Abstract: A composite fan casing for a turbine engine includes a core including a plurality of core layers of reinforcing fiber bonded together with a resin. The core includes a first surface and an opposing second surface. The fan casing also includes a shock dispersion panel coupled to the first surface, wherein the shock dispersion panel is configured to disperse a shock wave caused by an impact on the second surface to prevent separation of the plurality of core layers.

Abstract: An additive manufacturing apparatus includes: a build module comprising a build chamber, and a least one of but less than all of the following elements: (a) a directed energy source; (b) a powder supply; (c) a powder recovery container; and (d) a powder applicator; and a workstation comprising the remainder of elements (a)-(d) not included in the build module.

Abstract: One or more light sources emit light within first, second, and third wavelength ranges through exhaust gas. The first and second wavelength ranges are characterized by first and second different absorption wavelength ranges of a background gas. The third wavelength range is characterized by an absorption wavelength range of a gas-of-interest. At least some of the light within the first, second, and third wavelength ranges is absorbed by the exhaust gas thereby providing modified light characterized by the first, second, and third absorption wavelength ranges. One or more detectors receive the modified light. A processing subsystem determines a temperature of the exhaust gas based on the modified light characterized by the first and second absorption wavelength ranges and a concentration of the gas-of-interest based on the modified light characterized by the third absorption wavelength range and the temperature of the exhaust gas.

Abstract: A system and method of operating a dual-beam detection system of a holographic data storage disc, including: impinging a data beam on a data layer of the holographic data storage disc; impinging a tracking beam on a tracking element of the holographic data storage disc; detecting a reflection of the tracking beam from the tracking element; and coordinating position of the data beam relative to the tracking beam.

Abstract: A method and a system for analyzing infrastructure are provided. In one embodiment, a system for analyzing infrastructure is provided. The system includes a grid intelligence quotient as a service (GIQAAS) system. The GIQAAS system includes an infrastructure data gathering system having a first input form configured to collect an economic data related to an infrastructure. The GIQAAS system further includes an economic modeling system configured to import the economic data and to derive an economic analysis based on the economic data. The GIQAAS system is configured to provide the infrastructure data gathering system to a first user for collection of the economic data, and to provide the economic modeling system to a second user for derivation of the economic analysis.

Abstract: Embodiments of the invention relate to a method of processing a radiological image of an organ, the organ being connected to a flow circulation network, and comprising steps according to which: an operator or a processing means defines a contour to delimit a zone of interest in the radiological image of the organ; the processing means determines part of the network in which the flow supplies the zone of interest or originates from this zone of interest; and a display means displays the determined part of the network.

Abstract: A roller bearing that provides ball and roller bearing elements comprised of M50 steel and M50NiL steel having surface hardnesses above 60 HRC, and in the range of 65-72 HRC. The hardness in the surface region is achieved by nitriding the surface to achieve a high hardness and extended life. This improvement is brought about by controlling the microstructure of the alloy by minimizing the formation of retained austenite. The material is tempered as required. The surface is then nitrided, but the nitriding operation is carefully controlled to avoid the formation of intergranular nitrides. Because of the method used to prevent the formation of intergranular nitrides, some carbon may be present to prevent the surface of the steel from becoming depleted of carbon. The hardening element in this nitro-carburizing operation is nitrogen, which forms iron nitride as Fe3N or Fe4N intragranularly.
