Continuous wavelet transform for ferroresonance phenomena in electric power systems
Akıncı, Tahir Çetin; Ekren, Nazmi; Şeker, Serhat; Yıldırım, Sezen (Elsevier Sci Ltd, 2013)The common characteristics of a nonlinear system are multiple equilibrium points, limit cycles, jump resonance and sub-harmonic generation. Ferroresonance is also a nonlinear electrical phenomenon, which occurs frequently ... -
Energy saving in lighting system with fuzzy logic controller which uses light-pipe and dimmable ballast
Görgülü, Sertaç; Ekren, Nazmi (Elsevier Science Sa, 2013)Approximately, 20% of the electricity consumed in the world is spent for lighting. More efficient utilization of the sun, as a natural source of light, for lighting would save electricity used for lighting. The aim of this ... -
