Smoke Obscuration Measurements in Reduced-Scale Fire Modelling Based on Froude Number Similarity

Froude number corrections in anthropological studies.

The Froude number has been widely used in anthropology to adjust for size differences when comparing gait parameters or other nonmorphological locomotor variables (such as optimal walking speed or speed at gait transitions) among humans, nonhuman primates, and fossil hominins. However, the dynamic similarity hypothesis, which is the theoretical basis for Froude number corrections, was originall...

Humans, geometric similarity and the Froude number: is ‘‘reasonably close’’ really close enough?

Understanding locomotor energetics is imperative, because energy expended during locomotion, a requisite feature of primate subsistence, is lost to reproduction. Although metabolic energy expenditure can only be measured in extant species, using the equations of motion to calculate mechanical energy expenditure offers unlimited opportunities to explore energy expenditure, particularly in extinc...

Forest Fire Smoke Recognition Based on Gray Bit Plane Technology

Apply the separation principle of the physical contradictions in TRIZ into the simulation of forest fire smoke; propose a forest fire smoke recognition algorithm based on gray bit-plane. To get eight images of moving smoke, the separation process on smoke moving images is necessary; use high-diagram image (the 7th,the 8th image) to extract contours, and extract the contour of the remaining imag...

Xperimental Study of Froude Number Modeli

Obscuration of the Parsec Scale Jets in

We present results of VLA and VLBA observations of the 1.420 GHz neutral hydrogen absorption associated with the Compact Symmetric Object 1946+708 (z=0.101). We nd signiicant structure in the gas on parsec scales. The peak column density in the Hi (N HI '2.210 23 cm ?2 (Ts 8000K)) occurs toward the center of activity of the source, as does the highest velocity dispersion ((V FWHM '350 km s ?1)....
