Abstract

There is provided a method for manufacturing a current flow diverter (CFD) for a superconducting segment. The method comprises depositing at least one pattern of stabilizer material on a portion of an outer surface of a superconducting layer of the superconducting segment and creating a first interfacial resistive layer on the outer surface, adjacent the stabilizer pattern, annealing, subsequent to depositing the stabilizer pattern, the superconducting segment in an oxygen atmosphere and creating a second interfacial resistive layer between the stabilizer pattern and the outer surface, the second interfacial resistive layer having an electrical resistance lower than that of the first interfacial resistive layer, and depositing, subsequent to annealing the superconducting segment, a stabilizer layer over at least the outer surface and creating at least one path for diverting, via the first and second interfacial resistive layers, a flow of electrical current from the superconducting layer to the stabilizer layer.

The ubiquity of cloud applications requires the meticulous design of cloud networks with high quality of service, low costs, and low CO2 emissions. The present invention relates to a method and system for optimizing the locations of cloud data centers or points of presence and software components while simultaneously finding the information routing and network link capacities by using an extremely efficient tabu search heuristic. The objectives are to optimize the network performance, the CO2 emissions, the capital expenditures (CAPEX), and the operational expenditures (OPEX). The problem is modeled using a mixed-integer programming model and solved with both an optimization solver and a tabu search heuristic.

Abstract

There is provided a method for the fabrication of porous SiC ceramic. The method comprises oxidizing particles of SiC ceramic thereby forming amorphous silica on the surface of the particles. The oxidized SiC particles are then mixed with an additive. Alternatively, layer(s) of the additive is (are) deposited on their surface by sol-gel technique. The oxidized SiC particles mixed or coated with the additive are then mixed with at least one pore-former. Alternatively, the oxidized SiC particles mixed or coated with the additive are coated with layer(s) of a polymer or pore-former by in-situ polymerization. In embodiments where the oxidized SiC particles are mixed with an additive and a pore-former or polymer, a further additive may be used. In each of these embodiments, the resulting product is then compacted into a green body which is heated and sintered to yield the porous SiC ceramic material. There is also provided a porous SiC ceramic fabricated by the method according to the invention.

Abstract

The present invention is based on the principle of depth of penetration of electromagnetic rays. In the case of semiconductor mono-crystalline materials, such as silicon, the depth of penetration of a light ray is proportional to its wavelength. Using this phenomenon, the present invention consists of a pixel having three electrodes that can discriminate between the colors red, green, and blue, and thereby reconstruct a color image.
