The objective of this research is to assess the multitemporal very high resolution single polarization SAR data for urban land cover/land-use mapping using a novel knowledge-based SEM algorithm. Three-date RADARSAT-2 ultra-fine beam SAR data were collected over the rural-urban fringe of Greater Toronto Area. A modified Stochastic Expectation-Maximization (SEM) algorithm which employs an adaptiv...
strong sentiment against the phenomenon known as “urban sprawl” has emerged in the United States over the past few years. Critics of sprawl argue that urban expansion encroaches excessively on agricultural land, leading to a loss of amenity benefits from open space as well as the depletion of scarce farmland resources. The critics also argue that the long commutes generated by urban expansion c...
Quantifying landscape pattern and its change are essential for the monitoring and assessment of environmental consequences of urban area. This paper aims to analyze spatiotemporal patterns of urban landscape changes in Kathmandu Valley, Nepal by combining remote sensing, GIS and landscape metrics. Multi-temporal satellite images from high resolution (CORONA, SPIN and IKONOS) to moderate resolut...
Novel approaches based on windowed Fourier transform for demodulation of fringe patterns were previously presented [Appl. Opt. 43, 2695-2702 (2004)], where extraction of phase and phase derivatives from either phase-shifted fringe patterns or a single-carrier fringe pattern was the main focus. I show that the same methods can be applied to process a single closed-fringe pattern in either noise ...
In research of photoelasticity, photoelastic fringe patterns are obtained through a circular polariscope with different optical arrangements and they are processed with image processing techniques in a personal computer. Image processing techniques are reviewed and discussed for stress analysis of the photoelastic fringes in this paper. The image processing techniques include fringe sharpening,...
fringe encodes a glycosyltransferase that modulates the ability of the Notch receptor to be activated by its ligands. We describe studies of fringe function during early stages of Drosophila oogenesis. Animals mutant for hypomorphic alleles of fringe contain follicles with an incorrect number of germline cells, which are separated by abnormally long and disorganized stalks. Analysis of clones o...
Context Small mammals may traverse the urban fringe and use both natural anthropogenic resources. In Australia, human commensal black rats (Rattus rattus) native long-nosed bandicoots (Perameles nasuta) are important tick hosts, which can be found persisting at fringe, leading to human–wildlife conflict.Aims We aimed (1) determine relative activity of small in yards associations with yard attri...
