An Exploration Of Chaos In Electrical Circuits, Ryan Ann O'Connell
An Exploration Of Chaos In Electrical Circuits, Ryan Ann O'Connell
Senior Projects Spring 2016
This senior project investigates chaotic behavior and controlled chaos in electrical circuits. It primarily focuses on two types of circuits: one with a varicap diode and one with a operational amplifier based Chua diode. These are the non-linear elements of the circuit that produce chaotic behavior in voltage outputs. Attempts to get the circuits to function correctly were unsuccessful, but the project includes a theoretical investigation of the chaotic behavior of the circuits through bifurcations and period doubling, as well as ways this behavior could be theoretically controlled.

Photovoltaics: An Investigation Into The Origins Of Efficiency On All Scales, Jeremy Alexander Bannister
Senior Projects Spring 2016
This project is comprised of a set of parallel investigations, which share the common mo- tivation of increasing the efficiency of photovoltaics. First, the reader is introduced to core concepts of photovoltaic energy conversion via a semi-classical description of the phys- ical system. Second, a key player in photovoltaic efficiency calculations, the exciton, is discussed in greater quantum mechanical detail. The reader will be taken through a nu- merical derivation of the low-energy exciton states in various geometries, including a line segment, a circle and a sphere. These numerical calculations are done using Mathematica, a computer program which, due to …
