  • Seven years have passed since the publication of the previous edition of this book. During that time, sensor technologies have made a remarkable leap forward. The sensitivity of the sensors became higher, the dimensions became smaller, the selectivity became better, and the prices became lower. What have not changed are the fundamental principles of the sensor design. They are still governed by the laws of Nature. Arguably one of the greatest geniuses who ever lived, Leonardo Da Vinci, had his own peculiar way of praying.

  • We Americans assume that our economic system will always scamper to provide us with the products we want. Special orders don’t upset us! I want my MTV! The truth is more complicated, especially in our education system, which is paid for by the students but controlled by the professoriate. Witness the perverse success of the bloated science textbook.

  • Prior to 1970, texts concerned with comparative and international issues and dimensions were relatively rare. A few American commentators devoted some attention to developments in sport in the then Soviet Union and also produced, through assembled descriptive accounts, information on health, physical education and recreation in a number of countries around the world. After 1970, there was an increasing interest in international aspects of physical education, testimony to which was the plethora of descriptive articles contributed to professional journals by American physical educators.

  • Physics explains everything from the beginning to the end of any complete description of the human body. Such a comprehensive discussion should begin with the basic structure of matter, as explained by quantum mechanics – the physics at small dimensions, and end with the mechanics of human motion, the energetics of metabolism, the fluid dynamics of blood flow through vessels, the mechanisms for speaking and hearing, and the optical imaging system we call the eye.

The measurement is not only the definite size of physical dimension but also whatever concepts, which can be compared each other.

  • Microsensors are appropriately categorized as “transducers”, which are defined as devices that convert energy from one form to another. In the case of microsensors, the device typically converts a measured mechanical signal into an electrical signal. The critical physical dimensions of microsensors devices can vary from well below one micron on the lower end of the dimensional spectrum, all the way to several millimeters.

  • The papers in this book provide new information on several aspects of soil erosion and applications of the National Resources Inventory (NRI). They were commissioned following a planning workshop in July 1984 and were presented in December 1984 during a national convocation, “Physical Dimensions of the Erosion Problem.” The workshop and convocation were held by the National Research Council's Board on Agriculture in response to a request from the Soil Conservation Service of the U.S.

  • Great companies and organizations project a strong sense of themselves that everyone can recognize: Disney’s imagination, Nike’s drive, IBM’s methodical dependability, or Nordstrom’s service.These companies know who they are, and they behave that way consistently, day in and day out. Successful, enduring companies have at their core a personality that we connect with and understand. In fact, all companies have a personality—because companies are people, too.

  • We have attempted to improve and update this text while retaining the features that make it unique, namely, an emphasis on physical understanding, and the ability to estimate, evaluate, and predict results without blind reliance on computers, while still maintaining rigorous connection to the mathematical basis for quantum chemistry. We have inserted intomost chapters examples that allowimportant points to be emphasized, clarified, or extended. This has enabled us to keep intact most of the conceptual development familiar to past users.

  • On 21 March 1990 John Hammersley celebrates his seventieth birthday. A number of his colleagues and friends wish to pay tribute on this occasion to a mathematician whose exceptional inventiveness has greatly enriched mathematical science. The breadth and versatility of Hammersley’s interests are remarkable, doubly so in an age of increased specialisation. In a range of highly individual papers on a variety of topics, he has theorised, and posed (and solved) problems, thereby laying the foundations for many subjects currently under study.

  • The general picture is that older people of today are healthier than older people of two decades ago. There have been improvements in most dimensions of health. People live longer and have fewer disabilities, have less functioning loss, and report themselves to be in better health. Over time there has been some reduction in risk from smoking and a lowering of cholesterol and average triglyceride levels. However, weight increase has been notable during this period.

  • Two hundred years ago, Lewis and Clark led their “Corps of Discovery” on an unprecedented expedition to explore the vast dimensions of the nation’s longest and largest river basin—the Missouri. Their central charge was to seek a water route to the Pacific Ocean to support commerce and development. Since those early days, the Missouri River and its tributaries have occupied a unique place in United States history.

  • Structural analysis is the study of the nature of connection among the members of a mechanism and its mobility. It is concerned primarily with the fundamental relationships among the degrees of freedom, the number of links, the number of joints, and the type of joints used in a mechanism. It should be noted that structural analysis only deals with the general functional characteristics of a mechanism and not with the physical dimensions of the links. A thorough understanding of the structural characteristics is very helpful for enumeration of mechanisms. ...
