Variables Determining Flicker Sensitivity in Small Fields*

Journal of the Optical Society of America, 1970
The effect of size, luminance, and image movements on detection of flicker in small centrally located fields was studied with 12°, 1°, and 2° targets at average retinal illuminances of 26, 260, and 2600 td. When these fields were viewed in an essentially dark surround, a maximum of sensitivity was found at approximately 10 Hz.

Dark resonances with variable Doppler sensitivity

Physical Review A, 2005
We have studied dark resonances in a thermal gas of rubidium atoms using a variable angle between the two driving optical beams. The inclined angle was tuned between a Doppler-free situation (i.e., collinear beams) and near 10{sup -3} rad, yielding an effective Doppler sensitivity of a far-infrared photon.

Fixed and Variable Constraints in Sensitivity Analysis

SIAM Journal on Control and Optimization, 1980
Sufficient conditions are obtained for the $\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{C} ^1 $ dependence on a parameter of a local minimizes and associated Lagrange multipliers for parametrized families of nonlinear programming problems in which some constraints do not vary with the parameter. A class of sets, called “cyrtohedra”, with

Computing CHEMKIN Sensitivities Using Complex Variables

Part A: Combustion and Alternative Energy Technology; Computers in Engineering; Drilling Technology; Environmental Engineering Technology; Composite Materials Design and Analysis; Manufacturing and Services, 2001
Abstract This paper discusses an accurate numerical approach of computing the Jacobian Matrix for the calculation of low dimensional manifolds for kinetic chemical mechanism reduction. The approach is suitable for numerical computations of large scale problems and is more accurate than the finite difference approach of computing ...

Variable sensitivity of vectorial shearing interferometer

SPIE Proceedings, 2004
A vectorial shearing interferometer with variable sensitivity based in the rotation of a pair of wedge prisms is discussed. The prism rotations incorporates differential and extended wavefront controlled displacements, combining the advantages of high sensitivity of conventional interferometers and low sensitivity of traditional shearing ...
