This paper presents a new method based on enhancement algorithms in Empirical Mode Decomposition (EMD) and Discrete Wavelet Transform (DWT) domains for ECG signal denoising. Unlike the conventional EMD based ECG denoising methods that neglect a number of initial IMFs containing the QRS complex as we...

Two new topologies of single-phase AC-DC converter using Buck and Buck-Boost conversion with low input current THD and high input power factor are proposed. Instead of using a single phase rectifier followed by a boost DC-DC converter, or using a bridge rectifier with two diodes and two switches, th...

Bangladesh is a developing country facing with acute electricity shortage. The rural communities of Bangladesh are the worst sufferers of this crisis having limited or even in many cases no access to grid electricity. Solar energy has been proven to be a very promising resource to improve the ongoin...

To topologies of single-phase Ćuk AC-DC converters with low input current THD and high input power factor are proposed. Instead of using a single phase rectifier followed by a boost DC-DC converter, or using a bridge rectifier with two diodes and two switches, the rectifier's input is chopped at hig...

Two topologies of single-phase Buck and Boost AC-DC converters are presented. Instead of using a single phase rectifier followed by a boost dc-dc converter, or using a bridge rectifier with two diodes and two switches, the rectifier's input is chopped at high frequency during positive and negative c...

Natural gas is the principal indigenous resource for power generation in Bangladesh. Use of other conventional fossil fuels like petroleum and coal are quite insignificant with respect to the use of natural gas. The gas reserve of Bangladesh is depleting fast because of this heavy dependence on gas....
