With the enhancement of health awareness and the development of artificial intelligent technology, healthcare recommender systems (HRS) play an increasingly important role in individual health management. Meanwhile, the widespread usage of large models has significantly improved the efficiency and accuracy in the analysis and utilization of medical data. In this paper, we comprehensively summarize the basic types of recommender systems as well as the new trends in utilizing large models. Then we introduce the recommendation applications in healthcare areas from six aspects, i.e., disease risk prediction, medication recommendation, medical resource recommendation, mental health support, health life management, and health education. At last, we explore some current issues and challenges within HRS, as well as the development of potential solutions and directions in the future.

Model predictive control (MPC) methods are widely used in permanent magnet synchronous motor (PMSM);however, How to minimize the impact of system delay and motor parameter perturbation on the operation of PMSM is the key to constrain the MPC. To address the problem of current disturbance caused by system delay and motor parameter perturbation, we will propose a series of sliding modes to suppress current disturbances caused by above reasons. Besides, The PMSM model is used to analyse the causes of system delay. Then, the current disturbance caused by parameter perturbation is introduced into the adaptive sliding mode control algorithm for suppression, and the relevant theoretical proof is given. Finally, the effectiveness of the overall scheme is verified through simulations. © 2023 IEEE.

IEEE 802.11 Wireless Local Area Network (WLAN) is a popular way for mobile devices to access the Internet. Operators and service providers often increase the density of wireless access points in order to provide users with better connections and user experience. As a result, WLAN users find themselves covered by multiple access points. In traditional wireless multi-hotspot networks most user terminals choose the access point with the strongest signal without considering the existing load on that access point, leading to severe congestion and load imbalance problems. This paper proposes an improved NSGA-II-based load balancing strategy for wireless multi-hotspot networks, which determines which hotspot should be associated with each user terminal by taking into account the current access point load, the received signal strength and the throughput size of the user terminal. The simulation results show that compared with the traditional strongest signal First (SSF) strategy, the proposed load balancing strategy can improve the network throughput by more than 30%. © 2022 IEEE.

Regarded as the most important object of marine environmental monitoring, wave condition especially the height, period measurement technology has comprehensively involved various means during the deepening of wave research. Among many wave measuring methods, wave measuring buoy is recognized as the most direct and accurate equipment. Acceleration integration and turbine flow meter constitute the traditional mainstream of wave testing. GPS and MEMS sensors have been developed to measure waves in recent years. Because buoy is a wave measuring equipment that directly contacts the sea surface, its measuring accuracy is higher than that of other wave measuring methods, so it is also considered by foreign countries as the most direct and accurate wave measuring equipment. In this paper, GPS and MEMS sensing technology are mainly used to analyze the wave height and period measurement. At the same time, the main development process of the wave height gauge is introduced extensively. Finally, the accuracy and repeatability of the wave height meter are tested by means of walking crane, certificated meter ruler and stopwatch. The test results show that it can meet the relevant standards of wave measurement and monitoring. On this basis, the sensor is tested in the South China Sea, and the reliability of the instrument is further verified. In one word, the paper can provide theoretical basis and technical support for the research and development of wave measurement equipment and promote the practical application in the field of wave condition monitoring. © 2022 IEEE.

The liner type self-lubricating joint bearings are simple in structure and have large load bearing and impact resistance, which are widely used in aerospace, automotive, construction machinery and many other fields. The accurate assessment of their health status can provide a decision basis for the repair and maintenance of the equipment, which can effectively reduce the safety accidents and economic losses. Considering multiple features, such as the friction torque, wear amount and friction temperature and so on, a VMD-AM-LSTM-based method for health condition assessment of liner-type self-lubricating joint bearings is proposed, which is able to predict the degradation tendency of the liner type self-lubricating joint bearing more accurately in order to grasp its health condition. Firstly, a set of fatigue wear tests of liner-type self-lubricating joint bearings under multiple working conditions is carried out by using a comprehensive evaluation testing machine for joint bearings to collect signals such as friction torque, wear and temperature during the degradation of the bearings. Secondly, the VMD method is used to extract features from the collected signals in order to obtain the feature components that can characterize the bearing degradation trend. Then the feature components are normalized and input to the VMD-AM-LSTM model for training and testing. Finally, the Bayesian optimization method is used to optimize the hyperparameters to further improve the prediction accuracy of the model. A series of comparative experimental results show that the proposed method has higher prediction accuracy for the health condition of liner type self-lubricating joint bearings under different working conditions. © 2025 IEEE.
