To accurately model the mechanical properties of DLOs, a Kirchhoff differential model is employed, which parameterizes the DLO configuration as a 6-dimensional manifold. Traditionally, approaches to solving this planning problem relied solely on sampling-based methods, incurring high computational costs due to the necessity of obtaining the DLO shape for each sample. Additionally, these methods completely ignored gravity, assuming that the DLO was stiff enough. However, in many industrial scenarios, this assumption cannot hold, particularly when dealing with soft DLOs, where the effects of gravity are non-negligible, leading to poorer stability and sensitivity. In this work, a novel optimization-based paradigm is proposed for the manipulation planning of soft DLOs with dual arms, addressing the challenges associated with their soft nature and the influence of gravity. The concept of ’stability distance’ is introduced as an easily measurable indicator of the degree of DLO stability. Furthermore, a thorough investigation into the singularity phenomenon in DLO local leading is conducted to identify its causes and provide effective solutions. Additionally, a strategy is introduced to avoid local traps of the DLO in complex obstacle environments. The comprehensive planner is validated through both simulation and hardware experiments, utilizing two types of soft DLOs with a length of approximately 1 m in various environmental settings. The results demonstrate the promising performance of the algorithm across diverse assembly scenarios.</div></div>","PeriodicalId":50941,"journal":{"name":"Advanced Engineering Informatics","volume":"62 ","pages":"Article 102874"},"PeriodicalIF":8.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142446797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To solve the above problems, a multi-sensor fused incremental detection model (MFIDM) for blade cracks with the cross-attention mechanism and the Dempster-Shafer evidence theory (DST) is proposed. Firstly, vibration signals of centrifugal fans are collected by multiple accelerometers deployed at different locations.

After that, the fused features are fed into a Softmax classifier to complete the initial classification of blade status. Finally, a modified DST based on the cross-correlation energy is adopted for multi-sensor decision fusion to obtain the final blade crack detection results.

Knowledge graph, as a method of knowledge representation, holds significant promise for addressing challenges within industrial contexts. However, current research on knowledge graph has a limitation in that task related knowledge graph focus on structure information, while ignoring semantic and logical information in knowledge. Additionally, the existing ontologies designed for industrial production lack adaptability to cater to the diverse needs of different industrial tasks. This paper proposes a multi-level knowledge graph defined by ontology to introduce semantics and further explore the methods for combining semantics to complete practical industrial tasks. To ensure the accurate sampling of heterogeneous nodes, four semantic templates are generated using if-then rule logic. Different kinds of neighbor nodes are defined through the if-then rule logic, leading to a accelerated generation of target subgraphs related to different tasks. In this way, the plant-wide distributed computing for fault diagnosis tasks can be easily realized. Furthermore, this paper introduces a framework for semantics extraction and graph embedding based on multi-information fusion. This framework integrates semantic information, structural information, and node attribute information within the graph to deliver a holistic feature representation for prediction and control tasks. We take blast furnace ironmaking process as an industrial case study and the experimental results demonstrate the crucial role of semantics in enhancing the knowledge expression capability of graphs. Based on the blast furnace simulation experiment platform, the proposed method achieves 92.76% accuracy in the blast furnace fault diagnosis task, and the diagnosis time is reduced by 58.44% compared with the traditional rule-based method. In the self-healing control task of the blast furnace, the proposed graph embedding method can achieve a complete control process in three types of blast furnace faults: blowing out, tuyere failure, and low stockline. The control effect can be comparable to manual operation.</div></div>","PeriodicalId":50941,"journal":{"name":"Advanced Engineering Informatics","volume":"62 ","pages":"Article 102927"},"PeriodicalIF":8.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142659113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, EEG data is highly susceptible to interference from various artifacts, which, in turn, can severely impact the subsequent analyses. As a result, the removal of these unwanted artifacts is of utmost importance. Recently, deep learning methods have demonstrated superior performance in artifact removal compared to traditional approaches. However, experts often invest substantial time and effort in identifying an efficient architecture, a process that is time-consuming and labor-intensive. In light of this challenge, this study introduces, for the first time, an artifact removal method based on neural network architecture search. This approach assigns probabilities to each potential operation within the network and optimizes the most suitable architecture based on the characteristics of the input data. Additionally, we expand the search space by incorporating large convolutional kernels, enabling the network to encompass a wider receptive field for the more effective capture of inherent EEG characteristics. The proposed method is evaluated on publicly available datasets, including electromyography (EMG), electrooculogram (EOG), electrocardiogram (ECG), and motion artifacts. Our results demonstrate that architectures incorporating convolution operations with varied kernel scales and shortcut connections are particularly effective for artifact removal. Notably, our method outperforms state-of-the-art techniques, achieving an average correlation coefficient (CC) exceeding 0.95, a relative root mean squared error (RRMSE) below 0.3, and a signal-to-noise ratio (SNR) above 12 dB.

However, traditional approaches to product shape design often rely heavily on the designer’s intuition and experience, sometimes neglecting to incorporate emotional and humanistic elements into the product’s shape, thus resulting in inconsistencies in design results and quality. To address this challenge, this study introduces a novel method for emotionally driven product shape design that integrates Kansei engineering and the Whale Optimization Algorithm (WOA). This approach aims to fulfill consumer emotional demands related to product form and enhance overall user satisfaction. Firstly, the process utilized Python web crawlers to collect online product review texts and product images from e-commerce platforms. Next, Latent Dirichlet Allocation (LDA) and Analytic Hierarchy Process (AHP) were employed to extract representative emotional vocabularies, while representative samples were defined and deconstructed through clustering and morphological analysis. Then, semantic Differential (SD) questionnaires were distributed to collect consumer evaluations of product shape imagery, leading to the development of a user emotional prediction model for product shape. Then, WOA was introduced to optimize the performance of Back Propagation Neural Network (BPNN) and Support Vector Regression (SVR) models. Finally, Particle Swarm Optimization (PSO) and Seagull Optimization Algorithm (SOA) were employed to improve the prediction model, and the effect of these models was compared by the error method. This analysis explored the accuracy of these non-linear models in order to identify the optimal model for application in product form design cases. The scientific validity and effectiveness of this method were demonstrated utilizing whiskey bottle shape design as a case study. The results exhibit that under the WOA-BPNN model, the average error rates for four sets of perceptual words were 3.08%, 2.60%, 6.53%, and 5.70%, respectively.
