Due to the complexity of internal structure natural coal and its characteristic multicomponent, depth methane adsorption potential well is nonuniform, which makes it difficult accurately evaluate capacity coal. Besides, in order find out factors affecting distribution wells coal, this paper calculated number during according Langmuir kinetics process. Coal samples with different metamorphic deg...

Removing camera motion blur from a single light field is a challenging task since it is highly ill-posed inverse problem. The problem becomes even worse when blur kernel varies spatially due to scene depth variation and high-order camera motion. In this paper, we propose a novel algorithm to estimate all blur model variables jointly, including latent sub-aperture image, camera motion, and scene...

We consider the inverse scattering problem of reconstructing multiple impenetrable bodies embedded in an unbounded, homogeneous and isotropic elastic medium. The inverse problem is nonlinear and ill-posed. Our study is conducted in an extremely general and practical setting: the number of scatterers is unknown in advance; and each scatterer could be either a rigid body or a cavity which is not ...

Exact structure from motion is an ill-posed computation and therefore very sensitive to noise. In this work I describe how a qualitative shape representation, based on the sign of the Gaussian curvature, can be computed directly from motion disparities, without the computation of an exact depth map or the directions of surface normals. I show that humans can judge the curvature sense of three p...

We propose a solution to the problem of inferring the depth map, radiance and motion field of a scene from a collection of motion-blurred and defocused images. We model motion-blurred and defocused images as the solution of an anisotropic diffusion equation, whose initial conditions depend on the radiance and whose diffusion tensor encodes the shape of the scene, the motion field and the optics...

groundwaters hydrochemistry of ayrakan and cheshmeh shotori areas and geochemistry of rare earth elements, indicate ayrakan alkali granite as the origin of uranium and other dissolved elements in groundwaters of these areas. geochemical and hydrogeochemical studies as well as the trend of uranium and thorium transition and mobility in aqueous environments of these areas indicate uranium adsorpt...
