Following the invention of the telegraph, electronic computer, and remote sensing, “big data” is bringing another revolution to weather prediction. As sensor and computer technologies advance, orders of magnitude bigger data are produced by new sensors and high-precision computer simulation or “big simulation.” Data assimilation (DA) is a key to numerical weather prediction (NWP) by integrating the...
This paper sets to research pointing at the threat of microwave weapons when the armed police officers and soldiers encounter in dealing with contingencies and maintaining the stability, and also discusses the shielding effectiveness of electromagnetic shielding fabric. With mental shield as the research object, use the genetic algorithm optimization principle and the HOBBIES software to simulate...
In order to ensure the electricity output quality of one turbocharged diesel generator set under pulsed load, some measures were taken to control the speed regulating rate of original power machine. One main reason causing the big diesel speed regulating rate in experiment is the lack of air for combustion in the early period of pulse. The other reason is that the energy stored by set shafting parts...
