this paper presents a method for damping of low frequency oscillations (lfo) in a power system. the powersystem contains static synchronous series compensators (sssc) which using a chaotic harmony searchalgorithm (chsa), optimizes the lead-lag damping stabilizer. in fact, the main target of this paper isoptimization of selected gains with the time domain-based objective function, which is solve...

A RE(rare earth)Ba2Cu3Ox (REBCO) high-temperature superconducting (HTS) coil is a promising candidate to achieve a nuclear magnetic resonance (NMR) magnet operated at a magnetic field >23.5 Tesla (T), i.e. 1 H NMR frequency of 1 GHz. We developed and tested a 400 MHz (9.39 T) NMR magnet using an REBCO inner coil. The system included a low-temperature superconducting (LTS) shim coil inside the R...

We discuss the generalizations of the MICZ-Kepler system (the system describing the motion of the charged particle in the field of Dirac dyon), to the curved spaces, arbitrary potentials and to the multi-dyon background. The integrable system describing the motion of the charged particle in the field of Dirac dyon (magnetic monopole carrying the electric charge) has been suggested independently...

[1] It has been demonstrated that terrestrial dust devils emit ULF magnetic radiation. On Mars, dust devils may also generate such magnetic emissions, which might be used as a hazard alert for manned missions. Specifically, grains in dust devils become charged via contact electrification, and it has been proposed that the cyclonic motion of these charged grains in the vortex wind fields account...

Neutrinos have no electric charge, but a magnetic field can indirectly affect neutrino properties and interactions through its effect on charged particles. After a brief field-theoretic discussion of charged particles in magnetic fields, we discuss two broad kinds of magnetic field effects on neutrinos. First, effects which come through virtual charged particles and alter neutrino properties. S...

An overview (but not comprehensive) list of intense slow muon physics programs at a future neutrino factory, ranging from particle physics, nuclear physics to applications, is given in Table 1, where programs are categorized into three groups, (1) precision measurements, (2) search for rare processes, and (3) application. Among the particle physics programs with muons [1], very important are (a...

differential steering of in-wheel electric vehicle provides the functions of both active steering and power assisted steering with the coupling control of force and displacement transfer characteristic of system. a collaborative optimization model of the differential power-assisted steering system of in-wheel electric vehicle is built, with steering economy as the main system optimization goal,...
