The Cart-Inverted Pendulum System (CIPS) is a classical benchmark control problem. Its dynamics resembles with that of many real world systems of interest like missile launchers, pendubots, human walking and segways and many more. The control of this system is challenging as it is highly unstable, highly non-linear, non-minimum phase system and underactuated. Further, the physical constraints o...

Garnet films of composition (Lu,Bi)3(Fe,Ga,Al)5O12 and (Tm,Bi)3(Fe,Ga)5O12 are grown by liquid-phase epitaxy on [111]-oriented substrates of gadolinium gallium garnet. Ferrimagnetic films with positive or negative Faraday-rotation as well as paramagnetic films with negligible Faraday-rotation are produced by variations of the rare earth ion substitutions. The temperature dependence of Faraday-r...

Double Curved Concave Surface Sliders (DCCSS) are seismic isolators based on the pendulum principle widely used worldwide. Coherently with European code, DCCSS do not include any mechanical elements as end-stopper. In case of displacement higher than those associated design earthquakes, inner slider runs edge sliding surfaces beyond their geometric capacity keeping ability to support gravity lo...

In 1851, Stokes (in insert) calculated the friction force on a cylinder in oscillating motion, neglecting nonlinear term of Navier-Stokes equation, an approximation valid for vanishing values Reynolds number Re. Previous tests were performed with Re>0.1 and frequently Re>>1. We have measured oscillation macroscopic gravity pendulum. Our position detector submicrometer sensitivity enables us ...

Introduction Creating compact on-chip non-reciprocal components is of fundamental interest in integrated optics at telecom wavelength of 1.55 μm. Today a lot of integrated functions are available commercially such as lasers, couplers, filters, modulators, but there is a lack of non-reciprocal integrated functions like optical isolators and circulators. Commercial optical isolators are expensive...

The main purpose of this work is, first, a construction the indirect Hamilton’s variational principle for problem motion pendulum with vibration suspension friction, oscillating along straight line making small angle vertical line. Second, on its basis difference scheme. Third, to carry out investigation by methods numerical analysis. Methods. indicated is considering as particular case given b...
