We are developing two crucial improvements on the time-frequency masking approach to the blind speech separation of underdetermined mixtures when processing anechoic and echoic mixtures. First, the proposed method copes with the usually large amount of delay estimation error that appears in a low frequency band. This step generates a restrictive mask for phase delays on the basis of local and g...

The networks of compromised and remotely controlled computers (bots) are widely used in many Internet fraudulent activities, especially in the distributed denial of service attacks. Brute force gives enormous power to bot masters and makes botnet traffic visible; therefore, some countermeasures might be applied at early stages. Our study focuses on detecting botnet propagation via public websit...

Mokslas – Lietuvos Ateitis Science – Future of Lithuania

Since 1970-ties the research is being carried out for the development of intelligent tutoring systems (ITS) that are trying to imitate human-teachers and their teaching methods. However, over the last decade researchers inspired by the close relationship between emotions and learning have been working on the addition of an emotional component to human-computer interaction. This has led to creat...

Minimax Probabilities for Aubry-mather Problems

In this paper we study minimax Aubry-Mather measures and its main properties. We consider first the discrete time problem and then the continuous time case. In the discrete time problem we establish existence, study some of the main properties using duality theory and present some examples. In the continuous time case, we establish both existence and nonexistence results. First we give some exa...
