    • Sparsely Faceted Arrays: A Mechanism Supporting Parallel Allocation, Communication, and Garbage Collection 

      Brown, Jeremy Hanford (2002-06-01)
      Conventional parallel computer architectures do not provide support for non-uniformly distributed objects. In this thesis, I introduce sparsely faceted arrays (SFAs), a new low-level mechanism for naming regions of memory, ...
    • Specialization of Perceptual Processes 

      Horswill, Ian (1995-04-22)
      In this report, I discuss the use of vision to support concrete, everyday activity. I will argue that a variety of interesting tasks can be solved using simple and inexpensive vision systems. I will provide a number ...
    • A Statistical Image-Based Shape Model for Visual Hull Reconstruction and 3D Structure Inference 

      Grauman, Kristen (2003-05-22)
      We present a statistical image-based shape + structure model for Bayesian visual hull reconstruction and 3D structure inference. The 3D shape of a class of objects is represented by sets of contours from silhouette ...
    • Statistical Object Recognition 

      Wells, William M. III (1993-01-01)
      Two formulations of model-based object recognition are described. MAP Model Matching evaluates joint hypotheses of match and pose, while Posterior Marginal Pose Estimation evaluates the pose only. Local search in pose ...
    • Stereo-Based Head Pose Tracking Using Iterative Closest Point and Normal Flow Constraint 

      Morency, Louis-Philippe (2003-05-01)
      In this text, we present two stereo-based head tracking techniques along with a fast 3D model acquisition system. The first tracking technique is a robust implementation of stereo-based head tracking designed for ...
    • Structural Dynamics Model of a Cartesian Robot 

      Reynoso, Alfonso Garcia (1985-10-01)
      Methods are developed for predicting vibration response characteristics of systems which change configuration during operation. A cartesian robot, an example of such a position-dependent system, served as a test case ...
    • Structure and Interpretation of Computer Programs 

      Abelson, Harold; Sussman, Gerald Jay (1983-07-01)
      "The Structure and Interpretation of Computer Programs" is the entry-level subject in Computer Science at the Massachusetts Institute of Technology. It is required of all students at MIT who major in Electrical ...
    • The Structure of Mathematical Knowledge 

      Michener, Edwina Rissland (1978-08-01)
      This report develops a conceptual framework in which to talk about mathematical knowledge. There are several broad categories of mathematical knowledge: results which contain the traditional logical aspects of ...
    • A Study of Qualitative and Geometric Knowledge in Reasoning about Motion 

      Forbus, Kenneth D. (1981-02-01)
      Reasoning about motion is an important part of our commonsense knowledge, involving fluent spatial reasoning. This work studies the qualitative and geometric knowledge required to reason in a world that consists of ...
    • Summarizing Qualitative Behavior from Measurements of NonlinearsCircuits 

      Lee, Michelle Kwok (1989-05-01)
      This report describes a program which automatically characterizes the behavior of any driven, nonlinear, electrical circuit. To do this, the program autonomously selects interesting input parameters, drives the circuit, ...
    • Surface Perception from Local Analysis of Texture and Contour 

      Stevens, Kent A. (1980-02-01)
      The visual analysis of surface shape from texture and surface contour is treated within a computational framework. The aim of this study is to determine valid constraints that are sufficient to allow surface orientation ...
    • Surface Reflectance Recognition and Real-World Illumination Statistics 

      Dror, Ron O. (2002-10-01)
      Humans distinguish materials such as metal, plastic, and paper effortlessly at a glance. Traditional computer vision systems cannot solve this problem at all. Recognizing surface reflectance properties from a single ...
    • Switching Between Discrete and Continuous Process Models to Predict Molecular Genetic Activity 

      Weld, Daniel Sabey (1984-05-01)
      Two kinds of process models have been used in programs that reason about change: Discrete and continuous models. We describe the design and implementation of a qualitative simulator, PEPTIDE, which uses both kinds of ...
    • Symbolic Integration 

      Moses, Joel (1967-09-01)
      SIN and SOLDIER are heuristic programs in LISP which solve symbolic integration problems. SIN (Symbolic INtegrator) solves indefinite integration problems at the difficulty approaching those in the larger integral ...
    • Symbolic Mathematical Laboratory 

      Martin, William A. (1967-01-01)
      A large computer program has been developed to aid applied mathematicians in the solution of problems in non-numerical analysis which involve tedious manipulations of mathematical expressions. The mathematician uses ...
    • Syntax-Based Analytic Reading of Musical Scores 

      Forte, Allen (1967-04-01)
      As part of a larger research project in musical structure, a program has been written which "reads" scores encoded in an input language isomorphic to music notation. The program is believed to be the first of its kind. ...
    • The Synthesis of Stable Force-Closure Grasps 

      Nguyen; Van-Duc (1986-07-01)
      This thesis addresses the problem of synthesizing grasps that are force-closure and stable. The synthesis of force-closure grasps constructs independent regions of contact for the fingertips, such that the motion of ...
    • Synthesizing Regularity Exposing Attributes in Large Protein Databases
