The citrus industry in Florida is being threatened by some devastating diseases, one of which is called citrus greening, also known as Huanglongbing (HLB). Timely and location-specific detection and monitoring of the infected citrus trees are required for efficient disease control, while reducing risks of the disease being spread. Satellite images were used to detect citrus greening disease over large...
The paper is focused on analyzing 20 heart sound samples, including patients with coronary disease and healthy persons. Short Time Flourier Transform (STFT) is adopted for the analysis, since Flourier Transform (FT) has its limitations as a tool in analyzing heart sound signals which as biological signals are weak and nonstable. The study demonstrates that the heart sounds of patients with coronary...
This paper gives a new way of recognizing and sorting of ECG signals, using ECG signals analysis and improved back propagation artificial neural network. Firstly, the ECG signals has to be digitally filtered to eliminating the 50 Hz noise. The neural network adopted is improved back propagation three-layer artificial neural network, with an optimized BPN4-3-2 network topology. Get the four characteristic...
