This CD-ROM dictionary comprises both volumes of the 6th print
edition of the "Dictionary of Electrical Engineering, Power
Engineering and Automation." For this edition, the
worldwide-respected dictionary has been updated and enlarged by
about 40%. It is the standard work for all those requiring a
comprehensive and reliable compilation of terms from the fields of
power generation, transmission and distribution, drive engineering,
automation, switchgear and installation engineering, power
electronics as well as measurement, analysis and test engineering.
Including also a great number of basic electrotechnical terms, with
about 121,000 entries and 166,000 translations in German-English
and 115,000 entries and 156,000 translations in English-German it
comprehensively covers large fields of industrially applied
electrical engineering.

This expanded, revised and updated new edition of Introduction to
RF Stealth covers two major topics: Low Observables and Low
Probability of Intercept (LO and LPI) of radars and data links,
collectively sometimes called Stealth. Each chapter includes
examples, student exercises and references. Worked simulations are
available that illustrate the techniques described. Chapter 1
provides an introduction and history of RF/microwave LPI/LO
techniques and some basic LPI/LO equations, expanded from the first
edition with more information on new and current systems, including
more on infrared and hypersonic missile signatures. Chapter 2 is a
new chapter, covering radiation absorbing materials and shaping,
focused on materials, meta-materials and detailed platform shaping
and structures including ships. Chapter 3 covers interceptability
parameters and analysis with corrections, updates and simulations.
Chapter 4 covers current and future intercept receivers and some of
their limitations with more information and tracking techniques.
Chapter 5 surveys exploitation of both the natural and the threat
environment with extensive threat table updates including Russian
S300, S400, S500 and more information on cellular systems. Chapter
6 deals with LPIS waveforms and pulse compression with new material
and simulations of new codes. Chapter 7 introduces some hardware
techniques associated with LO/LPIS low sidelobe / cross section
antenna and radome design with emphasis on active electronic scan
arrays. Chapter 8 is a new chapter on RCS testing of subsystems and
platforms.
When our smartphones distract us, much more is at stake than a
momentary lapse of attention. Our use of smartphones can interfere
with the building-blocks of meaningfulness and the actions that
shape our self-identity. By analyzing social interactions and
evolving experiences, Roholt reveals the mechanisms of
smartphone-distraction that impact our meaningful projects and
activities. Roholt's conception of meaning in life draws from a
disparate group of philosophers - Susan Wolf, John Dewey, Hubert
Dreyfus, Martin Heidegger, and Albert Borgmann. Central to Roholt's
argument are what Borgmann calls focal practices: dinners with
friends, running, a college seminar, attending sporting events. As
a recurring example, Roholt develops the classification of musical
instruments as focal things, contending that musical performance
can be fruitfully understood as a focal practice. Through this
exploration of what generates meaning in life, Roholt makes us
rethink the place we allow smartphones to occupy in the everyday.
But he remains cautiously optimistic. This thoughtful, needed
interrogation of smartphones shows how we can establish a positive
role for technologies within our lives.
This is an account of the author's investigation, on behalf of the
Canadian government, into the life and ideas of the eccentric
genius Nikola Tesla. This is a completely revised and redesigned
edition, with a new introduction by the former head of the Tesla
Museum, a new chapter and a selection of photographs of Tesla and
his work in search of the holy grail of electricity - the
transmission of power without loss. As a student in Prague in the
1870s, Tesla "saw" the electric induction motor and patented his
discovery, -the first of many inventions whose plans seem to have
come to him fully fledged. He worked for the Edison company in
Paris before emigrating to the US and battling with Thomas Edison
himself to ensure that alternating, rather than direct current,
became the standard. He sold his patent in the induction motor for
$1 million dollars to George Westinghouse, who used this system for
the Niagara Falls Power Project. Moving to Colorado Springs, Tesla
worked on resonance, building enormous oscillating towers in
experiments which still intrigue today. In later life Tesla became
a recluse, bombarding newspapers with eccentric claims, including
energy transmissions to other planets. Though he died alone and
virtually forgotten, rumours gradually grew that Tesla had made
further remarkable discoveries. In an attempt to replicate his
experiments, people still build Tesla towers and puzzle over the
possible link with low-frequency broadcasts which can supposedly
disrupt the weather and affect the human mind.
Discover the most recent advances in electromagnetic vortices In
Electromagnetic Vortices: Wave Phenomena and Engineering
Applications, a team of distinguished researchers delivers a
cutting-edge treatment of electromagnetic vortex waves, including
their theoretical foundation, related wave properties, and several
potentially transformative applications. The book is divided into
three parts. The editors first include resources that describe the
generation, sorting, and manipulation of vortex waves, as well as
descriptions of interesting wave behavior in the infrared and
optical regimes with custom-designed nanostructures. They then
discuss the generation, multiplexing, and propagation of vortex
waves at the microwave and millimeter-wave frequencies. Finally,
the selected contributions discuss several representative practical
applications of vortex waves from a system perspective. With
coverage that incorporates demonstration examples from a wide range
of related sub-areas, this essential edited volume also offers:
Thorough introductions to the generation of optical vortex beams
and transformation optical vortex wave synthesizers Comprehensive
explorations of millimeter-wave metasurfaces for high-capacity and
broadband generation of vector vortex beams, as well as orbital
angular momentum (OAM) detection and its observation in second
harmonic generations Practical discussions of microwave SPP
circuits and coding metasurfaces for vortex beam generation and
OAM-based structured radio beams and their applications In-depth
examinations and explorations of OAM multiplexing for wireless
communications, wireless power transmission, as well as quantum
communications and simulations Perfect for students of wireless
communications, antenna/RF design, optical communications, and
nanophotonics, Electromagnetic Vortices: Wave Phenomena and
Engineering Applications is also an indispensable resource for
researchers in academia, at large defense contractors, and in
government labs.
