—Recently the developments of Ubiquitous Computing and Augmented Reality technologies have made many changes on the existing applications. However, the contents used in the applications have been not revised conceptually. Thus, an expansive representation of the contents is required to adapt resources to new computing environments, and to reflect new emerging features such as realism, mobility ...

Explicit analysical expression is derived for mixing matrix of three neutrions in matter using a set of direct vacuum physical parameters. Results are presented in simple, symmetrical form. The physical contents are more clear than using of tradtional mixing angles. There is no problem about mixing orders.

The Earth is a big place: its radius is about 6400 km. In comparison, the deepest boreholes drilled are about 10 km deep. We thus have little opportunity to take direct measurements or samples inside the Earth: it is mostly inaccessible. And even for the upper 10 km that we can sample, the cost of drilling deep boreholes is very high. This means that inferences about the Earth’s interior are la...
