   This Lecture contains a brief discussion of the physical processes involved in the production of the auroral lights, the di erent classes of auroral ra-diation associated with various precipitating particle populations, the existence of eld-aligned currents and potential drops in the auroral regions, auroral substorms, and the auroral electrojets.

   The aurorae are mainly caused by high-energy electrons originating in the sun and entering the earth’s atmosphere in narrow regions centered on the magnetic poles. These electrons collide with atmospheric atoms, which are excited to higher energy levels.

   In this paper, we propose a model for visualizing the aurora borealis using data gathered from satellite observations. The observed data represents the electric fields and the distributions of Field-Aligned Current (FAC) in high latitudes.

   15 gru 2009 · The goal of a PDE (Pulse Detonation Engine) is to harness the power of detonations to propel a vehicle forward. PDEs are being investigated because they can provide higher burn efficiencies over the entire Mach number range of gas turbine engines. The concept of a PDE is simple: inject fuel and oxidizer, detonate, expel gases, repeat.
