(2013-04-19)
Attacks on information networks have been increasing in frequency and success in recent years. Attack methods are becoming increasingly sophisticated, and network defense systems have not kept pace. IDS and IPS systems ...
Spacecraft Relative Motion Applications to Pursuit-Evasion Games and Control Using Angles-Only Navigation
(2015-05-29)
In the first part, applied linear quadratic (LQ) differential game theory to derive linear control laws for orbit pursuit-evasion (PE) problem and extended LQ game theory to nonlinear PE game using the state-dependent ...
Spatial Analysis of Air Velocity, Air Temperature, and Humidity in Natureform Single-Stage Incubators Using Simulated Eggs
(2023-08-01)
Spatial variation of the thermal environment within incubators has been a critical concern for the optimal development of egg embryos. Variations in air velocity, temperature, and humidity can alter embryonic mortality, ...
Spatial Analysis of Plateau Pika Habitat Use
(2017-07-27)
The habitat occupied by animals during their normal activities is referred to as their home
range. This physical space contains limited resources that are necessary for reproduction and
survival. Using spatial analysis ...
Spatial and temporal investigation of taste and odor-producing microorganisms in Lake Saugahatchee
(2021-07-20)
Geosmin is one of the most prevalent taste and odor compounds found in drinking water and is produced by a variety of algae. Quantitative PCR (qPCR) can be used to identify and monitor the growth of geosmin producers by ...
Spatial and Temporal Trends and the Role of Land Use/Cover on Water Quality and Hydrology in the Fish River Watershed
(2010-12-17)
This study focuses on exploring linkages between land use/cover (LULC) and water quality/quantity at both spatial and temporal scales in the Fish River watershed. The Fish River, in coastal Alabama, is of critical importance ...
A Spatial Approach to Analyzing the Effects of Weather Patterns on Honey Bee (Apis mellifera) Colony Loss Across the United States
(2022-04-18)
Western honey bees (Apis mellifera) have experienced high rates of colony loss over the
past decade. Honey bees are critical to agricultural production, providing 15 billion to the United
States (U.S.) economy each ...
Spatial Distribution and Mass Transport of Per- and Polyfluoroalkyl Substances (PFAS) in Surface Water Systems
(2022-12-05)
Per- and polyfluoroalkyl substances (PFAS) are a group of nearly 5,000 anthropogenic organic substances produced since the late 1940s. These substances have been used in various consumer products and industrial applications ...
Spatial Ecology of Male White-Tailed Deer in the Crosstimbers and Prairies Ecoregion
(2008-08-15)
We examined daily movement paths of radio-collared male white-tailed deer (Odocoileus virginianus) during the breeding season (Oct. 1st- Dec. 15th), from 1995-1997, at the McAlester Army Ammunition Plant (McAAP) in ...
Spatial ecology of the eastern diamond-backed rattlesnake (Crotalus adamanteus)
(2007-08-15)
An animal’s spatial ecology may be governed by variables operating at more than one spatial scale, which underscores the importance of incorporating multiple spatial scales into habitat selection models. This is particularly ...
A Spatial Econometric Analysis of the Effects of Subsidized Housing and Urban Sprawl on Property Values
(2011-05-04)
Property owners often resist the idea of siting public or subsidized housing in their neighborhood. The notion that subsidized housing exerts a negative externality effect on adjacent properties has been investigated ...
Spatial Intelligence - Route Prediction and Planning Base on Geospatial Information
(2022-05-10)
With the advances in localization techniques and popularity of mobile devices, Spatial Intelligence penetrated people's lives. What is Spatial Intelligence? It is 1) able to provide “smart” and intelligent services to ...
Spatial Relationships of Suspended Solids and Phosphorus in Bioretention Cells
(2017-11-17)
Bioretention cells (BRCs) are a stormwater practice designed to infiltrate, store, and treat stormwater. These cells help to mitigate stormwater flow volume, flow rate, and remove nutrients. Suspended sediments that are ...
Spatial Spread and Front Propagation Dynamics of Nonlocal Monostable Equations in Periodic Habitats
(2011-07-25)
This dissertation is concerned with spatial spread and front propagation dynamics of
monostable equations with nonlocal dispersal in spatially periodic habitats. Such equations
arise in modeling the population dynamics ...
Spatial Spread Dynamics of Monostable Equations in Spatially Locally Inhomogeneous Media with Temporal Periodicity
(2013-05-31)
This dissertation is devoted to the study of semilinear dispersal evolution equations.
These type of equations are called as Monostable or KPP type equations, which arise
in modeling the population dynamics of many ...
Spatial-Temporal Analysis of Heavy Metal Water Pollution and the Impact on Public Health in China
(2015-05-18)
Water is the source of life. China’s water pollution has become a burning research field because of the severely polluted conditions. 60 percent of the country's rivers were not potable according to the State Environmental ...
