A phenomenological model for rarefied gas flows in thin film slider bearings
(Texas A&M University, 2002)
We analyze rarefied gas flows in lubricating films that form between the read/write head and rotating recording medium in computer hard drives. A modified slip-corrected Reynolds lubrication equation is derived for arbitrary ...
The study and characterization of the major flow through rectangular slit virtual impactor
(Texas A&M University, 2002)
The major flow through a rectangular slit virtual impactor was experimentally studied. The impactor was a two-dimensional rectangular slit dichotomous sampler. A series of experiments were performed using monodisperse ...
Real-time implementation of a neural networks-based motor speed filter using a digital signal processor
(Texas A&M University, 2002)
Induction motors play a vital industrial role. In many industrial applications, it is desirable to eliminate the use of motor speed sensors, which increase the size and cost while reducing the mechanical robustness of the ...
Line map construction based on small-scale mobile robot using single-sonar navigation
(Texas A&M University, 2002)
The objective of this study is to represent a way to construct a line map for an unknown indoor mobile robot environment based on a sonar sensor. The proposed procedure consists of two main steps. In the first step the ...
Investigation of polarization spectroscopy for detecting atomic hydrogen in flames
(Texas A&M University, 2002)
Two-color, two-photon, laser-induced polarization spectroscopy (LIPS) of atomic hydrogen has been demonstrated for the first time. The pump beam in the measurements was tuned to the two-photon 243-nm n = 1 --> n = 2 ...
Design and fabrication of a maglev linear actuator capable of nanopositioning
(Texas A&M University, 2002)
This thesis presents the design and fabrication of a novel magnetically levitated (maglev) linear actuator. The linear actuator has a linear positioning range of ł250 mm. It will act as a unit actuator in a six-degrees-of-freedom ...
Discrimination among mechanical fault types in induction motors using electrical measurements
(Texas A&M University, 2002)
Rotating machine failures are a major cause of downtime in a wide variety of industrial processes and are a burden on maintenance personnel and facilities. Some of these failures occur suddenly and are seemingly unpredictable. ...
A Rugged Continuous Air Monitor for Sampling Radionuclides
(Texas A&M University, 2002)
A new rugged continuous air monitor (CAM) for sampling radionuclide has been developed. The sampler was designed for analyzing aerosols from occupied environments of laboratories and samples extracted from stacks and ...
A quantitative and objective evaluation approach for optimal selection of design concept in conceptual design stage
(Texas A&M University, 2002)
The need exists for developing quantitative tools to quantify design information much earlier in the conceptual design stage. This will help in making a prudent, confident and concrete selection among the available design ...
Adaptive control of media applications in best-effort networks using reliable transport protocols
(Texas A&M University, 2002)
Quality of Service (QoS) in continuous media applications is an area of current interest because of the increased delivery of stored and live media over packet-switched computer networks. Media applications are transported ...
