A Modified Strain-Rate-Dependent Spring-Mass Model for Response Prediction of Composite Laminates Subjected to Low-Velocity Impact by Qiao Zhu, Zhefeng Yu

“…The constitutive relations of FRP material were modified with the impact-induced strain rate using Yen-Caiazzo’s function in space and time dimensions simultaneously. The stiffness coefficients of the spring-mass model were updated step-by-step during solving the Bubnov-Galerkin equation by the variational method, allowing the SRD contact history to be obtained via recursive integration. …”

Urban Land Grabbing: Analyzing Zones for Community Uses in Hong Kong by Mark Hansley Chua, Lawrence Wai Chung Lai

“…This study, as a contribution to the research on urban land grabbing (grabs) as a global phenomenon, seeks to evaluate the populist belief that developers swallow up urban land originally zoned for community purposes under Government, Institution and Community (GIC) zoning, thus depriving communities of space for their own benefit. The authors applied a systematic analysis of non-aggregate planning and development statistics to better interpret the features of the land market as regulated by zoning. …”
