Fractional Galilei invariant advection–diffusion (GIADE) equation, along with its more general version that is the GIADE equation nonlinear source term, discretized by coupling weighted and shifted Grünwald difference approximation formulae Crank–Nicolson technique. The new of backward substitution method, a well-established class meshfree methods, proposed for numerical consequent equation. In present approach, final given summation radial basis functions, primary approximation, related...

Underwater datasets usually have blurred objects, low contrast, and color distortion, which seriously restrict the performance of target detector on it. It is very important to use data enhancement methods improve original dataset. In this paper 7 detection models are trained Trash-ICRA19 underwater datasets, namely Faster-RCNN, SSD, YOLO V1-V5. Through comparison, it found that YOLOV5 has best with 79.7 AP 138.89 FPS. Then three about adopted UDD Dark Channel Prior(UDCP), Contrast-Limited...

In this paper, a singularly perturbed convection–diffusion equation is studied. At first, the original problem transformed into parameterized Volterra integro-differential by using an integral transform. Then, second-order finite difference method on arbitrary mesh given. The stability and local truncation error estimates of discrete schemes are analyzed. Based equidistribution principle estimation, adaptive grid algorithm addition, in order to calculate parameters transformation equation,...
