Researchers at Texas A&M Universitv have studied the effects of battle damage on ship power distribution cables, with particular interest in damaged cables which did not fail immediately. The electrical signatures of partiallv damaged cables are significant and are detectable with advanced protection methods used on terrestrial power svstems. Findings show that the damaged cable signatures are similar to those of arcing faults on terrestrial power distribution svstems, which can be reliably detected using an on-line expert svstem [1,2,3]. The implications of these findings are significant. Since the abilitv of a damaged ship to right through an encounter is entirelv dependent on keeping operational its various systems which rely on electric power, the ability to automatically detect and re-route power around damaged regions is imperative. By identifving the characteristics of failing power cables before catastrophic failure occurs, the protection process can be integrated into the ship automatic control system. The overall result is a more survivable ship.

The development of theoretical techniques for the instantaneous calculation of load current components is evaluated. The associated instantaneous calculation of load power components is also evaluated since it is used in the calculation of the currents. The generation of these different power components with respect to compensation are pointed out. Further implementation of the instantaneous power theory is discussed. A three‐phase vector approach to the instantaneous calculation of power components is also discussed. Experimental results obtained by using the instantaneous power theory are illustrated.

Application of a Bilinear Long-Range Predictive control Method in a Distillation process

引用

IFAC Proceedings Volumes 1992年第5期25卷 249-254页

作者： Kun Lo En Sup Yoon Yeong-Koo Yeo Hyung-Keun Song Department of Chemical Engineering Seoul National University Seoul 151-742 Korea Process Control Laboratory Korea Institute of Science and Technology Seoul 136-791 Korea

Long-range predictive controllers for discrete-time MIMO bilinear processes are derived based on a new bilinear model with integral action. Using this model a multi-step-ahead optimal predictor is derived. Two alternative solution methods - rigorous and shortcut - of the minimization problem of a long-range objective function are established and used to calculate control inputs. Several simulation results show that the proposed control methods have robustness to the limited a priori knowledge of the process. Dynamic simulation on dual composition control of a binary distillation process showed satisfactory servo and regulatory performances of the proposed algorithms.

TFGIN: Tight-Fitting Graph Inference Network for Table-based Fact Verification

引用

ACM Transactions on Information Systems 1000年

作者： Lianwei Wu Kang Wang Kunlin Nie Sensen Guo Chao Gao Zhen Wang Shudong Li School of Computer Science Northwestern Polytechinical University China The 15th Research Institute of China Electronics Technology Group Corporation China Xidian University China Northwestern Polytechinical University China the Cyberspace Institute of Advanced Technology Guangdong Key Laboratory of Industrial Control System Security and Huangpu Research School Guangzhou University China

Fact verification task has emerged as an essential research topic recently due to abundant fake news spreading on the Internet. The task based on unstructured data (i.e., news) has achieved great development, but the task based on structured data (i.e., table) is still in the primary development period. The existing methods usually construct complete heterogeneous graph networks around statement, table, and program subgraphs, and then infer to learn similar semantics on them for fact verification. However, they generally connect the nodes with the same content between subgraphs directly to frame a larger graph network, which has serious sparsity in connections, especially when subgraphs possess limited semantics. To this end, we propose tight-fitting graph inference network (TFGIN), which innovatively builds tight-fitting graphs (TF-graph) to strengthen the connections of subgraphs, and designs inference modeling layer (IML) to learn coherence evidence for fact verification. Specifically, different from traditional connection ways, the constructed TF-graph enhances inter-graph and intra-graph connections of subgraphs through subgraph segmentation and interaction guidance mechanisms. Inference modeling layer could reason the semantics with strong correlation and high consistency as explainable evidence. Experiments on three competitive datasets confirm the superiority and scalability of our TFGIN.

AEKG4APT: An AI-Enhanced Knowledge Graph for advanced Persistent Threats with Large Language Model Analysis

引用

ACM Transactions on Intelligent Systems and technology 1000年

作者： Yinghai Zhou Ziyu Wang Yunxin Jiang Bingqi Ma Rui Wang Yuan Liu Yue Zhao Zhihong Tian Cyberspace Institute of Advanced Technology Guangzhou University China National Key Laboratory of Security Communication China Cyberspace Institute of Advanced Technology Guangzhou University with the Guangdong Key Laboratory of Industrial Control System Security and also with Huangpu Research School of Guangzhou University China

This paper introduces AEKG4APT, an APT Knowledge Graph (KG) enhanced by Large Language Models (LLMs), as a way to deal with the cybersecurity problems caused by advanced Persistent Threats (APTs). The core of AEKG4APT lies in the combined application of LLMs, Cyber Threat Intelligence (CTI), and KG. The first part of the paper goes into great detail about how the AEKG4APT was constructed, including its ontology schema, data sources, and dataset features. There are also statistics on the AEKG4APT’s nodes, relationships, and key attributes. Secondly, it was shown how to utilize LLMs and public sandboxes for the collection and analysis of CTI Additionally, tests that compare traditional deep learning models to LLM methods show that LLM is both more efficient and more accurate at extracting information. Subsequently, the Decision Making Trial and Evaluation laboratory - Interpretive Structural Modeling (DEMATEL-ISM) analytical method was introduced to identify and analyse the factors and their interrelationships within the AEKG4APT data, thereby revealing the key dependencies and influence paths within the data structure. Experiments were designed to demonstrate its applications in modeling, computing, and obtaining interpretable computational results on AEKG4APT. In addition, this paper also explores the dynamic expansion capabilities of AEKG4APT, including data expansion, schema expansion, and permanent maintenance strategies, to address the evolving APT threats. Finally, this paper summarizes the competitiveness and application value of AEKG4APT by comparing it with other CTI KGs and platforms in academia and industry, demonstrating its extensive application potential in the field of cybersecurity.
