Stochastic analysis of complex nonlinear system response under narrowband excitations

Creator:: Shih, I-Ming
Abstract:: Response behavior of a nonlinear structural system subject to environmental loadings is investigated in this study. The system contains a nonlinear restoring force due to large geometric displacement. The external excitation is modeled as a narrowband stochastic process possessing dynamic characteristics of typical environmental loadings. A semi-analytical method is developed...

Stochastic analysis of a nonlinear ocean structural system

Creator:: Lin, Huan
Abstract:: Stochastic analysis procedures have been recently applied to analyze nonlinear dynamical systems. In this study, nonlinear responses, stochastic and/or chaotic, are examined and interpreted from a probabilistic perspective. A multi-point-moored ocean structural system under regular and irregular wave excitations is analytically examined via a generalized stochastic Melnikov function and Markov...

Nonlinear approach to the direction finding problem in array processing

Creator:: Ill-keun Rhee
Abstract:: In sonar or radar array processing, one of the most important objectives is to estimate the angles of incidence of distant source signals in a noisy environment. The standard eigenstructure-based method, which is known to yield high resolution spectral estimates for solving the direction finding problem, relies on the assumption...

Spectral analysis and ridge-regression of magnetic anomalies from the northern continental margin of the Yucatán Peninsula, Mexico

Creator:: Garcia-Abdeslem, Juan
Abstract:: Marine magnetic data from the northern Yucatan continental margin were used to obtain the radially-averaged power-density spectra (RAPDS) of 34 grids, each with dimensions of 128 by 128 km, overlapping 50 percent. Depths to the tops of three magnetic horizons were estimated from the slopes of linear segments in the...

The 1988 Lancang-Gengma, China, earthquake sequence : teleseismic body wave, surface wave and strong ground motion studies

Creator:: Li, Xiao-qing, 1963-
Abstract:: On November 6, 1988, two strong earthquakes (Mw: 7.0 and 6.8) separated by about 13 minutes occurred in Yunnan Province, China. The aftershocks located by Kunming Telemetered Seismic Network form a lineament approximately 120 km long and 20 km wide with the long dimension oriented approximately N30°W. The epicenter of...

Finite difference wavefield modeling of large-aperture data from the 1993 Mendocino Triple Junction Seismic Experiment

Creator:: Lendl, Christof
Abstract:: This thesis presents elastic finite difference simulations of two dimensional wavefield propagation for line-9, recorded during the 1993 part of the multi-institutional, multi-year Mendocino Triple Junction (MTJ) Seismic Experiment. Line-9 is a high-resolution, large-aperture seismic profile oriented in north-south direction, extending from the subduction regime north of the MTJ to...
