This aspect is commonly denoted as zig-zag effect and it is generally given by the choice of different materials along the transverse direction of the structure. For instance, this effect is particularly evident when a soft-core is included into the lamination scheme of a generic plate or ...
The subsidence prediction model of the thick loose layer is constructed according to the principle of equal influence superposition: the hyperbolic secant subsidence prediction model. The model has a high prediction accuracy in the thick loose layer mining area. It provides data support for the ...
sure, it's harder to create, produce, and ship such impossibly huge comforters that are "thicker than thick"... but isn't that the whole point? with the number of hours, we sleep (or should sleep) each night, it should be a crime to have a flat sheet-like comforter. our thicker...
The deformation of the roadway was controlled within a safety zone. The application of this technology reduced the repair rate of the roadway and improved the efficiency of the roadway excavation. It brought significant economic benefits and provides an important reference for similar mines. Keywords:...
