software clone detection is an actively researched area which has spawned numerous approaches to the problem of duplicated code. These approaches, however, are of little practical use as most of them are ill-suited for incremental analysis required by the developers in their day-to-day activities. This paper tackles the problem of clone detection from the practical point of view, in the context of IDE integration, and presents an online clone detection algorithm based on extended suffix trees. The approach has been tested in a prototype plugin for IntelliJ IDEA and proved its applicability in the industrial setting. © 2015 ACM.

In this paper, we propose a distributionally robust control synthesis for an agent with stochastic dynamics that interacts with other agents under uncertainties and constraints expressed by signal temporal logic (STL). We formulate the control synthesis as a chance-constrained program (CCP) with STL specifications that must be satisfied with high probability under all uncertainty tubes induced by the other agents. To tackle the CCP, we propose two methods based on concentration of measure (CoM) theory and conditional value at risk (CVaR) and compare the required assumptions and resulting optimizations. These approaches convert the CCP into an expectation-constrained program (ECP), which is simpler to solve than the original CCP. To estimate the expectation using a finite set of observed data, we adopt a distributionally robust optimization (DRO) approach. The underlying DRO can be approximated as a robust data-driven optimization that provides a probabilistic under-approximation to the original ECP, where the probability depends on the number of samples. Therefore, under feasibility, the original STL constraints are satisfied with two layers of designed confidence: the confidence of the chance constraint and the confidence of the approximated data-driven optimization, which depends on the number of samples. We then provide details on solving the resulting robust data-driven optimization numerically. Finally, we compare the two proposed approaches through case studies. Copyright © 2025, The Authors.

Energy resilience in renewable energy sources dissemination components such as batteries and inverters is crucial for achieving high operational fidelity. Resilience factors play a vital role in determining the performance of power systems, regardless of their operating environment and interruptions. This article introduces a Unified Resilience Model (URM) using Deep Learning (DL) to enhance power system performance. The proposed model analyzes environmental factors impacting the resilience of batteries and energy storage devices. This deep learning approach trains performance-impacting factors using previously known low resilience drain data. The learning output is utilized to augment various strengthening factors, thereby improving resilience. Drain mitigation and performance improvements are combined for direct impact verification. This process validates the model's fidelity in enhancing power system performance, with a specific focus on the impact of weather factors. © 2025 The Authors

Robust sliding mode control of general time-varying delay stochastic systems with structural uncertainties

Control Theory and Technology 2014年第4期12卷 357-367页

College of Mathematics and Computer Science Fuzhou University

This paper presents a new robust sliding mode control （SMC） method with well-developed theoretical proof for general uncertain time-varying delay stochastic systems with structural uncertainties and the Brownian noise （Wiener process）. The key features of the proposed method are to apply singular value decomposition （SVD） to all structural uncertainties and to introduce adjustable parameters for control design along with the SMC method. It leads to a less-conservative condition for robust stability and a new robust controller for the general uncertain stochastic systems via linear matrix inequality （LMI） forms. The system states are able to reach the SMC switching surface as guaranteed in probability 1. Furthermore, it is theoretically proved that the proposed method with the SVD and adjustable parameters is less conservatism than the method without the SVD. The paper is mainly to provide all strict theoretical proofs for the method and results.

Domain adaptive person re-identification via homogeneous hierarchical progressive adaptation and multi-view consistency

引用

Advanced engineering Informatics 2025年 67卷

作者： Zhengyang Wang Xiufen Ye Xue Shang Shuxiang Guo College of Intelligent Systems Science and Engineering Harbin Engineering University Harbin 150001 China Department of Electrical Computer and Software Engineering University of Auckland Auckland 1142 New Zealand Department of Electronic and Electrical Engineering Southern University of Science and Technology Shenzhen 518055 China

Domain adaptive person re-identification (Re-ID) encounters significant challenges when models trained on one dataset are deployed in new environments. It is particularly critical in engineering applications where surveillance infrastructure must be rapidly adapted to new environments without compromising security system reliability. The problem represents a knowledge-intensive engineering task that requires sophisticated knowledge representation and transfer mechanisms to support automated system reconfiguration decisions. These challenges include preserving fine-grained visual details, handling camera-specific variations, generating reliable pseudo-labels, maintaining consistency across multiple camera views, and managing varying difficulty levels in domain transfer. To address these issues, we propose a novel framework that separates adaptation into intra-domain and cross-domain learning phases. Our approach introduces several key innovations: an adaptive fine-grained network that preserves spatial details while ensuring domain invariance, a memory-guided learning method for stable feature representation, and a hierarchical adaptation strategy for reliable intra-domain learning. Additionally, we incorporate a progressive learning strategy for gradual domain adaptation and a consistency reinforcement mechanism to resolve cross-camera identity conflicts. Experiments on the Market-1501, DukeMTMC-reID, and MSMT17 datasets across four domain adaptation tasks show that our method outperforms state-of-the-art approaches, significantly improving both mAP and CMC accuracy. This work contributes to engineering informatics by providing a reliable solution for automating knowledge-intensive tasks across diverse engineering domains, while also laying the foundation for advancements in intelligent surveillance systems and automated decision-making in engineering infrastructures.

High-speed software development practices: What works, what doesn't

引用

IT Professional 2006年第4期8卷 29-36页

作者： Baskerville, Richard Ramesh, Balasubramaniam Levine, Linda Pries-Heje, Jan Department of Computer Information Systems Georgia State University Carnegie Mellon University Software Engineering Institute Department of Design of Organizational IT IT University of Copenhagen

An empirical study of high-speed software development practices was conducted in US companies. Fast development, along with low cost and high quality has formed a tripartite tension among software engineering goals. The detailed case studies of Internet software development were reviewed in 10 companies and then knowledge was synthesized on best practice for quality and agility. Agile methodologies, including Extreme Programming and Scrum are found increasing in the software development field. Some of the problems identified in high speed software development, include demands of time-to-market compression, insufficient programmer productivity, ambiguous requirements, fluid requirements, lack of design time and experience, and changing environment. The solutions to the problems identified, include parallel development and frequent releases, greater reliance on tools and reusable components, production prototyping, customer implantation, multitiered architecture and emphasis on acquiring the right expertise and tailored methodology.

Workshop on Models and Their Role in Collaboration, MoRoCo 2013 - Co-located with the 13th European Conference on computer Supported Cooperative Work, ECSCW 2013

作者： Bartelt, Christian Vogel, Martin Warnecke, Tim Software Systems Engineering Department for Computer Science University of Clausthal Germany

Most of the time developers make extensive use of software tools in a software development process to support them in their day-to-day work. One of the first and most important phases is the design phase. Here tools are missing which support the creative and collaborative workflow (parallel/distributed). At the moment software designers uses classic whiteboards in team meetings to express their ideas. Subsequently a coworker uses a mobile phone or a camera to take photos of the work and remodel the picture with a modeling tool. That process is very inconvenient, error-prone and hinders a creative modeling cycle. For overcoming this ineffective process this paper shows a new approach to use digital whiteboards to transform free hand sketches in formal models and back again while modeling in a distributed team. The approach is completely independent from a pre-defined modeling language. It provides an interactive training mode to learn new graphical syntax elements and map these elements to formal metamodel entities. Based on the approach a collaborative sketch and modeling infrastructure was implemented. Copyright © 2013 for the individual papers by the papers' authors.
