This book extensively covers boundary integral equation (BIE) formulations and the boundary element method. Boundary integral equations are used to tackle linear, wave propagation, infinite domain, mobile boundaries, and unknown boundaries problems. Applications include the design of cars and spacecraft, concert hall acoustics, and the electromagnetism of submarines. The book's first section introduces BIE formulations for potential and elasticity problems, following the modern regularization approach. A description of BIE formulations for wave and elastodynamics problems is presented. Finally, recent research related to variational integral formulations, use of geometrical symmetry, shape sensitivity, and fracture mechanics is summarized.
This reference has alphabetically arranged descriptions of nearly every command in the newly released AutoCAD 2000, including toolbar and command line launch options and important command dialog boxes, with detailed descriptions of the various options available to the user. For advanced users who want to customize the software, there is information on system variables used for scripts, macros, and AutoLISP. An introduction includes a step-by-step guide to the Startup Wizard and setting up a new file, as well as a complete listing of all the new commands and a list of commands, new and old, broken out by function.
Recent developments in sensor and processor sophistication have created a need for effective estimation and control algorithms for hybrid, nonlinear systems. This book presents a family of algorithms that can be used in estimating or controlling a variety of nonlinear plants. Several applications are studied, including tracking a maneuvering aircraft, automatic target recognition, and decoding wireless communications signals. The authors set out the necessary theoretical background and then develop a practical, finite-dimensional approximation to an optimal estimator. They illustrate theoretical results by simulation of control and estimation in real-world hybrid systems, drawn from a variety of engineering fields.
This text was written to provide information on what lubricant products are available, what factors matter most in a lubricant, and which lubricants are most effective for specific applications. The full scope of industrial lubricants is addressed, including general purpose oils, hydraulic fluids, food-grade and environmentally friendly lubricants, synthetic lubricants, greases, pastes, waxes, and tribo-systems. Detailed coverage is provided on lubrication strategies for electric motor bearings, gear lubrication, compressors and gas engines, and steam and gas turbines. Other topics include proper lubricant handling and storage, as well as effective industrial plant oil analysis practices.
This book strives to demystify Six Sigma methods for today's users and offers guidance on how to choose and use Six Sigma tools effectively to become more competitive, reduce defect levels, and improve cycle times. It also consolidates the traditional Six Sigma process measurements and improvement tools with many other useful methodologies. The Six Sigma implementation road map that the book describes integrates basic methods, such as FMEA, QFD, process flowcharting, and continuous improvement tools (e.g., Pareto chart and cause-and-effect diagram) with a full range of powerful statistical techniques and concepts
This volume seeks to present a rational and unified treatment of coupled processes, with emphasis on the coupling and feedbacks present where solid deformation, fluid flow, and solute transport combine, and on the representation of heterogeneous media through multiporosity approaches. Analytical and numerical solutions are presented for subsurface systems subjected to varying mechanical, thermal, and chemical disturbances. Topics covered include theoretical bases and connections between deformation, flow, and transport in the subsurface; coupled and uncoupled processes and their respective restraints and significance; the effects of heterogeneities; and popular and special analytical and numerical methods in related fields.
Cellular solids include engineering honeycombs and foams (including those made from polymers, metals, ceramics, and composites) as well as natural materials, such as wood, cork, and cancellous bone. This text summarizes the current understanding of the structure and mechanical behavior of cellular materials, and the ways in which they can be exploited in engineering design. The new edition includes new work on the processing of metallic and ceramic foams and on the mechanical, electrical, and acoustic properties of cellular solids. Data for commercially available foams are presented on material property charts. Two new case studies demonstrate how the charts are used for selection of foams in engineering design.
The authors consider various methods of experimental study of thermal and caloric properties of pure substances and binary mixtures in wide ranges of variation of independent variables, including the near-critical region. The text includes experiment results said to be the principal information source for the great majority of properties of the most common substances and materials. Included is a brief survey of equipment designed in various laboratories in the former Soviet Union, describing the main units of the equipment, their characteristics, and the experimental procedures.
The National Academy of Engineering's Fifth Annual Symposium on Frontiers of Engineering was held in Irvine, Calif., in October 1999. The papers collected in this volume are extended summaries of the speakers' remarks. "Drowning in Data," a section on information technology, includes papers on magnetic data storage, large multiprocessor servers, and network survivability. The bioengineering and chemical engineering section includes articles on colloidal-scale engineering and the design of biomimetic polymeric materials. The energy and environment section discusses deregulation in the electric power industry, nuclear energy, and renewable energy technologies, and a section on optics deals with vertical-cavity, surface-emitting lasers and optical applications of MEMS.
