IMAGES I. Strong evolution of galaxy kinematics since z=1 [PDF]

open access: yes, 2007
(abbreviated) We present the first results of the ESO large program, ``IMAGES'' which aims at obtaining robust measurements of the kinematics of distant galaxies using the multi-IFU mode of GIRAFFE on the VLT.

Kinematic Space and Wormholes [PDF]

open access: yesJournal of High Energy Physics, 2017(1), 1-27, 2016
The kinematic space could play a key role in constructing the bulk geometry from dual CFT. In this paper, we study the kinematic space from geometric points of view, without resorting to differential entropy. We find that the kinematic space could be intrinsically defined in the embedding space.

A speedup method for solving the inverse kinematics problem of robotic manipulators

open access: yesInternational Journal of Advanced Robotic Systems, 2022
The inverse kinematics problem involves the study that the inverse kinematics solver needs to calculate the values of the joint variables given the desired pose of the end-effector of a robot.

Kinematic Mappings for Cayley-Klein Geometries via Clifford Algebras [PDF]

open access: yesContributions to Algebra and Geometry 54 (2013), 737-761, 2013
This paper unifies the concept of kinematic mappings by using geometric algebras. We present a method for constructing kinematic mappings for certain Cayley-Klein geometries. These geometries are described in an algebraic setting by the homogeneous Clifford algebra model. Displacements correspond to Spin group elements.

Molecular Gas Kinematics in Barred Spiral Galaxies [PDF]

open access: yes, 1999
To quantify the effect that bar driven mass inflow can have on the evolution of a galaxy requires an understanding of the dynamics of the inflowing gas.

Robot Kinematics: Forward and Inverse Kinematics [PDF]

open access: yes, 2006
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.

The Kinematics of Pulsars [PDF]

open access: yesSymposium - International Astronomical Union, 1985
Pulsars have a galactic radial distribution similar to that of many galactic populations such as HII regions, massive stars and supernova remnants. However they are generally much further from the plane of the Galaxy than these objects. Proper motion measurements sho that this is because they are typically moving with high velocities.
