In this study, Chemical Oxygen Demand (COD) from a pharmaceutical wastewater (PhW) was reduced by several techniques such as electro-Fenton (EF), photo electro-Fenton (PEF) and activated sludge (AS) processes and the obtained data were compared with each other. The effects of several parameters such as pH, current density, H2O2/Fe2+ molar ratio, volume ratio of ...

In this paper a novel common mode separation technique for implementing fully differential current buffers is introduced.  Using the proposed method two high CMRR (Common Mode Rejection Ratio) and high PSRR (Power Supply Rejection Ratio) fully differential current buffers in BIPOLAR and CMOS technologies are implemented.   Simulation results by HSPICE using 0.18μm TSMC process for CMOS based st...

This paper presents the analysin ,design and implementation of a high voltage ratio topology of DC-DC converter. The DC-DC converter has high voltage ratio with reduced input current, output voltage and output current ripple, and also reduces the voltage and current rating of power electronics components and compared with conventional boost converter. The voltage stress on the switches are  red...

This study aims to find out how the Current Ratio and Return On Assets (ROA) in assessing Price Earning (PER) with research object of PT Indofood Sukses Makmur, Tbk. Data is taken from financial reports for 2016-2020 period. uses a qualitative descriptive method consisting three variables, namely as independent variables dependent variable. analysis using case studies (non-hypothesis). Based on...

This paper presents the method for evaluation of turns ratio correction inductive current transformer using magnetization curves determined at non-load state and in load conditions. The presented may be applied to determine even a fractional winding factor. standard IEC 61869-2 provides tested CT from measured rms values voltages on its primary secondary state. However, this approach is limited...
