Abstract Summary:  Diabetes remains a significant challenge for modern society, and the growing number of diabetic patients requires a constant supply of insulin. Current estimates suggest that 7 million liters(7,630,000 kg) per year are produced annually amongst the three major suppliers Eli Lilly, Novo Nordisk, and Sanofi, but this amount is insufficient to address global insulin demand with a further emphasis on reduced patient costs. As such, there is a need to develop new and/or supplemental methods for producing and distributing insulin efficiently. This study focuses on the proposed use of a genetically engineered strand of Escherichia coli bacteria that produces a protein sequence containing a fusion protein form of human insulin. This fusion protein is then isolated, further processed, and purified in a form equivalent to that produced in the body for distribution. Our approach involves the use of engineering design fundamentals such as heat and material balances, heuristics, economic analyses, and process safety assessment and management associated with the production of 3600 kg of insulin annually, corresponding to 0.05% of the global demand.

Abstract Summary:  With diabetes on the rise, the demand for insulin is higher than ever before. There are currently very few large insulin producers, leading to a great opportunity to enter the market. Out of the approximately 422 million people in the world living with diabetes, 8.4 million have type 1 diabetes, which requires insulin for them to live. Some calculations determined that the yearly insulin requirement for just these 8.4 million people is around 4923.9 kg/year. The process explored is based on the “proinsulin method” and aims to produce 2215.8 kg/year, which is 45% of the total yearly insulin required by type 1 diabetics. The process involves the use of an innocuous E. coli strain that produces inclusion bodies with the desired proinsulin. The process utilizes a series of reactions and purification steps to transform the proinsulin and isolate the resulting insulin so that it can be utilized by the human body. This process concept provides a large opportunity and likelihood of success for the prospective plant within the growing industry. This current production process taps into less than 3% of the global market for insulin production. To address the ever-increasing rates of diabetes, it is also suggested that the company use the profits from this initial insulin production facility to fund additional facilities in the future, increasing profits and capturing a larger portion of the market. In this presentation, the team will also discuss both the economic analysis and the optimization of the proposed process.

Abstract Summary:  The development of 3-D printed cement homes has given an opportunity of providing affordable housing and may contribute to a solution to fight the rising cost of homes. The growth of the housing market has brought attention to 3-D printing homes, which led companies to create new ventures on developing 3-D printing technologies for construction. Yet, few companies address the low-income housing sector and are not able to keep up with the demand of the market. This project specifies the materials to be used in the cement mixture, the process flow, and the rate of extrusion as well as the costs and power consumption required to build a 3D printed home using cement-based materials. The process consists of a liquid pumping system, cement pneumatic conveyor, mixer, paste pump, and a printing nozzle. The analysis accounts for the overall heat and material balance as well as some tradeoffs and constraints that might be associated with them. Therefore, the project analyzes how 3-D printing can be implemented to address issues regarding design, community, and cost for an affordable three-bedroom and two-bathroom house.

Abstract Summary:  The modern paradigm shift towards the abatement of greenhouse gas emissions in the last 50 years has accelerated the transition to renewable energy sources, prompting the energy sector to explore sustainable and technically feasible solutions to mitigate the effects of climate change. The energy industry is now facing the daunting challenge of reducing its carbon footprint, a problem that would require nothing short of a complete transformation in global energy practices. One such alternative is utilizing iron powder as a renewable fuel in industrial applications. Backed by an innovative iron oxide reduction process, the carbon-free fuel could contribute significantly to the goal of reaching carbon neutrality. Fine iron powder mixed with oxygen is highly combustible, and unlike a carbon-based fuel that oxidizes into CO2, iron fuel oxidizes into Fe2O3 or simply rust. Via renewably-sourced green hydrogen, the iron oxide could subsequently be reduced back into useable iron powder in a circular process that operates analogously to a rechargeable battery – storing energy in the form of iron oxide for later use as demand increases or decreases. The only two byproducts of the process are 1) the heat captured to generate electricity and 2) the rust itself, thus producing no carbon waste products. Although today’s energy requirements still need to be met, it is imperative to evaluate alternative energy sources that are simultaneously sustainable on both the environmental and economic front and will meet tomorrow’s energy demands. Reducing the iron oxide via hydrogen from renewable electrolysis processes enables the entire process to be zero-carbon and presents a transformative opportunity to address the critical challenge of sustainable energy storage on an industrial scale.

Abstract Summary:  A multi-stage solar desalination still is designed to produce fresh water for an average family in developing countries. It is made of affordable materials and intended to be reused for several years. This apparatus utilizes solar energy as the source of heat. At each stage, seawater is absorbed via capillary action - it is then vaporized, and the freshwater is condensed on a wax-coated aluminum sheet.

The product being developed by this team improves the previously reported model by MIT/UC. The improved design offers a different geometry which is 1 meter wide, 10 centimeters tall, and 6.1 centimeters in depth. Designing the desalinator with these dimensions will produce an increased amount of freshwater while maintaining the efficiency of capillary action. The proposed design offers the advantage of higher efficiency and greater freshwater production. Updating this MIT/UC desalinator design will produce 2.7 liters of potable water per hour. The MIT/UC model produces 0.0578 liters of fresh water per hour. This volumetric flow rate improvement, along with using reusable materials, will benefit the communities depending on this desalinator for potable drinking water.

Abstract Summary:  The production of superior quality brass-plated steel tire wire is necessary in order to meet the demand for safe and sturdy tires due to the millions of automobiles and trucks on the roads annually. The proposed production facility will have a daily production capacity of 200 tons of brass-plated steel wire per day. The brass coating has been proven to make the tires more durable to roadway stressors. The brass layer allows for better adhesion to the rubber tire wall as well. Steel wire will be sent through a heating and cooling mechanism to achieve the desired grain structure. During this step, oxides form on the surface of the steel wire. The steel wire then gets sent through a hydrochloric acid pickling bath to remove oxides and other contaminants. The steel wire is then sent through a copper electroplating bath to obtain a layer of copper around the outside of the wire. The wire is rinsed before entering the next step of the process, which is a zinc electroplating bath. The wire is rinsed again before entering the last steps of the process where the zinc and copper layers get thermally diffused and heated to form a brass coating around the wire. Current industry processes sufficiently produce superior quality tires; however, the process uses a large amount of hydrochloric acid for pickling the steel and generates HCl fumes as a result. We are proposing a process that incorporates a hydrochloric acid regeneration step to significantly reduce the amount of HCl being purchased and transported to the facility annually, which will also reduce annual HCl costs.

Abstract Summary:  This project aims to develop a sustainable process design for polyethylene terephthalate (PET) fiber production, using Aspen Tech modeling software and MATLAB. The process design involves three critical steps: esterification, polymerization, and spinning. A comprehensive Aspen Tech model and MATLAB simulation are developed to simulate these processes and optimize the operating parameters, such as temperature, pressure, and feed ratio, to minimize energy consumption and waste generation. The model is validated by comparing the simulation results with experimental data from literature sources. The optimized process design achieves a desired one million pounds of fiber production per week with fiber being characterized by a denier of 2 with reduced environmental impact and cost. The outcome of this project provides a sustainable approach to PET fiber production that can contribute to the circular economy.

Abstract Summary:  The reclamation of process water is crucial for industries to reduce their water footprint and minimize the impact of their operations on the environment. Reverse osmosis (RO) and forward osmosis (FO) are two membrane-based technologies that have been widely investigated for process water reclamation. The effect of operational parameters such as feedwater composition, flow rate, and pressure on the performance of both processes were investigated. Results showed that both RO and FO processes were effective in removing a wide range of contaminants from the process water. However, FO demonstrated a higher rejection rate of dissolved solids and organic matter than RO. Furthermore, FO exhibited a lower fouling rate than RO, leading to a longer operational lifetime of the FO membrane. Overall energy requirements and economic outlook for the process were examined, and the possibility for beneficially reusing some of the process water constituents was considered. In conclusion, FO showed superior performance in terms of water quality and membrane fouling, making it a more favorable option for process water reclamation. The findings of this research have important implications for industries seeking to implement sustainable water management practices.

Abstract Summary: The goal of this project is a replicable device that accepts and operates multiple air quality sensors independently with a selection of interchangeable sensor options for local data collection. Air quality is vital to maintaining life on Earth. Poor air quality can result in a slew of health problems such as heart disease and lung cancer. In the modern age, humanity pushes the levels of pollution in the world to unprecedented levels as compared to the pre-industrial era. This pollution affects the very air that all living things rely on to survive. This perspective on the negative repercussions of polluting the air and Earth is what led to this team’s proposition of a device that allows everyday citizens to see what pollutants blight their communities.

There are already services that exist to alleviate this problem, however, the services do not fulfill the solution to a high degree. The biggest of these services would be the Air Quality Index (AQI) provided by the United States Environmental Protection Agency. The AQI takes in data from sensors placed systematically all across the country and in highly populated areas. This data is then aggregated together to fill in any regions that were not explicitly sampled from a sensor directly. The issue derives from that last sentence. Because it is not reasonable or cost-effective for these services to place sensors everywhere, the readings that are received from these sensors may not be accurate in any given place. For a community wanting a detailed view into the air quality of their chosen area, they would require more concrete sources of data. It is here where the team’s proposed device comes in to provide an easy-to-use, solar-powered, easily replicable, and low-cost modular system that uses multiple sensors to gather data on different pollutants.

Abstract Summary: Every year hundreds of students require various devices for their ECE (Electrical and Computer Engineering) classes. These specific devices are provided by the College of Engineering and are rented out to students through the ECE office. Typically, in the first month of a semester, students attempt to check out on average 50 devices in a day from the Office. This capstone project will focus on designing and implementing a vending machine that can distribute devices out to students while recording which students have checked out a device. The finished product will be a vending machine with the functionality to vend the needed specific devices to students. A student can enter their information into the machine, and the machine will record who has checked out their respective device(s). The machine will use a motor to rotate a device to the door for a student to remove that has LEDs (Light Emitting Diode) which will allow students to see and determine which device is the one they should remove. The student will then take the device and shut the door for the next student.

Abstract Summary: During the Fall 2022 semester at Tennessee Technological University, the Capstone Design Project Team 4 collaborated to further enhance the riding experience offered by the existing Mario Kart Bike design. Team 4’s design adds a variable of resistance for two modes of operation: the Mario Kart Game Simulation and a Ride Replay Simulation (RRS). The RRS is a pre-recorded trail ride simulation using data from an actual trail in Cookeville, TN.

Improvements to the previous iteration of the Mario Kart Bike offer new dimensions of realism by adding a more dynamic resistance system, while the RRS will enable users to record an actual bike ride and then replay it later indoors. Using data gathered from various sensors and an internal physics engine, the RRS processing subsystem will calculate whether to speed up or slow down video playback based on the speed the user is pedaling, and it will determine the appropriate resistance to apply.

The streamlined resistance system design will replace the cumbersome motor with a linear motor attached to an array of N52 neodymium magnets, located perpendicular to a conductive flywheel to generate eddy currents. Opposing magnetic fields will generate braking torque in the flywheel, which will be transferred to the real bike wheel. This braking torque will function as the resistance felt by the user. The magnetic resistance system will utilize 85 states, creating a smooth and realistic replay. The new resistance system will also work in the original Mario Kart Bike Mode, using Nintendo Switch rumble states to determine the appropriate resistance to apply.

Abstract Summary: Commuter students at Tennessee Technological University in Cookeville, TN, frequently face difficulties to find open parking spots in lots during peak hours of the school day, which causes tardiness to class to be a common occurrence. Commuters typically have a lack of foreknowledge of the availability of parking spots across lots prior to entering campus. Due to current products on the market either being very expensive or not fully feasible or effective for Tennessee Tech’s parking lots, an in-house parking lot monitoring system designed by students in Tennessee Tech’s College of Engineering was proposed to provide a more cost-effective solution. A parking lot monitoring system has been designed to utilize sensor technology to track and frequently update the number of available parking spots so that students can know the occupancy of a parking lot in real-time. The data from the sensor technology would be displayed on a mobile application that students can download to view real-time statistics and previous history of parking lot occupancy, as well as on a ground-level display board. This project involves interdisciplinary collaboration between teams from the Department of Electrical and Computer Engineering and the Department of Computer Science while under the direction of the Naval Sea Systems Command (NAVSEA) in Dahlgren, VA.

Abstract Summary: There is a need for additive manufacturing research because of the rapid growth of the process within the manufacturing engineering industry. Aluminum, in specific, obtains very easily manipulative properties that allow it to be reconstructed and shaped using a 3D printer. With the ability to 3D print metal objects, variables such as cost and time are reduced, which will give way for much more future research to be conducted. The aluminum 3D printing project consists of three stages constructing simple, moderate, and complex parts. During each stage, multiple printing trials will be run with sintering and data analyzation following. Data tables will be kept comparing different printing factors such as layer thickness and nozzle size to determine optimal printing settings. Sintering parameters will also be researched to find the most advantageous method of achieving desired properties of final parts. The physical properties of each part will be studied and collected before moving on to each stage of the process. These properties include hardness, conductivity, and surface finish along with the dimensions of each part to determine shrinkage between processes. The 3D printing of parts will take place in Foundation Hall and the sintering process will take place in the Lewis Hall metallography lab.

Abstract Summary: The purpose of crushing coke is to meet the size requirements for the specified cupola. When coke is heated, it generates enough heat to melt the iron. Given that coke crushed smaller than the specifications will create unnecessary hazardous airborne chemicals like carbon monoxide, there should be a standardized method of producing usable coke. According to the American Society for Testing Materials, the requirements for ash are less than or equal to 12%. The coke is fed into the cupola through the stack in layers of metal, flux, and coke. Once the process begins, the coke can be continuously provided, so the cycle time for producing the coke must be increased for desired output. Cast Iron is the output used to teach students in the MET department here at Tennessee Technological University.

Abstract Summary: The current market lacks an adjustable protective carry case. Our client desires to fulfill that need and has contracted us to build a working prototype. The task is to develop a cost-effective design that conforms to any item placed within the case. The prototype must be able to withstand numerous user-preformed-resets in addition to typical environmental stresses. We embarked on a rigorous design process as we shifted towards 3D printed elements rather than typical metal telescoping rods. The design will implement various types of foam for a range of protective characteristics.

Abstract Summary: Skyline Manufacturing (Nashville, TN) has 5 wire EDM machines that have buzzers that activate when the machine has a stoppage. The machines are all located within the same area of the facility and the nondescript buzzing sound has already caused confusion for the programmers using the machines. Our goal is to splice into the power source supplying the buzzer and install LED (Light Emitting Diode) status lights for each machine. Each LED will be routed to a receiver box located at the programmer's desk to allow the programmer to quickly assess and know which machine is stopped to improve overall efficiency.

Abstract Summary: To experimentally determine the extent to which incorporating corrugations in spiral ducts will increase their strength, thus permitting operating and collapse pressures that are higher than non-corrugated ducts of the same gauge. It is expected that this research will yield a table of negative pressure capacity for several standard gauge spiral ducts, with and without corrugations, that will enable the estimation of maximum deflection of the ducts. This will also provide guidance regarding potential collapse pressures. The test procedures reported herein conformed to the requirements of the SMACNA HVAC Duct Construction Standard Metal and Flexible (2020), except as noted (minor deviations from the test standard were required).
