Novel application of graphene combined with light emitting materials has been proposed recently due to the plasmonic effects of graphene. Here, we report our investigations on the structural and optical properties of two graphene/ZnO hybrid structures that fabricated based on different ZnO supports. Plasmon-enhanced ultraviolet photoluminescence has been observed from both samples. The combined Raman and photoluminescence studies suggest a strong interaction between ZnO and graphene, which is affected by the surface structures of ZnO. Our results develop insights about the influence of ZnO supports on the PL enhancement and interfacial coupling in graphene/ZnO hybrid structures, which provides a reference for the design and fabrication of optoelectronic devices with high efficiency.

Weapon target assignment problem is most critical in modern warfare command decision of a problem for the weapon system and a relatively small number of targets assignment problem, you can use the Hungarian algorithm. Hungarian algorithm can solve the assignment problem, but under normal circumstances, weapon target assignment problem does not have the form of a mathematical model of assignment problem, through dummy weapon system or target method, the weapon target assignment problem is transformed into a standard assignment problem, and then solved by the Hungarian algorithm.

Coal blending technology is commonly used in coal-fired thermal power plant in recent years to ease cost pressures. But thermal power plants still use empirical formula to determine the economic fineness of pulverized coal. This approach cannot change economic fineness of pulverized coal based on the proportion of blending coal timely and accurately, resulting in increasing carbon content of fly-ash and reduced combustion efficiency of boiler. In this paper, a new method for determining pulverized coal economic fineness is proposed. Dry ash-free basis volatile, coal uniformity index, ignition temperature, proportion of blending coal are considered as parameters. According to the relationship between these parameters, the best coal fineness can be obtained in real-time. Influences of coal blending technology are reduced greatly and the accuracy of the economic fineness is improved.

Deep brain stimulation (DBS) is increasingly used in clinical treatment for various neurological disorders, particularly for movement disorders such as Parkinsons disease. The more the accuracy of locating the cerebral target of these diseases is, the more cure effect is, the accuracy of locating the cerebral target depends on the all surgery system. Although there have many surgery systems, for more accuracy of those locating target based on CT images, it need to develop a new kind of robotic surgery system. Some requirements of this robotic system are present in this paper, such as the movement degrees of freedom and its dimension error.

Activated carbon filter is often used as the pretreatment process of nanofiltration or reverse osmosis membrane system, especially when the content of organics and free chlorine in influent water is high. However, a lot of microorganisms often rapidly reproduce in the activated carbon filter after continuous operation, resulting in a large number of bacteria in the effluent. So when the activated carbon filter was used as pretreatment of membrane systems, membrane fouling caused by biological contamination often occurred. The objective of this paper was to discuss how to effectively control the activated carbon biological contamination. Three different control methods—water backwashing, hot alkali treatment and ultrasound treatment were compared. Results showed that ultrasound treatment was the most effective. A relatively high removal efficiency of biomass (above 90%) was obtained when 40 kHz ultrasound was applied at 90 W for 20 min. Bacterial count in the effluent can be decreased from 3.90×104CFU•mL-1 to 8.5×103CFU•mL-1. After 3 days of continuous operation, bacteria count increased from 8.5×103CFU•mL-1 to 4.06×104CFU•mL-1. After ultrasound treatment, the removal efficiency of CODCr increased from -386.3% to 73.8%.

Value at Risk ( ) is a method using statistical knowledge to measure financial risks, and its calculating core is to estimate or predicate fluctuation of the financial assets price. In recent years, the main method of estimating and predicating fluctuation of the financial assets price is the GARCH model. So to determine a reasonable GARCH model becomes the crux of calculating. In this paper, we proposed using empirical likelihood method to estimate , and we also proved that the empirical likelihood method is more effective and more concise than other current methods by simulation analysis.
