    Independent verification and validation (IV&V) is defined as the confirmation by a group, agency, or company other than the original developer that a computer program was developed in accordance with the stated specification and satisfactorily performs the function(s) for which it was designed. The characteristics of IV&V are discussed, and the role played by the IV&V team during the various phase... View full abstract»

    Floating-point numbers are explained, and rounding, chopping, overflow, and underflow are discussed. The resulting errors are examined. An example is given to show the implications of roundoff in a very common type of calculation. Machine constants, error propagation and analysis, and some new ideas for computer arithmetic are considered.<> View full abstract»

    The mechanism that causes seismic activity and the two types of wave generated are described. The nature of long-, medium-, and short-term prediction is examined. The forecasting of earthquakes by animals, who forecast earthquakes at intervals ranging from three months down to about one minute, is examined, and the physiological factors that could account for it are discussed.<> View full abstract»

    An explanation is given of the four basic mechanisms for safeguarding intellectual property rights: copyrights, patent rights, trademarks, and trade secret laws. The extent to which they can be applied to computer hardware and software, and to what purpose and with what results, is explored.<> View full abstract»

    The author described a program, which provides a framework and a simple set of generic equations that may be used to simulate the in-flight characteristics of a conventional aircraft. Secondarily, the model will have realistic behavior when compared to existing aircraft. The implementation is explained by describing the major areas that constitute the model. These areas are: constants, aircraft pa... View full abstract»
