Abstract: An augmented reality system to perform operations that include: accessing image data at a client device; determining a position of a user of the client device based on the image data; causing display of a projection that extends from the position of the user upon a presentation of the image data at the client device; detecting an intersection of the projection and a surface of an object; generating a request that includes an identification of the portion of the surface of the object at the client device; and presenting the portion of the surface of the object based on the graphical property of the projection at the client device in response to the request that includes the identification of the portion of the surface of the object.

Abstract: A method for advanced nitrogen and phosphorus removal in sewage treatment includes the following steps: feeding raw water and return sludge into a pre-denitrification zone for denitrification; allowing a sludge-containing mixed liquor discharged from the pre-denitrification zone to enter an anaerobic zone to undergo a biological phosphorus removal reaction; allowing a sludge-containing mixed liquor discharged from the anaerobic zone and a return nitrification liquid to enter an anoxic zone for denitrification; allowing a sludge-containing mixed liquor discharged from the anoxic zone to enter an aerobic zone for nitrification and excessive phosphorus uptake, and allowing part of a nitrification liquid to be returned to the anoxic zone; allowing a sludge-containing mixed liquor discharged from the aerobic zone to enter a sedimentation zone for separation; passing a resulting supernatant through a biological filtration zone; returning part of resulting sludge to the pre-denitrification zone; and the like.

Abstract: The invention discloses a method for improving a recovery ratio of a braided well pattern of a hugely thick or multi-layer oil and gas reservoir, which improves the recovery ratio of the hugely thick or multi-layer oil and gas reservoir by designing the braided well pattern. The braided well pattern is designed through the following method: dividing a cubic development unit of the oil and gas reservoir; measuring a physical property parameter of the cubic development unit; calculating a well pattern design parameter according to the physical property parameter, wherein the well pattern design parameter includes a number of wells and a well bore track; and drilling a large-displacement horizontal well according to the well pattern design parameter.
