Scattered Enhancement

Enhancement in Data Mining Technique for Scattered Document Using Clustering

Clustering is a widely studied data mining problem in the text documents. The problem finds numerous applications in customer segmentation, classification, collaborative filtering, visualization, document organization, and indexing. In this paper, we will provide a detailed survey of the problem of text clustering. We will study the key challenges of the clustering problem, as it applies to the...

Chiral optical fields: a unified formulation of helicity scattered from particles and dichroism enhancement.

We establish a general unified formulation which, using the optical theorem of electromagnetic helicity, shows that dichorism is a phenomenon arising in any scattering-or diffraction-process, elastic or not, of chiral electromagnetic fields by objects either chiral or achiral. It is shown how this approach paves the way to overcoming well-known limitations of standard circular dichroism, like i...

Backscattering enhancement of an electromagnetic wave scattered by two-dimensional rough layers.

The problem of an electromagnetic wave scattered by a slab with two rough boundaries is solved by the small-perturbation method under the Rayleigh hypothesis. To obtain the perturbative development, we use a systematic procedure that involves integral equations called the reduced Rayleigh equations. Then we show for a dielectric slab deposited on a silver film that the backscattering enhancemen...

Image Warping with Scattered

Image warping has many applications in art as well as in image processing. Usually, displacements are computed with mathematical functions or by transformations of a triangulation of control points. Here, di erent approaches based on scattered data interpolation methods are presented. These methods provide smooth deformations with easily controllable behavior. The usefulness and performance of ...
