Diagnosing GRB Prompt Emission Site with Spectral Cut-Off Energy
The site and mechanism of gamma-ray burst (GRB) prompt emission is still unknown. Although internal shocks have been widely discussed as the emission site of GRBs, evidence supporting other emission sites, including the closer-in photosphere where the fireball becomes transparent and further-out radii near the fireball deceleration radius where magnetic dissipation may be important, have been a...
متن کاملSTUDY OF NUCLEAR LEVEL DENSITY AND SPIN CUT-OFF FACTORS
Nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹A‹63,from a microscopic theory, which includes nuclear pairing interaction. Single particle levels for both Seeger and Nilsson potentials were used in the calcdations. Level densities extracted from the theory are compared with their conesponding experimental values, It is found that the overall...
متن کاملCut-off Grade Optimization for Maximizing the Output Rate
In the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. Since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. Different goals may be used for determining optimum cut-off grade. One of...
متن کاملOptimal High Frequency Cut-off in SWAN Wave Model
This study investigates the importance of selecting an appropriate cut-off frequency in the SWAN model when it is applied to areas with limited fetches. In SWAN, the cut-off frequency is a constant value set by user in the model, and its appropriate selection plays an important role in the accuracy and optimization of the wave model; very high value increases the computational cost and might le...
