One main geodetic objective of the European Space Agency’s satellite mission GOCE (gravity eld and steady-state ocean circulation explorer) is the contribution to global height system uni cation. This can be achieved by applying the Geodetic Boundary Value Problem (GBVP) approach. Thereby one estimates the unknown datum offsets between different height networks (datum zones) by comparing the ph...

This report presents our solution to the problem of processing continuous Nearest Neighbor (NN) queries for moving objects trajectories when the exact position of a given object at a particular time instant is not known, but is bounded by an uncertainty region. As has already been observed in the literature, the answers to continuous NN-queries in spatiotemporal settings are time parameterized ...

The objective of GOCE (Gravity Field and Steady-State Ocean Circulation Explorer) is the determination of the Earth’s gravity field with high spatial resolution. The main science sensor (the gradiometer) measures differential accelerations, from which the gravitational gradients, i.e. the matrix of the second derivatives of the gravitational potential, are derived. Some of them (the diagonal co...

Atom-interferometry gravity gradiometry has been developed as a promising technique for future gradiometric missions after GOCE due to its greater sensitivity in micro-gravity environments and constant performance over the measurement bandwidth. In this paper, feasible method of spaceborne atom-interferometry is proposed by utilizing free-fall condition cold atoms space. Compared with GOCE, whi...

Stem cells are cells with the ability to divide for indefinite periods and to give rise to specialized cells.  Stem cell therapy has now been emerged as an extraordinary promise to treat a wide range of diseases and conditions.  However, except blood stem cell transfer by bone marrow transplant which has been used as an standard practice for more than 50 years, nearly all of therapeutic potenti...
