Timber beam seismic design � A numerical simulation [PDF]

Fracture and Structural Integrity, 2019
In order to design a seismic timber beam, the effect of near-fault ground motion on timber beam has numerically been investigated, with reference to small displacement theory.

Inertial spin Hall effect in noncommutative space

, 2013
In the present paper the study of inertial spin current(that appears in an accelerated frame of reference) is extended to Non-Commutative (NC) space.

The Various Speeds of Lights in Inertial Frames of Reference [PDF]

Optics, 2017
The speed of light in empty space was first measured by Roemer in 1676 who also found it faster on approach to its source and slower on recession. James Bradley in 1728 reported the speed of light incident vertically to be higher on approach and slower on recession.

Rotational Reference Frame Control of DFIG-Based Wind Turbines for Inertial Frequency Response

IEEE Access
The rapid increase of wind power penetration has threatened the frequency stability of regional power grids, and the loss of system inertia is viewed as the key issue to be solved.

Velocity/Position Integration Formula (II): Application to Inertial Navigation Computation

, 2012
Inertial navigation applications are usually referenced to a rotating frame. Consideration of the navigation reference frame rotation in the inertial navigation algorithm design is an important but so far less seriously treated issue, especially for ...

Coordinates of Human Visual and Inertial Heading Perception. [PDF]

PLoS ONE, 2015
Heading estimation involves both inertial and visual cues. Inertial motion is sensed by the labyrinth, somatic sensation by the body, and optic flow by the retina.

Resonance interaction energy between two accelerated identical atoms in a coaccelerated frame and the Unruh effect

, 2016
We investigate the resonance interaction energy between two uniformly accelerated identical atoms, interacting with the scalar field or the electromagnetic field in the vacuum state, in the reference frame coaccelerating with the atoms.

Lacunae in the philosophical foundations of special relativity

Open Astronomy
Based on the two postulates of the invariance of both the laws of physics and light speed in inertial frames, Einstein revolutionised the prevalent conceptions of space and time in the Special Theory of Relativity, which is not however without ...

The Explanation of the Michelson-Morley Experiment Results by Means Universal Frame of Reference

, 2017
It is commonly thought that the Michelson-Morley experiment from 1887 and Kennedy-Thorndike experiment from 1932 demonstrated that the universal frame of reference (ether) does not exist and that the velocity of light in vacuum is absolutely constant ...
