Factorable

Invariant Pattern Recognition: Towards Neural Network Classifiers of all invariances simultaneously: scale and projection can be processed in a single filter [1], but a pre-processing is necessary for the rotation before any object recognition, since the projection and scale invariant filter do not work on rotated objects.

Exclude

Binary, Multilevel, and Hybrid Holographic Optical Array Illuminatorsfabricate, but they require uniform plane-wave illumination that is difficult to provide. Space-invariant array illuminators generate the spot array in the Fourier plane and are therefore rather immune to the exact shape of the incident beam, but they are more difficult to design and require tight fabrication tolerances.

Asperity

Predictions of Large Optical Nonlinearities in Quantum Well Wiresening effects are found to have relatively little influence. For all plasma densities . (including . = 0), the free-carrier transition spectra differ strongly from those calculated with Coulomb interaction.

Classify

Synthesis of Diffractive Optical Elements Using Electromagnetic Theory of Gratingsparable to the wavelength of light [3,4]. The analysis and design of gratings operating in this region, which we call the resonance domain, must be based on the electromagnetic vector diffraction theory. Several numerical methods have been proposed and applied to solve the rigorous diffraction problem [5,6,7].

Wide Bandgap II–VI Light Emitting Devicesma discharge source as the p-type dopant. LEDs have been fabricated using a gold contact to the p-type layer and blue CW emission has been observed under forward bias. Stripe geometry laser structures have been fabricated and blue stimulated emission has been observed for the first time at low temperatures.
