A unified approach to split absorbing boundary conditions for nonlinear Schr\"{o}dinger equations
An efficient method is proposed for numerical solutions of nonlinear
Schr\"{o}dinger equations in an unbounded domain. Through approximating the
kinetic energy term by a one-way equation and uniting it with the potential
energy equation, absorbing boundary conditions are designed to truncate the
unbounded domain, which are in nonlinear form and can perfectly absorb the
waves outgoing from the truncated domain. We examine the stability of the
induced initial boundary value problems defined on the computational domain
with the boundary conditions by a normal mode analysis. Numerical examples are
given to illustrate the stable and tractable advantages of the method.Comment: 17 pages, 6 figures, 40 conference

OPTICAL REMOTE SENSING IMAGE OPTIMIZED DEHAZING ALGORITHM BASED ON HOT
Due to the significantly effect of clouds in the near-earth space environment to remote sensing satellite images, some satellite images
can not be utilized normally, resulting in large limitation of their application fields. For the background suppressed haze thickness
index (BSHTI) and improvement background suppressed haze thickness index (IBSHTI) have the characteristics of thoroughly cloud
correction and badly deficiency of the tone and texture information, we propose to first adopt IBSHTI to calculate the cloud
thickness image of different bands, then the dark-pixel images are obtained by down sampling, and the texture is eliminated by
introducing Texture and edge information (TEI). Experiment results show that our method can well retain the ground tone and
texture information while removing the effect of clouds, especially in urban areas
