76 Greenfield, HarveyAn application of computer graphics: two concurrent investigations within the medical fieldThe aim of this project is to apply new or recently developed computer graphic techniques to a particular discipline with the thought of broadening its research capabilities. The discipline chosen, that of medicine, has emphasis places on the area of hemodynamics. It is seen that computer graphics m...Computer graphic techniques1971
77 Keller, Robert M.An approach to determinacy proofsIt is known that any parallel program graph composed of continuous operators itself represents a continuous function. In other words, the network is determinate in the sense that for a given input, the output is unique, independent of the timing of the constituent operators. This result is applied t...Parallel program graph; Determinacy proofs1978
78 Henderson, Thomas C.An approach to three-dimensional scene databasesCurrent image database research is concerned for the most part with the encoding and processing of two-dimensional images. However, the most successful approach to computer vision is based on 3-dimensional information, organized as either stacks of 2-D images (e.g., the intrinsic images of Barrow an...Image databases; Three-dimensional; Scene databases1987
79 Keller, Robert M.; Lindstrom, Gary E.An architecture for a loosely-coupled parallel processorAn architecture for a large (e. g. 1000 processor) parallel computer is presented. The processors are loosely-coupled, in the sense that communication among them is fully asynchronous, and each processor is generally not unduly delayed by any immediate need for specific data values. The network supp...Loosely-coupled; Parallel processors1978
80 Bruderlin, BeatAn axiomatic approach for solving geometric problems symbolicallyThis paper describes a new approach for solving geometric constraint problems and problems in geometry theorem proving. We developed a rewrite-rule mechanism operating on geometric predicates. Termination and completeness of the problem solving algorithm can be obtained through well foundedness and ...Geometric constraint problems; Geometry theorem proving; Knuth-Bendix completion algorithm1990
81 Willemsen, Peter; Gooch, Amy A.An experimental comparison of perceived egocentric distance in real, image-based, and traditional virtual environment using direct walking tasksIn virtual environments, perceived egocentric distances are often underestimated when compared to the same distance judgments in the real world. The research presented in this paper explores two possible causes for this reduced distance perception in virtual environments: (1) real-time computer g...Egocentric distances; Virtual environments2002-02-12
82 Newman, William M.An experimental display programming language for the PDP-10 computerAn experimental language for display programming, called DIAL, has been developed for the PDP-10 and the UNIVAC 1559 display. It is experimental in the sense that it was originally conceived as a means of testing out some ideas, and the best way to test them seemed to be to produce a language that ...Display programming; DIAL; Display Algol1970
83 Riesenfeld, Richard F.; Smith, Kent F.An experimental system for computer aided geometric designThe main goal of this proposed level-of-effort project is to extend present capabilities in the area of Computer Aided Geometric Design (CAGD) and to develop custom VLSI support for some special geometric functions.Computer aided geometric design; CAGD; VLSI; Very large scale integration1984
84 Khoche, AjayAn extended cell set of self-timed designsThe high level synthesis approach described in [1] uses hopCP[2] language for behavioral descriptions. The behavioral specifications are then translated into Hop Flow Graphs (HFGs). The actions in the graph are then refined such that refined actions can be directly mapped onto asynchronous circuit b...Self-timed designs; hopCP; Hop Flow Graphs; Asynchronous circuit blocks; Action-blocks1993
85 Gopalakrishnan, Ganesh; Humphrey, Alan Parker; Derrick, Christopher GladeAn integration of dynamic MPI formal verification within eclipse PTPOur research goals were to verify practical MPI programs for deadlocks, resource leaks, and assertion violations at the push of a button and be able to easily visualize the results. We also sought to integrate these capabilities with the Eclipse IDE via an Eclipse plug-in for the Parallel Tools Plat...Verification; Graphical User Interfaces; Dynamic Interleaving Reduction; Message Passing; MPI; Multi-core; Eclipse Parallel Tools Platform; Trapeze Interactive Poster2010-03-15
86 Bruderlin, BeatAn interactive N-Dimensional constraint systemIn this paper, we present a graph-based approach to geometric constraint solving. Geometric primitives (points, lines, circles, planes, etc.) possess intrinsic degrees of freedom in their embedding space. Constraints reduce the degrees of freedom of a set of objects. A constraint graph is created wi...Geometric constraint solving1994
87 Gopalakrishnan, GaneshAn interface aware guided search method for error-trace justification in large protocolsMany complex concurrent protocols that cannot be formally verified due to state explosion can often be formally verified by initially creating a collection of abstractions (overapproximations), and subsequently refining the overapproximated protocol in response to spurious counterexample traces. ...Concurrent protocols; Verification; Error-trace justification2008
88 Sikorski, KrisAn interior ellipsoid algorithm for fixed pointsWe consider the problem of approximating fixed points of non-smooth contractive functions with using of the absolute error criterion. In [12] we proved that the upper bound on the number of function evaluations to compute ?-approximations is 0(n3(In 1/? + In 1/1-q +In n)) in the worst case, where ...Ellipsoid algorithm; Contractive functions; Fixed points1998
89 Davis, AlAn introduction to asynchronous circuit designThe purpose of this monograph is to provide both an introduction to field of asynchronous digital circuit design and an overview of the practical state of the art in 1997. In the early days of digital circuit design, little distinction was made between synchronous and asynchronous circuits. However,...Asynchronous circuit design1997
90 Riloff, Ellen M.An introduction to the Sundance and AutoSlog systemsThis document describes the Sundance natural language processing system that has been developed at the University of Utah, as well as the AutoSlog and AutoSlog-TS extraction pattern learners that have been implemented on top of Sundance.

91 Regehr, JohnAn isotach implementation for myrinetAn isotach network provides strong guarantees about message delivery order. We show that an isotach network can be implemented efficiently entirely in software, using commercial o-the-shelf hardware. This report describes that effort. Parts of this implementation could be performed much more efficie...1997-01-01
