Assessment of EGM2008 over Britain using vertical deflections, and problems with historical data

Assessment of EGM2008 in Europe using accurate astrogeodetic vertical deflections and omission error estimates from SRTM/DTM2006

Evaluation of the first GOCE static gravity field models using terrestrial gravity, vertical deflections and EGM2008 quasigeoid heights

Recently, four global geopotential models (GGMs) were computed and released based on the first two months of data collected by the GOCE (Gravity field and steady-state Ocean Circulation Explorer) dedicated satellite gravity field mission. Given that GOCE is a technologically complex mission and different processing strategies were applied to real space-collected GOCE data for the first time, ev...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

The Use and Abuse of Vertical Deflections

This paper reviews the deflection of the vertical and its use and abuse in geodetic surveying. ‘Importantly, the deflection of the vertical in Australia will change by around 6” upon the implementation of the Geocentric Datum of Australia (GDA94). Therefore, for some applications, the deflection of the vertical may no longer simply be neglected in survey computations and adjustments. With the r...

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
