Freire, Juliana | Designing information-preserving mapping schemes for XML | An XML-to-relational mapping scheme consists of a procedure for shredding XML documents into relational databases, a procedure for publishing databases back as documents, and a set of constraints the databases must satisfy. In previous work, we discussed two notions of information preservation for m... | Losslessness; Validation; Mapping scheme; Edge++; LILO; Lossless Inlining; Lossless Outlining; XML Schema | 2005 |

Bruderlin, Beat | Detecting ambiguities: an optimistic approach to robustness problems in computational geometry | Computational geometry algorithms deal with geometric objects, usually represented by coordinates in an n-dimensional Euclidean space. Most efficient algorithms implement geometric operations as floating point arithmetic operations on the coordinates. Since floating point numbers can only approxima... | Ambiguities; Computational geometry; Robustness problems | 1990 |

Kasera, Sneha K. | Detecting receiver attacks in VRTI-based device free localization | Variance-based Radio Tomographic Imaging (VRTI) is an emerging technology that locates moving objects in areas surrounded by simple and inexpensive wireless sensor nodes. VRTI uses human motion induced variation in RSS and spatial correlation between link variations to locate and track people. An ar... | | 2012-01-01 |

Brunvand, Erik L. | DFT for fast testing of self-timed control circuits | In this paper, we present a methodology to perform fast testing of the control path of self-timed circuits [91]. The speedup is achieved by testing all the execution paths in the control simultaneously. The circuits considered in this paper are those designed using an OCCAM based circuit compile... | | 1995 |

Faugeras, Olivier Dominique | Digital color image processing and psychophysics within the framework of a human visual model | A three-dimensional homomorphic model of human color vision based on neurophysiological and psychophysical evidence is presented. This model permits the quantitative definition of perceptually important parameters such as brightness. saturation, huo and strength.

Colas-Baudelaire, Patrick | Digital picture processing and psychophysics: a study of brightness perception | A computer driven display system was used to study brightness contrast phenomena, in a project motivated by research in digital picture processing. The modeling approach was that of Stockham and Davidson: the visual system is modeled as the cascade of a linear system (eye optics) and a multiplicati... | Digital picture processing; Computer driven display system; Brightness contrast | 1974 |

Stoller, Leigh B. | Direct deposit: a basic user-level protocol for carpet clusters? | This note describes the Direct Deposit Protocol (DDP), a simple protocol for multicomputing on a carpet cluster. This protocol is an example of a user-level protocol to be layered on top of the low-level, sender-based protocols for the Protocol Processing Engine. The protocol will be described in te... | Direct Deposit Protocol; DDP; Carpet clusters; Multicomputing; User-level protocol | 1995 |

Regehr, John; Pagariya, Rohit Pannalalji | Direct equivalence testing | Testing embedded software is difficult. • Further complicated by presence of memory and type safety errors in software. • Compiler contain various known bugs. Developers are skeptical to upgrade the compilers. • Is your embedded software affected by memory safety and compilation erro... | | |

Shirley, Peter S. | Direct Ray tracing of smoothed and displacement mapped triangles | We present an algorithm for ray tracing displacement maps that requires no additional storage over the base model. Displacement maps are rarely used in ray tracing due to the cost associated with storing and intersecting the displaced geometry. This is unfortunate because displacement maps allow the... | Ray tracing displacement maps | 2000 |

Peterson, John W. | Distributed computation for computer animation | Computer animation is a very computationally intensive task. Recent developments in image synthesis, such as shadows, reflections and motion blur enhance the quality of computer animation, but also dramatically increase the amount of CPU time needed to do it. Fortunately, the computations involved w... | Distributed computation | 1987 |

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 |

Riloff, Ellen M. | Domain-specific coreference resolution with lexicalized features | Most coreference resolvers rely heavily on string matching, syntactic properties, and semantic attributes of words, but they lack the ability to make decisions based on individual words. In this paper, we explore the benefits of lexicalized features in the setting of domain-specific coreference reso... | | 2014-01-01 |

Lepreau, Jay | DRAFT: work in progress - - - comments solicited evolving Mach 3.0 to use migrating threads | Like most operating systems, Mach 3.0 views threads as statically associated with a single task. An alternative model is that of migrating threads, in which a single thread abstraction moves between tasks with the logical flow of control, and "server" code is passively executed. We have compatibly r... | DRAFT | 1993 |

Balasubramonian, Rajeev | Dynamic hardware-assisted software-controlled page placement to manage capacity allocation and sharing within large caches | In future multi-cores, large amounts of delay and power will be spent accessing data in large L2/L3 caches. It has been recently shown that OS-based page coloring allows a non-uniform cache architecture (NUCA) to provide low latencies and not be hindered by complex data search mechanisms.
