We present a systematic study of fast neutrino-flavor conversion (FFC) with both small-scale and large-scale numerical simulations in spherical symmetry. find that FFCs can, general, reach quasisteady state, these features the nonlinear phase are not characterized by growth rate FFC instability but rather angular structures electron neutrino lepton number (ELN) heavy one. Our result suggests ne...

Computational cost of metaheuristic based optimum design algorithms grows excessively with structure size. This results in computational inefficiency of modern metaheuristic algorithms in tackling optimum design problems of large scale structural systems. This paper attempts to provide a computationally efficient optimization tool for optimum design of large scale steel frame structures to AISC...
