Implementing a hybrid storage node in a distributed storage system
A new snapshot of a storage volume is created by instructing computing nodes to suppress write requests. Once pending write requests from the computing nodes are completed, storage nodes create a new snapshot for the storage volume by allocating a new segment to the new snapshot and finalizes and performs garbage collection with respect to segments allocated to the previous snapshot. The snapshots may be represented by a storage manager in a hierarchy. Deleted snapshots may be flagged as such in the hierarchy and deletion may be implemented only in memory on a storage node, which is then restored from the hierarchy in the event of a crash. A hybrid storage node may perform both computing and storage services. An IO module determines whether IOPs reference a locally-mounted storage device or a remote storage device. The IO module issues a library call for local IOPs using a shared memory in kernel space. |

Frequency-based detection of chemical expansion dynamics in thin films
Current techniques for measuring chemical expansion in thin film structures are too slow, too imprecise, or require synchrotrons. In contrast, nanoscale electrochemomechanical spectroscopy (NECS) can be used to make nanoscale measurements at time scales of seconds with simple contact or non-contact sensors. In a NECS measurement, a sample, such as thin-film oxide structure, is subjected to a temporally modulated stimulus, such as a sinusoidally alternating voltage. The stimulus causes the sample to expand, contract, deflect, or otherwise deform. A sensor, such as a contact probe or optical sensor, produces an electrical signal in response to this deformation that is correlated with the temporal modulation of the stimulus. Because the stimulus and deformation are correlated, the temporal modulation of the stimulus can be used to filter the deformation signal produced by the sensor, producing a precise, sensitive measurement of the deformation. |

Radial near wall passages are defined between the rib structures and each of the pressure and suction sides of the outer wall. The radial near wall passages are each open to an adjacent central channel along a radial extent of both the near wall passages and the adjacent central channel to define a radial flow pass associated with each central channel. The flow passes are connected in series to form a serpentine cooling path extending in the direction of the chordal axis. |

Magnetic sensor system for detecting abnormal movement in a gas turbine shaft
The present invention relates to a system (100, 300, 400) for detecting abnormal movement of a gas turbine shaft. The system comprises: a magnetic circuit (104, 302, 402) comprising a first magnetic portion (110, 304) and a second portion (112, 404), and including at least one air gap between the first portion and the second portion; and a detection coil (106) wound around the first magnetic portion. The second portion is coupled to or moveable with the shaft to reduce the air gap, on axial movement of the shaft to change the reluctance of the magnetic circuit and thereby induce a voltage in the coil. The system may comprise a controller (108) for shutting off power to the gas turbine when the induced voltage exceeds a threshold voltage. |

Aero-actuated vanes
A turbomachinery vane includes a vane body defining a longitudinal axis, a trunnion extending from the vane body and defining a pivot point for pivoting the vane body about the longitudinal axis, and a lock system operatively connected to the trunnion and configured to lock the vane body in a plurality of locked positions. A gas turbine engine includes a turbomachinery component including a row of actuated stators, wherein the actuated stator row includes a plurality of the turbomachinery vanes. A method of actuating a vane by aerodynamic loads includes moving the vane about a pivot point from a first position to a second position by a first set of by aerodynamic loads. |

Device of a turbomachine for actuating a setting device and turbomachine with such a device
A device of a turbomachine actuates a setting device to vary a flow cross-section of a flow channel of the turbomachine passable by a fluid flow. The device includes a displacement mechanism having an adjustable actuation appliance and couplable with the setting device, and a drive device for displacing the actuation appliance. The displacement mechanism has a centrifugal force appliance displaceable between a basic position and a maximally displaced working position depending on a number of revolutions of the drive device, wherein the actuation appliance is displaceable depending on the position of the centrifugal force appliance with respect to the drive device. A reset device applies a force to the centrifugal force appliance by which the centrifugal force appliance is pressed in the direction of its basic position. |
