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.

Nanodiamond Quantum Sensors for Probing Free Radical Biology
Advanced Functional Materials, EarlyView.Free radicals play key roles in cellular signaling and disease but remain difficult to measure in living systems. Nanodiamonds (NDs) with nitrogen‐vacancy (NV) centers enable quantum sensing of local magnetic noise via T₁ relaxometry, providing nondestructive radical detection in living cells.

Simulation of a single-phase active power filter based ANN controller [PDF]
, 2013 This project presents the employment of a single-phase active power filter (APF) to compensate harmonics generated by battery charger. The presence of the harmonics leads to various problems and poor power quality.

Advanced Functional Materials, EarlyView.This work introduces a regionally localized electrolyte (RLE) that spatially separates ether‐ and carbonate‐based functions to stabilize both Li metal and high‐voltage cathodes. An immobilized ether‐rich layer directs Li+ transport, activates LiNO3 locally, and forms a uniform LiF‐rich SEI, enabling lower overpotential, uniform deposition, and long ...
