In this paper, we focus on the problem of ad dissemination in the cluster based vehicular ad hoc networks (VANETs). Our goal is to stimulate vehicles to disseminate the ad packets cooperatively in a stable cluster based VANET, meanwhile a stable clustering algorithm for N-hop clustering is proposed. To stimulate the vehicles to cooperate, the VANETs are(More)
Lots of studies on myocardial infarction (MI) computer assisted diagnosis are based on certain important ECG components which only account for local information. 12-Lead ECG signals which were regarded as hyper-dimensional time-series data were utilized to extract features from global information in this study. Existing feature extraction techniques for(More)
The detection for motive small target in infrared image sequence has become a hot topic nowadays. A novel detect algorithm of dim and small infrared target based on temporal 2 χ test, which aims at disadvantages of algorithm complexity, large amounts of data to process, high capacity memory demand in concerned algorithm, is proposed. Theory basis of(More)
This paper presents two game models based on stimulating mechanism that efficiently stimulate cooperation of the commercial ad dissemination system in vehicular ad hoc networks (VANETs). Firstly, two different coalitional tree game based on the contributions of all vehicles are proposed. Secondly, two corresponding stable payoff allocation mechanisms are(More)
From the perspective of consumers, taking "Changbai Mountain Ginseng" as an example, the paper has proved the influences of geographical brand image on consumers’ behaviors. And further more, it has confirmed the significant adjustment function of WOM information on the relationship between geographical brand image and consumers’ behavioral intentions. The(More)
To solve the problems of difficulty in denoising of aero-optical degraded image due to aero-optical effects, a denoising algorithm based on improved Nonsubsampled Contourlet transform(NSCT) is proposed. Firstly, improved NSCT disassembly was constructed; secondly, adaptive edge orientation, fusion and repair were done. Based on this, denoising of non-edge(More)
