Mapping the Kinematically Decoupled Core in NGC 1407 with MUSE

, 2018
Studies of the kinematics of NGC 1407 have revealed complex kinematical structure, consisting of the outer galaxy, an embedded disc within a radius of $\sim60$ arcsec, and a kinematically decoupled core (KDC) with a radius of less than 30arcsec. However,

Comparison of NNLO DIS scheme splitting functions with results from exact gluon kinematics at small x. [PDF]

, 2005
We consider the effect of exact gluon kinematics in the virtual photon-gluon impact factor at small x. By comparing with fixed order DIS scheme splitting and coefficient functions, we show that the exact kinematics results match the fixed order results ...

Kinematic gait analysis in hemiplegic patients

Journal of Rehabilitation Medicine, 1993
Temporal-distance variables of gait were investigated in 8 female and 23 male hemiplegic patients in order to assess the distribution of these variables according to functional ambulation category and to evaluate their validity. Video-recording technique was used for obtaining the temporal-distance values.

Kinematics and Performance Analysis of the 2T1R/1T2R Reconfigurable Decoupled Parallel Mechanism

Applied Sciences
Based on the reconfigurable revolute (rR) pair, a reconfigurable decoupled parallel mechanism is proposed, which is composed of three serial chains. Traditional serial chain 1 and 2 are of types PRRR and URC, respectively, where P denotes a prismatic ...

The Two-fold Role of Observables in Classical and Quantum Kinematics [PDF]

, 2017
Observables have a dual nature in both classical and quantum kinematics: they are at the same time \emph{quantities}, allowing to separate states by means of their numerical values, and \emph{generators of transformations}, establishing relations between

Kinematics Analysis of a Six-axis Welding Manipulator

Journal of Harbin University of Science and Technology, 2019
Given that of the actual environment of the welding site is not the same, and the problem that the traditional welding robot can not fully adatp to a variety of different welding environment, we put forward a design of a six-axis welding robot.
