A Lagrange-D'Alembert formulation of the equations of motion of a helicopter carrying an externally suspended load [PDF]
The exact nonlinear equations of motion are derived for a helicopter with an extenal load suspended by fore and aft, rigid-link cables. Lagrange's form of D'Alembert's principle is used.

The Proper Motion of Draco II with HST Using Multiple Reference Frames and Methodologies
The Astrophysical JournalWe present proper motion (PM) measurements for Draco II, an ultrafaint dwarf satellite of the Milky Way. These PMs are measured using two epochs of Hubble Space Telescope (HST)/Advanced Camera for Surveys imaging separated by a 7 yr temporal baseline ...

Are OPERA neutrinos faster than light because of non-inertial reference frames? [PDF]
Astronomy & Astrophysics, 2012 Recent results from the OPERA experiment reported a neutrino beam traveling faster than light. The experiment measured the neutrino time of flight (TOF) over a baseline from the CERN to the Gran Sasso site. The neutrino beam arrives 60 ns earlier than a light ray would do.

Are rigid non-inertial frames of reference really rigid?
, 2013 In this paper the notion of the rigid frame of reference within special relativity is analysed. Three definitions of rigidity are formulated. By using several examples of non-inertial frames, it is shown that these definitions are not equivalent. It is also shown that so called M ller rigid non-inertial frames are locally rigid, but do not exhibit ...

The kinetic relativity theory – hiding in plain sight
Open PhysicsA question in physics is whether Special Relativity (SR) is the only theory that explains relativistic behavior. SR measures time dilation by a relative velocity between two frames.

An Alternative Theory on the Spacetime of Non-inertial Reference Frame
Applied Physics Research, 2017 In present paper, we have proposed an alternative theory on the spacetime of non-inertial reference frame (NRF) which bases on the requirement of general completeness (RGC) and the principle of equality of all reference frames (PERF). The RGC is that the physical equations used to describe the dynamics of matter and/or fields should include the ...

Charged Scalar Boson in Melvin Universe
UniverseThis work investigates the dynamics of a charged scalar boson in the Melvin universe by solving the Klein–Gordon equation with minimal coupling in both inertial and non-inertial frames.

Description and User Instructions for the Quaternion_to_Orbit_v3 Software [PDF]
For a given inertial frame of reference, the software combines the spacecraft orbits with the spacecraft attitude quaternions, and rotates the body-fixed reference frame of a particular spacecraft to the inertial reference frame.
