The Bidirectional Reflectance Distribution Function (BRDF) provides a quantitative means of characterising how light is reflected from a surface. It is defined as the ratio of radiance scattered ...

The function can be used to calculate all moments. For instance, a function with modulus or peak value, standard deviation, and mean of the distribution as parameters requires three moments for ...

To unlock the complex structure and behavior of 1T Phase Tantalum Disulfide, researchers used the Pair Distribution Function (PDF) beamline at the National Synchrotron Light Source II (NSLS-II), a ...

Two new methods are suggested for estimating the dependence function of a bivariate extreme-value distribution. One is based on a multiplicative modification of an earlier technique proposed by ...

A robust procedure is developed for estimating density functions from data. It requires the existence of a parametric function, called the key function, to give a first approximation to the density ...
