Abstract: Embodiments of systems and methods to determine depth of soil coverage for an underground feature along a right-of-way are disclosed. In an embodiment, the method may include receiving a depth of cover measurement for the right-of-way. The method may include capturing baseline images of the right-of-way within a first selected time of the depth of cover measurement. The method may include rendering a three dimensional elevation model of the right-of-way from the baseline images. The method may include georeferencing the three dimensional elevation model to generate a georeferenced three dimensional elevation model. The method may include adding the depth of cover measurement to the georeferenced three dimensional elevation model. The method may include rendering an updated three dimensional elevation model of the right-of-way from subsequently captured images. The method may include determining a delta depth of coverage based on the georeferenced and the updated three dimensional elevation model.

Abstract: Embodiments of systems and methods to determine vegetation migration encroachment along a right-of-way associated with an underground feature are disclosed. In an embodiment, the method may include capturing images of one or more sections of the right-of-way at a selected time period. The method may include georeferencing the images to correlate the images with a surface of a geographical location of the right-of-way. The method may include determining and clipping an area of interest for the images. The method may include tiling clipped images to a preselected size to define a plurality of tiled clipped images. The method may include determining a vegetation migration encroachment onto the right-of-way by application of the clipped images to the trained machine learning model. The method may include, in response to a determination that the vegetation migration encroachment exceeds a threshold, generating an indication of vegetation migration encroachment.

Abstract: Per-and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water can be concentrated and prepared for destruction in a pretreatment phase. Following annihilation of the PFAS in supercritical conditions to levels below 5 parts per trillion (ppt), the water effluent can be used to recover heat, returned to sub-critical conditions, and then released back into the environment.

Abstract: An intake body, systems, and method for reducing acoustic resonance in pressure tap passages include determining and/or setting the length of the drilling tap passages to a value such that the natural frequency of each pressure tap passage is outside of or does not substantially overlap with operational frequency content of an air stream in the intake body. The intake body, systems and method reduce the possibility of exciting the natural acoustic frequencies of the pressure tap passages, and can lead to improved signal-to-noise ratio when detecting EGR flow using a delta-P measurement system.

Abstract: An inspection system is provided for inspecting a generator including a rotor and a stator substantially surrounding the rotor. The rotor has a first end with a first circumference, and a second end with a second circumference. The inspection system includes first and second retaining rings disposed at or about the first and second ends of the rotor, and first and second motion control modules movably coupled to the first and second retaining rings. The first and second motion control modules are interconnected and guide a carriage assembly therebetween in order to perform an operation on the generator. At least one of the first and second motion control modules is structured to receive the carriage assembly and to move around the corresponding first or second circumference of the generator rotor, in order to align the carriage assembly with stator slots of the stator of the generator.
