The study of the nival-glacial objects Munku-Sardyk Range (East Sayan) as good long-term indicators climate development has been going on for more than 100 years. In addition to most studied glaciers Peretolchin glacier and second largest Radde glacier, found various transitional glacial-permafrost formations permafrost-ice-rock buried glaciers, which in area were virtually un explored. One suc...

This paper describes a two-dimensional computer simulation study of the impact induced breakage of brittle solid particles. The work started as an attempt to understand the effect of impact velocity on the induced breakage and in particular to explain why there is a shift in the slope of the size distribution at large impact velocities. The results indicate that the observed breakage pattern is...

in this study the wavelet neural network (wnn) and artificial neural network (ann) were used to simulate barley breakage percentage in combine harvester. the models have been trained using the same data conditions. air temperature, thresher cylinder speed, distance between thresher cylinder and concave (back and forth) and the percentage of barely moisture were as the input variables. the resul...

Particle fracture, the formation of small particles as result breakage large ones, and aggregation, combination have important implications in industry (e.g. food processing, pharmaceutical production) geophysics (e.g., snow avalanches rock debris flows). Also, presence different size that from fracture aggregation can induce segregation, resulting migration to regions flow. Here, we formulate ...

Abstract Uncertain climate change is a natural phenomenon that common nowadays. Soil the result of weathering rocks and one causes this weathering. Residual soil formed on top original rock layer. In addition to parent rock, also affects residual soil, both in terms grain size shear strength. This modeling was carried out by giving wet-dry treatment tuff samples at Institut Teknologi Sumatera (...

Fracture initiation and propagation in fluid-saturated rocks are controlled by interaction between fluid flow rock deformation. The description of hydromechanical coupling is essential for modeling the fracture process. In this paper, an improved model proposed framework particle simulation method. This provides a better hydraulic properties before after breakage bonds can efficiently describe ...
