Nanocarbon modification of membranes for enhanced water desalination and water treatment [PDF]

, 2020
Water scarcity is foreseen to be one of the great global issues in the coming decades. The challenges are not only in providing water supply to cope with the growing public demand, but recovering clean water to natural resources. Clean water supply, from

Improving sweeping gas membrane distillation applicability and specific thermal energy consumption [PDF]

, 2018
The compatibility of sweeping gas membrane distillation (SGMD) with simple solar thermal devices, and ambient air and pressure operation make it attractive for desalination in off-grid remote communities. Since simplicity of operation is critical for

Sim-Geometry Modal Decomposition (SGMD)-Based Optimization Strategy for Hybrid Battery and Supercapacitor Energy Storage Frequency Regulation

Symmetry
This study examines the issue of wind power smoothing in renewable-energy-grid integration scenarios. Under the “dual-carbon” policy initiative, large-scale renewable energy integration (particularly wind power) has become a global focus. However, the intermittency and uncertainty of wind power output exacerbate grid power fluctuations, posing ...

基于SE-improved SGMD的混合储能容量优化配置方法研究

Gaoya dianqi
采用混合储能系统平抑风电输出功率波动可有效解决风电并网问题，而不同功率分配方法对混合储能优化配置结果影响大，为此提出一种基于样本熵改进的辛几何模态分解方法（sample entropy-improved symplectic geometric mode decomposition，SE-improved SGMD）的混合储能系统功率分配策略。首先，采用SGMD对不平衡功率进行分解，获取一系列辛几何分量SGC（symplectic geometry component）；然后 ...

基于ISGMD⁃RPT的滚动轴承故障诊断方法

Zhendong Ceshi yu Zhenduan
针对传统辛几何模态分解（symplectic geometry mode decomposition， 简称SGMD）方法因嵌入维数选择依靠经验公式，导致出现信号模态混叠和过度分解的问题，提出了一种改进的辛几何模态分解（improved symplectic geometry mode decomposition， 简称ISGMD）方法。首先，通过计算原始信号的功率谱密度得到最大主峰的频率并设定嵌入维数区间，根据峭度准则筛选分解后的辛几何分量（symplectic geometry component，
