Characterization Of Individual Submicron Perfluorocarbon Gas Bubbles By Ultrasonic Backscatter, E. Carr Everbach, D. B. Khismatullin, J. T. Flaherty, R. A. Roy Jul 2005

Characterization Of Individual Submicron Perfluorocarbon Gas Bubbles By Ultrasonic Backscatter, E. Carr Everbach, D. B. Khismatullin, J. T. Flaherty, R. A. Roy

Engineering Faculty Works

Measurements were undertaken to determine the unknown microbubble-size distribution of a dodecafluoropentane (DDFP) emulsion consisting of in surfactant-stabilized water. The acoustic backscatter of 2-microsecond-duration tonebursts of 30-MHz focused ultrasound was measured from the emulsion as it moved in a coaxial flow. Calibration for the system was accomplished using 3-μm-radius polystyrene spheres, using a linear scattering model and literature values for polystyrene. Applying viscous linear scattering theory to the backscatter data from individual DDFP bubbles allowed inversion of the radius–backscatter relation. A mean microbubble radius of 130 nm was inferred for the DDFP population. © 2005 Acoustical Society of America.

Pulse Regulation Control Technique For Flyback Converter, Mehdi Ferdowsi, Ali Emadi, Mark Telefus, Curtis Davis Jul 2005

Pulse Regulation Control Technique For Flyback Converter, Mehdi Ferdowsi, Ali Emadi, Mark Telefus, Curtis Davis

Electrical and Computer Engineering Faculty Research & Creative Works

Pulse regulation, a fixed frequency control technique, is introduced and applied to flyback converter operating in discontinuous conduction mode (DCM). The control parameters are designed in a way that the converter operates as close as possible to the critical conduction mode. In contrast to the conventional pulsewidth modulation control scheme, the principal idea of pulse regulation is to achieve output voltage regulation using high and low-power pulses. Pulse regulation is simple, cost effective, and enjoys a fast dynamic response. The proposed technique is applicable to any converter operating in DCM. However, this work mainly focuses on flyback topology. In this …

Mobility-Pattern Based Localization Update Algorithm For Mobile Wireless Sensor Networks, Mohammad Yacoub Al-Laho

Electrical & Computer Engineering Theses & Dissertations

In mobile wireless sensor networks, sensors move in the monitored area at any direction and speed. Unlike many other networking hosts, sensor nodes do not have global addresses. They are often identified by using a location-based addressing scheme. Therefore, it is important to have the knowledge of the sensor location indicating where the data came from. In this thesis, three localization update algorithms were designed, Specifically, a sensor movement is divided into three states: Pause, Linear, and Random. Each state adopts different localization update algorithm. Since complex movement involves different mobility patterns, a state transition model is developed to …

The Phosphoglycolate Phosphatase Gene And The Mutation In The Phosphoglycolate Phosphatase-Deficient Mutant (Pgp1-1) Of Chlamydomonas Reinhardtii, Kensaku Suzuki, Hidenobu Uchida, Tarlan G. Mamedov Jul 2005

The Phosphoglycolate Phosphatase Gene And The Mutation In The Phosphoglycolate Phosphatase-Deficient Mutant (Pgp1-1) Of Chlamydomonas Reinhardtii, Kensaku Suzuki, Hidenobu Uchida, Tarlan G. Mamedov

Papers in Biochemical Engineering

The sequences of the phosphoglycolate phosphatase (PGPase) gene Pgp1 and the 5′-upstream region from Chlamydomonas reinhardtii wildtype 2137 and the pgp1-1 mutant N142 that lacks the activity of PGPase (PGP1) were determined. The comparison revealed the alteration of a G to A at position 98 relative to the start codon. This destroyed the “GT” splice donor site at the beginning of the first intron of this gene, resulting in an extension of the first exon to 49 translatable codons followed by a stop codon, containing the codons corresponding to whole transit peptide for the chloroplast stroma and the first four …

Enhancing The Oregon Crash Reporting Process: A Feasibility Study, Christopher M. Monsere, Erin E. Wilson, Amber Springberg Jul 2005

Enhancing The Oregon Crash Reporting Process: A Feasibility Study, Christopher M. Monsere, Erin E. Wilson, Amber Springberg

Civil and Environmental Engineering Faculty Publications and Presentations

In most states, police officers and trained investigators complete crash reports for nearly all reportable crashes that occur on public roads. Many states have made significant improvements in the quality and timeliness of their crash data systems by implementing, in addition to other improvements, electronic filing of these reports by police officers. Oregon relies on citizen reports for a majority of their crash data and paper forms must be submitted to the responsible state agency and are then manually coded into the crash data system. Police reports are also paper based. This process limits the improvements that can be made …

Improved Network Analysis Of Coupled Antenna Diversity Performance, Michael A. Jensen, Matthew L. Morris Jul 2005

Improved Network Analysis Of Coupled Antenna Diversity Performance, Michael A. Jensen, Matthew L. Morris

Faculty Publications

This paper presents a new framework for the analysis of mutually coupled diversity antennas based on network theory. The network model incorporates the matching network between the antennas and front-end amplifiers and uses a realistic model for the amplifier noise. The resulting analysis includes the impact of the coupled-antenna radiation patterns and impedance characteristics in determining the branch signal-to-noise ratios (SNRs). Application of the formulation to coupled dipole antennas characterized using full-wave electromagnetic analysis illustrates that a matching network providing a minimum amplifier noise figure achieves significantly better diversity performance than one providing maximum power transfer.

Approximate Strategic Reasoning Through Hierarchical Reduction Of Large Symmetric Games, Michael P. Wellman, Daniel M. Reeves, Kevin M. Lochner, Shih-Fen Cheng, Rahul Suri Jul 2005

Approximate Strategic Reasoning Through Hierarchical Reduction Of Large Symmetric Games, Michael P. Wellman, Daniel M. Reeves, Kevin M. Lochner, Shih-Fen Cheng, Rahul Suri

Research Collection School Of Computing and Information Systems

To deal with exponential growth in the size of a game with the number of agents, we propose an approximation based on a hierarchy of reduced games. The reduced game achieves savings by restricting the number of agents playing any strategy to fixed multiples. We validate the idea through experiments on randomly generated local-effect games. An extended application to strategic reasoning about a complex trading scenario motivates the approach, and demonstrates methods for game-theoretic reasoning over incompletely-specified games at multiple levels of granularity.
