Abstract: A method for removing at least one pollutant from an aqueous environment comprises adding an acid to the aqueous environment to provide an acidic aqueous environment, adding a chelator solution directly to the acidic aqueous environment to achieve a precipitate of the at least one pollutant, and isolating the precipitate from the aqueous environment. The at least one pollutant may include any one or more of a heavy metal cation, an organic dye, and an active pharmaceutical ingredient.

Abstract: A method for identifying a current context and determining a sensor combination based on the current environment. The method may comprise accepting a plurality of sensor outputs and implementing a CNN to convert the sensor outputs into a plurality of features that can be used to identify the context through use of a gating algorithm that additionally determines which sensors have the most importance and which have little or no importance. The method may further comprise executing sensor fusion in a manner corresponding to the context. For example, the context determines whether early fusion or late fusion should be implemented and which sensor outputs should be included in the said fusion.

Abstract: A method of reducing corrosion in tubular strings installed in wellbores includes dispensing an accelerated cement composition into a wellbore annulus, a casing-casing annulus, or both, the accelerated cement composition comprising a cement composition and an accelerant composition, where: the cement composition comprises a cement precursor and water; the accelerant composition comprises triethanolamine; and a concentration of the triethanolamine in the accelerated cement composition is greater than or equal to 10,000 parts per million by weight; allowing the accelerated cement composition to cure in the annulus to form a cured cement, where the triethanolamine reacts with a metal of the tubular string, the reaction forming a protective layer on the surfaces of the tubular string that inhibits dissolution of iron from the metal of the tubular string.

The present invention features a computing system comprising instructions for accepting the one or more images, extracting one or more objects from each image, computing an inverse-perspective mapping transformation of the image to generate a bird's-eye view (BEV) representation of each image, calculating relations between each object for each image, and generating a scene-graph for each image based on the aforementioned calculations. The system may further comprise instructions for calculating a confidence value for whether or not a collision will occur through the generation of a spatio-temporal graph embedding based on a spatial graph embedding and a temporal model.

Abstract: A structure for magnetic flux sensor conditioning is presented which partitions an input analog signal of unknown integrity into two: susceptible and insusceptible. The structure scrutinizes the susceptible signal partition, in view of additional guard sensor information, through a mixed-signal processing side-chain that employs a non-invasive physical magnetic attack detection algorithm. The side-chain either validates, or replaces with a best estimate, the susceptible signal partition, depending upon the absence or presence of attack, respectively. The structure finally recombines the scrutinized susceptible signal partition with the insusceptible signal partition. The result is an analog magnetic flux sensor signal that is robust against skillful, surreptitious, spoofing attacks. If unmitigated, such attacks may induce catastrophic consequences into systems relying upon the magnetic flux sensor.

Abstract: A solids removal apparatus for glycol reclamation includes a first tubular, a second tubular, and a strainer. The first tubular includes an open end configured to receive a brine stream including solid material. The second tubular is connected to and protrudes from the first tubular. The second tubular is configured to discharge an outlet stream. The strainer is disposed within the second tubular. The strainer is configured to prevent at least a portion of the solid material from flowing through the strainer, such that the outlet stream discharging from the second tubular has a solids content that is less than a solids content of the brine stream.

Abstract: In an embodiment, an ice-prevention dam for a pitot tube includes a body and a head. The body includes a notch having a substantially planar back, and the head extends from the body and has a substantially planar side that is substantially parallel to the back of the notch. Such a dam can prevent ice accumulation in a pitot tube, and can facilitate proper positioning of the dam. For example, during manufacture of a pitot tube, an assembler inserts the dam into a hole in a side of a pitot-tube body having a front opening such that the head of the dam is located outside of the pitot-tube body and a body of the dam is located inside of the pitot-tube body. Next, the assembler positions the dam by causing the substantially planar side of the dam head to be substantially parallel with the front opening of the pitot-tube body.

Abstract: A methodology as described herein allows cyber-domain tools such as computer aided-manufacturing (CAM) to be aware of the existing information leakage. Then, either machine process or product design parameters in the cyber-domain are changed to minimize the information leakage. This methodology aids the existing cyber-domain and physical-domain security solution by utilizing the cross-domain relationship.

Abstract: A physical layer secret key generation scheme exploiting randomness of the road surface and driving behavior is described herein. A symmetric key generation scheme can be implemented in any existing V2V visible light communication. By analyzing and simulating numerous samples taken from NGSIM vehicle trajectory data, the natural driving behavior and road surface roughness can be exploited as a source of randomness to generate symmetric cryptographic security keys.

Abstract: Point Optical Link communication security to help resolve the high resource requirements and lack of a trustworthy source of high randomness of existing communication security solutions is described herein. The scheme includes a novel model and a physical layer symmetric cryptographic key generation technique that focuses on exploiting the physical randomness manifested by the Polarization Mode Dispersion effect. This randomness makes it extremely difficult for an adversary to generate the same cryptographic keys as the communicating parties. 128 bit keys with low final mismatch rates (.ltoreq.10%) can be generated, which could easily be truncated for 64-bit and 32-bit keys if necessary.
