Fixed bed gasification studies on coal-feedlot biomass and coal-chicken litter biomass under batch mode operation
(Texas A&M University, 2002)
In the U.S. alone, approximately 200 million tons of dry cattle waste are being produced annually. Recently, cattle and poultry manure have been classified as biomass fuels and have been identified as sources of renewable ...
Characterization of residual stress relaxation in welded steel plate using TAP-NDE and wavelets
(Texas A&M University, 2001)
This thesis presents the characterization of residual stress relaxation in a welded ASTM 1018 steel plate by using the Thermo-Acousto-Photonic Nondestructive Evaluation (TAP-NDE) technique and the Gabor Wavelet Transform ...
Impact fracture behavior of model system modified polypropylene
(Texas A&M University, 2000)
The morphology and impact properties of polypropylene copolymer blends modified with talc and/or ethylene-propylene (EPR) or ethylene-octene (EOR) rubber were studied. Izod impact, instrumented Charpy impact, and high ...
A continuous emission monitor for quantitative measurement of PM10 emissions from stationary sources
(Texas A&M University, 2000)
A continuous emission monitoring system has been developed for accurate measurement of PM₁₀ dust mass concentration in a stack environment. Using an EPA Method 201A cyclone, the system continuously extracts a particulate ...
The effects of moisture and particle size of feedlot biomass on co-firing burner performance
(Texas A&M University, 2001)
Biomass (conventional and non-conventional) fuels co-fired with coal for power and steam generation are being tested and evaluated at several generation stations in the United States. The co-firing technology is expected ...
Flow reactor experiments on the selective non-catalytic removal of nitrogen oxides
(Texas A&M University, 2001)
Three flow reactor studies, using an electrically heated laminar flow reactor, were performed at 1 atm pressure and various temperatures. To establish inert conditions inside the reactor, a quartz tube was used. The ...
Concurrent design and optimization of a star tracker for space applications by identification of critical design parameters and their effect on a performance measure
(Texas A&M University, 2001)
An optimization procedure to be used concurrently with a top-down general design process was developed. The optimization procedure consists of identifying the critical design parameters and analyzing their effect on a ...
A study on the isothermal elastic response of inhomogeneous materials for certain classes of boundary value problems
(Texas A&M University, 2001)
In this work, a systematic study of the solution to classes of boundary value problems when the body is inhomogeneous is undertaken. Within the framework of field theories, the non-linear equations, describing the isothermal ...
Genetic algorithm based optimization in engineering design using fuzzy constraints and fitness functions
(Texas A&M University, 2001)
The motivation for this work has been the use of tools, such as genetic algorithms and fuzzy sets, to address the various issues that are involved in an engineering design optimization problem. In order to address the ...
The experimental determination of the dynamic radial stiffness of an angular contact ball bearing
(Texas A&M University, 2001)
To evaluate the A. B. Jones bearing stiffness predictions on an angular contact ball bearing, experimental testing on an angular contact ball bearing was conducted. Objectives of the testing were to determine the effects ...
