,M?ssbauer Spectroscopy — Nuclear Gamma Resonance,lear state are easily observed by using the resonance spectroscopy of the gamma rays emitted in a nuclear transition toward the ground state for an isotope of the element in question. Nuclear gamma resonance (NGR), is possible only for solids, as was shown by M?ssbauer in 1957. It is illustrated in

Optimum Beam Bandwidth Allocation Based on Traffic Demands for Multi-spot Beam Satellite System-spot beam satellite system, as beam bandwidth to be allocated is controlled dynamically. We apply the Lagrange theory to obtain the optimization formula for bandwidth allocation of each spot beam in order to meet the total bandwidth constraint. Eventually we can find out the optimum beam profile respect to bandwidth.
