Evaluating Alternatives For Drinking Water At Deployed Locations, Brian S. Hughes
Evaluating Alternatives For Drinking Water At Deployed Locations, Brian S. Hughes
Theses and Dissertations
Because of potential improvements to water security and cost savings, military decision makers may want to consider new means of providing potable water to Airmen in deployed locations. Drilling for water and field bottling show great potential because of the increased security and lower per unit cost when compared to bottled water from approved sources. However, the selection of the best means to supply water is a hard decision which must balance multiple objectives (e.g., security, palatability, and convenience) against limited resources (e.g., cost, airlift, trucks, and personnel). A multi-objective decision analysis model quantifies a decision-maker's values regarding the many …

Soil Stable Carbon Isoptope Analysis Of Landscape Features At Aguateca, Guatemala, David R. Wright
Soil Stable Carbon Isoptope Analysis Of Landscape Features At Aguateca, Guatemala, David R. Wright
Theses and Dissertations
The ancient Maya of the Classic period (1700-1050 B.P.) relied on maize agriculture to support their populations. The agricultural systems they employed to produce that maize varied in form and degree of intensity, with more productive forms of agriculture needed in the Late Classic period (1350-1050 B.P.) to sustain the peaking population. It is likely that the ancient systems of production agriculture contributed to environmental degradation that in turn contributed to the pressures that culminated in the collapse of the civilization. In this study, stable carbon isotope ratios contained in the soil organic matter were used to further investigate ancient …

The Dogma Of The 30 Meter Riparian Buffer: The Case Of The Boreal Toad (Bufo Boreas Boreas), Michael C. Goates
The Dogma Of The 30 Meter Riparian Buffer: The Case Of The Boreal Toad (Bufo Boreas Boreas), Michael C. Goates
Theses and Dissertations
We tested the adequacy of standard 30 m riparian buffers for semi-aquatic vertebrate species, using the boreal toad (Bufo boreas boreas) as an example. We monitored toad populations in south-central Utah using radio telemetry during the summers of 2003 and 2004. We found 30 m buffers inadequate for protecting boreal toads and suggest this is likely true for other species as well. Managers must consider several factors when constructing buffers: (1) Buffer requirements may vary by time of year. While we located toads most often in wet habitats, toads commonly utilized upland habitats in late summer, occasionally at distances greater …

An Exploration Of The Effects Of Genetic Drift On The Endangered Red-Cockaded Woodpecker, Ryan E. Nelson
An Exploration Of The Effects Of Genetic Drift On The Endangered Red-Cockaded Woodpecker, Ryan E. Nelson
Theses and Dissertations
The Red-cockaded Woodpecker (RCW) (Picoides borealis) is classified as an endangered species under the Endangered Species Act of 1973 due to habitat fragmentation and prescribed burn suppression. Given the endangerment of the RCW, the genetic variation of the small populations will decrease over time due to random genetic drift. The only method of battling the negative effects of random genetic drift is to move, or translocate, genetically diverse birds into the fragmented populations thereby increasing the genetic diversity of the small populations. The objective of this research effort was to explore the effects of random genetic drift on small RCW …

Consequently, the Air Force seeks a reusable military launch vehicle that can be launched inexpensively and quickly regenerated between flights. Air Force Research Laboratory personnel desire a tool to help evaluate candidate designs and perform tradeoff studies necessary to acquire a launch vehicle that will achieve Air Force goals. The objective of this research was first to develop a conceptual model of maintenance operations needed to regenerate a …
A Monocular Vision Based Approach To Flocking, Brian Kirchner
A Monocular Vision Based Approach To Flocking, Brian Kirchner
Theses and Dissertations
Flocking is seen in nature as a means for self protection, more efficient foraging, and other search behaviors. Although much research has been done regarding the application of this principle to autonomous vehicles, the majority of the research has relied on GPS information, broadcast communication, an omniscient central controller, or some other form of "global" knowledge. This approach, while effective, has serious drawbacks, especially regarding stealth, reliability, and biological grounding. This research effort uses three Pioneer P2-AT8 robots to achieve flocking behavior without the use of global knowledge. The sensory inputs are limited to two cameras, offset such that the …
Performance Analysis Of A Cooperative Search Algorithm For Multiple Unmanned Aerial Vehicles Under Limited Communication Conditions, Kevin M. Morris
Performance Analysis Of A Cooperative Search Algorithm For Multiple Unmanned Aerial Vehicles Under Limited Communication Conditions, Kevin M. Morris
Theses and Dissertations
This research investigates the impacts of realistic wireless communications upon a group of unmanned aerial vehicles (UAVs) utilizing a distributed search algorithm. The UAVs are used to survey an area for mobile targets and they require communication to cooperatively locate the targets. The mobile targets do not continually radiate energy, which exacerbates the search effort; a UAV could fly directly over a target and not detect it. A simulation of cooperative UAVs is implemented using the OPNET Modeler network simulation tool. The search performance of a group of UAVs is observed when communication range, data rate, and the number of …

The Simulation Of Off-Axis Laser Propagation Using Heleeos, Scott L. Belton
The Simulation Of Off-Axis Laser Propagation Using Heleeos, Scott L. Belton
Theses and Dissertations
Emerging technology high energy laser (HEL) weapon systems create a myriad of new threats to safety as well as security. One of the primary causes of these concerns is off-axis laser propagation caused by ever-present particulate and molecular scattering medium in the atmosphere. The scatter from these aerosols and molecules can redirect some of the HEL's concentrated energy towards unintended targets such as the eyes of pilots, friendly fighters on the surface, or innocent bystanders. Of particular interest to the laser intelligence (LASINT) community is the possibility that off-axis irradiance from HEL weapon systems could be covertly measured with enough …

Analysis Of Bacterial Population And Distribution In The Developing Strata Of A Constructed Wetland Used For Chlorinated Ethene Bioremediation, Milton J. Clausen Jr.
Theses and Dissertations
Chlorinated hydrocarbons and their degradation products are among of the most common organic groundwater contaminates in the United States. These compounds attack the central nervous system in animals and can affect the photosynthesis of plants. These compounds are also resistant to degradation in the environment and, because of this, pose a risk to any ecosystem in which they are present. This study identified the dominant microbial species in a constructed treatment wetland at Wright-Patterson AFB, Dayton, Ohio using 16S rRNA gene sequence analysis. Samples were taken from three different depths and during each of the four seasons. These samples were …
Exploiting Semi-Directional Transceivers For Localization In Communication Systems, Andrew S. Crockford
Exploiting Semi-Directional Transceivers For Localization In Communication Systems, Andrew S. Crockford
Theses and Dissertations
Localization is the process of determining relative, as well as absolute, positions of communicating devices. Traditionally, the process is conducted using range or directional estimates. In contrast, this research uses weak information to form relatively tight bounds on possible locations of communicating devices. Under certain conditions, achieved location estimation results are strong. However, these results are highly sensitive to the operating conditions of the proposed networks. More significant results were obtained from specialized cases and that the application yields somewhat limited information for a general randomized network topology. Feasible localization results were found to be attainable but not necessarily practical …
Doppler-Only Multistatic Radar, Dustin G. Mixon
Doppler-Only Multistatic Radar, Dustin G. Mixon
Theses and Dissertations
In order to estimate the position and velocity of a target, most multistatic radar systems require multiple independent target measurements, such as angle-of-arrival, time-of-arrival, and Doppler information. Though inexpensive and reliable, Doppler-only systems have not been widely implemented due to the inherent nonlinear problem of determining a target’s position and velocity from their measurements. We solve this problem. In particular, we first establish the lack of observability in the Doppler-only bistatic system, thereby demonstrating the need for multiple transmitters and/or receivers. Next, for a multistatic system with a sufficient number of transmitter-receiver pairs, we invoke classical optimization techniques, such as …
