The anchor-last mooring procedure is investigated in order to determine the transient forces in the mooring line and the velocities of the anchor. Transient forces were determined and the results showed that no severe snap loads occurred for the cases investigated. In addition, it was found that the vertical velocity...
This study links together two very complicated, but very important subjects: media bias and metaphor. More specifically, this study investigates whether or not examining a media outlet's use of metaphor is an effective methodology for investigating media bias. Using cluster analysis, I identified the source metaphors most commonly used on...
This paper describes the results of a project conducted to determine
the magnitude of and the parameters affecting the magnitude of the
cable tensions generated during lateral yarding operations in a cable
thinning. Specific emphasis was placed on measuring mainline tensions
as a function of turn weight, turn length, mainline...
As interest grows in developing devices to harvest energy from ocean waves, tidal currents, and offshore wind, concerns over possible environmental effects from such devices also grow. One such concern is over the induced electric fields and the generated magnetic fields from generators and their associated submarine power cables in...
Achieving and maintaining sustainability in irrigated agriculture production in the era of rapidly increasing stress on our natural resources require, among other essential actions, optimum control and management of the applied water. Thus, a significant upgrade of the currently available soil water monitoring technologies is needed. The primary goal of...
Time-domain models were developed to predict the response of a tethered buoy
subject to hydrodynamic loadings. A coupled analysis of the interaction of a buoy and
its mooring is included and three-dimensional response is assumed. External loadings
include hydrodynamic forces, tethers tensions, wind loadings and the weight of both
cable...
The dissertation uses state-of-the-art structural engineering theories, in parallel with the modern and still-developing control theory of electrical engineering to mitigate the vibratory responses of a double-stayed bridge subjected to strong earthquake ground motions.
First, a nonlinear finite element model of the double-stayed bridge subjected to non-uniform (multi-support) earthquake excitations...
An optimization methodology, algorithms, and computer program for
cable/lumped-body deployment system are developed for the design and installation of
sonar packages in deep ocean ranges. In addition, a methodology and algorithms for the
control of the system are proposed.
A penalty function is developed in terms of the system parameters...
