DoS attack situation changed by many situation elements. To make it easier to network manager's awareness, a DoS attack situation visualization method based on Parallel Coordinates is proposed. In this method, node resource consumption is represented as the values of axes. Resource usages for each node express by a fold line. The overall impact and node resource consumption details of DoS attacks can effectively demonstrate. In addition, interactive K-Means algorithm is used to cluster nodes and color different classifications into different colors. Experimental result shows that the clustering performance is improved without increasing the burden on the system, and the visualization is enhanced.

Resource depletion Dos attacks frequently occur in the network, and it is difficult to defend. In order to observe and prevent such attacks, this paper proposed a method of attack situation assessment based on quality of service. The method applies with weight correction algorithm to enhance the objectivity of the algorithm and reduces the error. Experiments show that the proposed assessment method will be able to effectively indicate the attack posture and provide a basis for network administrators to develop response strategies.

This research is to probe into the jeans' brand image. In this study, we regard the brand image sources as the input, the customer's brand loyalty as the output and the brand asset valuator (BAV) model as the middle treatment of procedures, and then build a full model for evaluating the brand image for jeans.This model probes into three components of brand image in terms of image of product, image of maker and images of competitor, how is it influence between consumer and loyalty of the brand through the impact of four components of brand power measurement, which is brand knowledge, brand honor, brand fitting and differential effect. The scope of this research includes the famous brands of jeans on the market, with the questionnaire survey to the consumers who are wearing jeans with brands, we gather the information and construct a structural equation model (SEM) to prove the adequacy of the brand image's model, and confirm the relationship between hypotheses of the research.

The cylindrical-rectanglar microstrip antennas have been recently studied by many authors. The feeding mechanisms of probe-fed and micro-stripline-fed cases have been considered, and different numerical techniques using the full-wave analysis, the cavity-model method, and the generalized transmission line model (GTLM) theory have been applied. Among these numerical methods, the full-wave analysis is rather complicated and computationally inefficient. On the other hand, both the cavity-model method and the GTLM theory are much simpler and requires less computational effort. The GTLM solution also shows good agreement with the measured data for the case of a probe feed excitation. In this paper, we further apply the GTLM theory to the analysis of cylindrical-rectangular microstrip antennas with a microstrip feedline or using slot coupling. For both feeding mechanisms, the equivalent circuits are described, and the calculated input impedance results are presented.
