The classical Coriolis force finds its quantum analogue in the difference $\Sigma(t)=H(t)-G(t)$ where ``true'', observable Hamiltonian $H(t)$ represents instantaneous energy. other, ``false'' $G(t)$ generates time-evolution of wave functions. Whenever $\Sigma(t)\neq 0$, mechanics acquires an interaction-picture form. Then, every is generated by operator $\Sigma(t)$ ({\it alias} ``Heisenberg'' H...

An adaptive neural network controller for autonomous underwater vehicles (AUVs) is presented in this paper. The AUV model is highly nonlinear because of many factors, such as hydrodynamic drag, damping, and lift forces, Coriolis and centripetal forces, gravity and buoyancy forces, as well as forces from thruster. In this regards, a nonlinear neural network is used to approximate the nonlinear u...

In this paper we present an automatic model identification tool of ABB's industrial robots. The tool has been developed entirely in Matlab and has made extensive use of the graphical-user-interface options and the objectoriented design philosophy made possible in Matlab versions 5.0 and newer. The tool is able to automatically identify rigid-body robot parameters such as inertias and Coriolis f...

A special attention is paid to the motion of flexible links in a robotic configuration. The elastic deformation is a dynamic value which depends on the total dynamics of the robot system movements. The Euler-Bernoulli equation should be expanded according to the requirements of the motion complexity of elastic robotic systems. The EulerBernoulli equation (based on the existing laws of dynamics)...

Submarine channel–levee systems are among the largest sedimentary structures on the ocean floor. These channels have a sinuous pattern and are the main conduits for turbidity currents to transport sediment to the deep ocean. Recent observations have shown that their sinuosity decreases strongly with latitude, with high-latitude channels being much straighter than similar channels near the Equat...

In this paper, classical thin shell theory is used to analyze vibration and critical speed of simply supported rotating orthotropic cylindrical shell. The effects of centrifugal and Coriolis forces due to the rotation are considered in the present for‌mulation.. In addition, axial load is applied on cylinder as a ratio of critical buckling load. Finally the effects of orthotropic ratio, materia...
