To select some "valuable" views for materialization is an essential challenge in OLAP system design. Several techniques proposed previously are not very scalable for systems with a large number of dimensional attributes in the very dynamic OLAP environment. In this paper, we propose two filtering methods. Our first method, the functional dependency filter,(More)
Short sections of text, not to exceed two paragraphs, may be quoted without explicit permission provided that full credit, including © notice, is given to the source. Abstract A divide-and-conquer algorithm for exploiting policy function monotonicity is proposed and analyzed. To compute a discrete problem with n states and n choices, the algorithm requires(More)
Coal logistics plays an important role in the circulation domain of China. A better method of coal logistics warehousing scheduling can accelerate the circulation speed of resources, reduce business costs, and improve business efficiency. In the paper, we propose a framework of coal logistics management information system and analyse relevant functions. We(More)
Since the aging population increasing and the acceleration of the life pace, more intelligent robots have been developed for health monitoring and home security. In this paper, we proposed a framework of indoor security information interactive system basing on Internet and GSM/GPRS hybrid network. On hardware, the system consists of several sub-systems:(More)
Coal is an important fundamental resource. Coal logistics occupies an important position in the circulation domain of China. The construction of Virtual Trade Platform (VTP) for coal enterprises can share resources, accelerate the circulation speed of resources, reduce business costs, and improve business efficiency. By analyzing the characteristics of the(More)
