Abstract The threshold proxy re‐encryption (tPRE) algorithm not only ensures the separation of data ownership and use right, but also prevents a single from doing evil. In order to avoid collusion multiple proxies, this paper constructs decentralized crypto network (DCN) based on blockchain technology tPRE. DCN is more than key management system, while expanding storage capacity network. Combin...

a r t i c l e i n f o JEL classification: C23 E44 Q43 Keywords: Crude oil shocks Stock market prices Panel data Asymmetric adjustment Granger causality This paper proposes a panel threshold cointegration approach to investigate the relationship between crude oil shocks and stock markets for the OECD and non-OECD panel from January 1995 to December 2009. Nonlinear cointegration is confirmed for ...

Exports are a crucial driving force of China’s economic growth; however, researchers have yet to verify whether they can effectively improve the high-quality development. Based on interprovincial panel data from 2000 2019, in this study, we constructed development indicator system through entropy weight method, and adopted linear regression model dynamic threshold empirically test export trade ...

This paper investigates the fault detection of a micro parallel plate capacitor subjected to nonlinear electrostatic force. For this end Thau observer, which has good ability in fault detection of nonlinear system has been presented and governing nonlinear dynamic equation of the capacitor has been presented. Upper and lower threshold for fault detection have been obtained. The robustness of th...
