human activities induced changes in land cover/use have extensive impacts on the landscape. in recent years, these changes had an increasingly growth due to irrational use of the natural resources in iran. hence, considering the negative effects of the inappropriate use of land and land-use change, understanding of the landscape changes over time is necessary to planning and implementation of s...

animals that can estimate their desirable habitat quality are better able to accordingly adapt their life behaviors. the life cycles of parasitoids are so closely adapted as to match their hosts life behavior. among the various host-parasitoid interactions, a peculiarity is the seasonal synchrony between host and parasitoid activity. the foraging and oviposition behaviors of lysiphlebus fabarum...

The proposed method is to recognize objects based on application of Local Steering Kernels (LSK) as Descriptors to the image patches. In order to represent the local properties of the images, patch is to be extracted where the variations occur in an image. To find the interest point, Wavelet based Salient Point detector is used. Local Steering Kernel is then applied to the resultant pixels, in ...

The effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. The third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. Equations of motion of the plate are obtained with the help of calculus of variation. Parametric study ...

24 This laboratory study describes the sediment patterns formed in a sand bed 25 around circular patches of rigid vertical cylinders, representing a patch of reedy 26 emergent vegetation. The patch diameter was much smaller than the channel 27 width. Two patch densities (solid volume fraction 3% and 10%) and two patch 28 diameters (22 and 10 cm) were considered. For flows above the threshold of...
