Abstract: A splint system includes a first base member including at least one connector portion. A second base member including at least one connector portion having a cavity, wherein an interior surface of the cavity includes slidable portions and coupling portions, the first and second base members being aligned to form a longitudinal passage. A shaft member is disposed in the longitudinal passage, and when the coupling portions of the shaft member align with the coupling portions of the second base member, the first and second base members are fixed relative to each other.

Abstract: Conventional techniques for automatically evaluating and grading assignments are generally ill-suited to evaluation of coursework submitted in media-rich form. For courses whose subject includes programming, signal processing or other functionally expressed designs that operate on, or are used to produce media content, conventional techniques are also ill-suited. It has been discovered that media-rich, indeed even expressive, content can be accommodated as, or as derivatives of, coursework submissions using feature extraction and machine learning techniques. Accordingly, in on-line course offerings, even large numbers of students and student submissions may be accommodated in a scalable and uniform grading or scoring scheme. Instructors or curriculum designers may adaptively refine assignments or testing based on classifier feedback.

Abstract: A quadrant based PNG image file may be used to encode compressed map information for a game map that is navigated during gameplay. The PNG image file encoded with compressed map information may be communicated to a gameplay device, which may decompress and decode the PNG image file to obtain the map information and generate the game map. Leveraging the lossless compression capabilities of the PNG image file format or other lossless image file format may reduce storage requirements and/or network bandwidth when playing the video game. Each pixel of the PNG image file may be used to encode multiple map tiles, allowing game maps to scale to large sizes while further leveraging the advantages of encoding the map information into the image file.

Abstract: The disclosure relates to systems and methods for facilitating data model substitution related to one or more pre-existing data objects in an expression of a game environment. A system may facilitate scalable addition of new game content by leveraging pre-existing data objects at a client computing platform. The system may include a game server that provides to the client computing platform data model substitutions for the existing data objects. The data model substitutions may be used to alter the behavior or function, look (e.g., visual appearance), description, and/or other characteristic of an expression of a pre-existing data object. Thus, by leveraging pre-existing data objects and providing such data model substitutions, new content or at least the appearance of new content from the user's perspective, may be provided without revising client code or requiring downloading new instructions that encode new data objects.

Abstract: A pyrophoric material comprises a pyrophoric metal coated onto a wire mesh substrate. Iron and nickel are the preferred metals and a steel wire mesh is suitable. A process for making the pyrophoric material involves spraying an alloy of iron and/or nickel with aluminium onto a mesh using a high velocity oxy-fuel (HVOF) process following by leaching out at least a proportion of the aluminium by treatment with an alkaline solution. The product has application as a supported catalyst or as either an ignition medium or as a flare material in military countermeasures in which applications it is capable of burning at a high temperature.

Abstract: Processes for polymerizing propylene. About 40 wt % to about 80 wt % propylene monomer, based on total weight of propylene monomer and diluent, and about 20 wt % to about 60 wt % diluent, based on total weight of propylene monomer and diluent, can be fed into a reactor. The propylene monomer can be polymerized in the presence of a metallocene catalyst and an activator within the reactor at a temperature of about 80° C. or more and a pressure of about 13 MPa or more to produce a polymer product in a homogenous system. About 20 wt % to about 76 wt % (preferably About 28 wt % to about 76 wt %) propylene monomer, based on total weight of the propylene monomer, diluent, and polymer product, can be present at the reactor exit at steady state conditions.

Abstract: A method for preparing a high-purity ionic liquid having a pH value of 7 and an elemental analysis deviation of less than 0.5 wt % between a calculated elemental analysis and a found elemental analysis for each of carbon, hydrogen and nitrogen, wherein the method comprises forming a monophasic or biphasic mixture of an ionic liquid and an inert liquid. When the monophasic mixture is formed, it is filtered to yield a filtrate from which the high-purity ionic liquid is recovered. When the biphasic mixtures is formed, it is separated into an aqueous phase and ionic liquid phase, whereby the ionic liquid phase is filtered to yield a filtrate from which the high-purity ionic liquid is recovered. Furthermore, the present purification procedure can be used for the clean-up of a contaminated ionic liquid by extracting it into a polar extractant to form an extract containing the ionic liquid. Water traces are removed from the extract.
