Review of heat and water movement in ®eld soils

Coupled heat and water transport in soils has enjoyed extensive focus in soil physics and hydrology and yet, until recently, there has never been a satisfactory comparison of water vapor ̄uxes measured in the ®eld with theory. At least two factors have led to this, ®rst, most of the experimental work has been laboratory oriented with steady state boundary conditions imposed and second, there ha...

Longest Path in Networks of Queues in the Steady-State

Due to the importance of longest path analysis in networks of queues, we develop an analytical method for computing the steady-state distribution function of longest path in acyclic networks of queues. We assume the network consists of a number of queuing systems and each one has either one or infinite servers. The distribution function of service time is assumed to be exponential or Erlang. Fu...

Physics of plasma control towards steady-state operation of ITER

ITER is a fusion experimental reactor to show scientific and technological feasibility of fusion energy. It is designed to produce fusion power of 500MW for 300-500 seconds with fusion energy gain Q at least 10 (Q ≥10) [1], [2]. ITER should show scientific and technological feasibility of fusion energy as one step to DEMO, which produces electricity by fusion energy. Although design of DEMO wil...

Transient and steady-state response properties of movement detectors.

The transient and steady-state responses of movement detectors are studied at various pattern contrasts (i) by intracellularly recording from an identified movement-sensitive interneuron in the fly's brain and (ii) by comparing these results with computer simulations of an array of movement detectors of the correlation type. At the onset of stimulus motion, the membrane potential oscillates wit...
