    • A fault is located in a transmission line with a sending end, a receiving end, and a tapped load connected to the transmission line at a tap node. The tap node divides the transmission line into a sending side and a receiving side. The sending end and the receiving end each include a measuring device. The fault location is determined by obtaining measured circuit parameters including measured pre-fault and faulted current and voltage values at the sending end and at the receiving end of the transmission line. The phase angle difference due to unsynchronized measurement using the measured pre-fault current and the measured pre-fault voltage values may be calculated. The load impedance of the tapped load is calculated. A first fault location is calculated assuming that the fault is located on the sending side of the tap node. A second fault location is calculated assuming that the fault is located on the receiving side of the tap node. The fault location is selected from one of the first fault location and the second fault location, by selecting the fault location having a value within a predetermined range representing a full distance between two nodes.
    • 故障位于传输线上,发送端,接收端和连接到分接节点处的传输线的抽头负载。 分接节点将传输线划分为发送侧和接收侧。 发送端和接收端各自包括测量装置。 通过获得测量的电路参数来确定故障位置,该电路参数包括传输线的发送端和接收端的测量故障前和故障电流和电压值。 可以计算使用测量的故障前电流和测量的故障前电压值的不同步测量的相位角差。 计算抽头载荷的负载阻抗。 假设故障位于分接节点的发送侧,则计算第一故障位置。 假设故障位于分接节点的接收侧,则计算第二个故障位置。 通过选择具有表示两个节点之间的全距离的预定范围内的值的故障位置,从第一故障位置和第二故障位置中选择故障位置。

    • A method for filtering a malicious call completion indicator in a CCBS service is provided, in which a calling-side network device rejects the current call request or removes the call completion indicator information from the call request and then forwards the call request, when determining the call request carries the information. The disclosure also provides a corresponding apparatus, which includes a reception unit configured to receive a call request, a detection unit configured to detect the call request and to trigger the rejection unit when determining that the call request carries call completion indicator information and a rejection unit configured to reject the current call request. A calling-side network device is also provided. According to the disclosure, the sequence for accessing the calls from calling subscribers to a called subscriber is well kept, thus assuring fairness of the call access and avoiding preferential call access of malicious subscribers.
    • 提供了一种用于过滤CCBS业务中的恶意呼叫完成指示符的方法,其中主叫侧网络设备拒绝当前呼叫请求或从呼叫请求中删除呼叫完成指示符信息,然后在确定呼叫请求时转发呼叫请求 呼叫请求携带信息。 本公开还提供了一种对应的装置,其包括被配置为接收呼叫请求的接收单元,被配置为检测呼叫请求并在确定呼叫请求携带呼叫完成指示符信息时触发拒绝单元的检测单元,以及拒绝单元 配置为拒绝当前呼叫请求。 还提供了呼叫侧网络设备。 根据本公开,用于从主叫用户接入被叫用户的呼叫顺序保持良好,从而确保呼叫接入的公平性,避免恶意用户的优先呼叫接入。

    • Upon extraction of a human figure region in an image, a face or facial part is detected in the image, and an estimated region which is estimated to include the human figure region is determined from position information of the detected face or facial part. The human figure region is extracted in the estimated region. Judgment is made as to whether at least a portion of the human figure region exists in an outline periphery region of the estimated region, and the estimated region is extended and updated so as to include a near outer region near the human figure region in the outline periphery region and outside the estimated region, in the case where a result of the judgment is affirmative. The human figure region is extracted in the extended and updated estimated region.
