In the recent years, many hostile websites have been using polymorphic JavaScript in order to conceal its code. The virtual execution is considered to be effective to process and detect such types of JavaScript. However, a challenge often encountered with that approach is the mandatory preparation of very detail-oriented environments that may also require specific user-driven events for the malicious...
During mine exploration, the borehole plane / profile are usually digitized by manual in MapGIS or CAD platform at the present, which is not only inefficient, but also difficult to meet the requirements of the maps' accuracy. Based on the results of previous studies, the author researches automatic mapping algorithms based on borehole data, which specifically includes spatial coordinate generation...
According to the complexity of financial system, the model of credit risk assessment based on PSO algorithm and BP neural network integrated is proposed, which in order to improve the accuracy and reliability of risk assessment. First the neural network model of a credit risk evaluation is created, and then PSO algorithm is introduced to optimize the weight and threshold of the neural network, at...
Since different applications have different requests, an already generated DEM does not always suit all the demands of an application. The objective of DEM generalization is the generation of a smooth surface with a lower resolution than the original data, which should preserve topographic features and be appropriate for a smaller scale relief presentation. In this paper, we take a new algorithm-3...
