The southeastern Tibetan Plateau has been deeply dissected by major rivers and their tributaries into high-relief topography with deep gorges. In this region, most hillslope gradients in the areas approach a threshold value, landslides are dominant surface erosion process. For work, we analyzed process determining excess from hillslope. Slope analysis found similar normal distribution of slope ...

Surface topography is an efficient tool for the understanding of physical phenomena, especially if multiscale roughness analysis performed. However, observable scale range in a measured with 3D optical profilometers quite limited. Therefore, all scales linked to phenomenon might not be measured, which impedes correct surface. Stitching topographies, technique combining elementary topographic ma...

The X-ray topography station and attached beam line 4W1A are part of the Beijing Synchrotron Radiation Facility (BSRF) to employ the bright synchrotron radiation from the Beijing Electron Positron Collider (BEPC). The main purposes of the station are used for the study of the perfection of single crystals, high resolution multi-crystals diffraction and Xray standing wave research. The intense p...

Coating characteristics such as composition, crystallite features and topography collectively impact the cell response. The influence from splats has not yet been assessed for hydroxyapatite (HAp) thermal spray coatings. The objective of this work is to (a) survey the topography on commercial implants, (b) ascertain topography formation from single splats, and (c) determine the osteoclast resor...

Catchment drainage area is a basic spatial unit in landscape hydrology within which the authorities estimate water balance and manage resources. The catchment commonly delineated based on surface topography, determined using digital elevation model. Therefore, only flow over implicitly considered. However, substantial portion of rainfall infiltrates percolates through soil profile to groundwate...

Custom Spectral Domain Optical Coherence Tomography (SD-OCT) provided with automatic quantification and distortion correction algorithms was used to measure anterior and posterior crystalline lens surface elevation in accommodating eyes and to evaluate relationships between anterior segment surfaces. Nine young eyes were measured at different accommodative demands. Anterior and posterior lens r...

Introduction The aim of hydrography is basically to chart the underwater topography. A precise knowledge of the sea-bottom features has great relevance mainly in shallow waters, where navigational safety must be assured at any cost. Ideally, one should have available a complete series of maps of the sea-bottom topography. approximately 100 km x 100 km. Although the basic information provided by...

Abstract The self organizingmap SOM of Kohonen is one of the most successful models of unsupervised learning Its popularity is partially due to the visualization topography preservation of relations among clusters in high dimensional input space SOM learns slowly especially in the initial phase and the preservation of topography by SOM maps is not based on any quantitative criteria We have obta...

Abstract. An information diagnostic system is currently being developed. The system is based on electromagnetic non-destructive testing and uses a matrix magnetic converter for revealing flaws and forecasting the reliability of machines and mechanisms. The considered algorithm, which analyses magnetic nondestructive testing results, uses a dynamic type matrix magnetic transducer. To estimate cr...
