Climate change is the main factor affecting country's vulnerability, meanwhile, it also a complicated and nonlinear dynamic system. In order to solve this complex problem, paper first uses analytic hierarchy process (AHP) natural breakpoint method (NBM) implement an AHP-NBM comprehensive evaluation model assess national vulnerability. By using ArcGIS, vulnerability scores are classified divided into three levels: fragile, vulnerable, stable. Then, BP neural network prediction which based on...
Core Ideas Our method can estimate groundwater recharge through multiple contrasting lithological layers. Both human activities and natural aquifer character impact flow transport. Geomembrane liners effectively control the leakage from Yongding River. The ecological restoration of River alleviate local water deficit. Reclaimed was discharged into channels as water. Pollutants such may leak underlying put environment at risk. estimation under different possible river lining conditions...
Nitrate pollution has become an environmental problem of global concern. One effective way for controlling the nitrate water is to identify source and reduce input nitrate. This study traces quantifies sources contamination groundwater surface in northeastern suburbs Beijing, where emergency zone located. Nitrogen oxygen stable isotope analysis, geospatial analysis techniques, principal component correlation a Bayesian mixing model were used achieve our goals. The results show that main...
Rural land consolidation (RLC) is one of the largest organized activities affecting use and terrestrial ecosystems, its effect on ecosystems' spatial patterns service functions has been closely scrutinized. Previous studies have primarily focused response ecosystem services (ES), but associated changes in farmers' dependence ES not yet adequately explored or completely understood. This study employs a sustainable livelihood framework to identify mechanism through which RLC affects ES,...
Conventional multiple input output (MIMO) detection algorithms face challenges related to computational complexity and limited performance when handling high-dimensional inputs complex channel conditions. In order enhance signal recovery accuracy in atmospheric turbulence channels for faster-than-Nyquist (FTN) optical wireless communication (OWC) systems, a deep learning (DL) based MIMO detector is proposed. By leveraging neural network (DNN), it becomes possible learn nonlinear mappings...
To mitigate inter-symbol interference (ISI) caused by Faster-than-Nyquist (FTN) technology in a multiple input output (MIMO) optical wireless communication (OWC) system, we propose an ISI cancellation algorithm that combines multi-head self-attention (MHSA), one-dimensional convolutional neural network (1D CNN), and bi-directional long short-term memory (Bi-LSTM). This hybrid extracts data features using 1D CNN captures sequential information with Bi-LSTM, while incorporating MHSA to...
The method of utilizing rain water has been well developed in foreign countries to realize the sustainable development recourse while is still at initial level China. When considering increasing shortage and urban flood, awareness water, as an inevitable trend, applied various engineering technologies. This article analyzed principle conventional road drainage system application artificial wetland technology, also proposed combine wetland, a complex system, utilize decrease flood pressure,...
Traditional multiple input output (MIMO) detection algorithms encounter challenges with computational complexity and performance limitations when dealing high-dimensional inputs complex channel conditions. To improve the precision of signal recovery in atmospheric turbulence channels for faster-than-Nyquist (FTN) optical wireless communication (OWC) systems, a deep learning (DL) based MIMO detector is proposed. By utilizing neural network (DNN), nonlinear mappings systems can be learned,...
