In this study, the effect of the substrate roughness on adhesion of mushroom-shaped microstructure was experimentally investigated. To do so, 12 substrates having different isotropic roughness were prepared from the same material by replicating topography of different surfaces. The pull-off forces generated by mushroom-shaped microstructure in contact with the tested substrates were measured an...

Intracranial aneurysms with poor topography are still difficult and dangerous to be catheterized during endovascular procedures. Here we report a novel coil guiding catheterization technique which could safe helpful. Seven of 5 cases were embolized the in Zhongshan Hospital, Fudan University, from January 2017 March 2019. All for embolization. One was posterior communicating segment internal ca...

In 2002, the maturity of grapevine was researched on the basis of sugar content, total titratable acidity and pH at seven locations with an undulating topography in four varieties 'Chardonnay', 'Riesling', 'Welschriesling' and 'Sauvignon'. All sampling points were geo-referenced simultaneously with DGPS for creating sugar maps. The significant relationship between the varying altitude above sea...

Abstract Groundwater demand has increased due to overpopulation and intensive irrigation which resulted in decline of water resources deterioration quality. In this view, a microlevel study was conducted through hydrogeochemical investigation resistivity survey (VES) Kalanad river basin, Kasaragod, Kerala. The aims determine the spatial variations physicochemical parameters with delineation geo...

Altimetry is probably one of the most powerful tools for ice sheet observation. Our vision of the Antarctic ice sheet has been deeply transformed since the launch of the ERS1 satellite in 1991. With the launch of ERS2 and Envisat, the series of altimetric observations now provides 19 years of continuous and homogeneous observations that allow monitoring of the shape and volume of ice sheets. Th...

A physically-based model to correct atmospheric and topographically induced illumination effects in optical satellite data is developed and tested. Special emphasis is put on the impact of rugged terrain. Ground reference data for various land use classes enables the assessment of the corrections' influence on land use classifications. The estimation of surface reflectance is achieved in a two-...

A simple, efficient CAD-oriented equivalent circuit modeling approach of frequency-dependent behavior of substrate noise coupling is presented. It is shown that the substrate exhibits significant frequency-dependent characteristics for high frequency applications using epitaxial layers on a highly doped substrate. Using the proposed modeling approach, circuit topographies consisting of only ide...

Particulate contamination deposited on silicon wafers is typically the dominant reason for yield loss in VLSI manufacturing. The transformation of contaminating particles into defects and then electrical faults is a very complex process which depends on the defect location, size, material, and the underlying IC topography. An efficient defect macromodeling methodology based on the rigorous two-...

Dispersive effects induced by weak hydrostatic imbalance in the presence of topography and stratification are incorporated into a new model of barotropic (vertically integrated) mesoscale ocean dynamics. This barotropic model is obtained by first expanding the solutions of three dimensional Euler-Boussinesq equations in a regular perturbation expansion in terms of the several small dimensionles...

[1] Changes in gravity due to volcanic loading of the crust are influenced by topography. We investigate the relative importance of topography and self-gravitation in the interpretation of gravity changes. It is shown that modeling of gravity changes can be more precise with the introduction of topographic relief, although it is neglected self-gravitation of the medium. This paper exploits this...
