STUDY 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 کاملBlocking Conductance and Mixing in Random Walks
The notion of conductance introduced by Jerrum and Sinclair [8] has been widely used to prove rapid mixing of Markov Chains. Here we introduce a bound that extends this in two directions. First, instead of measuring the conductance of the worst subset of states, we bound the mixing time by a formula that can be thought of as a weighted average of the Jerrum-Sinclair bound (where the average is ...
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...
متن کاملOn Generalizing the Cut-off Phenomenon for Random Walks on Groups
There has been a lot of recent work on the convergence of random walks on finite or compact groups to their stationary, uniform distribution. Particular emphasis has been placed on the rate of convergence, i.e. on estimates of the number of iterations until the random walk is “close” to uniformity. The best-known examples come from the cardshuffling analyses of Diaconis and co-workers; see [D] ...
