Tillage is one of the most important practices affecting soil physical and hydraulic properties. Its effects may vary intensely according to tillage method. This study aims evaluate different methods (moldboard plow+disk harrow, moldboard plow+rotary tiller chisel harrow) drainage (subsurface non-drainage) on properties in a clay loam soil. The experiment was conducted split-plot time statistic...

Nowadays, one of the main tasks of Ukrainian coal industry is increasing labour productivity by means of complex mechanization and automatization of mining operations with usage of modern equipment. The best example is implementation of modern plow complexes on Western Donbas mines, PJSC “DTEK Pavlogradvugillia”. Currently, plowing is one of perspective directions of coal extraction development...

We consider the problem of finding all enclosing rectangles of minimum area that can contain a given set of rectangles without overlap. Our rectangle packer chooses the xcoordinates of all the rectangles before any of the y-coordinates. We then transform the problem into a perfect-packing problem with no empty space by adding additional rectangles. To determine the y-coordinates, we branch on t...
