Abstract The configuration, local motions, and related physics processes of the terrestrial magnetotail have been well studied, playing a key role in dynamics. But characteristics electron pitch-angle distribution (PAD), formation mechanisms, at different regions flapping were not pointed out. Here, we study current sheet crossing event detected by Magnetospheric Multiscale Mission inside magne...

[1] The effect of large amplitude chorus on energetic, radiation-belt electrons is evaluated using a general, relativistic, oblique, test-particle code. Three specific cases are examined: (A) Low-amplitude waves interacting at lowlatitudes exhibit the expected, linear scattering which leads to large-scale diffusive behavior. (B) Large-amplitude waves interacting at low-latitudes result in monot...

a detailed model of wind power station, including double fed induction generator, dfig is presented in this paper. two control mechanisms are included in the model. the inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. the outer control system is used for wind turbine pitch angle. pscad/emtdc is used ...

A technique obtaining a precise mapping of interactive effects in the pitch memory store is described. Subjects were required to compare two tones for pitch when these were separated by a 5-second interval during which six other tones were played. In the second serial position of the intervening sequence there was placed a tone whose pitch bore a critical relationship to the pitch of the first ...

Global crisis in financial, energy, together with climate and enviromental, has motivated word community to seek for alternative energy resourses, known as the new and renewable energy source to replace conventional widely used fossil energy. Wind energy, regarded as potential candidate of the clean alternative source that may help to solve the crisis. The development of the world’s wind turbin...

Several approaches for modelling the longitudinal aerodynamic coefficients of a fighter aircraft at high angles of attack, including the unsteady effects are presented. A traditional approach where the model of the coefficient arises in the form of the steady and unsteady effects, the unsteady effect being modelled by means of transfer functions. The second approach uses an internal variable de...

The NUADU (NeUtral Atom Detector Unit) experiment aboard TC-2 recorded, with high temporal and spatial resolution, 4π solid angle images of electrons (∼50– 125 keV) spiraling around geomagnetic field lines at high northern magnetic latitudes (L>10), during its in-orbit commissioning phase (September 2004). The ambient magnetic field, as well as electrons in other energy ranges, were simultaneou...
