Three experiments investigated whether the human visual system can make independent estimations of 3-dimensional shape dimensions, as suggested by structural description models of human object recognition. Experiment 1 used a noise masking paradigm to investigate whether primary-axis curvature and aspect ratio are estimated independently. The results showed clear evidence that these 3-dimension...

Bose-Einstein condensates of sodium atoms have been prepared in optical and magnetic traps in which the energy-level spacing in one or two dimensions exceeds the interaction energy between atoms, realizing condensates of lower dimensionality. The crossover into two-dimensional and one-dimensional condensates was observed by a change in aspect ratio and by the release energy converging to a nonz...

The perceived angular velocity of an ellipse undergoing a constant rate of rotation will vary as its aspect ratio is changed. Specifically, a "fat" ellipse with a low aspect ratio will in general be perceived to rotate more slowly than a "thin" ellipse with a higher aspect ratio. Here we investigate this illusory underestimation of angular velocity in the domain where ellipses appear to be rota...

Security breaches seldom occur because of faulty security mechanisms. Often times, security mechanisms are incorrectly incorporated in an application which allows them to be bypassed resulting in a security breach. Methodologies are needed for incorporating security mechanisms in an application and assessing whether the resulting system is indeed secure. We propose one such methodology for desi...

We propose three-terminal core-shell (CS) silicon vertical nanowire tunneling field-effect transistors (TFETs), which can be fabricated by conventional CMOS technology. CS TFETs show lower subthreshold swing (SS) and higher on-state current than conventional TFETs through their high surface-to-volume ratio, which increases carrier-tunneling region with no additional device area. The on-state cu...

We consider a convection process in thin loops of different geometries. At Ra=Ra(')(cr) a first transition leading to the generation of corner vortices is observed. At higher Ra (Ra>Ra(cr)) a coherent large-scale flow, which persists for a very long time, sets up. The mean velocity nu mass flux m, and the Nusselt number Nu in this flow scale with Ra as nu proportional to m proportional to Ra0.4...

Discrimination was measured for height, area, and aspect ratio of ovals and rectangles. Random jittering of the orthogonal property (width, aspect ratio, and area) was used to control the observers' criterion. Weber fractions for aspect ratio were consistently lower than those for area, and about the same as those for height. Performance with ovals and rectangles did not differ significantly. T...

For percolation on (RL)xL two-dimensional rectangular domains with a width L and aspect ratio R, we propose that the existence probability of the percolating cluster E(p)(L,epsilon,R) as a function of L, R, and deviation from the critical point epsilon can be expressed as F(epsilonL(y(t))R(a)), where y(t) identical with1/nu is the thermal scaling power, a is a new exponent, and F is a scaling f...
