Current robots are no match for biological organisms when adapting to real-world, dynamic environments. Collective control strategies, such as those used by synergistic biological systems composed of large numbers of identical parts like the human nervous system, provide a novel and alternative approach for the design of fault-tolerant, adaptable robotic...
Modern walking robots have shown that dynamic gaits can be achieved without ankle motors. It seems logical that the additional control authority that they provide can be used to improve the stability of the walking gait against foot placement errors caused by low level control. This thesis develops and compares...
Deburring of machined parts is a crucial task in the aerospace and automotive industry. This process is still performed manually to a large extent due to the unpredictability of burr formation as well as the complex interactions between the human arm and the workpiece. Poor ergonomics, repetitive stress and strain...
Remote-access computer file serials, often referred to simply as electronic serials, possess characteristics that challenge our definition of the term “serial” and our ability to catalog them according to the established cataloging code. These challenges are reflected in the library science literature, where cataloging and indexing issues have generated thoughtful...
Recently, Duke and Jenkins have studied a certain family of modular forms fk,m, that form a natural basis of the space of weakly holomorphic modular forms of weight k on SL2(Z). In particular, they prove that for all but at most [k/12] + 1 values of m, the zeros of...
Let us travel the 65-mile length of the Columbia River Gorge for a closer look at the rock formations and geology of the area. We will supplement our observations with information from the literature on the geology of the Gorge and try to put together a picture of how the...

Seismically active areas exist within Oregon. The seismic history of Oregon is too short to be used as an accurate predictor of earthquake size, number, and distribution. Continual monitoring of earthquakes by seismograph stations during the next several decades should provide a more accurate estimate of the seismicity of Oregon....
