Free space optical (FSO) communication refers to the information transmission technology based on propagation of signals in space. FSO requires that transmitter and receiver directly see each other. High-altitude platforms (HAPs) have been proposed for carrying transceivers stratosphere. A multihop HAP network with links can relay traffic between ground nodes. In this study, we propose an end-t...

This thesis presents a new approach for enabling highly survivable secure communications within multi agent systems and combines two independent research projects aimed at validating this revolutionary approach. The traditional approach for providing secure communications, however efficient, presents a central point of failure and thus reduced survivability. The Medusa approach covered here, wh...

The ability to measure extracellular basal levels of neurotransmitters in the brain of awake animals allows for the determination of effects of different systemic challenges (pharmacological or physiological) to the CNS. For example, one can directly measure how the animal's midbrain dopamine projections respond to dopamine-releasing drugs like d-amphetamine or natural stimuli like food. In thi...
