Bi-adjoint scalars are helpful in studying properties of color/kinematics duality and the double copy, which relates scattering amplitudes gauge gravity theories. Here we study bi-adjoint from a worldline perspective. We show how global $G \times \tilde G$ symmetry group may be realized by degrees freedom. The action gives rise to vertex operators, compared similar ones describing coupling fiel...

Abstract Wire-Cell is a 3D event reconstruction package for liquid argon time projection chambers. Through geometry, time, and drifted charge from multiple readout wire planes, space points with associated are reconstructed prior to the pattern recognition stage. Pattern techniques, including track trajectory d Q /d x (ionization per unit length) fitting, neutrino vertex shower separation, part...

This paper presents the kinematic analysis and the development of a 4-degree-of-freedom serial-parallel mechanism for large commercial vehicle driving simulators. The degrees of freedom are selected according to the target maneuvers and the structure of human motion perception organs. Several kinematic properties of parallel part of the mechanism under study are investigated, including the inve...

The limb-driving force mutation of the modular combination parallel manipulator (MCPM) affects alignment process optical axis. In this paper, a novel optimization method based on penalty term is proposed to solve problem driving mutation. kinematics and dynamics models are established using modularization idea, reducing complexity modeling process, verified co-simulation. Moreover, particle swa...

Kinematics studies the motion of bodies without consideration of the forces or moments that cause the motion. Robot kinematics refers the analytical study of the motion of a robot manipulator. Formulating the suitable kinematics models for a robot mechanism is very crucial for analyzing the behaviour of industrial manipulators. There are mainly two different spaces used in kinematics modelling ...

Recent radio and x-ray data from radio sources in galaxy clusters are used to place constraints on the particle content and kinematics of jets that supply these radio sources. These data show that the pdV work required to inflate the radio lobes in the ICM exceeds all other estimates of the amount of energy needed to supply the observed radio emission. If the required jet energy density has an ...

Robust dead reckoning is a complicated problem for wheeled mobile robots (WMRs), where the robots are faulty, such as the sticking of sensors or the slippage of wheels, for the discrete fault models and the continuous states have to be estimated simultaneously to reach a reliable fault diagnosis and accurate dead reckoning. Particle filters are one of the most promising approaches to handle hyb...

This study reports the mutual transformations between the third-order Eulerian and Lagrangian solutions for the irrotational progressive gravity waves propagating on the uniform depth. Based on the fundamental principle of kinematics, the instantaneous Eulerian and Lagrangian velocities are identically equal, and using a successive Taylor series expansion to the path and the period of particle ...
