Physics-informed neural network (PINN) has recently gained increasing interest in computational mechanics. This work extends the PINN to solid mechanics problems. Our focus will be on investigation of various formulation and programming techniques, when governing equations are implemented. Two prevailingly used physics-informed loss functions for PINN-based implemented examined. Numerical examples ranging from 1D 3D problems presented show performance The programs built via Python with...

Precise navigation in agricultural applications necessitates accurate guidance from the seedling belt, which Global Positioning System (GPS) alone cannot provide. The overlapping leaves of Chinese cabbage (Brassica pekinensis Rupr.) present significant challenges for belt fitting due to difficulties plant identification. This study aims address these by improving You Only Look Once (YOLO) v7 model with a novel approach that decouples its network head deriving Faster-Regions Convolutional...

Global coffee production experiences detrimental impacts of climate change. Weather index insurance (WII) offers an opportunity for farmers to mitigate the risks in and motivate them adopt sustainable farming practices. This study explores Vietnamese farmers' willingness participate pay WII schemes coffee. A contingent valuation survey was employed on a sample 151 from two largest areas: Lam Dong Dak Lak provinces. The findings revealed that are willing pay, average, US$92.30 per policy...

Deep learning (DL) relies heavily on data, and the quality of data influences its performance significantly. However, obtaining high-quality, well-annotated datasets can be challenging or even impossible in many real-world applications, such as structural risk estimation medical diagnosis. This presents a significant barrier to practical implementation DL these fields. Physics-guided deep (PGDL) is novel type that integrate physics laws train neural networks. applied any systems are...

This study examines Cambodian farmers’ demand for weather index insurance (WII), an innovative financial product, managing climate change-related risks. Rice and cassava farmers in Battambang Province of Cambodia were interviewed to understand their preferences WII. We applied a binary logistic model quantify the factors that influence WII demand. discovered marital status off-farm labor are crucial impact More importantly, we also investigated gender differences, considering critical role...
