A new kinematical definition of orbital eccentricity [PDF]

open access: yesSerbian Astronomical Journal, 2009
A new concept of orbital eccentricity is given. The dimensionless quantities proposed in the present paper to serve as orbital eccentricities have a kinematical nature. The purpose is to use them in describing the motion for the case of three-dimensional

On Orbits for a Particular Case of Axial Symmetry [PDF]

open access: yesSerbian Astronomical Journal, 2009
A particular case of steady state and axial symmetry - the potentialformula proposed by Miyamoto and Nagai - is studied. A number of orbits of abound test particle is determined numerically, with both, the potentialparameters and initial conditions ...

Exploring the Fundamental Mechanism in Driving Highest-Velocity Ionized Outflows in Radio AGNs

open access: yesUniverse, 2022
We investigate the ionized gas kinematics relationship with X-ray, radio and accreting properties using a sample of 348 nearby ...

“Kinematics and Dynamics” [PDF]

open access: yesNature, 1888
MAY I ask a short space in your columns to refer to a few points in Prof. Greenhill's review of my book on “Kinematics and Dynamics,” published in your issue of February 16 (p. 361). I shall be as brief as possible.

Computational Dynamics of Multi-Rigid-Body System in Screw Coordinate

open access: yesApplied Sciences, 2023
This paper investigates the kinematics and dynamics of multi-rigid-body systems in screw form. The Newton–Euler dynamics equations are established in screw coordinates. All forces and torques of the multi-rigid-body system can be solved straightforwardly

Sleep-push movement performance in elite field hockey champions with and without training specialization

open access: yesFrontiers in Psychology, 2023
ObjectiveTo investigate kinematic and muscle activity differences during the sleep-push movement in elite field hockey players. We hypothesized that players with specialized sleep-push movement training (specialists) would possess a lower center of mass (

Gasflows in Barred Galaxies with Big Orbital Loops—A Comparative Study of Two Hydrocodes

open access: yesUniverse, 2022
We study the flow of gas in a barred-galaxy model, in which a considerable part of the underlying stable periodic orbits have loops where, close to the ends of the bar, several orbital families coexist and chaos dominates.

Kinematics and Dynamics [PDF]

open access: yesSymposium - International Astronomical Union, 1968
I would probably not be mistaken in saying that for the first time in the practice of solid scientific meetings the problem of the dynamics of planetary nebulae has become a subject of broad and sufficiently many-sided discussion. At the same time, I am inclined to estimate the successes achieved at the present symposium as more than modest.
