Scaling Up and Exploring Marsh (SUEM)
… years at Sapelo Island located in Georgia. The sampling area was approximately 3,200 square meters. Annually around 10,000 images were captured of a sampling area. Manually examining of a substantial amount of spatially explicit data is very laborious and resource consuming. The idea is to …

Efficacy of the Microtally® Mitt for sampling of beef carcasses
… pathogenically contaminated products. Several sampling methods, including N60 excision, N60 Plus™, and continuous and manual sampling devices using the Microtally® Swab or Mitt, are widely used in industry for verification testing. Among these, the Microtally® Mitt (MT-Mitt) is a sterile cloth …

Application of Mineral Magnetic Measurements as a Pollution Proxy for Urban Road Deposited Sediment
… linked to regional monitoring of air sampling units (ASU) (n = 208). A suite of analytical approaches, namely mineral magnetism, laser diffraction, X-Ray Fluorescence spectroscopy (XRF), Scanning Electron Microscopy (SEM) and Loss on Ignition (LOI), were employed to characterize sample …

Aquatic Turtle Community Dynamics in Relation to Reintroduction of Alligator Snapping Turtles, Macrochelys Temminckii
… be lowered by dispersal of animals away from the sampling area. Among the three rivers and three tributaries sampled, Pond Creek, a tributary of the Caney River, had the highest diversity. Big Creek, a tributary of the Verdigris River, supported a turtle community that was comparatively dissimilar …

The Area Sampling Machine
… the shading at that sampled point. The sampling process can be thought of as a visibility test along the path of the ray having zero cross sectional area. Recent photorealistic image synthesis work has generally ignored the results from earlier visibility determination research. In the …

Autonomous Sample Collection Using Image-Based 3D Reconstructions
… hardware. To ease the operator burden during sampling the scoop system is paired with new semi-autonomous and fully autonomous collection techniques. These are derived from data provided by colored 3D point clouds produced via image-based 3D reconstructions. A custom robotic mobility platform, …

Priority queuing for raw material receiving
… and priority queuing was developed, highlighting areas for improvement. Based on insight gained from the tool, a plan was established which can reduce turnaround time (TAT) by 50% and work in process (WIP) by 45% in the raw material sampling area. The improvements will not only provide financial …

Reproductive biology, growth and mortality of tylochromis Bangwelensis (Regan, 1920) in Bangweulu lakes and swamps complex fishery.
… are under or over exploited in the fishery. A sampling area (S 11o 19’ 24.6” and E 029o 34’ 16.9”) that represented the main landing sites was selected. The fish samples were procured from the local fisher’s catches for seven months from March 2019 to September 2019. Length measurements were …

Multi-scale analysis of urban wetland changes using satellite remote sensing techniques
… changes in the Kansas City metropolitan area with analyses at various spatial and temporal scales. Not many studies fully addressed multi-scale urban wetland-cover dynamics in both the temporal and spatial dimension. The objective was to understand how major driving factors - human …

Comparative Phylogeography of Central African Duikers Using Non-invasive Sampling Methods
… African duikers (subfamily Cephalophinae). The sampling strategy consisted of collecting geo-referenced duiker feces across 43 sites and seven countries. However, several challenges related to the use of non-invasive samples needed to be addressed prior to large scale DNA amplification. First, …

Raman microscopy studies of carbon particles from diesel particulate matter (DPM) and coal dust
… obtain the most reproducible integrated spectral areas. A rotation stage was developed and employed to spin the specimens during analysis, resulting in a larger sampling area. This resulted in a more representative sampling regime for the heterogeneous specimens and a considerable improvement in …

Major and trace element characterization and correlation of the Sentinel Butte Ash/Bentonite (Paleocene), McKenzie County, North Dakota
… elements samples collected outside of the random sampling area were correlated with the Sentinel Butte ash/bentanite. All but three of those samples were found to be correlative with the unknown ash/bentonite, expanding the known areal extent of the unit. </p>

The economic and ecological sustainability of the Amazonian timber industry
… higher gross revenue productivity per unit area and were more likely to inconsistently report areas of unlogged forest set-asides as required by Brazilian law. Selective logging leads to several forms of collateral damage (CD) to the residual forest stand. This pattern of structural …

Influence of habitat complexity on diversity and community structure of arboreal spiders in grassland-shrub systems
… factors. Changes in the topography of the sampling area affected the local plant communities of shrubs across a recognized elevational gradient, which correlated to habitat zones for arboreal spiders in the local area.

The development and application of statistical sampling regime to map out hydrocarbons in sediments.
… investigates and develops a stratified random sampling design for sediments in an offshore oil field environment. The sampling area was partitioned equally into sixteen zones. Stratification was based on the near-field and far-field areas, and the number of samples in each zone was chosen by …

Optimizing Trichogramma ostriniae (Hymenoptera: Trichogrammatidae) releases to control European corn borer, Ostrinia nubilalis (Lepidoptera: Crambidae) in bell pepper
… dispersed quickly throughout the 0.4 ha (1 acre) sampling area. Parasitism and sticky card captures were highest close to the release point and decreased with increasing distance. Sticky card data were a good fit to the diffusion model used (r² > 0.90) for all but two sampling dates. In 2005 …
