Advances in ground penetrating radar imaging with multi-channel systems have greatly improved the speed and areal coverage of the ground. Along with improved imaging software, datasets recorded with multi-channel systems can be processed at similar speeds to coarsely spaced single channel data that would normally require additional time for interpolation processes to fill in the gaps between li...

In this paper, we describe the Geometric Path Planner (GPP) that produces routes for unmanned ground and air vehicles. The GPP generates plans that minimize a weighted, multi-metric cost function considering factors such as mobility risk, traversal time, sensor coverage, and stealth. In addition to cost minimization, the GPP is able to reason about hard constraints imposed on one or more of the...

During the past decade bark beetle (Ips typographus) attacks killed nearly all of the Norway spruce [Picea abies (L.) Karst.] stands in the unmanaged zone in the highlands of the Bavarian Forest National Park. This study was conducted to predict if and how long the catastrophic event might cause elevated nitrate NO3(-) concentration in seepage water, and if the presence of ground vegetation may...

In spatial analyses of causes or health effects of environmental pollutants, small units of analyses are usually preferred for internal environmental homogeneity reasons but can only be done when fine resolution data are available for most units. Objectives of this study were to determine which land use practices were spatially associated with ground water nitrate concentrations across Prince E...

Future Unmanned Aircraft Systems (UASs) are expected to be nearly autonomous and composed of heterogeneous Unmanned Aerial Vehicles (UAVs). While most of the current research focuses on UAV avionics and control algorithms, ground task automation has come to the attention of researchers during the past few years. Ground task automation not only relieves This paper is largely reprinted from the p...

This study proposes an approach that identifies and corrects for the vertical profile of reflectivity (VPR) by using Tropical Rainfall MeasuringMission (TRMM) precipitation radar (PR) measurements in the region of Arizona and southern California, where the ground-based Next Generation Weather Radar (NEXRAD) finds difficulties in making reliable estimations of surface precipitation amounts becau...

We present two novel contributions to the problem of region classification in scenery/landscape images. The first is a model that incorporates local cues with global layout cues, following the statistical characteristics recently suggested in [1]. The observation that background regions in scenery images tend to horizontally span the image allows us to represent the contextual dependencies betw...

Buildings in hot climate areas are responsible for high energy consumption due to cooling load requirements which lead greenhouse gas emissions. In order curtail the stress on national grid and reduce atmospheric emissions, it is of prime importance that buildings produce their own onsite electrical using renewable resources. Photovoltaic (PV) technology most favorable option electricity buildi...

Ubiquitous coverage is one of the most important goals for mobile communication networks. To achieve this, integration space, air, and ground networks highly demanded, which expects to become enabling technologies 6G However, integrated network faces demand orders magnitude improvement in coverage, access capability service capability, could not be achieved under existing management mechanisms....
