Abstract: The present disclosure provides an efficient map matching method for a global positioning system (GPS) trajectory, and belongs to the technical field of traffic. The efficient map matching method for a GPS trajectory includes the following steps: obtaining a valid GPS point list; obtaining a current searched end point; backtracking a best map matching path from the current searched end point, traversing GPS points along the path to obtain best matching results, and summarizing the best matching results to output a matching result statistical table; and determining whether the current searched end point is a final point. The present disclosure replaces the conventional “GPS point guided path search logic” with a “path search guided GPS point matching logic”, solves the problem of endless loop in backtracking of the emerging algorithm, avoids the complicated and inefficient map data calling process in the conventional matching logic, and greatly improves the map matching efficiency.

Abstract: A method for assembling a dual-head pulling rod involves attaching pulling heads to two ends of a rod body through threaded connection using a system that includes a foundation, on which a rod dispensing device, an inclined guiding plate, a conveying flap, a head dispensing device, a head mounting unit, a clamping device, an assembling device and a V-shaped output channel are provided. The inclined guiding plate is inclined and uses its ramp to guide a rod body falling thereon. The conveying flap is swingable between an input position and an output position. The conveying flap at the input position receives the rod body coining from the inclined guiding plate and outputs the rod body to the clamping device.

Abstract: The present embodiments relate generally to workload management and more particularly to a hybrid cloud workload management system and methodology which can effectively manage the execution of tasks of the same workload on both private and public clouds. In embodiments, user tasks are seamlessly and transparently executed on a public cloud if the private cloud does not have the necessary resources available. These and other embodiments automatically detect data dependencies of user tasks and build lists of data attributes of user tasks, which are used to populate and synchronize data needed for tasks before they are executed on the public cloud. Additional or alternative embodiments include the ability to intelligently scale the compute resources in the public cloud so that appropriate number of hosts with the resources needed by the user tasks are dynamically created and also properly purged upon user task completion.

Abstract: Rapid repair and retrofit of existing infrastructures demand durable high early strength materials that not only deliver sufficient strength within a few hours of placement but also significantly prolong the maintenance interval. The invention comprises a class of newly developed polyvinyl alcohol (PVA) fiber-reinforced high early strength engineered cementitious composites (ECC) materials featuring extraordinary ductility. The tailoring of preexisting flaw size distribution through non-matrix interactive crack initiators in the composite matrix results in high tensile ductility. The resulting high early strength ECC materials are capable of delivering a compressive strength of 21 MPa (3.0 ksi) within 4 hours after placement and retaining long-term tensile strain capacity above 2%.

Abstract: A staple for attaching together first and second metal sheets is made of a length of round wire bent at the ends to form spaced apart depending metal legs, each having a metal piercing point at the end thereof adapted to pierce completely through the first sheet and at least partially through the second sheet and also adapted to spread the legs further apart during the piercing to a spread position in which the legs are anchored within the metal sheets and thereby attach the metal sheets together. The metal piercing points each having an outside bevel surface on the outside of the leg, an inside bevel surface on the inside of the leg, and a blunt end surface between the inside and outside bevel surfaces.
