We present the preferential filtering method for gravity anomaly separation based on Green equivalent-layer concept and Wiener filter. Compared to the conventional upward continuation and the preferential continuation, the preferential filtering method has the advantage of no requirement of continuation height. The method was tested both on the synthetic gravity data of a model of multiple rect...

—RADARSAT-1 synthetic aperture radar data, speckle reduction, and texture measures provided for separation among forest types within the Twin Cities metropolitan area, MN, USA. The highest transformed divergence values for 16-bit data resulted from speckle filtering while the highest values for 8-bit data resulted from the orthorectified image, before and after performing a histogram stretch. F...

Image separation is defined as decomposing a real world image mixture into individual images objects. Independent component analysis is an active area of research and is being utilized for its capability in statistically independent separation images. Neural network algorithm ICA has been used to extract interference and mixed images and a very rapid developed statistical method during last few...

We present a method for reducing the treewidth of a graph while preserving all the minimal s − t separators. This technique turns out to be very useful for establishing the fixedparameter tractability of constrained separation and bipartization problems. To demonstrate the power of this technique, we prove the fixed-parameter tractability of a number of well-known separation and bipartization p...

We report an experimental study on shape deformations of ternary vesicles undergoing phase separation under an osmotic pressure difference. The phase separation on various shape vesicles causes unique shape-deformation branches. In the domain coarsening stage, prolate, discocyte, and starfish vesicles show a shape convergence to discocytes, whereas a pearling instability is observed in tube ves...

This paper presents an investigation into language constructs for supporting improved separation of crosscutting concerns. Traditionally, this separation has been performed using metaprogramming and other related techniques. A growing area of research, called aspect-oriented software development, offers a new approach. We describe several distinctive characteristics of the two approaches with r...

This paper presents visual analysis tools intended to aid researchers and policy makers by producing a visual representation of air traffic density and, by taking into account the required aircraft separation minima, the conflict probability. The tools support visualization of time-varying air traffic density over an area of interest using different time granularity. This visual analysis platfo...

Crack growth along an interface joining an elastic-plastic solid to a solid that does not yield plastically is studied numerically, accounting for mixed mode loading under conditions of small scale yielding. The fracture process is represented in terms of a cohesive zone model, for which the work of separation per unit area and the peak stress required for separation are basic parameters; but w...

This study examines stable isotope ratios of carbon and nitrogen in bone collagen and the elemental concentrations of strontium in the bone mineral of terrestrial vertebrates fi'om a variety of ecosystems. Documentation of the separation oftrophic levels by these indices is essential for the assessment of the trophic position of prehistoric humans. Particular emphasis is given to carnivores in ...

We demonstrate a wide-angle electron beam splitter capable of producing 1 cm beam separation at the detection plane. The beam splitter utilizes a nanofabricated periodic grating in combination with a bi-prism element. In contrast to devices utilizing only bi-prism elements, the use of the periodic grating causes amplitude, and not wavefront, splitting. Even at maximum separation, beam profiles ...
