  • Molecular Docking Essay

    1925 Words  | 4 Pages

    Molecular docking is a key tool in structural molecular biology and computer-assisted drug design. The goal of ligand—protein docking is to predict the predominant binding mode(s) of a ligand with a protein of known three-dimensional structure. Successful docking methods search high-dimensional spaces effectively and use a scoring function that correctly ranks candidate dockings. Garrett M.

    'f'. As 'computer' names a nonnatural kind, almost everyone agrees that a computational interpretation of this sort is necessary for something to be a computer. But because everything in the universe satisfies at least one (mathematical) function, it is the sufficiency of such interpretations that is the problem. If, as anticomputationalists are fond of pointing out, computationalists are wedded to the view that a computational interpretation is sufficient for something to be a computer, then everything

    that allowed the user to calculate answers without doing arithmetic (Hoyle). In addition to the abacus and the Pascaline, Babbage's Folly, also known as the difference machine, "hastened the development of computers. [and] advanced the state of computational hardware" (Long 55). This engine, designed by the Cambridge professor Charles Babbage, could do any of the basic functions of mathematics: adding, subtracting, multiplying, and division in series at a "rate of 60 additions per minute" (55) could

    allows people with a disabilities to complete tests with minimal assistance. This allows the test results to be more valid since there is less enteraction between takers and givers. Test scoring can also be simplified and enhanced due to reduced computational errors. Test interpretation may be enhanced by providing the counselor with an expanded and consistent knowledge base to assist in the interpretation of test data. Computer-based test interpretation (CBTI) is typically based on research data and

    Model of Poetic Meter Abstract. Traditional analyses of meter are hampered by their inability to image the interaction of various elements which affect the stress patterns of a line of poetry or provide a system of notation fully amenable to computational analysis. To solve these problems, the connectionist models of James McClelland and David Rumelhart in Explorations in Parallel Distributed Processing (1988) are applied to the analysis of English poetic meter. The model graphically illustrates

  • From Mind to Supermind: A Statement of Aurobindonian Approach

    3378 Words  | 7 Pages

    outcome of all such discussions is that "mind" is mysterious and beyond all scientific explanation. According to the main contemporary view, in particular, `there is something essential in human understanding that is not possible to simulate by any computational means’. This indicates that the nature of mind continues to remain a source of acute discomfort to the Western thinkers. Even their new empirical findings regarding the highly complex mental acitivity is dubious. The object of this paper is to
