Time-equispaced inertial measurements are practically used as inputs for motion determination. Polynomial interpolation is a common technique of recovering the gyroscope signal but subject to fundamentally numerical stability problem due Runge effect on equispaced samples. This paper reviews theoretical results phenomenon in related areas and proposes straightforward borrowing-and-cutting (BAC)...

There has been a lot of interest in recent years in using inertial sensors (accelerometers and gyroscopes) to monitor movement disorder motion and monitor the efficacy of treatment options. Two of the most prominent movement disorders, which are under evaluation in this research paper, are essential tremor (ET) and Parkinson's disease (PD). These movement disorders are first evaluated to show t...

The purpose of this investigation was to determine the effect of different lifting cadences on the ground reaction force (GRF) during the squat exercise. Squats performed with greater acceleration will produce greater inertial forces; however, it is not well understood how different squat cadences affect GRF. The hypotheses were that faster squat cadences would result in greater peak GRF and th...

derived dynamically by Hasenöhrl differs from between the energy and linear momentum ( and Newtonian time by the Doppler effect expanded to second order to relation is the correct one for a radiation velocity-induced Doppler effect expanded to the second order results in an increase in the radiation. The velocity-dependent increase in the internal of entropy consistent with Planck’s blackbody r...

In this paper we show that the Scharnhorst effect (Vacuum with boundaries or a Casimir type vacuum) cannot be used to generate signals showing measurable faster-than-c speeds. Furthermore, we aim to show that the Scharnhorst effect would violate special relativity, by allowing for a variable speed of light in vacuum, unless one can specify a small invariant length scale. This invariant length s...

Under the classical non-relativistic consideration of the space-time we propose the model of the laws of gravity and Electrodynamics, invariant under the galilean transformations and moreover, under every change of non-inertial cartesian coordinate system. Being in the frames of non-relativistic model of the space-time, we adopt some general ideas of the General Theory of Relativity, like the a...

Abstract: The paper presents a redundant architecture of a bi-dimensional strap-down inertial navigator in vertical plane. The redundance of the developed system is provided by its inertial measurement unit, containing inertial sensors arrays in a linear redundant configuration. The inertial sensors data in each of the three arrays (two for accelerometers and another one for gyros) are fused by...
