Mapping spatial data is essential for the monitoring of flooded areas, prognosis hazards and prevention flood risks. The Ganges River Delta, Bangladesh, world’s largest river delta prone to floods that impact social–natural systems through losses lives damage infrastructure landscapes. Millions people living in this region are vulnerable repetitive due exposure, high susceptibility low resilience. Cumulative effects monsoon climate, rainfall, tropical cyclones hydrogeologic setting Delta increase probability floods. While engineering methods mitigation include practical solutions (technical construction dams, bridges hydraulic drains), regulation traffic land planning support systems, geoinformation rely on modelling remote sensing (RS) evaluate dynamics hazards. Geoinformation indispensable mapping catchments areas visualization affected regions real-time monitoring, addition implementing developing emergency plans vulnerability assessment warning supported by RS data.

Flavor Identification Based on Olfactory-Taste Synesthesia Model and Hybrid Convolutional Neural Network-Random Forest

Measurement Science and Technology, Journal Year: 2024, Volume and Issue: 35(11), P. 115115 - 115115

Published: Aug. 15, 2024

Abstract The bionic-based electronic nose (e-nose) and tongue (e-tongue) show satisfactory performance in flavor analysis. Traditional analysis of the e-nose e-tongue systems focuses on data fusion, effects bionic characteristics are rarely studied. Motivated by this, a method, including an olfactory-taste synesthesia model (OTSM) convolutional neural network-random forest (CNN-RF), is proposed for effective identification substances. OTSM developed human nerve conduction mechanisms to enhance combined with CNN-RF identification. results that, first, when stimulated data, physiological 1/ f synchronization shown using OTSM. enhancement fusion system validated synchronization. Second, fully connected layer CNN replaced RF improve Finally, evaluated comparison other recognition models ablation studies confirm its effectiveness. By comparison, best performance, accuracies 96.67%, 95.00%, F 1 -scores 96.65%, 96.66%, 94.95%, kappa coefficients 96.03%, 96.10%, 93.44%, five beers, apples, four mixed solutions, respectively, obtained CNN-RF.

STGRL: SNN based Two-Stage Geomagnetic Road Localization Method

Measurement Science and Technology, Journal Year: 2024, Volume and Issue: 36(1), P. 016322 - 016322

Published: Oct. 30, 2024

Abstract Geomagnetic navigation is a widely used positioning method capable of correcting the cumulative errors odometers and inertial systems, thereby ensuring long-distance for vehicles in GPS-denied environments. However, common geomagnetic road algorithms are susceptible to measurement noise, which hinder improvements efficiency accuracy. To address this issue, paper proposes Siamese Neural Network (SNN) based two-stage localization method. First, attitude angle information combined with scalar vector value establish reference database increase feature dimensions matching. Then, we use Random Forest algorithm perform coarse matching data sequence determine current road, balancing increased computational load resulting from addition dimensions. Finally, further reduce impact random employs SNN on Transformer Encoder fine sequence. Experiments show that compared existing methods, average absolute error our has been reduced 32.36 m 4.07 m, kept within an acceptable range.
