Traditional slope stability analysis is limited to the use of single valued parameters to analyze a slope‟s characteristics. Consequently, traditional analysis methods yield single valued estimates for factor of safety of a slope‟s stability. However, the inherent variability of the soil characteristics which affect slope stability indicates that the stability of a slope is a probabilistic rath...

Geocell protective slope is a kind of important ecological protection form, which is widely used in the geotechnical engineering field. Based on the finite element software ABAQUS, and combining with protective slope body’s mechanics performance in shallow soil, the finite element model of geocell slope protection is established under the conditions of rainfall seepage, and then we simulate the...

A water surface slope limiting scheme is tested and compared with the water depth slope limiter for the solution of one dimensional shallow water equations with bottom slope source term. Numerical schemes based on the total variation diminishing RungeKutta discontinuous Galerkin finite element method with slope limiter schemes based on water surface slope and water depth are used to solve one-d...

by Craig Abram Jordan, M.S. Washington State University Chair: Balasingam Muhunthan Landslides constitute a major geological hazard in the world due to their high financial cost and their nondiscriminatory nature. The Olympic Region of Washington State has many potential triggers of landslides, but prolonged periods of high rainfall is the most commonly attributed trigger of landslides. The cur...

'Fear' is used scientifically in two ways, which causes confusion: it refers to conscious feelings and to behavioral and physiological responses. Restricting the use of 'fear' to denote feelings and using 'threat-induced defensive reactions' for the responses would help avoid misunderstandings about the brain mechanisms involved.

We develop a mixture procedure for multi-sensor systems to monitor data streams for a change-point that causes a gradual degradation to a subset of the streams. Observations are assumed to be initially normal random variables with known constant means and variances. After the change-point, observations in the subset will have increasing or decreasing means. The subset and the rate-of-changes ar...

the location of extracellular enzyme activities in soil aggregates can be influenced by slope position. this study aims to determine the effect of slope position on aggregate distribution of organic c and l-glutaminase activity. the soils were collected from different slope positions (shoulder, backslope, footslope and toeslope) at two pasture ecosystems (fereydoonshahr and chelgerd, central ir...

Slope distance was measured between the top of 30 light poles and their respective ground level coordinate identified within a central parking lot on the campus of Stephen F. Austin State University, Nacogdoches, Texas. Slope distance measured using Pictometry® hyperspatial 4-inch (10.2 centimeters) multispectral imagery within a web based interface was compared to in situ total station and tap...

BACKGROUND AND OBJECTIVES Randomized clinical trials on progression of renal diseases usually include patients according to criteria for BP, renal function, and proteinuria. There are no data showing that this provides groups with similar baseline rates of renal function loss. Accordingly, the impact of preintervention rate of renal function loss (slope) on outcome of studies has not been estab...
