This adaptation, that we shall call Parallel Tempering with Equi-Energy Moves (PTEEM), keeps the original idea of the EES method while ensuring good theoretical properties, and practical implementation even if combined with a Gibbs sampler. Performances of the PTEEM algorithm are compared with those of the EES and of the
In-line shear-mixing process. We used an in-line shear mixing system (Silverson) to produce graphene flake dispersions (Fig. 1) -line shear mixing is an enclosed, cyclic process where the rotor
One of the approaches to sustainable energy supply is underground natural gas storage (UGS). In UGS, the gas in the underground storage is made up of two fractions, namely base gas (cushion gas) and working gas. The base gas is injected into the reservoir to maintain the pressure and stays there until the end of the storage period.
The Equi-Energy Sampler (EES) introduced by Kou et al [2006] is based on a population of chains which are updated by local moves and global moves, also called equi-energy jumps. The state space is partitioned into energy rings, and the current state of a chain can jump to a past state of an adjacent chain that has energy level close to its
This work proposes an adaptation of the Equi-Energy Sampler that combines PT with the principle of swapping between chains with the same level of energy, and keeps the original idea of the EES while ensuring good theoretical properties, and practical implementation. The Equi-Energy Sampler (EES) introduced by Kou et al. (in
Tempering is a critically important process in the manufacture of heat-treated steel parts, particularly if high hardness is desired. The technique is an ancient one. It was developed by swordsmiths through the early Iron Age, as they forged and hardened Iron weapons in barely understood processes that made primitive steels.
The Equi-Energy Sampler (EES) introduced by Kou et al. (in Ann. Stat. 34(4), 1581–1619, 2006) is based on a population of chains which are updated by local moves and global moves, also called equi-energy jumps. The state space is partitioned into energy rings, and the current state of a chain can jump to a past state of an adjacent
The model is found to represent buoyancy and mixing in the storage tank in a realistic way and to correspond well to experimental results. To allow researchers to assess the uncertainty on performance indicators in building energy simulations, an effective storage capacity ratio is defined and its variation within the model parameter

Thermochemical storage possesses high energy density and negligible heat loss, which potentially offers a long-term storage option with relatively small storage volume. The sorption process is usually able to store low and medium grade heat at a temperature of less than 400 °C and the heat of reaction is typically between 20 and 70

Thermocline thermal-energy storage (TES) suffers from so-called thermocline degradation, which refers to the flattening of temperature gradients in the TES with successive charging-discharging cycles. During discharging with the mixing method, the storage is operated in an analogous manner, see Fig. 6 (c) and (d). Instead of

Polymer dielectrics need to operate at high temperatures to meet the demand of electrostatic energy storage in modern electronic and electrical systems.

How They Work. A single-family storage water heater offers a ready reservoir -- from 20 to 80 gallons -- of hot water. It operates by releasing hot water from the top of the tank when you turn on the hot water tap. To replace that hot water, cold water enters the bottom of the tank through the dip tube where it is heated, ensuring that the tank
