OBJECTIVE To construct a life-sized eye model using the three-dimensional (3D) printing technology for fundus viewing study of the viewing system. METHODS We devised our schematic model eye based on Navarro's eye and redesigned some parameters because of the change of the corneal material and the implantation of intraocular lenses (IOLs). Optical(More)
—The Low-rate Denial of Service (LDoS) attack is a new type of DoS (Denial of Service) attack, which produces the similar harmful effect as the DoS attack. It is more difficult for existing DoS detection methods to detect the LDoS attacks because of their distinct characteristics, at the same time the accuracy of the current detection methods for the LDoS(More)
OBJECTIVES We assess the prevalence and pathogenic stage of skeletal fluorosis among children and adolescents residing in a severe coal-burning endemic fluorosis area of southwest China. METHODS We used a cross-sectional design. A total of 1,616 students aged between 7 and 16 years in Zhijin County, Guizhou, China in late 2004 were selected via a cluster(More)
In this paper the key indicators of sports tourism competitiveness were selected through the factor analysis method, by using the factor analysis method in Spss22.0 software, all kinds of sports tourism data in each city and county of Hainan were analyzed according to the factor analysis method and the sports tourism competitiveness of each city and county(More)
In this paper, firstly, the airport stochastic factors are analyzed, and the airport capacity is classified. When the airport capacity decreases, a formula which is used to compute the landing time of aircraft is given according to the rules of dynamic change of landing aircrafts' queue length. Secondly, the rules of dynamic change of departing aircrafts'(More)
—The Low-rate Denial of Service (LDoS) attacks reduce network services capabilities by periodically sending high intensity pulse data flows. For the hidden performance of LDoS attacks, it is more difficult for traditional DoS detection methods to detect. At the same time the accuracy of the current detection methods for the LDoS attacks is relatively low.(More)
:In order to realize spatial differentiation law of peanut quality in China by quantitative analysis method based on GIS technology, a spatial analysis model for peanut quality was established based on 9 ecological factors influencing peanut quality (light, temperature, water and soil, etc). The results showed that it can be achieved in the analysis of(More)
Integration of sensors, embedded operating systems, wireless networking technology, wireless sensor networks, is a new information gathering and processing technologies, in environmental monitoring has a very good application and advantages. This paper introduced a method model based on ZigBee-technology. Depending on specific situation in environment,(More)
