(Texas A&M University, 1993)The objective of this thesis is to evaluate the performance of block codes that are designed to be rotationally invariant, in a multilevel coding scheme, over a channel modelled to be white gaussian noise. Also, the use ...

(Texas A&M University, 1993)A finite-element-based perturbation model, initially developed for straight annular seals, has been extended to the labyrinth seal problem. The rotordynamic coefficients for two different labyrinth seal configurations, ...

(Texas A&M University, 1997)Hybrid bearings (combinations of hydrostatic and hydrodynamic bearings) represent an attractive alternative to ball bearings for use in high-speed cryogenic turbopumps. However, the internally-developed cross-coupled forces ...
-
(Texas A&M University, 1998): : Issued also on microfiche from Lange Micrographics. For future high-speed cryogenic turbomachinery, ball bearings will be replaced by hybrid bearings that combine hydrostatic and hydrodynamic effects. Hybrid bearings ...
-
(Texas A&M University, 2000)Two hole-pattern seals are compared with one smooth bore seal. The two hole-pattern seals have cell depths of 2.03 mm and 3.18 mm with a cell diameter of 1.59 mm. The hole area density factor for both hole-pattern seals ...
-
(Texas A&M University, 2003)Metal mesh hybrid damper seals (MHS) were proposed to be an alternative for brush hybrid pocket damper seals (PDS) in turbomachinery. The metal mesh hybrid damper seal is a hybrid of the pocket damper seal and the metal ...
-
(Texas A&M University, 1998)A basic rotordynamic model is developed for an crographics. unbalanced rotor connected to a shaft modeled as a continuous beam. This model examines the effects of nonlinear dynamics strictly related to the rotor and shaft. ...

(Texas A&M University, 1993)The effect of bus route names on elderly transit riders' route-finding performance was investigated. A survey of public transit companies indicated that most identify routes with names and numbers, plus color coding, and ...
-
(Texas A&M University, 1999)The goal of this thesis is to analyze the dynamic behavior of a given nonlinear system and then control the chaotic behavior of the system within some ranges of the parameters. In the first part of this thesis, we study ...
-
(Texas A&M University, 1997)Current videoconferencing applications operating on packet networks do not have the capability to gauge the available network capacity prior to requesting additional quality by subscribing to enhancement layers. To minimize ...
