WebDecision field theory provides for a mathematical foundation leading to a dynamic, stochastic theory of decision behavior in an uncertain environment. This theory is used to explain (1) violations of stochastic dominance, (2) violations of strong stochastic transitivity, (3) violations of independence between alternatives, (4) serial position effects on … WebTownsend found that the current at first increased proportionately with the applied voltage and then remained nearly constant at a value i 0 which corresponded to the background …

In electromagnetism, the Townsend discharge or Townsend avalanche is a ionisation process for gases where free electrons are accelerated by an electric field, collide with gas molecules, and consequently free additional electrons. Those electrons are in turn accelerated and free additional electrons. The result is an … See more The avalanche occurs in a gaseous medium that can be ionised (such as air). The electric field and the mean free path of the electron must allow free electrons to acquire an energy level (velocity) that can cause impact … See more A Townsend discharge can be sustained only over a limited range of gas pressure and electric field intensity.
