Abstract: This disclosure describes a system and method for generating images and location data of a subsurface object using existing infrastructure as a source. Many infrastructure objects (e.g., pipes, cables, conduits, wells, foundation structures) are constructed of rigid materials and have a known shape and location. Additionally these infrastructure objects can have exposed portions that are above or near the surface and readily accessible. A signal generator can be affixed to the exposed portion of the infrastructure object, which induces acoustic energy, or vibrations in the object. The object with affixed signal generator can then be used as a source in performing a subsurface imaging of subsurface objects, which are not exposed.

Abstract: Techniques for simulating networks using dynamics-based constraints are disclosed.

Abstract: A method for producing renewable diesel includes introducing a primary feedstock comprising biologically-derived triglycerides with catalyst poisons into a first reaction chamber and hydrolyzing the primary feedstock within the first reaction and liquid-liquid extraction chamber for at least an hour such that the reacted triglycerides are separated into an aqueous solution comprising glycerol and catalyst poisons, and an intermediate feedstock comprising free fatty acids and catalyst poisons. The method also includes distilling the intermediate feedstock to separate the intermediate feedstock into a purified intermediate stream and a lower volume bottom stream containing unreacted triglyceride, diglyceride, monoglyceride, FFA and catalyst poisons. The method also includes combining the purified intermediate feedstock with a hydrogen stream and converting, in a second reaction chamber comprising a metallic catalyst bed, the purified intermediate feedstock into a product comprising long-chain alkanes.

Abstract: A configurable port fitting for a container, such as a bioprocess bag, has one or more O-ring grooves and two opposing locking arms (e.g., 604). The port fitting is mounted onto the container by (i) inserting one end of the port fitting into a port in the container such that O-ring(s) form seals between the O-ring grooves and the container and (ii) rotating the port fitting to engage the locking arms with two opposing retention clips (e.g., 506) of the container. Some port fittings are fixed port fittings that provide a fixed opening into the container. Other port fittings are port sizers that receive a valve connector that enables flow control between closed and open positions. Port fittings of different sizes enable different flow rates. Some port fittings (and other connectors) have a threaded tube barb that receives a threaded tube retainer that secures tubing in place over the barb.

A beam source generates the electromagnetic radiation beam. The electromagnetic radiation beam propagates from the beam source to the scanner along an optical path having an optical path length that varies in response to movement of the eye.

A representative system includes an uptake damper coupled to an uptake duct that receives exhaust gases from the coke oven and provides the exhaust gases to a common tunnel for further processing. The uptake damper includes a damper plate pivotably coupled to a refractory surface of the uptake duct and an actuator assembly coupled to the damper plate. The damper plate is positioned completely within the uptake duct and the actuator assembly moves the damper plate between a plurality of different configurations by causing the damper plate to rotate relative to the uptake duct. Moving the uptake damper between the different configurations changes the flow rate and pressure of the exhaust gases through the uptake duct, which affects an oven draft within the coke oven.

Based on the key points, a model of the fish is generated that provides an estimate of the size and shape of the fish. A regression model or neural network model can be applied to the fish model to determine characteristics of the fish.

Returning portions of the sample beam are processed so as to detect second locations on the optical surface beyond the first radial distance and within a second radial distance from the point.
