DOES VENTURE CAPITAL AFFECT CROWDFUNDING PERFORMANCE?
Published 2021-11-01“…Specifically, we split 274,220 crowdfunding projects into venture capital- and non-venture capital-funded projects and examined whether this type of financing enhances the performance of crowdfunding campaigns—measured by the number of crowdfunders and the amount of proceeds raised by the crowdfunding campaigns. The results of linear regression models reveal that the venture capital-funded entrepreneurial firms perform better in the crowdfunding market than their non-funded peers. …”

基于3R伪刚体模型的柔顺杆动力学建模及分析
Published 2013-01-01“…The 3R pseudo-rigid-body model of compliant mechanism is introduced.The kinetic energy equation and deformation energy equation of compliant bar is deduced by Matlab software symbolic operation.The dynamics model of the compliant bar under the action of end load by applying Lagrange equation.The centripetal force factor,the moment of inertia factor,and the Carioles force factor are obtained through characteristic radius factor and stiffness factor substituted into equations group,and mutual coupling effect of the angle variable are analyzed.The dynamic response curves and its configuration charts are obtained through the numerical solution of two order variable coefficient linear differential equations.It shows that the pseudo-rigid-body amplitude from 1-bar to 3-bar increases gradually and rod coupling reduces.The result shows that the dynamics equations of 3R pseudo-rigid body model are more practical and versatile for simulating the dynamics characteristics of compliant bar than 2R pseudo-rigid body model.…”
