Structure-independent disaster recovery: Concept, architecture and implementationsScience in China Series F: Information Sciences - Tập 52 - Trang 813-823 - 2009
WeiMin Zheng, BinXing Fang
Disaster recovery (DR) techniques ensure the data safety and service continuity under different natural and human-made disasters by constructing a high reliable storage system. Traditional disaster recovery methods are structure-dependent. It is hard to share the DR resources between different DR systems, which made it expensive. We present a structure-independent disaster recovery theory and its ...... hiện toàn bộ
A novel space-borne antenna anti-jamming technique based on immunity genetic algorithm-maximum likelihoodScience in China Series F: Information Sciences - Tập 48 - Trang 397-408 - 2005
Haihong Tao, Jiang Yu, Hongyang Wang, Guisheng Liao
A novel space-borne antenna nulling method is presented on rejecting strong multi-interference from the ground and air. Immune Genetic Algorithm for searching for the multi-extremum of maximum likelihood function has been developed, which is based on injecting vaccine pick-up adaptively. GA has the capability of the whole searching and is not limited by the selection of initial parameter. And the ...... hiện toàn bộ
Solution to the Generalized Champagne Problem on simultaneous stabilization of linear systemsScience in China Series F: Information Sciences - Tập 50 - Trang 719-731 - 2007
Qiang Guan, Long Wang, BiCan Xia, Lu Yang, WenSheng Yu, ZhenBing Zeng
The well-known Generalized Champagne Problem on simultaneous stabilization of linear systems is solved by using complex analysis and Blondel’s technique. We give a complete answer to the open problem proposed by Patel et al., which automatically includes the solution to the original Champagne Problem. Based on the recent development in automated inequality-type theorem proving, a new stabilizing c...... hiện toàn bộ
Challenges of 22 nm and beyond CMOS technologyScience in China Series F: Information Sciences - Tập 52 - Trang 1491-1533 - 2009

It is predicted that CMOS technology will probably enter into 22 nm node around 2012. Scaling of CMOS logic technology from 32 to 22 nm node meets more critical issues and needs some significant changes of the technology, as well as integration of the advanced processes. This paper will review the key processing technologies which can be potentially integrated into 22 nm and beyond technology node...... hiện toàn bộ
Variation-based approach to image segmentationScience in China Series F: Information Sciences - Tập 44 - Trang 259-269 - 2001
Yongping Zhang, Nanning Zheng, Rongchun Zhao
A new approach to image segmentation is presented using a variation framework. Regarding the edge points as interpolating points and minimizing an energy functional to interpolate a smooth threshold surface it carries out the image segmentation. In order to preserve the edge information of the original image in the threshold surface, without unduly sharping the edge of the image, a non-convex ener...... hiện toàn bộ
