    This paper is based on a review of the literature about controlled experiments in research on knowledge acquisition. The review was carried out to help the author make decisions about the design of his own experiment comparing two knowledge-acquisition methods. The paper looks critically at six experiments reported in the literature, and proposes a framework within which such empirical work can be... View full abstract»

    The LLILOG knowledge representation language and an inference engine to interpret it have been developed as part of the LILOG project, where new concepts for understanding natural-language texts were investigated. LLILOG is a typed predicate logic whose type system has adopted the concepts of KL-One-like languages. Further language constructs allow the formulation of default ... View full abstract»

    GF11 is a 512-way SIMD parallel computer currently used to verify quantum chromodynamics theory and to explore the SIMD approach to parallel processing. System design choices, such as network design, processing element design, and other architectural features, allow GF11 to sustain very high performance, close to the 10-gigaFLOPS peak. Several applications, such as structural analysis, seismic mod... View full abstract»

    The architecture, design, and performance of multiprocessors in the Application System/400® (AS/400®) family are discussed. The paper describes how this multitasking system, originally designed as a uniprocessor system, was modified to form a multiprocessor system. The unique approach, using relatively atomic instructions, required a minimum of change while providing significant perf... View full abstract»
