The development of novel potentiometric sensors for cobalt (II) ions in aqueous solutions is reported here. Cobalt-polymer composites have been used to produce cobalt-selective membranes. Analytical characteristics of the proposal sensors have been determined. Morphological investigation allows revealing the formation of the endless conductive cluster in the threshold area of cobalt metal concentrations. The existence of such a structural unit makes possible the usage of the elaborated composites as a sensitive membrane for ion-selective electrodes. Results obtained from X-ray photoelectron spectroscopy prove the formation of cobalt-polymer complexes in these composites. Strong cobalt-polymer interaction is detected by the X-ray diffraction method. Metal - polymer complexes determine the electrochemical properties of the composite ion-selective membranes. Composite cobalt-selective electrodes can find application in a chemical or ecological monitoring for the presence of Co (II) ions. © 2011 IEEE.

Aiming at the vehicle power train, system dynamic optimization is profoundly studied based on the system torsional vibration characteristics analysis. First, based on the concentrated mass method, the general torsional vibration model of vehicle power train is established and solved after parameters' (inertia, stiffness, and damping) matrix and mathematic constraint conditions are acquired. Furthermore, both free vibration and forced vibration characteristics are analyzed. Second, the effects of the coupling stiffness on the dynamics behaviors of power train are thoroughly analyzed. The sensitivity analysis procedure is explored. And sensitivity models of both free and forced vibration feature parameters are deduced. Finally, dynamic optimization theory model and program are constructed based on genetic algorithm. The optimization results indicate that the proposed optimization method could contribute to the sharp attenuation of system torsional vibration. © SAGE Publications Ltd.
