INTERACTION OF A HELICAL BLADE OF A DRILLING TOOL WITH FROZEN GROUND by I. G. Martiuchenko, M. I. Zenin

“…The dependence of the destroyed soil volume and the relation of an obtained borehole diameter to a diameter of a destroying section of a helical blade according to the angle of bend of a helical blade radius at which its increment occurs is determined.Discussions and conclusion. It is established that a helical drilling tool performs a borehole drilling due to the tearing strain implementation, which makes it possible to achieve more efficient drilling and obtain a borehole diameter larger than a diameter of the destroying section of a helical blade.Financial transparency: the authors have no financial interest in the presented materials or methods. …”

Rough decision rules extraction and reduction based on granular computing by Hong-can YAN, Feng ZHANG, Bao-xiang LIU

“…Rule mining was an important research content of data mining,and it was also a hot research topic in the fields of decision support system,artificial intelligence,recommendation system,etc,where attribute reduction and minimal rule set extraction were the key links.Most importantly,the efficiency of extraction was determined by its application.The rough set model and granular computing theory were applied to the decision rule reduction.The decision table was granulated by granulation function,the grain of membership and the concept granular set construction algorithm gener-ated the initial concept granular set.Therefore,attribute reduction could be realized by the distinguish operator of concept granule,and decision rules extraction could be achieved by visualization of concept granule lattice.Experimental result shows that the method is easier to be applied to computer programming and it is more efficient and practical than the existing methods.…”
