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 ...
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, ...
Study of air infiltration energy consumption
(1992)
The influence of heat recovery on the energy impact of air infiltration, and the systematic error due to the steady-state method were studied both experimentally and theoretically. Two methodologies suitable for measurement ...
A generalized methodology for manufacturability evaluation
(1993)
In a design for manufacturing (DFM) approach the designer has to consider the interactions between the various parameters in the design and the ease with which it can be manufactured, very early in the design process. This ...
Particle lift force and particle behavior in suspension flows
(1994)
In this study, particle lift force and its influence on particle behavior are considered in suspension flows. Saffman force, a particle lift force derived in parallel laminar shear flow, is extended to a general particle ...
A methodology to measure retrofit energy savings in commercial buildings
(1993)
Measured energy savings promote and sustain energy conservation retrofits by verifying the success of retrofits, determining pay-back schedules, guiding the selection of future retrofits and identifying opportunities for ...
