A KERNEL METHOD BASED ON TOPIC MODEL FOR VERY HIGH SPATIAL RESOLUTION (VHSR) REMOTE SENSING IMAGE CLASSIFICATION [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 A kernel-based method for very high spatial resolution remote sensing image classification is proposed in this article. The new kernel method is based on spectral-spatial information and structure information as well, which is acquired from topic model,

Solution of an integral equation with a logarithmic kernel
International Journal of Mathematics and Mathematical Sciences, 1990 A simple independent integral equation technique is presented to solve an integral equation with a logarithmic kernel which governs solutions of many two-dimensional Dirichlet boundary value problems involving two coplanar and parallel infinite strips ...

Green’s Function for a Slice of the Korányi Ball in the Heisenberg Group Hn
International Journal of Mathematics and Mathematical Sciences, 2015 We give a representation formula for solution of the inhomogeneous Dirichlet problem on the upper half Korányi ball and for the slice of the Korányi ball in the Heisenberg group Hn by obtaining explicit expressions of Green-like kernel when the given ...

A priori estimates of global solutions of superlinear parabolic systems
Electronic Journal of Qualitative Theory of Differential Equations, 2016 We consider the parabolic system $ u_{t}-\Delta u = u^{r}v^{p}$, $v_{t}-\Delta v = u^{q}v^{s}$ in $\Omega\times(0,\infty)$, complemented by the homogeneous Dirichlet boundary conditions and the initial conditions $(u,v)(\cdot,0) = (u_{0},v_{0})$ in ...

Dirichlet Heat Kernel for the Laplacian in a Ball [PDF]
Potential Analysis, 2018 We provide sharp two-sided estimates on the Dirichlet heat kernel $k_1(t,x,y)$ for the Laplacian in a ball. The result accurately describes the exponential behaviour of the kernel for small times and significantly improves the qualitatively sharp results known so far.

A fundamental solution for the Laplace operator in a doubly connected domain
Bulletin of Computational Applied Mathematics, 2021 In this work, we find a harmonic Green function for a doubly connected domain using the theory of conformal mappings and then we define a Poisson kernel.

On an Asymptotic Property of Dirichlet Kernels
Известия Иркутского государственного университета: Серия "Математика"The main object of our study is the Dirichlet kernel. The properties of this trigonometric polynomial — the sum of cosines of multiple arcs — are of undoubted interest in the theory of trigonometric series.
