Abstract Grinding the flutes of cemented carbide end mill cutters results in high and uneven radial wear grinding wheel. This is a consequence varying geometrical contact conditions over wheel width. Decreased manufacturing accuracy regarding tool target geometry consequence. To compensate for this, dressing intervals must be shortened. High non-productive times an additionally reduction layer ...

A preconditioned five-equation two-phase model coupled with an interface sharpening technique is introduced for simulation of a wide range of multiphase flows with both high and low Mach regimes. Harten-Lax-van Leer-Contact (HLLC) Riemann solver is implemented for solving the discretized equations while tangent of hyperbola for interface capturing (THINC) interface sharpening method is applied ...

Since Web 2.0, online content has become social. The popularization of Internet access added to the ease of producing online content have brought social communities to go online. This penetration of social assets in the modern internet has a wide impact, which naturally led computer scientists to analyze these online social networks. The promise of this research is for instance, from a network ...

The regular production of a satisfactory edge on a microtome knife for the cutting of sections as thin as 2 u, which are free from scores and other blemishes, is a serious technical problem in histological laboratories. Eyen when a good edge is produced on a knife, its life is generally limited because contact with any hard material in the specimen may damage the delicate edge, causing it to sc...

This paper develops a contest model of a professional sports league in which clubs maximize a weighted sum of profits and wins (utility maximization). The model analyzes how more win-orientated behavior of certain clubs affects talent investments, competitive balance and club profits. Moreover, in contrast to traditional models, we show that revenue sharing does not always reduce investment inc...

For mapping or object identification, the edges possess important information. It would be desirable to preserve the edges in the original image, while applying smoothing filter to reduce the influence of noise. A number of filters are available for this purpose, including the Mean Filter, Median Filter, Kuwahara Filter, and Symmetric Nearest Neighbor Filter (SNNF). This study investigates the ...
