Ultrasonic Attenuation In As-Deposited Inconel 182 Weld Metal and Recommended Techniques for Discontinuity Evaluation.
This thesis reports on a study of the problems associated with the ultrasonic evaluation of full penetration welds in pressure retaining bi-metallic and tri-metallic joints involving as-deposited austenitic weld material. The weld joint design was one simulating a component on a nuclear reactor …

A Fiber-Reinforced Plastic Joint for Filament-Wound Pipes: Analysis and Design
… failure mechanisms, failure from the standpoint of strength and leakage. The strength design procedure is derived from first principles taking into account the orthotropy of the fiber reinforced plastic material. The leakage analysis follows the guidelines of the American Society of Mechanical …

A Study of the Bulk Electrical Resistivity Characteristics of Fly Ash from Lignite and Other Western Coals
… using electrostatic precipitation. Efficiency of precipitation depends to a large extent on the bulk electrical resistivity of the fly ash which in turn depends on conditions such as ash temperature, moisture content of the gas, and ash composition. Bulk electrical resistivity is the total …

Critical Erosion/Corrosion Piping Wall Thicknesses Under Static and Fatigue Stress Conditions According to ASME Guidelines
The purpose of this project was to show the updated procedures and to make additions to the computer program called Tmin designed by E. I. DuPont De Nemours and Company. This program is used as a screening tool for determining the largest of the minimum pipe-wall thicknesses in a piping system. …

Practical Analysis Tools for Structures Subjected to Flow-Induced and Non-Stationary Random Loads
… upon existing methods to predict response of sensors due to flow-induced vibrations in a pipe flow. The aim was to develop a tool which would enable an engineer to quickly evaluate the suitability of a particular design for a certain pipe flow application, without sacrificing fidelity. The …

On the use of machine learning with design optimization data for system topology design
… topology design, leveraging design data instead of designer intuition derived from experience or established gradient-based topology optimization methods. As a preliminary study for this dissertation, the research literature for a relevant segment of the engineering design research community was …

Microstructural evolution and mechanical behavior in nickel based alloys for very high temperature reactor
… National Laboratory (INL). A major limitation of this system is the development and qualification of high-temperature materials for structural applications. Such materials must possess good high-temperature resistance. Among candidate materials, Alloy 617 and Alloy 230 are considered the most …

Julius Otto Kaiser and his method of systematic indexing: an early indexing system in its historical context
… and indexer who developed, in last years of the 19th, and the first years of the 20th, centuries, an innovative method of subject indexing known as systematic indexing (SI). Although Kaiser has long been recognized as a pioneer in the field of knowledge organization (KO) and SI has been …
