In order to investigate the effects of range management plans on species diversity, richness and evenness in Semirum rangelands, 52 sites (28 with treated plan and 24 without treated plan) were selected. The non-parametric indices for species richness (Margalof, Menhinick, Jacknife and counting method) and species diversity (Simpson, Camargo, Smith and Wilson and modified Nee) were compared in ...
ecological capability evaluation and landuse planning can determine the best landuses and are important for the proper planning and sustainable development. there are various methods for ecological capability evaluation. in this research have been studied two methods (land use planning method with makhdoom ecological modsels) and (geomorphology method) for ecological capability evaluation in ne...

Abstract—In this paper, a CMOS differential operational transresistance amplifier (OTRA) is presented. The amplifier is designed and implemented in a standard umc90-nm CMOS technology. The differential OTRA provides wider bandwidth at high gain. It also shows much better rise and fall time and exhibits a very good input current dynamic range of 50 to 50 μA. The OTRA can be used in many analog V...
Photographing scenes with high dynamic range (HDR) poses great challenges to consumer cameras with their limited sensor bit depth. To address this, Zhao et al. recently proposed a novel sensor concept – the modulo camera – which captures the least significant bits of the recorded scene instead of going into saturation. Similar to conventional pipelines, HDR images can be reconstructed from mult...
As captured imagery grows in resolution to gigapixels, increases in dynamic range beyond what can be displayed, and encompasses wider fields of view, there is a need for the viewer of such imagery to take on many of the roles traditionally relegated to the camera. Fully exploring such imagery requires a software camera. One such software camera is HD View. We discuss the need for the evolution ...
| The MeerKAT is a precursor for the Bsmall dish plus single-pixel wide-band feed[ scenario for the Square Kilometre Array (SKA). The current goal specification is for an array of 80 12-m dishes operating over a continuous frequency range of 0.7–10 GHz, thus the individual receptors match the SKA draft specification for midband dishes. The proposed array configuration is centrally concentrated ...
Aims. The goal of this work is a detailed study of the nearby, low power radio galaxy B2 1144+35B. Methods. For this purpose, we performed new Very Long Baseline Array (VLBA) and Very Large Array (VLA) observations. Results. This source has several properties (bright, nearby, large range of spatial structures, visible counterjet, etc.) that make it an excellent astrophysical laboratory for the ...
The direct images of giant extrasolar planets recently obtained around several main sequence stars represent a major step in the study of planetary systems. These high-dynamic range images are among the most striking results obtained by the current generation of high angular resolution instruments, which will be superseded by a new generation of instruments in the coming years. It is therefore ...
