(2019-11-20)The effect of SST mesoscale variability on the dynamics of the North Pacific Jet Stream and Storm track is investigated based on simulations with a global atmospheric circulation model coupled to a slab ocean model. The ...
-
(Texas A&M University. Libraries, 1988)A new analysis procedure which solves for leakage, reactive force, and rotordynamic coefficients of eccentric annular liquid and gas pressure seals is presented in this dissertation. This analysis procedure is based on a ...
-
(2017-12-04)Data are available for a previously tested annular seal with no swirl brakes (NSB). The NSB seal design was modified by adding slots at the inlet to produce a swirl brake (SB) seal. Tests were conducted to evaluate the ...
-
(Texas A&M University. Libraries, 1992)This dissertation presents a family of computationally efficient methods for the simulation of large, flexible multibody systems. Non-recursive order N formulations for the transient dynamic analysis of multibody systems ...
-
(2014-08-05)The work is divided into two parts: The First part discusses and documents simulation investigations on the interactive effect of the different conveyance accessories tools and their designs on the wireline cable tension ...
-
(2022-11-07)Kerfing is a subtractive manufacturing method to create flexible surfaces from stiff planar materials. While the kerf structures are ubiquitous in indoor and outdoor architectures due to their pleasing aesthetics, they ...
-
(2012-02-14)In order to rationally optimize a reaction, it is necessary to have a thorough understanding of its mechanism. Consequently, great effort has been made to elucidate a variety of reaction mechanisms. However, the fundamental ...
-
(Texas A&M University. Libraries, 1993)The purpose of this research is to investigate the dynamics of a tethered satellite system in which the flexibility of the tether is considered and to design control laws for the deployment and retrieval of the tethered ...
-
(2011-02-22)Knowledge of energy dissipation and relaxation in electron, spin, and lattice degrees of freedom is of fundamental importance from both a technological and scientific point of view. In this dissertation, the electronic and ...
-
(Texas A&M University. Libraries, 1988)The Mach number definition and boundary conditions in Nelson's nominally-centered, annular gas seal analysis are revised. A method is described for determining the wall shear stress characteristics of an annular gas seal ...
-
(2012-10-19)The estimation approaches examined in this dissertation focus on manipulating system dynamical models to allow the well-known form of the continuous-discrete extended Kalman filter (CDEKF) to accommodate constrained and ...
-
(2019-11-22)Squeeze film dampers (SFDs) in high-performance turbomachinery reduce rotor motion amplitudes as it traverses a critical speed or when the system has a dynamic instability, thus ensuring system reliability. To improve the ...
-
(2018-11-26)Accurate modeling and analysis approaches have long been important concerns for designers of rotating machinery. This work is focused on the improvement of high-fidelity finite element (FE) modeling approaches and software ...
-
(Texas A&M University. Libraries, 1984)By employing the extended Hamilton principle, both equations of motion and associated boundary conditions are derived for three different models subjected to non-conservative torques: the cantilevered rotor, the uniform ...
-
(Texas A&M University, 2007-04-25)The structure and function of RNA molecules are dependent on RNA-metal ion interactions in both diffusive and direct ways. Structural information for RNA has been obtained using various biophysical and biochemical methods. ...
-
(Texas A&M University. Libraries, 1989)The positional isotope exchange (PIX) technique has been used to investigate the mechanisms of five enzymes: uridine diphosphoglucose pyrophosphorylase, galactose 1-phosphate uridyltransferase, sucrose synthetase, D -alanyl-D ...
-
(Texas A&M University, 2005-08-29)As the cost of land in cities increases, the need to build multistory buildings in close proximity to each other also increases. Sometimes, construction materials, other objects and any projections from a building may ...
-
(Texas A&M University. Libraries, 1980)This dissertation considers the problem of the foundation force of an unbalanced rotating machine from both deterministic and probabilistic viewpoints. The rotor-housing is modeled as a three degree-of-freedom system wherein ...
-
(2013-04-30)Reinforcement Learning has received a lot of attention over the years for systems ranging from static game playing to dynamic system control. Using Reinforcement Learning for control of dynamical systems provides the benefit ...
-
(2009-06-02)Fresh water resources in many of the world's oil producing regions, such as western Texas, are scarce, while produced water from oil wells is plentiful, though unfit for most applications due to high salinity and other ...
