Parameter optimization method for light field 3D display.

A parameter optimization method for light field three-dimensional (3D) display is proposed to improve the performance of integral imaging (InI) and super multi-view (SMV) display. The parameters of light field display are divided into system parameters and display parameters. The multi-objective genetic algorithm is used to optimize the system parameters so that the display parameters can reach the target values.

Effect of moisture on microwave ignition of bituminous coal.

The interaction between water and microwave is of vital importance to reveal the microwave ignition mechanism of water-bearing coal. This study used two group of bituminous coal after drying and water saturation treatment, for experimental testing and contrastive analysis. During the experiment, permeability of coal samples was obtained based on nuclear magnetic resonance(NMR) test, then different power of microwaves were applied to coal samples, and the occurrence of hot spots within coal samples was regarded as a sign of microwave ignition.

Molecular understanding of charge effect on desalination performance in lamellar MoS membranes.

Due to its advantages of superior oxidation resistance, excellent chemical stability and non-toxicity, molybdenum disulfide (MoS) has shown prospects in seawater desalination applications. In this manuscript, molecular dynamics (MD) simulation has been employed to explore the effect of charge distribution in MoS nanosheets on the desalination performance of the lamellar MoS membrane. It is found that the model considering the atomic charge better describes the transport behavior of salt solution in the membranes.

Mechanistic Study of a Microwave Field-Controlled Static Crushing Agent for Efficient Rock Breaking.

The long reaction time and uncontrollable reaction process of the swelling agent in the process of rock breaking by static crushing agent lead to unsatisfactory efficiency and effect of rock breaking. This paper uses physical experiments to compare and analyze the changes in temperature and pressure of the hydration reaction under different microwave conditions; utilizes microscopic analysis of the hydration reaction products under each condition, combined with numerical calculations to elucidate the mechanism of the effect of microwave field on the hydration reaction of the expansion agent; and proposes a microwave field-controlled static crushing agent rock-breaking method. The study reached the following main conclusions: (1) microwave heating is better than conventional heating in terms of heating rate, peak temperature, and peak pressure; (2) using static crushing agent rock breaking is preferable to use a low-power microwave field to control the reaction process, and to ensure that the initial temperature is not higher than the local water boiling point; (3) microwave heating to promote the reaction mechanism lies in its deep heating of the system, faster heating rate, and higher energy utilization, and is more conducive to hydration expansion reaction; (4) selective heating of microwaves can enhance the hydration reaction of calcium oxide and inhibit the production of hydrated tricalcium silicate, making the reaction more complete, while microwave heating will also improve the microstructure of hydration products.

Effects of Microwave Heating Paths on Pores and Cracks in Bituminous Coal.

To follow the effect of the microwave heating path on the structure of coal, eight 50 mm diameter, 30 mm long dry coal cores from the same coal seam with similar pore structure characteristics were microwave-treated using 4 pathways. The spectrum, pore-volume, temperature, mass, and visual changes of coal samples were analyzed before and after microwave heating. The microwave heating path affected the macropores and microcracks and the crack development mode.
