BACKGROUND: Manual wheelchair users are at a high risk of repetitive strain injuries, carpal tunnel syndrome, and rotator cuff tears due to propelling their for mobility. Rolling resistance (RR) is one the key forces that leads increased propulsion injuries. OBJECTIVE: To better understand factors contributing RR, we iteratively designed, developed, validated drum-based testing machine test met...

Title of dissertation: MECHANISMS FOR AXIAL BAND FORMATION IN A ROTATING DRUM OF GRANULAR MATERIAL Michael K. Newey, Doctor of Philosophy, 2006 Dissertation directed by: Professor Wolfgang Losert Department of Physics We study granular particles, like sand or glass beads, that are mixed in a partially filled, horizontal, cylindrical drum. When the drum is rotated, it is observed that there is a...

A reverse driving control method for hydrostatic double-drum vibratory rollers is devised in this paper. Based on the analysis of dynamic characteristics of stopping process, the relationship equation between engine speed and pump displacement is established. To restrict the peak value of engine overspeed within the allowable region, an offline parameter determination approach complied with the...

The water level of boiler drum is one of the crucial control parameters for any process industry which reflects the control of mainly boiler load and feed water indirectly. If the level exceeds the limits, boiler water carryover into the superheater or the turbine may cause damage resulting in extensive maintenance costs. If the level is low, overheating of the water wall tubes may cause tube r...

Stable carbon (δ13C) and oxygen (δ18O) isotope ratios in otoliths were used to assess the degree of connectivity between early life and adult habitats of red drum Sciaenops ocellatus in the northern Gulf of Mexico. Young-of-the-year (YOY) red drum were sampled over a 3 yr period from major estuaries along the Texas coast, and otolith δ13C and δ18O were quantified to determine whether chemical t...

In this paper we describe the most important concepts of the belief revision system DRUM and show its use in model-based diagnosis. DRUM works directly on (logical) models and uses neither connicts nor justi-cations. The system description plus observations are seen as integrity constraints, while the inferred facts as well as assumptions about behavioral modes are revised whenever they connict...

Sounds of hammering or clapping can evoke simulation of the arm movements that have been previously associated with those sounds. This audio-motor transformation also occurs at the sequential level and plays a role in speech and music processing. The present study aimed to demonstrate how the activation pattern of the sensorimotor network was modulated by the sequential nature of the auditory i...

Previous observation of spontaneous speech has shown consistent use of pitch accent by speakers to mark the contrastive status of words. To investigate how listeners process accentual prominence marking a contrast, eyemovements were monitored while participants listened to spoken directions and searched for ornaments to decorate holiday trees. Eye movement latencies to the target ornament cells...
