FEATURES OF THE ANGULAR SPEED DYNAMIC MEASUREMENTS WITH THE USE OF AN ENCODER
Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2022 Based on the most significant features of the angular velocity dynamic measurements selected by the authors, the main phases of measuring information transformation were established, which allowed to obtain new mathematical models in the form of ...

Diffusion of active particles with angular velocity reversal [PDF]
Physical Review E, 2021 Biological and synthetic microswimmers display a wide range of swimming trajectories depending on driving forces and torques. In this paper we consider a simple overdamped model of self-propelled particles with a constant self-propulsion speed, but an angular velocity that varies in time.

Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components
Advanced Engineering Materials, EarlyView.This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...

On the angular velocity slip in nano-flows [PDF]
Microfluidics and Nanofluidics, 2015 The need of reformulation for basic concepts of fluid mechanics in order to account some enhancement phenomena in micro- and nano-flows is presented in the paper. The work is a general formulation of angular velocity slip condition which is developed from primary principles.

Advanced Engineering Materials, EarlyView.Al–Si alloys are particularly in demand for automotive and electronic applications, thanks to their excellent wear and thermal properties. Nevertheless, when processed by conventional methods with low cooling rates, the coarse primary Si phases are responsible for increasing brittleness and inducing crack propagation.

Angular Velocity Estimation for Nanosatellites Using Vector Measurements
Havacılık ve Uzay Teknolojileri Dergisi, 2021 In the absence of gyro sensors, the straightforward approach to estimate the angular velocity is using a dynamics-based attitude filter which can provide angular rate information together with the attitude of the satellite.

Destroying superfluidity by rotating a Fermi gas at unitarity
, 2008 We study the effect of the rotation on a harmonically trapped Fermi gas at zero temperature under the assumption that vortices are not formed. We show that at unitarity the rotation produces a phase separation between a non rotating superfluid (S) core ...
