The POXR and SMR methods adopted in producing hydrogen from methane gas are simulated and exergy analysis of both the processes are run for comparison. The effective parameters of the feeding materials ratio and the system temperature for maximizing hydrogen production and increasing efficiency are assessed here. Influenced by the changes in these parameters the unit efficiency is increased up ...

The effect of sample size on the melting parameter of simulated potassium chloride microcrystal is investigated by molecular dynamics simulation. The size of microcrystal is varied from 8 to 4096 ions. The increase in melting temperature with sample size was found to be in good agreement with the theory.

Heavy quark potentials are investigated at high temperatures. The temperature range covered by the analysis extends from T values just below the deconfinement temperature up to about 4Tc in the deconfined phase. We simulated the pure gauge sector of QCD on lattices with temporal extents of 4, 6 and 8 with spatial volumes of 32. On the smallest lattice a tree level improved action was employed w...

in this research work, the dissolution of chalcopyrite was investigated under atmospheric pressure, with sulfate media at low temperatures, in 30°c to 50°c. in the galvanic interaction between chalcopyrite and pyrite, pyrite is used as a leaching catalyst. effects of different parameters such as temperature, stirring speed, pyrite to chalcopyrite ratio, particle size, and solution potential wer...

The coalescent properties of ZnO clusters were studied through experiment and molecular dynamics simulation in combination with the tightbinding potential and ZnO potential. The results from the simulation show that the linearly relationship between the melting temperature and the function of atom numbers of N was obtainable. Extrapolating the result yield at a melting point of 2130 K for N/N (...

It is a long time that the Simulated Annealing (SA) procedure is introduced as a model-free optimization for solving NP-hard problems. Improvements from the standard SA in the recent decade mostly concentrate on combining its original algorithm with some heuristic methods. These modifications are rarely happened to the initial condition selection methods from which the annealing schedules start...

The glassy-winged sharpshooter, Homalodisca vitripennis (Germar), vectors the bacterium Xylella fastidiosa that induces Pierce's disease of grape. This study determined the effect of temperature on the feeding activity of H. vitripennis adults and the resulting production of excreta. The Logan type I model described a nonlinear pattern that showed excreta production increased up to an optimal ...

We review a model{based rather than phenomenological approach to low{temperature anomalies in glasses. Speciically, we present a solvable model inspired by spin{glass theory that exhibits both, a glassy low{temperature phase, and a collection of double{ and single{well conngurations in its potential energy landscape. The distribution of parameters characterizing the local potential energy conng...
