In order to systematically reveal the dynamic response characteristics of rock mass slopes subject seismic excitation, time-domain and frequency-domain analyses are used investigate a bedded slope from multiple perspectives, using two-dimensional numerical analyses. Based on simulation results, influence weak structural planes propagation waves in is analyzed. The analysis suggests that topogra...

landslides and slope instabilities are major hazards for human activities often causing economiclosses and property damages. sikan river basin (ilam province) due to the topography, tectonic,lithology, and climate has enough potential for occurrence of this phenomenon. the objectives of thisstudy were to determine effective parameters controlling the landslide occurrence and to preparezonation ...

Experiments with the insect ectoderm have suggested that planar polarity in epithelia results from the local orientation of cells to the slope of a gradient of positional information. Here we show that planar polarity in the Drosophila eye is inverted when the morphogenetic wave that sweeps through the presumptive retinal epithelium is induced to move in the reverse direction. We suggest that t...

This paper examines the relevance of parameters related to slope and end-point of pitch segments for indicating turn-taking intentions in Swedish. Perceptually motivated stylization in Prosogram was used to characterize the last pitch segment in talkspurts involved in floor-keeping and turnyielding events. The results suggest a limited contribution of pitch pattern direction and position of its...

The linear stability of rapid granular flow on a slope under gravity is analyzed using hydrodynamic equations. It is demonstrated that the steady uniform flow becomes unstable against the long-wavelength perturbations longitudinal to the flow direction for a certain parameter range to form the density wave. The results are compared with our previous molecular dynamics simulations (Mitarai & Nak...

The spatial variation of soil physical and chemical properties in Funiu Mountain was studied to provide references for identifying soil spatial variation mechanism in bordering land of China warm temperate zone and northern subtropical region. Using vertical gradient sampling and traditional statistics method, the soil samples at the altitude from 1640 m to 1870 m were collected to compare phys...

conclusions the x-intercepts (point at which the fdc crosses the x-axis) were on average more in the base-in direction, y-intercepts (point at which the fdc crosses the y-axis) were shifted in the exo direction, and slopes were steeper in the symptomatic group. results there were more subjects with exo fixation disparity than eso fixation disparity in the study sample. the means for fixation di...

this research was conducted in a part of the dry farming lands of the southern guilan province, aimed at examining the impact of tillage erosion on the soil displacement and consequently its productivity. in order to achieve the research aims, 18 sampling points were spotted in some different locations of the landscape in seven adjacent fields, based on the adjacency to the field ridges (border...

Numerical studies of internal wave reflection from sloping boundaries are presented. Previous work (Slinn and Riley, 1996, 1998a, 1998b, 1999) has restricted attention to internal waves that approach the bottom slope in a plane normal to the boundary (normal incidence). This work extends the scope of the three-dimensional time-dependent numerical experiments to examine internal waves that appro...

In this paper, an efficient structural approach for recognizing on-line handwritten digits is proposed. After reading the digit from the user, the coordinates (x, y) of the pixels representing the drawn digit are used for calculating and normalizing slope values of these coordinates. Successive slope values are then used to record the change of direction which used to estimate the slope. Based ...
