Gooch, Bruce; Shirley, Peter S. | Automatic image creation via artistic composition principles | Methods for choosing image parameters in both art and computer graphics are currently subjective. The choice of parameters results in images of varying quality. One aspect of image quality is the composition of the image. While the principles underlying composition are somewhat subjective, a portion... | Image parameters | 2000 |

Balasubramonian, Rajeev | Commit algorithms for scalable hardware transactional memory | In a hardware transactional memory system with lazy versioning and lazy conflict detection, the process of transaction commit can emerge as a bottleneck. For a large-scale distributed memory system, we propose novel algorithms to implement commit that are deadlock- and livelock-free and do not empl... | Commit algorithms; Scalable; Hardware; Transactional memory | 2007 |

Hibler, Michael J. | Separating presentation from interface in RPC and IDLs | In RPC-based communication, we term the interface the set of remote procedures and the types of their arguments; the presentation is the way these procedures and types are mapped to the target language environment in a particular client or server, including semantic requirements. For example, pres... | RPC-based communication; IDL; Presentation; Interface | 1995 |

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. OCCAM programs formed by such descriptions can be tested for correctness by executing the... | Lisp-based; Occam interpreter | 1991 |

Baxter, Brent S. | A standard magnetic tape format for digital image exchange | This proposal describes a simple yet flexible magnetic tape format for exchanging digital image information. Multi-dimensional arrays of raster scan data are stored as sequential files, with descriptive information related to the sefiles stored in an initial directory file. Directory information is ... | Raster scan data | 1981 |

Subrahmanyam, P.A. | An algebraic formulation of seitz's weak conditions for self timed circuits | Two fairly intuitive conditions are given that serve to algebraically characterize Seitz's "weak conditions" for self timed circuits. It is shown that these two conditions embody the 12 temporal logic conditions (developed b y Owicki and Malachi) which are intended to express both the weak condition... | Seitz's weak conditions; Self-timed circuits | 1982 |

Shirley, Peter S. | An anisotropic phong light reflection model | We present a new BRDF model that attempts to combine the advantages of the various empirical models currently in use. In particular, it has intuitive parameters, is anisotropic, energy-conserving, reciprocal, has an appropriate non-Lambertian diffuse term, and is well-suited for use in a Monte Carlo... | BRDF model; Anisotropic; Phong light reflection model | 2000 |

Cates, Joshua E.; Lefohn, Aaron; Whitaker, Ross T. | GIST: an interactive, GPU-based level set segmentation tool for 3D medical images | While level sets have demonstrated a great potential for 3D medical image segmentation, their usefulness has been limited by two problems. First, 3D level sets are relatively slow to compute. Second, their formulation usually entails several free parameters which can be very difficult to correctl... | GIST; 3D medical images; Segmentation tool; Image segmentation | 2004-02-27 |

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 |

Susarla, Sai R.; Carter, John | DataStations: ubiquitous transient storage for mobile users | In this paper, we describe DataStations, an architecture that provides ubiquitous transient storage to arbitrary mobile applications. Mobile users can utilize a nearby DataStation as a proxy cache for their remote home file servers, as a file server to meet transient storage needs, and as a platf... | DataStations; Ubiquitous transient storage; Proxy cache | 2003-11-14 |

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 |

Gopalakrishnan, Ganesh | An interface aware guided search method for error-trace justification in large protocols | Many 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 justification | 2008 |

Thompson, William B.; Willemsen, Peter; Gooch, Amy A.; Creem-Regehr, Sarah Hope | Does the quality of the computer graphics matter when judging distances in visually immersive environments? | In the real world, people are quite accurate judging distances to locations in the environment, at least for targets resting on the ground plane and distances out to about 20m. Distance judgments in visually immersive environments are much less accurate. Several studies have now shown that in vis... | Visually immersive environments | 2002-12-05 |

Awate, Suyash P.; Whitaker, Ross T. | Higher-order image statistics for unsupervised, information-theoretic, adaptive, image filtering | The restoration of images is an important and widely studied problem in computer vision and image processing. Various image filtering strategies have been effective, but invariably make strong assumptions about the properties of the signal and/or degradation. Therefore, these methods typically la... | Image filtering; Image restoration | 2005-04-15 |

Henderson, Thomas C. | Monte Carlo sensor networks | Biswas et al. [1] introduced a probabilistic approach to inference with limited information in sensor networks. They represented the sensor network as a Bayesian network and performed approximate inference using Markov Chain Monte Carlo (MCMC).

Henderson, Thomas C. | Parallel path consistency | Filtering algorithms are well accepted as a means of speeding up the solution of the consistent labeling problem (CLP). Despite the fact that path consistency does a better job of filtering than arc consistency, AC is still the preferred technique because it has a much lower time complexity. We ar... | Filtering algorithms; Parallel paths; Consistency; Consistent labeling problem; CLP | 1991 |

Cotter, Neil E. | Generality Vs. speed of convergence in the cart-pole balancer | This paper compares the speed of convergence to an optimal solution of four controllers for the problem of balancing a pole on a cart. We demonstrate that controllers whose design is tailored specifically to the cart-pole problem (i.e. less general) converge more rapidly to an optimal solution.
