We improve data access efficiency in mobile cloud storage by exploring users' context information. Specifically, we optimize data reading and writing on mobile devices from/to distributed cloud storage according to network condition, user mobility pattern, and data access preference. We propose a Reed-Solomon erasure code based context-aware distributed storage system. Then, a mixed integer linear...
It is educed that synchronously considering the accuracy and stability of prediction model is the primary reason that the linear fixed weight combination prediction model based on minimizing error sum of squares is widely applied to differently domanial prediction problems now by analyzing. On this base, the linear fixed weight combination prediction model based on prediction model validity is built,...
In this paper we describe a methodology and an automatic procedure for inferring accurate and easily understandable expert-system-like rules from forensic data. This methodology is based on the fuzzy set theory. The algorithms we used are described in detail, and were tested on forensic data sets. We also present in detail some examples, which are representative for the obtained results.
The transfer hub plays important role in urban public transit. The level of transfer capacity of transfer hub has great impact on the total operation state of urban transit system. Moreover, pedestrian facilities design principles and passenger management methods don't attach the widespread attentions comparing with other issue in many underground transfer hubs. At present, more pursuers have focused...
