Multi-body kinematics and dynamics in terms of quaternions: Langrange formulation in covariant form: Rodriguez approach [PDF]
FME Transactions, 2010 This paper suggests a quaternion approach for the modeling kinematics and dynamics of rigid multi-body systems. Instead of the regular 'Newton-Euler' and Lagrange method used in the traditional way, Lagrange's equations of second kind in the covariant ...

On the Validity of the Euler–Lagrange Equation
Journal of Differential Equations, 2001 The paper concerns the following minimization problem \[ \text{Min } \int_\Omega [f(\|\nabla u(x)\|)+ g(x,u(x))] dx,\quad u- u^0\in W^0\in W^{1,1}_0(\Omega), \] where \(\Omega\) is an open bounded domain with Lipschitz boundary, \(W^0\) is a linear subset of \(W^{1,1}_0(\Omega)\) which contains all \(w\in W^{1,1}\) with \(\int_\Omega f(\|\nabla w(x)\|)

Business Strategy and the Environment, EarlyView.ABSTRACT Despite the critical role that state‐owned enterprises (SOEs) can play in the green transition, relatively little is known about governments' environmental behavior as foreign shareholders. This study examines the effect of state ownership on domestic and foreign environmental performance.

On the Motion of Harmonically Excited Spring Pendulum in Elliptic Path Near Resonances
Advances in Mathematical Physics, 2016 The response of a nonlinear multidegrees of freedom (M-DOF) for a nature dynamical system represented by a spring pendulum which moves in an elliptic path is investigated. Lagrange’s equations are used in order to derive the governing equations of motion.
