A motion planner for a redundant mobile manipulator using the inverse kinematics
(Texas A&M University, 2003)
This thesis is an effort to develop a powerful motion-planning algorithm for the mobile manipulator. The mobile manipulator is expected to work in partially defined or unstructured environments. In global/local approach, ...
A simplied approach for generating frequency domain bounds for QFT designs
(Texas A&M University, 1998)
(QFT) design methodology for multiple feedback controllers can be difficult and tedious. The procedure involves uncoupling the system into a series of single input-single output (SISO) designs. This, at times, requires the ...
Investigation of spark discharge processes and ignition systems for spark-ignited internal combustion engines
(Texas A&M University, 2000)
Spark ignition of the air-fuel mixture at the appropriate time is important for successful flame initiation and complete combustion thereafter without unnecessary emissions. The physical and chemical reactions taking place ...
Experiments on the reduction of nitric oxide from exhaust gases by selective non-catalytic reactions
(Texas A&M University, 1993)
The use of ammonia in a selective non-catalytic process for the removal of nitric oxide (NO) from exhaust gases was studied. A quartz lined flow reactor system was constructed in order to examine the behavior of the process ...
Experimental study of rotordynamic coefficients of squeeze film dampers of an aircraft gas turbine engine
(Texas A&M University, 1996)
The rotordynamic coefficients of squeeze film dampers of an aircraft gas turbine engine were investigated experimentally. Rotordynamic model(XLROTOR) for Gas Generator and Power Turbine were constructed. The XLROTOR ...
Jet impingement heat transfer in two-pass rotating rectangular channels
(Texas A&M University, 1996)
The combined effects of rotation and jet impingement on local heat transfer in a two-pass rotating rectangular channel is studied. The results of an experimental investigation on the surface heat transfer coefficients under ...
The static and dynamic characteristics of divergent tapered-bore hole-pattern gas seals
(Texas A&M University, 2001)
Experimental data is presented for three hole-pattern annular gas seals with differing diverging tapers machined in them. The holes are approximately 3.12 mm (.123 in) deep on average with a hole area to surface area ratio ...
Optimization of cutting parameters in end milling using tool life as an objective function
(Texas A&M University, 2001)
In any manufacturing industry there is a constant urge to improve upon existing conditions, a concept the Japanese aptly term Kaizen. Improvements are essentially a steppingstone to increased profit margin, better quality ...
Effect of shrink fits on threshold speeds of rotordynamic instability
(Texas A&M University, 2001)
An investigation of the effect of shrink fits on threshold speeds of rotordynamic instability has been performed. It is known that running rotors at supercritical speed can result in some rotordynamic problems (asynchronous ...
