This paper classifies hybrid dataflow techniques due to the instruction issuing technique. A software simulation is conducted to compare fine-grain dataflow to several hybrid dataflow techniques: multithreaded dataflow with direct token recycling as used in Monsoon, multithreaded dataflow with consecutive execution of the instructions within a thread as used in the Epsilon processors and in EM-...

We present a discrete element model for the simulation, at the grain scale, of gas migration in brine-saturated deformable media. We account rigorously for the presence of two fluids in the pore space by incorporating grain forces due to pore fluid pressures, and surface tension between fluids. The coupled model permits investigating an essential process that takes place at the base of the hydr...

Using different homogenization treatments, different initial microchemistry conditions in terms of solid solution levels of Mn, and number densities and sizes of constituents and dispersoids were achieved in an Al-Mn-Fe-Si model alloy. For each homogenized condition, the microchemistry and microstructure, which further change both during deformation and subsequent annealing, were quantitatively...

Grain size and microstructural features of cast superalloy K4169 were investigated under various melting and casting conditions together with the addition of grain refiners. It is found that lowering the pouring temperature and adding refiners to the melt before pouring can lead to grain refinement of matrix and improve the proportion of equiaxed grains. At a conventional pouring temperature of...
