In the present study, we use various spatial fuels data within a coupled atmospherewildfire model to compare the simulated fire behavior for a small portion of the16,000 acre Calabasas fire that occurred on 21-22 October 1996 in the Santa Monica Mountains of Los Angeles County (Bamattre et al., 1997). The fire simulation investigates an intense fire that occurred in an isolated canyon around no...

What do infants learn when they learn to sit upright? We tested behavioral flexibility in learning to sit-the ability to adapt posture to changes in the environment-in 6- to 9-month-old infants sitting on forward and backward slopes. Infants began with slant at 0°; then slant increased in 2° increments until infants lost balance. Infants kept balance on impressively steep slopes, especially in ...

A large body of work has been devoted to the accurate detection and simulation wave breaking in coastal areas. It is a key process for wide range engineering activities environmental issues. This motivated development variety onset criteria, such as kinematic criteria based on maximum value (usually unity) ratio uc/c, horizontal particle velocity at crest uc its phase c, both taken direction pr...

Three-dimensional analysis of stability is carried out for slopes with the failure mechanism confined to a narrow space. A curvilinear cone surface modified by removing slice from its central portion, make fit in The resulting no longer smooth, and it referred as ridge distinct surface. based on appears yield lower factors than mechanisms used geotechnical engineering thus far. Kinematic limit ...

In uncertain situations such as descending challenging slopes, social signals from caregivers can provide infants with important information for guiding action. Previous work showed that 18-month-old walking infants use social information selectively, only when risk of falling is uncertain. Experiment 1 was designed to alter infants' region of uncertainty for walking down slopes. Slippery Teflo...

In the percutaneous method, the incision is below the crest, through the muscle bulk of the glutei. In the open method it usually lies over the crest. The percutaneous incision is smaller, and less likely to damage the subcutaneous nerves passing over the cres...

An analytical three-dimensional slope reliability evaluation framework was developed in this work independent of use numerical simulations. The stability analysis necessarily carried out by utilizing an extended Morgenstern–Price method, which characterized formulations and competitive computational efficiency. Incorporation the presented method into response surface methodology led to effectiv...

Neural tubes whose neural crest had just begun migration were isolated from stage-14 chick embryos, cleaned with 0.1% trypsin, and cultured in transparent hydrated collagen lattices (HCL) in an effect to stimulate in part the three-dimensional environment through which neural crest cells migrate in situ, in the embryo. The concentration of collagen in the lattices varied from 50 microgram/ml to...

We study straight-line drawings of graphs with few segments and few slopes. Optimal results are obtained for all trees. Tight bounds are obtained for outerplanar graphs, 2-trees, and planar 3-trees. We prove that every 3-connected plane graph on n vertices has a plane drawing with at most 5n/2 segments and at most 2n slopes, and that every cubic 3-connected plane graph has a plane drawing with ...
