C2 Domain Ontology Within Our Lifetime, Leslie Winters, Andreas Tolk
C2 Domain Ontology Within Our Lifetime, Leslie Winters, Andreas Tolk
Computational Modeling & Simulation Engineering Faculty Publications
Agile Command and Control (C2) requires agile information sharing with an increasingly wide variety of military and non-military partners. While current net-centric approaches may improve information sharing within a particular niche of C2, they do not support information sharing across the larger C2 domain. Although not a silver bullet, the development and application of a C2 domain ontology to improve C2 data and service integration appears to be increasingly realistic. In fact, there are several examples of successful ontology applications in domains such as medicine, biology, and engineering, and the new discipline of Applied Ontology is emerging. C2 data, architecture, …

Rfid Tags / Planar Inductors As Chemical Sensor Platforms In Liquid Sensing Applications, Gregory Donald Schumacher-Novak
Master's Theses (2009 -)
In this work, RFID tags are investigated as a liquid-phase chemical sensing platform. A dual-layer of selective coating film with polyaniline (PANi) on top of poly(epichlorohydrin) (PECH) is used for the detection of trace amounts of organic compounds (toluene and ethylbenzene) in aqueous solutions. Various experiments were performed to evaluate the coated RFID tag sensors. Shifts in the impedance and resonant frequency due to analyte sorption are measured. Details of the responses of the dual-layer film to different pH baseline solutions are shown. The results show that this dual-layer film can be used to detect toluene and ethylbenzene with high …
A Study Of Central Florida Nonroad Voc And Nos Emissions And Potential Actions To Reduce Emissions, Michael Radford
A Study Of Central Florida Nonroad Voc And Nos Emissions And Potential Actions To Reduce Emissions, Michael Radford
Electronic Theses and Dissertations
Ground-level ozone is harmful to the human respiratory system, as well as the environment. The national EPA 8-hour ozone standard for ground-level ozone was reduced from 85 parts per billion (ppb) to 75 ppb in 2008, and trends from previous years show that some of the counties in Central Florida could be in danger of violation. Violation means "non attainment" status; in which the county is ordered by EPA to develop specific implementation plans to reduce its emissions. The objective of this study was to compile an emissions inventory of volatile organic compounds (VOCs) and nitrogen oxides (NOx) from nonroad …

Reconfigurable End Effector Allowing For In-Hand Manipulation Without Finger Gaiting Or Regrasping, Jacob Ames Ziesmer
Master's Theses (2009 -)
The goal of this thesis is to move a step towards the solution of the bin picking problem. A novel metamorphic end effector is proposed, tested for proof of concept and analyzed using standard techniques of degrees of freedom and graph theory as well as a classical dynamic analysis. Once proof of concept was achieved, the results from the analysis were formed into an optimization program with the hope of finding a more stable, predictable mechanism.

2008 Fall Engr333 Project Final Report, 2008 Fall Engr333
ENGR 333
The Calvin College Engineering 333 class of 2008 was challenged with the question, “What would it take to implement an energy efficiency fund at Calvin?” Before addressing this question, another had to be asked: “What is an energy efficiency fund?” An energy efficiency fund is a revolving fund which takes seed money from donations, tuition, or grants and invests it into projects that save energy. Energy cost savings from the projects are routed back to the fund to help it grow and enable it to finance future projects. In order to begin this, the senior engineering students began organizing and …

The Arctic seafloor remains one of the last unexplored areas on Earth. Exploration of this unique environment using standard remotely operated oceanographic tools has been obstructed by the dense Arctic ice cover. In the summer of 2007 the Arctic Gakkel Vents Expedition (AGAVE) was conducted with the express intention of understanding aspects of the marine biology, chemistry and geology associated with hydrothermal venting on the section of the mid-ocean ridge known as the Gakkel Ridge. Unlike previous research expeditions to the Arctic the focus was on high resolution imaging and sampling of the deep seafloor. To accomplish our goals we …

New Freedom: An Investigation Into The World Of Prosthetics, Jenna Marcus
Senior Honors Projects
Prosthetics dates back thousands of years, with some of the earliest recorded devices dating back to the ancient Egyptians. The devices are used to replace a limb that may have been lost due to a variety of reasons. Of course, much has changed since the basic wooden devices. What is exceptionally fascinating about prosthetics and orthotics is that the field is always changing and become more advanced; it truly has infinite potential. Prosthetics has evolved over many centuries to be what it is today, but where will the technology go in the future?
Focusing on one area of prosthetics, specifically …
