Generalized ideal classes in application to toroidal solenoids

Pacific Journal of Mathematics, 2022
. We study certain subgroups G A of Q n defined by non-singular n × n -matrices A with integer coefficients. In the first non-trivial case when n = 2, we give necessary and sufficient conditions for two such groups to be isomorphic. Namely, in the generic case

Theoretical and Experimental Study of Gyro-TWT Solenoids With Displacement and Tilt

IEEE Transactions on Electron Devices, 2022
Axis coincidence consideration is necessary in the design of gyrotron solenoids; besides, radial field component strongly affects the performance of gyrodevices owing to the transverse particle–wave interaction mechanism in it, especially for high ...

Machine Learning the Central Magnetic Flux Density of Superconducting Solenoids

Materials technology (New York, N.Y.), 2020
The central magnetic flux density is usually simulated via finite element methods that require a significant amount of inputs and computation resources. We develop the Gaussian process regression (GPR) model to shed light on the statistical relationship ...

Development of a high-speed solenoid valve: investigation of solenoids

IEEE Transactions on Industrial Electronics, 1995
The authors have developed a high-speed solenoid valve with a 1 ms switching time to control diesel engines electronically. In this paper, the authors focused their attention on developing the solenoid itself, investigating methods to be used for the fast operation of the solenoid valve.
