On Centered Co-circular Central Configurations of the n-Body Problem [PDF]
Journal of Dynamics and Differential Equations, 2018 We study the co-circular central configurations of the n-body problem for which the center of mass and the center of the common circle coincide. In particular, we prove that there are no central configurations of this type with all the masses equal except one.

Circular Restricted n-Body Problem
Journal of Guidance, Control, and Dynamics, 2022 This paper introduces the Circular Restricted n-Body Problem (CRNBP), an extension of the bicircular restricted four-body problem (BCR4BP) designed to describe the dynamics of an n-body system. In the CRNBP, each massive body in the system is constrained to follow a Keplerian motion, similar to the BCR4BP's artificial constraint.

Amplitude Enhancement of Flow-Induced Vibration for Energy Harnessing [PDF]
E3S Web of Conferences, 2020 In this paper, flow-induced vibrations of bluff bodies with four different cross-sectional geometries (circle, square, triangle and semi-circle) arranged both in single and tandem (gap ratio equals to 3 and 5) configurations are investigated in a wind ...

An Optimization of a Circular Antenna Array for On-Body Communication
2023 17th European Conference on Antennas and Propagation (EuCAP), 2023 A non-uniform circular array wrapped around the waist is proposed for on-body communication with uniform on-body coverage at 5 GHz. To investigate the feasibility of such an array, we determined the path loss between such an array and on-body nodes using simulations and measurements on a cylindrical phantom and a real person.

The stability of orbit of a planet in the field of binary stars
Physical Sciences and Technology, 2021 In the paper, we consider the motion of a planet in the field of the binary stars in the theory of generalrelativity (GR), when all bodies have their own rotation. We consider that the third body moves in the planof massive two bodies.

Design of a Low-Energy Earth-Moon Flight Trajectory Using a Planar Auxiliary Problem
Applied Sciences, 2023 The paper presents a sufficiently simple technique for designing a low-energy flight trajectory of a spacecraft (SC) from the Earth to the Moon with insertion into a low circular orbit of the latter.

Frontiers in Mechanical Engineering, 2020 Two-dimensional Cattaneo–Mindlin problem on a contact with slip and adhesion between two elastic bodies of the same material is considered in classical statement for circular cylinders as well as in more general statements: for non-circular cylinders ...

Dynamics of tidal synchronization and orbit circularization of celestial bodies [PDF]
Physical Review E, 2008 We take a dynamical-systems approach to study the qualitative dynamical aspects of the tidal locking of the rotation of secondary celestial bodies with their orbital motion around the primary. We introduce a minimal model including the essential features of gravitationally induced elastic deformation and tidal dissipation that demonstrates the details ...

B@belonline, 2022 Hegel is the philosopher of the circle. He famously posits the circular logic against virtually the entirety of modern philosophy, which equates the circle with tautology, petitio principii and ultimately falsehood.
