A great deal of research interest has arisen in the area of information diffusion since the emergence of online social networks (OSN). Many models for describing how information diffuses in OSN have been proposed. But so far, the mechanisms of information diffusion remain largely unexplored. We try to find the mechanisms from the perspective of both network structure (micro-scale level) and popularity...
Modern web users are exposed to a browser security threat called drive-by-download attacks that occur by simply visiting a malicious Uniform Resource Locator (URL) that embeds code to exploit web browser vulnerabilities. Many web users tend to click such URLs without considering the underlying threats. URL blacklists are an effective countermeasure to such browser-targeted attacks. URLs are frequently...
A method to analyze the similarity between two quantum images of the same size is proposed based on a representation for the quantum images. The similarity value is estimated according to the probability distribution of the results from quantum measurements. The proposed method is fast because a single operation can transform the entire information encoded in two images simultaneously. Two simulation-based...
A Multi-Channel Representation for Quantum Image (MCRQI) is proposed to facilitate the further image processing tasks based on the Flexible Representation for Quantum Image (FRQI). Channel Swapping Operation, One Channel Operation, are proposed as basic image processing operations on MCRQI representation. The simulation experiment results on classical computer show that the channel information of...
The solder joint is one of the key weakness points that influence the reliability of MEMS package, for maximum stress-strain will be produced under high-g impact, which may result in plastic distortion or even crack in solder joint. Based on the dynamic analysis of Finite Element Model (FEM), sensitivity analysis is conducted on a typical MEMS package (Leadless Chip Carrier, LCC) for the dependence...
In this paper we will focus on color problems which occur if we utilize MSR as an image processing technique, and propose a modified Luminance Based MSR (LB_MSR) algorithm. There are two novelties in our algorithm. Firstly, we only process the luminance channel which is obtained by principal component analysis (PCA). PCA provides orthogonality between channels, thus allow the color to remain stable...
