With the expansion of the energy market, safe and stable operation of the electrical power
system has become an important issue. In an effort to achieve this goal, much research has …

Solenoid valves are widely used to control fluid flow in various mechanical systems. If the
valves do not function properly, the mechanical systems can lose their ability to control the fluid …

… This study utilizes data from the 307-meter Boseong observation tower to analyze the
seasonal variability of land-atmosphere interactions. During the summer season, high solar …

This paper proposes a fault diagnosis method for solenoid valves in urban railway braking
systems. For dominant failure modes of solenoid valves, sensor signals including electrical …

KSTAR Doppler reflectometer (DR) is designed based on frequency steering phased array
antenna (FSPAA) operating in X-mode over the full V-band (50–75 GHz). In the FSPAA …

Classifying and monitoring the L-, H-mode, and plasma-free state are essential for the stable
operational control of tokamaks. Edge reflectometry measures plasma density profiles, but …

In Korea, urban railway cars are typically maintained using the strategy of predictive
maintenance. In an effort to overcome the limitations of the existing strategy, there is increased …

We report experimental observations on the effect of plasma boundary shaping towards
balanced double-null (DN) configuration on the plasma performance in KSTAR. The transition …

… It was installed over a path length of 11.4 km that crosses the bay between Boseong and
Goheung, optimizing it for detecting weather changes. Additionally, A spectrum of the …
