The geodetic point fields play a crucial role in measuring a terrain, in surveying, and mapping applications. Due to the rapid development in the domain of information technologies, it makes sense to consider using the database and web technologies to manage and disseminate the...

The lithospheric structure beneath the Indian Ocean is probably the most complicated, but at the same time, the least understood among world’s oceans. Results of tomographic, geochemical, magnetic and other surveys provide the evidence of its complex geological history. Seismic surveys have&...

Objective of this paper is regional gravity field modelling of the Earth combining surface gravity disturbances and satellite gravity gradiometry (SGG) data based on the least-squares collocation (LSC) over the void areas in Iran, where the existing gravity data are not intensified or&#...

It is proved that a 2-connected claw-free graph admits a spanning Eulerian subgraph if it is N_{1,1,4} or N_{1,2,2} or Z_5 or P_8-free. Related hamiltonicity results are also obtained.
