Sobh, Tarek M.; Henderson, Thomas C. | A dynamic framwork for intelligent inspection | CAD Computer Aided Design typically involves the design manufacture and inspection of a me chanical part. The problem of reverse engineering is to take an existing mechanical part as the point of departure and to inspect or produce a design and perhaps a manufacturing process for the part. ... | CAD; Manufacture; Inspection; Intelligent inspection | 1992 |

Sobh, Tarek M.; Henderson, Thomas C. | A dynamic recursive structure for intelligent exploration | We suggest a new approach for inspection and reverse engineering applications. In particular, we investigate the use of discrete event dynamic systems (DEDS) to guide and control the active exploration and sensing of mechanical parts for industrial inspection and reverse engineering.

Whitaker, Ross T. | A fast iterative method for a class of Hamilton-Jacobi equations on parallel systems | In this paper we propose a novel computational technique, which we call the Fast Iterative Method (FIM), to solve a class of Hamilton- Jacobi (H-J) equations on massively parallel systems. The proposed method manages the list of active nodes and iteratively updates the solutions on those nodes u... | Fast Iterative Method; FIM; Parallel systems | 2007 |

Smith, Kent F. | A fast parallel squarer based on divide-and-conquer | Fast and small squarers are needed in many applications such as image compression. A new family of high performance parallel squarers based on the divide-and-conquer method is reported.

Henderson, Thomas C.; Hansen, Charles D. | A fault tolerant sensor scheme | Multi-sensor systems pose the problem of how to coherently and efficiently treat the data provided by the various sensors. However. the availability of greater numbers of sensors also broadens the ability to build fault tolerant sensor systems. We define a framework in which sensors can be abstractl... | Multi-sensor systems; Logical sensors | 1983 |

Lindstrom, Gary E. | A framework for module-based language processors | A system composed of interconnected modules is a module-based system. We present an object-oriented (0-0) framework for the development of processors for module-based systems, such as compilers for 0-0 languages, linkers/loaders, and tools for user/system libraries. We claim t h a t this framework,... | Language processors; Jigsaw; Module-based | 1993 |

Michell, Nick | A gallium arsenide mutual exclusion element | A mutual exclusion element is a key component in building asynchronous and self-timed circuits. As part of our effort to design high performance self-timed circuits, we have designed a mutual exclusion element in gallium arsenide. This circuit has been fabricated in a 1.2? process and tested.

Mathew, Binu K.; Davis, Al; Fang, Zhen | A Gaussian probability accelerator for SPHINX 3 | Accurate real-time speech recognition is not currently possible in the mobile embedded space where the need for natural voice interfaces is clearly important. The continuous nature of speech recognition coupled with an inherently large working set creates significant cache interference with other... | Speech recognition; SPHINX 3; Speech recognizers | 2003-07-22 |

Gopalakrishnan, Ganesh | A general compositional approach to verifying hierarchical cache coherence protocols | Modern chip multiprocessor (CMP) cache coherence protocols are extremely complex and error prone to design. Modern symbolic methods are unable to provide much leverage for this class of examples. In [1], we presented a method to verify hierarchical and inclusive versions of these protocols using ... | Hierarchical cache coherence protocols; Verification | 2006-11-26 |

Yang, Yue; Gopalakrishnan, Ganesh; Lindstrom, Gary E. | A generic operational memory model specification framework for multithreaded program verification | Given the complicated nature of modern architectural and language level memory model designs, it is vital to have a systematic ap- proach for specifying memory consistency requirements that can support verification and promote understanding. In this paper, we develop a spec- ification methodolog... | Multithreaded program verification | 2003 |

Lefohn, Aaron; Whitaker, Ross T. | A GPU-based, three-dimensional level set solver with curvature flow | Level set methods are a powerful tool for implicitly representing deformable surfaces. Since their inception, these techniques have been used to solve prob- lems in fields as varied as computer vision, scientific visualization, computer graphics and computational physics.

Cohen, Elaine | A hole-filling algorithm for triangular meshes | Data obtained by scanning 3D models typically contains missing pieces and holes. These can be caused due to scanning artifacts or artifacts in the surface due to wear and tear.

Starkey, Mike | A lisp-based occam interpreter | The OCCAM programming language is an implementation of Communicating Sequential Processes and is used in a number of different areas. These areas usually require explicitly describing small-grain paralleslism.

Subrahmanyam, P.A. | A new approach to specifying and handling exceptions | An operation generally exhibits different patterns of behavior over different parts of its domain. Depending upon the context, such behavior may either be conceived of as "normal" or as an "exception." Thus, the behavior of an operation Is quite naturally characterized by the set of partial operatio... | Computer operations; Exceptions; Exception handling | 1980 |
