    Evaluation of GEOSAT data and application to variability of the northeast Pacific Ocean
    (Monterey California. Naval Postgraduate School, 1988) Campbell, Jeffrey William; CIVINS (Civilian Institutions); Woods Hole Oceanographic Institution; Massachusetts Institute of Technology
    Part of the N.E. Pacific was studied to evaluate and use altimetric data from the Navy Geodetic Satellite GEOSAT. The zero-order accuracy of the major GEOSAT geophysical data record (GDR) channels was verified, and occasional gaps in the altimeter coverage were noted. GEOSAT's 17-day repeat orbit allowed use of collinear-track processing to create profiles of the difference between the sea surface height along a given satellite repeat, and the mean sea surface height along that repeat's groundtrack. Detrending of sea surface bias and tilt on each repeat reduced orbit and other long wavelength errors in the difference profiles. Corrections provided on the GEOSAT GDR were examined for their effects on the difference profiles of three test arcs. It was found that only the ocean tide, electromagnetic bias, and inverted barometer corrections varied enough over the arc lengths (approx. 4400 km) to have any noticeable effect on the difference profiles. Only the ocean tide correction was accurate enough to warrant using it to adjust the sea surface heights. Recommended processing of GEOSAT data for the area included making the ocean tide correction, three-point block averaging successive sea surface heights, and forming the mean height profiles from 18 repeat cycles (to reduce aliasing of the M2 tidal component), A set of difference profiles for one GEOSAT arc indicated that a reasonable estimate of GEOSAT's system precision was approx. 4.5 cm (RMS). The mid wavelength range (100-500 km) of these profiles was found to be the only range in which oceanic mesoscale features could be separated from altimeter errors

    A Global Force for Good? Human Rights and the U.S. Military in International Disaster Relief Operations
    (Monterey California. Naval Postgraduate School, 2019-05) Koningisor, Jessica; CIVINS (Civilian Institutions); University of California, Berkeley
    This paper examines whether U.S. military support to international natural disaster relief properly accounts for the human rights of the disaster affected populations. The analysis begins with a comprehensive overview of the international legal framework of disaster response and the development of a codified human rights based approach to disaster relief operations. It then specifically assess how that international framework provides human rights guidance for responding military actors. The remainder of the paper examines how the U.S. military accounts for human rights of the affected population in the law and doctrine governing U.S. military disaster relief operations. The analysis concludes with a brief examination of three examples of mission execution assessed against the legal and doctrinal guidance, to determine if U.S. military action considers a human rights based approach.

    A case study on pile relaxation in dilative silts
    (Monterey California. Naval Postgraduate School, 2011) Richardson, Brent D.; CIVINS (Civilian Institutions); Ocean Engineering
    In the mid-1980s the Jamestown Verrazzano Bridge was built in Rhode Island spanning the west passage of Narragansett Bay. The bridge was to be founded primarily on pre-stressed concrete piles acting as friction piles. A test pile program was conducted at the beginning of construction and the measured capacity of the piles was significantly lower than predicted values. This led to significant delays in construction, cost overruns, and ultimately led to a change in the design of the foundations. The overall objective of this thesis is to evaluate the results of the test pile program and attempt to understand why the measured capacities were so much lower than design values.

    Smart applications for Facilities
    (Monterey California. Naval Postgraduate School, 2019-08) Hemmings, Okang A.; CIVINS (Civilian Institutions)
    This research shares the investigation of various types of smart applications for facilities. This includes discussions regarding the primary stakeholders, technical aspects, and the financial and environmental implications with respect to their use. The research will deliberately address some topics in general terms to establish a background, while targeting other areas in more details to highlight their applications.

    Lithium Car Battery Industry: "Is this Industry Really Environmentally Friendly?"
    (Monterey California. Naval Postgraduate School, 2020-02-04) Bencs, Shannon K.; CIVINS (Civilian Institutions)
    This document will discuss and expose the hazards of the lithium-ion battery industry and the possible long-term affects the industry has on the environment. There will also be a comparison made on the petroleum industry and lithium-ion battery industry to see which one is causing the most environmental damage.

    An Analysis of 4D Modeling for Use by the Naval Facilities Engineering Command
    (Monterey California. Naval Postgraduate School, 2004) Jors, Patrick C.; CIVINS (Civilian Institutions); Civil Engineering
    The purpose of this paper is to explain recent research on the costs and benefits of 4D CAD technology to determine if it can benefit the U.S. Navy in management of its construction projects. The report will begin with a brief history of project management and the development of 4D computer based models. Sections 3 and 4 will discuss advantages and disadvantages of using 4D programs. An overview of the Navy's organization, mission, and construction management team will be presented for understanding the 4D CAD implementation plan discussed in section 6. The report will conclude with a financial analysis to determine what size and type of Navy project 4D CAD would be most economically useful for.

    Uncertainty and sensitivity analysis of a fire-induced accident scenario involving binary variables and mechanistic codes
    (Monterey California. Naval Postgraduate School, 2010-09) Minton, Mark A.; CIVINS (Civilian Institutions)
    In response to the transition by the United States Nuclear Regulatory Commission (NRC) to a risk-informed, performance-based fire protection rulemaking standard, Fire Probabilistic Risk Assessment (PRA) methods have been improved, particularly in the areas of advanced fire modeling and computational methods. In order to gain a more meaningful insight into the methods currently in practice, it was decided that a scenario incorporating the various elements of uncertainty specific to a fire PRA would be analyzed. Fire induced Main Control Room (MCR) abandonment scenarios are a significant contributor to the total Core Damage Frequency (CDF) estimate of many operating nuclear power plants. This report details the simultaneous application of state-of-the-art model and parameter uncertainty techniques to develop a defensible distribution of the probability of a forced MCR abandonment caused by a fire within a MCR benchboard. This report details the simultaneous application of state-of-the-art model and parameter uncertainty techniques to develop a defensible distribution of the probability of a forced MCR abandonment caused by a fire within a MCR.

    A guide to resolving disputes over defective specifications
    (Monterey California. Naval Postgraduate School, 1992) Wirsching, Steven M.; Thomas, M. Randolph; CIVINS (Civilian Institutions); Civil Engineering
    This thesis investigated the legal criteria involved in resolving defective specification disputes. Appellate case law was researched to discover the rules used by the court systems to decide cases involving defective specifications. These rules were organized in flowchart form to provide a guide for construction contract administrators. Separate flow charts were prepared for method and performance specifications, and the differences between the two types of specifications were discussed. Appellate court cases were used to illustrate how the courts have interpreted and applied the legal rules in construction contract disputes. The differences between defective specifications and differing site conditions were also investigated. A discussion of the significant differences was provided to assist construction professionals in distinguishing the two dispute situations.
