    This paper discusses the capabilities of APL2 for the implementation of frame systems and semantic networks, and for the use of object-oriented programming techniques. The fact that the frame is a basic data structure of APL2 makes this language very appropriate for the development of artificial intelligence applications using the indicated techniques. Examples are given of the way in which they m... View full abstract»

    Local area networks have been developed using both ring and bus topologies. Multi-loop and multi-connected topologies have been proposed to improve the throughput and dependability of single-loop networks. We evaluate the dependability of a class of multi-connected loop topologies called forward loop, backward hop (FLBH) networks and compare them to simple ring networks. View full abstract»

    The architecture, design, and implementation of a high-performance cache require a detailed consideration of the overall system functions closely coupled with the proper mapping and integration of these functions into the circuits and arrays. This approach has resulted in a new cache chip which incorporates a number of unique on-chip functions as well as unique design, providing a one-cycle cache ... View full abstract»

    The domain structure and its development in thin plane-parallel soft-magnetic elements have been investigated from both the experimental and the theoretical point of view. The experimental observations for verifying the predictions have been realized by means of the Bitter, Kerr, and Lorentz techniques. View full abstract»
