Integration Of Lidar And Imagery To Delineated Water Bodies For Change Detection, 2016 Murray State University
Integration Of Lidar And Imagery To Delineated Water Bodies For Change Detection, Ashley E. Casselberry, Cetin Haluk
Through integration of Light Detection and Ranging (LiDAR) data and high spatial imagery, it is plausible to delineate the bodies of water in order to monitor their changes in size. The purpose of this study is to integrate two different sets of LiDAR data, several multi-date high spatial resolution National Agriculture Imagery Program (NAIP) images, and multi-dateLandsat-8 satellite images of Ballard County, Kentucky for the delineation of the water bodies in the County. Accuracy and precision of the datasets in terms of spatial and spectral resolutions will be examined. The hypothesis is that an integration of such datasets would provide ...
Vegetation Mapping Of Mammoth Cave National Park Using Multi-Date Landsat-8 Imagery And Lidar Data, Hongli Yang, Robin Q. Zhang
Up-to-date and detailed vegetation map provides critical information for habitat management. In addition, a vegetation map is necessary for the Park’s Fire Management, for classification of fuel types, and for delineation of fire management units. There have been several attempts of vegetation mapping in 1934, 1975 and 1997. Recent advancements in mapping technology and the availability of high resolution Lidar data call for a new vegetation map for the Park’s management team.
In this study, Landsat-8 Operational Land Imager (OLI) imagery, Lidar and geology dataset were applied to vegetation mapping. Habitat types are determined by a combination of ...
Generalized Least-Powers Regressions I: Bivariate Regressions, 2016 CUNY Kingsborough Community College
Generalized Least-Powers Regressions I: Bivariate Regressions, Nataniel Greene
Publications and Research
The bivariate theory of generalized least-squares is extended here to least-powers. The bivariate generalized least-powers problem of order p seeks a line which minimizes the average generalized mean of the absolute pth power deviations between the data and the line. Least-squares regressions utilize second order moments of the data to construct the regression line whereas least-powers regressions use moments of order p to construct the line. The focus is on even values of p, since this case admits analytic solution methods for the regression coefficients. A numerical example shows generalized least-powers methods performing comparably to generalized least-squares methods, but ...
Newsvendor Models With Monte Carlo Sampling, 2016 East Tennessee State University
Newsvendor Models With Monte Carlo Sampling, Ijeoma W. Ekwegh
Electronic Theses and Dissertations
Newsvendor Models with Monte Carlo Sampling by Ijeoma Winifred Ekwegh The newsvendor model is used in solving inventory problems in which demand is random. In this thesis, we will focus on a method of using Monte Carlo sampling to estimate the order quantity that will either maximizes revenue or minimizes cost given that demand is uncertain. Given data, the Monte Carlo approach will be used in sampling data over scenarios and also estimating the probability density function. A bootstrapping process yields an empirical distribution for the order quantity that will maximize the expected proﬁt. Finally, this method will be used ...
Reducing Pollen Dispersal Using Forest Windbreaks, 2016 University of Connecticut - Storrs
Reducing Pollen Dispersal Using Forest Windbreaks, Carol Auer, Thomas Meyer, Vernie Sagun
Plant Science Articles
The adoption of genetically engineered (GE) crops has created a demand for practical methods to mitigate pollen dispersal and gene flow. The goal of this project was to measure the ability of a narrow forest windbreak to reduce downwind pollen fluxes from switchgrass (Panicum virgatum L.), a North American grass and model biofuels feedstock. Switchgrass fields were established in two identical plots where one had a forest windbreak and the other was in an open (control) site. Switchgrass reproduction, pollen dispersal, wind speed, and wind direction were measured over two years. Daily release of switchgrass pollen peaked at 11:00-13 ...
Comparison Of Combustion Efficiency To In-Situ Atmospheric Ammonia Measurements From A Miniature Chemical Ionization Mass Spectrometer In The La Basin, Taylor Krause, Barry L. Lefer, Timothy H. Betram, Steven R. Schill
Student Research Day Abstracts and Posters
Atmospheric ammonia (NH3) has been shown to impact the environment and threaten both human and animal health, especially in heavily populated urban areas, yet to date there remains a paucity of direct measurements. Recent studies have suggested that ammonia may be generated as a byproduct of fossil fuel emissions due to highly active catalytic converters in light-duty gasoline vehicles. To investigate this relationship, an airborne miniature Chemical Ionization Mass Spectrometer (miniCIMS) was used to directly measure atmospheric ammonia and combustion reaction products in the Southern California LA Basin, during the 2015 NASA Student Airborne Research Program (SARP). The temporal ...

Forensic Chemical Analysis Of Synthetic Cathinones Using Portable Mass Spectrometric Instrumentation, 2016 Virginia Commonwealth University
Forensic Chemical Analysis Of Synthetic Cathinones Using Portable Mass Spectrometric Instrumentation, Caitlin N. Cain
Undergraduate Research Posters
Forensic laboratories face issues with large backlogs on evidence needing to be analyzed is due to two reasons: budgeting issues and the emergence of designer drugs. Currently, forensic laboratory directors cite that there are a shortage of scientists to deal with the yearly increase in caseloads. Additionally, designer drugs like synthetic cathinones, commonly known as “bath salts,” have increased the backlog due to the changing chemical compositions and misidentification as other compounds. Therefore, the use of a portable mass spectrometer for on-site forensic chemical analysis of synthetic cathinones would reduce the backlog of suspected controlled substances in forensic chemistry laboratories ...

Perspectives For Low-Carbon Electricity Production Until 2030: Lessons Learned From The Comparison Of Local Contexts In Poland And Portugal, Wojciech Budzianowski, Joao Gomes
This paper compares perspectives for low-carbon electricity production in two EU member states - Poland and Portugal until 2030. Electricity production capacities, carbon emissions of electricity production, and production cost of electricity (COE) of Poland and Portugal are analyzed. The dilemmas of investments into low-carbon electricity production technologies relying on: (i) renewable energy sources (RES), (ii) nuclear fuel, and (iii) fossil fuels integrated with carbon capture and sequestration (CCS) are discussed. Roadmap 2050 recommends about 40% decarbonization of electricity generation by 2030 and 100% by 2050. Based on electricity production mix forecast for 2030 carbon emissions of electricity are estimated at ...

The Cost Of Karst Subsidence And Sinkhole Collapse In The United States Compared With Other Natural Hazards, David J. Weary
Sinkhole Conference 2015
Rocks with potential for karst formation are found in all 50 states. Damage due to karst subsidence and sinkhole collapse is a natural hazard of national scope. Repair of damage to buildings, highways, and other infrastructure represents a significant national cost. Sparse and incomplete data show that the average cost of karst-related damages in the United States over the last 15 years is estimated to be at least $300,000,000 per year and the actual total is probably much higher. This estimate is lower than the estimated annual costs for other natural hazards; flooding, hurricanes and cyclonic storms, tornadoes ...
Geometric Constructions From An Algebraic Perspective, 2015 California State University-San Bernardino
Geometric Constructions From An Algebraic Perspective, Betzabe Bojorquez
Electronic Theses, Projects, and Dissertations
Many topics that mathematicians study at times seem so unrelated such as Geometry and Abstract Algebra. These two branches of math would seem unrelated at first glance. I will try to bridge Geometry and Abstract Algebra just a bit with the following topics. We can be sure that after we construct our basic parallel and perpendicular lines, bisected angles, regular polygons, and other basic geometric figures, we are actually constructing what in geometry is simply stated and accepted, because it will be proven using abstract algebra. Also we will look at many classic problems in Geometry that are not possible ...
External Field Energy Problems On The Sphere And Minimal Energy Points Separation, 2015 Indiana University - Purdue University Fort Wayne
External Field Energy Problems On The Sphere And Minimal Energy Points Separation, Peter D. Dragnev, Peter Boyvalenkov, Douglas P. Hardin, Edward Saff, Maya Stoyanova
Mathematical Sciences Faculty Presentations
Minimal energy problems in the presence of external fields are a classic topic in logarithmic potential theory in the complex plane. Applications vary from asymptotics of orthogonal polynomials, to fast decreasing polynomials, to weighted polynomial and rational approximation, etc. Here we shall introduce the counterpart for measures supported on the unit sphere, with motivation arising from an application to separation results for minimal Riesz s-energy spherical configurations. A natural extension to axis-symmetric external fields is presented and separation results for minimal energy points with external fields. Finally, a work in progress report considers the special case s=d-2, where the ...
