    This paper proposes a data hiding with high visual quality in stego-images so that malicious invaders are hardly aware of the existence of the embedded message. Due to high visual quality and good embedding capacity, we also apply our scheme with region of importance (ROI) for protecting the important part of an image. The overload, location map of ROI, is compressed with run length encoding (RLE)... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (297 KB) | HTML iconHTML

    Identifying dependencies and relationships amongst data collected from disparate sources is a difficult problem. When the data to be analyzed are geo-spatial data, the problem becomes harder because meaningful data dependencies may not be derived until the right granularity of geo-spatial objects is used to organize the data. We propose a computational framework in which dependencies between geo-s... View full abstract»

    The energy storage system creates optimum conditions for energy regeneration in urban transit systems. The energy storage system is able to store and discharge energy at an extremely rapid rate. This enables a complete exchange of energy between vehicles, even when they are not braking and accelerating at precisely the same time, as is most frequently case in everyday service. The benefits of the ... View full abstract»

    Electric arc furnaces are one of the most severe sources to induce voltage flickers and hard to make an analysis model due to its chaotic characteristics. In this paper, a practical modeling strategy for electric arc furnaces is suggested. By using this model, the flicker phenomena induced by electric arc furnaces are simulated and analyzed to find out solutions for compensation. To compensate vol... View full abstract»

    Translation is a process that allows people to learn and comprehend others' ideas or cultures in their own language. Such knowledge sharing will bring major advancement on society and the economy. A translation groupware, that allows two or more human translators to edit the output of machine translation at different times and different places, is developed in order to overcome the limitation of h...

    Addressing the problem of spam emails in the Internet, this paper presents a comparative study on Nai¿ve Bayes and Artificial Neural Networks (ANN) based modeling of spammer behavior. Keyword-based spam email filtering techniques fall short to model spammer behavior as the spammer constantly changes tactics to circumvent these filters. The evasive tactics that the spammer uses are themselves patt... View full abstract»
