We consider the problem of fairly dividing a two dimensional heterogeneous good among multiple players. Applications include division of land as well as ad space in print and electronic media. Classical cake cutting protocols primarily consider a one-dimensional resource, or allocate each player multiple infinitesimally small “pieces”. In practice, however, the two dimensional shape of the allo...

The boom-type roadheader is the foremost mining equipment in coal mines. At present, automatic cutting technology still immature for adjusting speed automatically accordance with rock strength, resulting energy dissipation. In this study, we put forward a method respect to detecting geological strength index of seam profile through visual inspection, as well characterize and control head based ...

Abstract In this paper, taking a cutting tool as an example and aiming at the problem of stress fatigue evaluation optimization, finite element model including tool, shaft, washer was established by using methods simulation testing, strain analysis in working process completed. A single fluid-structure coupling method applied to calculate dynamic load high-speed food cutting, ABAQUS used analyz...

In this study, turning operation of Monel K500 copper-nickel super-alloy was evaluated. Ceramic cutting tools with two different cutting noses (conventional and wiper) were utilized. At first, the experimental tests were designed by using central composite design method. After implementation of the tests, the statistical models for output data (surface roughness, cutting force, and flank wear) ...
