  • Publication number: 20250200005
    Abstract: There is provided a method and apparatus for free space management in a distributed database. Each datanode of the database is assigned a free space map to manage free space. When a datanode requires additional storage space, a new free space map may be assigned to the datanode, a free space map of a different datanode may be shared with the datanode, or a free space map of a different datanode may be reassigned to the datanode. A background process may be used to recycle inactive free space maps.

  • Patent number: 12032592
    Abstract: Methods, systems, and computer-readable media are described in which WAL records are replayed serially at the database sub-object level, thereby enabling parallelism for processes affecting a single database object without interfering with the consistency required to maintain ROS capability. WAL records are replayed serially at the B-Tree branch level, instead of existing approaches which serialize WAL record replay at the object or block level. Described examples may thereby enable multi-block operations (e.g., SPLIT) within the same B-Tree branch to be replayed in the correct sequence, thereby maintaining consistent reads during ROS. Multi-level dispatching at the object and sub-object levels may be used to minimize delays caused by operations affecting multiple branches of a database object.

  • Patent number: 9727057
    Abstract: A method of maintaining positioning between vessels includes monitoring a relative position between a storage tank vessel and a shuttle tanker with a control system in operative communication with the vessels. Also included is inputting physical property data relating to the storage tank vessel and the shuttle tanker to the control system. Further included is processing environmental condition data with the control system. Yet further included is controlling at least one positioning action to be taken by the storage tank vessel and the shuttle tanker with the control system in response to positioning calculations conducted by the control system based on the physical property data and the environmental condition data. Also included is maintaining an angular differential within a predetermined limit with the at least one positioning action.

  • Patent number: 9194369
    Abstract: A wind turbine rotor blade is equipped with an air chamber and equipped via the air chamber to route a modulation beam out of the rotor blade such that the air current along the rotor blade is changed. Thereby the laminar current is changed into a turbulent current on the one hand and its detachment and on the other hand its recreation is achieved in order to produce the laminar current. The control may occur via electrostatic actuators via a learnable control strategy based on neural forecasts, which take the complexity of the non-linear system into account and allow for the plurality of influencing factors. The stress on the rotor blades may be reduced, resulting in longer service life and reduced maintenance costs, a higher level of efficiency or quieter operation.
