Mathews, V. John | Adaptive, quadratic preprocessing of document images for binarization | Abstract-This paper presents an adaptive algorithm for preprocessing document images prior to binarization in character recognition problems. Our method is similar in its approach to the blind adaptive equalization of binary communication channels. The adaptive filter utilizes a quadratic system mod... | | 1998 |

Simpson, Jamesina J. | ADE-FDTD scattered-field formulation for dispersive materials | This letter presents a scattered-field formulation for modeling dispersive media using the finite-difference time-domain (FDTD) method. Specifically, the auxiliary differential equation method is applied to Drude and Lorentz media for a scattered field FDTD model. The present technique can also be a... | | 2008-01-01 |

Stringfellow, Gerald B.; Shurtleff, James Kevin | Adsorption and desorption of the surfactant Sb on GaInP grown by organometallic vapor phase epitaxy | It has been determined that ordering has a profound effect on the bandgap energy of many compound semiconductor alloys. Therefore, ordering must be controlled for devices such as solar cells, light emitting diodes and diode lasers. Since ordering depends on the surface properties during organomet... | Time dependent surface photoabsorption (SPA); Compound semiconductor alloys | 2000 |

Henderson, Thomas C. | Agent-based engineering drawing analysis | Interpretation of paper drawings has received a good deal of attention over the last decade. Related areas such as direct interpretation of human drawings (HCI), search and indexing of graphics databases, and knowledge representation in the domain of graphics and drawing understanding have also s... | Interpretation; Human drawings; HCI; Graphic databases | 2002-02-04 |

Scarpulla, Michael | Air shear driven flow of thin perfluoropolyether polymer films | We have studied the wind driven movement of thin perfluoropolyether (PFPE) polymer films on silicon wafers and CNx overcoats using the blow-off technique. The ease with which a liquid polymer film moves across a surface when sheared is described by a shear mobility xS , which can be interpreted both... | Perfluoropolyether; Polymer films; Air shear; Shear mobility | 2003 |

Tasdizen, Tolga | Algebraic curves that work better | An algebraic curve is defined as the zero set of a polynomial in two variables. Algebraic curves are practical for modeling shapes much more complicated than conics or superquadrics. The main drawback in representing shapes by algebraic curves has been the lack of repeatability in fitting algebraic... | | 1999 |

Stevens, Kenneth | Algorithms for MIS vector generation and pruning | Ignoring the effect of simultaneous switching for logic gates causes silicon failures for high performance microprocessor designs. The main reason to omit this effect is the run time penalty and potential over-conservatism. Run times are directly proportional to the vector sizes. Efficient algorithm... | | 2006 |

Crow, Franklin C. | The aliasing problem in computer-synthesized shaded images | This paper describes work toward improving the quality of computer-synthesized shaded images. Current (practical) hidden-surface algorithms produce an image whose precision is strictly limited by the number of picture elements. Problems caused by this limitation are described and explained in the t... | aliasing problem; shaded images; hidden-surface algorithms | 1976 |

Lindstrom, Gary E. | Alpha-beta pruning on evolving game trees | The alpha-beta strategy is a widely used method for economizing on the size of game trees. Heretofore, its application has been limited to depth-first tree growth in recursive search functions. However, many modern game players use retentive (i.e. coroutine-based) control to achieve greater attentio... | Alpha-beta pruning; Game trees | 1979 |

Stevens, Kenneth | An A-FPGA architecture for relative timing based asynchronous designs | This paper presents an asynchronous FPGA architecture that is capable of implementing relative timing based asynchronous designs. The architecture uses the Xilinx 7-Series architecture as a starting point and proposes modifications that would make it asynchronous design capable while keeping it full... | | 2014-01-01 |

George, Lal | An abstract machine for parallel graph reduction | An abstract machine suitable for parallel graph reduction on a shared memory multiprocessor is described. Parallel programming is plagued with subtle race conditions resulting in deadlock or fatal system errors. Due to the nondeterministic nature of program execution the utilization of resources ma... | Parallel graph reduction; Abstract machines | 1989 |

George, Lal | An abstract machine for parallel graph reduction | An abstract machine for parallel graph reduction on a shared memory multiprocessor is described. This is intended primarily for normal order (lazy) evaluation of functional programs. It is absolutely essential in such a design to adapt an efficient sequential model since during execution under limit... | Parallel graph reduction | 1989 |

Mathews, V. John | An adaptive channel estimator for CDMA systems in multipath fading channels | ABSTRACT CDMA systems in multipath fading channels need to estimate channel parameters for coherent detection of the transmitted signals.

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 |

Mathews, V. John | An analytical model of the perceptual threshold function for multichannel image compression | ABSTRACT The human observer is often the final judge of the quality of compressed images. One way to design a compression system that attempts to reduce or eliminate subjective distortions in the coded images is to incorporate a perceptual threshold function model into the compression system.

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 |

Keller, Robert M. | An approach to determinacy proofs | It is known that any parallel program graph composed of continuous operators itself represents a continuous function. In other words, the network is determinate in the sense that for a given input, the output is unique, independent of the timing of the constituent operators. This result is applied t... | Parallel program graph; Determinacy proofs | 1978 |

Henderson, Thomas C. | An approach to three-dimensional scene databases | Current image database research is concerned for the most part with the encoding and processing of two-dimensional images. However, the most successful approach to computer vision is based on 3-dimensional information, organized as either stacks of 2-D images (e.g., the intrinsic images of Barrow an... | Image databases; Three-dimensional; Scene databases | 1987 |

Keller, Robert M.; Lindstrom, Gary E. | An architecture for a loosely-coupled parallel processor | An architecture for a large (e. g. 1000 processor) parallel computer is presented. The processors are loosely-coupled, in the sense that communication among them is fully asynchronous, and each processor is generally not unduly delayed by any immediate need for specific data values. The network supp... | Loosely-coupled; Parallel processors | 1978 |
