Abstract: The present disclosure relates to an FPGA-based dynamic graph processing method, comprising: where graph mirrors of a dynamic graph that have successive timestamps define an increment therebetween, a pre-processing module dividing the graph mirror having the latter timestamp into at least one path unit in a manner that incremental computing for any vertex only depends on a preorder vertex of that vertex; an FPGA processing module storing at least two said path units into an on-chip memory directly linked to threads in a manner that every thread unit is able to process the path unit independently; the thread unit determining an increment value between the successive timestamps of the preorder vertex while updating a state value of the preorder vertex, and transferring the increment value to a succeeding vertex adjacent to the preorder vertex in a transfer direction determined by the path unit, so as to update the state value of the succeeding vertex.

Abstract: A method and system for cooperative charging between an unmanned aerial vehicle and an unmanned surface vessel includes: using the unmanned aerial vehicle to capture an image of the unmanned surface vessel; analyzing the relative position of a capturing device and the velocity of the unmanned surface vessel; controlling the unmanned aerial vehicle to approach the capturing device, and making the unmanned aerial vehicle to hover at a certain height within the capture range; detecting whether the unmanned aerial vehicle is within the capture range and, if within the range, using the unmanned surface vessel to capture the unmanned aerial vehicle or using the unmanned aerial vehicle to re-capture an image of the unmanned surface vessel; using the capturing device to adjust the position of the unmanned aerial vehicle and performing wireless charging.

Abstract: The present disclosure provides a data storage system, including data cache module, data processing module, and a persistent memory. The data cache module includes an on-chip mapping data cache and an on-chip counter cache, where the mapping data cache is configured to cache mapping data, and when the free space of the mapping data cache is less than a preset threshold, the least recently used mapping data cache line will be evicted from the cache and written back to the persistent memory. The data processing module encrypts/decrypts persistent memory data by using their counters, and accesses the persistent memory blocks indicated by their corresponding mapping data. The persistent memory comprises the first and second storage regions for the latest checkpoint data and modified working data in the current checkpoint interval respectively.
