Failure analysis of pre-notched composite laminated plates under four-point bending conditions

Creator:: Arias Gonzales, Sergio
Abstract:: Ever since composite laminate technology was introduced into the aerospace and automotive industry, there has been a need to fully understand the damage progression experienced by composite laminated plates in the presence of a notch. While numerous research studies have been conducted on this matter when subjected to in-plane loads,...

Ecology of Greenland halibut (Reinhardtius hippoglossoides) during the early life stages in the Eastern Bering Sea and Aleutian Islands

Creator:: Sohn, Dongwha
Abstract:: Greenland halibut (Reinhardtius hippoglossoides) have decreased in the eastern Bering Sea and Aleutian Islands since the 1970s. The reasons behind the poor recruitment are unknown, and important knowledge gaps of the ecology of the early life stages have been identified. The objectives of thesis research were (1) to examine geographic...

New Insights into Mantle Dynamics from Helium Isotopes and Argon Geochronology

Creator:: Konrad, Kevin
Abstract:: Earth’s mantle extends to nearly 3000 km depth, comprises >80 % of Earth’s total volume, and has the largest influence on the primordial and radiogenic heat budget. Despite its importance, the structure and composition of the mantle is still debated. There are three primary models for Earth’s mantle structure that...

Full Text:: ingredients. Novolak is produced with acid catalysis and a deficiency of formaldehyde. It has no reactive

Prompt gamma neutron activation analysis of niobium for characterization of light interstitials

Creator:: Love, Ian J.
Abstract:: High purity niobium metal is used in the construction of superconducting radio frequency (SRF) cavities in superconducting particle accelerators, such as the Large Hadron Collider (LHC) at CERN or the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory. The usual method for characterizing the impurities in this niobium, the...

Secrecy of massive MIMO systems under antenna failure

Creator:: Assiri, Mohammad
Abstract:: As the fifth generation of mobile communication systems (5G) is being deployed, massive multiple-input multiple-output (MIMO) serves as one of its enabling technologies where reliable and ultra low latency communications are achieved while being power and spectrum efficient. This thesis studies the security aspect of massive MIMO system from the...

Electronic Properties of Passive Films on Carbon Steel Rebar in Simulated Concrete Pore Solutions

Creator:: Williamson, Jon W.
Abstract:: In the highly alkaline environment of concrete, carbon steel rebar is protected against corrosion by a passive oxide/oxyhydroxide film. Understanding the characteristics of this passive film, and how it depassivates, is the key for mitigating problems associated with steel corrosion in concrete. Although a large number of electrochemical and analytical...
Resource Type:: Masters Thesis
Full Text:: additional information to improve the mechanistic models for chloride-induced depassivation of carbon steel

Processing of laser interferometric signals for small displacement measurements

Creator:: Peng, Gwo-sheng
Abstract:: Algorithms for analyzing laser interferometry signals were developed and adopted to the computer based processing of small displacement measurements. These methods, matrix operation approach and fixed parameters approach, are based on signal phase calculation and are able to replace complex fringe counting electronic circuits. The matrix operation provides an approach...

Comparison of HEU and LEU neutron spectra in irradiation facilities at the Oregon State TRIGA® reactor

Creator:: Schickler, Robert
Abstract:: In 2008, the Oregon State TRIGA® Reactor (OSTR) was converted from highly-enriched uranium (HEU) fuel lifetime improvement plan (FLIP) fuel to low-enriched uranium (LEU) fuel. This effort was driven and supported by the Department of Energy's (DoE's) Reduced Enrichment for Research and Test Reactors (RERTR) program. The basis behind the...

Productive Interactions in a Complex Engineering Project: Influence of Team Members, Engineering Practice, and Emergence of Roles

Creator:: Chindanon, Kritsa
Abstract:: Engineering capstone projects are intended as a bridge from school to professional practice in which students work in teams to use learned knowledge and skills to complete real-world engineering projects. However, while the majority of time in many undergraduate programs is devoted to development of technical knowledge and skills, there...
