Excerpt from Cyclopedia of Engineering, Vol. 6 of 7: A General Reference Work on Steam Boilers, Pumps, Engines, and Turbines The gases composing air are in the latter class; and air itself, therefore, for all practical purposes, may be looked upon as a perfect gas. In fact, the behavior of air is found in practice to conform so closely with the laws of perfect gases that the discrepancies may be ignored in ordinary calculations such as those involved in the present treatment of the subject. Table I, 'from Richards' Compressed Air, lists the weight of air per cubic foot at various temperatures Fahrenheit; also the volume of one pound of air at the same temperatures. The weight of a cubic foot of dry air at any atmospheric pressure and at any temperature Fahrenheit, may be found by dividing the constant 39 819 by the absolute temperature (temperature Fahrenheit The volume of one pound of dry air at atmospheric pres sure and any temperature, is found by dividing the absolute tempera ture by the constant Thus.

Excerpt from Cyclopedia of Engineering, Vol. 2 of 7: A General Reference Work on Steam Boilers, Pumps, Engines, and Turbines, Gas and Oil Engines, Automobiles, Etc Sir Humphry Davy showed that two pieces of ice might be melted by rubbing them together. He thus proved that heat can be produced by the expenditure of work only. This leads to the important conclusion that heat must be a form of energy, Since it can be produced from energy, and (as we know in the case of the steam engine) can itself be converted into well-recognized forms of energy.

Software engineering requires specialized knowledge of a broad spectrum of topics, including the construction of software and the platforms, applications, and environments in which the software operates as well as an understanding of the people who build and use the software. Offering an authoritative perspective, the two volumes of the Encyclopedia of Software Engineering cover the entire multidisciplinary scope of this important field. More than 200 expert contributors and reviewers from industry and academia across 21 countries provide easy-to-read entries that cover software requirements, design, construction, testing, maintenance, configuration management, quality control, and software engineering management tools and methods. Editor Phillip A. Laplante uses the most universally recognized definition of the areas of relevance to software engineering, the Software Engineering Body of Knowledge (SWEBOK®), as a template for organizing the material. Also available in an electronic format, this encyclopedia supplies software engineering students, IT professionals, researchers, managers, and scholars with unrivaled coverage of the topics that encompass this ever-changing field. Also Available Online This Taylor & Francis encyclopedia is also available through online subscription, offering a variety of extra benefits for researchers, students, and librarians, including: Citation tracking and alerts Active reference linking Saved searches and marked lists HTML and PDF format options Contact Taylor and Francis for more information or to inquire about subscription options and print/online combination packages.
