High gain observer for a three-cell chopper: Design and experimental results
( John Wiley & Sons, Ltd. , 2014 , Article)As capacitor voltages are necessary for the three-cell DC�DC chopper control, the estimation of such voltages by an observer is attractive solution in terms of cost. However, due to the hybrid behavior of this structure, ... -
Highly accurate solutions of the bifurcation structure of mixed-convection heat transfer using spectral method
( John Wiley & Sons, Ltd. , 2002 , Article)This paper is concerned with producing highly accurate solution and bifurcation structure using the pseudo-spectral method for the two-dimensional pressure-driven flow through a horizontal duct of a square cross-section ... -
Mathematical model for predicting sludge accumulation in septic tanks based on operational parameters: effect of hydraulic mixing
( John Wiley & Sons, Ltd. , 2015 , Article)Reporting sludge accumulation in septic tanks as a constant rate is no longer accepted, and there is a need for a model that predicts sludge accumulation in septic tanks taking into consideration the continuous consumption ... -
Modelling the degradation of vibration characteristics of reinforced concrete beams due to flexural damage
( John Wiley & Sons, Ltd. , 2015 , Article)This paper presents an improved crack model incorporating non-linearity of flexural damage in concrete to reproduce changes in vibration properties of cracked reinforced concrete beams. A reinforced concrete beam model ... -
Multi-component instantaneous frequency estimation using locally adaptive directional time frequency distributions
