Structural Health Monitoring Of Composite Parts: A Review, Jacob Pessin
Structural Health Monitoring Of Composite Parts: A Review, Jacob Pessin
Honors Theses
Structural health monitoring has the potential to allow composite structures to be more reliable and safer, then by using more traditional damage assessment techniques. Structural health monitoring (SHM) utilizes individual sensor units that are placed throughout the load bearing sections of a structure and gather data that is used for stress analysis and damage detection. Statistical time based algorithms are used to analyze collected data and determine both damage size and probable location from within the structure. While traditional calculations and life span analysis can be done for structures made of isotropic materials such as steel or other metals, composites …
Design Of Natural Composite I-Beam For Sampe 2019, Brian Harkness
Design Of Natural Composite I-Beam For Sampe 2019, Brian Harkness
Honors Theses
In recent years, the demand for high performance, lightweight, fiber-reinforced composites have grown substantially. Fiberglass and carbon fiber have exemplary material properties that meet the demand and have set the industry standard for performance materials. Although these materials meet their design function, they suffer from high environmental impacts throughout their life cycle and are not cost effective to produce. Flax fiber composites have comparable properties to fiberglass but can be produced more efficiently and production requires much less energy consumption. Flax is a readily available, renewable material that will easily biodegrade once it is the end of its useful life …
Thermoplastic Composite Heat Recovery Ventilator, Keegan Guinn
Thermoplastic Composite Heat Recovery Ventilator, Keegan Guinn
Honors Theses
Heat recovery ventilation continues to increase in importance as building codes mandate reduced air infiltration and increased energy efficiency. Heat recovery ventilators are able to reduce building heating and cooling loads by transferring heat between the exiting air and incoming ventilation air. In the role of heat recovery ventilation, additively manufactured polymer composite heat recovery ventilators offer significant advantages over traditionally manufactured metallic alloy heat recovery ventilators. Through the implementation of additive manufacturing, the internal geometry of the heat recovery ventilator can be optimized to decrease the head loss across the system and features to improve heat transfer such as …
The Effect Of Soil Saturation On The Heat Transfer Rate In A Controlled Environment For Application To Ground Source Heat Pumps, William Barnard
The Effect Of Soil Saturation On The Heat Transfer Rate In A Controlled Environment For Application To Ground Source Heat Pumps, William Barnard
Honors Theses
With the worldwide push for environmentally friendly technology, the topic of geothermal systems has only become more important. Ground Source Heat Pumps (GSHPs) are heat pumps that take advantage of the natural temperature difference between the soil and the air to decrease the amount of power necessary to heat an area. A GSHP has been shown to be capable of increasing efficiency by 3 or 4 times the amount of a conventional heating and cooling system [4]. To take advantage of the full capabilities of a GSHP, one needs to understand what factors can increase or decrease efficiency. While research …
Analysis And Proposed Improvement Of Hamilton County Vw Elab Equipment, Hiroshi Yanagida
Analysis And Proposed Improvement Of Hamilton County Vw Elab Equipment, Hiroshi Yanagida
Honors Theses
Digital fabrication laboratories have revolutionized project based learning within K-12 STEAM education curriculum. However, classroom utilization of the labs often requires excessive machine hours to accomplish, and this often leads to rapid machine depreciation and disrepair. Many educators do not have the time to repair their equipment while developing curriculum and engaging with their students. This study focuses on building a repair history for common digital fabrication equipment, which includes Prusa i3 Mk2S FDM 3D printers, laser cutters, and CNC routers. Data were collected over a 6 month period to find which machines encountered the most issues. The 3D printers …
The Analysis Of Erlanger Hospital’S Suture Inventory Management Operations, Amanda George
The Analysis Of Erlanger Hospital’S Suture Inventory Management Operations, Amanda George
Honors Theses
This paper evaluates the impact of using mechanical engineering and operations management principles to an inventory management system in Erlanger Hospital. Erlanger Hospital is a local, nonprofit hospital system in Chattanooga. Erlanger serves as a tertiary referral hospital and a Level I Trauma Center in the region. Therefore, they are heavily depended on during times of crisis or emergency [2]. This study focuses specifically on reducing the loss and ultimate waste of sutures across Erlanger’s surgery wing. A criteria for the appraisal of using mechanical and manufacturing engineering to improve the current system is established based on existing data regarding …
Computational Simulation Of The Paw-04 Nozzle Configuration, Juan Hernandez
Computational Simulation Of The Paw-04 Nozzle Configuration, Juan Hernandez
Honors Theses
The research was based on the 4th Propulsion Aerodynamics Workshop which was organized by the American Institute of Aeronautics and Astronautics (AIAA) Air Breathing Propulsion System Integration Technical Committee and its objective was to assess the accuracy and numerical prediction capabilities of Computational Fluid Dynamics (CFD). It focused on the work of Behrouzi and McGuirk where they tested two different nozzle configurations under set boundary conditions. The nozzle configurations included a high aspect ratio rectangular nozzle with a clean exit and the same nozzle with an aft-deck attached to the exit. Three different unstructured grids were generated for the clean …
3d Printing Robotic Arm On Linear Rails, Thomas T. Steele
3d Printing Robotic Arm On Linear Rails, Thomas T. Steele
Honors Theses
Typical 3D printers are bound by the printing bed volume relative to the printer frame volume. A 3D printing robotic arm set upon sliding linear rails was designed and built. The arm was 3D printed with a traditional 3D printer designed using Autodesk Inventor. This product reduces printer size while increasing bed area and reduces cost with use of 3D printed parts.

Energy Analysis And Orbit Simulation Of Actuating Cubesat Solar Arrays, Justin T. Ehren
Honors Theses
CubeSats are used in space research to explore new technologies and detect data to gain a better understanding of various areas of research and subjects affecting human life. CubeSats rely on a solar array to generate energy from the sun and perform their various functions in space. This research studies the energy capturing potential of various solar array configurations and positioning devices for CubeSats. The location and orientation of a CubeSat is simulated with MATLAB for both geo-synchronous and sunsynchronous orbits. Two degree-of-freedom (DoF) positioning devices are sufficient to continuously adjust the photovoltaic array to face towards the sun. Lower …
Towards A Pre-Processing Algorithm For Automated Arrhythmia Detection, Sarah Miller
Towards A Pre-Processing Algorithm For Automated Arrhythmia Detection, Sarah Miller
Honors Theses
There are a variety of different wearable fitness/cardiac monitoring devices that are currently used in many people’s day to day life. The primary cardiac function of these devices is to monitor heart rate, however we believe that they could be utilized to detect different forms of arrhythmia. In order to categorize and identify different forms of arrhythmia, we are utilizing published EKG data sets from existing databases as a basis for machine learning. The challenge that comes from the existing data sets is that the format they present the data in does not lend itself to machine learning, which requires …

Design & Evaluation Of Cooling Systems For Photovoltaic Modules, Peter Leary
Honors Theses
There is a persistent need for further development and implementation of renewable energy sources, such as wind and solar. Due to the increase in global population, the disappearance of fossil fuels, and the reality of climate change, renewable power is needed now more than ever. One such renewable power technology is solar photovoltaic, otherwise known as PV. These modules work via silicon cells which are as semiconductors, outputting electrical energy when incident with solar radiation. This is done by separating electrons and protons within the cell. One of the largest issues with PV technology is that there is a linear …
