In order to monitor the water quality in real time, all monitoring points should be covered by Unmanned Surface Vessel (USV). This paper takes the USV as the research object and proposes an improved genetic algorithm to solve the complete coverage path planning (CCPP) problem to ensure that the USV can cover all monitoring points, and minimize the path length, the rate of repeat grid and running time of the algorithm. The feasibility of this solution model is verified by simulation on the platform of Visual Studio.

Three dimensional point cloud map in the anthropometry has attracted intensive attention due to the availability of fast and accurate laser scan devices. Inevitably, there is a data deviation between 3D measurement and manual tests. To address this problem, shoulder width and neck girth are accurately determined from 3D point cloud, the two-scale fractal is used for 3D point cloud simplification, and young female samples are used in our experiment to show the accuracy.

In this study, the thermo-physiological wear comfort is mainly characterized by the thermal and water vapor resistance performance of the woven fabrics used as sportswear for outdoor activities. The commonly used twill woven fabric with different thicknesses, weight, and density are selected for the experimental analysis, and it finds that fabric weight and thickness have crucial effects on the thermal resistance, and the water vapor resistance depends linearly on density and thickness. The present study gives an optimal design of sportswear for outdoor activities with low thermal and water vapor resistance.

Under the urgent demand of effective energy-storage and thermal-regulatory textile fabrics, the air-conditioning tussah silk as a new arrival is endowed with this excellent property by coupling with the phase change material of capric acid-stearic acid eutectic mixture. In addition, the facile pad-dry-cure technique used with the assistance of ultrasonic waves efficiently avoided the problems of the sophisticated process and low efficiency in traditional post-finishing methods with phase change microcapsules. With optimal preparation conditions, the resultant tussah silk exhibited a superior thermal reliability and thermoregulatory character along with a phase enthalpy of 31.80 J g −1 at a phase change temperature of 24.01 °C. Meanwhile, the tested air permeability, mechanical properties and washing fastness showed its favorable thermal and wear comfort. Benefitting from these admirable merits, this air-conditioning tussah silk with tunable heat storage and release performance could automatically respond to external temperature stimuli, finally contributing to practical application in intelligent protective garments. The intelligent bidirectional temperature-adjusting property corresponding to the efficient management of human skin temperature is beneficial for constructing a comfortable microclimate for the human body. In brief, our study provides a novel heat-storage and temperature-regulating textile with tussah silk as well as unique natural advantages by means of a simple preparation method.
