Single phase inverter design based on selective harmonic elimination method
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2013 Minimization of harmonic distortions in voltage source inverters' output wave form is very important. In this paper, a single phase inverter design that can change the operating frequency between 5 Hz 50 Hz to achieve the keeping the voltage/frequency ...

Dynamics of spin transport in voltage-biased Josephson junctions
, 2007 We investigate spin transport in voltage-biased spin-active Josephson junctions. The interplay of spin filtering, spin mixing, and multiple Andreev reflection leads to nonlinear voltage dependence of the dc and ac spin current.

Evaluasi Distorsi Harmonisa Tegangan Pada Sistem Tenaga Listrik Di Rumah Sakit Panti Wilasa Citarum Semarang [PDF]
, 2011 One of the factors that affect power quality is harmonic distortion. Harmonic distortion is measured by the value of Total Harmonics Distortion, THD. THD of Voltage harmonics always be a guide to the basic values of the instantaneous waveform.

First harmonic measurements of the spin Seebeck effect
, 2018 We present measurements of the spin Seebeck effect (SSE) by a technique that combines alternating currents (AC) and direct currents (DC). The method is applied to a ferrimagnetic insulator/heavy metal bilayer, Y$_3$Fe$_5$O$_{12}$(YIG)/Pt.
