Investigated in this thesis are the excitation and observation of Langmuir wave turbulence caused by the parametric decay instability (PDI) in high-frequency space plasma heating experiments conducted at the NSF/DoD High Frequency Active Auroral Research Program (HAARP) facility in Gakona, Alaska during the spring and summer of 2006. The PDI is the decay of an electromagnetic (EM) wave into an ...

During the last decade decade there has been a continually growing interest to the complex dusty plasma physics [1], [2]. A dusty plasma is a low temperature plasma with immersed dust grains of micrometer size. These grains are quickly charged under plasma exposition and become by a component of the plasma. The main features of this component are the very large and variable electric charge (up ...

Underwater Acoustic Tomography (AT) system transmits acoustic waves into the water. The AT systems continuously measure the physical characteristics of the flow in rivers, seas and the oceans. The AT systems are synchronized via a GPS clock connectied to the satellites. Hence, the systems transmit the acoustic waves at the same time. The systems record the arrival time of acoustic waves. After ...
