Given multi-model ensemble climate projections, the goal is to accurately and reliably predict future sea-level rise while lowering the uncertainty. This problem is important because sea-level rise affects millions of people in coastal communities and beyond due to climate change's impacts on polar ice sheets and the ocean. This problem is challenging due to spatial variability and unknowns such as possible tipping points (e.g., collapse of Greenland or West Antarctic ice-shelf), climate feedback loops (e.g., clouds, permafrost thawing), future policy decisions, and human actions. Most existing climate modeling approaches use the same set of weights globally, during either regression or …

Wind-Powered Continuous Reverse Osmosis Water Desalination, Aliah Adriana Binti Khairul Hisham
Discovery Undergraduate Interdisciplinary Research Internship
Water scarcity is a grave issue that is faced by lots of people worldwide. This phenomenon is further exacerbated by climate change, overpopulation, and water-intense industrial activities. To combat this issue, reverse osmosis (RO) water desalination system is broadly introduced in order to produce freshwater while maintaining the desired thermodynamic efficiency and economic feasibility. RO water desalination is a process of separating freshwater from salt water using a semi-permeable membrane. In status quo, there are various forms of energy present in RO system (e.g: hydraulic, mechanical, electrical energy, etc.) to power the hydraulic components. The conversion from one form of …

Laboratory Characterization Of Unsteady Boundary Layers, Umair Sarwar, Cary Troy
The Summer Undergraduate Research Fellowship (SURF) Symposium
The study of waves and their effects on mean flow and turbulence in natural water bodies is an important issue for applications in aquatic biology, coastal engineering, sediment transport and hydrodynamic of the lake. These waves result in the generation of an oscillatory (Stokes) boundary layer near the bottom of the water column. The goal of this study was to conduct various experiments that will be used to characterize the turbulence in unsteady boundary layers and help understand the relation between various flow variables (e.g. wave amplitude, frequency, water depth, turbulent kinetic energy, etc.). Using the research facilities provided, three …

Bio-Inspired Robotic Fish With Vision Based Target Tracking, Eric Anderson
Open Access Theses
The lionfish is an invasive species that out-competes and overcrowds native sh species along the eastern seaboard of the United States and down into the Caribbean. Lionfish populations are growing rapidly. Current methods of monitoring lionfish populations are costly and time intensive. A bio-inspired robotic fish was built to use as an autonomous lionfish tracking platform. Lionfish are tracked visually using an onboard processor. Five different computer vision methods for identification and tracking are proposed and discussed. These include: background subtraction, color tracking, mixture of Gaussian background subtraction, speeded up robust feature (SURF), and CamShift based tracking. Each of these …
