The coastal area is a multi-issue area and its observation provides heterogeneous geographical database. Challenges are located on the integration and the rendering of these data: (1) geographic data used to characterize the sea must be combined to obtain water depth and sea/land interface (data heterogeneity problem) and (2) current visualization systems do not provide continuous rendering on ...

Mixing between two different fluids with a mutual interface must be initiated by fluid transporting across this fluid interface, caused, for example, by applying an unsteady velocity agitation. In general, there is no necessity for this physical flow barrier between the fluids to be associated with extremal or exponential attraction, as might be revealed by applying Lagrangian coherent structur...

We demonstrate a new method for electrical manipulation of nuclear spins utilizing dynamic nuclear polarization induced by quantum Hall effect breakdown. Nuclear spins are polarized and detected through the hyperfine interaction between a nuclear spin system and a two-dimensional electron system located at an interface of GaAs/AlGaAs single heterostructure. Coherent oscillations between the nuc...

Estimating the costs of software development is one of the most important activities in software project management. Inaccuracies in such estimates may cause irreparable loss. A low estimate of the cost of projects will result in failure on delivery on time and indicates the inefficiency of the software development team. On the other hand, high estimates of resources and costs for a project wil...

In this paper propagation of combined laser beam through atmosphere is investigated. Laser beam is combined via lens array arrangement. Turbulence is considered as an affecting factor of atmosphere and its effects on transverse coherence length (Fried parameter), peak intensity, propagation efficiency, and spot size of the laser beam is investigated. Coherent and incoherent combined beam are co...
