Several possible approaches for airborne vector gravimetry are compared using the spectral analysis technique. The equations reduced to a time-invariant form special averaging method. Then Fourier transform is applied equations. accuracy of each approach determined as power density gravity Wiener estimate error. Numerical results presented given priori stochastic models disturbance and measurem...

gravity acceleration data have grand pursuit for marine applications. due to environmental effects, marine gravity observations always hold a high noise level. in this paper, we propose an approach to produce marine gravity data using satellite altimetry, high-resolution geopotential models and harmonic splines. on the one hand, harmonic spline functions have great capability for local gravity ...

Abstract The paper describes a new methodology for postprocessing raw data from strapdown airborne gravimeter based on navigation-grade inertial measuring unit and global navigation satellite system receivers (one is board the aircraft others are placed ground). key aspects of methodology’s algorithms outlined. We also present numerical results (gravity estimates) two gravimetry surveys. survey...

This article contains the dataset referring to the article "Study of the effect of the dispersion of functionalized nanoparticles TiO2 with photocatalytic activity in LDPE" (Jahell et al., 2016) [1]. It includes the FT-IR data of the functionalized nanoparticles of TiO2 with Hexadecyltrimethoxysilane in different degrees of functionalization, thermogravimetric analysis, distribution and particl...

Several methods for checking the purity of nicotine used to calibrate analytical methods have been suggested since the 1920's. At that time the gravimetric method using picric acid was considered the most specific method while that employing tungstosilicic acid was considered most sensitive. However, neither method could be considered completely specific. Since the 1960's, the most commonly use...
