Transactional replicator
A transactional replicator applying group commit and barrier concepts is disclosed. Group commit means that the transactional replicator commits multiple transactions in a group and is not restricted to committing single transactions one-at-a-time and is not limited to operating on a single state provider.

All state providers must apply their transactions and update state before additional transactions will be committed. A quorum acknowledgement “unlocks” any locks that were acquired to update the state within a state provider. However, as long as there are no lock conflicts, additional transactions can continue to create new group commits as necessary. |

Fair high-throughput locking for expedited grace periods
An updater needing an expedited RCU grace period may initiate a leaf-to-root traversal of a funnel lock embodied as a hierarchical tree of nodes. For each accessed node, the updater may check an indicator to determine if another updater needing the same expedited grace period has visited the node.

If false, the updater may set the indicator to indicate it has visited the node, and then continue to a next node. If the updater reaches the root node with no indication that any other updater needing the expedited RCU grace period has visited the nodes accessed by the updater, the updater may, while holding a mutex lock, start a new expedited RCU grace period and at the end thereof wake up other updaters waiting on the expedited RCU grace period. |

Air quantity calculation device for internal combustion engine
An ECU calculates a cylinder flowing air amount based on an intake tube pressure, using an air intake valve model simulating a behavior of air flowing into a combustion chamber via an air intake valve. The ECU calculates an air intake amount based on a detection result of an air amount detection sensor, and determines whether the air intake amount matches an actual amount of air flowing into the combustion chamber. When the air intake amount is determined to match the actual amount, the ECU calculates a learnt value based on comparison of the cylinder flowing air amount with the air intake amount. |

Gas turbine exhaust having reduced jet noise
A nacelle exhaust nozzle having a deployable noise-reducing component is described. The noise-reducing component includes an annular perforated sleeve coinciding with the inner nacelle loft line and circumscribing a mixed exhaust gas flow exiting the nacelle. The annular perforated sleeve is radially spaced apart from of a displaceable wall of an inflatable envelope that is displaceable between a deployed position, wherein noise-reduction is active, and a retracted position, wherein noise-reduction is inactive. When the inflatable envelope is pressurized, portions of the displaceable wall project through openings in the perforated sleeve and into the exhaust gas flow to form a rough surface at the loft line which causes a reduction in noise level. The portions of the displaceable wall that project through the openings in the perforated sleeve when the inflatable enveloped is pressurized include a plurality of dimples formed on the inner wall and forming the rough surface. |
