Solar Generation's Impact On Fault Current, Kody Heppner

Electrical Engineering

California is paving the road for other states with the capacity of solar installations for residential and commercial entities. The added capacity of solar generation to the state's electric grid has an impact on power flow and fault currents. This project looks at the impact of solar installations on fault currents. Feeders with added residential rooftop solar and larger commercial solar installations may impact the system differently than a large, utility-sized solar installation. This project looks at the impact of both cases on the magnitude of fault current during many different fault types and locations that can occur within a …

Semi-Automated Test Generation With Spest, Adam Mozek

Computer Science and Software Engineering

Automated black box test generation is a useful tool for developers that allows them to

quickly generate a large number of tests with a wide range of values tested. The current most

popular tool for black box test generation in Java, JML, is lacking in a number of features.

SPEST aims to improve upon existing tools, and provide a black box test generation tool that

can create human readable tests from simple pre and post conditions added as comments to

the Java source code.

PolySat is a student-run, Cal Poly research program in which students develop small satellites, known as CubeSats, to be sent into space. Since the start of the program in 2000, PolySat has developed eight 10cm x 10cm x10cm CubeSats. Recently, the team has developed two satellites of double, and triple, that size for NASA-KSC & AI-Solutions and the National Science Foundation. The recent volumetric expansion has been driven by high demand for further satellite functionality, which necessitates large power generation capabilities. To remain competitive in the growing CubeSat industry, PolySat must develop a platform that can provide enough power to …

Fluid Midi Ribbon Guitar, Noah Baker

Electrical Engineering

This project was developed to create a new electronic instrument based off of a guitar. The design will give the user more chord combinations than are available on a typical guitar, the ability to retune each “string”, and customizable MIDI controller outputs, while trying to retain a similar playing style. The initial design for this project included implementing an onboard synthesizer (analog or digital). This idea was scrapped for time and cost considerations and replaced with MIDI output which will yield user customizable sound through virtual instruments, such as Massive.
