A non-linear mapping function generates a first tone-mapped signal by mapping the intensity of the input signal from the reference dynamic range into the target dynamic range. The intensity (I) component of the first tone-mapped signal is sharpened to preserve details, and the saturation of the color (P and T) components is adjusted to generate a second tone-mapped output image. A color gamut mapping function is applied to the second tone-mapped output image to generate an image suitable for display onto the target display. The display management pipeline may also be adapted to adjust the intensity and color components of the displayed image according to specially defined display modes.

Reductions in churn for assigning identifiers to entities in a knowledge graph enables several improvements to the functionality of the computing devices maintaining or accessing knowledge graphs. As the aliases or other terms used to identify a given entity change in response to updates to the knowledge graph, the identifiers assigned to various entities may change. For example, two individual entities conflated as one node may be split into two or two nodes merged into one in response to an update, and existing identifiers should be used to reduce churn. To select the existing identifiers to assign to a given updated entity, the aliases are clustered with the updated entities and the unique modal prior identifier is assigned as the identifier for the updated entity. Higher orders of modality are used to ensure as many existing identifiers are used before creating new identifiers.

A CTS nozzle achieves the object of reducing rubber chips produced when the CTS nozzle is inserted into and extracted from a rubber plug of a sample container during dispensing of a sample, thereby inhibiting the wear of the tip of the CTS nozzle. The CTS nozzle has two cut surfaces at its tip, and the pressure applied from the rubber when the nozzle is inserted into the rubber plug is dispersed onto the two cut surfaces without being deflected onto one of the cut surfaces. The pressure applied to the nozzle due to the resilience of the rubber being pushed away by the nozzle is thus dispersed and the rubber chips produced by the friction between the cut surfaces of the nozzle and the rubber are reduced.

The described embodiments result in a fan air valve having a closed flow area that is not much larger than the closed flow area of a valve having a perpendicular plate. The described embodiments avert compression of perimeter ice on a downstream edge of the plate during modulation without requiring software adjustments to address perimeter ice.

A seal assembly for a turbine engine is disclosed and includes a fixed housing including an axial surface defining an inner diameter and an annular seal that is disposed within the housing and seal against a radial surface of the fixed housing. The annular seal includes a first surface transverse to an axis of rotation and a second surface parallel to the axis of rotation defining an inner periphery. The first surface includes a first notch spaced apart from the inner periphery and overlapping the inner diameter of the fixed housing.

A method optimizing a composite material blade profile for a rotor wheel of a turbine engine, and a blade including a tang compensated by the method. The method includes: compensating a blade airfoil by subdividing the airfoil into slices, and for each airfoil slice and a predetermined rotation speed of a disk of the wheel, calculating centrifugal force applied to the slice, calculating an aerodynamic force moment acting on a bottom section of the slice, and calculating shift values to be applied to a center of gravity of the slice to cancel the aerodynamic force moment; and compensating the blade tang by calculating centrifugal force applied to a blade portion situated beyond the airfoil neck, calculating an aerodynamic force moment acting on a bottom section of the blade tang, and calculating shift values to be applied to a center of gravity of the blade tang to cancel the aerodynamic force moment.

A gas turbine engine component has an engine component body and at least one hole formed within the engine component body and extends between a hole inlet and a hole outlet. The hole has a first portion with a first roughness and a second portion having a second roughness that is less than the first roughness. The first portion is upstream of the second portion. A gas turbine engine and a method of forming a cooling hole are also disclosed.

A thrust balancing mechanism for balancing axial loads on a rotor thrust bearing 3 is described. The mechanism comprises a piston arrangement 6 axially mounted on a stationary structure 2, about a center axis arranged, in use, in coaxial alignment with a rotating shaft 1 carrying the rotor thrust bearing 3. A hydrodynamic thrust bearing 8 is mounted, in use, between the piston 6 and the rotor thrust bearing 3. The piston 6 is pressurized so as to impart to the rotor thrust bearing 3, via the hydrodynamic thrust bearing 8, an axial load which counters an axial load imparted to the rotor thrust bearing 3 by the rotating shaft 1.

A bottom hole assembly includes a single wire bus, a legacy sensor coupled to the single wire bus, and at least one high frequency communication sensor coupled to the single wire bus. The high frequency communication sensor injects a high frequency signal alternating between high frequency synchronization pulses and high frequency data signals onto the single wire bus. A first high frequency pass filter coupled between the at least one high frequency communication sensor and the single wire bus is also included. The high frequency pass filter passes the high frequency signal to the single wire bus from the high frequency communication sensor. The bottom hole assembly includes a first high frequency blocking filter coupled between the legacy sensor and the single wire bus. The high frequency blocking filter blocks the high frequency signal from the high frequency communication sensor from disturbing a legacy signal at the legacy sensor.

A wire cross-sectional shape for a wire wrap screen provides a primary and secondary gap with a contained circumferential volume in between. The secondary gap extends screen life by taking the place of the primary gap if erosion opens the primary gap and lets the larger solids get past. The closed space between the primary and secondary gaps also has the effect of reducing velocity due to the enlarged volume before the secondary gap is reached while also creating turbulence between the gaps to slow the fluid velocity to protect the secondary gap. All or parts of the wire outer surface can optionally be coated to extend service life.

An apparatus that is usable with a well includes an inner ring, an outer ring and a tool assembly. The inner ring includes a seat to receive an untethered object; the outer ring is concentric with the inner ring; and the tool assembly, downhole in the well, engages the outer ring with the inner ring to press the outer ring into a wall of a tubing string to secure the outer ring to the tubing string.
