Summary: A novel open-circuit fault diagnosis method for the four-wire T-type three-level rectifier (four-wire 3LT(2)R) is proposed in this article, considering power factor regulation. The diagnostic method is designed based on the deep analysis of the relationship between the power factor and the working interval of the transistor. The faults with different features related to the size of working intervals are detected using the zero current in each phase current, and the fault transistor is located according to the polarities of the currents and the modulated voltages, without additional sensors.

Summary: In this study, a time-saving approach for measuring the open-circuit voltage (OCV) of a battery is proposed. By using a simplified first-order RC circuit model, the OCV at each state of charge (SOC) can be computed without the need for complete voltage relaxation information. Experimental results demonstrate that this approach significantly reduces the measurement time (usually less than 6 minutes) while maintaining high accuracy (usually less than 3 mV) compared to traditional methods.

Summary: This paper discusses the feasibility of indirectly measuring the moisture content of similar material models using three-dimensional laser scanning reflection intensity. The results show that the laser reflection intensity is sensitive to factors such as moisture content, incidence angle, and distance. The established correction models can weaken the influence of these factors, and the method's accuracy can meet the requirements for monitoring the moisture content of similar material models under specific conditions.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
