevant to database system operations. The optimization results balance the advantages and costs of parallel execution of SQL queries. The techniques presented are applicable to modern system configurations, where computation is performed on pipelining-capable workstations operating in parallel, and can be used to construct SQL compilers able to exploit parallel machines effectively.

Free Download Virtual Machines By Iain D. Craig MA, PhD, MBCS, CITP (auth.)
2006 | 269 Pages | ISBN: 1852339691 | PDF | 27 MB
Virtual Machines offers a unique insight into the building of virtual machines for sequential, object-oriented and parallel languages, and uses comparisons of different VMs to provide actual, practical examples on how to build VMs.State transitions are used as a formal technique for the specification of virtual machines throughout and – in addition – transitions and state transitions relating to the general operation are included for specification of the virtual machine for the event-based system. Two virtual machines are defined using a simple sequential language, which is then generalised to include object and parallelism. Other themes explored include the implementation of VMs and proposals for future work. Appendices contain high-level specifications of two compilers: one for the simple language that serves as the basic example throughout the book, the other for the event-based language specified in Chapter 6.This book is an essential reference tool for academic and industrial researchers as well as postgraduates in this area.
