This work describes the optimization of cryogenic treatment (CT) parameters such as the cooling rate, the soaking temperature, the soaking time, the tempering temperature and the tempering time to maximise the tool wear of high speed steel tools in dry turning of AISI 316 grade austenitic stainless steels by Taguchi method. For this purpose, four iteration of Taguchi design (L16) have been used...

In recent years, digital forensics emerged as a powerful and promising discipline to identify, detect and authenticate the digital images. This could be the authentic ground to present a proof of tempering as evidence in the court of law. The trust we have had till now in believing what we see started eroding. This is all happening due to the availability of the low cost, sophisticated yet easy...

We study the efficiency of parallel tempering Monte Carlo technique for calculating true ground states of the Edwards-Anderson spin glass model. Bimodal and Gaussian bond distributions were considered in two and three-dimensional lattices. By a systematic analysis we find a simple formula to estimate the values of the parameters needed in the algorithm to find the GS with a fixed average probab...

The tempering of two–phase mixtures of bainitic ferrite and carbon–enriched retained austenite has been investigated in an effort to separate the reactions that occur at elevated temperatures from any transformation during cooling to ambient conditions. It is demonstrated using synchrotron X–radiation measurements, that the residue of austenite left at the tempering temperature partly decompose...

The quality traits of a single grain kernel can produce an index of the overall quality of the bulk grain, as individual kernels comprise a grain bulk. Therefore, single–kernel drying behavior is important in understanding the overall quality of grain. A Matlab based software package with C++ compiler was developed in this study for describing single–kernel drying, tempering, and internal stres...

Parallel Tempering (PT), also known as Replica Exchange, is a powerful Markov Chain Monte Carlo sampling approach which aims at reducing the relaxation time in simulations of physical systems. In this paper, we present a novel implementation of PT, so-called decentralized replica exchange PT, using MPI and the Scalable Parallel Random Number Generators (SPRNG) libraries. By adjusting the replic...

The microstructure evolution and tempering transformation kinetics of the M50 steel subjected to cold ring rolling (CRR) have been investigated. results indicate that brass R{110}<110> texture is weakened with enhancement <111>//ND during CRR. Due increased low angle boundaries by CRR, Ac1 temperature decreases while carbon content volume fraction RA increase. During tempering, activation energ...
