Block diagonalisation of four-dimensional metrics [PDF]
It is shown that, in 4-dimensions, it is possible to introduce coordinates so that an analytic metric locally takes block diagonal form. i.e. one can find coordinates such that g = 0 for (, ) 2 S where S = {(1, 3), (1, 4), (2, 3), (2, 4)}.

Stewart platform pneumatic control system development and characteristic research
The paper presents the results of improving the Stewart platform control system by applying the second-order regulation law to pneumatic drive controllers and transformation of the actuating signal for the functioning of valves in the linear region of ...

Reconsidering the galactic coordinate system [PDF]
Initially defined by the IAU in 1958, the galactic coordinate system was thereafter in 1984 transformed from the B1950.0 FK4-based system to the J2000.0 FK5-based system. In 1994, the IAU recommended that the dynamical reference system FK5 be replaced by

Kinematics and singularity analysis of UR5 robot
In order to solve the problem that the UR5 robot coordinate system established by the user is inconsistent with the manufacturer's, and the data related to the force, angular velocity, angular acceleration are difficult to be directly used, based on the ...

Radial Stellar Pulsation and 3D Convection. I. Numerical Methods and Adiabatic Test Cases [PDF]
We are developing a 3D radiation hydrodynamics code to simulate the interaction of convection and pulsation in classical variable stars. One key goal is the ability to carry these simulations to full amplitude in order to compare them with observed light

Automatic anatomical foot and ankle coordinate toolbox
Accurate analysis of bone position and orientation in foot and ankle studies relies on anatomical coordinate systems (ACS). Reliable ACSs are necessary for many biomechanical and clinical studies, especially those including weightbearing computed ...
