On rotating vectors, Jacobi elliptic functions and free vibration of the Duffing oscillator
(2020-11-01)
The free vibration displacement of an undamped hardening Duffing oscillator is described in exact form by a Jacobi elliptic function. Unlike an undamped linear oscillator, whose displacement is described by a trigonometric ...
Dynamics analysis and control of a pendulum driven by a DC motor via a slider-crank mechanism
(2022-03-01)
In the present work, we deal with a dynamical analysis and passive control of chaos with magnetic rheological (MR) rotational damper in a pendulum driven by a DC motor via slider mechanism. A mathematical model for ...
Correction of a severely rotated mandibular canine in an adult patient using invisalign: a case report
(2018)
Introduction: The Invisalign system has been used in the orthodontic treatment of numerous types of malocclusions. However some clinicians have reported difficulty incorrectingrotations particularly in canines ...
Late cenozoic tectonics and paleomagnetism of North Cauca Basin intrusions, Colombian Andes: Dual rotation modes
(ELSEVIER SCIENCE BV, 1996-09-15)
Further paleomagnetic results are reported from 18 sites in Late Tertiary hypabyssal igneous rocks adjacent to the Romeral fault system which forms the eastern boundary of the North Cauca Basin. The paleomagnetic directions ...
Time-dependent mass-transfer behaviour under laminar and turbulent flow conditions in rotating electrodes: A CFD study with analytical and experimental validation
(Pergamon-Elsevier Science Ltd, 2019-07)
Results of numerical calculations and their comparison with analytical expressions or experimental data under laminar and turbulent flow conditions are reported. It is predicted the transient and steady-state behaviour of ...
A Numerical Perspective On The Relation Between Particle Rotational Inertia And The Equilibrium Magnetization Of A Ferrofluid
(Elsevier Science BVAmsterdam, 2017)
Soil carbon fluxes and balances of crop rotations under long-term no-till
(2020-09-16)
Background: A field study with the same crop rotations was conducted to test the hypothesis that the soil Carbon fluxes and balances could vary according to the crop species and also mitigate carbon dioxide (CO2) emission. ...
Wide-Field Survey of Globular Clusters in M31. II. Kinematics of the Globular Cluster System
(2008)
We present a kinematic analysis of the globular cluster(GC) system in M31. Using the photometric and spectroscopic database of 504 GCs, we have investigated the kinematics of the M31 GC system. We find that the all GC ...
Effects of rotation in the laser-pulse photoassociation in a thermal gas of atoms
(Spie-int Soc Optical Engineering, 2013-01-01)
Photoassociation is a possible route for the formation of chemical bonds. In this process, the binding of colliding atoms can be induced by means of a laser field. Photoassociation has been studied in the ultracold regime ...
