Abstract: Selective catalytic reduction (SCR) systems are known and are generally included in the exhaust systems of diesel engines in order to treat the exhaust gases of such engines. Such systems typically involve the introduction of a diesel exhaust fluid (DEF) into exhaust gas flowing in an exhaust passage of an engine. DEF dosing systems are limited by the amounts of DEF that can be delivered without deposits forming on surfaces of the aftertreatment system. A numerical model of a hydrolysis catalyst is provided. The model comprises a spatial model of a hydrolysis catalyst to be modelled, where the hydrolysis catalyst is divided into a plurality of discrete spatial units. For each of the discrete spatial units, values for a plurality of matter state parameters are determined.

Abstract: A rail assembly includes a track assembly with a retaining lip and a carriage assembly that is received within the track assembly. The carriage assembly includes a body portion, an exterior surface of the body portion, and a retaining bracket fastened to the exterior surface. The retaining bracket extends outwardly from the point at which the retaining bracket is fastened to the exterior surface. The retaining bracket defines a notch that receives the retaining lip of the track assembly.

Abstract: Methods and systems for identifying optimized ablation targets for treating and preventing arrhythmias sustained by reentrant circuits are described. The methods comprise receiving at least one mesh generated from one or more images of a patient's heart, receiving activation data generated from one or more simulations of electrical-signal propagation over the at least one mesh, generating at least one flow graph based on the activation data and the at least one mesh, and applying a max-flow min-cut algorithm to the at least one flow graph to determine at least one of a number, one or more dimensions, and one or more locations of one or more ablation targets.

Abstract: A method of operating a steering system having a rotatable steering control, a steering actuator having a rod movable along a range of travel, a rotary device coupled to the steering control, and a valve assembly disposed between the rotary device and the steering actuator includes rotating the steering control in a first direction, displacing the rod toward an end of the range of travel, and determining when the rod reaches the end of the range of travel. The method also includes, after determining, actuating the valve assembly from a first position in which the rotary device is not in fluid communication with the steering actuator, to a second position in which the rotary device is in fluid communication with the steering actuator, and inhibiting further rotation of the steering control in the first direction due to back pressure on the rotary device.

Abstract: The present disclosure relates to a photocrosslinkable fluoropolymer coating composition, a coating layer comprising a photocrosslinked fluoropolymer and a process for forming the coating layer. Coating layers comprising the crosslinked fluoropolymer have low dielectric constants, low water absorptivity, good adhesion to conventional electronic device substrates, and are able to be photoimaged so as to provide the very fine features needed for modern electronic devices.

Abstract: A steering system includes a user-manipulable steering control, a steering actuator, a pump, and a first valve assembly configured to control a flow of fluid from the pump to the steering actuator in response to manipulation of the steering control. The steering system also includes a rotary device coupled to the steering control. The rotary device is configured to direct fluid in response to manipulation of the steering control. The steering system further includes a second valve assembly movable between a first position in which the rotary device is not in fluid communication with the steering actuator and a second position in which the second valve assembly fluidly communicates the rotary device with the steering actuator.

Abstract: Compliant bellow seal may be axially disposed between first and second cooling plates bounding first and second cooling passages between cooling plates and first and second stage disks in turbine. Bellow seal includes two or more convolutions with oppositely facing forward and aft sealing surfaces, which may be flat, on forward and aft annular sealing walls and cylindrical annular outer and inner contact and sealing surfaces on and facing radially outwardly or inwardly from one of the convolutions. A snake bellow seal embodiment may have at least two of the convolutions being full convolutions of unequal width and a forwardmost partial convolution including the sealing wall. Bellow seal may allow turbine cooling flow from an inter-stage radial face spline to flow through inner openings of second cooling passage and block first stage disk cooling air from flowing through inner openings of first cooling passage.

Abstract: The system enables a data processing framework that polls for files using a listener, controls the workflow using event driven logic, processes financial transactions, and creates a business to business trading partner network. The listener ensures the reliability and data integrity of input files and performs archiving functions. The payment management functions automatically processes transactions, including payor (e.g., the buyer) initiated payments to a payee (e.g., a supplier) by utilizing a flexible, decoupled processing architecture. A payment management computer identifies a universal identifier for each entity and forms relationships and hierarchies in order to increase efficiency of the trading partner network. Metadata describes the format, validation and relationships for a wide variety of financial account data.
