A comprehensive reference and guide on the usage of the alternative
dielectric fluids for transformer insulation systems Liquid-filled
transformers are one of the most important and expensive components
involved in the transmission and distribution of power to
industrial and domestic loads. Although petroleum-based insulating
oils have been used in transformers for decades, recent
environmental concerns, health and safety considerations, and
various technical factors have increased the need for new
alternative and biodegradable liquids. Alternative Liquid
Dielectrics for High Voltage Transformer Insulation Systems is an
up-to-date reference and guide on natural and synthetic ester-based
biodegradable insulating liquids. Covering the operational
behavior, performance analysis, and maintenance of transformers
filled with biodegradable insulating liquids, this comprehensive
resource helps researchers and utility engineers expand their
knowledge of the benefits, challenges, and application of
ester-filled transformers. In-depth chapters written by experienced
researchers addresses critical topics including transformer
condition monitoring, high voltage insulation testing,
biodegradable insulating material processing and evaluation, and
more. A unique and significant contribution to existing literature
on the subject, this authoritative volume: - Covers condition
monitoring, diagnostic testing, applications, maintenance, and
in-service experiences - Explores current challenges and future
prospects of ester-filled transformers - Discusses significant
research progress and identifies the topics in need of further
emphasis - Compares the differences and similarities between
mineral oils and ester liquids - Includes in-depth behavioral
observations and performance analysis of ester-based insulating
liquids Alternative Liquid Dielectrics for High Voltage Transformer
Insulation Systems: Performance Analysis and Applications is a
must-have reference for utility engineers, electrical power
utilities, transformer owners, manufacturers, and researchers.
This is the revised and enlarged 2nd edition of the authors'
original text, which was intended to be a modest complement to
Grenander's fundamental memoir on stochastic processes and related
inference theory. The present volume gives a substantial account of
regression analysis, both for stochastic processes and measures,
and includes recent material on Ridge regression with some
unexpected applications, for example in econometrics. The first
three chapters can be used for a quarter or semester graduate
course on inference on stochastic processes. The remaining chapters
provide more advanced material on stochastic analysis suitable for
graduate seminars and discussions, leading to dissertation or
research work. In general, the book will be of interest to
researchers in probability theory, mathematical statistics and
electrical and information theory.
This proceedings volume contains 66 papers presented at the second
"Contact Mechanics International Symposium" held in Carry-Le-Rouet.
France. from September 19th to 23rd. 1994, attended by 110
participants from 17 countries. This symposium was the continuation
of the first CMIS held in 1992 in Lausanne. of the Symposium
Euromech 273 "Unilateral Contact and Dry Friction" held in 1990 in
La Grande Motte. France. and of the series of "Meetings on
Unilateral Problems in Structural Analysis" organized in Italy.
every other year. during the eighties. The primary purpose of the
symposium was to bring specialists of contact mechanics together in
order to draw a representative picture of the state of the art and
to identify new trends and new features in the field. In view of
the contributions made. one may assert that the mechanics of
contact and friction has now reached a stage where the foundations
are clear both from the mathematical and from the computational
standpoints. Some of the difficulties met may be identified by
saying that frictional contact is governed by resistance laws that
are non smooth and whose flow rule is not associated with the yield
criterion through the traditional normality property.
Fullerene Polymers and Fullerene Polymer Composites is an in-depth
experimental and theoretical account of polymers and composites
whose unusual properties, such as, photophysical phenomena,
electrical transport, phase transitions and magnetic properties,
stem from the incorporation of C60 in the material. Each chapter is
written by an internationally renowned expert who has published
extensively in this sub-field of fullerene materials. Introductory
chapters on the fundamental properties of fullerenes (C60, C70) and
photophysical phenomena in fullerenes and polymers are also
included.
This is a revised and expanded edition of a successful graduate
and reference text. The book is designed for a standard graduate
course on probability theory, including some important
applications. The new edition offers a detailed treatment of the
core area of probability, and both structural and limit results are
presented in detail. Compared to the first edition, the material
and presentation are better highlighted; each chapter is improved
and updated.
Stochastic Processes: General Theory starts with the fundamental
existence theorem of Kolmogorov, together with several of its
extensions to stochastic processes. It treats the function
theoretical aspects of processes and includes an extended account
of martingales and their generalizations. Various compositions of
(quasi- or semi-)martingales and their integrals are given. Here
the Bochner boundedness principle plays a unifying role: a unique
feature of the book. Applications to higher order stochastic
differential equations and their special features are presented in
detail. Stochastic processes in a manifold and multiparameter
stochastic analysis are also discussed. Each of the seven chapters
includes complements, exercises and extensive references: many
avenues of research are suggested. The book is a completely revised
and enlarged version of the author's Stochastic Processes and
Integration (Noordhoff, 1979). The new title reflects the content
and generality of the extensive amount of new material. Audience:
Suitable as a text/reference for second year graduate classes and
seminars. A knowledge of real analysis, including Lebesgue
integration, is a prerequisite.

The material accumulated and presented in this volume can be ex
plained easily. At the start of my graduate studies in the early
1950s, I Grenander's (1950) thesis, and was much attracted to the
came across entire subject considered there. I then began preparing
for the neces sary mathematics to appreciate and possibly make some
contributions to the area. Thus after a decade of learning and some
publications on the way, I wanted to write a modest monograph
complementing Grenander's fundamental memoir. So I took a
sabbatical leave from my teaching position at the Carnegie-Mellon
University, encouraged by an Air Force Grant for the purpose, and
followed by a couple of years more learning opportunity at the
Institute for Advanced Study to complete the project. As I
progressed, the plan grew larger needing a substantial background
material which was made into an independent initial volume in
(1979). In its preface I said: "My intension was to present the
following material as the first part of a book treating the In
ference Theory of stochastic processes, but the latter account has
now receded to a distant future," namely for two more decades
Meanwhile, a much enlarged second edition of that early work has
appeared (1995), and now I am able to present the main part of the
original plan."

Intelligent Manufacturing is a new disciplinary field which applies
computer science, artificial intelligence, mechanical engineering
and systems science to industrial manufacturing processes. This
book presents a new integration architecture for implementing
real-time distributed intelligent manufacturing systems.
The book addresses instability and bifurcation phenomena in frictional contact problems. The treatment of this subject has its roots in previous studies of instability and bifurcation in elastic, thermoelastic or elastic-plastic bodies, and in previous mathematical, mechanical and computational studies of unilateral problems. The salient feature of this book is to put together and develop concepts and tools for stability and bifurcation studies in mechanics, taking into account the inherent non-smoothness and non-associativity (non-symmetry) of unilateral frictional contact laws. The mechanical foundations, the mathematical theory and the computational algorithms for such studies are developed along six chapters written by the lecturers of a CISM course. Those concepts and tools are illustrated not only with enlightening academic examples but also with some demanding industrial applications, related, namely, to the automotive industry.

Reactive dyes containing diazo bonds are more resistant to
anaerobic reduction in comparison to monoazo dyes. Reactive
Yellow-145 (RY-145) which is used as a model dye is a diazo dye
having -SO3H group in its structure. A novel bacterial consortium
was isolated from the soil samples of a local dye manufacturing
unit at Ahmedabad, Gujarat, India. This culture was used for
decolorization parametric study of RY-145 under various operating
conditions. The consortium was successfully able to decolorize, 300
mg l-1 of selected dye up to 97% within 11 h under static
facultative conditions at pH 7.0 and 37 C temperature. The UV -
Visible Spectroscopic analysis results indicate the decolorization
of dye. The HPLC and FTIR results confirm degradation of RY-145
into smaller compounds. For the commercial viability, combination
of specially prepared synthetic medium and extract of agriculture
waste is used as a growth medium for consortium in place of
nutrient broth. COD reduction of nearly 70% is achieved for 20
times diluted industrial wastewater. Specially designed continuous
column reactor (PMSCCR) has also been used for batch and continuous
study of decolorization of RY-145.
