In this paper, an efficient mining algorithm (denoted as EMAFCI) for frequent closed itemsets in data stream is proposed. The algorithm is based on the sliding window model, and uses a Bit Vector Table (denoted as BVTable) where the transactions and itemsets are recorded by the column and row vectors respectively. The algorithm first builds the BVTable for the first sliding window. Frequent closed itemsets can be detected by pair-test operations on the binary numbers in the table. After building the first BVTable, the algorithm updates the BVTable for each sliding window. The frequent closed itemsets in the sliding window can be identified from the BVTable. Algorithms are also proposed to modify BVTable when adding and deleting a transaction. The experimental results on synthetic and real data sets indicate that the proposed algorithm needs less CPU time and memory than other similar methods. © 2011 ACADEMY PUBLISHER.

The model equation on growing domains is first presented, and the comparison principle is then proved. The asymptotic behavior of temporal solutions to the reaction-diffusion problem is given by constructing upper and lower solutions. Our result shows that when the domain grows slowly, the species successfully spreads to the whole habitat and stabilizes at a positive steady state, while it dies out in the long run if the domain grows fast. Numerical simulations are also presented to illustrate the analytical result. © 2011 Springer Science+Business Media B.V.

Box 211, Amsterdam, 1000 AE, Netherlands Abstract:Electrode with optical shapes is appreciated in microfluidics. In this article, we reported a flexible poly(dimethylsiloxane) (PDMS)-based gold electrode for ascorbic acid detection. Gold nanoparticles were chemically deposited on PDMS and the composite film was applied as working electrode. The electrode could undergo deformation and display good response performance without damage. This biosensor could give quick response to ascorbic acid (AA) (<5. s) and the currents were linear with concentrations of AA in range of 0.023-7.00. mM and 30-100. mM, respectively. Limit of detection was 0.008. mM (S/N = 3). This biosensor has been applied to determine ascorbic acid content in vitamin C tablets and the results were consistent with traditional iodometric method. © 2011 Elsevier B.V.

This paper takes DFIG for an example. In order to protect the rotor side converter, it analyzes DFIG's electromagnetic transition process aroused by different voltage phase angle while the grid voltage drops. A control strategy to eliminate harmonic components during transition process is proposed. Simulation results show that the control strategy can not only achieve the purpose of protecting the rotor side converter, while eliminating the harmonic currents of stator side and rotor side when voltage drops, but also provide reactive power to the power grid.

In order to apply the Agent method to these new areas, a multi-agent system model is built in this paper, and corresponding task schedulable problem and maximum scheduling problem are defined based on this multi-agent system model. Task schedulable problem is modeled using flow network, and it is proved that maximum flow algorithm can be used to solve such problem, which means the problem can be solved in polynomial time. Furthermore, by analyzing the flow network model, a necessary and sufficient condition which can be used to determine whether tasks can be scheduled is gained and proved. Three approximation algorithms have been proposed to solve the maximum scheduling problem. The experiment results show that all above algorithms can get pretty solutions in solving maximum scheduling problem, and the approximation ratio for optimal solution of these approximation algorithms are all larger than or equal to 0.5 even though the resource ratio is very low. © 2011 ACADEMY PUBLISHER.

Issue date:November 2011 Publication year:2011 Pages:1173-1181 Language:English ISSN:00405752 CODEN:THAGA6 Document type:Journal article (JA) Publisher:Springer Verlag, Tiergartenstrasse 17, Heidelberg, D-69121, Germany Abstract:Rice seed size is an important agronomic trait in determining the yield potential, and four seed size related genes (GS3, GW2, qSW5/GW5 and GIF1) have been cloned in rice so far. However, the relationship among these four genes is still unclear, which will impede the process of gene pyramiding breeding program to some extent. To shade light on the relationship of above four genes, gene expression analysis was performed with GS3-RNAi, GW2-RNAi lines and CSSL of qSW5 at the transcriptional level. The results clearly showed that qSW5 and GW2 positively regulate the expression of GS3. Meanwhile, qSW5 can be down-regulated by repression of GW2 transcription. Additionally, GIF1 expression was found to be positively regulated by qSW5 but negatively by GW2 and GS3. Moreover, the allelic effects of qSW5 and GS3 were detailedly characterized based on a natural population consisting of 180 rice cultivars. It was indicated that mutual interactions exist between the two genes, in which, qSW5 affecting seed length is masked by GS3 alleles, and GS3 affecting seed width is masked by qSW5 alleles. These findings provide more insights into the molecular mechanisms underlying seed size development in rice and are likely to be useful for improving rice grain yield. © 2011 Springer-Verlag.
