Bonded Magnets in PM-Assisted Synchronous Reluctance Machines: Performance Dependence on the Production Technology

, 2019
The versatility and robustness with the low costs, characterize the synchronous reluctance SRM machines. On the other hand, some drawbacks limit the potential of such machines.

Synchronous Machines: a Traced Category

, 2012
Synchronous programming languages have been extensively used in the area of critical embedded systems. Synchronous machines, a specific class of labelled transition systems, are often used to give denotational semantics of these languages.

Speedups of deterministic machines by synchronous parallel machines

Proceedings of the fifteenth annual ACM symposium on Theory of computing - STOC '83, 1983
The paper presents new speedups of deterministic multitape Turing machines by both fixed and variable structure parallel machines. Namely, it is shown that DTIME(T)\(\subseteq ATIME(T/\log T)\) and DTIME(T)\(\subseteq PRAM\)-time(\(\sqrt{T})\). These improve many previously known results.

Design and Analysis of a Self-Excited Brushless Wound-Field Synchronous Machine With Reduced Torque Ripple

International Transactions on Electrical Energy Systems
Permanent magnet synchronous machines are commonly employed in variable-speed applications because they offer high efficiency, easy control, robust construction, and do not require external field excitation.

Decomposition of synchronous sequential machines into synchronous and asynchronous submachines

, 1967
The problem of the decomposition of a sequential machine into smaller submachines has been treated by Hartmanis (1961, 1962) through the algebra of partitions.
