An Engineering Design-Oriented First Year Biomedical Engineering Curriculum, Simon Jones

Faculty Publications - Mechanical Engineering

This Technical Report aims to explain how to apply the discreteWavelet Balance Method (dWBM) for solving periodic differential equations using periodized Daubechies wavelets. The primary goal is to provide the user sufficient details to implement the technique without extensive mathematical background. Chapter 2 of this document reviews the discrete Fourier transform using a multivariate regression approach, followed by a review of the discrete Harmonic Balance Method (dHBM) for approximating solutions to periodic differential equations. It is important the reader complete this chapter, even if they are familiar with the topics, since the approaches demonstrated in Chapter 2 with harmonic functions …

Investigating The Removal Of Stormwater Pollutants In Small-Scale, Constructed Treatment Wetlands, Katlyn Edwards

Rose-Hulman Summer Undergraduate Research Fellowships

Eutrophication of US surface waters is a growing problem due to nitrogen and phosphorus runoff in stormwater. In natural ecosystems, wetlands can absorb and remove a variety of water pollutants, including nutrients. Wetlands also provide flood control and wildlife habitat. Mimicking natural systems, constructed treatment wetlands can remove stormwater pollutants, are economic to build and maintain, provide a bionetwork for a wide range of plants and animals, and can be used for educational purposes.

While constructed treatment wetlands can remove stormwater pollutants such as total suspended solids, organic carbon, and nitrates, a significant reduction in phosphate concentrations has not been …

Comparison Between Two Group Signature Schemes, Hao Yang

Rose-Hulman Undergraduate Research Publications

Zerocoin is a cryptographic extension to Bitcoin. During its development, the developers decided to make use of group signature schemes to store and verify the coins. In order to compare the performance of Simple Authentication Scheme and the Dynamic Signature Scheme and figure out which one is the optimal choice for the Zerocoin scheme, I implemented them in Java and analyzed them theoretically. This paper will discuss the performance difference between two schemes, the Java implementation of them and the analysis.

Development Of A Foot Interface To Control Supernumerary Robotics Limbs, Emma Morris

Rose-Hulman Summer Undergraduate Research Fellowships

Supernumerary robotic limbs (SRLs) can be used to provide a person with extra arms to help with difficult tasks. For example, a task that normally requires three hands to complete could be accomplished by just one person with an SRL. One way to control an SRL and still leave both hands available is to use the foot. This paper describes two parts of developing this foot interface: characterizing the range of forces that the foot can apply, and prototyping systems for different control methods. First, a small sample of data was collected to learn how much force the foot can …

Discrete-Position Solar Tracking For Photovoltaic System, Shengnan Hong, Zheng Fu, Richard E. Stamper

Rose-Hulman Undergraduate Research Publications

The purpose of this research is to design a new tracking system for solar panels using the idea of discrete-position tracking. Compared with the traditional fixed solar panel, discrete-position trackers have a higher gain of harvesting solar radiation with smaller misalignment angles. Also, since we are trying to design the a passive tracker with solely mechanical structure to do the kinetics, a discrete-position tracker can decrease the cost of the maintenance to a huge extent in contrast to both one-axis and two-axis continuous tracking systems. The majority of the cost of maintaining a continuous tracker is the motor or hydraulic …

Analyzing A Small-Scale, Constructed Wetland For Stormwater Treatment, Juliann Apple, Pascal Schlee

Rose-Hulman Undergraduate Research Publications

Stormwater treatment by means of constructed wetlands has the ability to effectively remove pollutants such as total suspended solids, nitrite, nitrate, and ammonia. Utilizing two small, lab-scale constructed wetlands, one free water flow system and one subsurface flow system, our research team analyzed the levels of these pollutants at different locations in the wetland. Our team of two Civil and Environmental Engineering undergraduate students tested a variety of different water samples including tap water, stormwater, and a high nitrate solution. A consistent decrease in nitrate and nitrite was observed throughout the systems. While there was not an overall decrease in …

Predicting The Dynamic Binding Capacities For Adsorbents Using Bsa As A Model Protein, Gaoshan Li

Rose-Hulman Undergraduate Research Publications

Membrane adsorbers are one alternative to traditional bead-based chromatography that receive attention in the bioseparation process because of their ability to process material with lower residence times. However some properties of membranes make membrane adsorbers unrealistic for some applications. For example, some membrane adsorbers exhibit lower binding capacities compared with the traditional bead-based chromatography counterparts. The dynamic binding capacity (DBC) in this study is defined as the amount of protein bound in the column when the outlet reaches a certain concentration, which is 10% [2], and the equilibrium binding capacity (EBC) is the binding capacity under the equilibrium conditions, when …

Optimizing The Removal Of Stormwater Pollutants In Small-Scale, Constructed Treatment Wetlands, Isabella Evans

Rose-Hulman Undergraduate Research Publications

Natural wetlands use plants to absorb and break down harmful pathogens and water pollutants. This process improves water quality in a natural and efficient way. By mimicking natural wetlands with constructed wetlands, we are able to perform the same functions. We used the two small-scale treatment wetlands in the Cook Laboratory for Bioscience Research to perform experiments to optimize the removal of stormwater pollutants. These two treatment wetlands consist of three connected basins each with the goal of removing harmful pollutants in each basin. These stormwater pollutants include total suspended solids, biochemical oxygen demand (organic carbon), and nitrate. Past studies …
