Abstract: Aiming at the problem of slow speed in image matching,anti-interference difference and relatively poor ability to resist deformation,proposed a fast image matching method based on artificial fish swarm algorithm (AFSA). In the same test environment,Compared with the image matching method based on particle swarm optimization (PSO) algorithm and found,the method is superior to image matching method based on particle swarm optimization,in matching speed and noise resistance ability and deformation resistance ability has a marked improvement.

Abstract: Along with the rapid development of today's society, all sorts of wastes produced from human life and production are discharged into the natural environment, so that a certain impact has been exerted on air, soil, lakes, and oceans. The wastes discharged into the natural environment not only contain some toxic substances and various compounds difficult to degrade, but also are with the characteristics of strong acid, strong alkali, high temperature, and high salinity, so that the general microorganisms are hard to survive in this environment. However, there are some extreme microorganisms to gradually fit the environment in the process of evolution, and the microorganisms include alkalophilic bacteria, basophilic bacteria, halophilic bacteria, etc. Halophilic bacteria grow mainly in sea and salt lake, and also have unique physiological features, while the application of high-salinity microbes to the disposal of salt-contained wastewater is of a broad prospect and an important social value. In this paper, the isolation and identification of microorganism in a high-salinity environment and their application to the disposal of salt-contained wastewater are mainly analyzed.

Abstract: This paper describes a new method for prediction of the Chapman–Jouguet detonation parameters of CaHbNcOdLieMnf explosives for mixture of some of low temperature explosion explosives at 0 = 1000 kg/m3. Explosion temperatures of water-gel explosives and explosive formulations are predicted using thermochemistry information. The methodology assumes that the heat of detonation of an explosive compound of products composition H2O–CO2–CO–Li2O–MnO2–Mn2O3 can be approximated as the difference between the heats of formation of the detonation products and that of the explosive, divided by the formula weight of the explosive. For the calculations in which the first set of decomposition products is assumed, predicted temperatures of explosion of water-gel explosives with the product H2O in the gas phase have a deviation of 153.29 K from results with the product H2O in the liquid state. Lithium and manganese oxides have been prepared by the explosion of water-gel explosives of the metal nitrates, M (NO3) x (M = Li, Mn) as oxidizers and glycol as fuels, at relative low temperature. We have also used the Dulong-Petit’s values of the specific heat for liquid phase H2O. Lithium manganese oxide powders with chrysanthemum-like morphology secondary particles, but with smaller primary particles of diameters from 5 to 30 nm and a variety of morphologies were found. The oxides produced by this cheap method affirmed the validity of explosion synthesis of nano-size materials for lithium ion batteries.
