چکیده
The Auvergne test on quasi-geoid estimation has been set up in co-operation with IGN and EGGP. IGN supplied the gravity, DTM and GPS/levelling data while EGGP contributed in assessing the test procedures. A first comparison between the computations performed by six different groups have been presented during the last Hotine-Marussi Symposium held in Rome (July 5-9, 2009). The results of this test proved the substantial equivalence of the applied computation methods.

Determination of the geoid with a high accuracy is the main task among researchers in the geodetic community. Precise determination of a regional geoid is usually carried out combining a global geopotential model data with a set of point or mean terrestrial gravity anomalies measured in the region and some topographic information. In this research a primary Iranian gravimetric geoid model has b...
متن کاملExperimental evidence for the evolution of indirect genetic effects: changes in the interaction effect coefficient, psi (Psi), due to sexual selection.
Indirect genetics effects (IGEs)--when the genotype of one individual affects the phenotypic expression of a trait in another--may alter evolutionary trajectories beyond that predicted by standard quantitative genetic theory as a consequence of genotypic evolution of the social environment. For IGEs to occur, the trait of interest must respond to one or more indicator traits in interacting cons...

International competition is dictating the need for increased levels of information integration in manufacturing industry, whereby the responsiveness and efficiency of systems can be advanced. This article outlines the relative roles of various standards and initiatives (including MAPROP, IGES, PDESISTEP and EDIF) and associated major research programmes aimed at facilitating manufacturing syst...
متن کاملPMD IVS Analysis Center
The main activities carried out at the PMD (Politecnico di Milano DIIAR) IVS Analysis Center during 2012 are briefly higlighted, and future plans for 2013 are sketched out. We principally continued to process European VLBI sessions using different approaches to evaluate possible differences due to various processing choices. Then VLBI solutions were also compared to the GPS ones as well as the ...
متن کاملInvestigation of the Efficiency of Multi-purpose Gravity Network of NCC to Precise Geoid Determination, Case Study: Northwest Area of Iran
The national height system of Iran, orthomertic height, is referred to geoid as the vertical datum. Consequently, the geoid has many important applications in engineering. The slow, laborious and expensive orthomertic heights can be obtained in sufficient accuracy level from geodetic height (derived by GNSS observations) and a precise geoidal height. Over the past two decades, the gravity divis...
