Abstract: A hydraulic fracturing system and method uses a model trained with external pressure gauge data and LFDAS sensor data to identify pressure communication events based on LFDAS sensor data. One or more monitoring wells are established in proximity to a well undergoing well stimulation, each monitoring well including one or more LFDAS sensors. LFDAS sensor data is received from the LFDAS sensors of the one or more monitoring wells, the received LFDAS sensor data including data received after start of a well stimulation operation. Occurrences of pressure communication events at each monitoring well may then be identified based on the model and on the received LFDAS sensor data.

Abstract: A sheath assembly for the insertion of a percutaneous pump includes a tubular sheath body dimensioned for insertion into a blood vessel through a vessel aperture. The tubular sheath body includes a wall having a proximal end portion, a distal end portion, a longitudinal axis, an outer surface, an inner surface defining a first lumen substantially parallel to the longitudinal axis, and a second lumen disposed within the wall between the inner surface and the outer surface and extending from the proximal end portion to the distal end portion. The first lumen is dimensioned to allow passage of a portion of the percutaneous pump, and the second lumen is dimensioned for passage of a guidewire. A stylet is removably positioned to substantially occlude the second lumen. The stylet has a proximal end releasably secured to the sheath assembly.

Abstract: An endless track assembly that mounts to a vehicle drive linkage. The track assembly includes a belted track, drive sprocket, framework and sets of ramp/road and idler/road wheels that support interior track surfaces. Idler axles are secured fore and aft of co-planar pivot members at rocker assemblies laterally interleaved between suspended idler/road wheels laterally spanning the framework. Each rocker assembly supports an elastomer cushion on a rocker plate that pivots in a housing between opposed wear plates to compress and expand and resist pivoting rocker plate movements.

Abstract: Techniques are provided for estimating an optimal radiation dose for x-ray imaging. A methodology implementing the techniques according to an embodiment includes operating an x-ray sensor at a first gain setting. The method also includes capturing a scouting image at the first gain setting using a scouting image radiation dose. The method further includes employing a radiation dose model to provide a diagnostic image radiation dose based on the scouting image. The diagnostic image radiation dose is greater than the scouting image radiation dose. The method further includes operating the x-ray sensor at a second gain setting. The second gain setting is less than the first gain setting. The method further includes capturing a diagnostic image using the provided diagnostic image radiation dose.

Abstract: Disclosed is a system and method for sealing an opening through the boundary of a controlled thermal and gaseous environment such as an incubator or refrigerator, where conduit channels of arbitrary size and number are transferred across the boundary. A silicone or polymeric tube with flanges at either end is passed through the boundary opening, fixing one side to the boundary wall and attaching the other to a mechanism that controls or constrains the rotation of the tube. This is achieved by rotating or twisting one end of the tube, creating a hyperboloid-like structure that will seal around the conduits and thereby seal the opening. To further improve thermal efficiency, insulating material such as expanded polystyrene beads are placed into the space between the silicone or polymeric tube and the wall of the incubator, providing thermal stability that cannot be achieved by conventional conduit transferring methods.

Abstract: The invention is directed to a method for designing cement slurry compositions based on toughness. The method addresses the problem of achieving a cement slurry with a desired toughness by iteratively selecting a cementitious material and water, including their concentrations, to form a cement slurry recipe. A toughness model, utilizing physicochemical properties of the recipe components, calculates the toughness of the slurry. The calculated toughness is compared to a predetermined toughness requirement. If the requirement is not met, the selection process is repeated with different materials or concentrations until the toughness requirement is satisfied. The resulting cement slurry recipe is used to prepare a cement slurry suitable for applications requiring specific toughness characteristics such as in wellbore cementing.
