Deep Tempering

CoRR, 2014
Restricted Boltzmann Machines (RBMs) are one of the fundamental building blocks of deep learning. Approximate maximum likelihood training of RBMs typically necessitates sampling from these models. In many training scenarios, computationally efficient Gibbs sampling procedures are crippled by poor mixing.

Hydrogen Diffusivity and Hydrogen Traps Behavior of a Tempered and Untempered Martensitic Steel

Hydrogen
The effect of tempering temperature and tempering time on the density of hydrogen traps, hydrogen diffusivity, and microhardness in a vanadium-modified AISI 4140 martensitic steel was determined. Tempering parameters were selected to activate the second,

Evolution of microstructure and mechanical properties during tempering of M50 steel with Bainite/Martensite duplex structure

Journal of Materials Research and Technology, 2020
The evolution of microstructure and mechanical properties during tempering of M50 steel with bainite/martensite (B/M) duplex structure have been investigated. The microstructural observation shows that the redistribution of carbon atoms and precipitation

Resistance to Pitting Corrosion in Steels Based on the Fe-Cr-Ni-C System [PDF]

Materials Research, 2017
This study aimed to investigate the effects of difference in nickel content and the tempering temperatures on the corrosion resistance in 13Cr2Ni0.1C and 13Cr1Ni0.15C steels. Results showed that passive film in 13Cr2Ni0.1C steel is formed more quickly at

Monte Carlo Methods for Rough Free Energy Landscapes: Population Annealing and Parallel Tempering

, 2011
Parallel tempering and population annealing are both effective methods for simulating equilibrium systems with rough free energy landscapes. Parallel tempering, also known as replica exchange Monte Carlo, is a Markov chain Monte Carlo method while ...

Effects of 27.12 MHz Radio Frequency on the Rapid and Uniform Tempering of Cylindrical Frozen Pork Loin (Longissimus thoracis et lumborum)

Food Science of Animal Resources, 2017
Quality characteristics of frozen cylindrical pork loin were evaluated following different tempering methods: 27.12 MHz curved-electrode radio frequency (RF) at 1000 and 1500 W, and forced-air convection (FC) or water immersion (WI) at 4°C and 20°C.
