The development of small, autonomous UAVs that can operate in complex environments as part of large coordinated groups will enable many new applications at fractions of the cost of current systems. A fleet of fixed-wing aircraft has been developed to create an intelligent aerial platform that has demonstrated various autonomous capabilities. By means of a downward-looking camera, a single aircr...

A study was carried out to investigate the utility of airborne hyperspectral and satellite L-band Synthetic Aperture Radar (SAR) data for estimating fractional coverages of herbaceous, coastal scrub, and bare ground cover types on the central California coast. Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) imagery collected in September of 2008 and Phased Array L-band SAR (PALSAR) (HH-...

[1] Six different geophysical investigations, (1) ground-penetrating radar, (2) DC resistivity sounding, (3) seismic refraction, (4) very low frequency (VHF) electromagnetic, (5) helicopter borne electromagnetic (HEM), and (6) transient electromagnetic (TEM) techniques, were employed to obtain information on the ice body properties of pingos near Fairbanks, Alaska. The surface nuclear magnetic ...

Insecticidal lamps Internet of things (ILs-IoTs) has attracted considerable attention for its applications in pest control to achieve green agriculture. However, ILs-IoTs cannot provide a perfect solution the migratory outbreak if ILs are fixed on ground. In this paper, we embed unmanned aerial vehicles (UAVs) as mobile nodes, which can be rapidly landed ground kill agricultural pests, and UAVs...

This article presents a controlled experiment that compares the behavior of the testing techniques Statement Coverage and All Uses. The design of this experiment is typical for a factor with two alternatives. A total of 14 subjects carry out tests on a single program. The results indicate that there is enough statistical evidence to state that the cost of executing All Uses is higher than that ...

This paper describes SimpleNLG for German, a surface realisation engine for German based on SimpleNLG (Gatt and Reiter, 2009). Several features of the syntax of German and their implementation within the current framework are discussed, with a special focus on word order phenomena. Grammatical coverage of the system is demonstrated by means of selected examples.

Forests provide potentially important bee habitat, but little research has been done on forest bee diversity and the relative effectiveness of bee sampling methods in this environment. Bee diversity and sampling methodology were studied in an Illinois, USA upland oak-hickory forest using elevated and ground-level pan traps, malaise traps, and vane traps. 854 bees and 55 bee species were collect...

Based on remote sensing data of vegetation coverage, observation basic meteorological elements, and support vector machine (SVM) method, this study develops an analysis model elements influence coverage (MEVC). The variations for the changes are identified utilizing five (temperature, precipitation, relative humidity, sunshine hour, ground temperature) in SVM model. performance is also evaluate...

Coverage-guided fuzzing is one of the most effective approaches for discovering software defects and vulnerabilities. It executes all mutated tests from seed inputs to expose coverage-increasing tests. However, executing incurs significant performance penalties---most are discarded because they do not increase code coverage. Thus, determining if a test increases coverage without actually it ben...
