A new objective function for robot calibration
(1994)
When using a robot, the operator usually desires to locate the tool accurately. To accomplish this, the operator should measure the tool position then use feedback to "drive" the manipulator in such a way that the tool ...
Microstructure and mechanical properties of aluminum 5083 processed by equal channel angular extrusion
(1999)
The objectives of this research were to process commercial Al - 5083 using equal channel angular extrusion routes A, B, and C, include intermediate solution-heat treatments, investigate the room temperature and superplastic ...
The experimental implementation and comparison of active, semiactive, and passive vehicle suspensions utilizing a linear electric motor
(Texas A&M University, 1994)
The primary objective of this research is the investigation of the experimental implementation of an active automobile suspension, three types of semiactive suspensions, and a passive suspension. These suspensions are ...
Jet impingement heat transfer in rotating coolant passages
(1995)
In gas turbine engines, increasing turbine inlet temperature increases engine thermal efficiency but also increases the amount of heat transferred to the turbine blades. To achieve reasonable turbine blade durability ...
Development of axial compressor and turbine simulation modules for integration into the dynamic simulation code GETRAN
(1995)
New one-dimensional methods of axial compressor and turbine design and off-design performance calculations are presented. The calculations may be carried out at various levels of complexity, depending on the available ...
Capillary performance and heat transfer charateristics of the evaporating thin liquid film in a triangular micro groove
(1995)
For the capillary flow in a groove channel, the analysis of axial variation of the intrinsic meniscus as well as that of evaporating thin film region was carried out. Various approximate analytical solutions were developed ...
Synthesis of compensators for non-overshooting step responses
(1992)
In many physical systems, a non-overshooting step response is often desirable if not required. Presented in this dissertation is a general design methodology for synthesizing compensators for a non-overshooting step response ...
A design methodology for synthesizing low order robust controllers for flexible structures
(1992)
In this research, a design methodology is developed for realizing low order robust controllers for flexible structures modelled as partial differential equations (PDEs). The efficacy of the methodology is illustrated by ...
Nonlinear dynamic system identification using recurrent neural networks
(1993)
The objective of this research is to develop a nonlinear empirical model structure and an associated parameter estimation algorithm based on artificial neural networks (ANNs), and to further use it for the identification ...
Modeling delamination characteristics and influence in a laminated plate with a part-through hole
(1993)
A laminated composite pressure vessel subjected to a concentrated laser ablation process has been investigated. The primary goal of this research was to investigate the role of delamination in the failure process. A layered ...
