Low Mach number limit for the diffusion approximation model in radiation hydrodynamics at equilibrium-diffusion regime
Kwang-Il Choe, Dae-Won Choe, Myong Chol Pak
The low Mach number limit for the compressible viscous diffusion approximation model arising in radiation hydrodynamics is rigorously justified. For the 3-D Cauchy problem, the sol…
Methods of Fitting experimental data in several amplifiers for single spot radiometer
Kwang Rim Choe, Myong Chol Pak
Single spot radiometers are widely used to estimate temperature of body heated by high temperature, specially blast furnace, glass fusion, boiler of power plant, and so on. In prev…
Microstructure and wear resistance of Fe-Cr-C-Mo-V-Ti-N hardfacing layers
Won Chol Son, Yong Gwang Jong, Myong Chol Pak +1
In this paper, to improve wear resistance of components such as screws under severe friction-wear, Fe-Cr-C-Mo-V-Ti-N hardfacing coatings were further developed. The hardfacing coat…
Influence of geometric structure, convection, and eddy on sound propagation in acoustic metamaterial with turbulent flow
Myong Chol Pak, Kwang-Il Kim, Hak Chol Pak +1
The problem of reducing noise in the transportation is an important research field to prevent accidents and to provide a civilized environment for people. A material that has recen…
On the evaluation of spinnability of metallic materials in the powerful spinning process: a review
Un Chol Ri, Kwang Myong Kye, Myong Chol Pak
Currently, the rapidly developing powerful spinning processes of metals are widely used in many industrial sectors including those requiring high precision processing of metal mate…
Recrystallization Characteristics of Catalytic Alloy and Graphite in Diamond Synthesis
Sang Jun Cha, Myong Chol Pak, Kwang-Il Kim +1
We first consider the recrystallization characteristics of catalysis alloy and graphite in the process of diamond synthesis under the condition of super high pressure and high temp…
On Physical Layer Security over Fox's -Function Wiretap Fading Channels
Long Kong, Georges Kaddoum, Hatim Chergui
Most of the well-known fading distributions, if not all of them, could be encompassed by Fox's -function fading. Consequently, we investigate the exact and asymptotic behavior o…
New discrete method for investigating the response properties in finite electric field
Myong Chol Pak, Nam-Hyok Kim, Hak-Chol Pak +1
In this paper we develop a new discrete method for calculating the dielectric tensor and Born effective charge tensor in finite electric field by using Berry's phase and the gauge…
Spin Transport in the heterogeneous structure containing Topological Insulator and Diluted Magnetic Semiconductor
Myong Chol Pak, Kwang-Il Kim, Hak Chol Pak +2
In this paper, we discuss spin transport in topological insulator (TI) and diluted magnetic semiconductor (DMS) heterogeneous structures. In DMS / FM (Ferromagnetic Metal) heteroge…
