The emphasis of this textbook is on industrial applications of Statistical Measurement Theory. It deals with the principal issues of measurement theory, is concise and intelligibly written, and to a wide extent self-contained. Difficult theoretical issues are separated from the mainstream presentation. Each topic starts with an informal introduction followed by an example, the rigorous problem formulation, solution method, and a detailed numerical solution. Each chapter concludes with a set of exercises of increasing difficulty, mostly with solutions. The book is meant as a text for graduate students and a reference for researchers and industrial experts specializing in measurement and measurement data analysis for quality control, quality engineering and industrial process improvement using statistical methods. Knowledge of calculus and fundamental probability and statistics is required for the understanding of its contents.
Maintaining an optimal blend of theory and practice, this readily
accessible reference/text details the utility of system dynamics
for analysis and design of mechanical, electrical, fluid, thermal,
and "mixed" engineering systems-addressing topics from system
elements and simple first- and second-order systems to complex
lumped- and distributed-parameter models of practical machines and
processes. Emphasizing digital simulation and integrating
frequency-response methods throughout, System Dynamics furnishes
up-to-date and thorough discussions on relations between real
system components and ideal math models continuous-time dynamic
system simulation methods, such as MATLAB/SIMULINK analytical
techniques, such as classical D-operator and Laplace transform
methods for differential equation solutions and linearization
methods vibration, electromechanics, and mechatronics Fourier
spectrum treatment of periodic functions, and transients and much
more System Dynamics also contains a host of self-study and
pedagogical features that will make it a useful companion for years
to come, such as easy-to-understand simulation diagrams and results
applications to real-life systems--including actual industrial
hardware intentional use of nonlinearity to achieve optimal designs
numerous end-of-chapter problems and worked examples over 1425
graphs, equations, and drawings throughout the text the latest
references to key sources in the literature Serving as a foundation
for engineering experience, System Dynamics is a valuable reference
for mechanical, system, control/instrumentation, and
sensor/actuator engineers as well as an indispensable textbook for
undergraduate students taking courses such as Dynamic Systems in
departments of mechanical, aerospace, electrical, agricultural, and
industrial engineering and engineering physics.
Accurate Visual Metrology from Single and Multiple Uncalibrated
Images presents novel techniques for constructing three-dimensional
models from bi-dimensional images using virtual reality tools.
Antonio Criminisi develops the mathematical theory of computing
world measurements from single images, and builds up a hierarchy of
novel, flexible techniques to make measurements and reconstruct
three-dimensional scenes from uncalibrated images, paying
particular attention to the accuracy of the reconstruction.
This book includes examples of interesting viable applications (eg.
Forensic Science, History of Art, Virtual Reality, Architectural
and indoor measurements), presented in a simple way, accompanied by
pictures, diagrams and plenty of worked examples to help the reader
understand and implement the algorithms.
The objective of this book is to give well-grounded methods for
estimation of the uncertainly of measurement results. Starting from
the basics of metrology, the book studies this subject in detail,
from theoretical analysis all the way to concrete practical
recommendations in areas ranging from single measurements in
industry, trade, etc. to multiple measurements in experimental
sciences. The book derives these recommendations by systematic
development of the measurement accuracy theory. An important aspect
of this book is that it develops the theory from the strong
practical perspective, by giving priority to the physical essence
of the problems and paying special attention to properties of
measuring instruments and their influence on the uncertainty of
measurements. The book also presents basics on characterization,
standardization and calibration of measuring instruments as well as
methods for calculating limits of errors of measuring instruments.
All recommendations are illustrated by detailed examples from
measurements of both electrical and mechanical quantities.
There is an increasing demand for dynamic systems to become safer, more reliable and more economical in operation. This requirement extends beyond the normally accepted safety-critical systems e.g., nuclear reactors, aircraft and many chemical processes, to systems such as autonomous vehicles and some process control systems where the system availability is vital. The field of fault diagnosis for dynamic systems (including fault detection and isolation) has become an important topic of research. Many applications of qualitative and quantitative modelling, statistical processing and neural networks are now being planned and developed in complex engineering systems. Issues of Fault Diagnosis for Dynamic Systems has been prepared by experts in fault detection and isolation (FDI) and fault diagnosis with wide ranging experience.Subjects featured include: - Real plant application studies; - Non-linear observer methods; - Robust approaches to FDI; - The use of parity equations; - Statistical process monitoring; - Qualitative modelling for diagnosis; - Parameter estimation approaches to FDI; - Fault diagnosis for descriptor systems; - FDI in inertial navigation; - Stuctured approaches to FDI; - Change detection methods; - Bio-medical studies. Researchers and industrial experts will appreciate the combination of practical issues and mathematical theory with many examples. Control engineers will profit from the application studies.
This book contains a number of problems with signal detection theory. A generalized observation model for signal detection problems, is presented. The model includes several interesting and common special cases such as those describing additive noise, multiplicative noise, and signal-dependent noise. This model can also describe composite signals in addition to the usual known (deterministic) signals and random (stochastic) signals. Locally optimum (LO) and locally optimum rank (LOR) detectors for known and random signals in the model, are discussed, and original results are obtained. Other approaches to detection of signals also are discussed.
Branch-and-bound search has been known for a long time and has been
widely used in solving a variety of problems in computer-aided
design (CAD) and many important optimization problems. In many
applications, the classic branch-and-bound search methods perform
duplications of computations, or rely on the search decision trees
which keep track of the branch-and-bound search processes. In CAD
and many other technical fields, the computational cost of
constructing branch-and-bound search decision trees in solving
large scale problems is prohibitive and duplications of
computations are intolerable. Efficient branch-and-bound methods
are needed to deal with today's computational challenges. Efficient
branch-and-bound methods must not duplicate computations. Efficient
Branch and Bound Search with Application to Computer-Aided Design
describes an efficient branch-and-bound method for logic
justification, which is fundamental to automatic test pattern
generation (ATPG), redundancy identification, logic synthesis,
minimization, verification, and other problems in CAD. The method
is called justification equivalence, based on the observation that
justification processes may share identical subsequent search
decision sequences. With justification equivalence, duplication of
computations is avoided in the dynamic branch-and-bound search
process without using search decision trees. Efficient Branch and
Bound Search with Application to Computer-Aided Design consists of
two parts. The first part, containing the first three chapters,
provides the theoretical work. The second part deals with
applications, particularly ATPG for sequential circuits. This book
is particularly useful to readers who are interested in the design
and test of digital circuits.

The object of this book is to provide a comprehensive treatment of the principal issues in modern instrumentation, but without attempting an encyclopedic reference. It thus discusses the basic theory and physical principles underlying the operation of the various sensors as well as the practical aspects of their operation and their incorporation into larger systems. The intent is to cover the most important topics in electronics, sensors, measurements, and acquisition systems, always keeping in mind the needs of practicing scientists and engineers. The presentation focuses on systems controlled by desktop personal computers running a high-level program and operating through internal cards or an external bus connected to instruments, rather than the specialized microprocessors discussed in older texts. The book will thus be useful to students in a wide variety of experimental sciences and engineering disciplines, including physics, chemistry, mechanical, nuclear, and electrical engineering, experimental psychology, biology, and geophysics.
This book contains selected contributions from the 6th CIRP
International Seminar on Computer-Aided Tolerancing, which was held
on 22-24 March, 1999, at the University of Twente, Enschede, The
Netherlands. This volume presents the theory and application of
consistent tolerancing. Until recently CADCAM systems did not even
address the issue of tolerances and focused purely on nominal
geometry. Therefore, CAD data was only of limited use for the
downstream processes. The latest generation of CADCAM systems
incorporates functionality for tolerance specification. However,
the lack of consistency in existing tolerancing standards and
everyday tolerancing practice still lead to ill-defined products,
excessive manufacturing costs and unexpected failures. Research and
improvement of education in tolerancing are hot items today. Global
Consistency of Tolerances gives an excellent overview of the recent
developments in the field of Computer-Aided Tolerancing, including
such topics as tolerance specification; tolerance analysis;
tolerance synthesis; tolerance representation; geometric product
specification; functional product analysis; statistical
tolerancing; education of tolerancing; computational metrology;
tolerancing standards; and industrial applications and CAT systems.
This book is well suited to users of new generation CADCAM systems
who want to use the available tolerancing possibilities properly.
It can also be used as a starting point for research activities.
Throughout the 1980s and 1990s, the theory and practice of testing
electronic products has changed considerably. Quality and testing
have become inextricably linked and both are fundamental to the
generation of revenue to a company, helping the company to remain
profitable and therefore survive. Testing plays an important role
in assessing the quality of a product. The tester acts as a filter,
separating good products from bad. Unfortunately, the tester can
pass bad products and fail good products, and the generation of
high quality tests has become complex and time consuming. To
achieve significant reduction in time and cost of testing, the role
and responsibility of testing has to be considered across an entire
organization and product development process. Testability Concepts
for Digital ICs: The Macro Test Approach considers testability
aspects for digital ICs. The strategy taken is to integrate the
testability aspects into the design and manufacturing of ICs and,
for each IC design project, to give a precise definition of the
boundary conditions, responsibilities, interfaces and
communications between persons, and quality targets. Macro Test, a
design-for-Testability approach, provides a manageable test program
route. Using the Macro Test approach, one can explore alternative
solutions to satisfy pre-defined levels of performance (e.g. defect
detection, defect location, test application) within a pre-defined
cost budget and time scale. Testability Concepts for Digital ICs is
the first book to present a tried and proven method of using a
Macro approach to testing complex ICs and is of particular interest
to all test engineers, IC designers and managers concerned with
producing highquality ICs.
Computer Aided Tolerancing (CAT) is an important topic in any field
of design and production where parts move relative to one another
and/or are assembled together. Geometric variations from specified
dimensions and form always occur when parts are manufactured.
Improvements in production systems can cause the amounts of the
variations to become smaller, but their presence does not
disappear. To shorten the time from concept to market of a product,
it has been increasingly important to take clearances and the
tolerancing of manufacturing variations into consideration right
from the beginning, at the stage of design. Hence, geometric models
are defined that represent both the complete array of geometric
variations possible during manufacture and also the influence of
geometry on the function of individual parts and on assemblies of
them...
Metrology and Properties of Engineering Surfaces provides in a
single volume a comprehensive and authoritative treatment of the
crucial topics involved in the metrology and properties of
engineering surfaces. The subject matter is a central issue in
manufacturing technology, since the quality and reliability of
manufactured components depend greatly upon the selection and
qualities of the appropriate materials as ascertained through
measurement. The book can in broad terms be split into two parts;
the first deals with the metrology of engineering surfaces and
covers the important issues relating to the measurement and
characterization of surfaces in both two and three dimensions. This
covers topics such as filtering, power spectral densities,
autocorrelation functions and the use of Fractals in topography. A
significant proportion is dedicated to the calibration of scanning
probe microscopes using the latest techniques. The remainder of the
book deals with the properties of engineering surfaces and covers a
wide range of topics including hardness (measurement and
relevance), surface damage and the machining of brittle surfaces,
the characterization of automobile cylinder bores using different
techniques including artificial neural networks and the design and
use of polymer bearings in microelectromechanical devices. Edited
by three practitioners with a wide knowledge of the subject and the
community, Metrology and Properties of Engineering Surfaces brings
together leading academics and practitioners in a comprehensive and
insightful treatment of the subject. The book is an essential
reference work both for researchers working and teaching in the
technology and for industrial users who need to be aware of current
developments of the technology and new areas of application.
Theory and practice of tolerances are very important for designing
and manufacturing engineering artifacts on a rational basis.
Tolerance specifies a degree of "discrepancy" between an idealized
object and its physical realization. Such discrepancy inevitably
comes into our product realization processes because of practical
cost consideration or our inability to fully control manufacturing
processes. Major product and production characteristics which are
affected by tolerances are product quality and cost. For achieving
high precision machines tight tolerance specification is necessary,
but this will normally increase product cost. In order to optimally
compromise the conflicting requirements of quality and cost, it is
essential to take into account of the total product life cycle
throughout product planning, design, manufacturing, maintenance and
recycling. For example, in order to construct durable products
under severe working conditions, low sensitivity of product
functionality with respect to tolerances is required. In future,
re-use of components or parts will become important, and tolerance
synthesis with respect to this aspect will be an interesting future
research topics.
Tbis book is basicaUy concemed with approaches for improving safety
in man-made systems. We caU these approaches, coUectively, fault
monitoring, since they are concemed primarily with detecting faults
occurring in the components of such systems, being sensors,
actuators, controUed plants or entire strucutures. The common
feature of these approaches is the intention to detect an abrupt
change in some characteristic property of the considered object, by
monitoring the behavior of the system. This change may be a
slow-evolving effect or a complete breakdoWD. In tbis sense, fault
monitoring touches upon, and occasionaUy overIaps with, other areas
of control engineering such as adaptive control, robust controller
design, reIiabiIity and safety engineering, ergonomics and
man-macbine interfacing, etc. In fact, a system safety problem,
could be attacked from any of the above angles of view. In tbis
book, we don't touch upon these areas, unless there is a strong
relationship between the fauIt monitoring approaches discussed and
the aforementioned fields. When we set out to write tbis book, our
aim was to incIude as much material as possible in a most rigorous,
unified and concise format. Tbis would incIude state-of-the-art
method as weil as more cIassical techniques, stilI in use today. AB
we proceeded in gathering material, however, it soon became
apparent that these were contradicting design criteria and a
trade-off had to be made. We believe that the completeness vs.
Comprising specially selected papers on the subject of
Computational Methods and Experimental Measurements, this book
includes research from scientists, researchers and specialists who
perform experiments, develop computer codes and carry out
measurements on prototypes. Improvements relating to computational
methods have generated an ever-increasing expansion of
computational simulations that permeate all fields of science and
technology. Validating the results of these improvements can be
achieved by carrying out committed and accurate experiments, which
have undertaken continuous development. Current experimental
techniques have become more complex and sophisticated so that they
require the intensive use of computers, both for running
experiments as well as acquiring and processing the resulting data.
This title explores new experimental and computational methods and
covers various topics such as: Computer-aided Models; Image
Analysis Applications; Noise Filtration of Shockwave Propagation;
Finite Element Simulations.
This book highlights the application of Time-of-Flight Secondary
Ion Mass Spectrometry (ToF-SIMS) for high-resolution surface
analysis and characterization of materials. While providing a brief
overview of the principles of SIMS, it also provides examples of
how dual-beam ToF-SIMS is used to investigate a range of materials
systems and properties. Over the years, SIMS instrumentation has
dramatically changed since the earliest secondary ion mass
spectrometers were first developed. Instruments were once dedicated
to either the depth profiling of materials using high-ion-beam
currents to analyse near surface to bulk regions of materials
(dynamic SIMS), or time-of-flight instruments that produced complex
mass spectra of the very outer-most surface of samples, using very
low-beam currents (static SIMS). Now, with the development of
dual-beam instruments these two very distinct fields now overlap.
The world of artificial systems is reaching hitherto undreamed-of levels of complexity. Surface traffic, electricity distribution, mobile communications, etc., demonstrate that problems are arising that are beyond classical scientific or engineering knowledge. In order that our ability to control such systems should not be hindered by lack of comprehension, there is an on-going effort to understand them.This book is an example of the types of approach that European researchers are using to tackle problems derived from systems' complexity. It has grown out of activities in the Control of Complex Systems (COSY) research program the goals of which are to promote multi-disciplinary activity leading to a deeper understanding and further development of control technologies for complex systems and if possible, to develop the theory underlying such systems. The material in this book represents a selection of the results of the COSY program and is organised as a collection of essays of varying nature: surveys of essential areas, discussion of specific problems, case studies, and benchmark problems.Topics covered include:Modelling complex physical systems;Passivity-based control of non-linear systems;Aspects of fault identification and fault tolerance;Control design;Learning control;Satellite attitude control.Complex systems appear in many different fields and for this reason this book should be of interest to scientists, researchers and industrial engineers with a broad spectrum of experience.
Measurement is an essential activity in every branch of technology
and science, the fourth edition of this successful text has been
extensively extended and updated to include new developments in
measurement devices and technology. Principles of Measurement
Systems, 4/e provides a coherent and integrated approach to the
topic, covering the main techniques and devices used, together with
relevant theory applications, for both mechanical and electronic
systems.
