by Alan Scott Boydstun, Ph.D. Washington State University May 2009 Chair: Robert Patterson A debate exists regarding the relative processing level of cyclopean-defined motion in the visual system. Some authors have attributed the processing of cyclopean-defined motion to stages in the visual system that enact similar algorithms of motion computation to luminance-defined motion; whereas, other a...

Since the advent of electroacoustic music, and even earlier, musicianshave shown an interest in using the spatial distribution of sound as a significant consideration in composition. Whilethere have been many attempts to realize the musical potential suggested by this possibility, certain problems have intervened. Significantly, these have been primarily in the technological rather than the mus...

In the DELIS project 1 , a set of parallel monolingual lexicon fragments have been designed. They are parallel in two ways: (1) they cover the same fragment (the most general verbs of sensory perception and of speech act), and (2) they are based on the same theoretical approaches and on comparable classiications and descriptive devices. It is claimed in this paper that such parallel fragments, ...

Directional selectivity, in which neurons respond strongly to an object moving in a given direction but weakly or not at all to the same object moving in the opposite direction, is a crucial computation that is thought to provide a neural correlate of motion perception. However, directional selectivity has been traditionally quantified by using the full spike train, which does not take into acc...

In design and analysis, standard references assume the pedestrian flow as unidirectional. In reality however, pedestrian flow is usually bi-directional. The main question pursued in this paper is that whether the main characteristics of pedestrian flow the same under uni- and bi-directional conditions. In order to achieve this goal, effect of bi-directional stream is inv...

The dogleg severity is one of the most important parameters in directional drilling. Improvement of these indicators actually means choosing the best conditions for the directional drilling in order to reach the target point. Selection of high levels of the dogleg severity actually means minimizing well trajectory, but on the other hand, increases fatigue in drill string, increases torque and d...

Previous studies on categorical perception of lexical tones showed that perception of Cantonese lexical level tones depends on pitch level of contexts and the contextual effect is specific to speech. Moreover, a pair of stimuli with a right context is easier to discriminate than that with a left context. Although this directional asymmetric perception was observed from both native and nonnative...
