Determining the language proficiency level required to understand a given text is a key requirement in vetting documents for use in second language learning. In this work, we describe our approach for developing an automatic text analytic to estimate the text difficulty level using the Interagency Language Roundtable (ILR) proficiency scale. The approach we take is to use machine translation to...

The numerical simulation of tropical cyclones has been increasingly conducted using the advanced Weather Research and Forecast (WRF) model with large-eddy (LES) technique. Given importance boundary wind profile for vertical exchange horizontal momentum between atmosphere ocean, drag coefficient was evaluated in WRF-LES framework at finest grid spacing 37 m. In absence TC–ocean interaction, deri...

There are three popular methods to understand the land subsidence: leveling, Global Navigation Satellite System, and Interferometric Synthetic Aperture Radar (InSAR) analysis using SAR images. While both leveling System can measure amount of subsidence only at specific points, InSAR observe a wide area in short time intervals. In terms accuracy, however, is inferior leveling; centimeter/millime...

The purpose of this research paper is to study the tool wear and surface roughness of AISI 8620 material using coated ceramic tool by turning process. Ceramic cutting tools have outstanding material hardness, resistance to high temperatures, wear resistance, chemical stability and hot hardness. Ceramic tool with Al2O3 + TiC (golden) coating was used to investigate the surface roughness and tool...

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...

The high-precision unification of global height datum has long been a hot issue in the field geodesy. chronometric leveling method originates from gravitational redshift effect general relativity, which may provide new solution for datum. difference between two locations could be measured via frequency comparison optical clocks. We build error model leveling, mainly including measurement system...
