The framework of the studies presented in this thesis is the one-dimensional power spectrum of the transmitted flux in the Lyman-alpha forests. The Lyman-alpha forest is an an absorption pattern seen in the spectra of high redshift quasars corresponding to the absorption of the quasar light by the hydrogen clouds along the line of sight. It is a powerful cosmological tool as it probes relatively small scales, of the order of a few Mpc. It is also sensible to small non-linear effects such as the one induced by massive neutrinos.First, we have developed two independent methods to measure the one

Abstract In the structural design of Floating Offshore Wind Turbines (FOWT), fatigue plays a critical role in determining the final design of the system.

These conditions include wind speed and direction, wave height, period and direction and the sea state spectral shape.

Abstract:
Vibration signatures of defective roller bearings on railroad freight cars were analyzed in an effort to develop an algorithm for detecting bearing defects. The effort is part of a project to develop an on-board condition monitoring system for freight trains. The Office of Research and Development of the Federal Railroad Administration (FRA) is sponsoring the project. The measurements were made at the Transportation Technology Center (TTC) in Pueblo, CO on July 26 – 29, 1999 during the Phase III Field Test of the Improved Wayside Freight Car Roller Bearing Inspection Research Program sponsored

Abstract:
This report summarizes the work completed in Year One of the three-year project: PRCI SCC-2-12 Effect of Pressure Fluctuations on Growth Rate of Near-Neutral pH SCC. The investigation in Year One has been primarily focused on the validation of the software being developed for crack growth and remaining life prediction using SCADA Data. A total of 9 pressure spectra, 4 for oil pipelines and 5 for gas pipelines, have been collected and used as inputs for the software. It was found that a pressure spectrum can be quantified using a parameter termed as Spectra Factor to represent the severity of l

Abstract:
The extension of the PRCI on bottom stability (OBS) software's applicability to shallow water is assessed. Version 3 of the software has a limitation on water depth; only depths greater than 6 m (20 ft) are accepted. This limitation is likely related to the increasing inaccuracy of linear wave theory as the wave height to water depth ratio increases, as well as caution about breaking wave limits. The usage of linear wave theory inside the software can be categorized into two different types: � Linear regular waves - these are used in the Level 1 module to determine the motions of the water par

Abstract:
Automated built-up infrastructure classification is a global need for planning. However, individual indices have weaknesses, including spectral confusion with bare ground, and computational requirements for deep learning are intensive. We present a computationally lightweight method to classify built-up infrastructure. We use an ensemble of spectral indices and a novel red-band texture layer with global thresholds determined from 12 diverse sites (two seasonally varied images per site). Multiple spectral indexes were evaluated using Sentinel-2 imagery. Our texture metric uses the red band to s

Abstract:
The PRCI software (version 3.0) which assesses hydrodynamic stability of submarine pipelines was revised. There are three 'levels' of analysis available in this software. The main technical revisions are for: - Level 1 : -The addition of the logarithmic boundary layer formulation. - Level 2: -The addition of the logarithmic boundary layer formulation -The addition of the JONSWAP spectrum -The addition of the Verley and Lund pipe-soil clay model -The resolution of the issue of excessive embedment in current dominated conditions. - Level 3 are: -The addition of the logarithmic boundary layer for

Abstract:
The objective for this two phase project was to validate surface loading criterion for pipelines with shallow burial. This is the report of the first phase of this project which focused on field measurements of the stress in shallow buried pipe while it is being crossed by heavy equipment. During the second phase, this data will be compared with the predictions of the most prevalent models currently used for surface load stress analysis for pipelines with shallow cover. The objective of the two phase study is to have a validated model for surface loading of shallow buried pipe. In the phase I,

Abstract:
The long-term integrity of a dented pipeline segment is a complex function of a variety of parameters, including pipe geometry, indenter shape, dent depth, indenter support, pressure history at and following indentation. In order to estimate the safe remaining operational life of a dented pipeline, all of these factors must be accounted for in the assessment. The current project provides pipeline operators with a methodology for assessing and managing dent fatigue, thus making it possible to prioritize response and remedial action(s) in an informed manner. The methodology allows the users to c
