Gopalakrishnan, Ganesh | Performance studies of PV: an On-the-fly model-checker for LTL-X featuring selective caching and partial order reduction | We present an enumerative model-checker PV that uses a new partial order reduction algorithm called Twophase. This algorithm does not use the in-stack check to implement the proviso, making the combination of Twophase with on-the-fly LTL-X model-checking based on nested depth-first search, as well a... | Model-checker; PV; Performance; On-the-fly; Partial order reduction algorithm;' Twophase | 2001 |

Gooch, Bruce; Reinhard, Erik | Perception-driven black-and-white drawings and caricatures | In this paper, we present a method for automatically creating black-and-white drawings of human faces from photographs. We then demonstrate new techniques for deforming these drawings to create caricatures intended to highlight and exaggerate facial features.

Parker, Steven G.; Hansen, Charles D.; Johnson, Christopher R. | Computational steering and the SCIRun integrated problem solving environment | SCIRun is a problem solving environment that allows the interactive construction, debugging, and steering of large-scale scientific computations. We review related systems and introduce a taxonomy that explores different computational steering solutions.

Keller, Robert M. | Semantics of networks containing indeterminate operators | We discuss a denotational semantics for networks containing indeterminate operators. Our approach is based on modelling a networks by the set of all its possible behaviors. Our notion of behavior is a sequence of computational actions. The primitive computational action is an event: the appearance o... | 1984 | |

Kirby, Robert Michael II | On the use of adjoint-based sensitivity estimates to control local mesh refinement | The goal of efficient and robust error control, through local mesh adaptation in the computational solution of partial differential equations, is predicated on the ability to identify in an a posteriori way those localized regions whose refinement will lead to the most significant reductions in the ... | Sensitivity; Adaptivity; Error estimation; hp-finite elements; Discrete adjoint; Mesh refinement | 2009 |

Brown, Bruce Eric | Modeling of solids for three-dimensional finite element analysis | The geometric modeling of solid objects is a major problem within the design analysis loop of the engineering design process. Models are analyzed by various computer programs to predict their performance. The format of each model is usually different for each analysis routine. The existence of sev... | Geometric modeling; Solid objects; Finite element analysis | 1977 |

Keller, Robert M. | Semantics of parallel program graphs | A denotational model for networks of parallel processes is presented which generalizes the work of Kahn by using alternative data types, e.g. Lisp-like operators on trees. It is shown that the ordering aspect of data types plays a central role in determining how much parallelism can be present. It i... | Parallel program graphs; Computer semantics; Denotational model | 1977 |

Lindstrom, Gary E. | Modular language processors as framework completions | The conceptual and specificational power of denotational semantics for programming language design has been amply demonstrated. We report here on a language implementation method that is similarly semantically motivated, but is based upon object-oriented design principles, and results in flexible an... | Modular language processors; Denotational semantics; Framework completions | 1993 |

Henderson, Thomas C.; Sikorski, Christopher | Symmetry: a basis for sensorimotor reconstruction | Given a set of unknown sensors and actuators, sensorimotor reconstruction is achieved by exploiting relations between the sensor data and the actuator control data to determine sets of similar sensors, sets of similar actuators, necessary relations between them, as well as sensorimotor relations ... | sensorimotor reconstruction; sensor data; actuator control data | 2011 |

Brunvand, Erik L. | Self-timed circuits using DCVSL semi-bundled delay wrappers | We present a technique for generating robust self-timed completion signals for general dynamic datapath circuits. The wrapper circuit is based on our previous domino semi-bundled delay (SBD) circuits, but uses DCVSL circuits in the wrapper for higher performance. We describe the basic SBD-DCVSL... | 2005 | |

Lindstrom, Gary E. | Toward function-based distributed database systems | We discuss the suitability of a function-based (or "applicative") approach to the construction of distributed database systems. Certain aspects of applicative systems are immediatley appealing for this purpose (e.g. data oriented toward conceptual objects rather than toward particular representation... | Function-based; distributed database systems; applicative | 1982 |

Carter, John B. | Design of a parallel vector access unit for SDRAM memory systems | Parallel Vector Access is a technique that exploits the regularity of vector or stream accesses to perform them efficiently in parallel on a multi-bank memory system. The performance of applications that have vector accesses may be improved using a memory controller that performs scatter/gather oper... | Parallel vector access; SDRAM memory; Multi-bank memory system | 1999 |

Balasubramonian, Rajeev | Dynamically managing the communication-parallelism trade-off in future clustered processors | Clustered microarchitectures are an attractive alternative to large monolithic superscalar designs due to their potential for higher clock rates in the face of increasingly wire-delay-constrained process technologies.

Bruderlin, Beat | Moving into higher dimensions of geometric constraint solving | In this paper, we present an approach to geometric constraint solving, based on degree of freedom analysis. Any geometric primitive (point, line, circle, plane, etc.) possesses an intrinsic degree of freedom in its embedding space which is usually two or three dimensional.
