Abstract: Internet traffic classification is an area of current research interest. The failure of port and payload based classification motivates researchers to head towards a machine learning (ML) approach. However, training and testing dataset validation has not been formally addressed. This paper discusses the problem of ML dataset validation and highlights three training issues to be considered in ML classification. The first issue is based on different network characteristics being training and testing datasets which are collected from two different networks. The second issue considers training dataset classes whose real online traffic classes are not presented. The third issue is the geographic place where the network traffic is captured. Real Internet traffic datasets collected from a campus network are used to study the traffic features and classification accuracy for each validation training issue. The experimental results demonstrate that there are differences in some traffic features such as inter-arrival time when training and testing data were collected from different networks. Furthermore, the experiment of the second issue shows that the online classifier achieved the highest accuracy (92.22%) when the ML classifier was trained by dataset classes which have the same ratio of the real online traffic. For the geographic capturing level, the results indicate that there is a difference in the traffic statistical features when the capturing level is different.

Abstract: In the cluster analysis, a wide range of methods dividing data into pairs of discrete clusters are considered. In this type of classification, there is a certain boundary among existing clusters so that one sample either belongs to a cluster certainly or not. The present paper analyzes data by using fuzzy clustering method. In so doing, 190 sediment samples were collected from a region located at North East of Birjand City and sent to the laboratory. The samples were analyzed for 51 elements. With regard to the lithology and geology conditions of the region, 4 to 10 clusters were selected experimentally and finally 5 clusters were selected as the optimal cluster number in which there was the minimum negative deposit anomaly. Then center of clusters was calculated. Anomalies in the region can be obtained by subtracting the resulted matrix from matrix of primary data. Also by determining the optimal cluster number with respect to the region lithology conditions and finally calculating anomaly existing in the regions, promising areas for more explorations of Ba and Ni elements were identified which show a proper correlation with geology conditions of the regions and lithology units. Soil permeability is not a function of the impact of these elements and they do not have a significant effect on the soil permeability, and the relative percentage of clay and silt has a descending trend by depth increase.

Abstract: Undesirable effect of erosion may not be significant in short time, but it will be clear on long time. Erosion and soil losse. are the main concerns decrease soil fertility and yield production, deposition  materials in waterways, irrigation channels and rivers, declining dam capacity, flooding and  environmental pollution and closing roads. The Saqqez catchment area is about 22,313 hectares. This watershed is one of Chehel cheshmeh mountainous basins that is located in the Saqqez county. The Cheraghvais dam are established on its main branches that estimated amount of soil erosion and sedimentation of behind the dam is necessary. Hence EPM model have been used using In order to prepare the first series of data, IRS satellite data, Landsat ETM⁺, basic maps, the Arial photos and GIS. Required layers information including geology, topography , pedology, land cover maps and runoff data , the current state of erosion, river erosion status using existing maps, satellite images, weather data stations, hydrometery and field operations were taken then into GIS environment. The formation of databases and the weighting of each of the map layers based on EPM model erosion and sedimentation maps were extracted according to the hydrologic units. The results which are presented as maps and erosion statistics, not only identify hazardous erosive areas, but also open a new horizon in the field of watershed management and sediment control by having a special outlook towards executive priorities.

Abstract: Virtual reality technology+journalism collided with a new spark, which gave birth to the inevitable product of technological innovation in media industry-virtual reality news. Through the comparative analysis of the types, advantages and disadvantages, development prospects and difficulties of virtual reality news, this paper holds that virtual reality news will definitely break through the technical limitations in the near future and realize the real-time, immersion and interactive dissemination of information.

Abstract: The levels of trace metals in the tissues of C. gariepinus from Orashi River, Niger Delta, Nigeria were investigated in order to ascertain the public health implication of consuming this edible species. Samples of C. gariepinus were collected for a period of for 12 months (between May 2016 and April 2017) from the upstream and downstream of the River and were analyzed using Atomic Absorption spectrophotometry for the determination of heavy metals. From the results it was observed that trace metals bioaccumulated in the tissues of C. gariepinus with high concentrations in the intestine and muscles. Significant variations for upstream and downstream were observed for Cd, Cr, Cu, Pb, Mn and Zn (p<0.05) exception for Iron (p>0.05). The high concentration of Fe and Zn recorded during the study can be attributed to its abundance in the earth crust. Transfer factor index used in this study as a tool to assess the level of bioaccumulation in the studied species showed evidence of bioaccumulation of heavy metals in the tissues which calls for public health concern. However, the level of trace metal were above recommended tolerable limits for most of the metals when compared to world standards for safety of consumption of aquatic organism exception for Pb and Cr. The result of the studies implies that C. gariepinus caught from Orashi River is not safer as a food source for human consumption. However, constant monitoring of the river is emphasized in order to forestall cumulative effects of contamination which may arise in future if not checked.

Abstract –  Mobile Ad hoc Networks consist of mobile nodes which are running randomly. Nodes communicate  with each other without any access point. Due to mobility of nodes, network is easily affected by several types of attacks. In particular black hole attack cause packet dropping, misrouting the information from source to destination. To reduce the effect of this attack, we propose a New Enhanced Proactive Secret Sharing Scheme (NEPSSS) to  detect the black hole nodes and to ensure the data confidentiality, data integrity and authenticity. In first phase of the proposed algorithm, the detection of black hole attack is achieved using trust active and recommendation of the  nodes. In second phase of the work, Enhanced Proactive secret sharing scheme is used to provide the data  authentication and integrity. The simulation results shows the proposed algorithm achieves the better packet delivery ratio,   misbehaviour detection efficiency, fewer packets overhead and  low end to end delay than the existing schemes.

Abstract: -groupoids (non-associative structure) are basic structures in Flocks theory. This theory mainly focuses on distance optimization, motion replication, leadership maintenance with wide range of applications in physics and biology. In this paper, we define some new types of fuzzy ideals of -groupoids called -fuzzy bi-ideals, -fuzzy interior ideals, -fuzzy bi-ideals and -fuzzy interior ideals of -groupoids where  and  with  and  An important milestone of this paper is to provide the connection between classical algebraic structures (ordinary bi-ideals, interior ideals) and new types of fuzzy algebraic structures -fuzzy bi-ideals, -fuzzy interior ideals). Special attention is given to -fuzzy bi-ideals, -fuzzy bi-ideals.
