This paper presents an optimal scheduling model for household appliances in smart homes, focusing on residential demand response (DR) to reduce consumer electricity costs and enhance power system stability. The model integrates considerations of electricity costs, incentives, and consumer inconvenience under time-of-use (TOU) pricing. It explores how the inconvenience weighting factor impacts total costs and analyzes the effect of incentives on optimization outcomes. Simulation results demonstrate the model's efficacy, indicating a potential reduction of 34.71% in consumer costs. Additionally, findings suggest that increasing inconvenience raises costs, impacting consumer participation in DR programs. The study also shows that incentives effectively shift loads and lower energy expenses, providing new insights into residential DR applications. © 2024 IEEE.

To address the complexities and incompleteness of manual electroencephalogram (EEG) feature extraction, this paper proposes a fatigue detection method based on a multi-feature fusion convolutional neural network with an attention mechanism. This approach aims to achieve more accurate and comprehensive fatigue detection and analysis. The EEG data from the SEED-VIG dataset is denoised and segmented, with 4D features extracted and generated. These features are then input into spatial, frequency, and temporal attention modules for fusion, resulting in the output of final fatigue detection results. Testing on SEED-VIG samples demonstrates that the proposed algorithm achieves a correct recognition rate of 82.21%, thus validating its effectiveness. © 2024 SPIE.

This paper presents a radar target recognition framework based on ultra-wideband (UWB) electromagnetic scattering features extracted from the fused full band. Firstly, multiple frequency subbands are fused to obtain UWB High Range Resolution Profile (HRRP) and parametric features based on geometrical theory of diffraction (GTD) model of the target. Secondly, the UWB HRRP are fused with UWB parametric features by proposed target recognition framework. Thirdly, target recognition is accomplished with the proposed framework in which the concatenated features are set as the input of an existing network. Simulations results show the validity of our method and reveal that it can achieve better recognition accuracy. © 2023 Applied Computational Electromagnetics Society (ACES).

The recommender systems on online platforms assist users in finding personalized information, yet this also leads to the issue of limited diversity, potentially giving rise to societal issues such as filter bubbles. Despite significant progress in diversified recommendation algorithms, they have not been extensively experimented with and evaluated for effectiveness in large-scale, full-stage industrial recommender systems. Specifically, industrial recommenders usually consist of three stages of matching, ranking, and re-ranking, in which specific characteristics lead to critical challenges for promoting both recommendation diversity and user engagement. First, user interests are partially observed due to only relevance maximization. Second, item-side feature-aware bias causes imbalanced recommendations. Last, the impact of diversity perception on user engagement stresses the necessity of explicit diversity modeling. To address these challenges in industrial systems, in this work, we deploy several existing diversified algorithms in a real-world short-video platform, including exploration-exploitation, feature-aware debiasing, and diversity optimization. We conduct large-scale online A/B testing for evaluation via online metrics of user engagement and recommendation diversity. Performance improvement across full stages demonstrates the effectiveness of these simple solutions. From comparing performance across different stages and algorithms, we identify that the ranking stage is the most suitable for real-world deployment, and the combination of debiasing and diversity optimization is a promising direction in terms of diversified recommendations. This work provides experiential guidance for the large-scale deployment of diversified algorithms and the construction of a more inclusive platform on the Web. © 2024 Owner/Author.

A miniaturized dual-band microstrip array antenna is proposed. Firstly, a microstrip antenna with dual frequency is designed by using slot to reduce the size, and a dual frequency microstrip antenna is formed by coupling series feed between two rectangular patches. The two operating frequencies can be flexibly adjusted by adjusting the size of two rectangular patches or the slotted length. A miniaturized microstrip antenna with suppressed sidelobe is formed by an array antenna composed of one minute and four unequal power divider. The antenna works in both the 32.3GHz-32.9GHz and 34.5GHz-35.9GHz bands. This dual-frequency antenna has a simple structure, stable performance, and has a certain application value. © 2024 IEEE.
