In recent decades, many spectral vegetation indices (SVIs) have been proposed to estimate the leaf nitrogen concentration (LNC) of crops. However, most of these indices were based on the field hyperspectral reflectance. To test whether they can be used in aerial remote platform effectively, in this work a comparison of the sensitivity between several broad-band and red edge-based SVIs to LNC is...
let $g=(v(g),e(g))$ be a simple connected graph with vertex set $v(g)$ and edge set $e(g)$. the (first) edge-hyper wiener index of the graph $g$ is defined as: $$ww_{e}(g)=sum_{{f,g}subseteq e(g)}(d_{e}(f,g|g)+d_{e}^{2}(f,g|g))=frac{1}{2}sum_{fin e(g)}(d_{e}(f|g)+d^{2}_{e}(f|g)),$$ where $d_{e}(f,g|g)$ denotes the distance between the edges $f=xy$ and $g=uv$ in $e(g)$ and $d_{e}(f|g)=s...
Tropical deforestation is leading not only to losses of biodiversity but also to regional losses of vegetation productivity. However, in many areas the deforestation process is usually accompanied by a fast forest regeneration that produces a mosaic of forest patches in different successional stages. These successional stages have different productivities owing primarily to differences in speci...
The hyper-arid Atacama Desert is one of the most extreme environments for life and only few species have evolved to survive its aridness. One such species is the tree Prosopis tamarugo Phil. Because Tamarugo completely depends on groundwater, it is being threatened by the high water demand from the Chilean mining industry and the human consumption. In this paper, we identified the most importan...
Edge detection has attracted the attention of many researchers and is one of the most important areas in low level computer vision. In recent years, the focus of edge detection has shifted from grayscale single component images to multicomponent color images that utilize the inter-spectral correlation of the neighboring color samples to eliminate color artifacts and increase the accuracy of edg...
The emergence of satellites covering new electromagnetic wavelengthsallowed developing different vegetation indices, enabling the study theircorrelation with grain yield. In this sense, aimed to evaluate accuracy between mean values seven indices and corn yield in field by applying linear regression equations. NDVI, NDRE, GNDVI, GRNDVI, PNDVI were used, changes proposed equations GRNDVI PNDVI, ...
ABSTRACT Let G=(V,E) be a simple connected graph with vertex set V and edge set E. The Szeged index of G is defined by where respectively is the number of vertices of G closer to u (respectively v) than v (respectively u). If S is a set of size let V be the set of all subsets of S of size 3. Then we define t...
105 inTroducTion Civilian Tactical Emergency Medical Support (TEMS) has a long history in the United States. Enormous progress has been made during the past ten years in developing professional and operational standards within the field. However, to date, there still exists no standard of care within TEMS specifically, and more broadly for high threat pre-hospital trauma care. Current civilian ...
