Research on Construction Knowledge Resources Framework of Real Estate Enterprises

<正>Many studies have shown that knowledge resources have been the real source of innovation and competitiveness of real estate enterprises.Therefore,it is the basic work to establish the real estate enterprise knowledge resources framework for implementing knowledge management(KM),and it should be given enough attention.A sort of the real estate enterprise knowledge resources framework system has been built in this paper based on the thought of Clark Henderson' s enterprise knowledge classification,and the contents have been analyzed and expounded.Thus,the real estate enterprises can grasp clearly the basic contents of its knowledge resources,then depict the knowledge system,in the end the solid foundation should be settled for implementing knowledge management.     

Low power and high speed explicit-pulsed double-edge triggered level converting flip-flop

Variable supply voltage-clustered voltage scaling (VS-CVS) scheme can be very effective in reducing power consumption of CMOS circuits without degrading system performance. Level converting flip-flops (LCFFs) are key elements in the CVS scheme. In this paper, a new explicit-pulsed double-edge triggered level converting flip-flop (nEP-DET-LCFF) is proposed, which employs double-edge triggering technique, dynamic structure, explicit pulse generator,conditional discharge technique and proper arrangement of stacked nMOS transistors to efficiently perform latching and level converting functions simultaneously. The proposed nEP-DET-LCFF combines merits of both conventional explicit-LCFFs and implicit-LCFFs. Simulation shows the proposed nEP-DET-LCFF has improvement of 19.2%～46% in delay, and 19.4%～52.9% in power-delay product (PDP) as compared with the published LCFFs.
