The spectral features of hyperspectral images, such as the spectrum at each pixel or the abundance maps of the endmembers, describe the material attributes of the structures. However, the spectrum on each pixel, which usually has hundreds of spectral bands, is redundant for classification task. In this paper, we firstly use spectral unmixing to reduce the dimensionality of the hyperspectal data...

Map Generalization is the process by which coarse scale maps are to be derived from fine scale maps, balancing the amount of real-world information with visual confusion. This requires the use of operations such as simplification, selection, displacement and amalgamation of features that are performed subsequent to scale change. Map schematization can be regarded as a specific type of map gener...

To better understand protein-solvent interaction we have analyzed a variety of physical and geometrical properties of the solvent-excluded surfaces (SESs) over a large set of soluble proteins with crystal structures. We discover that all have net negative surface charges and permanent electric dipoles. Moreover both SES area and surface charge as well as several physical and geometrical propert...

We extend the results of a work by L. Hörmander [9] concerning the resolution of the characteristic Cauchy problem for second order wave equations with regular first order potentials. The geometrical background of this work was a spatially compact spacetime with smooth metric. The initial data surface was spacelike or null at each point and merely Lipschitz. We lower the regularity hypotheses o...

When humans look at a complex and ambiguous figure, they divide it into several elemental figures. This human visual characteristic is called figure segiegation. There is a problem when constructing a cognitive model for figure segiegation. That is, one interpretation is selected by most people for some figures, and several interpretations are selected almost equally for other figures. This pap...

A computer program in FORTRAN language is written to interpret the source parameters for the magnetic anomalies over tabular bodies. Sheet, dike and vertical step models are used in this program. The program is written for the magnetic interpretation method published in Exploration Geophysics, (2009). The method is based on the characteristic positions of the magnetic anomaly profile for determ...

We present a Brownian dynamics simulation study of static and dynamic properties of quasi-two-dimensional dispersions of colloidal spheres interacting by long-range screened electrostatic and by dipolar magnetic forces, respectively. The calculated van Hove real-space dynamic correlation functions, mean squared displacements, and hydrodynamic functions are shown to obey a dynamic scaling behavi...
