      Euterpe is a real-time computer system for the modeling of musical structures. It provides a formalism wherein familiar concepts of musical analysis may be readily expressed. This is verified by its application to the ...
    • Parallelism in Manipulator Dynamics 

      Lathrop, Richard D. (1984-12-01)
      This paper addresses the problem of efficiently computing the motor torques required to drive a lower-pair kinematic chain (e.g., a typical manipulator arm in free motion, or a mechanical leg in the swing phase) given ...
    • A Parallelizing Compiler Based on Partial Evaluation 

      Surati, Rajeev (1993-07-01)
      We constructed a parallelizing compiler that utilizes partial evaluation to achieve efficient parallel object code from very high-level data independent source programs. On several important scientific applications, ...
    • Parameter Estimation in Chaotic Systems 

      Hung, Elmer S. (1995-04-01)
      This report examines how to estimate the parameters of a chaotic system given noisy observations of the state behavior of the system. Investigating parameter estimation for chaotic systems is interesting because of ...
    • Passive and Active Grasping with a Prehensile Robot End-Effector 

      Greiner, Helen (1990-05-01)
      This report presents a design of a new type of robot end-effector with inherent mechanical grasping capabilities. Concentrating on designing an end-effector to grasp a simple class of objects, cylindrical, allowed a ...
    • Passive Dynamics in the Control of Gymnastic Maneuvers 

      Playter, Robert (1995-03-01)
      The control of aerial gymnastic maneuvers is challenging because these maneuvers frequently involve complex rotational motion and because the performer has limited control of the maneuver during flight. A performer can ...
    • Performance Evaluation of the Scheme 86 and HP Precision Architecture 

      Wu, Henry M. (1989-04-01)
      The Scheme86 and the HP Precision Architectures represent different trends in computer processor design. The former uses wide micro-instructions, parallel hardware, and a low latency memory interface. The latter ...
    • The PHD: A Planar, Harmonic Drive Robot for Joint Torque Control 

      Thompson, Bruce R. (1990-05-01)
      This thesis details the development of a model of a seven degree of freedom manipulator for position control. Then, it goes on to discuss the design and construction of a the PHD, a robot built to serve two purposes: ...
    • Pi: A Parallel Architecture Interface for Multi-Model Execution 

      Wills, Donald Scott (1990-05-01)
      This thesis defines Pi, a parallel architecture interface that separates model and machine issues, allowing them to be addressed independently. This provides greater flexibility for both the model and machine builder. ...
    • Piezoelectric Ultrasonic Micromotors 

      Flynn, Anita M. (1995-06-01)
      This report describes development of micro-fabricated piezoelectric ultrasonic motors and bulk-ceramic piezoelectric ultrasonic motors. Ultrasonic motors offer the advantage of low speed, high torque operation without ...
