Heating and cooling load calculations are then explained in a thorough yet understandable manner. The subject of psychrometrics is presented in considerable detail, since it is at the heart of under-standing air conditioning processes.

Construction, selection, design, and performance of air conditioning and refrigeration equipment and systems, and two example projects illustrating design of a heating and cooling system are described in depth. A special chapter is devoted to energy utilization and conservation in design, installation, and operation of air conditioning systems.

The book fully explores the basic theory and also covers emerging concepts and technologies. The conventional topics of transmission subsystem including HVDC transmission are also discussed, along with an introduction to new technologies in power transmission and control such as Flexible AC Transmission Systems (FACTS).

Numerous solved examples, inter-spersed throughout, illustrate the concepts discussed. What is New to This Edition : Provides two new chapters on Diesel Engine Power Plants and Power System Restructuring to make the students aware of the changes taking place in the power system industry.

Includes more solved and unsolved problems in each chapter to enhance the problem solving skills of the students. Primarily designed as a text for the undergraduate students of electrical engineering, the book should also be of great value to power system engineers.

Nanotechnology is like a toolkit for the electronics industry. It gives tools to make electronic nanomaterials with special properties modified by ultrafine particle size, crystallinity, structure or surfaces.

New nanoelectronics technologies are emerging that promise to carry us beyond the limits of present lithographic processing down to molecular feature sizes. Denser hard drives, smaller and faster chips, and (less)

Cohan draws on examples from such highly valued companies as Synopsys, WalMart, Goldman Sachs, MBNA, Johnson & Johnson, J.M.

Smucker, Southwest Airlines, and Microsoft to illustrate these principles. He also offers a tool, the "Value Quotient," to help executives assess their value leadership and suggests a process that executives can follow to close that gap.

However, intention is viewed very differently in this book. Dr.

Wayne W. Dyer has researched intention as a force in the universe that allows the act of creation to take place.

A strong vocabulary and the ability to appreciate the contextual usage of words provide a great mileage in cracking the VA section. A lot of students, especially those with English not as their first language, do not have an advanced level of word power.

Therefore, they find themselves at a disadvantage when it comes to cracking the VA section. These students generally adopt the following conventional methods to build their vocabulary: ? Cramming wordlists, fl ash cards etc: It is a stressful 'memory based' method to build one's vocabulary.

Here emphasis is more on 'remembering the meanings' of the words rather than on 'appreciating the context' in which they are used. ? Reading good novels, storybooks, newspaper editorials etc: It is an effective method of building.

The rise of private power may be the most important and least understood trend of our time. David Rothkopf provides a fresh, timely look at how we have reached a point where thousands of companies have greater power than all but a handful of states.

Beginning with the story of an inquisitive Swedish goat wandering off from his master and inadvertently triggering the birth of the oldest company still in existence, Power, Inc. follows the rise and fall of kings and empires, the making of great fortunes, and the chaos of bloody revolutions.

A fast-paced tale in which champions of liberty are revealed to be paid pamphleteers of moneyed interests and greedy scoundrels trigger changes that lift billions from deprivation, Power, Inc. traces the bruising jockeying for influence right up to today's financial crises, growing inequality, broken international (less)
