Over the years, the electric power industry has been using
optimization methods to help them solve the unit commitment
problem. The result has been savings of tens and perhaps hundreds
of millions of dollars in fuel costs. Things are changing, however.
Optimization technology is improving, and the industry is
undergoing radical restructuring. Consequently, the role of
commitment models is changing, and the value of the improved
solutions that better algorithms might yield is increasing. The
dual purpose of this book is to explore the technology and needs of
the next generation of computer models for aiding unit commitment
decisions. Because of the unit commitment problem's size and
complexity and because of the large economic benefits that could
result from its improved solution, considerable attention has been
devoted to algorithm development in the book. More systematic
procedures based on a variety of widely researched algorithms have
been proposed and tested. These techniques have included dynamic
programming, branch-and-bound mixed integer programming (MIP),
linear and network programming approaches, and Benders
decomposition methods, among others. Recently, metaheuristic
methods have been tested, such as genetic programming and simulated
annealing, along with expert systems and neural networks. Because
electric markets are changing rapidly, how UC models are solved and
what purposes they serve need reconsideration. Hence, the book
brings together people who understand the problem and people who
know what improvements in algorithms are really possible. The
two-fold result in The Next Generation of Electric Power Unit
Commitment Models is an assessment of industry needs and new
formulations and computational approaches that promise to make unit
commitment models more responsive to those needs.
For centuries, African and Irish people have traversed the
Atlantic, as slaves, servants, migrants, exiles, political
organizers and cultural workers. Their experiences intersected;
their cultures influenced one another. These essays explore the
connections that have defined the 'Black and Green Atlantic' in
culture, politics, race and labour.
From reviews of the previous edition
"The island nation of Trinidad and Tobago has long served as a
window on South American birdlife. Birders have been visiting the
two islands in large numbers since the 1960s, when Asa Wright
converted an unproductive plantation into one of the first
neotropical 'ecotourist traps.' Anyone traveling to Trinidad and
Tobago shouldn't leave home without this work." Journal of Field
Ornithology
"This book will be wanted by any birder visiting Trinidad and
Tobago, as well as by many ornithologists as a general reference."
Wilson Bulletin
Members of nearly all the families of South American birds can
be found on the two beautiful West Indian islands of Trinidad and
Tobago, where the pleasant climate, varied habitat, and avian
diversity create a "birder's paradise." This easy-to-use book is
the third edition of a comprehensive yet compact field guide to all
477 species of the islands' birds, including 35 new species
accounts added to the country's bird list since the last edition.
Richard ffrench s work has been a "bible" to birders since the
appearance of the first edition in 1973. This new edition
incorporates five decades of his notes and records of the island s
birds to present in a handy and readable form detailed and
comprehensive information about the birds of Trinidad and
Tobago.
Showcasing 40 all-new color plates by the very best bird artists
working under the direction of John P. O Neill, the third edition
now includes illustrations of not only the islands endemic and
resident species, but also the many migratory species that visit
the islands from both the north and the south. The taxonomic
arrangement and treatment of families and species has also been
brought in line with the most recent determinations of the A.O.U.
Committee on Nomenclature for a thoroughly up-to-date presentation.
In his introduction, Richard ffrench offers a full treatment of the
history of ornithology in Trinidad and Tobago and sets the scene by
describing the islands physiography, climate, and vegetation.
Individual species accounts, arranged by family, make up the core
of this identification guide. The accounts cover habitat and
status, range and subspecies, field description and basic
measurements, voice, food, nesting, and behavior. Richard ffrench s
summary of the distribution of species and their breeding and
migration, as well as local conservation and protection measures,
makes this volume much more than a typical field-guide treatment,
and invites visitors to this premier ecotourism destination."

With over 1800 species, Peru has the second richest avifauna of any
country in the world. As a consequence it is one of the most
popular birding destinations in South America. This will be the
first comprehensive and fully illustrated field guide to the birds
of Peru. Text is arranged opposite the plates, in conventional
field guide manner. The combination of authoritative text and
superb artwork will set new standards for South American field
guides.

Interest in the biological effects of ionising radiation closely
followed the identification of such radiation. The realisation that
DNA is the site of genetic infonnation in cells subsequently
focussed attention on DNA as an important target in the lethal and
mutagenic effects of ionising radiation. Thus radiation effects
upon DNA became an important area for fundamental scientific
studies by radiation biologists, chemists and physicists. To a
first approximation, the concerns of the three disciplines can be
divided by time scales: the physical process of energy deposition
from photon or charged 16 12 particle and subsequent relaxation
(-10- to 10- secs), followed by chemical 12 2 reactions (- 10- to
10 secs), and fmally, the expression of biological effect (minutes
to years). Thus, the concept of 'early processes' conveys different
ideas to different scientists, although they are all interrelated.
To attempt to describe in any detail all these processes is a
mammoth task which is not made easier by the different conventions
and experimental approaches of the three disciplines. However, the
recent advances in all these scientific areas seemed, to the
organisers at least, to offer the opportunity to stimulate more
active interaction between physicists, chemists and biologists.
With this in mind, a multi-disciplinary workshop was organised,
which brought together some fifty scientists to present their own
specialist interests and, through extensive discussion, explore
which problems are of high priority and require input from the
different disciplines to resolve them.
Birds of Peru is the most complete and authoritative field guide to
this diverse, neotropical landscape. It features every one of
Peru's 1,817 bird species and shows the distinct plumages of each
in 307 superb, high-quality color plates. Concise descriptions and
color distribution maps are located opposite the plates, making
this book much easier to use in the field than standard neotropical
field guides. This fully revised paperback edition includes
twenty-five additional species. * A comprehensive guide to all
1,817 species found in Peru--one fifth of the world's birds--with
subspecies, sexes, age classes, and morphs fully illustrated *
Designed especially for field use, with vivid descriptive
information and helpful identification tips opposite color plates *
Detailed species accounts, including a full-color distribution map
* Includes 25 additional species not covered in the first edition *
Features 3 entirely new plates and more than 25 additional
illustrations
