| ○ | Conference paper | Study of Backscattering Effects on Particle Identification | One of the consequences of having a high-density calorimeter as part of an experiment is a large number of secondary shower particles generated in the calorimeter - some of which scatter back up towards the charge measurement devices. This so-called "backscatter effect" can interfere severely with accurate charge measurement of the primary nucleus, especially at high energies, as the number of backscattered particles increases with the incident energy. In this analysis, we study the effect of backscattered particles on particle identification by simulating the ISS-CREAM instrument detector model response using the GEANT3 simulation package [1] with the FLUKA hadronic model [2]. Our study shows the importance of the fine segmentation of the charge detectors above the calorimeter. This segmentation minimizes backscattered particle contamination in the same charge detector segment as the incident particle, which helps avoid charge misidentification. Here we present simulation results regarding charge measurements, including tracking resolution, backscattering effects, and charge determination efficiency. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0) | Aggarwal, S.; Amare, Y.; Angelaszek, D.; Bowman, D.; Chen, Y.C.; Choi, G.H.; Copley, M.; Derome, L.; Eraud, L.; Falana, C.; Gerrety, A.; Han, J.H.; Huh, H.G.; Haque, A.; Hwang, Y.S.; Hyun, H.J.; Jeon, H.B.; Jeon, J.A.; Jeong, S.; Kang, S.C.; Kim, H.J.; Kim, K.C.; Kim, M.H.; Lee, H.Y.; Lee, J.; Lee, M.H.; Lu, L.; Lundquist, J.P.; Lutz, L.; Menchaca-Rocha, A.; Ofoha, O.; Park, H.; Park, I.H.; Park, J.M.; Picot-Clemente, N.; Scrandis, R.; Seo, E.S.; Smith, J.R.; Takeishi, R.; Walpole, P.; Weinmann, R.P.; Wu, H.; Wu, J.; Yin, Z.; Yoon, Y.S.; Zhang, H.G. | Inst. for Phys.

| ○ | Conference paper | Study on environmental thermal induced error modelling of a stage based on artificial neural network | There are many studies on the displacement error of a stage caused by the internal heat source, but only few studies have been done on the error caused by the external heat source. The displacement error caused by the external heat source called environmental thermal induced error occurs when the stage is affected by the temperature change of the environment due to the external heat source. In order to reduce that error, a method of maintaining a constant environmental temperature has been proposed, but in general working environment, it is difficult to completely control the environmental temperature and error due to various external heat sources. Therefore, the effect of the environmental temperature change on the error of the stage should be analysed first. In this study, we propose a method to model and analyse the environmental thermal induced error of the stage using the artificial neural network(ANN). Several thermal sensors are used to measure the temperature of environment and stage, and a measurement system is used to measure the displacement error of the stage. The above-mentioned measurement process is performed according to the time interval, and an artificial neural network-based error model is established using the measurement data. The proposed model can be applied to evaluate the precision of various stages. © European Society for Precision Engineering and Nanotechnology, Conference Proceedings - 22nd International Conference and Exhibition, EUSPEN 2022.

| ○ | Article | Study on Improvement of Catheter Tip Forming Process according to Plating Characteristics in Mold; [금형 내 도금특성에 따른 카테터 팁 성형 공정 개선] | Catheter tip forming is processing the tip at the distal end so that catheter can move smoothly through the geometrically complex vascular structure. This thermoforming process has a problem in that the polymer tube adheres to the outer surface of the mold. To resolve this problem, previous researchers have coated the outer surface of the mold with PTFE (Polytetrafluoroethylene), which has a low coefficient of friction. However, due to repeated use, the coating is detached and the polymer tube adheres to the mandrels again, and the mold is frequently replaced. Thus, in this study, three types of metal were electroplated on the surface of the mold in to realize the performance of the PTFE coating. To select the optimal plating material, Cr, Zn, and Ni were selected as candidate groups. Surface energy, adhesion force, and abrasion depth & volume were measured for performance comparison. As a result, Ni, which has similar surface properties to PTFE, and the best durability, was selected as the optimal material. Based on these results, we present Ni-plated mold that can replace PTFE.

| ○ | ○ | Proceedings Paper | Study on Machine Learning Models for Tree Partitioning Method of Versatile Video Coding | In this paper, we propose a method using machine learning models to determine necessity of ternary tree (TT) partitioning in versatile video coding (VVC). To reduce the encoding complexity of a multi-type tree (MTT) partitioning in VVC, it is significantly important to early decide whether TT is needed. In this study, we analyze the correlation between the known features and the TT partitioning using extensive video dataset. We present a comparative study on machine learning models that consider the TT decision process as a binary classification problem. The experimental results show that the proposed model achieves higher accuracy than that of the existing model.

| ○ | Article | Study on the Machinability of Cryogenic Milling for Compacted Graphite Iron; [CGI 주철 소재 극저온 밀링 공정 절삭성 분석 연구] | Compacted graphite iron (CGI) has been widely used in the automobile industry because of its good mechanical properties. CGI has better strength as compared to grey iron due to its internal structure. It includes graphite particles, which enhance the adhesion between graphite and iron. However, the material characteristics can negatively affect the machinability. In this study, cryogenic milling was performed for CGI450. It is well known that cryogenic machining is effective in improving the machinability. The process included spraying liquid nitrogen as a cryogenic coolant, and the influences on machinability were experimentally investigated with a focus on the cutting force and surface roughness. When liquid nitrogen was sprayed, the cutting force was slightly increased due to the cold-strengthening effect. On the other hand, surface roughness was dramatically decreased by 44.7% as compared to dry milling because brittleness of work material was increased by cryogenic coolant spraying.

| ○ | Article | Study on the Temperature Dependence of Three-dimensional Graphene Structure by Thermal Chemical Vapor Deposition | The effect of temperature on the synthesis of porous three-dimensional (3D) graphene structures on a foam Ni structure by using thermal chemical vapor deposition (TCVD) was investigated. The porous 3D graphene structure was fabricated by forming multi-layered graphene on the surface of a foam Ni structure as the base frame. The foam Ni structure was synthesized using TCVD at temperatures of 800, 900, 1000, and 1100 °C. After graphene synthesis, the Ni substrates were removed using a chemical etching method. The fabricated 3D graphene structure formed a low-density porous network in which multilayered graphene is connected to each other and has pores of various sizes, as confirmed through various analyses. In addition, it was confirmed that the fabricated 3D graphene structure at a synthesis temperature of 1100 °C was deformed without following the shape of the existing Ni structure. © 2022 The Korean Physical Society.

| ○ | Article | Subflow Blocking Method to Improve Performance of MPTCP in High-Speed Train Environments | MPTCP uses multiple interfaces simultaneously in one device, and it improves the total throughput compared to single TCP. The total data throughput is similarly improved compared to single TCP when MPTCP is applied to the high-speed train environment, but Out-of-Order packets occur more frequently than stationary environment because of LTE signal strength reduction and handover. Therefore, HoL Blocking problems in the MPTCP receive buffer occur frequently, and a phenomenon that temporarily decreases performance compared to a single TCP has been resulted. To solve this problem, we propose an method to improve the total data throughput of MPTCP by temporarily blocking the corresponding subflow during a handover. The proposed subflow blocking method has the disadvantage that it can be applied only in an uplink environment, but it mitigates the performance decrease during handover in NS-3 uplink simulation experiment and the total data throughput increased by up to 10% compared to the regular MPTCP, and Out-of-Order packets decreased by about 10%. © 2022, Korean Institute of Communications and Information Sciences.

| ○ | Article | Surface soil moisture memory using stored precipitation fraction in the Korean peninsula | The concept of soil moisture memory was used as a method for quantifying the function of soil to control water flow, which evaluates the average residence time of precipitation. In order to characterize the soil moisture memory, a new measurement index called stored precipitation fraction (FP(f)) was used by tracking the increments in soil moisture by the precipitation event. In this study, the temporal and spatial distribution of soil moisture memory was evaluated along with the slope and soil characteristics of the surface (0~5 cm) soil by using satellite- and model-based precipitation and soil moisture in the Korean peninsula, from 2019 to 2020. The spatial deviation of the soil moisture memory was large as the stored precipitation fraction in the soil decreased preferentially along the mountain range at the beginning (after 3 hours), and the deviation decreased overall after 24 hours. The stored precipitation fraction in the soil clearly decreased as the slope increased, and the effect of drainage of water in the soil according to the composition ratio of the soil particle size was also shown. In addition, average soil moisture contributed to the increase and decrease of hydraulic conductivity, and the rate of rainfall transfer to the depths affected the stored precipitation fraction. It is expected that the results of this study will greatly contribute in clarifying the relationship between soil moisture memory and surface characteristics (slope, soil characteristics) and understanding spatio-temporal variation of soil moisture. © 2022 Korea Water Resources Association. | Kim, Kiyoung; Lee, Seulchan; Lee, Yongjun; Yeon, Minho; Lee, Giha; Choi, Minha | Soil Moisture and Evapotranspiration Infra Team, Korea Institute of Hydrological Survey, Goyang, South Korea; Department of Water Resources, Sungkyunkwan University, Suwon, South Korea; Soil Moisture and Evapotranspiration Infra Team, Korea Institute of Hydrological Survey, Goyang, South Korea; Department of Advanced Science and Technology Convergence, Kyungpook National University, Daegu, South Korea; Department of Advanced Science and Technology Convergence, Kyungpook National University, Daegu, South Korea; School of Civil, Architecture Engineering & Landscape Architecture, Sungkyunkwan University, Suwon, South Korea | 58163064200; 57213196650; 58163197700; 57223436971; 35069799400; 15848058400 | mhchoi@skku.edu; | Journal of Korea Water Resources Association | 2799-8746 | 55 | 2 | 0 | 2025-06-25 | 0 | Precipitation; Soil moisture; Soil moisture memory; Stored precipitation fraction | Korean | Final | 2022 | 10.3741/jkwra.2022.55.2.111 | 바로가기 | 바로가기 | ||||||||||||||||

| ○ | ○ | Proceedings Paper | Switching-Cell Back-to-Back Current Source Converter with Modified SVPWM | Current source back-to-back converter has some advantage than voltage source back-to-back converter such as using inductor for power decoupling, no shoot-through problem. However, open-circuit problem occurs when there is no path for the inductor current to flow. Therefore, conventional current source rectifier or inverter needs overlap time to prevent open-circuit problem. The overlap time distort waveform of the output current. This study proposed a three-phase switching-cell back-to-back current source converter (SC-CSC). Compared to the conventional current source converter, the SC-CSC has no open-circuit possibility; thus, the converter reliability is greatly enhanced. However, due to the presence of switching-cell capacitors, SVPWM is modified in order to make voltage rating of semiconductor device the same as conventional one. The operating principle and characteristics of the proposed SC-CSC are analyzed in detail. | Hong, Daheon; Cha, Honnyong | Kyungpook Natl Univ, Sch Energy Engn, Daegu, South Korea | 57224204267; 24450248400 | hongda1021@knu.ac.kr;chahonny@knu.ac.kr; | 2022 25TH INTERNATIONAL CONFERENCE ON ELECTRICAL MACHINES AND SYSTEMS (ICEMS 2022) | 0 | 2025-06-25 | 0 | 0 | Back-to-back; current source; space vector; switching-cell; reliability | CURRENT-SOURCE INVERTER | Back-to-back; current source; reliability; space vector; switching-cell | Cells; Cytology; Electric rectifiers; Power converters; Pulse width modulation; Vector spaces; Back-to-back; Conventional currents; Current source converters; Current sources; Open-circuits; Power decoupling; Shoot-through; Space Vector; Switching cells; Voltage source; Semiconductor devices | English | 2022 | 2022 | 10.1109/icems56177.2022.9982857 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Article | Synchrotron X-Ray Diffraction Studies on Crystalline Domains in Urea–Formaldehyde Resins at Low Molar Ratio | The crystalline domain of thermosetting urea–formaldehyde (UF) resins at low formaldehyde-to-urea (F/U) molar ratios (≤ 1.0) is known to be responsible for their poor performance as wood adhesives. Crystallization has been observed in 1.0 F/U UF resins during the addition reaction stage and at the end of the synthesis process (neat UF resins). The crystallinity and X-ray diffraction (XRD) spectra of the uncured neat UF resins, on the other hand, differed significantly from those of the cured neat UF resins, raising the possibility that their crystal structures were also different. This study demonstrates for the first time that the crystalline domains in 1.0 F/U UF resins generated from uncured and cured samples are identical. Despite having a lower crystallinity value, the synchrotron XRD patterns of purified neat UF resins were equivalent to the XRD patterns of cured neat UF resins. Transmission electron microscope images of the cured UF resins showed that the crystals were lamellar structures. This finding suggests that the crystal at low molar ratio UF resins are isotropic polycrystals with random orientation. © 2022, Korean Society of Wood Science Technology.

| ○ | ○ | Article | Synthesis and characterization of graphene quantum dot/SiNP/carbon nanomaterial composites | We have used graphene quantum dots (GQDs), silicon nanoparticles (SiNPs) and carbon nanomaterials to synthesize GQD/SiNP/carbon nanofibers (CNFs) and GQD/SiNP/carbon nanotubes (CNTs) composites, which can improve the low charging capacity of carbon materials. To fabricate these composites, we positively charged SiNPs by adding poly(diallyldimethylammonium chloride) (PolyDADMAC). Subsequently, we combined positively charged SiNPs with hydroxyl-attached GQDs (OH-GQDs) using electrostatic attraction followed by mixing and dispersing GQD/SiNP nanocomposites with CNFs or CNTs, respectively. Then, they were reduced through annealing under Ar/H-2 gases. The obtained OH-GQDs had a diameter of 5.75 nm on average, a standard deviation of 0.74, and a lattice spacing of 0.21 nm. The manufactured materials were characterized with Scanning Electron Microscopy (SEM)/Energy Dispersive Spectroscopy (EDS), Transmission Electron Microscopy (TEM), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), and Raman Spectroscopy to investigate their physical properties. We expect that these composites can be applied as various devices such as Li ion batteries, semiconductor, display, bio kit, and image sensors, by complementing each component deficiencies. | Kwon, Sera; Jamal, Hasan; Choi, Jin-Yeong; Park, Hyun-Ho; Song, Jubeom; Lee, Chang-Seop | Keimyung Univ, Dept Chem, Daegu 42601, South Korea; Kyungpook Natl Univ, Dept Chem Educ, Daegu 41566, South Korea | Jamal, Hasan/GNO-9249-2022; Lee, Chang-Seop/IQU-1791-2023 | 57941880900; 57222123834; 57071954600; 59110485800; 57221558747; 57207257491 | surfkm@kmu.ac.kr; | APPLIED NANOSCIENCE | 2190-5509 | 2190-5517 | 12 | 11 | 0.55 | 2025-06-25 | 5 | 6 | Graphene quantum dots; Silicon; Carbon nanofibers; Carbon nanotubes; Composite | LITHIUM-ION BATTERIES; HIGH-CAPACITY; NANOTUBE COMPOSITES; CARBON NANOFIBERS; PERFORMANCE; DOTS; ANODE; ELECTRODE; SI | Carbon nanofibers; Carbon nanotubes; Composite; Graphene quantum dots; Silicon | Carbon nanotubes; Chlorine compounds; Fourier transform infrared spectroscopy; Graphene; High resolution transmission electron microscopy; Lithium-ion batteries; Nanocrystals; Scanning electron microscopy; Semiconductor quantum dots; Synthesis (chemical); X ray photoelectron spectroscopy; Carbon material; Carbon nano-materials; Carbon nanofibres; Carbon nanotubes composites; Poly (diallyldimethylammonium chloride); Polydiallyldimethyl ammonium chloride; Positively charged; Silicon carbon; Silicon nanoparticles; Synthesis and characterizations; Silicon | English | 2022 | 2022-11 | 10.1007/s13204-022-02676-3 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | Synthesis of AA8050/B4C/TiB2 Hybrid Nanocomposites and Evaluation of Computer-Aided Machining Parameters | This research focusses on synthesizing the hybrid nanocomposite samples with AA8050 and the reinforcement of B4C and TiB2 nanoparticles at 3 different quality grades. To investigate their machinabilities on the prepared composites in the computer-aided machining centre, the objectives are maximizing the material removal rate (MRR) and minimizing the surface roughness for a specific application. Stir casting process was employed in synthesizing the hybrid nanocomposite samples. Utilizing CNC turning centre was employed to investigate machinability performance on hybrid nanocomposite samples. The PVD-coated HSS tool and dry cutting environment were considered. The quality of machining was investigated by observing the surface roughness on the machined surfaces of samples of hybrid nanocomposite. The machining rate was investigated through the response of material removal rate at as per Taguchi design of experiments L27 orthogonal array. The hybrid nanocomposite synthesizing parameter of contribution of nanoparticle reinforcement (8%, 10%, and 12%) and the Turing parameters include spindle speed (800 rpm, 1000 rpm, and 1200 rpm), machining feed (0.05 mm/rev, 0.10 mm/rev, and 0.15 mm/rev) and depth of cut (0.5 mm, 0.75 mm, and 1 mm). The best performing input levels were identified through Taguchi analysis and the involved input variables were analysed and prediction model developed through ANOVA. The maximum material removal rate and the minimum surface roughness were reordered as 1380mm(3)/min. | Sathish, T.; Vinayagam, Mohanavel; Raja, T.; Seikh, A. H.; Siddique, M.
