although some 3d slope stability algorithms have been proposed in recent three decades, still role of pore pressures in three dimensional slope stability analyses and considering the effects of pore water pressure in 3d slope stability studies needs to be investigated. in this paper, a limit analysis formulation for investigation of role of the pore water pressure in three dimensional slope sta...

Decimeter-scale early-stage aeolian bedforms represent topographic features that differ notably from their mature dune counterparts, with nascent forms exhibiting more gently sloping lee sides and a reverse asymmetry in flow-parallel bed profile compared to dunes. Flow associated the development of these “protodunes,” wherein crest gradually shifts downstream towards its state, was investigated...

ABSTRACT- Measurement of irrigation water in agricultural areas is necessary, especially, in arid and semi-arid regions. Long-throated flumes have been used to measure irrigation water and are known to be inexpensive devices with high performances. In these structures, head-discharge tables are predicted theoretically with no need to calibrate. In this study, the model of LOTF ...

Three experiments investigated whether 14- and 15-month-old infants use information for both friction and slant for prospective control of locomotion down slopes. In Experiment 1, high- and low-friction conditions were interleaved on a range of shallow and steep slopes. In Experiment 2, friction conditions were blocked. In Experiment 3, the low-friction surface was visually distinct from the su...

We explicitly compute all the slopes of the Hecke operator U2 acting on overconvergent 2-adic level 1 cusp forms of weight 0: the nth slope is 1 + 2v((3n)!/n!), where v denotes the 2-adic valuation. We formulate an explicit conjecture about what these slopes should be for weight k forms.

We show that every cubic graph can be drawn in the plane with straight-line edges using only the four basic slopes {0, π/4, π/2, 3π/4}. We also prove that four slopes have this property if and only if we can draw K4 with them.

Nekrasov's integral equation describing water waves of permanent form, determines the angle φ (s) that the wave surface makes with the horizontal. The independent variable s is a suitably scaled velocity potential, evaluated at the free surface, with the origin corresponding to the crest of the wave. For all waves, except for amplitudes near the maximum, φ (s) satisfies the inequality |φ (s) | ...

BACKGROUND Percutaneous transforaminal techniques for the treatment of lumbar disc herniation have markedly evolved. Percutaneous endoscopic lumbar discectomy (PELD) for L5-S1 disc herniation is regarded as challenging due to the unique anatomy of the iliac crest, large facet joint, and inclinatory disc space. Among these, the iliac crest is considered a major obstacle. There are no studies reg...

The mean overtopping discharge and the flow parameters related to individual events are often used characterize wave processes at dikes. Roughness, berms oblique waves have significant effects on dikes while these still not fully understood. A 2DV OpenFOAM® model is validated using experimental data for predicting velocity layer thickness waterside edge of crest. numerical then applied investig...

In highway slopes (HWS) constructed on high expansive clay soil (HECS), in situ moisture variation is an environmentally driven variable that can significantly impact the safety of soil. Electrical resistivity imaging (ERI) a non-destructive method with considerable potential for subsurface mapping, which be correlated volumetric content (VSMC) and matric suction (SMS) HECS to remarkably enhanc...
