Direct and large eddy simulations are performed to study the internal waves generated by the oscillation of a barotropic tide over a model ridge of triangular shape. The objective is to go beyond linear theory and assess the role of nonlinear interactions including turbulence in situations with low tidal excursion number. The criticality parameter, defined as the ratio of the topographic slope ...

The machining process using a combination of steep and shallow strategy is the most widely used for finishing on complex models that have many areas walls floors. Using single entire model can lead to long times poor surface finish quality. efficiently detect parts contours those contours. In other words, this analyze angle at runtime identify divide zone based slope or commonly called threshol...

This paper presents an improved slope stability sensitivity analysis (ISSSA) model that takes anchoring factors into consideration in umbrella-anchored sand and clay slopes under reservoir water level fluctuation. The results of the ISSSA show inclination layout density anchors are main controlling for fluctuation level, while head height Cangjiang bridge—Yingpan Yunnan province China. Moreover...

Abstract In current research, a novel geometrical technique is introduced to estimate the length ( L ) of sliding arc by considering slip surface entry point distance d e ). Morgenstern-Price limiting equilibrium and strength reduction methods are selected within framework SLOPE/W FLAC 3D softwares respectively, study mechanism stability-effecting factor for loose rock slope comprise two differ...

Shallow buried and unsymmetrically loaded tunnel is the most common type of mountain portal. Currently, studies mainly focus on stability side slope, while investigation deformation front slope after excavation relatively less. In this paper, influence gradient angle between portal was analyzed by FLAC3D. The results show that: When greater than 40°, caused larger with increase angle. order to ...

In this study, we found that the optimum take-off angle for a long jumper may be predicted by combining the equation for the range of a projectile in free flight with the measured relations between take-off speed, take-off height and take-off angle for the athlete. The prediction method was evaluated using video measurements of three experienced male long jumpers who performed maximum-effort ju...

Mechanical machining processes are common manufacturing strategies to re-shape materials to desired specification. The mechanistic approach has revealed the mechanics of the machining processes with various parameters determined. The aim of this work is to investigate the impact of swept angle optimization and their influence on the specific cutting energy in milling AISI 1045 steel alloy. This...

The action of bull seminal plasma .5’-nucleotidase on adenosine 5’-phosphate in the presence of magnesium has one optimum at pH 7.5 to 8.0 and a second at pH 9.1 to 9.3. Only one optimum, at pH 7.5 to 8.0, occurs in the absence of magnesium. The phenomenon of a double pH optimum was independent of the nature of the buffer that was employed. A magnesium concentration of 0.005 to 0.01 M and a tem...
