Electroencephalogram (EEG) signals have recently gained attention to classify associated hand movement. This is particularly useful for amputees with prostatic hands or people who are unable to move their hands voluntarily. Among the decoding algorithms used to classify hand movements are support vector machines and multilayer perceptron networks. In this...
As the Civil War dragged on, Abraham Lincoln’s election hopes in 1864 continued to become smaller and smaller. As late as August 23, 1864, Lincoln wrote, “This morning, as for some days past, it seems exceedingly probable that this Administration will not be re-elected. Then it will be my duty...
Using a spectrometer and photomultiplier tube, I measured the electromagnetic radiation transmittance properties of three types of tissue-- ventral skin, cardiac muscle, and liver tissue--in the red-sided garter snake Thamnophis sirtalis parietalis between the wavelengths of 450 and 850 nanometers (nm). Control readings were taken using a 10⁻² neutral density...
When Charles Guiteau killed U.S. President James Garfield, he claimed that God had ordered him to do so. During his trial, Guiteau’s lawyers plead not guilty by reason of insanity, and the question of Guiteau’s innocence or guilt quickly became a question about the very nature of insanity itself. In...
The primary goal was to characterize the adsorption of a recombinant therapeutic protein
in the presence of selected surfactant species at the air-water interface. For this purpose,
dynamic interfacial tensiometry was used to determine the surface tension kinetics
exhibited by protein solutions containing either Tween 80 or the poly[ethylene oxide]-...
Currently available soil moisture sensors have intrinsic limitations that limit their adoption by industry. Depending on the technology, these limitations may include high costs, battery requirements, precice manual installation, high cost, and/or constrictive legislation that regulates their use. A passive soil moisture sensing system based around RFID technology would allay...
This project will act as a resource in secondary schools and workplaces to help facilitate discussion of discrimination and racially motivated crimes against people in the AAPI community. Decades of oppression have led us to the current oppression of Asian Americans, notably showcased during the COVID-19 pandemic. This project highlights...
Lamprey eel harvesting has systematically and periodically occurred along the Siletz River and its tributaries for as many as hundreds, or thousands, or tens of thousands of years that human families and lamprey eel populations have coexisted in the Siletz Valley ecosystem. Historical, cultural, and biological information for the twentieth...
