Gibbs oscillations in the truncated spectral representation of the earth's topography are strongly reduced by determining its spectral coefficients as a minimum of a nonuniformly weighted, nonquadratic cost function. The cost function penalizes the difference between spectral and true topography with weights that are explicit functions of the topographic height and its gradient. The sensitivity...

Background Scoliosis patients typically undergo numerous spinal radiographs and exposed to relatively high doses of ionizing radiation. This has raised concern regarding the effects of this repeated exposure. Additionally assessment of spinal deformities using surface topography of the back is currently considered essential. Digital Photogrammetry can contribute in non-invasive measurements of ...

We create a novel data set on the European river network and for ruggedness of trade routes between countries integrate these new indicators into recently developed structural gravity models. Moreover, we propose approach how to differentiate contemporaneous historical costs. Applying two-stage estimations, assess impact topography by combining worldwide, European, domestic data. While border e...

Using Molecular Mechanics and Molecular Dynamics methods, we investigated at the atomistic level the topography effects both on physisorption on different crystalline planes of TiO2 anatase and on the competitive adsorption when three different crystallographic faces were simultaneously present in an idealized nanosized crystal interacting with a simple heteroaromatic molecule experimentally us...

in this work the effects of various methods of agitation on the properties of electroless ni-p-mos2 composite coatings were investigated. magnetic stirring as well as purging the solution with gas (air, oxygen, nitrogen) were used. plating rate, chemical composition, mos2 distribution, and hardness of the deposit were measured. topography of coating was studied with metallography and scanning e...

Article history: Received 12 January 2016 Received in revised form 26 May 2016 Accepted 27 May 2016 Available online 31 May 2016 A fundamental scientific question is, what controls the Earth's topography? Although the theoretical principles of isostasy, flexure, and dynamic topography arewidely discussed, the parameters needed to apply these principles are frequently not available. Isostatic fa...

The aim of this study is to explain topography induced spatial variations in the diurnal cycles of assimilation and latent heat of Mediterranean forest. Spatial variations of the fluxes are caused by variations in weather conditions and in vegetation characteristics. Weather conditions reflect short-term effects of climate, whereas vegetation characteristics, through adaptation and acclimation,...
