With the advantages of flexible parking locations and convenient cycling, Dockless Bicycle-sharing (DBS) has become increasingly popular worldwide. However, with massive increase DBSs electric fences, DBS systems face several challenges: (1) hardness identifying tidal zones; (2) difficulty accurately evaluating overload fences; (3) issues rebalancing in time. To deal these challenges, we propos...

We present a new parallel repartitioning algorithm for adaptive finite-element meshes that significantly reduces the amount of data that needs to move between processors in order to rebalance a workload after mesh adaptation (refinement or coarsening). These results derive their importance from the fact that the time to migrate data can be a large fraction of the total time for the parallel ada...

Despite the US official statement that purpose of its pivot to Asia is rebalance foreign policy towards Asia, it also known aimed for “rebalance” growing China's power in economy and military. Prospectively, aims create a more balanced economy, security diplomacy. However, risks creating Chinese perceptions suspicions lead competitive acquisition position “superpower” region, especially economy...

This paper demonstrates that the imbalanced data sets have a negative effect on the performance of LDA theoretically. This theoretical analysis is confirmed by the experimental results: using several sampling methods to rebalance the imbalanced data sets, it is found that the performances of LDA on balanced data sets are superior to those of LDA on imbalanced data sets. 2006 Pattern Recognition...

 After a relatively widespread global slump, the outlook now varies greatly across world regions. Demand remains weak especially in those world regions where net savings are adjusting in such a way to rebalance external deficits. Against this background, the EU and the euro area itself cannot be considered as homogenous areas because some countries (“the center”) record external surpluses and ...
