ABSTRACT Gravitational acceleration fields can be deduced from the collisionless Boltzmann equation, once distribution function is known. This constructed via method of normalizing flows data sets positions and velocities stars. Here, we consider application this technique to solar neighbourhood. We construct mock a linear superposition multiple ‘quasi-isothermal’ functions, representing stella...

There is a need for large-scale, real world, diverse, and context rich vehicle acceleration catalog that can be used to design, analyze, compare various intelligent transportation systems. This paper fulfills three primary objectives. First, it provides such through the Surface Accelerations Reference, which openly available as an interactive analytics tool well open downloadable dataset. The R...

The neotropical frog Leptodactylus albilabris exhibits the greatest sensitivity to substrate-borne vibrations (seismic stimuli) reported to date for any terrestrial animal. Nerve fibers from the source of this extraordinary sensitivity in the ear show clear stimulus-evoked modulations of their resting discharge rates in response to sinusoidal seismic stimuli with peak accelerations less than 0....

This article presents a performance measure, the actuation eficiency, which describes the imbalance between the end-effector accelerations achievable in different directions of non-redundant robotic manipulators. A key feature of the proposed measure is that in its development the unitam differences between linear and angular accelerations are treated in a physically meaningful manner. The memu...

OBJECTIVES To examine the validity and inter-unit reliability of 10 Hz GPS for measuring instantaneous velocity during maximal accelerations. DESIGN Experimental. METHODS Two 10 Hz GPS devices secured to a sliding platform mounted on a custom built monorail were towed whilst sprinting maximally over 10 m. Displacement of GPS devices was measured using a laser sampling at 2000 Hz, from which...

The goals of this study were to determine if the muscle contributions to vertical and fore-aft acceleration of the mass center differ between crouch gait and unimpaired gait and if these muscle contributions change with crouch severity. Examining muscle contributions to mass center acceleration provides insight into the roles of individual muscles during gait and can provide guidance for treatm...

Purpose: Predicting body Center of Mass (COM) acceleration is carried out with more accuracy based on the acceleration of three joints of lower limb compared to only accounting joints of hip and ankle. Given that trunk movement during quite standing is noticeable, calculating trunk acceleration in model might increase prediction accuracy of COM acceleration. Moreover, in previous research studi...
