A new generation mechanism of butterfly pitch angle distributions of energetic ions: Multiple pitch angle scattering in the stretched magnetic field

Electron pitch angle distributions as indicators of magnetic field topology near Mars

[1] We have analyzed electron angular distributions recorded near Mars over a period of 7 years in order to constrain the topology of magnetic field lines near Mars. We used 63 million pitch angle distributions of 115 eV electrons measured at 400 km altitudes by the Mars Global Surveyor (MGS) spacecraft and classified them according to their shape. Closed magnetic field lines are associated wit...

Pitch angle scattering of an energetic magnetized particle by a circularly polarized electromagnetic wave

Pitch Angle Sca2tering of Cometary Ions into Monospherical and Bispherical Distributions

Low frequency magnetic fluctuations generated by solar wind/cometary ion distributions cause pitch-angle scattering of cometary ions. The nature of this pitch angle scattering is examined by means of one-dimensional hybrid simulations, in which newborn ions are created at a constant rate, and for various injection angles, o•, relative to the magnetic field. Pitch angie scattering in the quasipe...

Different Types of Pitch Angle Control Strategies Used in Wind Turbine System Applications

The most common controller in wind turbine is the blade pitch angle control in order to get the desired power. Controlling the pitch angle in wind turbines has a direct impact on the dynamic performance of the machine and fluct­uat­io­ns in the power systems. Due to constant changes in wind speed, the wind turbines are of nonlinear and multivariate system. The design of a controller that can ad...

Transcription and the Pitch Angle of DNA

The question of the value of the pitch angle of DNA is visited from the perspective of a geometrical analysis of transcription. It is suggested that for transcription to be possible, the pitch angle of B-DNA must be smaller than the angle of zero-twist. At the zero-twist angle the double helix is maximally rotated and its strain-twist coupling vanishes. A numerical estimate of the pitch angle f...
