In this paper we compare speaker clustering and speech recognition techniques to the problem of understanding patterns of air traffic control communications. For a given radio transmission, our goal is to identify the talker and to whom he/she is speaking. This information, in combination with knowledge of the the roles (i.e. takeoff, approach, hand-off, taxi, etc.) of different radio frequenci...

The toxic effects of Lindane (γ-BHC) on Microcystis aeruginosa were studied under lab culture conditions. Total protein levels, as well malondialdehyde (MDA) levels and superoxide dismutase (SOD) enzyme activity, in algal cells, determined after exposure to different concentrations Lindane. bioaccumulation Lindane, the influence pH dissolved organic matter (DOM) effects, was also evaluated cell...
