Simulation and optimisation design of the solenoid valve
The Journal of Engineering, 2019 This study first analyses the problems that the solenoid valve generates during operation. Then the electromagnetic valve was modelled and ANSYS finite element analysis simulation software was used to simulate the electromagnetic field and transient ...

Measuring the magnetic axis alignment during solenoids working
Scientific Reports, 2018 A method for monitoring the misalignment of the magnetic axis in solenoids is proposed. This method requires only a few measurements of the magnetic field at fixed positions inside the magnet aperture, and thus overcomes the main drawback of sturdy ...

Space-Based Gravity Detector for a Space Laboratory [PDF]
, 2002 A space-based superconducting gravitational low-frequency wave detector is considered. Sensitivity of the detector is sufficient to use the detector as a partner of other contemporary low-frequency detectors like LIGO and LISA.

The group of homeomorphisms of a solenoid [PDF]
Transactions of the American Mathematical Society, 1972 Let X be a topological space. An n-mean on X is a continuous function ,u: XX which is symmetric and idempotent. In the first part of this paper it is shown that if X is a compact connected abelian topological group, then X admits an n-mean if and only if H1(X, Z) is n-divisible where Hm(X, Z) is m-dimensional Cech cohomology with integers Z as ...

A New Method for Maintaining Constant Dither Amplitude in Low Frequency PWM
Advances in Electrical and Computer Engineering, 2017 Various controls for fluid flow and pressure are now required in related industries, and the pulse width modulation (PWM) and dithering techniques have become essential for the proportional control of solenoids.

Multistage Zeeman deceleration of atomic and molecular oxygen [PDF]
, 2018 Multistage Zeeman deceleration is a technique used to reduce the velocity of neutral molecules with a magnetic dipole moment. Here we present a Zeeman decelerator that consists of 100 solenoids and 100 magnetic hexapoles, that is based on a short ...

Explicit Construction of Equivalence Bimodules between Noncommutative Solenoids [PDF]
, 2014 Let $p\in \mathbb{N}$ be prime, and let $\theta$ be irrational. The authors have previously shown that the noncommutative $p$-solenoid corresponding to the multiplier of the group $\left(\mathbb{Z}\left[\frac{1}{p}\right]\right)^2$ parametrized by ...

Self-Similar Inverse Semigroups from Wieler Solenoids
Mathematics, 2020 Wieler showed that every irreducible Smale space with totally disconnected local stable sets is an inverse limit system, called a Wieler solenoid. We study self-similar inverse semigroups defined by s-resolving factor maps of Wieler solenoids.

Hodge Theory for Riemannian Solenoids [PDF]
, 2011 A measured solenoid is a compact laminated space endowed with a transversal measure. The De Rham $L^2$-cohomology of the solenoid is defined by using differential forms which are smooth in the leafwise directions and $L^2$ in the transversal direction.

Noncommutative solenoids and their projective modules [PDF]
, 2013 Let p be prime. A noncommutative p-solenoid is the C*-algebra of Z[1/p] x Z[1/p] twisted by a multiplier of that group, where Z[1/p] is the additive subgroup of the field Q of rational numbers whose denominators are powers of p.
