determination of the thickness of a mountains glacier like alamkooh is very difficult due to its extremely cold climate conditions and high elevation, risk of falling large snow segments or balls and coarse topography of the glacier. in this research, due to the transparency of ice for electromagnetic (em) waves, and also, that ground penetrating radar (gpr) method is non-destructive, fast and ...

The known models of recent vertical movements of the Earth crust surface in the area of Poland were processed in the form of contour line map on the basis of the data of the first and second class geometric state levelling network. Second map done by Wyrzykowski (1985) was based on the results of measurements made in 1871-1882, 1926-1937, 1952-1956 and 1975-1977. The newest results of assignmen...

background: dielectric barrier discharge (dbd), a source of non-thermal plasma, is used in surface decontamination. objective: to study the effect of dbd plasma treatment, we evaluated the effect of plasma exposure time on inactivation of bacillus subtilis. results: applying the dbd plasma to the culture of b. subtilis caused complete sterilization of the surface without any thermal effects. in...

SRTM/DTM2006.0 residual terrain model data to improve quasigeoid computations in mountainous areas devoid of gravity data, Journal of Geodesy 84(9): 557-567. Abstract: A global geopotential model, like EGM2008, is not capable of representing the high-frequency components of Earth's gravity field. This is known as the omission error. In mountainous terrain, omission errors in EGM2008, even when ...

We have developed a new theory for correcting track irregularities by applying their restored waveforms and carried out experimental levelling and lining work. In this theory, the optimum shifting/lifting values are obtained as solutions for a typical quadratic programming problem. Restrictions on shifting rails are formulated as constraint conditions of the optimization problem. Furthermore, i...
