Interception of a hypersonic vehicle by low-speed interceptors: novel perspectives and cost optimisation by Shuangxi Liu, Shijun Liu, Binbin Yan, Tong Zhang, Xu Zhang, Jie Yan

“…The conditions for accurately intercepting hypersonic vehicles by low-speed interceptors in the terminal guidance process are examined, considering the general form of a guidance scheme. First, based on the concept of the engagement geometry, three interception scenarios are established considering different manoeuvring configurations of the interceptors and hypersonic vehicle. …”

Fractional-Order Sliding Mode Guidance Law for Intercepting Hypersonic Vehicles by Shuangxi Liu, Binbin Yan, Xu Zhang, Wei Liu, Jie Yan

“…This paper addresses the problem of a low-speed missile intercepting a hypersonic vehicle in the longitudinal plane. Firstly, based on the concept of the zero of the angular rate of the line-of-sight (LOS) angle, the guidance system is established by defining the LOS angular rate as the state variable. …”

Revisiting the driving force underlying Chinese PM2.5 emissions: From the two perspectives of GVC and IDA by Jie Yan, Mao Zhou, Yunong Li, Bo Wang

“…ABSTRACT: The depth and breadth of participation in the global value chain (GVC) significantly impacts a country's fine particulate contamination (PM2.5) emissions. First, based on the GVC accounting framework, the sources of PM2.5 emissions in China between 1990 and 2015 are identified and investigated considering production-side, consumption-side, and export-implied pollution. …”
