Federated learning (FL) has gained widespread attention for its privacy-preserving and collaborative capabilities. Due to significant statistical heterogeneity, traditional FL struggles generalize a shared model across diverse data domains. Personalized federated addresses this issue by dividing the into globally part locally private part, with local correcting representation biases introduced global model. Nevertheless, converged parameters more accurately capture domain-specific knowledge,...

Lack of trust has often been considered as a crucial barrier to the adoption electronic commerce. To address this problem, model is proposed in paper. Since uncertainty nature trust, it necessary for us take into account during modeling trust. Distinguished from other models, novel approach employed describe model, namely cloud-model. cloud-model quite new and still progress development, can not be applied directly, hence we have extend firstly. Then present an extended-cloud-model-based...

A sensorless displacement estimation method for an electrostatic film motor has been proposed in the previous work. Differently from existing built-in sensor systems motors, can estimate slider position by directly utilizing driving currents. Therefore, sensing be realized a simple hardware; it does not require additional hardware components. In its trade-off, performance of considerably affected structures and operation voltage waveforms. However, work only investigated sinusoidal-voltage...

The dechirp-receiving radar measures range by the frequency difference between target echo and reference signal. It can operate at a low sampling while transmitting wideband signal, which simplifies hardware. However, when detecting high-speed highly maneuvering targets, residual video phase (RVP), mismatch, modulation (FM) rate across range-Doppler unit (ARDU) problems occur after dechirp receiving, cause difficulties in integrating result severe performance loss. To solve these problems,...

Selective catalytic reduction (SCR) technology is the most widely used denitrification method in industry. However, calibration of its kinetic model very problematic due to large number parameters involved and nonlinear characteristics, especially for undesired reactions such as formation-decomposition ammonium nitrate (AN), sulfate (AS), bisulfate (ABS), etc. In this paper, synthetic gas test bench SCR system WD10 marine diesel engine burning high-sulfur fuel oil (HSFO) low-sulfur (LSFO)...

In a previous study, displacement self-sensing using driving current has been proposed for synchronous-type macroscale electrostatic motor under alternating (ac) operation; however, it cannot be used in practice due to its low noise immunity.
