The WWW is currently experiencing a revolutionary growth due to numerous emerging tools, techniques and concepts. Digital journals thus need to transform themselves to cope with this evolution of the web. With their growing information size and access, conventional techniques for managing a journal and supporting authors and readers are becoming(More)
Keywords: Health care Fall detection Unsupervised classification Source separation Mel-frequency cepstral coefficient One class support vector machine a b s t r a c t We present a novel unsupervised fall detection system that employs the collected acoustic signals (footstep sound signals) from an elderly person's normal activities to construct a data(More)
In this work we propose a new binaural spectral subtraction method for the suppression of late reverberation. The proposed approach is a cascade of three stages. The first two stages exploit distinct observations to model and suppress the late reverberation by deriving a gain function. The musical noise artifacts generated due to the processing at each(More)
Source separation algorithms that utilize only audio data can perform poorly if multiple sources or reverberation are present. In this paper we therefore propose a video-aided model-based source separation algorithm for a two-channel reverberant recording in which the sources are assumed static. By exploiting cues from video, we first localize individual(More)
Today's evolving cyber security threats demand new, modern, and cognitive computing approaches to network security systems. In the early years of the Internet, a simple packet inspection firewall was adequate to stop the then-contemporary attacks, such as Denial of Service (DoS), ports scans, and phishing. Since then, DoS has evolved to include Distributed(More)

A novel multimodal (audio-visual) approach to the problem of blind source separation (BSS) is evaluated in room environments. The main challenges of BSS in realistic environments are: sources are moving in complex motions and the room impulse responses are long. For moving sources the unmixing filters to separate the audio signals are difficult to calculate(More)
Exoplanets, short for extra solar planets, are planets outside our solar system. They are objects with masses fewer than around 15 Jupiter-masses that orbit stars other than the sun. They are small enough so they cannot burn deuterium in their cores, yet large enough that they are not so-called dwarf planets like Pluto.
In this study, we investigate the downloads behavior of readers for two well-known IEEE journals in the field of education, i.e., IEEE Transactions on Learning Technologies (TLT) and IEEE Transactions on Education (ToE). In our analysis, we found that articles in both journals are not downloaded rapidly in earlier months. The majority of articles reach to(More)
