The edge effect: lateral habitat ecology of an alluvial river flood plain
We describe the ecology of off-channel or "lateral" habitats as key attributes of the Shifting Habitat Mosaic (SHM) of a river flood plain at the Nyack Research Natural Area in northwestern Montana. Our working hypothesis was that lateral habitats are important to the cycling of energy and …

Prediction model for the onset of edge-effect delamination at holes in composite laminates
… laminates are prone to delamination at free edges, straight edges or at holes, due to the mismatch at interfaces where two adjacent plies have different fiber orientations and/or different material properties. The linear analysis of the mismatch at the edge results in a mathematical …

Numerical Study For Acoustic Micro-Imaging Of Three Dimensional Microelectronic Packages
… all the developments. The physical mechanics of edge effects was studied and verified against experimental data. A direct relationship between transducer spot size and edge effect severity was established. At regions with edge effect, the acoustic pulse interfacing with the solder bump edge is …

The investigation of edge effects within ragmented forest islands in Short Hills Provincial Park
… It has also been observed that elevated areas of edge habitat occur within fragmented landscapes. Spatial and temporal edge effects were investigated in four areas designated as Nature Reserve Zones within Short Hills Provincial Park, near St. Catharines, Ontario. Random sampling along exposed …

Inhomogeneous Totally Asymmetric Simple Exclusion Processes: Simulations, Theory and Application to Protein Synthesis
… of codons), we are especially interested in the effects of a finite number of slow codons to the overall stationary current. To study this matter systematically, we first explore the effects of local inhomogeneities, i.e., one or two slow sites of hopping rate q<1 in TASEP for particles of size …

Random delamination of graphite/epoxy laminated composites : stress analysis, failure criteria, experimental characterization and stochastic modeling
… is developed to determine the three-dimensional edge effect stresses around pin-loaded holes in symmetric laminated composites. The stress state around the holes is divided into two parts, one the in-plane stress state determined using the Classical Laminated Plate Theory (CLPT) and the other the …

Pollinator Abundance at Solar Farms in Alberta, Canada
… panels and target mowing to beneath panels. Edges of solar sites experience less frequent vegetation control which could create an edge effect and influence how bees assemble within a solar site. Four solar farms in Alberta, Canada were sampled using pan and vane traps to collect bee …

Plant Response to the Barstow to Las Vegas Motorcycle Race of November, 1974
… positive response was held by annuals due to the edge effect. Differences in percent species composition, density, and cover indicate a change in diversity and stability of the perennial plant vegetation.</p>

Interlayer Defect Effects on the Phonon Properties of Bilayer Graphene and its Nanoribbon
… increasing amount of defect concentration. The edge effect on the localized phonon modes has also been discussed for bilayer armchair graphene nanoribbons (BiAGNRs). The impact of defects on the phonon conduction properties has also been studied for BiAGNRs. My investigated results can be …

Two-dimensional Mapping of Interface Thermal Resistance by Transient Thermal Impedance Measurement
… thermal model was built to investigate the effects of thermal sensor packaging materials and structural parameters on the sensitivity of the measurement technique. Based on this model, we increased the detection sensitivity of the sensor by modifying the size of the sensor substrate, the …

Multiple dominance and interface operations
… role in the resolution of two puzzles: The right-edge restriction on right-node raising and selective island effects in A'-movement. I develop a linearization algorithm which is locally sensitive to complete dominance, and show how, when applied to right-node raising structures, it predicts the …

Modeling, analysis, and design of high-frequency high-density low-profile power transformers
… energy storage in transformer by taking the skin effect, proximity effect, and edge effect into account. The characteristics of winding arrangements (interleaved or sandwiched, balanced or unbalanced) with different types of wire (solid wire, Litz wire, and printed wire) are accurately predicted. …

Scale and texture in digital image classification
… adjacent classes and is most obvious near class edges, especially for smooth classes. In rough classes between-class variance may not differ much from within-class variance. Errors in classifications using texture, therefore, are most likely associated with, class edges; however, investigators …

Breeding bird populations in relation to the vegetation structure of abandoned contour mines in Southwest Virginia
… areas, apparently reflecting a decrease in the edge effect. Several sets of equations for population parameters of the disturbed and total study areas are presented for use in habitat evaluation. Relationships revealed for bird population parameters of the disturbed and total study areas suggest …

Automatic selection of optimal window size and shape for texture analysis
… relationship between texture and scale, and its effects on image classification. This study involved creating a model that automatically selected windows of optimal size according to the location of a pixel within a land cover region and the texture of the surrounding pixels. Large windows were …

Ecological and taxonomic studies of ectomycorrhizal fungi associated with Aspen
… in 4 years. Fruitings exhibited a clustered “edge effect" at the canopy perimeter, in contrast to their mycorrhizae, which were found throughout the stand. The unusual vertical distribution of mycorrhizae to a depth of 48 cm, with few in the top 16 cm of soil is most likely due to moisture, …

Waterfowl Pair and Brood Use of Dug brood Complexes in East-Central South Dakota
… in excavated ponds and channels, and a greater edge effect in modified wetlands than in control wetlands. Pair and brood use of modified wetlands was found to increase as surface water area, open water area, and water depth increased. Pheasants (Phasianus colchicus), mallards (Anas …
