Abstract: A network configuration method includes establishing wireless connection with n second image-forming apparatuses, where n is an integer greater than or equal to 1; updating a connection state information table pre-stored according to the wireless connection established with the n second image-forming apparatuses; based on the updated connection state information table, determining m image-forming apparatuses to-be-connected-to-network, where m is an integer greater than or equal to 0; and sending network connection information for connecting a local area network to the m image-forming apparatuses to-be-connected-to-network, such that the m image-forming apparatuses to-be-connected-to-network are connected to the local area network according to the network connection information. The solutions in embodiments of the present disclosure simplify network connection configuration operations of the image-forming apparatuses.

Abstract: The present disclosure relates to a method and system for improving solid-liquid separation performance of sludge by in-situ crystallization of water. The method comprises the following steps: adding sludge into a pressure vessel, intermittently introducing high-pressure carbon dioxide at a low-temperature condition to generate a carbon dioxide hydrate until a partial pressure of the carbon dioxide is stable, releasing the pressure, and stirring the sludge until no gas escapes, thus obtaining the treated sludge. Compared with the prior art, the method and system provided by the present disclosure are simple and easy to implement, has no consumption of sludge dewatering conditioning agents, and can achieve the recycling of carbon dioxide.

Abstract: The present disclosure provides a data storage control method, an electronic device, and a storage medium. The data storage control method includes obtaining lifespans of a plurality of memory blocks in a flash memory and selecting at least one target memory block according to the lifespans of the plurality of memory blocks, where the at least one target memory block is configured to store data to-be-written; determining a limit storage block with a shortest lifespan in the at least one target memory block; and outputting first prompt information according to the limit storage block and/or a lifespan of at least one memory block, where the first prompt information is configured to prompt lifespan information of the flash memory.

Abstract: The disclosed embodiments provide an absorptive coupled-line bandpass filter. This bandpass filter includes a first port, which is coupled to a first absorptive stub, and a second port, which is coupled to a second absorptive stub. The bandpass filter also includes a coupled-line bandpass section coupled between the first and second ports, wherein the coupled-line bandpass section comprises a set of one or more parallel strip line resonators, which are coupled together in series and are coupled to the first and second ports through overlapping coupled-line sections, wherein at a center frequency of a passband for the absorptive coupled-line bandpass filter, the first and second absorptive stubs appear as open circuits, and outside of the passband, the first and second absorptive stubs appear as matched loads to ground and contribute to absorption of out-of-band signals.

Abstract: A systematic distributed storage system (DSS) comprising: a plurality of storage nodes, wherein each storage node configures to store a plurality of sub blocks of a data file and a plurality of coded blocks, a set of repair pairs for each of the storage nodes, wherein the system is configured to use the respective repair pair of storage nodes to repair a lost or damaged sub block or coded block on a given storage node. Also a distributed storage system DSS comprising h non-empty nodes, and data stored non homogenously across the non-empty nodes according to the storing codes (n,k). Further a method for determining linear erasure codes with local repairability comprising: selecting two or more coding parameters including r and ?; determining if an optimal [n, k, d] code having all-symbol (r, ?)-locality (“(r, ?)a”) exists for the selected r, ?; and if the optimal (r, ?)a code exists performing a local repairable code using the optimal (r, ?)a code.
