Measurement of the Heat Capacities of Pure and Mixed Refrigerants

June 20, 1988
Author(s)
R Radermacher
A flow calorimeter was designed and built to measure the heat capacity of pure and mixed halogenated hydrocarbons in the liquid phase. The calorimeter is an electrically heated, coiled tube located inside a vacuum chamber in the water bath. The liquid

Analysis and Prediction of Air Leakage Through Door Assemblies

June 9, 1988
Author(s)
Daniel Gross, W L. Haberman
A generalized relationship is presented for determining air flow rates through narrow gaps around door edges. The relationship provides values of leakage rates for steady, laminar flow through gaps over a wide range of pressure differences and eliminates

Optimal Control of a Flexible Robot Arm

June 1, 1988
Author(s)
Jonathan W. Lee, B Wang
The work is a computer simulation of the control of a flexible robot arm. The dynamic equations for a single-link flexible robot arm have been derived rigorously. This arm has two degrees of freedom in rotation and one in translation so that the workspace

Performance Measures of a Robotic Micropositioner

June 1, 1988
Author(s)
Jonathan W. Lee, James S. Albus, Nicholas G. Dagalakis, T M. Tsai
This work describes a computer simulation of the dynamics and control of a robotic micropositioner. The robotic micropositioner is a parallel link manipulator which has six actuators, each controlled independently by a hydraulic system. The dynamic
