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.

Generate an intrinsic projection matrix (#14) from a learning image population (#10) comprising high-quality images and low-quality image pairs by using projection computation (#12) of local relations to create a projection core tensor (#16), which Projection kernel tensors are used to define the correspondence between low-quality images and intermediate eigenspaces and the correspondence between high-quality images and intermediate eigenspaces. Create (#24) the first sub-kernel tensor from the projection kernel tensor based on the first setting, and project (#30) the input low-quality image (#20) based on the intrinsic projection matrix and the first sub-kernel tensor, to compute the coefficient vector in the intermediate eigenspace. The coefficient vector is projected (#34) based on the second sub-kernel tensor created from the projected kernel tensor by the second setting (#26) and based on the intrinsic projection matrix to obtain a high-quality image (#36). This can realize highly accurate and highly robust (robust) image conversion, which can ease the input condition of an image as a conversion source, and can reduce processing load, can speed up processing, and can suppress required memory size.

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.

A magnet arrangement for generating an NMR-compatible homogeneous permanent magnetic field is described. The invention has two permanent magnets, referred to hereafter as main magnets, which each have a magnet pole surface area. The magnet pole surface areas are situated parallel and at a distance to one another, so that the main magnets define an interspace on both sides through their magnet surface areas. The magnet pole surfaces of the main magnets each have a magnetic polarization opposite to one another. At least two annular permanent magnets are used, which are referred to hereafter as ring magnets, are situated coaxially to one another and jointly radially bound a ring inner chamber. The ring magnets are situated relative to the two main magnets in so that the ring inner chamber at least regionally encloses the interspace, and the magnetic fields of the main and ring magnets are constructively superimposed.
