Abstract: A positioning method that calculates a lower accuracy positioning solution and applies an offset to the lower accuracy positioning solution to form a final positioning solution if a higher accuracy positioning solution is unavailable. The offset represents a difference between the lower accuracy positioning solution and the higher accuracy positioning solution at a point in time when the higher accuracy positioning solution was last available.

Abstract: The strain-managed optical waveguide assemblies of the present invention utilize a large-mode-area (LMA) optical fiber that is annealed in a first bending such that the fiber in that configuration has substantially no axial strain. A fiber support member is then used to support the annealed LMA optical fiber in a second bending configuration that forms within the LMA optical fiber an axial strain profile that reduces stimulated Brillouin scattering (SBS) as compared to the first bending configuration, and that also preferably causes the LMA optical fiber to operate in a single mode. The LMA optical fiber may have a double-clad configuration and include a doped core that serves as a gain medium. The strain-managed optical waveguide assembly can then be used to constitute a fiber amplifier that mitigates the SBS penalty associated with high-power fiber-based optical systems. The strain-managed waveguide assembly can also provide for thermal management in high-power applications, and can be used to control SBS by controlling the temperature profile along the length of the LMA optical fiber in a manner that mitigates SBS.

Abstract: An isotopically-altered, silica based optical fiber is provided having lower losses, broader bandwidth, and broader Raman gain spectrum characteristics than conventional silica-based fiber. A heavier, less naturally abundant isotope of silicon or oxygen is substituted for a lighter, more naturally abundant isotope to shift the infrared absorption to a slightly longer wavelength. In one embodiment, oxygen-18 is substituted for the much more naturally abundant oxygen-16 at least in the core region of the fiber. The resulting isotopically-altered fiber has a minimum loss of 0.044 dB/km less than conventional fiber, and a bandwidth that is 17 percent broader for a loss range between 0.044-0.034 dB/km. The fiber may be easily manufactured with conventional fiber manufacturing equipment by way of a plasma chemical vapor deposition technique. When a 50 percent substitution of oxygen-18 for oxygen-16 is made in the core region of the fiber, the Raman gain spectrum is substantially broadened.

Abstract: A client updates a display of a user interface associated with a state-based client-server application in accordance with a client-side cache. The server supplies data for a new state and additional data for one or more subsequent states that possibly follow the new state if appropriate one or more operations are performed. When a client request is generated that indicates an operation that causes the application to transition to the new state, the client updates the display in accordance with the data that corresponds to the new state from the client-side cache, if available from the client-side cache. The new state data is available since the server has previously supplied the new state data.

Abstract: In a process/system for the purification of aromatic dicarboxylic acid (ACA), crude ACA solids are slurried with water recycled from at least a filtration step in a feed preparation zone. Flash steam in vapour phase is supplied to the zone from at least one of a crystallisation step, a filtration step, and a drier step. The slurried ACA solids are preheated to form a solution that is then hydrogenated. The ACA is allowed to crystallise and then crystals of pure ACA are filtered out and water is recovered in a single stage filtration process. Recovered water is supplied to the feed preparation zone and the crystals are dried and recovered. The flash steam recovered from the crystallisation step, filtration step and/or drier step is recovered as a vapour phase stream having a pressure from about atmospheric to 5 barg and supplied to the feed preparation zone without phase change.

Abstract: Response delay associated with a state-based client-server application can be reduced with utilization of an application state server-side cache. A server caches data for a set of one or more possible states of a client-server application that may follow a current state of the application. The server rapidly responds to a client request with data that corresponds to an appropriate new state of the application in accordance with the application state server-side cache. The server determines that the application will transition to the appropriate new state from the current state of the application with the application state server-side cache based, at least in part, on an operation indicated by the client request.

Abstract translation: 与基于状态的客户端 - 服务器应用程序相关联的响应延迟可以通过使用应用程序状态服务器端缓存来减少。 服务器缓存可以遵循应用程序的当前状态的客户端 - 服务器应用程序的一组或多个可能状态的数据。 服务器根据应用程序状态服务器端缓存，快速响应客户端请求，该数据对应于应用程序的适当新状态。 服务器确定应用程序将至少部分地基于客户机请求指示的操作，从应用程序状态服务器端缓存的当前状态转换到适当的新状态。
