Dynamic Adjustment of Sliding Windows over Data Streams of adjustment with greedy method and dynamic programming method, which minimize the total error of queries or achieve low memory overhead. The analytical and experimental results show that our algorithms can be applied to the data stream systems efficiently.

The Dimension-Reduced Multi-scale Histogram: A New Method for Fast and Efficient Retrieval of Similaalso presented and based on it, we construct the Slim-tree index structure as the metric access method to answer similarity queries. We also extend it to subsequence matching and presented a MSST index structure.

Spatio-temporal Database with Multi-granularitiesand approximate region, ASTD can process the multiple level data together, perform the query in variant precision and handle uncertainty. Compared with similar systems, ASTD is more powerful in multiple granularities, uncertainty, object type and granularity operations.

A Simple but Effective Dynamic Materialized View Caching we propose a dynamic materialized view management approach with a new hit prediction, which can predict the users’ interest in an ongoing fashion and adapt to changes if necessary. Extensive performance studies show that our approach achieves a high cache hit ratio and speeds up the response time or throughout for different kinds of OLAP queries.

https://doi.org/10.1007/978-3-642-76156-0eneralized constrained sliding window queries and proved that our technique is applicable for flexible window settings. Our performance study indicates that the space required in practice is much less than the given theoretical bound and the algorithm supports high speed data streams.

Identities and Modernities in EuropeCM which allow various client devices to communicate at their best acceptable QoS level through consistent and simple APIs. We present a preliminary prototype of GCM to illustrate its functionalities of communicating with heterogeneous mobile devices by using various communication protocols.
