A method for improving performance/watt of an embedded single-instruction multiple-data (SIMD) architecture using application-guided a priori scheduling of hardware resources is presented. A multi-core architectural simulator is adopted that accurately estimates power, performance, and utilization of various processor components (logic, interconnect and memory). A greedy search is then performed on...
This thesis discusses the design and evaluation of an instrument
that can detect known signals in noise. This detector uses
two integrators to sense a difference in the received signal between
half-cycles of the known signal.
The detector is useful for sensing signals in the approximate
frequency range of 100...
The marine psychrophilic bacterium Vibrio marinus MP-4
possessed a maximum temperature and hydrostatic pressure of
20 C and 425 atm for growth. The effects of temperatures of 21 and
25 C and hydrostatic pressures of 200, 400, 500, and 1,000 atm on
protein, RNA and DNA synthesis by V. marinus...
Vibrio marinus MP-1 (ATCC 15381) deaminated nine of seventeen
amino acids tested with L-glutamine being deaminated to the greatest
and L-serine to the second greatest extent in one hour. The optimum
pH for the L-serine deamination was 8.4.
The response of washed cells to temperature on the deamination
of L-serine...
This thesis presents a method for determining the
kinematic geometry of arthropod legs. A kinematic
description makes possible the analysis of arthropod leg
motion, as a prelude to investigating how various arthropod
species are able to negotiate diverse terrains. Such
knowledge will aid in design of legged vehicles.
The focus...
Studying human’s ability to estimate temporal durations could lead to a greater
understanding of our cognitive abilities as well as the processes that underlie temporal
estimation. It has been shown through previous research that time and number may be
interconnected cognitively and that the magnitude of one may alter the...
Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...
A wearable, multi-modal sensor is presented that can non-invasively monitor a patient’s activity level and heart function concurrently for more than a week. The 4in² sensor incorporates both a non-contact heartrate sensor and a 5-axis inertial measurement unit (IMU), allowing simultaneous heart, respiration, and movement monitoring without requiring physical contact...
Field deployments, flume experiments, and a 2D wave model have been used to identify the characteristics of Clark-type oxygen microelectrodes and measurement parameters that could possibly bias eddy correlation (EC) flux measurements made under waves. Eddy correlation is a technique adapted from atmospheric sciences that couples concurrent and co-located velocity...
This study explores Oregonians’ attitudes about and perceptions of public education. Specifically, perceptions about education quality were analyzed, looking at the perceived quality of education today and how it has changed over the last 5 years. Questions posed to respondents about education funding, explored views on additional state funding needed...
