This paper presents novel active filter for mitigation electromagnetic interference (EMI) and other adverse effects of pulse width modulation (PWM) inverter-fed AC motor system. An active filter proposed and devised for this system is characterized by sophisticated connection of two small separate filters, capable of mitigating all the adverse effects. This paper provides high frequency models ...
voltammetric techniques have been considered as important methods among the analytical techniques used for the identification and determination of trace concentrations of many biological molecules such as l-ascorbic acid (aa). l-ascorbic acid is an electro-active molecule, though it is difficult to determine its value directly with a majority of electrodes made of carbon and transition metals, ...
notwithstanding a century of prohibition, marijuana is the most widely used illicit substance in canada. due to the growing public acceptance of recreational marijuana use and ineffectiveness of the existing control system in canada, the issue surrounding legalizing this illicit drug has received considerable public and political attentions in recent years. consequently, the newly elected liber...
in this paper we examine the absorption and dispersion properties of a weak probe field via electromagnetically induced transparency (eit) in a four-level system. it is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. it will be shown that the controlling of absorption and dispersion spectru...
