The Analysis Of Ion Flow Between The Human Body And Local Ground, Paul T. Rioux

Honors Theses and Capstones

The project was designed to get a better sense of the phenomenon referred to as Earthing. Earthing is defined as the process where the human body is in contact with the earth and can freely transfer ions between the Earth and itself. Those promoting the idea of earthing say that this transfer of ions is important in maintaining a healthy immune system, and they claim that the recent increase in autoimmune diseases is the result of humans being insulated from the ground because of the shoes they wear and the places in which they live.

Estimating Connecticut Stream Temperatures Using Predictive Models, Erik Carlson

Honors Theses and Capstones

The Connecticut Department of Energy and Environmental Protection (CT DEEP) seeks to better classify their streams into thermal regimes (cold, cold transitional, warm transitional, and warm water). A prediction model was created based upon physical characteristics such that CT DEEP could classify streams into thermal regimes based upon the parameters described in Lyons et al. 2009 and compare them to their own classification system. Accurately classifying these thermal regimes determines the environmental protection provided to a stream as well as the potential for establishing fisheries.

Arched Bridges, Lily Beyer

Honors Theses and Capstones

An exploration of arched bridges through history. Influence lines for three-pinned and two-pinned arches for moment and axial load are developed. An analysis of the Chesterfield Brattleboro Bridge is included

Electrochemical Deposition Of Ag-Sn Nanoparticles For Photovoltaic Current Collection Efficiency, Rebecca Wilson

Honors Theses and Capstones

Photovoltaic cells utilize a semiconductor to harness the sun's energy, then conduct the energy by silver current collector lines to an energy storage device. To make photovoltaic cells less expensive and more energy efficient, silver-tin nanoparticles were researched to incorporate into the silver polymer paste that makes up current collector lines. The Ag-Sn alloy was synthesized by electrochemical deposition, and was then characterized by it's melting point and crystal structure.

Fish Cage Physical Scale Modeling, Michael J. Palczynski

Master's Theses and Capstones

Scale model tests were completed in the University of New Hampshire (UNH) Wave/Tow tank to determine the movements and forces on two different fish cage models. The results of the testing were used to validate a finite element analysis and also were scaled up to that of a full sized, deployed fish cage used for aquaculture purposes.

The first model was a “skeleton” cage (without nets) rectangular in shape. This model was moored submerged in front of a viewing window and subjected to various regular waves. The motions were then recorded nonintrusively by means of an optical system acting through …
