This poster presents the structural design of the Automated Parts Washer (APW), a senior capstone sponsored by Mary Kay and developed by engineering students at Texas Christian University. The APW is designed to provide an automated ultrasonic cleaning solution for cosmetic manufacturing components such as nozzles, caps, and trays. All structural components of the system have been modeled in Autodesk Inventor to enable a fully integrated digital design environment that supports visualization, dimensional coordination, and verification of system layout prior to fabrication. The washer frame utilizes 80/20 aluminum structural members, selected for their strength, modularity, and ease of assembly. This material choice provides flexibility in frame configuration, allowing rapid design iteration and future modification while maintaining robust structural support for the fluid-filled wash tank, ultrasonic hardware, and plumbing systems. The resulting design balances structural integrity, manufacturability, and adaptability for prototype construction and testing.

This paper presents the design and electrical performance analysis of a 10-MW
grid-connected photovoltaic (PV) power plant located west of Fort Worth, Texas, in a region selected for high solar irradiance, flat terrain, and transmission accessibility. Emphasis is placed on electrical system architecture, including module configuration,
DC string sizing, inverter selection, transformer integration, and interconnection with the utility grid. A single-axis tracking (panel pivoting) system is incorporated to maximize incident solar radiation and increase daily energy capture. Parametric studies
are performed on tilt angle, tracking strategy, module efficiency, and inverter performance to evaluate their influence on overall system output and electrical efficiency.

This project focuses on advancing the Coté Cruiser, an autopiloted Unmanned Surface Vehicle (USV) originally developed for automated sonar surveys. Building upon the initial iteration, which established the baseline for autonomous navigation and sonar data logging, this second iteration aims to enhance the craft’s power, sonar system, and real-time diagnostic capabilities. These upgrades provide a significant use case for the project sponsor, Freese and Nichols Inc., particularly in San Antonio, where underwater structural surveys of the river could potentially save the city nearly $2 million in damage funds.

This project focuses on the development of a biological and environmental sensor network to monitor the health and feeding behavior of oysters. This system utilizes a specialized cage design to consolidate oysters and sensors into a single, high-precision monitoring hub. The system correlates oyster valve gape activity - specifically feeding duration and frequency - with real-time water quality parameters such as salinity, dissolved oxygen, and chlorophyll-a. These upgrades provide a significant use case for the project sponsor, Freese and Nichols Inc., by establishing a scalable model for remote water quality monitoring that can be expanded across the Gulf and Atlantic coasts.

The increasing accumulation of plastic waste in landfills has created a need for innovative recycling solutions. This research explores the use of polyethylene terephthalate (PET), high-density polyethylene (HDPE), and polypropylene (PP) waste to produce plastic-sand composite bricks, inspired by the work of Gjenge Makers. In addition to evaluating the strength and durability of these bricks, the study analyzes the amount of recycled plastic incorporated into each and its potential to be remelted and reused, continuing its lifecycle. The plastic-sand composite bricks promote sustainable building practices while removing immense amounts of plastic from local landfills.
