Successful determination of soil texture using reflectance spectroscopy across Visible and Near-Infrared (VNIR, 400–1200 nm) and Short-Wave-Infrared (SWIR, 1200–2500 nm) ranges depends largely on the selection of a suitable data mining algorithm. The objective of this research was to explore whether the new Memory-Based Learning (MBL) method performs better than the other methods, namely: Parti...
Grassland ecosystems cover around 40% of the entire Earth’s surface. Therefore, it is necessary to guarantee good grassland management at field scale in order to improve its conservation and to achieve optimal growth. This study identified the most appropriate statistical strategy, between partial least squares regression (PLSR) and narrow vegetation indices, for estimating the structural and b...
Anthocyanins are severity indicators for apple mosaic disease and can be used to monitor tree health. However, most of the current studies have focused on healthy leaves, few estimated anthocyanin content in diseased leaves. In this study, we obtained hyperspectral data leaves with disease, analyzed spectral characteristics different degrees Mosaic constructed screened index sensitive content, ...
The objective of this study was to find an efficient method for measuring the total soluble solid content (TSSC) and water “Luogang” orange. Quick, accurate, nondestructive detection tools (VIS/NIR spectroscopy, NIR machine vision, electronic nose), four data processing methods (Savitzky–Golay (SG), genetic algorithm (GA), multi-source information fusion (MIF), convolutional neural network (CNN...
Earth's future carbon balance and regional carbon exchange dynamics are inextricably linked to plant photosynthesis. Spectral vegetation indices are widely used as proxies for vegetation greenness and to estimate state variables such as vegetation cover and leaf area index. However, the capacity of green leaves to take up carbon can change throughout the season. We quantify photosynthetic capac...
Rice yield is not only influenced by factors of varieties and managements, but also environmental factors. In this study, agronomic trait data rice climate in eastern China were collected, yields predicted using a variety algorithms, including the non-linear tool feed-forward backpropagation neural networks (FFBN) linear model partial least squares regression (PLSR). The results showed that bot...
PURPOSE Chronic Lymphocytic Leukemia (CLL) is defined by a perturbed B-cell receptor-mediated signaling machinery. We aimed to model differential signaling behavior between B cells from CLL and healthy individuals to pinpoint modes of dysregulation. EXPERIMENTAL DESIGN We developed an experimental methodology combining immunophenotyping, multiplexed phosphospecific flow cytometry, and multifa...
Aims: To determine and compare the bacteriological quality of frozen chicken sold in Capital cities South Eastern States Nigeria. Method: A total 150 samples (frozen chicken) were collected from different (Abakaliki, Awka, Enugu, Owerri Umuahia) five (5) Nigeria, which 30 each State. The Aerobic Plate Counts (APC), Total Coliform (TCC), Psychrotrophic (PPC), Escherichia coli counts, Staphyococc...
