Abstract: A method of making a structural lightweight and thermal insulating concrete is described. The concrete has a coarse aggregate partly replaced by recycled plastic pieces. This enables the concrete to maintain a high compressive strength, low thermal conductivity, and low weight, while providing a use for waste plastic. The waste plastic pieces may comprise polyethylene in the form of flakes, fibers, or granules. Due to its low unit weight, adequate compressive strength and high thermal resistance the developed concrete can be used as a structural lightweight and thermal insulating concrete. The use of this concrete leads to economic and environmental benefits.

Abstract: A gear assembly includes a primary shaft, a driving gear, a driven gear, a secondary shaft, and a key wherein the primary shaft and the driving gear define a keyway for housing the key. The primary shaft defines a lower region of the keyway while the driving gear defines an upper region of the keyway. The driving gear may be mounted on the primary shaft such that the upper region and the lower regions of the keyway are aligned with each other in order for the keyway to house the key. The driven gear may be mounted on the secondary shaft such that the driven gear may be in meshing engagement with the driven gear. The aforementioned keyway defines a peninsula in a center portion of the driving gear. The peninsula is configured to abut a key disposed within the keyway.

Abstract: A method and system for non-disruptive host repurposing. Specifically, the method and system disclosed herein entail the re-optimization of datacenter hosts (e.g., servers) for any infrastructure and/or workload deployment. Different infrastructure and/or workload deployments may require the tuning of various memory parameters (or attributes) in the basic input-output system (BIOS) configuration. Presently, the repurposing of any given host demands the full reset of the system configuration—i.e., a disruptive process—prior to implementing the necessary BIOS configuration changes. In contrast, the method and system disclosed herein facilitate the repurposing of a host through the installation and/or uninstallation of configuration overlays—a modular approach to interchanging infrastructure and/or workload deployments—without the disruption of full system resets.

Abstract: An internal combustion engine is configured to periodically open and close combustion chamber exhaust valves of the engine such that one exhaust valve is held open longer than another exhaust valve and/or one exhaust valve opens before another exhaust valve relative to top dead center. The resulting differential exhaust valve timing can at least partially compensate for different swallowing capacities of the scrolls of a twin-scroll turbine.
