System identification of a linear time-invariant (LTI) system can be completed with time-domain or frequencydomain methods. • Time-domain system identification usually involves the analysis of a plant’s response to a step function on its input. Because a step function only takes two values, it can be generated by a digital output. • Frequency-domain system identification finds the gain and phas...

Recombinant Rhodopseudomonas palustris, harboring the carotenoid-metabolizing gene crtI (CrtIBS), and whose color changes from greenish yellow to red in response to inorganic As(III), was cultured in transparent microplate wells illuminated with a light emitting diode (LED) array. The cells were seen to grow better under near-infrared light, when compared with cells illuminated with blue or gre...

This paper presents the performance of solar cells under different electric lighting sources in indoor environments. Experiments are conducted for different solar technologies like polycrystalline Silicon, Amorphous Silicon and DyeSensitized .Measurements are done under illumination from incandescent, fluorescent and LED light sources in this paper. Also, simulations are done to find out the ma...

The main emphasis of this paper is on analyzing the harmonics generated from compact fluorescent lamps (CFLs). Laboratory tests on various CFLs were conducted to tap the load current behavior under different conditions. Then frequency domain analysis is performed to investigate the generated harmonics from CFLs. Harmonic levels of dimmable and non dimmable CFLs are experimentally evaluated and ...
