We conducted an experimental study to determine to what extent computer skill learners can benefit from generating self-explanation with the aid of different computer-based visualization technologies. Selfexplanation was stimulated with dynamic visualization (Screencast), static visualization (Screenshot), or verbal instructions only, and compared to a control group with no self-explanation ins...

A static spherically symmetric metric in Einstein-scalar-tensor gravity theory with a scalar field potential V [φ] is non-singular for all real values of the coordinates. It does not have a black hole event horizon and there is no essential singularity at the origin of coordinates. The weak energy condition ρφ > 0 fails to be satisfied for r . 1.3rS (where rS is the Schwarzschild radius) but th...

High purity Flibe was prepared for corrosion study. Fundamental corrosion experiments in static condition were performed on the structural material for Flibe blanket and Material Research Loop, which is non-isothermal forced convection loop simulating the blanket condition. Corrosion rate for the structural materials in static condition was estimated as small as 0.83-5.4 μm/yr in the high purit...

Azo dye Reactive Red 195 was selected for decolourization and degradation studies by Georgenia sp.CC-NMPT-T3. Optimization of parameters for dye decolourization was studied under static anoxic condition. Under optimized condition decolourization of Reactive Red 195 by Georgenia sp.CC-NMPT-T3 was found to be 95.93 % at 50 mg/L within five hours in static anoxic condition. The optimum pH and temp...

Screening of bovine rumen contents for heat-resistant and micro-aerophilic cellulose-degrading microorganisms was performed on carboxymethyl cellulose (CMC) plates at 37 °C-45 °C, and many isolates were found to produce reducing sugars under a static condition. Of those isolates, R8 and R15, which efficiently produced reducing sugars from CMC at a high temperature, were further examined. Taxono...

In the current study, multiple static-simultaneous visualizations were combined with motion-indicating arrows and were compared either to multiple static-simultaneous visualizations without arrows, which proved to be effective in former studies concerning static visualizations, or to a single static visualization enriched with motion-indicating arrows. Seventy-one students were randomly assigne...

In natural visual situations, unlike most psychophysical experiments, when a new stimulus appears in a portion of the visual field, the surrounding background changes simultaneously. In recordings from macaque V1 we found that a visual stimulus presented simultaneously with a background change evokes a response that is qualitatively different from the response to the same stimulus flashed on a ...

It has been suggested that breaking camouflage is one of the major functions of stereopsis (Julesz, 1971). In this study, we found that stereopsis is less effective in breaking camouflage for moving targets than for static ones. Observers were asked to detect a single dot moving on a straight trajectory amidst identical noise dots in random motion. In the three-dimensional (3D) condition, the n...

PURPOSE To challenge the validity of existing cognitive models of postural control, we recorded eye movements and postural sway during two visual tasks (a control free-viewing task and a difficult searching task), and two postural tasks (one static task in which the platform was maintained stable and a dynamic task in which the platform moved in a sway-referenced manner.) We expected these mode...
