To generate a series of frames with a small inter-frame change in the speckle pattern, we repeatedly add a small randomly distributed phase to the phases in the L' by L' square in the generating matrix and recalculate the speckle pattern.
"Run" corresponds to a phase of directional migration, while "tumble" is a reorientation phase characterized by collapse of protrusions and by a series of small, randomly oriented movements, with no net migration.
For some tests, vision was corrupted to produce "blotched" images to simulate visual impairment: images were covered by a small random number of randomly placed black circles occluding approximately (20%) of the pixels.
An array in which the value of α is not constant across the central group of oscillators, but instead varies randomly by a small percentage, displays peaks that are well localized in frequency (Figure 5A).
The measurement was repeated ten times and each time the sample position was shifted randomly by a small amount (~ ± 0.2 mm) in the direction perpendicular to the wave propagation path, such that the final evaluation result will be the averaged contribution from an area of rectangular shape with ~0.4 mm width.
The GeneTrek approach has been proposed as an efficient means to evaluate the general properties of any genome by annotating a small set of randomly selected BACs [ 19, 20].
It is likely that the diagnostic floral traits are controlled by a small number of genes, and the randomly distributed AFLP markers were probably not located within those genes.
A robotic Prius, submitted by a small California team called the Golem Group, veered randomly into a curb on Monday, bursting a tire.
He takes Rosie away to a small town (randomly chosen) near the coast, and has dinner with her.
Each of these sculptures is a greatly enlarged, glossily lacquered, stainless-steel representation of something small: a toy dog made of twisted-together balloons; a chocolate valentine heart wrapped in red foil, standing en pointe; and a silhouette of Piglet from a "Winnie the Pooh" coloring book, randomly colored as if by a small child.
