    • Dynamic Interactions Between Limb Segments During Planar Arm Movement 

      Hollerbach, John M.; Flash, Tamar (1981-11-01)
      Movement of multiple segment limbs requires generation of appropriate joint torques which include terms arising from dynamic interactions among the moving segments as well as from such external forces as gravity. The ...

    • Dynamic Load Balancing with Group Communication 

      Dolev, Shlomi; Segala, Roberto; Shvartsman, Alexander A. (1999-10)
      This work considers the problem of efficiently performing a set of tasks using a network of processors in the setting where the network is subject to dynamic reconfigurations, including partitions and merges. A key challenge ...

    • Dynamic Model and Control of an Artificial Muscle Based on Contractile Polymers 

      Brock, David L. (1991-11-01)
      A dynamic model and control system of an artificial muscle is presented. The artificial muscle is based on a contractile polymer gel which undergoes abrupt volume changes in response to variations in external conditions. ...

    • Dynamic Module Replacement in a Distributed Programming System 

      Bloom, Toby (1983-03)
      The replacement of parts of software systems is an important aspect of programming methodology. Most of the research in this area has centered around support for modular construction and the clear separation of interface ...

    • Dynamic Prefetching of Data Tiles for Interactive Visualization 

      Battle, Leilani; Chang, Remco; Stonebraker, Michael (2015-10-19)
      In this paper, we present ForeCache, a general-purpose tool for exploratory browsing of large datasets. ForeCache utilizes a client-server architecture, where the user interacts with a lightweight client-side interface to ...

    • A Dynamic Primary View Group Communication Service 

      De Prisco, Roberto; Fekete, Alan; Lynch, Nancy A.; Shvartsman, Alexander A. (2002-11)

    • Dynamic Programming on Graphs with Bounded Treewidth 

      Bodlaender, Hans L. (1987-06)
      In this paper we study the complexity of graph decision problems, restricted to the class of graphs with treewidth k, (or equivalently, the class of partial k-trees), for fixed k. We introduce two classes of graph ...

    • Dynamic Reconfiguration in a Modular Computer System 

      Schell, Roger R. (1971-06)
      This thesis presents an orderly design approach for dynamically changing the configuration of constituent physical units in a modular computer system. Dynamic reconfiguration contributes to high system availability by ...

    • Dynamic Scaling of Manipulator Trajectories 

      Hollerbach, John M. (1983-01-01)
      A fundamental time-scaling property of manipulator dynamics has been identified that allows modification of movement speed without complete dynamics recalculation. By exploiting this property, it can be determined ...

    • The Dynamic Structure of Everyday Life 

      Agre, Philip E. (1988-10-01)
      Computational theories of action have generally understood the organized nature of human activity through the construction and execution of plans. By consigning the phenomena of contingency and improvisation to ...

    • Dynamical Systems and Motion Vision 

      Heel, Joachim (1988-04-01)
      In this paper we show how the theory of dynamical systems can be employed to solve problems in motion vision. In particular we develop algorithms for the recovery of dense depth maps and motion parameters using state ...

    • A Dynamical Systems Model for Language Change 

      Niyogi, Partha; Berwick, Robert (1995-12-01)
      Formalizing linguists' intuitions of language change as a dynamical system, we quantify the time course of language change including sudden vs. gradual changes in languages. We apply the computer model to the historical ...

    • Dynamically Reparameterized Light Fields 

      Isaksen, Aaron; McMillan, Leonard; Gortler, Steven J.

    • Dynamically Resizable Static CMOS Logic for Fine-Grain Leakage 

      Heo, Seongmoo; Asanovic, Krste (2004-07-12)
      Digital circuits often have a critical path that runs through a smallsubset of the component subblocks, but where the path changes dynamicallyduring operation. Dynamically resizable static CMOS (DRCMOS) logic isproposed ...

      This report documents our work in exploring active balance for dynamic legged systems for the period from September 1985 through September 1989. The purpose of this research is to build a foundation of knowledge that ...

    • The Dynamicist's Workbench: I Automatic Preparation of Numerical Experiments 

      Abelson, Harold; Sussman, Gerald Jay (1987-05-01)
      The dynamicist's workbench is a system for automating some of the work of experimental dynamics. We describe a portion of our system that deals with the setting up and execution of numerical simulations. This part of ...
