  • 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, and salinity.

  • 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.

  • 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.
