Manager election for erasure coding groups
To ensure that there is an elected manager among storage nodes of an erasure coding group (“ECG”), an ECG manager (“ECGM”) election process is periodically performed among available storage nodes that are configured with the software to perform the services of an ECGM.

The storage node then selects a PID according to a criterion and elects the storage node corresponding to the selected PID to be the acting ECGM. This process is performed periodically, so even if the acting ECGM storage node fails, a new ECGM is eventually selected from the available storage nodes. |

System and method for handling dependencies in dynamic thread spawning for a multi-threading processor
Aspects of the present disclosure are presented for a multi-threaded system configured to efficiently handle dynamic thread spawning. When a child thread is spawned when executing a program, it may be possible that the parent thread needs the child thread ID for initialization. However, to get the child thread ID, the child thread may need to be generated, and once it is generated, it could be executed immediately, even before the initialization finishes, causing an error. The present disclosure introduces a memory efficient solution through use of a control circuit configured to control when child threads can be executed while still enabling the parent threads to obtain the child thread IDs. |

Apparatus for data processing and a method of data processing are provided, according to which the processing circuitry of the apparatus can access a memory system and execute data processing instructions in one context of multiple contexts which it supports.

Multi-touch object inertia simulation
The inertia system provides a common platform and application-programming interface (API) for applications to extend the input received from various multi-touch hardware devices to simulate real-world behavior of application objects.

Detection of corrosion rates in processing pipes and vessels
For a monitored corrosion sensor, such as a sensor based on one or more mechanical oscillators disposed in a fluid flow, one or more values are measured over time. The values can be measured at a desired frequency, such as a once per second, once per minute, or another convenient frequency. The measured data can then be analyzed as a time series. The goal of the analysis is to identify variations in the time series data that are sufficiently unexpected relative to the prior behavior of the time series within a given time window. The identified variations can then, for example, be excluded from consideration when determining a corrosion-related value for the sensor. |

A component according to an exemplary aspect of the present disclosure includes, among other things, an airfoil that includes a first sidewall and a second sidewall joined together at a leading edge and a trailing edge and extending from a base to a tip. A plenum is defined inside the airfoil. A first cooling cavity merges into the plenum and a second cooling cavity merges into the plenum. A rib extends from at least one of the first sidewall and the second sidewall at least partially into the plenum to separate the first cooling cavity from the second cooling cavity. |

Airfoil and method of fabricating same
A method of fabricating an airfoil includes forming a tip portion and imaging a second end of a body portion to obtain image data of one or more mortises formed therein. One or more tenons are formed on the first end of the tip portion using the image data of the second end of the body portion. The one or more tenons are manufactured using one of additive or subtractive manufacturing techniques. To complete assembly, the first end of the tip portion is positioned relative to the second end of the body portion such that each of the one or more tenons of the tip portion align with and are in sliding engagement with a respective one of the one or more mortises of the body portion. The body portion and the tip portion are coupled together such that the tip portion and the body portion form the airfoil. An airfoil formed by the method is also disclosed. |

Damper groove with strain derivative amplifying pockets
The stiffness of a rotor part is varied over its circumference to allow damper rings to effectively work in high speed applications. Circumferentially spaced-apart pockets may be defined in the rotor to create discontinuous strain to increase the force required to lock the damper ring in the groove above the centrifugal force of the ring when the rotor is rotating. |
