Fluctuation Theory of Luminance and Chromaticity Discrimination*
Journal of the Optical Society of America, 1963An attempt has been made to describe brightness and color discrimination in the framework of a fluctuation theory. The fluctuation theory states that a difference between two stimuli will be just noticeable if it exceeds, by some factor, the average of the fluctuations in the stimuli. If the statistical fluctuations in the number of quanta absorbed are

Fluctuation Theory for the Ehrenfest urn
Advances in Applied Probability, 1991The Ehrenfest urn model withdballs, or alternatively random walk on the unit cube inddimensions, is considered in discrete and continuous time, together with related models. Attention is focused on the fluctuation theory of the model—behaviour on unusual states—and in particular on first passage to the opposite vertex.

Nonequilibrium Theory of Fluid Fluctuations
The Physics of Fluids, 1970A generalization of previously existing theories of fluctuations in dilute monotonic gases is obtained which describes nonequilibrium states with spatial gradients. A kinetic description of the fluctuations is first derived, and the reduction to the fluid limit is then carried out.

Thermodynamic systems at equilibrium are characterized by fluctuations that are a manifestation of their discrete nature at microscopic scales. We have already seen some examples of such fluctuations: those in the number of particle \(\Delta N\) in a certain volume \(V\) of a gas; the energy fluctuations in a system in contact with a heat bath.

Quantum Theory of Fluctuations
Physical Review, 1955An operator is constructed for the spectral density of a fluctuating dynamical variable. The formulation is based on an analysis of method of measurement. An essential feature of the operator is the replacement of classical dynamical variables by time-dependent Heisenberg operators. The expectation value of the spectral density includes fluctuations of

Theory of fluctuations in a plasma
Annals of Physics, 1962Abstract A theory of electron density fluctuations in a two-component plasma of electrons and positive ions is developed within the random phase approximation. A dielectric formulation is used extensively to describe the fluctuations; investigation of various examples clarifies such facets as collective vs. individual particle aspects of fluctuations.

Physical Review E, 2000
The current status of the theory of stress fluctuations is marked by two circumstances: no currently available formulas are valid for a metallic system, and a series of contradictory formulas remains unresolved. Here we derive formulas for shear- and isotropic-stress energy fluctuations, in the primary statistical mechanics ensembles.

From a consideration of the physical phenomena involved in thermionic conduction and in thermal or Johnson noise, it is deduced that the noise in a space-charge-limited valve is best expressed as a thermal noise, and it is shown that a small correction must be applied to the valve slope resistance to give the value of resistance effective as a noise ...
