Late Holocene environmental reconstructions and their implications on flood events, typhoon, and agricultural activities in NE Taiwan

Autor: L.-C. Wang, H. Behling, T.-Q. Lee, H.-C. Li, C.-A. Huh, L.-J. Shiau, Y.-P. Chang

Publikováno v: Climate of the Past, Vol 10, Iss 5, Pp 1857-1869 (2014)

We reconstructed paleoenvironmental changes from a sediment archive of a lake in the floodplain of the Ilan Plain of NE Taiwan on multi-decadal resolution for the last ca. 1900 years. On the basis of pollen and diatom records, we evaluated past flood

How significant is submarine groundwater discharge and its associated dissolved inorganic carbon in a river-dominated shelf system?

Autor: Q. Liu, M. Dai, W. Chen, C.-A. Huh, G. Wang, Q. Li, M. A. Charette

Publikováno v: Biogeosciences, Vol 9, Iss 5, Pp 1777-1795 (2012)

In order to assess the role of submarine groundwater discharge (SGD) and its impact on the carbonate system on the northern South China Sea (NSCS) shelf, we measured seawater concentrations of four radium isotopes 223,224,226,228Ra along with carbona

Analysis of a Piezoelectric Generator Under an Elastic Wave

Autor: Seung-Moon Han, C. S. Huh

Publikováno v: IEEE Transactions on Plasma Science. 45:3001-3006

A piezoelectric generator (PEG) under propagation of an elastic wave is studied. A PEG under an elastic wave shows a different phenomenon compared to a shock wave, especially in pulse rise time. With the shock wave, the rise time of the generated imp

Study of High-Voltage Impulse Generation Using Piezoelectric Materials Under Elastic Wave

Autor: Seung-Moon Han, C. S. Huh

Publikováno v: IEEE Transactions on Plasma Science. 44:1429-1434

This paper presents a high-voltage impulse generated using piezoelectric materials by an elastic wave. The impact method was a high-pressure gas gun with projectiles and the type of stress wave was an elastic wave. The results were different from the

THE VALIDATION AND CORRECTION OF THE APPROXIMATION EQUATION USED FOR THE DIRECT CALCULATION OF THE EFFECTIVE FREQUENCIES OF EMP WAVEFORMS

Autor: Seung-Moon Han, J. J. Bang, C. S. Huh

Publikováno v: Journal of Electromagnetic Waves and Applications. 25:1412-1421

An effective frequency range approximation method was developed in this study. The method enables one to find the -3 dB effective cut off frequency ranges of EMP waveforms directly from the rise time and the FWHM. The conventional -3 dB as constant K

Susceptibility and Coupled Waveform of Microcontroller Device by Impact of UWB-HPEM

Autor: C. S. Huh, Seung-Moon Han, Joo-Il Hong, S. M. Hwang, Jin Soo Choi

Publikováno v: Journal of Electromagnetic Waves and Applications. 24:1059-1067

Modern electronic circuits are important to communication, traffic systems, and security systems. An intentional threat to these systems could result in casualties and economic disaster. This study examined the damage effects to a microcontroller dev

A New Method for the Compensation of Coaxial Cable Loss While Measuring EMP Signals

Autor: Seung-Moon Han, C. S. Huh, Jin Soo Choi

Publikováno v: Journal of Electromagnetic Waves and Applications. 23:1991-2000

The accurate measurement of fast rise time EMP is critical. The loss and dispersion characteristics of signal measurement cables cause distortion in these measurements. To compensate for a distorted pulse, an appropriate compensation method is essent

Susceptibility of CMOS IC Devices Under Narrow-Band High Power Electromagnetic Waves by Magnetron

Autor: C. S. Huh, S. M. Hwang, Joo-Il Hong

Publikováno v: Journal of Electromagnetic Waves and Applications. 23:571-582

We investigated the damage effects of CMOS IC devices manufactured using three different technologies under narrow-band high power electromagnetic (NB-HPEM) waves by magnetron. The output of NB-HPEM waves was controlled from 0 to 1 kW, and the narrow
