Deduction of Lorentz Transformations from Classical Thermodynamics

Entropy, 2015
The Lorentz transformations are obtained by assuming that the laws of classical thermodynamics are invariant under changes of inertial reference frames.

Frames of reference in spaces with affine connections and metrics

, 1999
A generalized definition of a frame of reference in spaces with affine connections and metrics is proposed based on the set of the following differential-geometric objects: (a) a non-null (non-isotropic) vector field, (b) the orthogonal to the vector

About ideal relative motions of rigid heavy body [PDF]

INCAS Bulletin, 2017
Consider an origin which is fixed at the Earth’s surface, and a rectangular celestial coordinates axes with this origin. The gravity acceleration is the approximate sum of the centrifugal acceleration of the origin relatively to the Earth’s center and ...

Locally Inertial Reference Frames in Lorentzian and Riemann-Cartan Spacetimes

, 2011
In this paper we scrutinize the concept of locally inertial reference frames (LIRF) in Lorentzian and Riemann-Cartan spacetime structures. We present rigorous mathematical definitions for those objects, something that needs preliminary a clear ...

Teleparallel Theories of Gravity: Illuminating a Fully Invariant Approach [PDF]

, 2019
Teleparallel gravity and its popular generalization $f(T)$ gravity can be formulated as fully invariant (under both coordinate transformations and local Lorentz transformations) theories of gravity.

Implications of an absolute simultaneity theory for cosmology and universe acceleration. [PDF]

PLoS ONE, 2014
An alternate Lorentz transformation, Absolute Lorentz Transformation (ALT), has similar kinematics to special relativity yet maintains absolute simultaneity in the context of a preferred reference frame.

Experimental Test of Relativistic Quantum State Collapse with Moving Reference Frames [PDF]

, 2000
An experimental test of relativistic wave-packet collapse is presented. The tested model assumes that the collapse takes place in the reference frame determined by the massive measuring detectors. Entangled photons are measured at 10 km distance within a

One-Step Initial Alignment Algorithm for SINS in the ECI Frame Based on the Inertial Attitude Measurement of the CNS

Sensors, 2022
To solve the problem of high-precision and fast initial alignment for the Strapdown Inertial Navigation System (SINS) under both dynamic and static conditions, the high-precision attitude measured by the celestial navigation system (CNS) is used as the ...

Electrodynamics in accelerated frames revisited

, 2010
Maxwell's equations are formulated in arbitrary moving frames by means of tetrad fields, which are interpreted as reference frames adapted to observers in space-time.
