...the surfaces intersected are well separated along all intersection curves. For transversal intersections the divide and conquer strategy of recursive subdivision, Sinha's theorem [2] and the convex hull property of NonUniform Rational B-Spline surfaces (NURBS) efficiently identify all intersection branches...
...transform infrared spectroscopy (FT-IR), atomic force microscopy (AFM), transmission electron spectroscopy (TEM), X-ray photoelectron spectroscopy (XPS) and white light interferometry (WLI). The degree of surface substitution (DSS) was determined using Si concentrations from XPS survey scans, as well as deconvoluted...
Synopsis: The paper is a review of principle and performance of latex modified mortars.When latex (i.e. a polymer dispersion in water) is added to a cement based mortar, the polymer particles will partly adhere to the cement grains and improve the rheology, and after setting when liquid water is reduced...
...coastal sea transportation industry in Norway. Historical developments in the Norwegian maritime industry are compared and discussed in relation to changes in long-haul road transportation and aviation. To set the stage for a discussion of potential safety implications, we consider regulatory challenges associated...
...materials and their derivative products, can play an important role in the global shift to more sustainable production methods and ecological economic systems. The concept of cluster, however, is difficult to define and study. In this paper, we present quantitative methods based on Input-output and in Operations...
...conductivity of volcanic ash and pumice collected from Kamchatka, Far East of Russia, and from Iceland, in dependence on different humidity and density. The research shows that the humidity of the samples is the key factor for thermal conductivity, both in the frozen and thawed state. And this in turn depends...
