When unpolarised light is reflected from a smooth dielectric surface, it is spontaneously partially polarised. This process applies to both specular and diffuse reflection, although the effect is greatest for specular reflection. This paper is concerned with exploiting this phenomenon by processing images of smooth dielectric objects to recover surface normals and hence height. The paper presen...

In this paper, we propose a method for cataract screening. Referring to the fact of increasing number of cataract especially for the people who lived in the developing countries, this kind of discussion will be important. The method used three kinds of features; specular reflection appearance, texture uniformity and average intensity inside the pupil. Actually, The core of our method is based o...

The effect of single and double-layer anti-reflective coatings on efficiency enhancement of silicon solar cells was investigated. The reflectance of different anti-reflection structures were calculated using the transfer matrix method and then to predict the performance of solar cells coated by these structures, the weighted average reflectance curves were used as an input of a PC1D simulation....

an experimental program was conducted to determine the effects of geosynthetic reinforcement on mitigating reflection cracking in asphalt overlays. the objectives of this study were to asses the effects of geosynthetics inclusion and its placement location on the accumulation of permanent deformation. to simulate an asphalt pavement overlaid on top of a crack in a concrete or asphalt pavement, ...

Quantum reflection of an atomic wave from a solid surface is caused by the attractive van der Waals force acting on the atom near the surface. The researchers had previously verified the quantum reflection of a cold neon atomic beam from a silicon surface. In this research they demonstrate the first known reflective atom-optical elements that use natural interaction of a solid surface, or attra...

Future middleware platforms will need to be more configurable in order to meet the demands of a wide variety of application domains. Furthermore, we believe that such platforms will also need to be reconfigurable, for example to enable systems to adapt to changes in the underlying systems infrastructure. A number of technologies are emerging to support this level of configurability and re-confi...
