    Analysis of speech often begins with study of the vocal tract that created it. Bird vocalizations and human speech are generated by similar processes. This suggests that LPC coefficients extracted from birdsong samples could retain enough information to permit identification of species. In this paper we train a back-propagation neural network to recognize bird songs. We generated test and training... View full abstract»

    Traditional induction motor models are either 60-Hz models for steady-state operation or dq0 models for transient analysis. This paper presents a general induction-motor model based directly on phase coordinates. Stator and rotor windings are seen as coupled coils, much like a transformer. For transient analysis, this model is basically the same (apart from the mechanical equations) as the standar... View full abstract»

    It is well documented that any given harmonic (or any given oscillation) on the AC side of an HVDC power converter is converted into frequencies on the DC side with frequency shifts based on multiples and complements of the fundamental frequency of the AC power system. In a similar fashion, oscillations on the DC side are converted to new frequencies on the AC side. This paper combines many of the... View full abstract»

    This paper discusses the modelling aspects of local load at an HVDC converter terminal. In the CIGRE benchmark model for instance, the local load is modelled as part of the Thevenin equivalent of the AC system. Alternately, the local load could be modelled explicitly at the converter terminal. The Thevenin equivalent would then include only the remote AC system. This paper presents the simulation ...
