Abstract: A method for injecting a reductant into an exhaust gas of a power system. The method includes oscillating injections of the reductant between a higher reductant injection rate and a lower reductant injection rate. The higher injection rate is high enough to result in storage of a decomposed form of the reductant on a selective catalytic reduction on-filter (“SCR+F”), and the lower injection rate being low enough to result in depletion of the decomposed form of the reductant on the SCR+F. The SCR+F includes a diesel particular filter and a selective catalytic reduction catalyst applied thereto.

Abstract: A method for injecting a reductant into an exhaust gas of a power system. The method includes injecting the reductant at a commanded flow rate, while simultaneously oscillating a supply pressure of the reductant between a higher supply pressure and a lower supply pressure.

Abstract: A single piece device enables medical clinicians to clean and disinfect both an injection port (needleless I.V. connector) and a vascular access catheter hub. The device has a body with a first end having a blind hole with a wall adapted to be engageable with the threads on the housing of an IV connector and a bottom surface adapted to engage the top surface of the IV connector. The device body has a second end defining a male-luer slip extending out of a recess. The male-luer slip is adapted to extend into a standard vascular access catheter hub such that it engages the inner walls of the catheter hub, and the recess is adapted to receive and be engageable with the outside thread element of the catheter hub.

Abstract: The disclosure relates to a control system for a turbo-charged engine having a variable geometry turbine driving a compressor. An intake manifold temperature sensor senses an intake manifold temperature. An intake manifold pressure sensor senses an intake manifold pressure. A turbine inlet temperature sensor senses a turbine inlet temperature. A turbine inlet pressure sensor senses a turbine inlet pressure. A control unit generates a vane position control signal which is applied to a vane control input of the turbine. The control unit generates the vane position control signal as a function of turbine inlet temperature and turbine inlet pressure.

Abstract: Roughly described, a system enables quick and accurate depiction to a user of multi-patterning layout violations so that they may be corrected manually and in real time, and without interfering with normal manual editing process. In one embodiment, the system involves iteratively building tree structures with nodes identifying islands and arcs identifying multi-patterning spacing violations between the connected islands. The system detects coloring violations during the building of these tree structures, using the relationships previously inserted. The coloring violations preferably are reported to a user in the form of visual indications of the cycles among the candidate spacing violations, with the candidate spacing violations also themselves indicated visually and individually. The user can see intuitively how to move the islands around, and in which directions and by what distance, in order to remove a multi-patterning spacing violation and thereby break the cycle.

Abstract: Popular object requests are handled using a front-end cache, and hashing is applied only to the requests in the stream that were not handled by the front-end cache. A cache (e.g., a web proxy cache) is placed in front of a Level 7 switch and services the popular requests from the cache based on the content of the request (e.g., based on the portion of an HTTP request following the domain name). The remaining requests are hashed and then routed to the back-end server. Requests that make it past the cache are still routed to the back-end server. A Level 4 switch is placed in front of a plurality of web proxy caches, each of which are in turn placed in front of a respective Level 7 switch, each of which are connected to a respective server farm, so that incoming web requests are handled on a round robin basis (or other SLB technique) before being sent to the cache.

Abstract: An improved load balancing method, system, and computer program product handles popular object requests using a front-end cache, and hashing is applied only to the requests in the stream that were not handled by the front-end cache. A cache (e.g., a web proxy cache) is placed in front of a Level 7 switch, such that the cache services the popular requests from the cache based on the content of the request (e.g., based on the portion of an HTTP request following the domain name). The remaining requests are hashed and then routed to the back-end server. This allows the requests that make it past the cache to still be routed to the back-end server and take advantage of the efficiencies provided therefrom.

Abstract: A configuration method includes selecting a design configuration, and modeling the solution configuration having a failure event for the selected solution configuration to determine an amount of down time associated with the failure event. A first penalty cost function is applied the amount of down time to determine a first penalty cost associated with the failure event of the selected solution configuration.

Abstract: An embodiment of a method of designing a storage system begins with a step of assigning decision variables to a range of candidate storage systems. Each of the decision variables identifies a single candidate storage system. The method concludes with a step of employing the decision variables in a mathematical program to determine which of the candidate storage systems meets availability and reliability criteria and incurs a near minimal projected cost.

Abstract: In a computer network system, the caches at individual stations are available to other stations. A central cache directory is maintained at a network server. Each time a station caches a data object received from a remote network, it informs the central cache directory. When a station comes online, it is asked to send a list of the contents of its cache. Whenever a station seeks an object from the remote network, the local network server first checks the central directory cache to see if the request can be satisfied at one of the local stations. Only if it cannot is the requested object retrieved from the remote network.

Abstract: An actuator control loop for controlling head position in a rotating media data storage system. The invention applies the compensation zero to the PES prior to summing it with the integrator. This scheme reduces transients caused by the integrator initialization step because the zero does not "see" the integrator initialization step. Transients that can result from coupling the integrator initialization to the zero can cause overshoot and ringing in the actuator, increasing settling time and reducing system performance. The present invention also provides a first sample velocity compensation scheme that removes the velocity correction factor from the PES signal in the first sample after a seek. This significantly reduces settling time and improves system performance. In one embodiment, the microprocessor of the present invention calculates a velocity compensation factor based on the PES signal. This signal is then superimposed on the integrator output.
