IDENTIFICATION OF SOME CARCINOGENIC POLYCYCLIC AROMATIC HYDROCARBONS IN BANGLADESHI VEHICLES EXHAUST TAR BY GAS CHROMATOGRAPHY-MASS SPECTROPHOTOMETER

open access: yesIndonesian Journal of Chemistry, 2010
A more sensitive GC-MS method has been established for the determination of some carcinogenic polycyclic aromatic hydrocarbons (PAHs) in vehicles exhaust tar samples. The tar samples were extracted using dichloromethane (DMC): n-hexane solvent mixture. A

P-resonant control for the neutral point of three phase inverter [PDF]

open access: yes, 2014
In this project, a Proportional resonant (PR) current controller is proposed to maintain a balanced neutral point for a three-phase four wire inverter, which can be used in microgrid applications. The neutral-point circuit consists of a conventional
