ABSTRACT Title of Thesis: FREE-SPACE OPTICAL COMMUNICAITONS THROUGH A FOREST CANOPY Clinton Lee Edwards‚ Master of Science‚ 2004 Thesis Directed By: Professor Christopher C. Davis‚ Department of Electrical and Computer Engineering This paper models the effects of the leaves of mature broadleaf trees on air-to-ground free-space optical (FSO) communication systems operating through the leaf canopy. Ecological radiation transfer models are considered and the concept of Leaf Area Index

in today’s academia. Many people have referred to him as one of the most important scientist that has ever lived. He is mostly known by his Theory of Universal Gravity and laws of motion‚ Newton’s laws‚ but he also influenced the areas of math and optics. Newton had a passion for alchemy and astrology. Today Newton’s laws of motion and gravity theory are still taught in schools as one of the most fundamental parts of physical science. Newton’s discoveries made an impact on academics and how the physical

Physics (from Ancient Greek: φύσις physis "nature") is a part of natural philosophy and a natural science that involves the study of matter[1] and its motion through space and time‚ along with related concepts such as energy and force.[2] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[3][4][5] Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy.[6] Over the last two millennia‚ physics

interest led me to take up Mathematics‚ Physics and Chemistry as my major subjects in high school. I was so intrigued by the working of electronic devices and the logics. This interest made me to take Electronic and TC Engineering. I would like to present my past performance as my credentials for my success in my future endeavors. My innate strength has been my quantitative and analytical abilities which instilled me a special interest for mathematical and physics. I had opted the same in my 10+2 with

reason within physics. How far do you agree with this? What is physics? It comes from the Greek word physis. “Physics is a natural science that involves the study of matter and its motion through space-time‚ along with related concepts such as energy and force”- Wikipedia. Physics is everything in this world. It is used to see how the universe behaves. This makes both reason and emotion a part of physics despite their importance in the proving of physics they can also be proved via physics. While emotion

of a gas giant planet called planet X ‚ where they evolve into an intelligent species which practises physics. Do you think their physical theories would be similar to ours‚ and if so in what ways would they be likely to be similar? Your answer will necessarily involve some speculation‚ but make sure it involves some careful argument as well. Theoretical physics is one of many braches of physics that uses different abstractions of physical things as well as mathematical models to rationalise and
