| 2 | A mutli-scale spatial-temporal convolutional neural network with contrastive learning for motor imagery EEG classification显示文摘Motor imagery(MI)based Brain-computer interfaces(BCIs)have a wide range of applications in the stroke rehabilitation field.However,due to the low signal-to-noise ratio and high cross-subject variation of the electroencephalogram(EEG)signals generated by motor imagery,the classification performance of the existing methods still needs to be improved to meet the need of real practice.To overcome this problem,we propose a multi-scale spatial-temporal convolutional neural network called MSCNet.We introduce the contrastive learning into a multi-temporal convolution scale backbone to further improve the robustness and discrimination of embedding vectors.Experimental results of binary classification show that MSCNet outperforms the state-of-theart methods,achieving accuracy improvement of 6.04%,3.98%,and 8.15%on BCIC IV 2a,SMR-BCI,and OpenBMI datasets in subject-dependent manner,respectively.The results show that the contrastive learning method can significantly improve the classification accuracy of motor imagery EEG signals,which provides an important reference for the design of motor imagery classification algorithms. | Ruoqi Zhao Yuwen Wang Xiangxin Cheng Wanlin Zhu Xia Meng Haijun Niu Jian Cheng Tao Liu | 2023 | Medicine in Novel Technology and Devices2023，，1： | 0 |
| 3 | Can the ASHRAE Standard 169 zoning method be applied to country-level energy-efficient building design in China?显示文摘In current building thermal climate design zones of China,the zoning indicators only include temperature elements without considering the regional difference of air humidity.Therefore,building thermal design strategies in continental climate zone with low relative humidity and marine climate zone with high relative humidity cannot be distinguished by the current building thermal zoning standards.ASHRAE Standard 169 proposes dual definitions for moisture and thermal climate zones,and this method can be extended to the world,including the so-called“China Climate Zones Map”.However,the moisture climate zoning criterion is unsuitable for China’s climate characteristics after climate analysis and building performance evaluation.In present work,a novel building moisture climate zoning method is proposed.The bioclimatic chart was utilized for extracting the outline of building climate through the Gaussian KDE method.Hence,the building moisture climate was classified,the zoning indicator was obtained,and a country-level climate zones map for China was established.The results indicated that the global information matrix served as a helpful guide and reference for planning at the national level.Annual precipitation could be used as a zoning indicator to accurately reflect the regional differences of building moisture climate in China.The approach can provide new thoughts for improving the climate zoning system in current energy-efficient building design standards of China to assist the ultra-low energy consumption target. | Shangyu Wang Liu Yang Xiangxin Meng Kailin Lyu Qimeng Cao Yan Liu | 2023 | Building Simulation2023，16，7： | 0 |
