The study of sub-1 GHz wireless channels in wooded hilly terrain (WHT) holds significant importance for the deployment and optimization emergency communication systems. In this paper, we conduct a comprehensive measurement broadband at 380 MHz 640 WHT. From measured data, extract model root- mean-square (RMS) delay spread shadow fading (SF) both line-of-sight (LoS) non-line-of-sight (NLoS) links. fitting results reveal that RMS spreads LoS NLoS conditons can be modeled as Lognormal...
The cyclic air braking strategy on the long steep downward slopes is one of main challenges to heavy haul train control in China. To overcome this dilemma, paper proposes an optimization method based approximate dynamic programming (ADP) algorithm which can achieve low maintenance costs and high running efficiency premise safe operation. problem described considering characteristics railways Then formalized as a Markov decision process (MDP) critical elements ADP methodology are introduced...
Accurately calculation of temperature can truly judge the output large capacity turbo generator. The copper and core loss generator is major factor to determine field. And resistance coils, an important variable for calculating loss, varies with windings temperature. It more obviously that interactions between in 1100MW nuclear power rotor axial-radial ventilation form, which because have high thermal coefficient imbalance this form. Thence, field calculated by finite volume method...
