Rate-optimized congestion management
This disclosure provides methods and systems for reducing congestion in RoCEv2 networks. The method is configured to operate large-scale in data centers on traffic flowing from a sender node to a receiver node. The method described has three stages: a fast start stage, a transition stage, and a regulation stage. In the fast start stage, the sender sends data to the receiver at a fast initial rate. This may continue until the receiver observes a congestion event. When this happens, the sender reduces the data transfer rate as the method enters the transition stage. From a reduced rate, the method enters the regulation stage, where the rate is increased using a combination of a feedback control loop and an additive increase multiplicative decrease (AIMD) algorithm. |

Security and safety configurations for drone delivery
Embodiments described herein disclose methods and systems for community item distribution. In some implementations, the community item distribution system includes a platform for users to post information regarding items they want to share with the community. The community item distribution system can categorize the information and establish donation parameters for the shared items. The donation parameters can include where and when items can be donated or retrieved, what types of items can be donated, and who can request the donated items. In some cases, the community item distribution system can generate a user interface listing the available items that users can request. Upon request of an item, the community item distribution system can schedule a drone to transport the item, in a secured container with ultraviolet lights to disinfect the item, from the storage location to the delivery location. |

Managing geospatial boundaries
Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for managing geospatial boundaries. In some implementations, an identification of a user is scanned. Based on the scan, information corresponding to the user is retrieved. The user is then registered using the retrieved information corresponding to the user. Location data is obtained. A determination is made that the user is proximate to a geographic boundary. The location data and at least a portion of the information corresponding to the user is transmitted to an access control system. |

Method of controlling an electronic safe lock
A method of controlling an electronic safe lock (1) with an electronic unit (2) of the lock (1) and with an electronic remote control unit (3) wherein the blocking mode of the lock (1) unlocking is activable/deactivable from the remote controller (4), when an blocking signal (21)/remote unblocking signal (22) is generated in the remote controller (4) and this signal is transmitted via the electronic remote control unit (3) to the electronic unit (2) of the lock (1), where it blocks/unblocks the unlocking of the lock (1). Wherein in the blocking mode of the lock (1) unlocking, the lock (1) can also be unlocked from the local controller (5) by generating a local unblocking signal (23) and transmitting it to the electronic unit (2) of the lock (1), where it cancels the effect of the blocking signal (21). Subsequently, the internal unlocking signal is activated. |

Center, update management method, and non-transitory storage medium
A center, configured to communicate over a network with a predetermined server and an OTA master installed in a vehicle, includes a processor. The processor is configured to determine whether a command is transmittable from the center to the OTA master based on communication means information. The processor is configured to transmit, when the processor determines that the command is transmittable from the center to the OTA master, the command to the OTA master using communication means defined in the communication means information. The processor is configured to transmit, when the processor determines that the command is not transmittable from the center to the OTA master, request data to the OEM server. The request data is data for commissioning the OEM server to transmit the enabling command. |

Information processing apparatus, information processing method, and non-transitory computer readable medium
An embodiment of the present invention provides an information processing apparatus that is capable of generating information about contents of a written work more accurately than conventionally possible. The information processing apparatus includes a determination device, a selector, and a generator. The determination device determines whether a first object and a first property that are mentioned in a first electronic document and that are estimated to be in an association relationship are in accordance with a definition of the association relationship between an object and a property. In a case where the first object and the first property are determined to be not in accordance with the definition, the selector selects, instead of the first object, a second object that is in the association relationship with the first property. The generator generates relationship information indicating that the first electronic document is related to the second object. |

Document lineage management system
In some implementations, a system may obtain document lineage training data associated with a plurality of historical documents and corresponding lineage data of independent historical documents of the plurality of historical documents. The system may train, based on the document lineage training data, a lineage analysis model to determine a lineage of edited sections of a source document. The system may receive a plurality of document files that correspond to a plurality of versions of a document. The system may determine, using a similarity analysis model, that a first section from a first version of the plurality of versions corresponds to a second section from a second version of the plurality of versions. The system may determine, using the lineage analysis model, a lineage of a corresponding section of the document that is associated with the first section and the second section. |

Vehicle control apparatus
A vehicle control automatically distinguishes between a moving body and a stationary body, reduces user's operation process, and reduces burdens to shorten time for a parking process. Obstruction points are grouped so as to be divided between obstructions, coloring of moving and stationary bodies are changed for each obstruction, and it is determined whether there is an obstruction for which the coloring has not been changed. If there is an obstruction for which the coloring has not been changed, whether there is license plate information and whether the obstruction is a moving body or a stationary body are determined, and a moving body is changed to red and a stationary body to blue. A display device displays the obstruction information distinguished between stationary or moving objects, and a message to the user such as “obstruction stored” notifies the user of completion of the distinction of the obstruction types. |
