Distributed System Simulation With Bilateral Delay-Line Models
(The American Society of Mechanical Engineers (ASME), 1968)Consideration of general linear models for transmission line systems (hydraulic, pneumatic, electrical, etc.) has so far been limited to the case of systems in which the lines exhibit no internal ... -
Modeling and Compensation of Nonlinear Systems Using Sensitivity Analysis
(The American Society of Mechanical Engineers (ASME), 1968)In this paper sensitivity analysis techniques are applied to two aspects of the nonlinear system design problem: The modeling of nonlinear systems and the compensation of nonlinear systems. In ... -
On the Optimal-Control Problem for Dynamical Processes With Variable Delays
(The American Society of Mechanical Engineers (ASME), 1968)The principles of calculus of variations are used to obtain necessary conditions for optimal control of dynamical systems that involve nonconstant time lags. Consideration is given to systems ... -
Investigation of Feedback Controlled Diffusion Systems Using a High-Speed Continuous Electrical Analog
(The American Society of Mechanical Engineers (ASME), 1968)A high-speed, two-dimensional, nonsteady, electrical diffusion analog is discussed with emphasis on applications to heat conduction systems. The accuracy of the device is apparent from transfer ... -
An Active Roll Mode Suspension System for Ground Vehicles
(The American Society of Mechanical Engineers (ASME), 1968)This paper describes an automatic roll mode control system for ground vehicles. The primary objective of the so-called “active suspension system” is to maintain a coordinated vehicle banking ... -
Application of Distributed Parameter Concepts to Dynamic Analysis and Control of Bending Vibrations
(The American Society of Mechanical Engineers (ASME), 1968)As an alternative to the normal vibration mode approach to dynamic analysis and control of bending vibrations, such vibrations are studied in terms of the distributed parameter concepts of ... -
Dynamic Programming and a Distributed Parameter Maximum Principle
(The American Society of Mechanical Engineers (ASME), 1968)A proof of a distributed parameter maximum principle is given by using dynamic programming. An example problem involving a nonhomogeneous boundary condition is also treated by using the dynamic ... -
A Differential Pulse-Length Modulated Pneumatic Servo Utilizing Floating-Flapper-Disk Switching Valves
(The American Society of Mechanical Engineers (ASME), 1968)A novel approach to gas servo design is presented which provides closed-center operation while eliminating close clearance sliding seals and elastic members. Pulse-length modulated pressure waves ... -
Incompressible Turbulent Flow in the Inlet Region of a Pipe
(The American Society of Mechanical Engineers (ASME), 1968) -
Effect of State-of-Stress and Yield Criterion on the Bauschinger Effect
(The American Society of Mechanical Engineers (ASME), 1968)During fabrication, the cold forming of structural components may reduce the yield strength of a component if it is loaded in a direction opposite to that of the cold forming. This reduction ... -
On the Shock Wave Velocity and Impact Pressure in High-Speed Liquid-Solid Impact

Development of a Periodic Flow in a Rigid Tube
(The American Society of Mechanical Engineers (ASME), 1968)The development of a pulsating velocity field in a rigid, circular tube was experimentally investigated. The wall pressure and the radial variation of the axial velocity were measured at several ... -
Nonlinear Interaction of Two Lifting Bodies in Arbitrary Unsteady Motion
(The American Society of Mechanical Engineers (ASME), 1968)A Method is developed for the exact calculation of the two-dimensional potential flow about two bodies, either or both of which are lifting, in nonlinear-unsteady flight. No restrictions are ... -

Interaction of a Sloshing Liquid With Elastic Containers
(The American Society of Mechanical Engineers (ASME), 1968)The coupled oscillations of a liquid partially filled container having an elastic bottom or elastic walls have been studied. Two different tank configurations, a rectangular and a circular ... -
Velocity Distributions in Two-Phase Vortex Flow
(The American Society of Mechanical Engineers (ASME), 1968)An analytical model is developed to describe gas-jet driven two-phase vortex flow. Utilizing experimental data, the model is used to calculate the velocity distributions of the two phases within ... -
Jet Impact and Cavitation Damage
(The American Society of Mechanical Engineers (ASME), 1968)On the basis of presently known erosion theories, an analogy is made between jet impact and cavitation erosion, and confirmed by experiments. As a consequence of this analogy, data on jet ... -
The Dynamics of a Heated Free Jet of Variable Viscosity Liquid at Low Reynolds Numbers
(The American Society of Mechanical Engineers (ASME), 1968)To spin polymers or glass into continuous fibers, molten material is forced through a nozzle into air forming a free liquid jet. The jet is cooled as it proceeds through the air and the ... -
Creeping Flow Through an Axisymmetric Sudden Contraction or Expansion
