Complex shapes - such as the surface of the human brain - may be represented and analyzed in frequency space by means of a spherical harmonics transformation. A key step of the processing chain is introducing a suitable parametrization of the triangular mesh representing the brain surface. This problem corresponds to mapping a surface of topological genus zero on a unit sphere. An algorithm is ...

We present a new method to transform the spectral pixel information of a micrograph into an affine geometric description, which allows us to analyze the morphology of granular materials. We use spectral and pulse-coupled neural network based segmentation techniques to generate blobs, and a newly developed algorithm to extract dilated contours. A constrained Delaunay tesselation of the contour p...

Here, we here present scanning electron microscope data for the existent telocytes (TCs) on the endothelial surface of the wall of pig coronary arteries, internal thoracic arteries and carotid arteries. These cells have a small (8.39 ± 1.97 μm/4.95 ± 0.91 μm) cell body of different shapes (from round to triangular, depending on the number of cellular prolongations) with very long (of about 30 μ...

The construction of a smooth surface from an irregular mesh in space is considered. The mesh vertices can either be interpolated or approximated as a control net. A collection of triangular B6zier patches results from a local, affine invariant and visually smooth interpolation scheme that can represent surfaces of arbitrary topological type. It is based on a domain 4-split. Beside the surface c...

This paper presents a design of triangular wide slot antenna with same shaped patch which is fed by CPW. Patch is working as a radiating element and wide slot working as a ground. Detail simulation is conducted to understand its behaviour and optimize for broad band operation. The results are analysed and discussed in terms of return loss, VSWR, Gain, current distribution etc. The result shows ...

We develop a model to study the locomotion of snakes on inclined planes. We determine numerically which snake motions are optimal for two retrograde traveling-wave body shapes, triangular and sinusoidal waves, across a wide range of frictional parameters and incline angles. In the regime of large transverse friction coefficients, we find power-law scalings for the optimal wave amplitudes and co...

Development effort on Autonomous mobile robots that can operate in unknown environments are ongoing order to extend the application area of robots. In navigate, an autonomous robot needs a map environment and location information relative map. Simultaneous Localization Mapping (SLAM) is prediction process which use this determine its position while building consistent The purpose study examine ...

This paper is presented to develop the hydrodynamic performance of double-row floating breakwater (FBW) by changing cross-sectional geometry in high wave periods. The ANSYS-AQWA software employed for present calculations, which a potential-based boundary element method (BEM). rectangular moored pontoons single- and types are selected, results transmission coefficient response amplitude operator...
