This paper demonstrates the ability of Shear Strength Reduction (SSR) analysis based on the Finite Element Method (FEM) to model the scale effects of discontinuity networks on the stability and failure mechanisms of slopes in blocky rock masses. Through three examples, it shows how these mechanisms depend on joint network geometry and change with increasing slope height. Introduction Scale Effe...

In layered and blocky rock slopes, toppling failure is a common mode of instability that may occur in mining engineering. If this type of slope failure occurs as a consequence of another type of failure, it is referred to as the secondary toppling failure. “Slide-head-toppling” is a type of secondary toppling failures, where the upper part of the slope is toppled as a consequence of a semi-circ...

In this paper attempts have been done to create a mortar with relatively high uniaxial compressive strength (UCS), easy casting, high flexibility, instant hardening, low cost and easy availability. The main use of this material is to physically model the mechanical behavior of jointed rock-like blocks. The effect of four parameters such as joint roughness coefficient (JRC), bridge length (L), b...

A Zöldségtermesztési Kutatóintézet paprikafajtákat szeretne észak-afrikai országokba exportálni, ahol nagyon magas a talajok sótartalma. Magyarországon is sok helyen és az öntözővíz Ezért vizsgáltuk két paprika fajtatípus (blocky hegyes erős) négy-négy fajtájának palántakori sóstressz érzékenységét talajnélküli körülmények között. kiváltása előtt mértük fajták nettó fotoszintézis intenzitásának...

d image in the discrete cosine transform (DCT) omain can generate blocky artifacts in the outs a put image. It is possible to reduce these artifact nd RMS error by adjusting measures of block g t edginess and image roughness, while restrictin he DCT coefficient values to values that would d i have been quantized to those of the compresse mage. We also introduce a DCT coefficient . amplitude adj...
