Abstract: Methods and systems are provided for retrieving aggregate social media content metrics from a back end data store using a time series cache. The method involves populating the data store with social media content received from a plurality of social media content sources, periodically prefetching respective time series data packets from the data store, storing the prefetched time series data packets in a time series cache, retrieving, from the time series cache, a sequence of the prefetched time series data packets responsive to a user query, and presenting indicia of the sequence of the prefetched time series data packets to the user. Each time series data packet represents an aggregate of data which satisfies a topic profile for a predetermined window of time.

Abstract: A flexible, calenderable film exhibiting enhanced durability under external weathering conditions. The film comprises predominantly a base layer of a graft copolymer of vinyl chloride on polyacrylate laminated with an acrylic based protective layer. Importantly, the base layer is devoid or contains minimal plasticiser components to eliminate or reduce UV absorber migration from the acrylic based protective layer.

Abstract: A method of manufacturing an annular wall (46) of a combustion chamber (15) comprises depositing layers of a metal sequentially one upon the other to form layers of a spiral wall (45) of the combustion chamber (15). Each layer of metal is deposited in a spiral pathway (122). The ends (E1, E2) of the spiral wall (45) of the combustion chamber (15) are joined together to form the annular wall (46) of the combustion chamber (15). The ends (E1, E2) of the spiral wall (45) of the combustion chamber (15) are at the opposite ends of the spiral pathway (122).

Abstract: New 7XXX alloys having improved ballistics performance are disclosed. The new alloys generally are resistant to armor piercing rounds at 2850 fps, resistant to fragment simulated particles at 2950 fps, and are resistant to spalling. To achieve the improved ballistics properties, the alloys are generally overaged so as to obtain a tensile yield strength that is (i) at least about 10 ksi lower than peak strength and/or (ii) no greater than 70 ksi.

Abstract: A self-service system is provided that can automatically identify one or more existing groups to which a user can self-select to access a resource. The self-service system can identify any suitable existing group without requiring an administrator to predefine groups according to roles. In some implementations, the system intelligently identifies one or more suitable groups for a user from a list of available groups by analyzing a set of rules or criteria. For instance, the system can perform a weighted analysis of various rules and/or criteria to automatically and dynamically identify groups that have a closest fit to the access rights needed or requested by the user. Further, the system can evaluate certain best or preferred grouping practices to identify suitable groups. As a result, in certain embodiments, the self-service system alleviates planning burdens on administrators and provides greater flexibility in providing users with access to resources.

Abstract: A method of manufacturing a thermal barrier coated article including the steps of: a) forming an article having a first surface and a second surface, the article having a plurality of projections extending from the first surface in a direction away from the first surface and away from the second surface, each projection having a first end adjacent the first surface and a second end remote from the first surface, b) depositing a thermal barrier coating on the first surface of the article around each of the projections and on the second ends of the projections, c) removing the thermal barrier coating from the second ends of the projections, and d) forming at least one passage through each projection extending from the second surface of the article through the article and through the respective projection to the second end of the respective projection.

Abstract: A lower cost combustor is formed from a series of sheets of metal that are secured by mechanical fasteners. An increase in diameter of the combustor is achieved through the provision of securing rings to which the sheets of metal are secured.

Abstract: A system for testing visual fields comprising a display for presenting a visual stimulus and an eye tracker for tracking movement of at least one of a patient's eyes to determine its position in three dimensions without requiring the patient to wear any tracking equipment. A computer controls the position of the stimulus on the display and causes it to move by an amount that is a function of the tracked three-dimensional position of the patient's eye and a visual field position that is to be tested. Changes to the position of the stimulus and any corresponding tracked eye movement are used to assess the patient's visual field.

Abstract: The present disclosure relates to methods, systems, and devices that may be used to heat treat and store one or more fluids.

Abstract: A particle damper is formed using a solid freeform manufacturing technique. A filler provides support for the closing wall of the cavity as it is formed. Apertures allow at least a portion of the filler to be removed. A particle fill of between 90 and 95% is achieved either by removing sufficient filler to reach this fill or removing excess filler and re-filling with damping particles.
