Coefficient of Variation from Vegetation Index for Sugarcane Population and Stalk Evaluation

Modified signed log-likelihood test for the coefficient of variation of an inverse Gaussian population

In this paper, we consider the problem of two sided hypothesis testing for the parameter of coefficient of variation of an inverse Gaussian population. An approach used here is the modified signed log-likelihood ratio (MSLR) method which is the modification of traditional signed log-likelihood ratio test. Previous works show that this proposed method has third-order accuracy whereas the traditi...

Meris Global Vegetation Index: Evaluation and Performance

This paper overviews the evaluation and the performance of the Medium Resolution Imaging Spectrometer (MERIS) Global Vegetation Index (MGVI) algorithm which is implemented in the MERIS ground segment as the main land surface product, also called the Top Of Atmosphere Vegetation Index (TOAVI). MGVI values represent the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) which act as...

Available Methods for Assessing Varietal Resistance to Sugarcane Stalk Borers

Sugarcane is semiperennial and produces considerable biomass, forming an ideal habitat for insects. Most insects do not affect crops, but some compete with humans for sugar and by-products. Sugarcane stalkborers are key pests of this crop worldwide because they feed directly on the vegetative tissues that store sucrose, allowing the introduction of micro-organisms that affect yield and quality....
