These days, it is impossible to think of an area of knowledge that can keep on
developing without a collaboration in interdisciplinary fields.
Electromotive force is a type of energy per unit of electric charge that is converted
reversibly from chemical, mechanical, or other forms of energy into electrical energy
by a dynamo, battery, electrochemical cells, thermoelectric devices, solar cells,
transformers, and so on.
The theory of electromotive Force is currently one of the most important research
topics within the electrical engineering domain.
Tools shape how we think; when the only tool you have is an axe, everything resembles a
tree or a log. The rapid advances in instrumentation in the last decade, which allow us to
measure and manipulate individual molecules and structures on the nanoscale, have caused
a paradigm shift in the way we view molecular behavior and surfaces. The microscopic details
underlying interfacial phenomena have customarily been inferred from in situ measurements
of macroscopic quantities. Now we can see and “finger” physical and chemical
processes at interfaces.
With the advent of the atomic force microscope (AFM) came an extremely valuable
analytical resource and technique, useful for the qualitative and quantitative surface
analysis with sub-nanometer resolution. In addition, samples studied with an AFM do
not require any special pretreatments that may alter or damage the sample, and permit
a three dimensional investigation of the surface.
In this paper, a method to reproduce realistic
driving feeling and improve the returnability of steer-by-wire
systems (SBW) is proposed by measuring the roadwheel motor's
current directly. The key contribution presented here is a novel
method to recreate the driving feeling in term of force feedback
with simpie and cheap current sensors. A current sensor is used to
fully measure the steering torque on the rack of steering
mechanism. This measured steering torque therefore, includes the
overall effects of road conditions, aligning moments, tire
properties and so on.
Network Centric Warfare, the new paradigm of future warfighting, will produce increased amounts of information, and new tools will be needed to better utilize that information. With the increase in the flows of information, decisionmaking tools and processes from the strategic to the tactical level will allow force elements to be used more effectively during a campaign.
The immediate reason for the creation of this book has been the advent of Basel II.
This has forced many institutions with loan portfolios into building risk models, and,
as a consequence, a need has arisen to have these models validated both internally and
externally. What is surprising is that there is very little written that could guide consultants
in carrying out these validations. This book aims to fill that gap.
In everyday life we are often forced to make decisions involving risks and
perceived opportunities. The consequences of our decisions are affected by the
outcomes of random variables that are to various degrees beyond our control. Such
decision problems arise, for instance, in financial and insurance markets.
Satellite altimetry was developed in the 1960s soon after
the flight of artificial satellites became a reality. From the
vantage point in space, a radar altimeter is able to measure
the shape of the sea surface globally and frequently. Such
measurements have a wide range of applications to oceanography,
geodesy, and geophysics. The results are often revolutionary.
For example, in oceanography; it takes a ship weeks
or months to cross the ocean making measurements while
the ocean is constantly changing its circulation, temperature,

The first edition of the
Handbook of Micro/Nanotribology
was published in the Spring of 1995. Soon after
its publication, the first-of-a-kind monograph became a reference book for the novice, as well as experts,
in the emerging field of micro/nanotribology. Since the field is evolving very rapidly, we felt that the
monograph needed a second edition.
The second edition is totally revised. The scope of the first edition has been expanded. In the first
part, Basic Studies, two new chapters on AFM Instrumentation and Tips and Surface Forces and Adhesion
have been added.
Agriculture is also a significant source of economic growth. In developing countries,
agriculture generates on average 29 percent of the gross domestic product (GDP) and
employs 65 percent of the labour force. About two thirds of the world’s agricultural value
added is produced in developing countries. At the same time, agriculture also plays an
important role in transforming and urbanized economies, where industries and services
linked to agriculture account for more than 30 percent of GDP (ibid.).
Magnetism often has a slight overtone of being mysterious. This is probably
caused by the surprisingly strong forces between magnets which everybody can experience
with magnetic toys, magnet boards, or similar objects. A strange effect is
the unique ability of magnetic fields to penetrate many substances without any attenuation.
Though the physical basis of magnetism is well explored, the outsider
usually does not know very much about the details and sometimes tends to overestimate
the real possibilities provided by magnetism.
International competition and ever improving technology have forced manufacturers to increase quality as well as productivity. Often the improvement of quality is realized via the enhancement of production system precision. This chapter discusses some of the basic concepts in precision system design including
This chapter reviews various ways of damping large space trusses. The ﬁrst part discusses the use of active struts consisting of a piezoelectric actuator collocated with a force sensor. The guaranteed stability properties of the integral force feedback are reviewed and the practical signiﬁcance of the modal fraction of strain energy is stressed. The second part explains the concept of active tendon
