Based on the derived representation of indicator function, we design improved direct sampling methods by applying incident fields with multiple directions and multiple frequencies.
The polar crust is unusually thin, and the new eruptions may allow unusually direct sampling of mantle rock -- a holy grail of science.
For example, a large ore body may extend for great distances underground in three dimensions, but mineralogical clues can direct sampling for the mapping effort.
Direct sampling of the stratosphere has shown that the major haze-forming agent from volcanic eruptions is not fine dust but an aerosol of tiny sulfuric acid droplets.
Example of direct sampling of air.
Direct sampling from this distribution is not feasible.
Then, we performed a bivariate reconstruction with the recently developed Direct Sampling software.
The computational cost of the new scheme shows significant gains over direct sampling.
Direct sampling of the Earth's deepest regions, including the core, is impossible.
A transform method was used to model a discrete time multi-tap direct sampling mixer.
Two Monte Carlo based simulations were applied, direct sampling and latin hypercube sampling.
