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.

PARTICLE SWARM OPTIMIZATION FOR INVERSE KINEMATICS SOLUTION AND TRAJECTORY PLANNING OF 7-DOF AND 8-DOF ROBOT MANIPULATORS BASED ON UNIT QUATERNION REPRESENTATION

Journal of Applied Engineering Science, 2021
Finding the inverse kinematic solution of a serial manipulator has always attracted the attention of optimization enthusiasts, as the solution space is highly nonlinear and, depending on the number of degrees of freedom, has multiple solutions.

Structure, Kinematics, and Observability of the Large Magellanic Cloud’s Dynamical Friction Wake in Cold versus Fuzzy Dark Matter [PDF]

Astrophysical Journal, 2023
The Large Magellanic Cloud (LMC) will induce a dynamical friction (DF) wake on infall to the Milky Way (MW). The MW’s stellar halo will respond to the gravity of the LMC and the dark matter (DM) wake, forming a stellar counterpart to the DM wake.

Artificial intelligence for improved fitting of trajectories of elementary particles in dense materials immersed in a magnetic field

Communications Physics, 2023
Particle track fitting is crucial for understanding particle kinematics. In this article, we use artificial intelligence algorithms to show how to enhance the resolution of the elementary particle track fitting in dense detectors, such as plastic ...

Radiative corrections to neutron and nuclear β-decays: a serious kinematics problem in the literature

Journal of High Energy Physics, 2023
We report a serious kinematics problem in the bremsstrahlung photon part of the order-α outer (model independent) radiative correction calculations for those neutron (and nuclear beta) decay observables (like electron-neutrino correlation parameter ...

Inverse Kinematics for Serial Robot Manipulators by Particle Swarm Optimization and POSIX Threads Implementation

Applied Sciences, 2023
Inverse kinematics is a fundamental problem in manipulator robotics: a set of joint angles must be calculated so that the robot arm can be manipulated to the corresponding desired end effector position and orientation (also known as “pose”).

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 ...

Capability of discrete element method to investigate the macro-micro mechanical behaviours of granular soils considering different stress conditions and morphological gene mutation

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 ...

A Note on the Acceleration and Jerk in Motion Along a Space Curve

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
The resolution of the acceleration vector of a particle moving along a space curve is well known thanks to Siacci [1]. This resolution comprises two special oblique components which lie in the osculating plane of the curve.

Unperturbed inverse kinematics nucleon knockout measurements with a carbon beam [PDF]

Nature Physics, 2021
Particle knockout scattering experiments1,2 are fundamental for mapping the structure of atomic nuclei2–6, but their interpretation is often complicated by initial- and final-state interactions of the incoming and scattered particles1,2,7–9.
