Generalized approach to Galileo’s swiftest descent problem on a circle [PDF]
Proceedings of the Estonian Academy of Sciences, 2023 Nearly 400 years ago Galileo Galilei posed a conjecture about the fastest descent on the lower half of a circle. Namely, he assumed that the descent along the circular arc itself is faster than along any broken line of chords.

Resolutions of the Jerk and Snap Vectors for a Quasi Curve in Euclidean 3-Space
Mathematics, 2021 This work aims at studying resolutions of the jerk and snap vectors of a point particle moving along a quasi curve in Euclidean 3-space E3. In particular, we obtain the resolution of the jerk and snap vectors along the quasi vectors and offer an ...

The Relativistic Harmonic Oscillator in a Uniform Gravitational Field
Mathematics, 2021 We present the relativistic generalization of the classical harmonic oscillator suspended within a uniform gravitational field measured by an observer in a laboratory in which the suspension point of the spring is fixed.

On the Resolution of the Acceleration Vector According to Bishop Frame
Universal Journal of Mathematics and Applications, 2021 In the second half of the 19th century, Siacci investigated the motion of a particle in space under the influence of any forces (Atti R Accad Sci. Torino \textbf{14}(1879)).

A New Moving Frame for Trajectories with Non-Vanishing Angular Momentum
Journal of Mathematical Sciences and Modelling, 2021 The theory of curves has a very long history. Moving frames defined on curves are important parts of this theory. They have never lost their importance.

A General Robot Inverse Kinematics Solution Method Based on Improved PSO Algorithm
IEEE Access, 2021 Robots whose geometric structure does not meet the Pieper criterion are called general robots. For the inverse kinematic operation of general robots, the closed solution method cannot be solved, and the numerical solution calculation amount is too large ...

Journal of Rock Mechanics and Geotechnical Engineering, 2023 Discrete element method (DEM) has been widely utilised to model the mechanical behaviours of granular materials. However, with simplified particle morphology or rheology-based rolling resistance models, DEM failed to describe some responses, such as the ...
