Particle Kinematics in Hořava-Lifshitz Gravity
We study the deformed kinematics of point particles in the Hořava theory of gravity. This is achieved by considering particles as the optical limit of fields with a generalized Klein-Gordon action. We derive the deformed geodesic equation and study in detail the cases of flat and spherically symmetric (Schwarzschild-like) spacetimes. As the theory is not invariant under local Lorenz transformat...
متن کاملAssessing particle kinematics via template matching algorithms.
Template matching algorithms represent a viable tool to locate particles in optical images. A crucial factor of the performance of these methods is the choice of the similarity measure. Recently, it was shown in [Gao and Helgeson, Opt. Express 22 (2014)] that the correlation coefficient (CC) leads to good results. Here, we introduce the mutual information (MI) as a nonlinear similarity measure ...
متن کاملDefect particle kinematics in one-dimensional cellular automata
Let A be the Cantor space of bi-infinite sequences in a finite alphabet A, and let σ be the shift map on A. A cellular automaton is a continuous, σ-commuting self-map Φ of A, and a Φ-invariant subshift is a closed, (Φ, σ)-invariant subset S ⊂ A. Suppose a ∈ A is S-admissible everywhere except for some small region we call a defect. It has been empirically observed that such defects persist unde...
متن کاملKinematics Design of a Planar Parallel Controllable Mechanism Based on Particle Swarm Optimization Algorithm
Planar parallel controllable mechanism, which is a combination of two types of motor and mechanism, has better flexible transmission behavior. In this paper, the kinematics analysis for a planar parallel controllable fivebar mechanism is introduced. In order to improve kinematic performance of the controllable mechanism, an optimization design for the mechanism is performed with reference to ki...
متن کاملInverse Kinematics of Serial Manipulators in Cluttered Environments Using a New Paradigm of Particle Swarm Optimization
In this paper, a new Behavioral-based Particle Swarm Optimization algorithm is proposed in order to solve the inverse kinematics problem for a manipulator operating in an environment cluttered with obstacles. The introduced variant of the Particle Swarm Optimization relies on the idea of dividing the population of the particles in subgroups, each of which with a specific task, achieving in this...
