A new approach to averaging level control
Elsevier (2011-09)In this paper, a new simple algorithm for averaging level control is presented. The proposed algorithm is based on the use of a static nonlinear controller to improve the input flow filtering by reducing the slope of the ... -
Processing of poly(lactic acid)/organomontmorillonite nanocomposites: microstructure, thermal stability and kinetics of the thermal decomposition
Elsevier (2011-12-15)The degradation during the melt processing of poly(lactic acid) (PLA) and its nanocomposites with different contents (0.5 and 2.5%) of an organomodified montmorillonite (OMMT) promoted physical and chemical changes in their ... -
Preparation of nanocrystalline TiO2 electrodes for flexible dye-sensitized solar cells: influence of mechanical compression
American Chemical Society (2012)Nanocrystalline TiO2 electrodes were prepared using binder-free TiO2 paste on conductive ITO-PEN substrates by the doctor-blade method at significantly low temperature (140 °C), and the electrodes were further processed ... -
Power management strategies and energy storage needs to increase the operability of photovoltaic plants
American Institute of Physics (2012)This paper analyzes the effect of introducing an energy storage (ES) system in an intermittent renewable energy power plant such as a photovoltaic (PV) installation. The aim of this integration is to achieve an improvement ... -
Biotic degradation of poly(DL-lactide) based nanocomposites
Elsevier (2012)Amorphous PLA nanocomposites based on organic modified kaolinite (KAO) and montmorillonite (MONT) at 4 wt.% were prepared by melt blending and then biodegraded in compost. All materials showed effective degradation in ... -
