Freire, Juliana; Silva, Claudio T. | Towards enabling social analysis of scientific data | Flickr, Facebook, Yahoo! Pipes), which facilitate collaboration and sharing between users, are becoming increasingly popular. An important benefit of these sites is that they enable users to leverage the wisdom of the crowds. For example, in Flickr, users, in a mass collaboration approach, tag ... | Social data analysis; Scientific data; Workflows; Provenance; Pipelines; VisTrails | 2008 |

Shirley, Peter S.; Parker, Steven G. | Towards interactive global illumination effects via sequential Monte Carlo adaptation | This paper presents a novel method that effectively combines both control variates and importance sampling in a sequential Monte Carlo context while handling general single-bounce global illumination effects. The radiance estimates computed during the rendering process are cached in an adaptive per... | Ray tracing; Illumination; Monte Carlo methods | 2008 |

Gopalakrishnan, Ganesh | Towards providing low-overhead data race detection for large OpenMP applications | Neither static nor dynamic data race detection methods, by themselves, have proven to be sufficient for large HPC applications, as they often result in high runtime overheads and/or low race-checking accuracy. While combined static and dynamic approaches can fare better, creating such combinations, ... | | 2014-01-01 |

Balasubramonian, Rajeev | Towards scalable, energy-efficient, bus-based on-chip networks | It is expected that future on-chip networks for many-core processors will impose huge overheads in terms of energy, delay, complexity, verification effort, and area. There is a common belief that the bandwidth necessary for future applications can only be provided by employing packet-switched netwo... | On-chip networks; Multi-core computing; Bus-based; Energy efficient | 2010 |

Gopalakrishnan, Ganesh | Transaction ordering verification of the PCI 2.1 protocol using trace inclusion refinement | We define an abstract model of PCI, called PCIA, and show that PCI is a refinement of PCIA based on tract inclusion. We then show that no traces of PCIA violate the Producer/Consumer property using the mur? explicit state ennumeration model checker. Given that PCIA does not violate the Producer/Cons... | PCI; PCIA; tract inclusion | 2000 |

Hansen, Charles D. | Transfer function design based on user selected samples for intuitive multivariate volume exploration | Multivariate volumetric datasets are important to both science and medicine. We propose a transfer function (TF) design approach based on user selected samples in the spatial domain to make multivariate volumetric data visualization more accessible for domain users. Specifically, the user starts the... | | 2013-01-01 |

Organick, Elliott I. | Transformation of ADA programs into silicon (82 Mar. 1 - 82 Oct. 31) | This report outlines the beginning steps taken in an integrated research effort toward the development of a methodology, and supporting systems, for transforming Ada programs, or program units, (directly) into corresponding VLSI systems. The time seems right to expect good results. The need is evide... | Transformation; Silicon; Ada program units | 1982 |

Organick, Elliott I.; Lindstrom, Gary E. | Transforming an Ada program unit to silicon and verifying its behavior in an Ada environment: a first experiment | Microelectronics technology has advanced so rapidly and been so successful that we are new having to build large systems with a multitude of diverse, interacting components. Some components of these systems exhibit distinct architectures and may, in fact, be implemented following different choices o... | Transformation; Ada program units; Silicon | 1983 |

Starkey, Mike | Transforming disfigured and disoriented areas into routable switchboxes | Routing an entire circuit requires partitioning the circuit (routing area) into smaller, localized routing areas. Using non-rectangular, rotated switchbox shapes (and therefore non-manhattan routing layout) has the potential to simplify the partitioning of the circuit into routable areas and to use ... | Disfigured areas; Disoriented areas; routable switchboxes | 1991 |

Brunvand, Erik L. | Translating concurrent programs into delay-insensitive circuits | Programs written in a subset of occam are automatically translated into delay-insensitive circuits using syntax-directed techniques. The resulting circuits are improved using semantics-preserving circuit-to-circuit transformations. Since each step of the translation process can be proven correct, th... | | 1989 |

Organick, Elliott I.; Lindstrom, Gary E. | Transparent interface between software and hardware versions of ADA compilation units | The Ada-to-Silicon project at Utah is developing a methodology (and associated software and hardware) for the high level testing of Ada compilation units that are represented as hardware components (circuitry). There are two motivations for this research. | Ada-to-Silicon; ADA compilation units | 1983 |

Regehr, John | Two case studies in predictable application scheduling using Rialto/NT | This paper analyzes the results of two case studies in applying the Rialto/NT scheduler to real Windows 2000 applications. The first study is of a soft modem-a modem whose signal processing work is performed on the host CPU, rather than on a dedicated signal processing chip. The second is of an audi... | | 2001-01-01 |

Riloff, Ellen M. | Unified model of phrasal and sentential evidence for information extraction | Information Extraction (IE) systems that extract role fillers for events typically look at the local context surrounding a phrase when deciding whether to extract it.
