Through investigating the status of information management of laboratory equipment in a certain aerospace scientific research unit, analyzing the backwardness of its equipment information management mode, low efficiency and high error rate, this paper puts forward the application of RFID(Radio Frequency Identification) technology in the laboratory, combining visualization, data mining technology and...
Frequent closed sequential patterns mining is one of the hot topics in data mining. In this paper, a novel frequent closed sequential pattern mining algorithm, FCSM-PD (frequent closed sequential pattern mining algorithm based on positional data) is proposed, which is the improved BIDE algorithm based on the positional data. The positional data is used to reserve the position information of items...
We consider a consolidation planning problem to a ship in the maritime transportation system, which is a pivotal link to shipping transportation. consolidation planning problem is to select strip coils with different characteristics (ship capacity, destination and due date) and make an outgoing sequence of these coils, which takes the shuffling number into account. In this paper a mixed integer programming...
Concerning the high encoding complexity of low-density parity-check (LDPC) codes, an improved approximately lower triangular (ALT) encoding method is proposed, which is able to take full advantage of the characteristics of the sparse parity-check matrix, such as cyclicity and equality of row weight. Experimental results show that, the proposed method can reduce dramatically the memory requirements...
IEEE 802.11 DCF exhibits poor performance as the number of nodes increases in a wireless LAN due to high collision probability on each transmission. In this paper, based on the optimal constant backoff (OCB) window scheme which fixes the backoff window at every backoff stage, a virtual collision solution (VCS) scheme is proposed to reduce the collision probability and to enhance the throughput performance...
