Electrical steels are critical components of magnetic cores used in
applications ranging from large rotating machines, including energy
generating equipment, and transformers to small instrument
transformers and harmonic filters. Presented over two volumes, this
comprehensive handbook provides full coverage of the
state-of-the-art in electrical steels. Volume 2 describes
performance and outlines applications of electrical steels. Topics
covered include localised characteristics of electrical steels;
practical properties of electrical steels; other electrical steels;
prediction of losses in electrical steels; application of
electrical steels in transformer cores; applications of electrical
steels in rotating electrical machines; non-sinusoidal
magnetisation and applications; magnetic building factors in
electrical steel cores; use of amorphous ribbon and nano-materials
in transformer cores; electrical machine core vibration and noise;
approaches to predictions and measurements of flux density and loss
distributions in electrical machine cores; the application of
international standards to magnetic alloys and steels; electrical
steels and renewable energy systems; environmental impact of
electrical steels; and typical performance data of commercial
electrical steels. The companion Volume 1 covers the fundamentals
and basic concepts of electrical steels.

comprehensive handbook provides full coverage of the
state-of-the-art in electrical steels. Volume 1 covers the
fundamentals and basic concepts of electrical steels. Topics
covered include soft magnetic materials; basic magnetic concepts;
magnetic domains, energy minimisation and magnetostriction; methods
of observing magnetic domains in electrical steels; electromagnetic
induction; fundamentals of a.c. signals; losses and eddy currents
in soft magnetic materials; rotational magnetisation and losses;
anisotropy of iron and its alloys; magnetic circuits; the effect of
mechanical stress on loss, permeability and magnetostriction;
magnetic measurements on electrical steels; background to modern
electrical steels; production of electrical steels; amorphous and
nano-crystalline soft magnetic materials; nickel-iron, cobalt-iron
and aluminium-iron alloys; consolidated iron powder and ferrite
cores; and temperature and irradiation dependence of magnetic and
mechanical properties of soft magnetic materials. The companion
Volume 2 describes performance and outlines applications.
Any system for giving good advice has to maintain a tension between
telling the truth and not being heard, on the one hand, and telling
what can be heard but is not true, on the other. In such a system,
the role of academic researchers is not so much to give advice as
it is to generate knowledge and to provide critical commentary on
advice that is given. Along the way, an academic tries to
counteract the natural tendency of advice givers to become more
attentive to the hearing of their clients than to the knowledge
underlying what they say. This book is in that tradition. It honors
the noble tradition of giving advice on strategic management and
organizational learning by exploring some elements of fundamental
knowledge that might inform such advice.
Dave Adams is a teenager standing at a crossroads in his life. He's
lonely, a bully in need of direction. Through the pages of an
ancient, leather-bound journal, Dave makes contact with an
ancestor, James Adams, captain of a seventeenth century
sailing-ship. Captain Adams is also straddling a fence, and the
life of an honest sea-going merchant pales in comparison to the
excitement and opportunities available for a captain willing to do
what it takes to get ahead. Will the captain's decisions take him
and his crew where they want to go? And how will those decisions
affect Dave as he makes his way through high school and finds his
first summer job? "Pirate Journey" explores the parallel lives of a
scurvy sea captain and a high school bully as they make decisions
and face the consequences of their choices, both good and bad.
