Anthropogenic releases of trace gases into the
atmosphere are causing a decrease in stratospheric ozone
concentrations and a subsequent increase in solar
ultraviolet-B (UV-B)(280-320 nm) radiation reaching the
earth's surface. The objective of this study was to
determine the acute effects of enhanced UV-B radiation on
the primary production of...
Each year, whether it be under voluntary or unvoluntary circumstances, countless professional athletes retire from their sport. Even by the average retirement age of 30, many are still underprepared to face the challenges that accompany the transition. Along with the changes in schedule, identity, and social group, numerous professional athletes...
The present research sought to investigate individual differences in the way individuals process intuitive risk judgments. The present investigation is centered on Fuzzy Trace Theory (Brainerd & Reyna, 1991), a developmental dual process theory of cognition which posits two ways in which individuals process information, gist and verbatim processing. 228...
Dynamic DC offset is one of the biggest problems preventing the implementation of single chip receivers. This thesis presents a 2.4GHz downconversion mixer designed to work with adaptive DC offset cancellation for a fully integrated direct conversion receiver. Offset can be removed by dynamically changing the PFET load bias in...
One of the greatest technological breakthroughs of humanity was the ability to
construct a device and eventually a system which would provide a more efficient, safe,
clean, convenient and relatively inexpensive form of illumination than ever used previously
electric light. The introduction of this new technology into Oregon
communities in...
Global increases in ultraviolet-B radiation (UVBR:290-
320 nm) resulting from decreases in stratospheric ozone
concentration have the potential to alter marine primary
production and affect global climate and marine trophic
dynamics. Effects of UVBR on phytoplankton carbon fixation
were determined from open ocean exposure studies conducted
off the coast of...
An understanding of creativity’s emergence is critical as our society faces new challenges. Despite a growing body of research emphasizing nature’s influence on the creative process, we now spend record amounts of time indoors, disconnected from nature. Biophilic design has been afforded as a panacea, with research supporting the incorporation...
A new, fully automated summarization algorithm of MPEG compressed videos is designed to address the challenge of content based video retrieval. This algorithm segments the MPEG stream motion vector magnitudes using a seed growing region technique. Following the spatial segmentation of each frame, an intra-frame class-merging operation is performed. The...
