In this paper we studied and reviewed two algorithms Edge based Image Restoration and Progressive Image Inpaintig based on Wavelet Transform. These algorithms uses patch based technique for completing missing region of the image with the help of surrounding information that already is present in original image. We came up with new concept which is extension of progressive method by using Adapti...

In this paper, hybrid modeling of Micro-strip antenna is presented. Broadband frequency of operation demonstrated by single geometry .for broadening the bandwidth and maximum directional gain (6.6dBi 8dBi) gap-coupled multi-resonator loaded on parasitic and active patch. The geometry of a single probe fed rectangular Micro-strip antenna incorporating a slot and gap coupled with parasitic and ac...

Optimal foraging models predict how an organism allocates its time and energy while foraging for aggregated resources. These models have been successfully applied to organisms such as predators looking for prey, female parasitoids looking for hosts, or herbivorous searching for food. In this study, information use and patch time allocation were investigated using male parasitoids looking for ma...

Agricultural intensification has profoundly changed agricultural landscapes with important biodiversity impacts. There is increasing knowledge on the general effects of landscape structure and management practices plant animal species but understanding role surrounding for patch-scale more complex. While it can be reasonably assumed, that adjacent habitats are than distant ones, importance ofte...

When a patch is placed close to the fed patch, get excited due to parasitic coupling between the two elements. This proposed work presents theoretical analysis of rectangular gap coupled microstrip patch antenna (R-GCMSA) using circuit concept model, and the effect of gap(g), feed width(W f), and feed length on performance of the impedance bandwidth is also studied, it is observe as the gap bet...

This paper explores folded patch antennas for the development of low-cost and wireless smart-skin sensors that monitor the strain in metallic structures. When the patch antenna is under strain/deformation, its resonance frequency varies accordingly. The variation can be easily interrogated and recorded by a wireless reader that also provides power for the antenna operation. The patch antenna ad...

We determine the critical patch size below which extinction occurs for populations living in one-dimensional habitats surrounded by completely hostile environments in the presence of environmental fluctuations. The population dynamics is reformulated in terms of a stochastic reaction-diffusion equation and is reduced to a deterministic equation that incorporates the systematic contributions of ...

Habitat fragmentation and land use changes are causing major biodiversity losses. Connectivity of the landscape or environmental conditions alone can shape biodiversity patterns. In nature, however, local habitat characteristics are often intrinsically linked to a specific connectivity. Such a link is evident in riverine ecosystems, where hierarchical dendritic structures command related scalin...
