in this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. the concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (ir-tf), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. ir-tfs, which are well c...

In this study three different prominence and speech melody related effects on voice quality were studied using an inverse filtering based method. The hypothesis that prominence as a function of sentence and word stress is signaled with more pressed voice quality was tested. The results indicated discrepancies in the parameterization results, and the original hypothesis could not be confirmed. I...

Can arise from fast and slow responses of opposite sign: G(s) = 1 s + 1 − 2 s + 5 = 3 − s (s + 1)(s + 5) .

Prominence relations in speech are signaled by various ways including such phonetic means as voice fundamental frequency, intensity, and duration. A less studied acoustic feature affecting prominence is the so called voice quality which is determined by changes in the airflow caused by different laryngeal settings. We investigated the changes in voice quality with respect to linguistic prosodic...

in this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. in addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. in the proposed control metho...

We study the stationary state of a simple exclusion process on a ring which was recently introduced by Arndt et al [14,15]. This model exhibits spatial condensation of particles. It has been argued [14, 15] that the model has a phase transition from a “mixed phase” to a “disordered phase”. However, in this paper exact calculations are presented which, we believe, show that in the framework of a...
