Student Design Projects Description

I. ME Projects

A. Disaster Relief Shelter. Samaritan’s Purse and John Brown University sponsor a national competition to design and build a prototype of a disaster response shelter for rapid deployment and set-up, to be used by aid organizations responding to natural or man-made disasters. The refugee crisis currently unfolding in the Middle East and Eastern Europe provides an illustration of a specific disaster type and location as well as the cultural considerations which should be incorporated in the shelter. The goal of this Senior Design project is to design, analyze, and manufacture a disaster relief shelter subject to simulated high winds, various temperature conditions, and earthquake activity. In addition, the students' design must consider the structure's packaging, weight, cost, and assembly.

B. Boat for Dutch Solar Challenge (DSC) of 2016. Design and build a boat which flies on hydrofoils.

C. Spinal Implant Design for Subsidence Prevention. Discover how design features and surgical installation procedures affect subsidence of artificial discs and fusion devices into lumbar vertebral bodies. Additionally, provide recommendations for design and/or procedural changes that show promise in reducing subsidence.

D. Wooden Bicycle. Design and manufacture three different types of wooden bikes by modeling them in Solidworks and completing FEA and various testing. Additionally, utilize the CNC router and lean manufacturing techniques to decrease the manufacturing time of the bikes. Finally, test the plywood to determine whether these materials offer advantages in the production process.

E. Over-Expanded Cycle Internal Combustion Engine. Improve the fuel-conversion efficiency of the internal combustion engine using an over-expansion eycle (OEC). Modify the existing prototype to accomplish this task as well as test it on a dynamometer. Continue to update the thermodynamic model of the engine as changes are made.

F. Engineering Projects Lab Solar Fan. The overall goal of this project was to use solar power to run a fan or system of fans in order to bring the comfort level of the Engineering Projects Lab to acceptable levels. In reaching this goal, the main objectives were to identify what it means to have a comfortable space, determine the air speed needed to achieve that level of comfort, determine how much power is available from the solar panels, use fan theory and Computational Fluid Dynamics to design a fan within the found limitations, identify the ideal location and number of fans within the building, and finally predict the performance of the system using CFD.

G. Design, Modeling, and Testing of a Cyclogyro. The overall goal of our project is to design, build, and test a cyclogyro rotor, and in so doing make predictions based on the theory and the Computational Fluid Dynamic (CFD) analysis, and compare these predictions with our testing results in order to improve the design.
Main Objectives
1. Create a Matlab program to calculate thrust forces, torque, and power.
2. Use CFD to predict the performance of the cyclogyro.
3. Design a cyclogyro rotor and blades.
4. Create manufacturing and building instructions.
5. Manufacture the rotor and blades with composites like carbon fiber for as many as possible parts.
6. Design a testing apparatus.
7. Design methods of measuring rotational speed, lift, and torque.

H. SAE Aero Design: Design/Build/Fly an RC airplane in the advanced class SAE aero design competition. The competion rules require that the airplane drop a package within a target using real time telemetry data.

K. 3D printing for Tissue Engineering Applications: Biomedical engineering students are working to develop 3D printed scaffolds that are conducive to growing cells for large bone defect and ACL applications.

J. Attached Flow. The main goal of this senior design team is to design an ultra-low high mileage car body with enclosed wheels. To achieve this goal, the drag force on the body will be minimized within the competition constraints.

II. EE/Computer E Projects.
A. Swarm Robots.
Continuation of a project to design a set of small, low-cost, independent robots that will collectively function as a swarm to accomplish tasks.

B. RoboBoat.
Continuation of an ongoing project to design and implement an autonomous boat to compete in the international Roboboat competition held annually in Virginia Beach, VA. This year we are including an autonomous flying drone that will launch from and return to the boat during the competition to complete one of the competition challenges.

C. Android Home Automation.
To design and construct a system for monitoring and controlling home security functions and appliances through an Android device through the internet.

D. Bluetooth Oscilloscope.
To design and construct a two-channel oscilloscope that utilizes Bluetooth technology for the display and control of the scope using an Android device. The signal collection and processing will be accomplished through a small instrument with no display or controls, leaving all of the user interface on the Android device under software control.

E. Payload Delivery System.
To design and implement a telemetry system for a small remotely controlled aircraft. The system will provide flight information such as altitude, and speed as well as a live video feed to a ground based operator. The system will inform the operator so that a flight pass can be made and a payload accurately delivered (dropped) to the ground.

F. Wireless Audio Link.
To design and implement a system to replace the cord typically used to connect an electric guitar to the foot-controlled effects system with a digital radio interface. The device is to have a form factor similar to a belt-mounted microphone thus freeing the guitarist from being tethered to the sound system.

G. Solar Boat Electronics.
To design and implement a power control system for a solar-powered boat. The system will manage the charging and discharging of the battery system and provide the operator with real-time information on the state of the system.

H. Motor Controller.
To design and implement an electric motor controller for use in an all-electric, or hybrid-electric car.

I. AC Buck Regulator.
Continuation of a project to design and build a system that regulates an AC supply voltage to remain within specified limits. The goal is to better manage "dirty power" that exists in developing countries where the AC power is not well regulated.

J. Switched Transformer Regulator.
To design and implement an AC voltage regulation system utilizing a multi-tapped transformer. This system will consist of electronics that sense the incoming "dirty" AC voltage and select the appropriate tap on the transformer so that the output voltage remains within an allowable range. The system must respond within on cycle of the AC, and be able to shut down completely if the input voltage strays outside of an absolute minimum or maximum voltage.

K. Body Area Network.
To design and build a wearable system that is ideally imbedded into a Tee-shirt. The system is to monitor and record biometric data such as EKG, temperature, and O2 saturation levels using non-invasive techniques and transmit the data through Bluetooth to an Android device where the data can be recorded and displayed.

III. Computer Science Projects.
A. Bible Story Mobile Application. The goal of the project is to be able to use templates of still picture Bible stories and convert them into illustrated, dramatized audio books (videos) in languages where people do not have access to Scripture and may not have a written language. Bilingual speakers should be able to translate the story orally into their mother tongue, have the translation checked by others, record a dramatic version of the story, and export the resulting video. Given a template of a Bible story in a gateway language, the app should help produce a shareable video of the Bible story in the mother tongue.

B. CUSigns. CUSigns is a new solution to digital signage for Cedarville University. The IT Department requested that we create software to replace the existing solution which is called Concerto. Concerto is not very user friendly and does not allow for campus wide emergency notifications, videos, RSS feeds, weather, time or date to be displayed on the screens. Concerto also had a poor randomization algorithm that often led to the same slide being shown twice in a row. CUSigns will be a new solution for digital signage that will overcome the limitations that Concerto posed.

C. AFRL Hololens Project. The project is meant to be a proof of concept for allowing a remote expert to communicate with and assist a field technician in completing procedures with which the technician may be unfamiliar. The model test scenario assumes the remote expert is equipped with a Microsoft (MS) Surface Pro and the field technician is equipped with a Microsoft Hololens.

D. CedarLogic 2.0. This project intends to update the CedarLogic application (first developed in 2006) for execution on Windows 10 devices, and expand the supported operating systems to include linux and MAC O/S. The project also intends to improve CedarLogic by allowing hierarchical design of circuits.
