Thus, the uncertainty of an individual position datum depends significantly on the magnitude of the charge that generated it. In most instances, the electronics used for position evaluation will have a limited dynamic range. It is often difficult to set the gain of the detector so that all ...
Instead, we loosely define the path length as the distance required for the average electromagnetic intensity to decay to e−1 of its original magnitude when (repeatedly) propagating through the sample, meaning the value at which \(\bar{A}(\Omega )=1\) (assuming Arrhenius-type isotropic ...
Modulation of perceived contrast by a moving surround Multiresolution wavelet framework models brightness induction effects The perceived contrast of texture patches embedded in natural images. The magnitude of center-surround facilitation in the discrimination of amplitude spectrum is dependent on the amplitu...
Those show a strong dependence on voltage and illumination intensity, because charge-carrier densities change by orders of magnitude upon varying these parameters in a solar cell. Examining the logarithmic plots of the JV curves (forward scan) for the negative-capacitance device from Fig. 5a in ...
Parallax, Apparent Magnitude and Absolute Magnitude We have seen that the flux F and luminosity L of a star (or any other light source) are related via the equation: F D L 2 4π = Trigonometric Parallax Hence, to determine the luminosity of a star from its flux, we also need to know...
The apparent magnitude of a complex shaped space object is difficult to calculate since its visible triangular facets are hard to be determined. The most common-used visible facets determination method is to judge the incident and emergent angle, but this method does not apply to a space object...

Since SIF is orders of magnitude lower than the TOA radiance reaching the sensor, it can be physically considered as a small perturbation of Equation (3): 𝐿𝑠𝑒𝑛=𝐿0+(𝐸𝜋·𝜌+𝐹·)𝑇↑(1−𝑆·𝜌)=𝐿0+𝐸·𝜌𝑎𝑝𝑝𝑇↑𝜋(1−𝑆·𝜌),Lsen=L...
