A Relativistic Double Neutron Star Binary PSR J1846-0513

Publikováno v: The Astrophysical Journal Letters, Vol 964, Iss 1, p L7 (2024)

We report the timing analysis of PSR J1846−0513, a pulsar discovered by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in Commensal Radio Astronomy FAST Survey. The pulsar possesses a spin period of 23.36 ms and a spin-down rate (

Occurrence of pressure-forced meteotsunami events in the eastern Yellow Sea during 2010–2019

Autor: M.-S. Kim, S.-B. Woo, H. Eom, S. H. You

Publikováno v: Natural Hazards and Earth System Sciences, Vol 21, Pp 3323-3337 (2021)

This study examined the occurrence of meteotsunamis in the eastern Yellow Sea and the conceptual framework of a monitoring/warning system. Using 1 min intervals of mean-sea-level pressure and sea-level observations from 89 meteorological stations and

A simple model of solenoidal inductively coupled plasma sources considering finite size

Autor: J. J. Lee, S. J. Kim, K. K. Kim, Y. S. Lee, S. J. You

Publikováno v: AIP Advances, Vol 10, Iss 3, Pp 035008-035008-7 (2020)

This paper proposes an updated transformer model for solenoidal inductively coupled plasma sources that can be applied even in low electron density regions. The proposed model can handle plasma in a finite geometry where the electric fields propagati

EMBEDDED CONTROLLER BUILDING FOR BALL AND BEAM SYSTEM USING OPTIMAL CONTROL SYNTHESIS

Autor: B. M. HUNG, S. S. YOU, H. S. KIM, T. W. LIM

Publikováno v: Journal of Engineering Science and Technology, Vol 12, Iss 6, Pp 1460-1474 (2017)

The controller design for the Ball and Beam system is particularly crucial in the aviation fields due to its likeness to the aircraft control during the flight and landing under turbulent. Since the actual tests on the aircrafts are not possible, the
