Taiwan’s power system is isolated and not supported by other interconnected systems. Consequently, the system frequency immediately reflects changes in the system loads. Pumped storage units are crucial for controlling power frequency. These units provide main or auxiliary capacities, reducing the allocation of frequency-regulating reserve (FRR) and further reducing generation costs in system o...

The research on the pre-collisional tectonic evolution of basin-mountain system at margin Tibetan plateau provides insights into upward and outward growth mechanism in Cenozoic. Lower Jurassic Baitianba Formation quartz-rich conglomerate exposed along edge northwest Sichuan Basin whereas these deposits were incompatible with peripheral carbonatite-dominated orogenic belts, which aroused our gre...

A new chlorogomphid, Chlorogomphus (Orogomphus) auripennis spec. nov. (holotype male; Mt Nankunshan, Longmen County, Guangdong Province, China, 20. V. 2008) is described and illustrated. It is the first species belonging to the subgenus Orogomphus recorded from mainland China. The holotype will be deposited in the Collection of Aquatic Animals, Institute of Hydrobiology, Chinese Academy of Scie...

This paper proposes a framework of multisource geo-knowledge discovery with association rules. Taking into account spatial data exist semantic fuzziness, and the conversion between qualitative concept and quantitative description is uncertain, in our study, conceptual partition algorithm and membership grade judgment algorithm based on cloud model was used. Meanwhile, there are many correlation...
