This study investigates the distributions of velocity and Reynolds stress in an artificial pool-riffle sequence for two entrance slopes 5° 20° a laboratory compares results with similar gravel-bed river central Iran. Quadrant analysis is applied to find out contributions different events on turbulent flow structures. At slope 5°, distribution follows exponential trend without separation, but 20...

A critical aspect of perception-action coupling is the ability to modify ongoing actions in accordance with variations in the environment. Infants' ability to modify their gait patterns to walk down shallow and steep slopes was examined at three nested time scales. Across sessions, a microgenetic training design showed rapid improvements after the first session in infants receiving concentrated...

Agroforestry solutions offer better use of disadvantaged agricultural land. Steep slopes and the constant risk game damage are not conducive to agriculture. On slopes, cost machine operating hours is higher than on plane areas, machines also wear out faster due loads. Varied topography, steep deep valleys characterize examined Zselic hills. There typical forest management that results in opport...

Bogor, Cianjur, and Sukabumi areas of West Java Province, Indonesia, are vulnerable landslide areas. This study analyzes the characteristic factors affecting landslides. The analysis was carried out on 148 landslides from 415 2018-2020 landslides, which were selected purposively by considering heterogeneity soil, geology, slope classes, land use type, accessibility locations. Landslide characte...

In this paper several rate R = 2/5 convolutional encoding matrices with four states are used to illustrate how unequal error protection can be achieved for the different positions in the code sequences as well as in the information sequences. Free outputand input-distances and active burst outputand input-distances are computed. Typically a single code cannot combine a large free outputor input...

We design two performance measures for a planar locomotion robot, modeled closely after the Platonic Beast. The first measure is proportional to the total motion of all joints during locomotion of the robot. This is a rough approximation to the energy consumption of the robot. The second measure determines the maximal speed of locomotion, for given limits on the joint speeds. We compute optimal...
