| ○ | Conference paper | A Close Look at Shared Resource Consumption in NoSQL Databases for Accurate Accounting | A NoSQL database plays an essential role in all parts of today's multi-tenant large-scale IT services. Accurate information about per-tenant resource accounting is invaluable for optimal service management. However, there is a lack of study on the characteristics of resource consumption by multi-tenants in NoSQL database services, particularly for those resources consumed as part of activities asynchronously triggered by requests accumulated over time from multiple tenants. According to our investigation, this shared resource usage takes up a significant portion of total resource consumption in NoSQL databases.We assert that an accurate understanding of the shared resource consumption pattern is required to design correct and effective techniques for resource management. To this end, we conduct a detailed investigation of the shared resource consumption in popular NoSQL databases. Our focuses are to find out what portion of the overall resource consumption occurs in a shared manner, what type of operations cause them, and what effect the workload intensity has on the amount of shared resource consumption. We have developed a set of techniques for monitoring, recording, and analyzing the resource consumption data toward answering these questions. Our investigation revealed that the shared resource consumption can be as large as 30% of the total resource consumption, implying that resource accounting based only on directly causal events, may lead to underestimation of the true amount. We believe our study highlights the importance of shared resource accounting and provides crucial insights for building accurate resource accounting techniques. © 2023 IEEE. | Lee, Jaeryun; Tak, Byungchul; Seo, Euiseong | Kyungpook National University, School of Computer Science and Engineering, Daegu, South Korea; Kyungpook National University, School of Computer Science and Engineering, Daegu, South Korea; Sungkyunkwan University, Dept. of Computer Science and Engineering, Suwon, South Korea | 57773643900; 6506911621; 14056969000 | bctak@knu.ac.kr; | Proceedings of IEEE/IFIP Network Operations and Management Symposium 2023, NOMS 2023 | 0 | 2025-06-25 | 0 | NoSQL database; Resource accounting; Shared resource | Information management; Accounting IS; Database service; IT services; Large-scales; Multi tenants; NoSQL database; Resource accountings; Resources consumption; Service management; Shared resources; Database systems | English | Final | 2023 | 10.1109/noms56928.2023.10154320 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Book chapter | A Combined Scheduling and Simulation Method to Analyze the Performance of the Dual-Robot In-Line Stocker | The in-line stocker is a new type of the automated material handling system that has begun to be used in the display industry. This not only moves unit loads under processing across different locations within manufacturing facilities, similar to the automated guided vehicle (AGV), but also stores them on its shelves, similar to the automated storage and retrieval system (ASRS), which can significantly reduce space for material handling. However, traffic rates are generally very high inside the in-line stocker and two robots serve along the single lane, which is the dual-robot in-line stocker (DRIS). One difficulty in applying the DRIS to shop floors is that the exact transport capacity of the unit DRIS is not known. This paper develops an analytical model to estimate the capacity of the DRIS based on a combined scheduling and simulation method. It calculates movements of two robots over time in the space consisting of time and location and precisely measure necessary time for waiting or backtracking to avoid collision of two robots. An experimental analysis was conducted to validate the correctness and usefulness of the model based on the data used in an actual manufacturing site. The analysis result illustrates that the average processing capacity of the DRIS increases compared to the SRIS (single robot in-line stocker) as the length of the DIRS increases, which is consistent with the expectation of practitioners in the industry. The paper also verifies that it is necessary to carefully determine the operating specifications in actual uses since the transport capacity of the DIRS varies considerably by its operating parameters, which can be optimized by the analytical model. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG. | Chung, Jaewoo | Department of Operational Management, School of Business Administration, Kyungpook National University, Daegu, South Korea | 55470448800 | chung@knu.ac.kr; | Lecture Notes in Production Engineering | 2194-0525 | Part F1164 | 0.95 | 2025-06-25 | 1 | Automated material handling system; Dual-robot AS//RS; In-line stocker; Scheduling and simulation; Simulation modeling | Analytical models; Automatic guided vehicles; Automation; Digital storage; Automated material handling systems; Display industry; Dual robots; Dual-robot AS//RS; In-line stocke; Manufacturing facility; Performance; Scheduling and simulation; Simulation-modelling; Transport capacity; Materials handling | English | Final | 2023 | 10.1007/978-3-031-18641-7_21 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Proceedings Paper | A Compact Q-Learning-Based Standard Cell Layout Compiler for 3nm GAAFET and Beyond | In the latest technology nodes with complex design rules, it becomes highly-challenging to design standard cells (SDCs) by hand. To overcome this challenge, many studies have announced fully-automated SDC compilers for advanced nodes. However, previous studies cannot design SDCs that are beyond certain number of transistors or were requiring too expensive computing resources. Therefore, this paper provides highly compact Q-learning-based SDC compiler that 1) overcomes transistor count limitation of SDC design, and 2) can design SDCs (training and inferencing) on normal computing systems in less than day. In addition to 100% successful SDC designs, our SDC compiler optimizes the layout area of the most complex cell by up to 36.67% in the 3 nm technology node. | Shin, MinSeung; Kim, Jongbeom; Shin, Yunjeong; Song, Taigon | Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea | 58882354300; 57782068500; 58882495300; 36005021000 | helium990315@knu.ac.kr;tsong@knu.ac.kr; | 2023 20TH INTERNATIONAL SOC DESIGN CONFERENCE, ISOCC | 2163-9612 | 0 | 2025-06-25 | 0 | 0 | Standard Cell Design; EDA; Reinforcement Learning | EDA; Reinforcement Learning; Standard Cell Design | Cells; Cytology; Program compilers; Can design; Cell layout; Design standard; EDA; Latest technology; Q-learning; Reinforcement learnings; Standard cell design; Standard-cell; Technology nodes; Reinforcement learning | English | 2023 | 2023 | 10.1109/isocc59558.2023.10396096 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Article | A comparative analysis of in vivo toxicity, larvicidal and catalytic activity of synthesized silver nanoparticles | In this study, mosquito larvicidal, photocatalytic activities and in vivo biocompatibility in Wistar rats studies of synthesized silver nanoparticles (AgNPs) from Acacia nilotica (An) and its purified compound pyrogallol (Py) were examined. In in vivo studies, rats in various groups were administrated intraperitoneal injection with 20 and 40 mg/kg body weight (BW) of An-AgNPs and Py-AgNPs for 14 days for once in a day. Histology analysis of major organs, such as liver, kidney, spleen, lung, and heart, indicates normal structure at particular doses of An-AgNPs and Py-AgNPs; however, 40 mg/kg BW of An-AgNPs showed lower toxicity level. An-AgNPs and Py-AgNPs showed good larvicidal activity against Culex quinquefasciatus (C. quinquefasciatus) and Aedes aegypti (A. aegypti) and showed good photo-catalytic activity against methylene blue (MB) dye. However, An-AgNPs showed higher (82.93%) catalytic activity in 150 min. Thus, the present study will support the use of synthesized Py-AgNPs in the future in vivo applications, and An-AgNPs may act as a water pollution-controlling agent. © 2021, King Abdulaziz City for Science and Technology. | Sampath, Gattu; Govarthanan, Muthusamy; Rameshkumar, Neelamegam; Krishnan, Muthukalingan; Alotaibi, Saad H.; Nagarajan, Kayalvizhi | Department of Zoology, School of Life Sciences, Periyar University, Tamil Nadu, Salem, 636 011, India; Department of Environmental Engineering, Kyungpook National University, Daegu, 41566, South Korea; School of Life Sciences, Central University of Tamil Nadu, Tamil Nadu, Thiruvarur, 610005, India; Central University of Tamil Nadu, Tamil Nadu, Thiruvarur, 610005, India; Department of Chemistry, Turabah University College, Taif University, P.

| ○ | ○ | Review | A comprehensive review of difficult airway management strategies for patient safety | Difficult airway management is critical to ensuring patient safety. It involves addressing the challenges and failures that can occur, even with skilled healthcare providers, during face mask ventilation, intubation, supraglottic airway placement, invasive airway procedures, or extubation. Although the incidence of the most critical situation in airway management, "cannot intubate, cannot oxygenate," is low at 0.0019-0.04%, its occurrence can have severe consequences, including dental injury, airway injury, hypoxic brain damage, and even death. This study aimed to offer healthcare providers a comprehensive and evidence-based approach for difficult airway management by reviewing recent guidelines and incorporating the latest evidence-based practices to improve their preparedness and competence in difficult airway management, and thus ultimately contribute to improved patient safety. | Jung, Hoon | Kyungpook Natl Univ, Sch Med, Dept Anesthesiol & Pain Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea | 55967121200 | wing2392@naver.com; | ANESTHESIA AND PAIN MEDICINE | 1975-5171 | 2383-7977 | 18 | 4 | 1.45 | 2025-06-25 | 9 | 9 | Airway management; Airway obstruction; Cricothyroidotomy; Face mask ventilation; Intubation; Supraglottic airway; Ventilation | TRACHEAL INTUBATION; SOCIETY GUIDELINES; PREDICTORS | Airway management; Airway obstruction; Cricothyroidotomy; Face mask ventilation; Intubation; Supraglottic airway; Ventilation | English | 2023 | 2023-10 | 10.17085/apm.23123 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | A Convenient Calibration of a 3D Foot Scanning System using a Solid Paper Object | In this study, a new method is proposed for developing an effective calibration object by using commonly available papers. The proposed method uses a pyramid-shaped solid paper as a calibration object for foot scanners with two sensors. The design of this calibration object allows simultaneous scanning of its inner and outer surfaces. The three-dimensional (3D) shape information collected from the two sensors is used to derive an initial 3D transformation relationship between the two sensors. Next, the intersections between the four facets of the pyramid-shaped object are used in conjunction with a minimization algorithm to improve the precision of the 3D transformation relationship. The proposed method is applied to an actual foot scanning system to calibrate the upper and lower 3D sensors of the foot scanner, and the 3D model is reconstructed. The performance of this method is verified by comparing the reconstructed models with ground truth models. The calibration error between the two sensors was less than 0.6 mm on average when using the proposed calibration method. The proposed method offers the advantage of simple operation as it uses a single sheet of paper, thus avoiding the difficulties encountered in conventional calibration methods. © ICROS 2023. | Lee, Ju-Whan; Baek, Seung-Hae; Park, Soon-Yong | School of Electronic and Electrical Engineering, Kyungpook National University, South Korea; LS-Swift Division, KLA, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University, South Korea | 58205426000; 48861235500; 7501834063 | sypark@knu.ac.kr; | Journal of Institute of Control, Robotics and Systems | 1976-5622 | 29 | 4 | 0 | 2025-06-25 | 0 | 3D reconstruction; foot scanning system; ICP; paper object calibration | 3D modeling; Image reconstruction; Imaging systems; Paper; Three dimensional computer graphics; 3D reconstruction; 3D transformations; Calibration method; Foot scanner; Foot scanning system; ICP; Inner surfaces; Outer surface; Paper object calibration; Scanning systems; Calibration | English | Final | 2023 | 10.5302/j.icros.2023.22.0227 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Article | A Damping Compensation Method for Suppressing Vibration in a Transient State in a Turret Servo System of a Machine Tools with Low Inertia; [저 관성을 가지는 공작기계의 터렛 서보 시스템에서 과도상태의 진동억제를 위한 댐핑 보상기법] | In general, rotor inertia has an inversely proportional relationship with proportional gain and bandwidth in a turret speed control system of machine tools; thus, this system has a disadvantage, such as weak disturbance caused by a decrease in the damping ratio and an increase in bandwidth due to low rotor inertia. This paper proposes a damping compensator that is resistance to disturbances in order to improve the above problems. The proposed damping compensator reduces the residual vibration induced in the transient state by using a digital high-pass filter. The experimental results showed that the overshoot was reduced by about 5.5% in the speed response and by about 20% in the torque response in the no-load condition. Under the load condition of 4.8 N.m, the torque response showed that the undershoot was reduced by about 26%.

| ○ | Conference paper | A FMI-based Approach for CAN Bus Simulation and Simulink Model Integration in Vehicle Simulation Environment | Automotive software is becoming more complex and diverse, making the development and verification process more important. However, the existing integrated simulation environment does not reflect the characteristics of CAN communication that can occur in the real vehicle environment. In this paper, we propose a Functional Mock-up Interface (FMI) 2.0-based approach to build an integrated simulation environment that includes a CAN bus. We design and implement a CAN Bus Simulation (CBS) FMU model that can simulate CAN communication among various models of vehicle systems, and an FMI CAN Function Module that can make Simulink models compatible with CAN communication. We also integrate the developed models into the MasterSim simulation environment and verify that the data exchange between the models is performed correctly. Our approach has several advantages over the existing methods. First, it supports various models and tools that comply with the FMI 2.0 standard. Second, it can simulate the actual operation of the CAN bus such as message transmission time and priority, and evaluate the impact of these factors on system performance. Lastly, it preserves the original structure and function of Simulink models and requires only minimal modifications to support CAN communication. © 2023 IEEE. | Kim, Hyeongrae; Lee, Harim; Cho, Jeonghun | Kyungpook National University, School of Electronics and Electrical Engineering, Daegu, South Korea; Kyungpook National University, School of Electronics Engineering, Daegu, South Korea; Kyungpook National University, School of Electronics Engineering, Daegu, South Korea | 57203064517; 58875678400; 7403536198 | hrsin95@knu.ac.kr; | International Conference on ICT Convergence | 2162-1233 | 0.43 | 2025-06-25 | 1 | automotive embedded software; CAN simulation; Functional Mock-up Interface; Simulink; virtual ECU | Electronic data interchange; Mockups; Vehicle to vehicle communications; Vehicles; Verification; Virtual reality; Automotive embedded software; Automotives; CAN bus; CAN communications; CAN simulation; Functional mock-up interface; Mock up; Simulink; Simulink models; Virtual ECU; Simulink | English | Final | 2023 | 10.1109/ictc58733.2023.10393858 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | Article | A Graphics Device Driver Implementation Compliant with OpenGL SC 2.0.1 Standard Specification | Various 3D graphics outputs are increasingly required in the field of safety-critical applications including military, avionics, aerospace, and medical applications. In this paper, we present a graphics device driver implementation of OpenGL SC (Open Graphics Library – Safety Critical) 2.0.1, a 3D graphics standard specification that reflects the needs of the safety-critical field. OpenGL SC 2.0.1 was newly announced in 2019, and only a few limited number of implementation cases have been reported so far. In this paper, to increase its own portability, we designed to only use some functions of DRM (direct rendering manager) in a general Linux environment, while various test results were confirmed targeting specific GPUs, in our case, Intel HD630 GPU. The implementation results can be used to implement 3D graphics terminals in the military and aviation fields. © 2023, Roman Science Publications and Distributions.

| ○ | Conference paper | A Lightweight Seamless Authentication Scheme for Edge-Assisted IoV networks | Internet of vehicles (IoV) is an expanded concept of vehicular ad-hoc networks (VANET), and it is more scalable and can be combined with the latest mobile communication technology such as 5G and 6G. The IoV environment aims to realize autonomous driving through communication such as vehicle-to-infrastructure (V2I), vehicle-to-vehicle (V2V), and vehicle-to-person (V2P). Among them, V2I interaction is the most basic communication. In IoV environments, vehicles have mobility, and it is very frequent to authenticate with the same RSU or another RSU after authenticating with a RSU in its first region. If the authentication process is repeated in re-authentication situations, it can put a burden on the vehicle and RSU and have negatively the performance of the network. In this paper, we proposed authentication protocols considering three situations: Initial authentication, re-authentication, and handover authentication. We demonstrate that our scheme has resistance to various attack scenarios, and compared the performance of the proposed scheme with existing schemes. © 2023 IEEE. | Son, Seunghwan; Kim, Myeonghyun; Park, Youngho | Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea; Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea; Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea | 57221744477; 57210278739; 56962990300 | parkyh@knu.ac.kr; | International Conference on Ubiquitous and Future Networks, ICUFN | 2165-8528 | 2023-July | 1.49 | 2025-06-25 | 3 | chaotic-map; edge computing; handover authentication; Internet of vehicle; re-authentication | 5G mobile communication systems; Authentication; Chaotic systems; Edge computing; Vehicle to vehicle communications; Vehicular ad hoc networks; Authentication scheme; Chaotic map; Edge computing; Handover authentications; Internet of vehicle; Mobile communication technology; Performance; Re authentications; Vehicle network; Vehicular Adhoc Networks (VANETs); Vehicles | English | Final | 2023 | 10.1109/icufn57995.2023.10200823 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Conference paper | A Method for Reducing Simulation Timing Deviation in QEMU-Based Virtual ECU | As support for a wider range of functions and services of vehicles, such as driver assistance systems, autonomous driving, and OTA services, has increased in recent years, the complexity of software embedded in vehicles has become increasingly complex. These changes are driving demand for simulation technologies that can help reduce development and validation time while ensuring vehicle safety and reliability. Among them, electronic control unit virtualization technology is steadily being researched and commercialized by many companies because it can consider the characteristics of ECUs from the development and validation stages of in-vehicle embedded software. In this paper, we discuss the virtualization method of STM32F407ZGT using QEMU as part of ECU virtualization technology. Furthermore, we propose a technique to reduce the simulation error by measuring the running time of the physical ECU and adjusting the unit time in the AUTOSAR OS on the virtual ECU. This is to reduce the simulation error caused by the dependence on the host computer environment and the generation of overhead in the case of highly computational in-vehicle embedded software, which have been pointed out as problems in ECU virtualization using QEMU. The experimental results of the proposed technique show that the simulation timing error rate of the virtual ECU compared to the physical ECU is reduced from an average of 2.40% to 0.02%. This shows that, just by reflecting the operational characteristics of the physical ECU in the QEMU-based virtual ECU, it is possible to improve the precision by reducing the timing error of the simulation. © 2023 IEEE. | Yang, Anna; Kim, Jin Yong; Seol, Woo Hyun; Han, Woo Jin; Kim, Hyng Rae; Cho, Jeonghun | Drimaes, Korea Aerospace Univ, Sdv Center, Seoul, South Korea; Drimaes, Sdv Center, Seoul, South Korea; Drimaes, Sdv Center, Seoul, South Korea; Drimaes, Sdv Center, Seoul, South Korea; Kyungpook National University, School of Electronics and Engineering, Daegu, South Korea; Kyungpook National University, School of Electronics and Engineering, Daegu, South Korea | 59065812900; 58875301200; 58876021600; 58876200300; 57203064517; 7403536198 | metamon@drimaes.com; | International Conference on ICT Convergence | 2162-1233 | 0.86 | 2025-06-25 | 2 | AUTOSAR; Operation Accuracy; QEMU; Simulation; virtual ECU | Automobile drivers; Embedded software; Embedded systems; Errors; Vehicle safety; Virtual reality; AutoSAR; Driver-assistance systems; Operation accuracy; QEMU; Simulation; Simulation error; Timing errors; Virtual ECU; Virtualization technologies; Virtualizations; Timing circuits | English | Final | 2023 | 10.1109/ictc58733.2023.10393554 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | Article | A multidisciplinary approach with immunotherapies for advanced hepatocellular carcinoma | Hepatocellular carcinoma (HCC) is a highly aggressive disease that is usually diagnosed at an advanced stage. Advanced HCC has limited treatment options and often has a poor prognosis. For the past decade, tyrosine kinase inhibitors have been the only treatments approved for advanced HCC that have shown overall survival (OS) benefits; however, but their clinical efficacy has been limited. Recent trials have demonstrated promising advancements in survival outcomes through immunotherapy-based treatments, such as combinations of immune checkpoint inhibitors (ICIs) with other ICIs, antiangiogenic drugs, and locoregional therapies. The atezolizumab-bevacizumab and durvalumab-tremelimumab (STRIDE) regimen has significantly improved survival rates as a first-line treatment and has become the new standard of care. Therefore, combined treatments for advanced HCC can result in better treatment outcomes owing to their synergistic effects, which requires a multidisciplinary approach. Ongoing studies are examining other therapeutic innovations that can improve disease control and OS rates. Despite improvements in the treatment of advanced HCC, further studies on the optimal treatment selection and sequences, biomarker identification, combination approaches with other therapies, and development of novel immunotherapy agents are required. This review presents the current treatment options and clinical data of the ICI-based combination immunotherapies for advanced HCC from a multidisciplinary perspective. © 2023 by The Korean Liver Cancer Association. | Lee, Yu Rim | Department of Internal Medicine, Kyungpook National University Chilgok Hospital, School of Medicine, Kyungpook National University, Daegu, South Korea | 57194094753 | deblue00@naver.com; | Journal of Liver Cancer | 2288-8128 | 23 | 2 | 2.01 | 2025-06-25 | 9 | Carcinoma, hepatocellular; Combined modality therapy; Immune checkpoint inhibitors; Locoregional therapy; Systemic treatment | English | Final | 2023 | 10.17998/jlc.2023.09.04 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | A Novel Data Management Scheme in Cloud for Micromachines | In cyber-physical systems (CPS), micromachines are typically deployed across a wide range of applications, including smart industry, smart healthcare, and smart cities. Providing on-premises resources for the storage and processing of huge data collected by such CPS applications is crucial. The cloud provides scalable storage and computation resources, typically through a cluster of virtual machines (VMs) with big data tools such as Hadoop MapReduce. In such a distributed environment, job latency and makespan are highly affected by excessive non-local executions due to various heterogeneities (hardware, VM, performance, and workload level). Existing approaches handle one or more of these heterogeneities; however, they do not account for the varying performance of storage disks. In this paper, we propose a prediction-based method for placing data blocks in virtual clusters to minimize the number of non-local executions. This is accomplished by applying a linear regression algorithm to determine the performance of disk storage on each physical machine hosting a virtual cluster. This allows us to place data blocks and execute map tasks where the data blocks are located. Furthermore, map tasks are scheduled based on VM performance to reduce job latency and makespan. We simulated our ideas and compared them with the existing schedulers in the Hadoop framework. The results show that the proposed method improves MapReduce performance in terms of job latency and makespan by minimizing non-local executions compared to other methods taken for evaluation. | Singh, Gurwinder; Jeyaraj, Rathinaraja; Sharma, Anil; Paul, Anand | Sikh Natl Coll, Dept Comp Sci & Applicat, Banga 144505, India; Univ Houston Victoria, Dept Comp & Informat Sci, Victoria, TX 77901 USA; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Lovely Profess Univ, Sch Comp Applicat, Phagwara 144001, Punjab, India | Paul, Anand/V-6724-2017; Jeyaraj, Rathinaraja/ABB-7781-2021 | 57212379981; 57203111601; 56712189400; 56650522400 | gurwinder.11@gmail.com;jrathinaraja@gmail.com;anil.19656@lpu.co.in;paul.editor@gmail.com; | ELECTRONICS | 2079-9292 | 12 | 18 | 0.12 | 2025-06-25 | 0 | 1 | cyber-physical system; data block placement; data locality; MapReduce scheduling | MAPREDUCE; PERFORMANCE; PLACEMENT; STRATEGY | cyber-physical system; data block placement; data locality; MapReduce scheduling | English | 2023 | 2023-09 | 10.3390/electronics12183807 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Proceedings Paper | A Nullspace-Based Predictive Control Allocation for the Control of a Quadcopter Manipulating an Object Attached to the Ground | In this paper, we propose a novel optimal predictive control allocation for the control of a quadcopter manipulating an object attached to the ground. This controller sprucely takes advantage of the nullspace of the quadcopter attitude mapped to the effective force to compute the optimal sequence of controls and attitude references. In particular, at each time instant, the controller solves a nonlinear minimization problem, where a specialized term is added to the cost function to penalize the deviation of the desired attitude from its nullspace, which is the attitude subspace for which any thrust generates zero effective force on the system. The weight associated to this specialized term uses a Gaussian bell-curve function to make the tuning of the attitude-reference generation more flexible and enhance the performance of the controller. To demonstrate the effectiveness of the proposed controller, numerical simulations of two different cases are provided.

| ○ | ○ | Proceedings Paper | A Physics-based Numerical Model of Resistive Switching Behavior in Electrochemical Metallization Memristor | Electrochemical metallization (ECM)-based memristors enable energy-efficient in-memory computing, which is desirable for edge computing. However, a physics-based numerical model for ECM memristor is not well established. In this work, we developed the physics-based model for ECM memristor, which includes the effect of both Joule heating and electric field effects on ion migration to elucidate the dynamics of formation and dissolution of conductive filaments. | Kim, Yeongkwon; Jang, Byung Chul | Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehakro, Daegu 41566, South Korea | Jang, Byung Chul/GYV-0656-2022 | 58120005900; 9238827900 | bc.jang@knu.ac.kr; | 2023 SILICON NANOELECTRONICS WORKSHOP, SNW | 2161-4636 | 0 | 2025-06-25 | 0 | 0 | Energy efficiency; Memristors; Numerical models; Edge computing; Electrochemicals; Energy efficient; Ion migration; Joules heating; Memristor; Metallisation; Physics-based; Physics-based models; Resistive switching behaviors; Metallizing | English | 2023 | 2023 | 10.23919/snw57900.2023.10183941 | 바로가기 | 바로가기 | 바로가기 |
