    Logos, Biblios & Bibliotheke: Christian Influences In Library Development

    Full text link
    The influence of the Christian faith in the growth and development of libraries begins with the fundamental character of Yahweh, God of the Bible. By outlining the characteristics of Yahweh, we begin to understand the conceptual framework on which libraries have come to exist as intellectual, physical, spiritual, and social institutions. Given the limitations of space and format, I am confining my remarks to thematic possibilities, ideas that may merit further exploration. Essential to Yahweh\u27s character is that he acts in a powerful manner by speaking things into existence. He acts in a loving manner by creating individual human beings in his own image in order to have fellowship with them. Yahweh\u27s actions of power and love are essential to his nature. The steadfast love of the Lord never ceases, his mercies never come to an end; they are new every morning; great is your faithfulness

    Computability of Operators on Continuous and Discrete Time Streams

    Get PDF
    A stream is a sequence of data indexed by time. The behaviour of natural and artificial systems can be modelled bystreams and stream transformations. There are two distinct types of data stream: streams based on continuous time and streamsbased on discrete time. Having investigated case studies of both kinds separately, we have begun to combine their study in aunified theory of stream transformers, specified by equations. Using only the standard mathematical techniques of topology, wehave proved continuity properties of stream transformers. Here, in this sequel, we analyse their computability. We use the theoryof computable functions on algebras to design two distinct methods for defining computability on continuous and discrete timestreams of data from a complete metric space. One is based on low-level concrete representations, specifically enumerations, andthe other is based on high-level programming, specifically ‘while’ programs, over abstract data types. We analyse when thesemethods are equivalent. We demonstrate the use of the methods by showing the computability of an analog computing system.We discuss the idea that continuity and computability are important for models of physical systems to be “well-posed”
