This paper reports the synthesis of HCl-doped Au@polyaniline(Pani) nanocomposite fibers by the in situ oxidative polymerizationof aniline in the presence of gold nanoparticles. Thusprepared nanocomposite fibers were characterized by SEM,TEM, XRD, Raman spectroscopy, XPS, UV-visible diffusedreflectance spectroscopy, TGA, and DSC. The Au@Paninanocomposite fibers showed superior DC electrical conductivityto HCl-doped Pani, which might be due to the increasedmobility of the charge carriers after the incorporation of goldnanoparticle in Pani. Au@Pani also exhibited a better ammoniasensing and recovery response than Pani, which might bedue to the increase in the surface area of Pani after the incorporationof gold nanoparticles.

polymerization of aniline in the presence of V2O5 and cetyltrimethylammonium bromide, as a surfactant. The prepared composite nanofibers were characterized by scanning electron microscopy, transmissionelectron microscopy, X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, UV–visible diffused reflectance spectroscopy, thermogravimetric analysis, and differential scanningcalorimetry. The V2O5@Pani composite nanofibers showed higher DC electrical conductivity than Pani,which might be due to the increased mobility of the charge carriers after the incorporation of V2O5. V2O5@Pani also showed a better ammonia sensing and recovery response than Pani due to thesynergistic effect of V2O5 and Pani.

GN@PVC nanocomposite fiber was synthesized by simple facile deposition technique using THF as asolvent. The as-prepared GN@PVC nanocomposite fibers were characterized by BET, Raman, XPS, XRD,TEM, TGA, DRS and SEM. BET analysis of GN@PVC showed 70% enhancement in the surface area over PVCfibers. The thermal stability of GN@PVC nanocomposite fibers was found to be highly dependent on theweight percent of GN and nanocomposite with 3 wt.% GN showed 8% increase in glass transitiontemperature and 36% improvement in the activation energy for thermal degradation. Moreover,GN@PVC nanocomposite fibers showed lower band gap in comparison to PVC.

This paper reports the synthesis of camphor sulfonic acid (CSA) doped PANI/GN composite nanofibers bythe in situ chemical oxidative polymerization of aniline in the presence of cationic surfactant cetyl trimethyl ammonium bromide (CTAB). The as-synthesized composite nanofibers were examined by scanningelectron microscopy, transmission electron microscopy, X-ray diffraction, Raman spectroscopy, UV–visdiffused reflectance spectroscopy, and thermogravimetric analysis. The CSA-doped PANI/GN compositenanofibers showed higher DC electrical conductivity than PANI, which was attributed to the enhancedmobility of the charge carriers after the incorporation of GN into the PANI/GN composite nanofibers. ThePANI/GN composite nanofibers also showed improved DC electrical conductivity retention at 413 K, whichmight be due to the synergistic effects of GN and PANI in the composite structure.

The proposed IMC-PID tuning method is extension of the recently published setpoint overshoot method (2010). It is one step procedure to obtain the PI/PID setting which gives the better performance and robustness. The method requires one closed-loop step setpoint response experiment using a proportional only controller with gain Kc0. Based on simulations for a range of first-order with delay processes, simple correlations have been derived to give PI/PID.filter controller settings. The controller gain (Kc/Kc0) is only a function of the overshoot observed in the setpoint experiment. The controller integral and derivative time (τI and τD) is mainly a function of the time to reach the first peak (tp). The proposed tuning method shows better performance than the setpoint overshoot method (2010) for broad range of processes.
Dual three Phase Operation of Dual Airgap Permanent Magnet Vernier Machine Having a Yokeless Rotor

In order to increase the speed range of permanent magnet machines in constant power regions, diff erent techniques including multi-phase confi gurations are usually adopted. This paper presents the dual three-phase operation of a novel dual-airgap permanent magnet vernier machine having a yokeless rotor. The presented machine comprises two stators, each having a three-phase winding, and a sandwiched single yokeless rotor. The outer and inner stator windings are treated as two diff erent sets of three-phase windings to accomplish the dual three-phase operation. To achieve this, three-phase currents are supplied to these winding sets by considering two cases: (i) out-of-phase currents having the same magnitude and (ii) in-phase currents with varying magnitudes. This dual three-phase operation provides better effi ciency in the in-phase operation. The presented yokeless model has a very high mutual inductance which improves the fl ux linkage between two stators. Moreover, the harmonic analysis and open circuit fault analysis are presented to confi rm the validity of the presented dual three-phase operation compared to the three-phase operation. 2D-FEM analysis is used to investigate the performance of the presented machine for dual three-phase operation.
