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 …

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 …
