The aim of this article is to characterize the penetration bias of the ENVIronmental SATellite (ENVISAT) radar altimeter over the Antarctic ice sheet through comparison with the more accurate measurements of the Ice, Cloud and land Elevation Satellite (ICESat) altimeter at crossover points. We studied the difference between ENVISAT and ICESat fluctuations over six years. We observed the same pa...

Residual stresses of physical vapor deposition (PVD) hard coatings can be measured using X-ray diffraction (XRD) methods under either conventional d-sin2 ψ mode or glancing incident (GIXRD) mode, in which substantial uncertainties exist depending on the applied diffraction parameters. This paper reports systematic research on the effect of the two analytical modes, as well as the anisotropic el...

This exploratory paper attempts to describe the status of the international digital divide in the Mediterranean area. To do so, it has assembled data on the level of Internet penetration in the Union for the Mediterranean (UM), Some non-littoral UM states were included for purposes of comparison, as were a number of EU non-UM states. Finally, a small number of non UM, non EU, OECD members were ...

In this study we explore the global effect of the Internet on democracy over the period of 1992 to 2002 by observing the relationships between measures related to democracy and Internet prevalence. Our results show a significant correlation between Internet penetration (measured as the estimated number of Internet users per 1,000 people) and a common indicator of a nation’s level of democratiza...

creep compliance is one of the fundamental tests of mechanistic- empirical flexible pavement design procedure in the aashto 2002 design guide. in this research, a new artificial neural network model for estimating the hma creep compliance with the generalization ability of r=0.949 has been developed successfully using feed forward multi layer perceptron artificial neural networks (anns) with le...

This study investigated fifteen structural factors influencing B2C e-commerce penetration across country contexts. Data collected from secondary sources on a sample of 20 countries showed that depends country’s network readiness, institutional structures such as ICT laws, supply side labour skills, credit card penetration, per capita GDP and proportion citizens online. Factors related to transp...
