Development and study on the generalized geometric model for robot calibration
(1991)
Accuracy improvement in the processes of robot calibration depends heavily on the models that represent the robots. This dissertation is about the development and evaluation of the so-called general model. Unlike any ...
Test and theory for robust active vibration control of rotor- bearing systems utilizing piezoelectric actuators
(1993)
This research focuses on designing effective control strategies using piezoelectric actuators for control of vibrations of flexible rotor-bearing systems. The actuators are completely described and the elements of feedback ...
A numerical analysis of convective heat transfer in channels simulating electronic components
(1993)
The cooling performance of two dimensional channel flow simulating channels of electronic components has been studied numerically. A channel is formed with the substrates on which the heat sources are surface-mounted ...
Modeling the effects of refrigerant charging on air conditioner performance characteristics for three expansion devices
(1990)
An experimental and analytical study concerned with the off-design refrigerant charging of air conditioners is presented. A series of experiments were conducted to characterize the effects of refrigerant charge and type ...
A three-dimensional viscous flow model of stator/rotor interaction in turbomachines
(1990)
The current numerical model takes into account the full three-dimensionality and cyclic fluctuations of the flow variables in a turbomachinery stage. The cyclic fluctuations are the result of circumferential irregularities ...
Development of a cycle simulation for a coal-fueled, direct-injected, internal combustion engine
(1986)
An engine cycle simulation for a coal-fueled internal combustion, reciprocating engine was developed. The primary objective of this work was to develop the simulation for evaluating the viability of coal fuels for engines. ...
Modeling laminates using a layerwise finite element with enhanced strains for interlaminar stress recovery and delamination characteristics
(1997)
A layerwise finite element with enhanced strains is developed for the analysis of laminates with special emphasis on the recovery of interlaminar stresses and the study of delamination characteristics. A laminate interface, ...
Turbulence characteristics of an incompressible free jet under the influence of acoustic disturbances
(1988)
An acoustically excited (St = 0.50), Mach 0.15, axisymmetric free jet operating at Reynolds number of 41,000 was studied in order to determine the transition behavior, the overall turbulence characteristics, and to quantify ...
Turbulent heat transfer enhancement in rectangular channels with two opposite rib-roughened walls
(1986)
This work presents the results of an experimental investigation into the effects of variations in the channel aspect ratio and rib angle-of-attack, on the friction factor and local heat transfer in rectangular channels ...
Finite element analysis of crack growth in inelastic media
(1986)
In most materials, macrocrack extension is accompanied by inelastic phenomena (such as microcracking or plastic deformation) throughout a region surrounding the crack tip. Immediately ahead of the crack tip, strain ...
