The Absolute Frame of Reference [PDF]

open access: yesSSRN Electronic Journal, 2020
The manuscript found the formula to calculate the real velocity of the earth and the maximum velocity in the universe, the values of the quantities after calculation as follows:V_earth = 1.852819296∗10^8 m/s.C_max = 4.8507438399∗10^8 m/s.In order to calculate the above results, the manuscript has built a reference frame transformation suitable for ...

Dynamics of a quantum reference frame [PDF]

open access: yesNew Journal of Physics, 2007
We analyze a quantum mechanical gyroscope which is modeled as a large spin and used as a reference against which to measure the angular momenta of spin-1/2 particles. These measurements induce a back-action on the reference which is the central focus of our study.

Answering Mermin's challenge with conservation per no preferred reference frame. [PDF]

open access: yesSci Rep, 2020
In 1981, Mermin published a now famous paper titled, "Bringing home the atomic world: Quantum mysteries for anybody" that Feynman called, "One of the most beautiful papers in physics that I know." Therein, he presented the "Mermin device" that ...

Reduced Reference Frame Transformation Assessment in Unbalanced Three-Phase Four-Wire Systems

open access: yesIEEE Access, 2023
Three-phase four-wire systems require a reference frame similar to that used in 3-phase 3-wire system configurations that allow them to be easily analysed, modelled and controlled.

Operational Quantum Reference Frame Transformations [PDF]

open access: yesQuantum
Quantum reference frames are needed in quantum theory for much the same reasons that reference frames are in classical theories: to manifest invariance in line with fundamental relativity principles and to provide a basis for the definition of observable

Deformed symmetries from quantum relational observables [PDF]

open access: yes, 2007
Deformed Special Relativity (DSR) is a candidate phenomenological theory to describe the Quantum Gravitational (QG) semi-classical regime. A possible interpretation of DSR can be derived from the notion of deformed reference frame.

Effects of initial eye position on saccades evoked by microstimulation in the primate superior colliculus: implications for models of the SC read-out process

open access: yesFrontiers in Integrative Neuroscience, 2011
The motor layers of the superior colliculus (SC) are thought to specify saccade amplitude and direction, independent of initial eye position. However, recent evidence suggests that eye position can modulate the level of activity of SC motor neurons.

A two-point boundary value problem on a Lorentz manifold arising in A. Poltorak's concept of reference frame [PDF]

open access: yes, 2006
In A. Poltorak's concept, the reference frame in General Relativity is a certain manifold equipped with a connection. The question under consideration here is whether it is possible to join two events in the space-time by a time-like geodesic if they are
