A Target Recognition Algorithm in Remote Sensing Images
In the remote sensing image, the background is complex, which results in the low detection rate and slow speed of some target recognition algorithms. Therefore, an improved RFB Net model is used in this paper....

Open AccessInvariant tori of full dimension for higher-dimensional beam equations with almost-periodic forcing
In this paper, we focus on the class of almost-periodically forced higher-dimensional beam equations utt+(−Δ+μ)2u+ψ(ωt)u=0,μ>0,t∈R,x∈Rd,$$ u_{tt}+(-\Delta +\mu )^{2}u+\psi (\omega t)u=0,\quad \mu >0, t \in \mathb...

Open AccessReducibility of beam equations in higher-dimensional spaces
In this paper, we reduce a linear d-dimensional beam equation with an x-periodic and t-quasi-periodic potential for most values of the frequency vector via the KAM theorem. We focus on the measure estimates of sm...
