Pitch marking is very significant in speech signal processing. In a text-to-speech (TTS) system based on the Time-Domain Pitch-Synchronous Overlap-Add (TD-PSOLA) method, robust estimation of pitch marks (PM) is especially important to the modification of the time and pitch scale of a speech signal in order to match it to that of the target speaker. The aim of this paper is to improve the accura...

The article analyses generators generating efficient electricity at low speed water and wind flows. High rotating are used in farms micro-hydropower. Reduction gears to provide the with required number of rotations. use reduction power system leads a decrease efficiency additional capital costs. study analyzed multipolar synchronous generators. Both permanent magnet generate electromotive force...

The amount of waste can be overcome, some efforts are needed to reduce it. This research will focus on the numerical model a solid power plant. Researchers replace turbine with an impact which have specification certain pressure, rotates generator purpose this is get rms voltage generator, where capable supplying voltage. effort made convert energy into electrical energy. Generators main topic ...

Single-pole switching scheme is widely used in the Extra High Voltage system. However, the substantial negativesequence current injected to the turbine-generators imposes the electromagnetic (E/M) torque of double systemfrequency components during the dead time (between single-pole clearing and line reclosing). This would induce supersynchronous resonance (SPSR) torque amplifications on low pre...

The radial and tangential force components acting on each sub-conductor of a Roebel bar in large generator lead to mechanical vibration the stator bars slot. This double-frequency results additional stress fixation materials slot causes insulation deterioration looseness bars. Particularly during short circuits, are subjected immense forces. Understanding origin these vibrations developing mode...

The paper elaborates on the mathematical model of electric power system with several synchronous generators and in this are presented by a non-linear model. By applying such model, impact manner supplying excitation generator’s angular stability was researched circumstances occurrence short circuit network. established enables analysis extensive disruptions for case generator separate self-exci...

We investigated the effects of chronically applied PKC-stimulating phorbol esters on subcellular CFTR expression and localization in polarized HT-29 Cl.19A monolayers. Modulation of PKC activity with the PKC-beta-specific agonist 12-deoxyphorbol 13-phenylacetate 20-acetate (DOPPA) or nonisoform-selective PMA altered monolayer CFTR immunofluorescence. A decrease in the CFTR signal within the lum...
