    • A Computational Model for Observation in Quantum Mechanics 

      Rozas, Guillermo Juan (1987-03-01)
      A computational model of observation in quantum mechanics is presented. The model provides a clean and simple computational paradigm which can be used to illustrate and possibly explain some of the unintuitive and ...
    • A Computational Model of Skill Acquisition 

      Sussman, Gerald J. (1973-08-01)
      This thesis confronts the nature of the process of learning an intellectual skill, the ability to solve problems efficiently in a particular domain of discourse. The investigation is synthetic; a computational performance ...
    • Computational Structure of GPSG Models: Revised Generalized Phrase Structure Grammar 

      Ristad, Eric Sven (1989-09-01)
      The primary goal of this report is to demonstrate how considerations from computational complexity theory can inform grammatical theorizing. To this end, generalized phrase structure grammar (GPSG) linguistic theory ...
    • Computational Structure of Human Language 

      Ristad, Eric Sven (1990-10-01)
      The central thesis of this report is that human language is NP-complete. That is, the process of comprehending and producing utterances is bounded above by the class NP, and below by NP-hardness. This constructive ...
    • Computer Analysis of Visual Properties of Curved Objects 

      Krakauer, Lawrence J. (1971-05-01)
      A method is presented for the visual analysis of objects by computer. It is particularly well suited for opaque objects with smoothly curved surfaces. The method extracts information about the object's surface properties, ...
    • Computer Recognition of Prismatic Solids 

      Griffith, Arnold K. (1970-08-01)
      An investigation is made into the problem of constructing a model of the appearance to an optical input device of scenes consisting of plane-faced geometric solids. The goal is to study algorithms which find the real ...
    • Computer Recognition of Three-Dimensional Objects in a Visual Scene 

      Guzman-Arenas, Adolfo (1968-12-01)
      Methods are presented (1) to partition or decompose a visual scene into the bodies forming it; (2) to position these bodies in three-dimensional space, by combining two scenes that make a stereoscopic pair; (3) to ...
    • Computer System for Visual Recognition Using Active Knowledge 

      Freuder, Eugene C. (1976-06-01)
      A system for visual recognition is described, with implications for the general problem of representation of knowledge to assist control. The immediate objective is a computer system that will recognize objects in a ...
    • Computing 3-D Motion in Custom Analog and Digital VLSI 

      Dron, Lisa (1994-11-28)
      This thesis examines a complete design framework for a real-time, autonomous system with specialized VLSI hardware for computing 3-D camera motion. In the proposed architecture, the first step is to determine point ...
    • Concurrent Aggregates (CA): An Object-Oriented Language for Fine-Grained Message-Passing Machines 

      Chien, Andrew Andai (1990-07-01)
      Fine-grained parallel machines have the potential for very high speed computation. To program massively-concurrent MIMD machines, programmers need tools for managing complexity. These tools should not restrict program ...
    • A Concurrent Smalltalk Compiler for the Message-Driven Processor 

      Horwat, Waldemar (1988-05-01)
      This thesis describes Optimist, an optimizing compiler for the Concurrent Smalltalk language developed by the Concurrent VLSI Architecture Group. Optimist compiles Concurrent Smalltalk to the assembly language of the ...
    • Concurrent Smalltalk on the Message-Driven Processor 

      Horwat, Waldemar (1991-09-01)
      Concurrent Smalltalk is the primary language used for programming the J- Machine, a MIMD message-passing computer containing thousands of 36-bit processors connected by a very low latency network. This thesis describes ...
    • Contact Sensing: A Sequential Decision Approach to Sensing Manipulation Contact 

      Eberman, Brian Scott (1995-05-01)
      This paper describes a new statistical, model-based approach to building a contact state observer. The observer uses measurements of the contact force and position, and prior information about the task encoded in a ...
    • Contact Sensors for Dexterous Robotic Hands 

      Siegel, David Mark (1986-06-01)
      This thesis examines a tactile sensor and a thermal sensor for use with the Utah-MIT dexterous four fingered hand. Sensory feedback is critical or full utilization of its advanced manipulatory capabilities. The hand ...
    • The Control of Human Arm Movement Models and Mechanical Constraints 

      Bennett, David J. (1990-05-01)
      A serial-link manipulator may form a mobile closed kinematic chain when interacting with the environment, if it is redundant with respect to the task degrees of freedom (DOFs) at the endpoint. If the mobile closed chain ...
    • Control of Vibration in Mechanical Systems Using Shaped Reference Inputs 

      Meckl, Peter Heinrich (1988-01-01)
      Dynamic systems which undergo rapid motion can excite natural frequencies that lead to residual vibration at the end of motion. This work presents a method to shape force profiles that reduce excitation energy at the ...
    • The Coupled Depth/Slope Approach to Surface Reconstruction 

      Harris, John G. (1986-06-01)
