In order to improve the accuracy of shield tunneling parameter matching under the limited data, the matching model based on support vector machine (SVM) and exponential adjustment inertia weight immune particle swarm optimization (EAIW-IPSO) is proposed.The nonlinear relationship model between the tunneling parameters and the ground settlement is c

Ultra-wideband (UWB) nonlinear frequency modulation (NLFM) waveforms have the advantages of low sidelobes and high resolution.By extending the frequency domain wideband synthesis method to the NLFM waveform, the synthetic bandwidth will be limited, and the grating lobe will grow as the number of subpulses increases at a fixed bo bichette cleats syn
Deslorelin is a synthetic GnRH analogue, which is being used as a contraceptive in animals by acting as a gonadal suppressant.The product Suprelorin (Virbac, Australia) contains deslorelin as a biocompatible, slow release subcutaneous implant.The continuous release of deslorelin provokes a down-regulation of GnRH receptors, and subsequently, inhibi
Aiming at the shortcomings of traditional radar identification based on artificial judgment and module matching, this paper proposes an intelligent identification algorithm based milwaukee 2485-22 on joint time-frequency.The radar radiation source signal is transformed by time-frequency, and the processed signal is input into the automatic encoder
