Emotions are an essential part of human physiological performance. Therefore, the study of emotion recognition is extremely relevant in both practical applications and theoretical research. Based on the electroencephalogram (EEG) data we collected, this paper explored the differences from five different characteristics among the coefficient of variation (CV) , power spectral density (PSD) , differential entropy (DE) , approximate entropy (AE) , and permutation entropy (PE) of three emotions at different rhythms, analyzed the activity of each brain region under different emotions. Finally, this paper also compares the classification accuracy of single features and combined features. The experimental results reveal that emotions are more strongly correlated with Beta and Gamma bands;temporal lobe regions are most active in emotion-related brain activity;and the accuracy of combined features is higher than the accuracy of single feature classification. The experiment conclusively demonstrates that effective feature extraction and selection have far-reaching implications for emotion recognition. © 2023 IEEE.

Automated visual inspection of on- and off-shorewind turbines using aerial robots provides several benefits, namely, a safe working environment by circumventing the need for workers to be suspended high above the ground, reduced inspection time, preventive maintenance, and access to hard-to-reach areas. A novel nonlinear model predictive control (NMPC) framework alongside a global wind turbine path planner is proposed to achieve distance-optimal coverage for wind turbine inspection. Unlike traditional MPC formulations, visual tracking NMPC (VT-NMPC) is designed to track an inspection surface, instead of a position and heading trajectory, thereby circumventing the need to provide an accurate predefined trajectory for the drone. An additional capability of the proposed VT-NMPC method is that by incorporating inspection requirements as visual tracking costs to minimize, it naturally achieves the inspection task successfully while respecting the physical constraints of the drone. Multiple simulation runs and real-world tests demonstrate the efficiency and efficacy of the proposed automated inspection framework, which outperforms the traditional MPC designs, by providing full coverage of the target wind turbine blades as well as its robustness to changing wind conditions. The implementation codes11https://***/open-airlab/VTNMPC-Autonomous-Wind-Turbine-Inspection are open-sourced. © 2023 IEEE.

Municipal solid waste incineration (municipal solid wastes incineration, MSWI) is a common method to reduce waste and produce energy. In the process of municipal solid waste incineration, furnace temperature is an important index to control and optimize the process of municipal solid waste incineration. However, due to the limitation of environment and instruments, it is difficult to accurately measure the furnace temperature online. This paper proposes a neural network based on Sparrow Search Algorithm (SSA) to optimize Elman, and designs a furnace temperature prediction model for urban solid waste incineration process, trying to obtain real-time and accurate measurement of furnace temperature. The structure and training method of the prediction model based on SSA-ELMAN network are introduced in detail, and the nonlinear relationship between furnace temperature and other process variables is established. Finally, a comparative experiment was carried out using the historical data of a waste incineration plant. The results show that the furnace temperature model established in this paper has the advantages of accuracy, generalization ability, stability and training efficiency. © 2023 IEEE.

Uncrewed aerial vehicles (UAVs) have gained significant attention due to their low cost and efficient deployment. Specifically, UAV-based communications hold promise to supplement the coverage limitations of terrestrial networks and achieve superior connectivity for the Internet of Things (IoT). Moreover, UAVs with visible light communication (VLC) capability do not interfere with existing radio frequency (RF) communication infrastructure, thereby providing flexible, high-throughput on-demand wireless communications. In this article, considering the limited battery capacity of UAVs, we aim to maximize the energy efficiency (EE) of a multi-UAV downlink VLC system for IoT. To this end, the system model with co-channel interference is first established, followed by the formulation of the joint spatial deployment and resource allocation problem. Besides, the original problem is decomposed into three subproblems, focusing on spatial deployment, subchannel assignment, and power allocation. By employing the block coordinate descent (BCD) method, the three subproblems are solved alternately. Moreover, simulation results demonstrate that the proposed method achieves superior improvements in EE compared to other baselines. In addition, the convergence and computational complexity of the proposed algorithm, as well as the impacts of key parameters on the overall system performance are also investigated. © 2014 IEEE.

In DC microgrids, current sharing and voltage regulation are two main objectives for real-time control, while the operation loss reduction is typically achieved by steady-state optimization. However, the ratio of current sharing is generally determined by the result of the centralized optimization in the classical hierarchical control framework of DC microgrids. Such an issue brings insufficient capability in respond to the changes of photovoltaic power and stored energy in the solar-powered energy systems. To handle this, this work proposes a distributed control scheme for single-bus DC microgrids. Under the proposed controller, the objectives of current sharing, bus voltage regulation and the total operation loss (converter loss and line loss) reduction can be guaranteed simultaneously. Moreover, the constraints on line currents and bus voltage are tackled as well. Finally, simulations verify the performance of the proposed control scheme. © 2024 Technical Committee on control Theory, Chinese Association of Automation.
