Compensation of voltage Sag using STATCOM
, 2018 Due to unpredicted non-linear loads, power quality problems, a raise in the transmission system. One such problem is voltage sag. Voltage sag is caused by the non-linear load which demands reactive power, but the balanced 3F source provides required ...

European Eating Disorders Review, EarlyView.ABSTRACT Objective Chronic malnutrition, hypothermia, and hormonal imbalance in anorexia nervosa (AN) may impair capillary structure and perfusion. This study aimed to describe the nailfold videocapillaroscopy (NVC) findings in adolescents with AN and atypical AN (AAN), to assess their association with Raynaud's phenomenon (RP), and evaluate ...

Energy Science &Engineering, EarlyView.SSA‐optimized fuzzy‐PI control reduces battery stress in flywheel–battery hybrid energy storage systems by shifting transient power fluctuations to the flywheel. The strategy decreases ampere‐hour throughput by 46.1% and rainflow damage by 71% while maintaining stable DC‐bus regulation.

Energy Science &Engineering, EarlyView.Formed ~1.4 Ga, the carbonate reservoir of the Jixian System is a key geothermal reservoir in northern China. Differential basin–mountain evolution since the Cenozoic led to distinct reservoir‐forming histories; consequently, this same reservoir shows marked productivity contrasts between intramontane basins and the large rift Bohai Bay Basin ...

Environmental Toxicology and Chemistry, EarlyView.Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...
