摘要： A wastewater filter includes a vessel having a bottom and a side wall that cooperate to define a filter space. A first filter media is positioned within the filter space to define a first media layer, and a second filter media different from the first filter media is positioned within the filter space above the first media layer to define a second media layer, the first media layer and the second media layer cooperating to define an interface plane. A draft tube is positioned within the second media layer and has a first end positioned a first non-zero distance above the interface plane, and a second end disposed a second non-zero distance from a top surface of the second media layer. A backwash fluid line is positioned to inject a backwash fluid into the first filter media, and a backwash gas line is positioned to inject a backwash gas into the draft tube.

摘要： A method of additively manufacturing is provided. The method may include successively depositing and fusing together layers of a superalloy powder mixture comprised of a base material powder and a eutectic powder, to build up an additive portion, which eutectic powder has a solidus temperature lower than the solidus temperature of the base material powder. The method may also include heat treating the additive portion at a temperature greater than 1200° C. to heal cracks and/or fill pores and to homogenize the alloy of which the additive portion is comprised. The additive portion alloy has a chemistry defined by the superalloy powder mixture. The base material powder may be formed of a nickel-base superalloy with an aluminum content by weight of at least 1.5%. The eutectic powder may be a nickel-base alloy including by weight about 6% to about 11% chromium, about 5% to about 9% titanium, and about 9% to about 13% zirconium, with balance nickel as its primary components.

摘要： A computer-implemented method of detecting an anomalous action associated with a physical system includes developing, by a computing device a plurality of vectors, each vector indicative of an event that occurred at a specific time within the system, combining, with the computing device each vector that occurred within a predefined time duration into one of a plurality of master vectors, and performing, with the computing device a cluster analysis to group each master vector of the plurality of master vectors into one of a plurality of states. The method also includes determining, with the computing device a real-time master vector based at least in part on one or more events that occur within the predefined time duration, classifying, with the computing device the real-time master vector as a real-time state, and indicating that the real-time state is anomalous when the real-time state doesn't match one of the plurality of states.

摘要： A nondestructive method for a volumetric examination of a blade root of a turbine blade while the turbine blade is installed in a turbine shaft of a steam turbine includes attaching a bracket to the turbine blade, the bracket conforming to the geometry of the turbine blade, positioning an ultrasonic phased array probe within a slot formed in the bracket to enable the probe to translate along the geometry of the turbine blade to a desired position for generation of a scan of a portion of the blade root, generating a scan of the desired position by directing ultrasonic waves via the ultrasonic phased array probe, and capturing reflected ultrasonic waves by a receiver to generate the scan and comparing the scan to a reference scan of the blade root to determine defects within the blade root.
