Study Of Feasability For Phase Difference Extraction Using Software Defined Radio In Location Analysis, Paul Miller
Study Of Feasability For Phase Difference Extraction Using Software Defined Radio In Location Analysis, Paul Miller
Masters Theses
Here is a method for using the phase of an HF radio signal for use in location analysis. This computation is implemented in a software defined radio processing block in the GNU Radio environment. The signals analyzed are received by an Ettus Research USRP SDR. We created a phase analysis system called WMU Rootsync, which compares the roots of a received signal to the roots of a generated reference signal for the phase analysis. This research describes a prototype method for phase analysis only. Future projects may use these ideas differently than presented here. We intend for future projects to …
An Embodied Perspective Of Expertise In Solving The Problem Of Making A Geologic Map, Caitlin Norah Callahan
An Embodied Perspective Of Expertise In Solving The Problem Of Making A Geologic Map, Caitlin Norah Callahan
Dissertations
The task of constructing a geologic map is a cognitively and physically demanding field-based problem. The map produced is understood to be an individual’s two-dimensional interpretation or mental model of the three-dimensional underlying geology. A popular view within the geoscience community is that teaching students how to make a geologic map is valuable for preparing them to deal with disparate and incomplete data sets, for helping them develop problem-solving skills, and for acquiring expertise in geology. Few previous studies have focused specifically on expertise in geologic mapping. Drawing from literature related to expertise, to problem solving, and to mental models, …
Ethical Ambivalence In Local Television Weathercasting: A Rossian Analysis, Vernon Keith Thompson
Ethical Ambivalence In Local Television Weathercasting: A Rossian Analysis, Vernon Keith Thompson
Masters Theses
Today’s television weathercasters are being called upon increasingly to go beyond benign weather prognostications to become the “newsroom experts” for science topics. The expectation to act as both scientists and journalists can cause ethical ambivalence (EA), a sociological condition in which, faced with conflicting norms, the subject feels that he/she is being pulled psychologically in two different directions (Jansen & Von Glinow, 1985). This thesis presents a Rossian analysis of climate change in weathercasting, a topic that captures the most important ethical tensions arising from conflicting duties within the weathercaster role, specifically: a) how might the duties of the television …
Creating Sustainable Economic And Ecological Growth In The Congo Basin: Bushmeat Consumption And Biodiversity Protection, Richelle Lynn Warnock
Creating Sustainable Economic And Ecological Growth In The Congo Basin: Bushmeat Consumption And Biodiversity Protection, Richelle Lynn Warnock
Masters Theses
This research examines the economic and ecological sustainability of bushmeat hunting in the Congo Basin, specifically the Democratic Republic of Congo and the Republic of Congo. Although bushmeat hunting has provided short term gain for individuals in the region, long term solutions focusing on micro and macro level interventions may provide community wide benefits, while protecting Congo Basin wildlife. Research shows that a focus on the development of key economic sectors such as agriculture, mineral resources and hydroelectricity, as well as the growth of infrastructure may provide viable economic gain for the Congo Basin. Ecotourism and improvements to forest management …
