The rapid technological developments during the later half of the
20th century have demanded materials that are stronger, capable of
use at much higher temperatures, more corrosion-resistant, and much
less expensive than those currently used. These demands become even
more significant on the threshold of the new century and the
millennium. Significant improvements in properties can only be
achieved by processing the materials under far-from-equilibrium (or
non-equilibrium) conditions. Several new processing technologies
have been developed during the past few decades including, rapid
solidification, spray forming, mechanical alloying, ion mixing,
vapor deposition, laser processing and plasma processing. Remarkable advances have been made in recent years in the
science and technology of these processes used to synthesize,
characterize, and apply these materials processed under
non-equilibrium conditions. Some of these techniques have evolved
from laboratory curiosity to commercial-scale manufacturing in just
a few years. In other cases, industrial necessity prompted
development of the technology, and the science followed
later. The chapters in this book have been written by people who are
world-recognized experts in their respective fields. Each chapter
describes the principles, processing techniques, special features
of the materials produced, and their applications. An extensive
list of references is provided at the end of each chapter that will
facilitate location of additional information on specific aspects
of any technique.
The ESIS-Technical Committee 9 on Concrete was established in 1990
and has met seven times. A proposal was put to European and
extra-European laboratories entitled "Scale effects and
transitional failure phenomena of reinforced concrete beams in
flexure" which lead to several positive responses. The central topic discussed by the committee was that of the
minimum reinforcement in concrete members. The minimum amount of
reinforcement is defined as that for which "peak load at first
concrete cracking" and "ultimate load after steel yielding" are
equal. In this way, any brittle behaviour is avoided as well as any
localized failure, if the member is not over-reinforced. In other
words, there is a reinforcement percentage range, depending on the
size-scale, within which the plastic limit analysis may be applied
with its static and kinematic theorems. Carpinteri, Ferro, Bosco and El-Katieb propose a LEFM model,
according to which reinforcement reactions are applied directly on
the crack surfaces and a compatibility condition is locally imposed
on the crack opening displacement in correspondence with the
reinforcement. The theoretical model is found to provide a
satisfactory estimate of the minimum percentage of reinforcement
that depends on the scale and enables the element in flexure to
prevent brittle failure.
The objective of this publication is to comprehensively discuss the possibilities of producing steels with pre-determined attributes, demanded by the customer to fit exacting specifications. The information presented in the book has been designed to indicate the reasons for the expenses and to aid in the process of overcoming the difficulties and reducing the costs.
These proceedings contain the papers presented at the 4th
International Symposium on Engineering Turbulence Modelling and
Measurements held at Ajaccio, Corsica, France from 24-26 May 1999.
It follows three previous conferences on the topic of engineering
turbulence modelling and measurements.
As plastics are being used more extensively in high-performance markets, it is imperative that designers and engineers understand all aspects of polymer behavior over an extended service life. Dynamic Mechanical Analysis for Plastics Engineering describes practical uses for DMA information. All of the information for 120 families of thermoplastics is based on independent test data conducted exclusively for this product and is not available through any other source. This PDL addition shows how to use the DMA data to predict, at various temperatures, each materials estimated service life and potential for failure. This book explains the correlation between time and temperature-dependence and illustrates how time-dependent responses such as creep and stress relaxation affect the practical utility of different materials. Basic polymer structures are discussed and test results show how these structural details can be detected and understood.
ICSAS '99 - The Fourth International Conference on Steel and
Aluminium Structures was a sequel to ICSAS '87 held in Cardiff, UK,
to ICSAS '91 held in Singapore and to ICSAS '95 held in Istanbul,
Turkey. The objective of the conference was to provide a forum for
the discussion of recent findings and developments in the design
and construction of various types of steel and aluminium
structures. The conference was concerned with the analysis, modelling and
design of light-weight or slender structures in which the primary
material is structural steel, stainless or aluminium. The
structural analysis papers presented at the conference cover both
static and dynamic behaviour, instability behaviour and long-term
behaviour under hygrothermal effects. The results of the latest
research and development of some new structural products were also
presented at the conference. A total of 76 papers and 30 posters
were presented at the conference by participants from 36 countries
in all 6 continents.
This collection of 185 papers results from contributions made at
Electroceramics VI which forms part of the joint triple meeting
held in Montreaux, Switzerland in August 1998. The joint meeting
covered recent advances in the broad and rapidly progressing field
of electroceramics, ferroelectrics and polar dielectrics. More than
550 papers were presented at the triple meeting (250 of them at
Electorceramics VI '98) including a series of plenary lectures
highlighting research areas of strong current and emerging
interests. The meeting demonstrated the wide variety of new
applications being developed, based in particular on
ferroelectrics, polar dielectrics, ionic conductors and any other
functional ceramics. In comparison with previous meetings, the present one showed the growing importance of surfaces, interfaces and other boundaries, e.g. domain walls. Size effects and questions related to nanotechnology were comprehensively discussed both on the academic level and for device realizations. Microdevices and their integration problems (and solutions) were at the heart of many reports. The papers reflected the extensive activities in this interdisciplinary area, while the balance between presentations from academic laboratories and from industrial R&D laboratories was a testimony to its vitality. The volume contains 185 papers selected after refereeing of the 220 papers submitted for publication.
The sea is steadily rising, presently at 3.4 mm per year, and it is already costing billions in Venice, on the Thames river and in New York City, to counter sea-level-related surges. Experts anticipate an accelerated rise, and credible predictions for sea-level rise by the year 2100 range from 12 inches to above six feet. Study of the Earth's geologic history, through ice-core samples, links sea-level rise to temperature rise. Since the lifetime of carbon dioxide in the atmosphere is measured in centuries, and it has upset the balance of incoming and outgoing energy, the Earth's temperature will continue to rise, even if carbon burning ceases. Engineering the Earth's solar input appears increasingly attractive and practical as a means to lower the Earth's temperature and, thus, to lower the sea level. The cost of engineering the climate appears small; comparable, even, to the already-incurred costs of sea-level rise represented by civil engineering projects in London, Venice and New York City. Feasible deployment of geoengineering, accompanied by some reduction in carbon burning, is predicted to lower the sea level by the order of one foot by 2100, which negates the expected rise and would provide an immense economic benefit. The accompanying lower global temperature would reduce the severity of extreme weather and restore habitability to lethally hot parts of the world.
The progress in device technologies are surveyed in this volume. Included are Si/ (Si-Ge) heterojunctions for high-speed integrated circuits. Schottky-barrier arrays in Si and Si-Ge alloys for infrared imaging, III-V quantum-well detector structures operated in the heterodyne mode for high-data-rate communications, and III-V heterostructures and quantum-wells for infrared transmissions.
While research on ultrasonics has been covered in earlier volumes
of the Physical Acoustics series, Volumes 23 and 24 demonstrate the
successful commercialization of devices and instruments arising
from research in this area. These volumes will assist in the
process of bringing research output into the marketplace to the
benefit of customers.
The previous edition of Ship Design for Efficiency and Economy was published as a Butterworth's marine engineering title. It has now been completely revised and updated by Schneekluth and Bertram. This book gives advice to students and naval architects on how
to design ships - in particular with regard to hull design. The
previous edition of this book was published in 1987. Since then,
there have been numerous important developments in this area and
the new additions to this book reflect these changes. Chapter 3 has
been completely rewritten with added information on methodology of
optimization, optimization shells and concept exploration methods.
There is also a new sub-chapter on Computational Fluid Dynamics
(CFD) for ship-hull design. Plus, a new method to predict ship
resistance based on the evaluation of modern ship hull design will
be detailed.
This book examines the physical testing of textiles in the form of fibre, yarn and fabric, the emphasis throughout eing on standard and reproducible tests. After an introductory explanation of sampling and measurement, the author explores the effects of moisture on textiles, then goes on to discuss fibre dimension, yarn tests for linear density, twist, evenness and hairiness, tensile strength, and dimensional stability and serviceability. Also covered are aspects of comfort and fabric handle, colour fastness and quality assurance. The book's comprehensive coverage of the physical properties of textiles makes it an essential reference for managers in the textiles industry concerned with quality assurance, garment and fabric technologists, and students of textile science and engineering.
The symposium brought together more than a hundred attendees from
many countries including a significant participation from Japan and
other East-Asia countries. Many of the trends observed in the 1st
Symposium held in 1996 were confirmed: displays are indeed the main
application in LAE (photovoltaics were not included in the topics
of this symposium) and active matrix display (AMLCD) is still the
leading technology. Future AMLCDs integrating the display drivers
onto the same substrate require much faster thin-film transistors
(TFTs) than those used for LCD addressing, therefore putting a
strong demand on polysilicon performances. As a consequence the
quest for an improved low temperature, large area (and low cost)
polysilicon process is intensive and the competitors, including
direct plasma deposition and excimer laser crystallization of
amorphous layers, are reporting significant steps forward. With the
tremendous demand for efficient colour flat panel displays, other
display technologies are gaining interest. Field emission display
(FED) is one of them. FEDs based on amorphous tetrahedral carbon
thin-films are stimulating intensive studies on the optoelectronic
properties of this complex material.
These proceedings contain the reviewed papers presented at the
Symposium J on "Ion Implantation into Semiconductors, Oxides and
Ceramics," which was held at the Spring Meeting of the European
Materials Research Society in Strasbourg, France, 16-19, June 1998.
The symposium attracted 110 contributions, with authors from 31
nations in 5 continents. It was thereby the largest in a series of
E-MRS ion beam symposia, documenting the importance of ion beam
techniques and research in this area.
Jointly hosted by the Ergonomics Society of South Africa (ESSA) and
the International Ergonomics Association (IEA), this conference was
attended by over 300 delegates and represented the largest and most
prestigious gathering of eminent international ergonomists in the
history of Africa. It also marked the beginning of a revival in
concern for the well-being and productivity of people at work in
South Africa. The conference aimed to juxtapose two great ergonomic themes the
under-developed ethos of the affluent societies and the
technologically advanced ethos of the most affluent societies. The
structure of the proceedings reflects this with the first section
addressing the priorities of countries in transition and the last
section addressing the priorities of the most
industrially-developed countries, who have, by and large, long
since solved the sorts of ergonomics problems currently of concern
in the under-developed world. In between these, in a roughly
hierarchical arrangement from micro- to macro- levels of analysis,
are sections which collectively help span the whole field of
ergonomics. Section overviews are provided to outline the topics
included in each section.
Laboratory Methods in Food Microbiology describes a wide range of
methods for use in the microbiological analysis of foods, including
approaches to counting and detection procedures for microorganisms,
identification of bacteria, yeasts and fungi, microbiological
analysis for the main food commodity groups, and safety in the food
microbiology laboratory. The book also discusses specific food
poisoning outbreaks in the United States.
Electrostatic accelerators have been at the forefront of modern technology since 1932, when Sir John Cockroft and Ernest Walton developed the first accelerator. Although the electrostatic accelerator field is more than 90 years old, the field and the number of accelerators is growing more rapidly than ever. This book provides an overview of the basic science and technology that underlies the electrostatic accelerator field so it can serve as a reference guide and textbook for accelerator engineers as well as students and researchers who work with electrostatic accelerators.
Over the last several years, the four authors have jointly
conducted research into the analysis of vibrating Mindlin plates as
a collaborative project between Nanyang Technological University,
The National University of Singapore, and The University of
Queensland. The research was prompted by the fact that there is a
dearth of vibration results for Mindlin plates when compared to
classical thin plate solutions. To generate the vibration results,
the authors have successfully employed the Ritz method for general
plate shapes and boundary conditions. The Ritz method, once thought
to be awkward for general plate analysis, can be automated through
suitable trial functions (for displacements) that satisfy the
geometric plate boundary conditions "a priori." This work has been
well-received by academics and researchers, as indicated by the
continual requests for the authors' papers and the Ritz software
codes. This monograph is written with the view to share this
so-called "p"-Ritz method for the vibration analysis of Mindlin
plates and its software codes with the research community. To the
authors' knowledge, the monograph contains the first published Ritz
plate software codes of its kind.
Vintage Radio, Television and Hi-Fi are highly popular 'modern
antiques' - and offer the added challenge for restorers of the
repair of classic valve-based circuits. This highly readable book
encompasses all aspects of buying, collecting, restoring,
repairing, sourcing parts, professional services, clubs and
societies, etc. Covering the technical side as well as collecting,
this book offers the most comprehensive coverage available. The first half of the book deals primarily with technical
aspects of restoration, what components are needed and where they
can be found. The second half of the book provides a wealth of
useful information: names and addresses of clubs and societies,
auctions and antique fairs; a professional services directory; how
to get hold of service data. Armed with this book the enthusiast
will be able to tackle the restoration of a vintage machine with
confidence.
The ever-growing demand for commercial activities at sea has meant
that ships are rapidly developing and that the rules governing
their construction and operation are changing. "Practical Ship
Design" records these changes, their outcomes and the reasoning
behind them. It deals with every aspect of ship design and handles a wide
range of both merchant ships and naval ships with authority. It
provides coverage of cargo ships and passenger ships, tugs,
dredgers and other service craft. It also includes concept design,
detail design, structural design, hydrodynamics design, the effect
of regulations, the preparation of specifications and matters of
costs and economics. Drawing on the author's extensive practical experience,
"Practical Ship Design" is likely to interest everybody involved in
the design, construction, repair and operation of ships. Students
and the most experienced professionals will all benefit from the
book's vast store of design data and its conclusions and
recommendations.
While research on ultrasonics has been covered in earlier volumes
of the Physical Acoustics series, Volumes 23 and 24 demonstrate the
successful commercialization of devices and instruments arising
from research in this area. These volumes will assist in the
process of bringing research output into the marketplace to the
benefit of customers.
These two volumes contain the Proceedings of the 9th IFAC symposium
on Information Control in Manufacturing which took place in Nancy
and Metz, France, between 24-26 June, 1998.
The two volumes contain the Proceedings of the 5th IFAC DYCOPS
Symposium that took place in Corfu, Greece between June 8-10, 1998.
The Symposium was a continuation of the very successful series that
used to be called DYCORD+, the last of which (DYCORD+ '95) took
place in Denmark in 1995. It was sponsored by the IFAC Technical
Committee on Chemical Process Control.
Thin-plated structures are used extensively in building
construction, automobile, aircraft, shipbuilding and other
industries because of a number of favourable factors such as high
strength-weight ratio, development of new materials and processes
and the availability of efficient analytical methods. This class of
structure is made by joining thin plates together at their edges
and they rely for their rigidity and strength upon the tremendous
stiffness and load-carrying capacity of the flat plates from which
they are made. Many of the problems encountered in these structures
arise because of the effects of local buckling. The knowledge of
various facets of this phenomenon has increased dramatically since
the 1960s. Problem areas which were hitherto either too complex for
rigorous analysis or whose subtleties were not fully realized have
in these years been subjected to intensive study. Great advances
have been made in the areas of inelastic buckling. The growth in
use of lightweight strong materials, such as fibre-reinforced
plastics has also been a contributory factor towards the need for
advances in the knowledge of the far post-buckling range. The
conference is a sequel to the international conference organised by
the University of Strathclyde in December 1996 and this
international gathering will provide the opportunity for discussion
of recent developments and trends in design of thin-walled
structures.
Mechatronics, a synergistic combination of mechanical, electronic
and computing engineering technologies, is a truly
multidisciplinary approach to engineering. New products based on
mechatronic principles are demonstrating reduced mechanical
complexity, increased performance and often previously impossible
capabilities. This book contains the papers presented at the UK
Mechatronics Forum's 6th International Conference, held in Skovde,
Sweden, in September 1998. Many of these high-quality papers
illustrate the tremendous influence of mechatronics on such areas
as manufacturing machinery, automotive engineering, textiles
manufacture, robotics, and real-time control and vision systems.
There are also papers describing developments in sensors,
actuators, control and data processing techniques, such as fuzzy
logic and neural networks, all of which have practical application
to mechatronic systems. |
