The Research on Clustering Algorithm Based on Wax Matching
Zhang Jianyan,Zheng Kun,Li Tianliang 보안공학연구지원센터 2015 International Journal of Signal Processing, Image Vol.8 No.12
The traditional clustering algorithms need some prior knowledge to determine the initial parameters, and the selection of initial parameters usually will produce great influence on the result of clustering. In order to achieve this purpose, we put forward a new clustering algorithm based on "idea", through optimizing the given data and mathematical model between the adaptive data to model the best match. This algorithm combined with an "idea" algorithm to learn the hybrid model because of the gaussian mixture model can be thought of as a distribution of soft clustering method. This clustering algorithm can overcome the shortcomings of k-means algorithm. Experimental result shows that the algorithm has better clustering effect.

Improvement of comprehensive performance of compound green soil in sponge city
Lei Zhang,Zhicheng Li,Tianliang Yang,Ping Yang 대한환경공학회 2021 Environmental Engineering Research Vol.26 No.5
Large-scale constructions of urbanization increase the impervious areas of city, leading to the urban hydrological effects such as urban waterlogging and rainwater runoff pollution. To this end, China proposed to adopt the measure to build sponge cities. However, the existing green soil cannot meet the comprehensive needs of sponge city. In order to quickly evaluate the comprehensive performance of the soil in sponge city, a comprehensive evaluation criterion was designed, which is related to the characteristics of greening soil permeability, porosity, pH, salinity and fertility. Based on the criterion, a new type of composite green soil was obtained with the silt soil: medium sand: sawdust ratio of 72.5%: 20%: 7.5%. Finally, compared with the existing soil, the new green soil not only meets the comprehensive performance requirements of the green soil’s fertility, pH, permeability and other factors, but also has higher permeability and water retention. It was proved that the new green soil has apparent advantages in the control of rainwater.

The Analysis of Climate Change in Haiyan County
( Wenzheng Yu ),( Hanxiaoya Zhang ),( Tianliang Chen ),( Jing Liu ),( Yanbo Shen ) 한국인터넷정보학회 2020 KSII Transactions on Internet and Information Syst Vol.14 No.10
In this paper, the climate change in Haiyan County in recent decades was analyzed in detail with the methods of moving average, Mann-Kendall non-parametric mutation test and wavelet analysis. According to the variation trend of meteorological factors such as temperature, relative humidity, wind speed, pan evaporation and precipitation in recent decades, the climate of Haiyan County has a tendency of drought, which is becoming more and more serious. From the results of the analysis, the sunshine hours and the air temperature in Haiyan County have an obvious upward trend. The average surface temperature has increased by 2.75 ℃ from 1976, and its largest increase occurred in the late 1970s and 1980s. At this stage, the average surface temperature increased by 1.37 ℃. The relative humidity has a decreasing trend that has decreased by 2.75%. From 1976 to the present, there are two quasi-3a cycles and one quasi-6a cycle. The precipitation and evaporation showed the opposite change trend, in which the trend of precipitation fluctuated upward, while the trend of evaporation showed a fluctuating downward tendency, which led to the serious loss of water in the feeding area. The wind direction in Haiyan County are mainly from west to east, and its wind speed has a trend of slight increase.

Cellular prion protein (PrPC) is ubiquitously expressed in the cytomembrane of a considerable number of eukaryotic cells. Although several studies have investigated the functions of PrPC in cell proliferation, cell apoptosis, and tumorigenesis of mammals, the correlated functions of chicken PrPC (chPrPC) remain unknown. In this study, stable chPrPC-downregulated Marek’s disease (MD) virus-transformed avian T cells (MSB1-SiRNA-3) were established by introducing short interfering RNA (SiRNA) targeting chicken prion protein genes. We found that downregulation of chPrPC inhibits proliferation, invasion, and migration, and induces G1 cell cycle phase arrest and apoptosis of MSB1-SiRNA-3 cells compared with Marek’s disease virus-transformed avian T cells (MSB1) and negative control cells. To the best of our knowledge, the present study provides the first evidence supporting the positive correlation between the expression level of chPrPC and the proliferation, migration, and invasion ability of MSB1 cells, but appears to protect MSB1 cells from apoptosis, which suggests it functions in the formation and development of MD tumors. This evidence may contribute to future research into the specific molecular mechanisms of chPrPC in the formation and development of MD tumors.
