Beyond Where to How: A Machine Learning Approach for Sensing Mobility Contexts Using Smartphone Sensors

Sensors, 2015
This paper presents the results of research on the use of smartphone sensors (namely, GPS and accelerometers), geospatial information (points of interest, such as bus stops and train stations) and machine learning (ML) to sense mobility contexts.

Thermographic studies of outer target heat fluxes on KSTAR

Nuclear Materials and Energy, 2017
A new infra-red (IR) thermography system with high spatial resolution has been installed on KSTAR and is now mainly applied to measure the outer divertor heat load profile.

Origin of the up/down poloidal asymmetric dependence of ELM control in ITER-like RMP configuration in KSTAR

Nuclear Fusion
Recent edge-localized modes (ELM) control experiments via resonant magnetic perturbation (RMP) in KSTAR have shown a strong up/down poloidal asymmetric coupling dependence.

3.6MW Power Supply System of the 170GHz ECH&CD System in KSTAR

EPJ Web of Conferences, 2012
A 3.6 MW (-66 kV/55 A) Gyrotron power supply system was developed for the 170 GHz ECH&CD gyrotron system in KSTAR. This power supply system consists of Cathode Power Supply(CPS), Anode Power Supply(APS) and Body Power Supply(BPS).

Wall conditioning effects of boron powder injection in KSTAR with a tungsten divertor

Nuclear Fusion
Boron powder dropped into KSTAR plasmas decreased the radiated power, core electron density, and $Z_\mathrm {eff}$ , indicating that the ablated and redeposited boron powder helped to condition the plasma-facing surfaces.
