    Electronic music synthesis is a process whereby several parts or elements of a musical composition that are performed or produced as separate entities are combined to form the entire or rendered composition. Since the entire process can seldom be carried out in real time, the synthesis of music has not been a performing-type rendition; therefore, the final product takes the form of a record that c...

    This article is devoted to the management problem of providing an environment favorable to the development of a reliable information and processing base for predictive technology. Much of the article is focused on assessment of risk in large projects that involve an organization of substantial size with several organizational levels and perhaps several departments. The discussion applies to all st... View full abstract»

    Electromagnetic wave propagation is a simple and beautiful phenomenon, but its rigorous mathematical derivation from Maxwell's equations is formidable. This article makes many of the concepts visible and plausible using only mathematics available to college freshmen and taught today in most high schools. Those who are familiar with the subject will appreciate the simple and direct way in which Dr.... View full abstract»

    In order to be effective, measurements must be unambiguous and quantitative, which is only possible when such measurements yield numerical values that can attach to a given aspect of the system being measured in only one way and have only one interpretation. This article discusses the use of correlation, transfer, and coherence functions in obtaining such measurements. View full abstract»
