AGC tuning is split into two stages: unit control logic parameters and AGC system. In order to determine the optimal parameters, the application of a heuristic optimization algorithm, named MVMO (Mean-Variance Mapping Optimization), is proposed to solve a defined optimization problem. The proposed tuning methodology is validated using a realistic simulation environment named Operator Training Simulator (OTS). In addition, AGC system parameters are determined from real SCADA records and primary frequency response (PFR) obtained from frequency events recorded by the Ecuadorian WAMS (Wide Area Monitoring System). Finally, the AGC system is modeled in PowerFactory with the aim of achieving a realistic AGC model, considering a multimachine power system. For this aim, AGC control is implemented considering the realistic four-seconds sampling period related to a SCADA/EMS and the implementation of a filter that measures the rate of change of frequency (ROCOF) for allowing the primary frequency control to be previously performed. This model is then validated by simulations of generation outage events using a reduced model of the Ecuador-Colombia interconnected power system in PowerFactory.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10412029","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139572683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite its vast quantity and diversity of data, a considerable portion of the existing records suffer from disjointed and often lacking metadata, failing to provide the necessary context of their acquisition. In light of this, we propose GeneConnector, a tool that harnesses shared information among multiple records of the same specimen in Genbank, aiming to enhance the completeness of poorly annotated nodes across various information domains. To demonstrate the tools capabilities, we conducted a comprehensive review and aggregation of available data using the Genbank database of Genera of Phytopathogenic Fungi (GOPHY). Through our evaluation, we observed substantial gains in information by analyzing shared data among nodes connecting Genbank specimen records, resulting in impressive increments ranging from 2% to a remarkable 60%. Our approach empowers users to make precise, straightforward, and accurate assessments of the context associated to results, facilitated by two metrics that gauge the current level of data annotation and the potential information gain achievable following our evaluation.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10412034","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139572680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Self-adaptive Cyber-Physical Systems (Self-CPS) present specific features compared to traditional CPS because this type of system can deal with changes at runtime. In parallel, Reference Architectures (RA) enable reusable artifacts that aggregate the knowledge of software architectures in specific domains. RAs have facilitated the development, standardization, and system evolution in different domains. Despite their relevance, reference architectures that could support the more systematic development of Self-CPS, covering issues like self-protecting and observability, are not found yet. Based on this scenario, the main contribution of this paper is to present an RA for Self-CPS named RA4Self-CPS. The goal of this RA is to support the Self-CPS development that requires self-protecting, observability, and adaptation at runtime. To show the viability of our RA, we conducted a case study that revealed a good perspective to contribute to the Self-CPS area.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10412036","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139572682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The focus is not merely on the correlation between simplified and complex models but on the added value such models can bring to the automotive industry. By comparing the simplified models based on bicycle representation with a high-fidelity VI-CarRealTime (VI-CRT) model, this paper demonstrates that the simplified models have good correlation and offer computational advantages. This approach addresses the key dynamics essential for ESC and considers a generic sedan vehicle model to simulate standard maneuvers widely performed by the automotive industry. All the proposed models are nonlinear and include tire modeling based on the Magic Formula, with parameters derived from experimental tests. The paper also introduces a methodology for parameter optimization, enhancing the model's accuracy and reliability. The results indicate that the simplified models can be a viable alternative for specific applications such as control strategy tuning, rapid prototyping, and early-stage development. This work aims to fill the gap in the literature concerning the practical applicability and limitations of simplified vehicle dynamics models, thereby making a significant contribution to the field.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10412038","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139573229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing fusion algorithms effectively utilize the complementary data from both sensors. However, these methods typically concatenate the raw point cloud data and pixel-level image features, unfortunately, a process that introduces errors and results in the loss of critical information embedded in each modality. To mitigate the problem of lost feature information, this paper proposes a Cross-Attention Dynamic Fusion (CADF) strategy that dynamically fuses the two heterogeneous data sources. In addition, we acknowledge the issue of insufficient data augmentation for these two diverse modalities. To combat this, we propose a Synchronous Data Augmentation (SDA) strategy designed to enhance training efficiency. We have tested our method using the KITTI and nuScenes datasets, and the results have been promising. Remarkably, our top-performing model attained an 82.52% mAP on the KITTI test benchmark, outperforming other state-of-the-art methods.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10412035","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139572681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
