Antagonistic communities refer to groups of people with opposite tastes, opinions, and factions within a community. Given a set of interactions among people in a community, we develop a novel pattern mining approach to mine a set of antagonistic communities. In particular, based on a set of user-specified thresholds, we extract a set of pairs of communities(More)
—Smart Grid, as one kind of promising sustainable power systems, can rely on two-way communications and emerging smart meters to intelligently control the residential electricity usage. However, due to the inherent open communication media as well as the limited communication, computation and storage capabilities of smart meters, security concerns raise and(More)
PURPOSE To diagnose pneumoconiosis using a computer-aided diagnosis system based on digital chest radiographs. METHODS Lung fields were first extracted by combining the traditional Otsu-threshold method with a morphological reconstruction on digital radiographs (DRs), and then subdivided into six non-overlapping regions (region (a-f)). Twenty-two(More)
— Smart community leverages information and communications technology to improve the quality of life in terms of education, health care, and government services. In smart community, residents manage their home appliances to cooperate on stabilizing renewable power supply, energy saving, and information communications. In this paper, we propose an efficient(More)
The mol-ecule of the title compound, C(14)H(19)N(3)O(7)·0.5H(2)O, exhibits an E conformation about the C=N double bond. The water mol-ecule possesses crystallographically imposed twofold symmetry. In the crystal structure, the mol-ecules are connected by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds into a three-dimensional network.
