The Capacitive Touch Children’s Guitar is a fully functional electronic toy demonstrating
an application of Cypress Semiconductor’s CapSense touch sensing technology. It was
developed as a senior design project by myself and two other engineering students. I was
responsible for the guitar’s LED lights, main microcontroller and sound storage and...
As screen resolution and video decoding capability have increased, high-definition (HD) video in resolutions as high as 1920 x 1080 is rapidly becoming the standard. Ad-hoc streaming of HD video over 802.11 wireless networks, e.g., streaming from a mobile device to a television, is convenient for users, but is hampered...
In order to properly utilize organic amendments as nitrogen sources, reliable methods
to estimate plant-available nitrogen (PAN) are needed. The objectives of this study
were to (1) evaluate the use of crop and soil responses in fertilizer N equivalence
(FNE) calculations, (2) examine the relationships between the C/N ratio, total...
Nearly all birds communicate through sound, and there has been much study of avian populations and communities using song and other vocalizations. Owls are no exception as they defend territories, advertise for mates, and defend against threats using various vocalizations. However, due to their generally nocturnal habits, some owl species...
Relative to other systems in the PNW, the rain-dominated, coastal watersheds of western Oregon have shallow aquifers. Given the seasonality of streamflow and storage limitations in coastal, rain-dominated watersheds, changes in the temporal patterns of precipitation have the potential to magnify the risk of extreme streamflow conditions during both high-...
The post-election violence in the aftermath of Iran’s 2009 presidential
election was viewed through the lens of new, social media. New media
publishers created and supported a movement, and in the process they wove
a national struggle into the global media landscape. This exploration places
Twitter in the context of...
The Cackling goose (Branta hutchinsii minima) population has increased from a low of 20,000 in 1984 to the current population of 220,000-300,000 (Stehn 2012, Sanders 2013). As the Cackling goose population began to recover in the late 1990s, the majority of the population relocated from wintering in California to the...
OSU Extension provides important educational services to members of the agricultural community. Programming options can be guided by needs assessment surveys, which are used to determine gaps in knowledge and understanding for communities. The objective of this study was to develop and execute a survey to gather information on: 1)...
Fungi are capable of growth on a wide variety of carbon sources, both living and dead. They can produce an arsenal of enzymes and transporters for harvesting sugars, polysaccharides, amino acids, lipids and micronutrients from their environments [1]. Within the nucleus of a cell, transcription factors (TF) control whether genes...
Within the U.S. there is a growing interest in the case of female adolescents being coerced into the sex industry (Bernstein, 2010; Estes & Weiner, 2001; Soderlund, 2010; Williams and Frederick, 2009). This interest, which emerged due to U.S. involvement in the international trafficking phenomena and grassroots organizing, has resulted...
