Poster Session: Onu Engineering Freshman And Senior Design Projects, Keith Schimmel

Scholar Week 2016 - present

This poster session is held Friday, April 19, 4:45-6:15pm, with food served, in the Reed Hall of Science Tech Center.

The capstone engineering senior design projects at Olivet Nazarene University involve interdisciplinary engineering teams completing real-life projects sponsored by companies, mission organizations, and professional society competitions. The engineering first-year design projects at Olivet Nazarene University involve interdisciplinary engineering teams proposing product improvement designs, using Computer Aided Design (CAD) software. Posters for both the senior and freshman engineering design projects will be presented during this poster session.

Enhancing Fish Farming Sustainability In Guatemala: A Cost-Effective Oxygenation Solution, Olivia Wheeler, Creighton Seibeert, Carlos Gomez Gutierrez

Scholar Week 2016 - present

This project addresses a critical challenge faced by small-scale, family-owned fish farms in Guatemala, providing adequate oxygen to their fishponds due to the lack of reliable grid power and high energy costs. The primary goal is to design a sustainable and cost-effective solution that ensures continuous oxygenation within the range of 5-7 parts per million (ppm) of dissolved oxygen (DO). To achieve this, the solution must operate independently of grid power, withstand Guatemala's environmental conditions, and be replicable by local farmers for widespread accessibility. The holistic design objectives focus on boosting fish harvest yields, reducing operational costs, promoting sustainability, empowering …

Process Control Experiment: Automated Titration System, Marc Shuflit, Nathan Martin, Noelle Miller, Benjamin Tavares

Scholar Week 2016 - present

A titration experiment has been designed using a chemical reaction tank and implementing all the basic components found in automatic control systems. This system has been constructed using basic fluid flow hardware, control sensors and actuators, along with ladder logic programing for the Programmable Logic Controller (PLC) to automate an acid-base chemical titration. This system will be used in Olivet Nazarene University’s engineering labs to provide hands-on learning of state-of-the-art process technology.

Society Of Automotive Engineers Baja Vehicle Competition, Kevin Scott Leonard, Michael Roath, Matthew Bair, Ethan Burt, Jacob Burt, Jordan Evans, Jotham Drayton

Scholar Week 2016 - present

The Society of Automotive Engineers (SAE) Baja Senior Design Team is tasked with building a single person off-road vehicle to both perform in a competitive setting and appeal to the consumer market. Baja SAE gives students the first-hand challenge of pursuing their passion while managing real-life demands and priorities. Each team's goal is to design and build a prototype of an all-weather, rugged, single-seat, off-road recreational vehicle intended for sale to the nonprofessional weekend off-road enthusiast. The three main design objectives we believe are needed to reach our goals are for the vehicle to be durable, manufacturable, and serviceable. The …

Vocal Processing With Spectral Analysis, Brad Fitzgerald

Scholar Week 2016 - present

A method of vocal signal processing was examined to determine if principal component analysis of spectral data may be used to characterize differences between speakers and if these differences may be used to separate mixtures of vocal signals. Processing was done on a set of voice recordings from 30 different speakers in order to create a projection matrix which could be used by an algorithm to identify the source of an unknown recording from one of the 30 speakers. Two different identification algorithms were tested, both of which were generally unable to correctly identify the source of a single vocal …

Spectral Mixture Modeling Using Principle Component Analysis, Joseph S. Makarewicz, Heather D. Makarewicz

Scholar Week 2016 - present

A method for modeling mixtures between two end-member spectra using principle component analysis and linear regression was presented. The presentation included results from three binary mixture data sets including orthopyroxene-clinopyroxene, kaolinite-montmorillonite, and nontronite-ferrihydrite.

Weed And Crop Discrimination Through An Offline Computer Vision Algorithm, Phillip Jamison Putney

Scholar Week 2016 - present

With the recent global interest in organic farming and cultivation, many people are turning away from chemical-based herbicides and moving towards alternate methods to extirpate weeds living amongst their crops. Of the methods proposed, robotic weed detection and removal is the most promising because of its possibility to be completely autonomous. Several robust, fully-autonomous robots have been developed, although none have approved for commercial use. This paper proposes a weed and crop discrimination algorithm that utilizes an excessive green color filter paired with principal component analysis to detect spatial frequencies within an image corresponding to different types of weeds and …

Olivet Robotics, Alberto Escobar-Ruiz, Samantha Mclain, Caleb Seaton, Andrew Tipton

Scholar Week 2016 - present

It is the task of the senior design team to develop a plan that will result in the design, building, and testing of a robot. Members of the Robotics Club describe the base, arm, and programming in their design.

Sae Baja Data Acquisition System, Ryan Carl, Ryan Rose, Gabe Sevigny, Nathanael Smith

Scholar Week 2016 - present

The Olivet Nazarene University SAE Baja team designs a custom off-road vehicle every year to compete against teams from other schools at competitions throughout the year. The current car that the Baja team is working on needs some improvements, but they need some help gathering data to see where to make these improvements. In previous years, the Baja team would not have any feedback besides what they observed while driving, so this year they have tasked the SAE Baja Data Acquisition design group with the project of creating a sensor system and a data logging program to gather information that …
