due to the complex structure of the pressure-adjusting device used in most sprinklersfor variable irrigation, it is not possible to observe the flow behavior of the water passingthrough the flow field. in this paper, an integral three dimensional (3d) numerical modelbased on the structural characteristics of the fluidic sprinkler was constructed to simulatethe flow field distribution using comp...

The relaxation of the field ionisation rate after depletion of a tungsten surface is studied for hydrogen and helium with a pulsed laser atom probe. The reduction of the field ion rate and its recovery to a steady state value within some milliseconds is due to a correlation between field ion rate and surface coverage. Three possible models are discussed for explaining the enhancement of the rat...

In these mostly expository lectures, we give an elementary introduction to conformal field theory in the context of probability theory and complex analysis. We consider statistical fields, and define Ward functionals in terms of their Lie derivatives. Based on this approach, we explain some equations of conformal field theory and outline their relation to SLE theory.
