Effect Of Environmental And Ultraviolet Degradation On The Albedo Of Polyethylene Sheet Materials For Improved Energy Harvesting By Bifacial Photovoltaic Power Plants, William A. Jang, Roxy H. Jackson-Gain

Materials Engineering

Solar energy farms typically utilize monofacial photovoltaic (mPV) cells in their arrays to capture direct sunlight to produce renewable energy. However, the efficiency of these farms can be increased by 2 – 6% through the implementation of bifacial photovoltaic cells (bPV). These bPV cells function by capturing incident ultraviolet (UV) light energy that is reflected off the surface to increase its overall energy production. The amount of UV energy that is reflected is dependent on the albedo value of surface, which is a measure of energy reflectance. In this study, samples of unreinforced polyethylene (PE), scrim-reinforced polyethylene (SR-PE), and woven …

Benefits Of Having A Disability Cultural Center At Cal Poly, Chau Nguyen

Political Science

All colleges and universities in the United States are legally required to accommodate their students with disabilities. However, many schools do not support their disabled student body in ways that go beyond what they are legally required to provide under the Americans with Disabilities Act (ADA) and Section 504 of the Rehabilitation Act. Though every university and college in the United States has a dedicated ADA compliance office, students with disabilities still express that their holistic needs are unmet and that they feel unsupported by their schools. Establishing Disability Cultural Programs and Centers is one method that colleges and universities …

A Comparison Of Carbon-Based Calculators For Building Construction, Adam J. Walsh

Construction Management

The construction industry has a significant environmental impact, contributing to energy usage, carbon emissions, and waste generation. Efforts to promote sustainability and reduce this impact have emerged, with organizations like the U.S. Green Building Council and the U.S. Environmental Protection Agency leading the way. One key aspect of sustainable construction is the use of carbon calculators, web-based tools that estimate and track carbon emissions throughout the building process. These calculators consider factors such as energy consumption, transportation, and waste disposal to provide a holistic view of a building's carbon footprint. However, there are challenges and limitations associated with these calculators, …

Comparative Analysis Of Construction Scheduling: Consultant-Led Vs. Project Team-Led Approaches, Elijah J. Stennett

Construction Management

Efficient and accurate construction scheduling plays a pivotal role in the successful completion of construction projects. Most construction companies understand this importance, and they heavily rely on their schedulers. This research paper investigates the advantages and drawbacks of employing a consultant-led scheduling approach compared to a scheduling process managed solely by the project team. To assess the effectiveness of the two scheduling approaches, two companies and their scheduling practices were analyzed, and project management individuals were interviewed from each company. The findings reveal that a consultant-led approach brings specialized expertise in scheduling software, provides advantages in court litigation, and provides …

Distributed Control Of Servicing Satellite Fleet Using Horizon Simulation Framework, Scott Plantenga

Master's Theses

On-orbit satellite servicing is critical to maximizing space utilization and sustainability and is of growing interest for commercial, civil, and defense applications. Reliance on astronauts or anchored robotic arms for the servicing of next-generation large, complex space structures operating beyond Low Earth Orbit is impractical. Substantial literature has investigated the mission design and analysis of robotic servicing missions that utilize a single servicing satellite to approach and service a single target satellite. This motivates the present research to investigate a fleet of servicing satellites performing several operations for a large, central space structure.

This research leverages a distributed control approach, …
