In this paper, a closed loop strategy in the vertical plane is derived in order to determine the thrust direction of a launch vehicle in terms of velocities to be gained The two velocities-to-be-gained are utilized, here, ...

Linearization of the nonlinear equations and iterative solution is the most well-known scheme in many engineering problems. For geodetic applications of the LEO satellites, e.g. the Earth’s gravity field recovery, one needs ...

Here, we present a novel two-step approach for optimum design of cellular truss-beams based on desired natural frequencies. The proposed approach at- tempts to decrease the design complexities, based on the so called ...

Multi-layer orthotropic finite cylindrical shells with a viscoelastic core in contact with fluids are gaining increasing importance in engineering. Vibrational control of these structures is essential at higher modes. In ...
