On the basis of the scaling approach and CORSIKA simulations data the radial scale factor of the lateral distribution Sump Hose of electrons in extensive air showers is confirmed as a potentially effective primary mass estimator, and its sensitivity to hadronic interaction model is investigated.It is shown that improved composition results both on

A real-time monitoring system of brake clearance was designed based on PLC with high reliability and interference immunity and WinCC with BARLEY MALT friendly human-machine interface.General structure and software design of the system were introduced in details.The system has functions of data collecting,storing,analyzing and processing,and it has

Ultra-dense networks Soap represent the trend for future wireless 5G networks, which can provide high transmission rates in dense urban environments.However, a massive number of small cells are required to be deployed in such networks, and this requirement increases interference and number of handovers (HOs) in heterogeneous networks (HetNets).In s
