    • 2D-3D Rigid-Body Registration of X-Ray Fluoroscopy and CT Images 

      Zollei, Lilla (2001-08-01)
      The registration of pre-operative volumetric datasets to intra- operative two-dimensional images provides an improved way of verifying patient position and medical instrument loca- tion. In applications from orthopedics ...
    • An Accountable Source-To-Source Transformation System 

      Steele, Barbara Sue Kerne (1981-06-01)
      Though one is led to believe that program transformation systems which perform source-to-source transformations enable the user to understand and appreciate the resulting source program, this is not always the case. ...
    • Achieving Real-Time Mode Estimation through Offline Compilation 

      Van Eepoel, John M. (2002-10-22)
      As exploration of our solar system and outerspace move into the future, spacecraft are being developed to venture on increasingly challenging missions with bold objectives. The spacecraft tasked with completing these ...
    • ACTORS: A Model of Concurrent Computation in Distributed Systems 

      Agha, Gul Abdulnabi (1985-06-01)
      A foundational model of concurrency is developed in this thesis. We examine issues in the design of parallel systems and show why the actor model is suitable for exploiting large-scale parallelism. Concurrency in actors ...
    • ADAM: A Decentralized Parallel Computer Architecture Featuring Fast Thread and Data Migration and a Uniform Hardware Abstraction 

      Huang, Andrew "bunnie" (2002-06-01)
      The furious pace of Moore's Law is driving computer architecture into a realm where the the speed of light is the dominant factor in system latencies. The number of clock cycles to span a chip are increasing, while the ...
    • ADEPT: A Heuristic Program for Proving Theorems of Group Theory 

      Norton, Lewis Mark (1966-09-01)
      A computer program, named ADEPT (A Distinctly Empirical Prover of Theorems), has been written which proves theorems taken from the abstract theory of groups. Its operation is basically heuristic, incorporating many ...
    • AFL-1: A Programming Language for Massively Concurrent Computers 

      Blelloch, Guy (1986-11-01)
      Computational models are arising is which programs are constructed by specifying large networks of very simple computational devices. Although such models can potentially make use of a massive amount of concurrency, ...
    • An Algorithm for Parsing Flow Graphs 

      Brotsky, Daniel Carl (1984-03-01)
      This report describes research about flow graphs - labeled, directed, acyclic graphs which abstract representations used in a variety of Artificial Intelligence applications. Flow graphs may be derived from flow ...
    • Alignment by Maximization of Mutual Information 

      Viola, Paul A. (1995-03-01)
      A new information-theoretic approach is presented for finding the pose of an object in an image. The technique does not require information about the surface properties of the object, besides its shape, and is robust ...
    • AMAR: A Computational Model of Autosegmental Phonology 

      Albro, Daniel M. (1993-10-01)
      This report describes a computational system with which phonologists may describe a natural language in terms of autosegmental phonology, currently the most advanced theory pertaining to the sound systems of human ...
    • An Analog VLSI Chip for Estimating the Focus of Expansion 

      McQuirk, Ignacio Sean (1996-08-21)
      For applications involving the control of moving vehicles, the recovery of relative motion between a camera and its environment is of high utility. This thesis describes the design and testing of a real-time analog ...
    • Analysis and Control of Robot Manipulators with Kinematic Redundancy 

      Chang, Pyung H. (1987-05-01)
      A closed-form solution formula for the kinematic control of manipulators with redundancy is derived, using the Lagrangian multiplier method. Differential relationship equivalent to the Resolved Motion Method has been ...
    • Analysis and Implementation of Robust Grasping Behaviors 

      Chammas, Camille Z. (1990-05-01)
      This thesis addresses the problem of developing automatic grasping capabilities for robotic hands. Using a 2-jointed and a 4-jointed nmodel of the hand, we establish the geometric conditions necessary for achieving ...
    • An Analysis of the Effect of Gaussian Error in Object Recognition 

      Sarachik, Karen Beth (1994-02-01)
      Object recognition is complicated by clutter, occlusion, and sensor error. Since pose hypotheses are based on image feature locations, these effects can lead to false negatives and positives. In a typical recognition ...
    • The Architect's Collaborator: Toward Intelligent Tools for Conceptual Design 

      Koile, Kimberle (2001-01-01)
      In early stages of architectural design, as in other design domains, the language used is often very abstract. In architectural design, for example, architects and their clients use experiential terms such as "private" ...
    • ARLO: Another Representation Language Offer 

      Haase, Kenneth W., Jr. (1986-10-01)
      This paper describes ARLO, a representation language loosely modelled after Greiner and Lenant's RLL-1. ARLO is a structure-based representation language for describing structure-based representation languages, including ...
    • Assimilation of New Information by a Natural Language Understanding System 

      McDermott, Drew V. (1974-02-01)
      This work describes a program, called TOPLE, which uses a procedural model of the world to understand simple declarative sentences. It accepts sentences in a modified predicate calculus symbolism, and uses plausible ...
