Terrain Constrained Stereo Correspondence, Gabrielle Inglis, Chris Roman
Graduate School of Oceanography Faculty Publications
There is a persistent need in the oceanographic community for accurate three dimensional reconstructions of seafloor structures. To meet this need underwater mapping techniques have expanded to include the use of stereo vision and high frequency multibeam sonar for mapping scenes 10's to 100's of square meters in size. Both techniques have relative advantages and disadvantages that depend on the task at hand and the desired accuracy. In this paper, we develop a method to constrain the often problematic stereo correspondence search to small sections of the image that correspond to estimated ranges along the epipolar lines calculated from coregistered …
Development Of A New Lagrangian Float For Studying Coastal Marine Ecosystems, Alex Schwithal, Chris Roman
Development Of A New Lagrangian Float For Studying Coastal Marine Ecosystems, Alex Schwithal, Chris Roman
Graduate School of Oceanography Faculty Publications
This paper presents an overview and initial testing results for a shallow water Lagrangian float designed to operate in coastal settings. The presented effort addresses the two main characteristics of the shallow coastal environment that preclude the direct of use of many successfully deep water floats, namely the higher variation of water densities near the coast compared with the open ocean and the highly varied bathymetry. Our idea is to develop a high capacity dynamic auto-ballasting system that is able to compensate for the expected seawater density variation over a broad range of water temperatures and salinities while using measurements …
Powering The Future: The Fabrication Of A Novel Passive Micro Direct Ethanol Fuel Cell, Zachary Chin
Powering The Future: The Fabrication Of A Novel Passive Micro Direct Ethanol Fuel Cell, Zachary Chin
Senior Honors Projects
The scope of this research includes principles of operation, areas of enhancement, and the fabrication processes of micro direct ethanol fuel cells. This research spreads light on the technology of fuel cells, offers methods to aide the performance of the direct ethanol fuel cell, and provides the method to produce an enhanced micro direct ethanol fuel cell power supply. The proposed micro direct ethanol fuel cell provides power independent of its orientation and without external fluid pumps. In satisfying these details the fuel cell system is entirely sealed within a small package fabricated using rapid prototyping technology and operates solely …

Assessing The Feasibility Of Wind Power Production For The University Of Rhode Island’S Bay Campus, Kenneth A. Critz
Senior Honors Projects
Governor Carcieri and the Rhode Island Office of Energy Resources (OER) set a goal for Rhode Island to be powered by 15% renewable energy resources. It was determined that wind power was the only utility scale means of renewable energy production abundant enough to satisfy this initiative. In January of 2006 the RI WINDS program was established and Applied Technology Management (ATM) was contracted to perform a preliminary assessment of potential areas, including RI coastal waters, where wind power could be developed. This assessment indicated that “there are significant wind resources in the State of Rhode Island both onshore and …
