Tables of critically compiled wavelengths, line classifications, and transition probabilities are given for ionized spectra of neon (Ne V to Ne VIII), magnesium
A C++ object class library has been developed to distribute bidirectional reflectance distribution function (BRDF) models for light scattering from surfaces
This software algorithm combines a decade of experience in applying orthogonal distance regression and other iterative techniques to solving vector-network
Each of these techniques uses the process of optical parametric down-conversion (PDC) to produce correlated pairs of photons. This process employs a nonlinear
Our results extending Kuhn's fault class hierarchy provide a justification for the focus of fault-based testing strategies on detecting particular faults and
In this homepage, the history, construction, design and calibration of proving rings are given. The importance of force measurement and the principles involved
