Creator:: McCullough, Nason J.
Abstract:: This dissertation presents the results of a research effort conducted to better understand the seismic performance and analysis of pile-supported wharves. Given the limited number of well-documented field case histories, the seismic performance of pile-supported wharves has been poorly quantified, and the analysis methods commonly employed in engineering practice have...

Creator:: Kawamata, Yohsuke
Abstract:: Recently, the concept of performance based design has become popular for many types of structures, including port facilities under seismic loading. For the case of pile-supported wharves, the level of performance is generally estimated using the displacement capacity of the structure. Therefore, understanding soil-pile interaction is one of the most...

Creator:: Yuk, Dongjun
Abstract:: A numerical model for the simulation of fully-coupled fluid-structure interaction is developed in this study. In modeling the fluid, the Reynolds Averaged Navier-Stokes equations are solved for an incompressible viscous fluid field and a k-ε model is employed for turbulence computations. Hydrodynamic forces obtained by the integration of the fluid...

Creator:: Stapels, Christopher John
Abstract:: As part of a research program to study the transitional region of N=88 isotones, ¹⁵²Tb was produced by the reaction ¹⁵¹Eu(α,3n)¹⁵²Tb in the 88" cyclotron located at LBNL. Gamma-ray spectroscopy of the radiation emitted from excited ¹⁵²Gd following the β⁺ decay of ¹⁵²Tb has been performed using an array of...

Creator:: Agamloh, Emmanuel B.
Abstract:: Commonly proposed ocean wave energy converters (OWEC) use inefficient and maintenance demanding intermediate hydraulic and pneumatic systems. We propose a novel rotary direct-drive OWEC that eliminates these intermediate stages. The new device employs a contactless force transmission system (CFTS) comprising a “piston” and a “cylinder” and a ball screw to...

Creator:: King, Paul E.
Abstract:: Complex oscillations including chaotic motions have been identified in off-shore and submerged mooring systems characterized by nonlinear fluid-structure interactions and restoring forces. In this paper, a means of controlling these nonlinear oscillations is addressed. When applied, the controller is able to drive the system to periodic oscillations of arbitrary periodicity....
