Use of power electronic converters with nonlinear loads produces harmonic currents and reactive power. An active power filter will only provide the solution for these two problems by giving the compensating current to the supply time to time. However, the shunt active power filter with PI type of controller is suitable only for a given load. If the load is varying, the proportional and integral gains...
Shunt active power filter, when used with nonlinear loads, provides an elegant solution for reactive power compensation as well as harmonic mitigation leading to improvement in power quality. The present study deals with fuzzy logic control and neuro fuzzy control for Shunt active power filter. Neuro fuzzy logic has improved THD when compared to fuzzy logic controller and it is demonstrated through...

Edge detection plays a vital role in medical imaging applications such as MRI segmentation. Magnetic resonance imaging (MRI) is an imaging technique used in medical science to diagnose tumors of the brain by producing high quality images of the inside of the human body, by using various edge detectors. There exists many edge detector but still, need for research is felt in order to enhance their performance...
The DNA microarray classification is one of the most popular technique among researchers and practitioners. In microarray data analysis, huge useful information may be lost due to irrelevant and insignificant features of the dataset. To overcome this drawback of the data set, only those features are selected which have high relevance with the classes and high significance in the feature set. In this...
Shunt Active Power Filter (SAPF), when used with non linear loads, provides an elegant solution to reactive power compensation as well as harmonic mitigation leading to improvement in power quality. The present study deals with fuzzy logic control for SAPF. Its superiority over PI type of controller is demonstrated through simulation results.
The effort involved in developing a software product plays an important role in determining the success or failure. In the context of developing software using object oriented methodologies, traditional methods and metrics were extended to help managers in effort estimation activity. Software project managers require a reliable approach for effort estimation. It is especially important during the...
