Pauli Gaussian Fibonacci and Pauli Gaussian Lucas Quaternions

open access: yesMathematics, 2022
We have investigated new Pauli Fibonacci and Pauli Lucas quaternions by taking the components of these quaternions as Gaussian Fibonacci and Gaussian Lucas numbers, respectively. We have calculated some basic identities for these quaternions.

Geometrodynamics in a spherically symmetric, static crossflow of null dust [PDF]

open access: yes, 2006
The spherically symmetric, static spacetime generated by a crossflow of non-interacting radiation streams, treated in the geometrical optics limit (null dust) is equivalent to an anisotropic fluid forming a radiation atmosphere of a star.

A universal platform for magnetostriction measurements in thin films

open access: yes, 2015
We present a universal nanomechanical sensing platform for the investigation of magnetostriction in thin films. It is based on a doubly-clamped silicon nitride nanobeam resonator covered with a thin magnetostrictive film.

Vibration of a Laminated Beam with a Delamination Including Contact Effects

open access: yesShock and Vibration, Volume 11, Issue 3-4, Page 157-171, 2004., 2004
Certain results are presented in this paper on damped vibration of a laminated cantilever beam with a single closing delamination. In order to investigate this task the finite element method has been applied in the current study. For modelling the beam higher order shear deformation beam finite elements have been used.
