摘要： There is described a method of monitoring a peer-to-peer network. The method comprises: (i) monitoring network traffic between a first peer and the peer-to-peer network so as to identify a first subset of peers in the peer-to-peer network; and (ii) preventing the first peer from communicating with at least one peer in the first subset of peers to thereby cause the first peer to communicate with at least one further peer in the peer-to-peer network so as to enable identification of the at least one further peer. In addition, there is described a peer-to-peer network monitor for monitoring a peer-to-peer network, wherein the monitor is operable to monitor network traffic between a first peer and the peer-to-peer network so as to identify a subset of peers in the peer-to-peer network in communication with the first peer, and wherein the monitor is operable to prevent the first peer from communicating with at least one peer in the subset of peers to thereby cause the first peer to communicate with at least one further peer in the peer-to-peer network so as to enable the monitor to identify the at least one further peer. Corresponding computer programs and computer-readable media are also described.

摘要： Embodiments of this application provide a data transmission method and apparatus and a storage medium. The method includes: After obtaining a first identifier and a second identifier that uniquely identify a first device, the first device scrambles, by using the first identifier, checked data obtained through CRC check. After performing channel coding on to-be-transmitted data and scrambled checked data, the first device scrambles, by using the second identifier, coded data obtained through channel coding, and finally sends scrambled data. In this way, after receiving the scrambled data, a second device may perform descrambling by using the second identifier, and then perform CRC check, to determine whether the received data is correct and determine the first identifier of the first device.

摘要： A micro-region semi-solid additive manufacturing method is provided, where rod-shaped materials are used as consumables, and front ends of the consumables are heated by means of high-energy beam, an electric arc, a resistance heat, or the like, to enable the front ends to be in a semi-solid state in which the solid-liquid two phases coexist; at the same time, the rotational torsion and the axial thrust are applied to the consumables to perform shearing, agitation and extrusion on the semi-solid front ends, that is, the mold-free semi-solid rheoforming is performed. The consumable is transmitted to the bottom layer metal continuously in this manner to form metallurgical bonding, the stacking process is repeated according to a planned route obtained after discretization slicing treatment, and then an object or a stack layer in a special shape can be formed.

摘要： A downlink scheduling data monitoring method, a downlink scheduling data sending method, and an apparatus are provided. The method includes: starting a timer; and after it is determined that the timer expires, monitoring, by using a first discontinuous reception DRX monitoring cycle, downlink scheduling data sent by a base station, where duration of the first DRX monitoring cycle is in a unit of minute or hour. After it is determined that the timer expires, the downlink scheduling data is monitored by using the first DRX monitoring cycle whose duration is in a unit of minute or hour. In this way, not only power consumption is reduced, but also the downlink scheduling data can be monitored.

摘要： The present invention discloses a method, an apparatus, and a system for implementing video quality assessment. When video quality is assessed, a proportion of a damaged data caused by packet loss in a video frame in which the damaged data is located is considered, and other factors are also considered, such as a position of the damaged data in the video frame and impact of a scene in which the video frame is located on the video frame or a video frame located after the video frame. Therefore, accuracy of quality assessment is higher.

摘要： Systems, methods, and storage media for determining the probability of cyber risk-related loss within one or more computing systems composed of computing elements are disclosed. Exemplary implementations may: assess vulnerability by determining an exposure window for a computing element based on the number of discrete times within a given time frame where the computing element is in a vulnerable state; determine a frequency of contact of the computing element with threat actors; normalize the exposure window and the frequency of contact; calculate a threat event frequency by dividing the normalized exposure window by the normalized frequency of contact; and repeat the steps for multiple elements. When combined with liability data that describes the loss magnitude implications of these events, organizations can prioritize the elements based on loss exposure and take action to prevent loss exposure.
