In order to meet the requirement of high-compact and hard-real-time outdoor navigation system, to solve the problem of invalid satellite navigation during GPS-denied period, a multi-sensors integrated navigation system is designed in this study. The system is fused with accelerometer, gyroscope, satellite receiver, binocular vision camera and barometer. The Kalman Filter, which is designed for model...
Recently, the threat of Android malware is spreading rapidly, especially those repackaged Android malware. Although understanding Android malware using dynamic analysis can provide a comprehensive view, it is still subjected to high cost in environment deployment and manual efforts in investigation. In this study, we propose a static feature-based mechanism to provide a static analyst paradigm for...
Fast-flux service networks (FFSNs), broadly used by botnets, are an evasive technique for conducting malicious behavior via rapid activities. FFSN detection easily fails in the case of poor performance and causes a high incidence of false positives due to the similarity of an FFSN to a content distribution network (CDN), a normal behavior for load balance. In this study, we propose a localized spatial...
JavaScript code is often obfuscated; given such code, can we tell whether if it is malicious or benign? We propose Obfuscating Causal Relations Finding (OCRF), which addresses this problem. The contributions are the following: (1) careful feature extraction, using domain knowledge (2) no need for de-obfuscation, since our method can be applied to the obfuscated script directly, (3) combined obfuscation...
On automatic modulation there are two approaches, decision-theoretic and statistical pattern. An automatic modulation recognition system to recognize four digital signal classes as: MASK, MFSK, MPSK, MQAM is proposed in this paper, which using decision-theoretic based feature set addition to statistical pattern based feature set with VLBP(variable learning rate back-propagation)BP neural network and...
Automatic modulation recognition of modulation signals is the key problem in non-cooperative communication systems. The method which combines the rough set theory and the neural network is designed for identifying the six modulation types based on the research on the feature set of digital modulation recognition. Simulation results show that the new method simplifies the structure of neural networks...
Dynamic Time Wrapping is a non-linear distance measure solution, widely used in query by humming. This paper have a body of work on cross-sentence retrieval, end point loose, cost function and their improvements to raise DTW performance of query by humming. Based on these researches we build a prototype of hierarchical matching humming system. During the test of database contains 500 songs and 55...
