Abstract

In order to improve the recovery and utilization of hot water energy in gas water heater pipes, a self-powered solution is proposed in this study. The proposed solution focuses on improving energy collection efficiency by increasing the heat transfer coefficient of the water flow and tracking the maximum output power of the temperature plate. The design of heat transfer structure, power characteristics of temperature plate and circuit conversion are analyzed. In order to verify the feasibility of the proposed solution, a test device was constructed for physical testing and verification. The experimental results demonstrate the successful implementation of the self-powered gas water heater. The special structure and perturbation method used enable the experimental device to achieve the maximum power output, and the experimental device can continuously provide 300mW output power. This research contributes to the development of energy -efficient and self-powered gas water heater solutions, offering potential benefits for energy saving and sustainable use in the residential sector.

Subjects
convergence, differential evolution algorithm, electronic wristbands, fitness function, LORA communication, Engineering (General). Civil engineering (General), TA1-2040
Abstract

In this paper, an improved differential evolution algorithm is proposed to improve the positioning accuracy of electronic wristband system. The wristband system is composed of STM32F103 microcontroller, Beidou positioning module, LORA communication module and so on. In the traditional differential evolution algorithm, premature convergence to local optimal will reduce the accuracy of the algorithm. To solve this problem, the method introduces the distance information between known and unknown points and between all unknown points in the fitness function and overall initialization. This reduces the premature convergence of the algorithm and improves the optimization ability of the algorithm. Experimental results using the CICDDoS2019 dataset show that the localization accuracy of the proposed algorithm is improved by 7.6% compared with traditional differential evolution. The method also has good stability. This provides an effective way to improve the positioning accuracy of the wristband, which can be used for applications such as patient monitoring.

Abstract

Metal-organic framework (MOF)-based mixed matrix membranes (MMMs) have attracted significant attentions for their distinguished characteristics in pervaporation such as enhanced selectivity, increased permeability and improved mechanical strength through the synergistic integration of polymeric matrices and inorganic fillers. Although many publications have emerged in recent years focusing on MOF-based MMMs, this review specifically emphasizes the improvement of MOF-based pervaporation membranes through the design of dimension of fillers and microstructure. The challenges encountered in MOF-based MMMs for pervaporation and the essential requirements for practical separation applications are addressed. A brief summary of strategies is provided for designing MOF-based MMMs with desired microstructure, macrostructure and multicomponent characteristics by using MOFs as fillers. The latest progresses in novel MOF-based MMMs with specific compositions, controllable pore structure and improved compatibility for recovery of organics are also displayed. The broad application prospects of MOF-based MMMs in pervaporation are introduced, including recovery of ethyl alcohol, butanol and other organics. Moreover, the challenges faced in the practical application of MOF-based MMMs for recovery of organics are presented and the promising future directions are outlined.
