New Spectral Indices as Indicators of Carotenoids Content

Applied Mechanics and Materials, 2012
Carotenoids play a key role in adaptation of plants to light stress and other unfavorable ecological conditions. Remote sensing of carotenoids content still not well developed due to the absorptions overlap of chlorophyll a and carotenoids in the visible spectral range.

Laplacian Spectral Indices of Hexacyclic Systems

Match Communications in Mathematical and in Computer Chemistry
The hexacyclic system graph Fn is the graph derived from a linear hexagonal chain Ln with n > 1 hexagons by identifying two pairs of ends of Ln. The M¨obious hexacyclic system graph Mn is the graph derived from a linear hexagonal chain Ln with n > 1 hexagons by identifying two pairs of ends of Ln with a twist.

Spectral indices for precise agriculture monitoring

International Journal of Remote Sensing, 2006
This paper presents two main objectives of a multi‐year study applying remote sensing to precision agriculture: (1) developing new spectral indices for wheat monitoring, and (2) producing an interpretation key for mapping vegetation features with spectral indices.

Spectral indices for yellow canola flowers

International Journal of Remote Sensing, 2015
Reproductive growth, such as by flowers, may contribute to a canopy-level signal yet there are no current indices that measure variation in flowering. This study was conducted to determine how flowers influence the overall canopy signal and what bands of light may be useful for estimating variation in flower density and leaf area index LAI. The effects
