Oxygen-Improved Hard Coatings for High Performance Cutting Processes

Multicomponent Alloying for Improved Hard Coatings

Coatings are vital to protect and to increase the productivity of cutting tools in high speed and dry cutting applications. During the cutting operation the temperature may exceed 1000 oC it is therefore necessary that the coatings withstand high temperatures. A lot of development and research has been carried out during the last 30 years on finding new coating material systems providing enhanc...

Unitarity cutting rules for hard processes on nuclei

Heavy nuclei introduce a new scale into the pQCD description of hard processes on nuclei, the saturation scale, and the familiar linear k ⊥ –factorization breaks down. It is replaced by a new concept, the nonlinear k ⊥ –factorization. Here we give a brief overview how topological cross sections for hard processes on nuclei are obtained from nonlinear k ⊥ –factorization.

Unitarity Cutting Rules for Hard Processes on Nuclear Targets

It is a pleasure to present our results [1] here in Gatchina, where many of the fundamental ideas on the use of unitarity cutting rules perhaps originated [2]. Consider, for example, (not too) small-x deep inelastic scattering (DIS). On the free nucleon target, the qq̄ dipole will exchange a single gluon with the target and the recoiling nucleon debris will be in the color octet state. On a heav...

Fuzzy VIKOR Optimization for Designing High Performance Hydroxyapatite/Polycaprolactone Scaffolds for Hard Tissue Engineering

Combining fuzzy RES with GA for predicting wear performance of circular diamond saw in hard rock cutting process

Predicting the wear performance of circular diamond saw in the process of sawing hard dimensional stone is an important step in reducing production costs in the stone sawing industry. In the present research work, the effective parameters on circular diamond saw wear are defined, and then the weight of each parameter is determined through adopting a fuzzy rock engineering system (Fuzzy RES) bas...
