The topology mapper includes a discovery module, a memory, and a presentation module. The discovery module is constructed and arranged to discover network elements in a communications network. The memory constructed and arranged to store topology data received from the discovery module. The presentation module constructed and arranged to present data related to topology of the communication network.

A system and method for providing improved adaptive multi-rate wideband (AMR-WB) discontinuous transmission (DTX) synchronization. According to various embodiments, an indication on the start of the inactive speech period is signalled to the decoder via a voice activity detection (VAD) flag a predetermined number of frames before the DTX period will start, i.e., before the SID_FIRST frame is received. When the VAD flag indicates active speech, or when the VAD flag has been set to zero less than the predetermined number of frames ago, the received NO_DATA frame can be classified with a high degree of reliability as active speech, i.e., considered as transmitter, network or terminal-initiated signalling, and can be substituted by a SPEECH_LOST frame. When the VAD flag was set to zero eight frames ago or earlier, the NO_DATA frame is classified as DTX.

The invention discloses a grabbing device for earthwork engineering construction and a working method thereof. The grabbing device includes a frame bottom plate and a mounting plate. The two mounting plates are rectangular parallelepiped and arranged symmetrically. The frame bottom plate is symmetrically arranged on both sides of the bottom of the mounting plate. A reinforced connection mechanism is provided above the mounting plate; the piston rod of the cylindrical cylinder block is connected with a rotating plate passing through the waist-shaped hole through a hinge, and a through hole is opened at the bottom of the rotating plate, and the through hole is interference fit with a rotating shaft. Both ends are fixedly connected with a grabbing mechanism; the grabbing mechanism includes a melon-grabbing swing arm, a melon-grabbing connecting plate, and a melon-grabbing swing arm. The melon-grabbing connecting plate is welded, and the melon-grabbing connecting plate is in the shape of a rectangular plate, and the inner side of the melon-grabbing connecting plate is threadedly connected with several parallel-arranged melons. Working methods include sampling operations and grabbing operations. The grasping device of the present invention has high flexibility, convenient operation, high safety and the function of sampling.

A qP wave reverse time migration method with stable TTI medium, which relates to the technical field of seismic exploration data processing, and its invention content is: based on the existing TTI medium stable qP wave equation, the qP wave equation with regularization term is derived , and then perform adaptive regularization parameter selection: where θ, φ are the dip angle and azimuth angle of the formation, respectively. On the basis of the existing stable qP propagation operator, it adds a regularization term to the qP wave equation, and obtains a more stable qP wave equation without increasing the amount of calculation and storage, so that the TTI medium RTM can adapt to the model Wider performance increases the practicability of the algorithm; the size of the regularization coefficient is automatically determined by using the formation dip and azimuth information without manual intervention, making the regularization equation more robust when dealing with actual data.
