The results of the laboratory water permeability tests a sand modified by saponite clay fraction from diamond mining industry waste are presented. filtration suspension through landfill ground bed as method additive enrichment is approved. experimental apparatus consisted triaxial test chambers and semi-automatic devices for supplying. excluded sidewall leakage in samples provided required valu...

We present an interactive sand art drawing system using one RGB-D sensor, such as Kinect. Our system supports the common sand drawing functions, such as sand erosion, sand spilling, and sand leaking. To use hands to draw virtual sand on a drawing plane, we design four key gestures which enable drawing manipulation actions for sand. The basic idea is that the gesture of one hand controls the dra...

The Trauzl test is widely used to measure the explosive power of a substance by determining volume increase produced detonation tested charge in cavity lead block with defined quality and size. In this study, high-speed 3D digital image correlation (3D-DIC) system were evaluate effect stemming on blast hole. blasting experiments conducted emulsion explosives. materials adopted study sand, aggre...
