Article New Records of Two Unreported Fungal Species: Cladophialophora floridana and Chloridium setosum Isolated from Soil in Korea During an exploration of fungal diversity in Korean soil, this study isolated two fungal strains, designated KNUF-23-321L and KNUF-23-314, and identified them as previously unrecorded species. Morphological and cultural features were examined for initial classification. The characteristics of strains KNUF-23-321L and KNUF-23-314 matched those of Cladophialophora floridana SR3028T, and Chloridium setosum CGMCC 3.20741T, respectively. To further pinpoint their identities and evolutionary relationships, molecular phylogenetic analyses were conducted using the internal transcribed spacer (ITS) regions and 28S rDNA large subunit (LSU) on strain KNUF-23-321L which showed high similarity of 98.6 and 100%, respectively, with strain C. floridana SR3028T. For the strain KNUF-23-314, it showed a high similarity of 100% with strain Ch. setosum CBS 263.76A with both ITS regions and LSU genes. These combined morphological and phylogenetical analyses revealed that KNUF-23-321L was identified as C. floridana, and KNUF-23-314 was identified as Ch. setosum. To the best of our knowledge, these are the first reports of C. floridana and Ch. setosum in Korea. © 2024 THE KOREAN SOCIETY OF MYCOLOGY.

Conference paper Nine-Depth Switchable Augmented Reality Display with Bi-stacked Quarter-Waveplate-Based Geometric Phase Lenses Here, we present triple sets of wavefront modulation by proposing quarter-waveplate-based GPL (QWP GPL). We demonstrate nine depth-switchable AR imaging functions with a bi-stack condition of the QWP GPL modules. The presented QWP-based GPL module scheme is advantageous for increasing depth-switchable layers without increasing the switchable optic units required. In addition, the AR display optics based on the QWP GPL module can further improve form-factor issues and AR imaging properties. © 2024, John Wiley and Sons Inc. All rights reserved.

Conference paper NODE and Contraction Methods for Dynamics Learning from Human Expert Demonstrations In this paper, we propose model-free or learning-from-demonstration methodologies for accurately estimating the complex and nonlinear behaviors of dynamic systems such as mobile robots, robotic arm manipulators, and unmanned aerial vehicles (UAVs). Under learning from demonstration (LfD), this study investigates two different approaches: The first proposed methodology is the contraction theory, in which the assigned task demonstration is practically performed by the human expert, who tries to learn and imitate it. On the other hand, the same task learns and imitates by utilizing the neural ordinary differential equations (NODEs) for dynamic systems. Using the concepts of both approaches, we tried to make it possible for the system to pick up on and imitate the shown behavior or demonstration accurately. In dynamics learning, the proposed contraction method utilizes the conceptual framework of the contraction theory, which ensures the motions of dynamic systems that eventually converge to nominal or desired behavior. At the same time, NODE uses the neural network with different configurations of hidden layers, learning rate, nonlinear activation function, and ODE solver. A spiral trajectory is considered a human expert demonstration that is estimated by both methodologies (i) NODE and (ii) contraction theory. For validation purposes, we compared the results of both approaches. © 2024 by SCITEPRESS-Science and Technology Publications, Lda. Ahmed, Tufail; Lee, Sangmoon; Park, Ju H.

Conference paper Non-Calibration Sensor Fusion Using High Resolution 3D LiDAR Light detection and ranging (LiDAR) and camera are the most commonly used combination in sensor fusion techniques. In this paper, we propose a method to recognize obstacles by fusion of images and point cloud data generated from high-resolution 3D LiDAR. By applying the image to a deep learning network, we obtain inference information about the obstacle, and based on this, we convert the pixel location of the obstacle in the image into a mapped point cloud. This enables more sophisticated obstacle recognition by converting 2D data into 3D space data. The algorithm is implemented in an autonomous vehicle and tested at the proving ground of the Korea Intelligent Automotive Parts Promotion Institute (KIAPI), under the 2024 autonomous driving competition for university students, Daegu, Republic of Korea © 2024 IEEE.

Article Non-destructive morphological screening for the assessment of postharvest storage effect on pears stored with apples using optical coherence tomography The use of a limited and inadequate storage facility for the storage of multiple food items for an extended period of time results in the loss of structural integrity and freshness while storing fruit in confined single storage without adequate individual packaging methods can result in morphological changes and the degradation of the quality of the fruit. In this study, the effects of postharvest storage on pears co-stored with apples were investigated via non-invasive screening of the structural deformation of pears and the respective anatomical changes of the sub-surface. The anatomical changes were monitored for a prolonged time (12 d) under inadequate and confined storage conditions using swept-source optical coherence tomography (SS-OCT) and the results were comparatively analyzed using appropriately stored specimens. In addition, the OCT cross-sectional images were analyzed for the assessment of the dispersed intensity profile using a customized intensity-based image-processing algorithm. The results revealed the internal morphological variations and corresponding intensity fluctuations, thickness variations, and internal gap formations. This confirmed the potential applicability of OCT as a real-time, non-invasive high-resolution assessment technique for determining fruit quality in diverse environments, such as post-harvest storage and transportation systems. © 2024 Elsevier GmbH Luna, Jannat Amrin; Wijesinghe, Ruchire Eranga; Lee, Seung-Yeol; Ravichandran, Naresh Kumar; Saleah, Sm Abu; Seong, Daewoon; Jung, Hee-Young; Jeon, Mansik; Kim, Jeehyun School of Electronic and Electrical Engineering, College of IT Engineering, Kyungpook National University, 80, Daehak-ro, Buk-gu, Daegu, 41566, South Korea; Department of Electrical and Electronic Engineering, Faculty of Engineering, Sri Lanka Institute of Information Technology, Malabe, Sri Lanka; School of Applied Biosciences, Kyungpook National University, 80, Daehak-ro, Buk-gu, Daegu, 41566, South Korea; Center for Scientific Instrumentation, Korea Basic Science Institute, 169-148, Gwahak-ro Yuseong-gu, Daejeon, 34133, South Korea; ICT Convergence Research Center, Kyungpook National University, Daegu, 41566, South Korea; School of Electronic and Electrical Engineering, College of IT Engineering, Kyungpook National University, 80, Daehak-ro, Buk-gu, Daegu, 41566, South Korea; School of Applied Biosciences, Kyungpook National University, 80, Daehak-ro, Buk-gu, Daegu, 41566, South Korea; School of Electronic and Electrical Engineering, College of IT Engineering, Kyungpook National University, 80, Daehak-ro, Buk-gu, Daegu, 41566, South Korea; School of Electronic and Electrical Engineering, College of IT Engineering, Kyungpook National University, 80, Daehak-ro, Buk-gu, Daegu, 41566, South Korea 58079161200; 56018152300; 56106499600; 57125825900; 57218499446; 57212512353; 7403029383; 24171094000; 7601373350 heeyoung@knu.ac.kr; Optik 0030-4026 301 0.76 2025-05-07 2 Morphological screening; Optical coherence tomography; Optical imaging; Postharvest storage effect; SS-OCT Food storage; Fruits; Optical data processing; Real time systems; Anatomical changes; Morphological changes; Morphological screening; Non destructive; Optical imaging; Packaging methods; Post-harvest storage; Postharve storage effect; Storage facilities; Swept source optical coherence tomographies; Optical tomography English Final 2024 10.1016/j.ijleo.2024.171678 바로가기 바로가기
Proceedings Paper Non-Functional Requirements Discovery and Quality Assurance using Goal Model for Earthquake Warning System in Operation Many industrial systems that are developed without proper engineering guidance due to a lack of expertise or resources suffer from failures and maintenance problems in their evolving lifecycle. For mission-critical systems, in particular, ensuring high quality of non-functional requirements in a rapidly changing domain environment is of the utmost importance. In this paper, we report our case study with an industry system, a sensor-based earthquake warning system that was developed without a rigorous engineering process. Therefore, no requirements documents are available for future maintenance and verification. In this study, we used various types of software analysis methods such as stakeholder interviews, document reviews, source code analysis, model checking, and software testing for discovering requirements and also for verification purposes. We used a goal modeling approach to gather a set of initial requirements as though they had been elicited using an appropriate requirements engineering method in the early stage of the development process. Furthermore, software testing and model checking were iteratively used to verify and clarify unknown-source, uncertain, and unconfirmed requirements during the revision of the goal model. This study also provides an architectural improvement of the system through the discovery of requirements conflicts and violations. The experience and findings of this study, which demonstrate the effectiveness of applying diverse software engineering techniques in maintenance, can contribute to the analysis and evolution of systems developed without a proper engineering process, by discovering and verifying some critical requirements specifications.

Article Non-Terrestrial Networks: An Overview of 3GPP Release 17 & 18 This article provides an overview of technological advancements in Non-Terrestrial Networks (NTN) from the perspective of the 3rd Generation Partnership Project (3GPP). With the introduction of 3GPP Release 17 & 18, there has been a significant emphasis on integrating satellite access networks into terrestrial networks. This integration necessitates a holistic design approach that spans multiple areas, including the Radio Access Network (RAN) to services and system aspects to core, and terminals. The article provides insights and implications of incorporating satellite access networks as a new 3GPP RAN and as a backhaul solution. We explore the impact of this integration on network architecture and performance, considering factors such as coverage, capacity, and latency. The article also highlights the key issues in 3GPP Release 18 and outlines the prospective potential solutions in the context of NTN to support 5G and beyond integrated architecture. Additionally, the article discusses the enhancements made in 3GPP Release 18 to support 5G and beyond in the context of Uncrewed Aerial Vehicles (UAVs). © 2024 Institute of Electrical and Electronics Engineers Inc..

Proceedings Paper Nonlinear Model Predictive Control Approximation: Applications to Truck-Trailer Control System In this work, we demonstrate the effectiveness of nonlinear model predictive control (NMPC) approximation based on deep neural network (DNN). MPC has been widely adopted in autonomous driving control problems to handle multiple objectives and constraints. We first design the implicit NMPC for the forward and backward motions of a truck-trailer (TT) system, which follows the reference path while maintaining safety between the head truck (HT) and the trailer (TR). However, the computational load in implicit MPC makes it a challenge for real-time implementations. To alleviate the computational burden in implicit NMPC online, an NMPC approximation approach based on DNN is adopted in this study to achieve a parametric function approximation. We conduct a comparative study on the proposed approach and a baseline controller for control performance analysis, and the computational load is evaluated on a hardware-in-the-loop (HIL) experimental system.

Proceedings Paper NORNS: Three Guides for Efficient Automatic Post-Fabrication Optimization of Modern NAND Flash Memory In order to meet the diverse requirements of modern storage systems, flash memory should be optimized by precisely tuning a huge number of internal operating parameters. Although 3D NAND flash memory successfully increases the capacity of storage systems, its complex architecture and unique error behavior make such optimization a more difficult and time-consuming process during NAND manufacturing. This work introduces NORNS, a novel method for post-fabrication optimization of NAND flash memory, which is an essential step in the manufacturing process of modern 3D NAND flash memory to simultaneously meet various requirements on reliability, performance, yield, etc. NORNS is based on simple machine-learning approaches yet with three key guidelines that leverage (i) domain-specific rules, (ii) recent optimization results, and (iii) online simulation, respectively, to enable quick optimization of a large number of device parameters within the limited product turnaround time (TAT). We evaluate NORNS in mass production for 7th-generation QLC NAND flash memory and 8th-generation TLC NAND flash memory. Our NORNS can achieve superior optimization over existing post-fabrication optimization techniques by showing significant performance and reliability improvements by up to 8.8% and 12% on average, respectively.

Article Notable mutations of porcine parvovirus 1 and 4 circulating in commercial pig farms in South Korea In this study, almost complete genomic sequences of porcine parvovirus (PPV)1 and PPV4 circulating in commercial pig farms in South Korea were obtained and analyzed. Important mutations that may be precursors to host changes, such as premature stop codons of PPV1 and frameshift mutations of PPV4, were observed in these sequences. A 27a-like strain of PPV1, known to show a lack of cross- neutralization against existing commercial vaccine strains, was identified by phylogenetic analysis.

Proceedings Paper Novel Design Optimization Strategy using a Lumped Magnetic-Circuit Model for Surface Permenet Magnet Machine with Step-skewing Rotor In this paper, a novel approximation strategy to three-dimensional(3-D) optimization design is proposed for surface permanent-magnet machines (SPMSM) with rotor overhang and step-skewing type motor using lumped magnetic circuit model. The rotor overhang method is applied to consider the tolerance of electric steel length in axial-direction and maintain the machine performances. The rotor step-skewing technique is used to reduce cogging torque, torque ripple value and THD of back-electro motive force (EMF). In general, the 3-D finite element method (FEM) analysis is requisite to analyze the performance of overhang and step-skewing SPM motor considering the additional flux on the overhang side and the leakage flux crossing section on the rotor magnet side. Moreover, to optimize the SPM topology for target performance, 3-D effect which are number of skew steps, shape of magnet and length of rotor, need to be considered. However, 3-D FEM optimization process requires abundant computation time and computing memory. To deal with this problem, main design variables is considered using lumped magnetic-circuit model. In addition, effective of this method is validated through comparison of 2-D, 3D and test results.
