It is a challenge to select an optimal set of devices to accomplish a graph-based ubiquitous service and execute it continuously under the circumstances of dynamic environments and limited device capability. We elaborate a Synergy- aware Selection Mechanism (SSM) considering synergetic among devices. In the SSM, we design a distributed algorithm to integrate the devices and a dynamic updating weight method. The simulation results show that SSM can make devices composed together to ensure the continuity and smoothness of service 展开更多

In the early 1980s, to control soil and water loss in the rainy season and problems of water shortages in the dry season in the red soil hilly region of central Jiangxi, the academician team of Li Wenhua from Qianyanzhou Station of the Chinese Academy of Sciences proposed a comprehensive muti-dimensional agriculture development mode known as the “Qianyanzhou Mode”. Since then, models for the forest-livestock-food ecosystem, forest-fruit-economy ecosystem, and land-water compound muti-dimensional system and others have been tested,demonstrated, promoted and used to solve major issues in ecological restoration and agricultural production. With the dawn of the new era, the Qianyanzhou Mode is being given new connotations. In order to reduce the use of pesticides and eliminate the use of antibiotics for improving the quality of agricultural products, increasing farmers’ income, and assisting in strategies for rural vitalization, Qianyanzhou Station is currently focusing on the development of experiments and demonstrations of green agricultural development modes, such as forest-fruit-fowl, hybrid paper mulberry-pig-fruit, grass-sheep(cattle)-fertilizer-fruit, hybrid paper mulberry-fish-goose, paddy-shrimp, and others. The goal of this new effort is to apply the wisdom of Qianyanzhou to the construction of the ecological civilization, including ecological environment protection and the prosperity of farmers in the old revolutionary base areas in central Jiangxi Province. 展开更多

The decreasing feature size makes it harder to make DRAM cells which can keep the current data-holding time. When DRAM cells cannot hold data for a long time, DRAM chips need a more frequent refreshing operation. Therefore, in the near future, time and energy cost on DRAM refreshing will be no longer trivial. In this paper, we propose DRAM Error Correction Pointer(ECP), an error-correction-manner framework, to reduce DRAM refreshes without data loss. We exploit the non-uniform feature of DRAM cells with respect to the data retention time. Compared with the conventional refreshing mechanisms, which refresh DRAM chips by the retention time of the leakiest cells, we refresh the chips much fewer times, and treat the not-in-time refreshed cells as fault elements. We use the structure of ECP as a fault tolerant element. By recording the data which are supposed to be written into the leaky cells in our DRAM-ECP structures, DRAM-ECP can significantly decrease refreshing frequency. When these data are to be read out, DRAM-ECP retrieves the data stored in ECPs and covers them to the corresponding position in the data row. Our experiments show that DRAM-ECP can reduce over 70%refreshing operations than the current refreshing mechanism and also get significant energy saving. 展开更多
