The objective is to study the motion of an ellipsoidal capsule in a simple shear flow when its revolution axis is initially placed off the shear plane. We consider prolate capsules with an aspect ratio of 2 or 3 enclosed by a membrane, which is either strain-hardening or strain-softening. We seek the equilibrium motion of the capsule as we increase the capillary number Ca, which measures the ra...

Abstract This study describes a method for swinging up and stabilizing double inverted pendulum (DIP) in real-time utilizing PID-LQR combined control system. Firstly, dynamic model of the system is made equations motion are constructed. The then moved from its unstable position to stable one using controller. A comparison controller’s output suggestions improving stability presented suggested

Sucrose density-gradient analysis is one method of identifying specific estrogen and progesterone receptors in mammary tumor tissue. Use of the vertical rotor makes this practical for routine applications in the clinical laboratory by increasing the number of samples that can be run at one time and shortening the centrifuge time from 18 to less than 2 h. The separations and reproducibility comp...

The swinging up control for a remotely driven Acrobot (RDA) is studied and an energy based controller is designed via the Lyapunov stability theory. The analysis of convergence of the energy as well as the motion of the RDA under the controller is presented. The conditions on control parameters for achieving a successful swinging up control are given. Furthermore, simulation and experimental re...
