In this paper, some properties of the periodic shadowing are presented. It is shown that a homeomorphism has the periodic shadowing property if and only if so does every lift of it to the universal covering space. Also, it is proved that continuous mappings on a compact metric space with the periodic shadowing and the average shadowing property also have the shadowing property and then are chao...

We examine the effects o subscription behavior and wealth transferring controlled by larger shareholders on price discount of private placement. Price discount of private placement and wealth transferring effect exhibits a significant trend when larger shareholders subscribe more private placement shares. Shares proportion subscribed by larger shareholders, shares size of private placement and ...

There has been a great development in Wireless GIS (WGIS) new century. Spatial data transferring and storage in GIS are developed from wired to wireless network. This paper first briefly introduces the technologies and strategies of spatial data transferring and storing in distributed Wireless GIS. Secondly, the schemes of spatial data transferring modes in wireless GIS for improving the networ...

This article studies the control of bidirectional interlink power converters (BILPCs) in hybrid microgrids (HMGs). Here, BILPCs interconnect a dc microgrid to an ac grid-connected HMG. Thanks flatness property differential equations BILPCs, method is able provide desirable output characteristics and robustness against unmodeled dynamics unknown inputs. First, flat models single BILPC parallel-c...
