Malignant tumors appear to own the ability to recruit normal tissue cells that contribute to the tumorigenesis process by creating the “tumor microenvironment”. MMPs, is one of the most significant family of proteinases that are related to tumor microenvironment. Recent understanding of MMPs has recognized its role as modulators in tumor microenvironment; however, the current strategies for in vivo...
A nested model with multiple features is represented to accurately detect moving objects and their shadows in outdoor and indoor scenes, even when the moving objects and their shadows have similar color to the background or when there is background motion. Bag of features (color, texture and movement patterns) is first extracted in each frame of an image sequence, and its temporal variation is calculated...
We present a two-stage method to accurately segment single or multiple moving objects and their shadows, especially when the moving objects have similar chromaticity and intensity to their shadows or when they are immersed in the shadows of other moving objects. Our algorithm first detects potential shadows via brightness ratios at each motion region, which is already separated from the background...
Computer network collaborative defense is used to protect networks from collaborative attacks. To ensure the credible of defense entities, trust relationships are necessary to be established. When there are not enough history records for reputation evaluation, the reputation bootstrapping technique to establish an initial reputation value for newcomers based on limited record about their past behaviors...
Botnets are one of the most serious threats to Internet security. Isolated and single point security defense technologies can't effectively counteract large-scale, distributed botnet attacks, such as Spamming and Distributed Denial of service attack. Collaboration among different kind of security devices is needed. To solve this problem, we proposed a conceptual model of botnet collaborative defense...
Clustering is one of the most popular methods for data analysis, which is prevalent in many disciplines such as image segmentation, bioinformatics, pattern recognition and statistics etc. The most popular and simplest clustering algorithm is K-means because of its easy implementation, simplicity, efficiency and empirical success. However, the real-world applications produce huge volumes of data, thus,...
Due to limited storage space and heavy workload, container stacking in many Asian seaports is of high density. The method of yard storage template design, which effectively allocates yard space for incoming containers, is critical for utilizing yard storage resources and facilitating yard operations. This research studies the problem with a periodical vessel calling pattern that resource planning...
As the "killer weapon" of future informationization war, Informationization Materiel System (IMS) has plentiful information technology, complex system configuration and high reliability requirement. The prominent characteristics of IMS and the primary methods of reliability prediction are analyzed. The upper limit and lower limit method adapted to reliability prediction of complex material...
