A device representing a reflector, for example an evanescent reflector or a multilayer interference reflector, with at least one reflectivity stopband is disclosed. A medium with means of generating optical gain is introduced into the layer or several layers of the reflector. The optical gain spectrum preferably overlaps with the spectral range of the reflectivity stopband.

For example, volume Bragg gratings, distributed feedback gratings or patterns, using of vertical optical cavities surrounded by multilayer Bragg reflectors can be applied. The optical modes of the passive optical cavity partially penetrate into the gain region of the reflector. As a result of the interaction of the gain medium in the reflector region and the passive cavity modes, photons are generated or amplified in the passive cavity at wavelengths defined by the passive cavity modes. The materials selected for the passive cavity layers are chosen to provide the necessary temperature dependence of the effective index of refraction of the related optical modes of the passive cavity and serve as a tool to achieve the controlled temperature dependence of the wavelength of the emitted photons. In particular a complete suppression of the wavelength to temperature variations can be achieved. In another case a strong shift of the resonant wavelength or wavelengths with temperature may be realized. Thus the structure represents an optoelectronic device with controlled temperature dependence of the emission wavelength. |

Deblurring and supervised adaptive thresholding for print-and-scan document image evaluation
A method is described to obtain a binary image from the print-and-scan process to best match the known original. A point-spread function (PSF) of the PAS process is first obtained from its knife-edge responses, and deblurring is carried out on the scanned images using deconvolution. After image deskewing and preliminary registration, a supervised adaptive thresholding procedure is utilized to binarize the scanned image such that a measure of difference (e.g. the Euclidean distance) between the original and binarized images is minimized. The supervised adaptive thresholding procedure divides the scanned images into many rectangular sub-images. Otsu's method is used to find a starting threshold for each scanned sub-image. An optimal threshold is found around the Otsu's threshold via iterative search to minimize the measure of difference between the original sub-image and scanned sub-image. The sub-images are binarized using the optimal threshold. This method may be used in document authentication. |

Nickel-based reforming catalysts
The present invention relates unique pore structures in nickel supported on alumina with the negligible formation of macropores. Incorporation of additional elements stabilizes the pore structure of the nickel supported on alumina. Additional element(s) were then further added into the nickel-supported materials. These additional element(s) further stabilize the pore structures under heating conditions. The improvements of pore structure stability under heating conditions and negligible presence of macropores limit the sintering of nickel metal to a mechanism of impeded diffusion. The negligible presence of macropores also limits the deposition of alkali metal hydroxide(s)/carbonate(s) on the outer shell of the catalyst pellet in the molten carbonate fuel cells. Both the negligible presence of macropores and improvement in pore structure stability allow for prolonging the catalyst life of these nickel supported on alumina catalysts of the present invention for reforming hydrocarbons. |
