  • Algorithms play the central role both in the science and practice of computing. Recognition of this fact has led to the appearance of a considerable number of textbooks on the subject. By and large, they follow one of two alternatives in presenting algorithms. One classifies algorithms according to a problem type. Such a book would have separate chapters on algorithms for sorting, searching, graphs, and so on. The advantage of this approach is that it allows an immediate comparison of, say, the efficiency of different algorithms for the same problem.

  • Nucleic Acid Hybridization Nucleic acid hybridization is a fundamental principle in molecular biology that takes advantage of the fact that the two complementary strands of nucleic acids bind, or hybridize, to one another with very high specificity. The goal of hybridization is to detect specific nucleic acid (DNA or RNA) sequences in a complex background of other sequences. This technique is used for Southern blotting, Northern blotting, and for screening libraries (see above). Further adaptation of hybridization techniques has led to the development of microarray DNA chips.

  • Continuing improvements led to the furnace and bellows and provided the ability to smelt and forge native metals (naturally occurring in relatively pure form).[38] Gold, copper, silver, and lead, were such early metals. The advantages of copper tools over stone, bone, and wooden tools were quickly apparent to early humans, and native copper was probably used from near the beginning of Neolithic times (about 8000 BC).[39] Native copper does not naturally occur in large amounts, but copper ores are quite common and some of them produce metal easily when burned in wood or charcoal fires.

  • The growth experience of India and other South Asian countries suggests that a “Service Revolution”—rapid income growth, job creation, gender equality, and poverty reduction led by services—is now possible. What is a service revolution? Can services be as dynamic as manufacturing? Can latecomers to development take advantage of the globalization of services? Can services be a driver of sustained growth, job creation, and poverty reduction? What kind of policies and institutions do developing countries need to benefit from services-led growth?...

  • Jensen (1990) and others used empirical evidence to demonstrate that there was a link between large pay bonuses provided to executives on a performance basis and improved corporate performance . Th ese theories in part motivated the trend be- ginning in the 1990s of deliberate struc- turing of corporate executive salaries to match performance of the corporation as closely as possible, usually through options to purchase shares in the com- pany on advantageous terms oﬀ ered to the executive.

  • This module provides students with a high level overview of the component architecture of Microsoft® Exchange 2000. They will learn that Exchange 2000 is designed to take advantage of Microsoft Windows® 2000. This has led to a number of fundamental architectural changes, including a more versatile information store service, placement of protocol management in the Internet Information Services, and event support for customizing mail-enabled software.

  • Applications that use HTML-based front ends benefit from the pervasive distribution of Web browsers for universal, cross-platform access. Another striking advantage of Web delivery lies in the concept of thin clients and centralized maintenance, facilitating instantaneous deployment of software updates at minimal cost. While the popularity of the Web and its advantages as a client-server platform have led to countless HTML-based applications, the development of Web applications is still mostly ad hoc.

  • The rapid growth of the portable electronics market includes ‘power-hungry’ accessories in a smaller system, which has led to the search for an alternative and advanced power source due to the limited energy density of conventional lithium-ion batteries. Table 1 lists the power demand of the different portable applications. Fuel cells promise to provide a more reliable and longer operational time than batteries. As the energy is stored as a reservoir rather than as an integral part of the power source, fuel cells have advantages over batteries.

  • Universal sensitivity to our environment and environmental considerations have led to the development of projects that not only minimize GHG (Green House Gas) emissions, but also help to displace GHG emissions from existing plants as well as other emissions sources. Thus, one of the more significant advantages for gas turbine, combined cycles and gas reciprocating engines is the potential for GHG reductions as compared to less efficient systems.
