Effect of the Converging Pipe on the Performance of a Lucid Spherical Rotor [PDF]
Arabian Journal for Science and Engineering, 2018 Lucid spherical rotor is a cross-flow rotor developed to be installed within a pipeline. The purpose of installing this type of rotor is to collect excess energy available in gravity-fed water pipelines. In order to enhance the efficiency of the rotor which is installed in a channel, this paper aims to study the performance of Lucid spherical rotor ...

A New Rotor Position Measurement Method for Permanent Magnet Spherical Motors
Applied Sciences, 2018 This paper proposes a new high-precision rotor position measurement (RPM) method for permanent magnet spherical motors (PMSMs). In the proposed method, a LED light spot generation module (LSGM) was installed at the top of the rotor shaft.

Strong Spherical Asymptotics for Rotor-Router Aggregation and the Divisible Sandpile [PDF]
Potential Analysis, 2007 The rotor-router model is a deterministic analogue of random walk. It can be used to define a deterministic growth model analogous to internal DLA. We prove that the asymptotic shape of this model is a Euclidean ball, in a sense which is stronger than ...

Supersymmetry and eigensurface topology of the planar quantum pendulum [PDF]
Frontiers in Physics, 2014 We make use of supersymmetric quantum mechanics (SUSY QM) to find three sets of conditions under which the problem of a planar quantum pendulum becomes analytically solvable.
