Estimating product integrals using a composition of warps
Sampling a function is used for many applications, such as rendering images. The challenge is how to select the best samples to minimize computations and produce accurate results. An alternative is to use a larger number of samples that may not be carefully selected in an attempt to increase accuracy. For a function that is an integral, such as functions used to render images, a sample distribution may be computed by inverting the integral. Unfortunately, for many integrals, it is neither easy nor practical to compute the inverted integral. Instead, warp functions may be combined to provide a sample distribution that accurately approximates the factors of the product being integrated. Each warp function approximates an inverted term of the product while accounting for the effects of warp functions approximating other factors in the product. The selected warp functions are customized or “fitted” to implement importance sampling for the approximated product. |

Free world replication protocol for key-value store
The “free world replication protocol” makes use of client computing resources, wherein the clients are not part of the replicated key-value store, but instead reside in the “free world” outside of the dedicated resources of the nodes of the replicated key-value store. In the free world replication protocol, only a single “write” client is authorized to modify the key-value store at any time but any number of clients may be authorized to read data from the key-value store. The write client sends its transactions to multiple nodes in the replicated key-value store. As a result, the latency between the transaction being sent from the client and the transaction being received by the multiple nodes is reduced by comparison to existing protocols in which each client sends transactions to a single node and that node forwards the transactions. A consensus protocol, driven by a master node, is used to periodically ensure consistency, but the data transactions themselves do not make use of a master node. |

The grace-period-start requests are issued on behalf of the callbacks to a combining tree leaf level and propagate toward a combining tree root node. The future-grace-period record is updated in response to grace-period-start requests reaching the root node. The current-grace-period record is updated to start a new SRCU grace period in response to grace-period-start requests reaching the root node if the future SRCU grace period has not completed and there is no SRCU grace period in progress. |

A PCI host bridge (PHB) includes a warm reset mode and a full reset mode. When a fatal error occurs, the type of fatal error is determined, a reset mode corresponding to that type of fatal error is determined, and a reset corresponding to the reset mode is performed.

Quantification of compute performance across multiple independently executed microservices with a state machine supported workflow graph
A bipartite workflow graph, representing an understanding of an overall service, comprises two different graph elements: entities and processes and each individual microservice defines their logical constructs as either an entity or a process in accordance with a universal schema. Notifications from such microservices conform to the universal schema, thereby enabling microservices to individually change how they operate internally, without affecting an understanding of the overall system as represented by the workflow graph. Each graph element has its state maintained by a separately addressable execution unit executing a state machine, which can be individually updated based on information received from the microservices. Changes to the workflow graph are logged and an insight engine monitors such a log to insert insight markers in accordance with predefined events, thereby enabling the collection of metrics on a service wide basis and across multiple microservices. |

Passively controlled inline bleed valves
A bleed valve includes a housing with an inlet coupled to an outlet by a duct. A guide tube is fixed within the housing between the inlet and the outlet. A piston with a piston orifice is slideably supported on the guide tube and movable between an open position and a closed position. The duct fluidly couples the inlet to the outlet in the open position, the duct fluidly separates the inlet from the outlet in the closed position, and the piston orifice fluidly couples the inlet with the outlet in the open position and the closed position to move piston between the open position and the closed position according to differential in pressure between the inlet and the outlet of the bleed valve. Compressors, gas turbine engines, and methods of controlling fluid flow are also described. |

Turbine engine
A gas turbine engine for an aircraft includes an engine core including a turbine, compressor, and core shaft connecting turbine to compressor; a fan located upstream of the engine core and including a plurality of fan blades each having a leading and trailing edge. The turbine includes a lowest pressure turbine stage having a row of rotor blades, each rotor blades extending radially and having a leading and trailing edge. The engine has a fan tip axis that joins a radially outer tip of the leading edge of a fan blade and the radially outer tip of the trailing edge of a rotor blade of the lowest pressure stage. The fan tip axis lies in a longitudinal plane which contains a centreline of engine. A fan axis angle is defined as the angle between fan tip axis and centreline, and is in a range between 10 and 20 degrees. |

Scroll compressor and refrigeration cycle apparatus including fixed scroll baseplate injection port
A first injection port is open to a suction chamber of a plurality of chambers at some rotation phases, and is located within an angular range defined by a line connecting a winding-end contact point of an orbiting scroll at a compression start phase with a base circle center of a fixed scroll and one of two lines tangent to a winding-end point locus of a tip seal at a tooth tip of a spiral body of the orbiting scroll and passing through a base circle center of the orbiting scroll, the one line of the two tangent lines being closer to the winding-end contact point. The first injection port does not interfere with the tip seal at the tooth tip of the spiral body of the orbiting scroll. |

Piston pump, in particular as a pressure generator in an electronically slip-controllable vehicle brake system
A piston pump, in particular as a pressure generator in an electronically slip-controllable vehicle brake system, includes a pump cylinder, a drivable piston, a pump working chamber, a valve space, and a valve. The drivable piston is slidably accommodated in the pump cylinder. The pump working chamber is bounded by the piston and the pump cylinder. The valve controls a supply of pressure medium to the pump working chamber. The valve has a conical valve seat and a closing element having a domed shell section that interacts with the valve seat. The valve seat surrounds the valve space, into which the closing element plunges, at least up to an imaginary center point of the domed shell section, when the valve seat is closed or open. |

Displacement control valve
Provided is A displacement control valve which includes a valve housing, a valve element constituting a main valve that contacts and separates from a main valve seat, for opening and closing communication between discharge ports and control ports by driving force of a solenoid, a pressure-sensitive valve that opens and closes according to ambient pressure, and a pressure-sensitive valve member constituting the pressure-sensitive valve together with a pressure-sensitive element. The valve element and the pressure-sensitive valve member are formed with an intermediate communicating passage which allows communication between the control ports and the suction ports by opening and closing of the pressure-sensitive valve. |

Engine starter and engine starting method
After the vehicle is parked, when the SOC of the auxiliary battery becomes equal to or less than a threshold A, the ECU turns off the switch; when it is predicted that the engine will be started for the first time, the ECU turns on the switch; when the capacitor temperature is equal to or lower than a threshold B, the ECU turns on the heater and starts to charge the capacitor; when the engine is startable and when an engine start operation is performed by the user, the ECU supplies the electric power in the capacitor to the engine starter. |
