Advanced Anchoring and Mooring Study

Creator:: Sound & Sea Technology Engineering Solutions
Abstract:: This report establishes an industry knowledge base for existing anchoring and mooring techniques as applied to wave energy conversion (WEC) devices in and around Oregon. This report on anchoring and mooring techniques is derived from the cumulative experiences of engineers and scientists with many years of experience analyzing, designing and...

OP-AMP free SC biquad LPF and delta-sigma ADC

Creator:: Yoo, Kiseok
Abstract:: The objective of this work is to explore the feasibility of replacing conventional op-amps with inverters in switched-capacitor (SC) circuits. In order to verify the idea, a low-pass filter (LPF) and a second-order delta-sigma (∆Σ) analog-todigital converter (ADC) are designed in the 0.5-m CMOS technology. The low-pass filter structure is...

Vertical Zoning in Marine Protected Areas: Ecological Considerations for Balancing Pelagic Fishing with Conservation of Benthic Communities

Creator:: Grober-Dunsmore, Rikki, Wooninck, Lisa, Field, John, Ainsworth, Cameron, Beets, Jim, Berkeley, Steve, Bohnsack, Jim, Boulon, Rafe, Brodeur, Richard, Brodziak, John, Crowder, Larry, Gleason, Danny, Hixon, Mark, Kaufman, Les, Lindberg, Bill, Miller, Marc, Morgan, Lance, and Wahle, Charles
Abstract:: Marine protected areas (MPAs), ideally, manage human uses that threaten ecosystems, or components of ecosystems. During several recent MPA designation processes, concerns have arisen over the scientific justification for no-take MPAs, particularly those that restrict recreational fishing for pelagic species. An important question is: under what conditions might recreational pelagic...

Teacher argumentation in the secondary science classroom : images of two modes of scientific inquiry

Creator:: Gray, Ron E.
Abstract:: The purpose of this exploratory study was to examine scientific arguments constructed by secondary science teachers during instruction. The analysis focused on how arguments constructed by teachers differed based on the mode of inquiry underlying the topic. Specifically, how did the structure and content of arguments differ between experimentally and...

Substrate noise coupling analysis in 0.18um silicon germanium (SiGe) and silicon on insulator (SOI) processes

Creator:: Pham, Hui En
Abstract:: Analysis of substrate noise coupling has been performed for a 0.18¹m lightly doped silicon germanium BiCMOS process. Techniques to minimize noise coupling in the chip and board design are presented, as well as methods for accurate modeling for substrate noise coupling simulations. Measurements from a test chip were taken to...

Sub-threshold effects on the perceived intensity of recognizable odorants : the roles of functional groups and carbon chain lengths

Creator:: Lopetcharat, Kannapon
Abstract:: Sub-threshold effects were studied in binary and tertiary mixtures comprising a panel-recognition-concentration odorant and sub-threshold odorant(s). Sub-threshold condition was maintained by controlling the sub-threshold concentration as percentages of subjects' individual detection threshold. The perceived intensities (overall intensity and several descriptors) of recognizable odorants were rated using magnitude estimation. Sub-threshold suppression...

Protein adsorption on chitosan-polyanion complexes : application to aqueous food processing wastes

Creator:: Savant, Vivek
Abstract:: Chitosan has been proposed as a "natural" coagulating agent to solve wastewater problems. The main hindrance in this commercial chitosan application has been its low cost effectiveness. The hypothesis in our research is that chitosan complexes with natural polyanions is more effective than chitosan alone, particularly in recovering low concentration...

Immobilization of hen egg white lysozyme by the sole histidine residue to polystyrene beads through peptide spacers

Creator:: Wu, Yawen
Abstract:: Lysozyme is a natural antimicrobial agent that is effective against many food spoilage and pathogenic microorganisms by disintegrating their cell walls. Immobilization of lysozyme has attractive applications for use in the food industry: (1) The enzyme could be readily separated from treated foods and beverages and re-used while the foods...

A practical implementation of self-efficacy theory to improve the engineering curriculum

Creator:: Plisch, Marjorie
Abstract:: What are the most effective ways to improve the engineering curriculum? Improvements should result in increased student retention, undergraduates who are more industry-ready and graduates who are better prepared to be leaders. Current research suggests that the best predictor of persistence is a person’s self-efficacy. The focus of this thesis...
