Abstract: The present application relates to a technical field of determining an irreversible demagnetization of a grain boundary diffusion NdFeB magnet, and more particularly, to a method for identifying an irreversible demagnetization of a grain boundary diffusion NdFeB magnet by magnetic field distribution. After applying a reverse magnetic field to a saturatedly magnetized grain boundary diffusion NdFeB magnet, if a number of magnetic poles on a non-diffusion face of the grain boundary diffusion NdFeB magnet is increased, it is determined that there is an irreversible demagnetization in the grain boundary diffusion NdFeB magnet.

Abstract: A programmable semiconductor device contains a wireless communication block (“WCB”) capable of facilitating wirelessly field programmable gate array (“FPGA”) programming download as well as functional logic implementation. In one aspect, WCB detects an FPGA access request for initiating an FPGA reconfiguration from a remote system via a wireless communications network. Upon receiving a configuration bitstream for programming the FPGA via the wireless communications network, the configuration bitstream is forwarded from WCB to a configuration download block (“CDB”) for initiating a configuration process. CDB subsequently programs at least a portion of configurable logic blocks (“LBs”) in FPGA in response to the configuration bitstream.

Abstract: A full-face shaft tunnel boring machine system includes a tunnel boring machine cutterhead device for tunneling downwards in a shaft; a full-hydraulic formwork device for supporting and walling in a wellbore; and an upper muck-discharge system for vertically conveying rock mucks generated by tunneling. The tunnel boring machine cutterhead device comprises a vertical guide frame, a cutter-expanded boring head and an advanced cutterhead that are fixedly connected in a vertical order from top to bottom so as to form an integrated structure. The vertical guide frame is a hollow cylindrical structure and driven to rotate around an axis of the vertical guide frame by a power mechanism, and an outer wall of the vertical guide frame is provided with multiple sets of first guide rollers.

Abstract: Disclosed are an interactive information processing method, an electronic device and a storage medium.

Abstract: Embodiments of this application disclose a power control method, and a communication device and system, relating to the field of wireless communication technologies. The method is applied to a first communication apparatus that supports transmission of a plurality of spatial streams. The method includes sending measurement indication information to a second communication apparatus to indicate to the second communication apparatus to perform channel quality measurement on a channel between the first communication apparatus and the second communication apparatus. Each of the plurality of spatial streams occupies a plurality of subbands on the channel. The method further includes receiving a channel quality measurement result fed back by the second communication apparatus, where the channel quality measurement result includes subband measurement information of each subband on the channel.
