The Maintenance and Reliability Center (MRC) at The University of Tennessee, performs research and applies cutting-edge technology to help its member companies reduce losses caused by equipment downtime. The first MRC research project dealt with the precision alignment of rotating machinery. Controlled experiments were performed at The University of Tennessee and at the Oak Ridge Center for Ele...
Color mismatches that result from geometric misalignment are studied. Differences in color can result when adjacent parts of an object are coated with the same paint but are not aligned to create a continuous geometric surface. The color difference that results due to shading can be accentuated by the use of metallic and pearlescent paints with goniochromatic properties. A metric is developed f...
The alignment of three mirror anastigmatic (TMA) telescopes has been studied since their invention in the 60s. Recently, Thompson et al. reported that other than the conventional uniform coma over the field caused by misalignment, TMA telescopes display only one other misalignment induced aberration, field-asymmetric, field-linear astigmatism. Currently, an instrument with three TMAs is under d...
Previous studies have demonstrated that accommodation will respond to sine gratings in which the relative modulations of red, green and blue image components have been altered to simulate the effects of defocus and longitudinal chromatic aberration. The present study aimed to determine the tolerance of the accommodative system to relative phase shifts in those components induced by chromatic mi...
We are studying the undersea wireless power transfer to probes. One of problems is that transmission efficiency decreases due misalignment receiving coil caused by tidal currents. By bending spiral used as coil, magnetic fluxes, which does not interlink transmitting and can link coils magnetically. The increase interlinked fluxes suppresses decrease in case misalignment. using a bent compared w...
This paper inspects the misaligned of shaft by using diagnostic medium such as current and vibration. Misalignments in machines can cause decrease in efficiency and in the long-run it may cause failure because of unnecessary vibration, stress on motor, bearings and short-circuiting in stator and rotor windings. In this study, authors investigate the onset of instability on a shaft mounted on jo...
This study reports a new depth illusion in which a static flat pattern appears stratified stereoscopically when viewed binocularly with an elevated gaze. Three psychophysical experiments measured perceived relative depth and fixational cyclodisparity (a rotation of one eye's view relative to the other eye's view about the line of sight) when flat patterns drawn with solid or dashed curved lines...
A central finding in dialogue research is that interlocutors rapidly converge on referring expressions which become progressively contracted and abstract. However there is currently no consensus on which mechanisms underpin convergence: The interactive alignment model (Pickering and Garrod, 2009) favours alignment processes, the grounding model (Clark, 1996) prioritizes positive feedback, while...
Ocular alignment and saccades were studied in seven patients with trochlear nerve pareses, before and after strabismus surgery. Prior to surgery, a position-dependent vertical ocular misalignment was present, and downward saccades were hypometric in the paretic eye. Strabismus surgery reduced the magnitude and position-dependence of the static misalignment. Saccade conjugacy improved in the pat...
The source of a spatial contribution to the coefficient of variation in Affymetrix GeneChip r © probe cell summaries was determined to be caused by a misalignment of probe cell locations in the hybridisation image. Described, is an algorithm that corrects for misalignment resulting in improved allocation of pixel intensities to probe cells and a substantial reduction in the variance of pixel in...
