Effective view planning for image collection significantly impacts the quality of photogrammetry-based 3D reconstruction. Intricate building structures, such as the overhangs, protrusions, and concave regions, can lead to under-sampled regions with traditional view planning methods, while excessively increasing the number of views require substantial computational resources and data collection efforts. To address these issues, this paper proposes a novel exploration-then-exploitation view planning strategy to achieve high-quality building reconstruction with minimal views. Firstly, the UAV no-fly regions and building attention regions are identified through semantic and geometric analysis of the images and coarse model during the exploration stage. Then, a novel optimization fitness function is mathematically formulated, considering building attention regions and reconstruction influential factors, including distance, incidence angle, parallax angle, and overlap. Furthermore, a modified sparrow search algorithm is proposed with the improved optimization mechanism and the integration of view planning physical model, enabling effective generation of optimal viewpoint set. Finally, the collision-free shortest trajectory is designed, allowing the UAV to collect images and reconstruct a high-quality model during exploitation stage. Experiments in virtual and real-world scenarios validate the effectiveness of our proposed modified SSA mechanism and the view planning strategy. Results demonstrate that the modified SSA achieves higher convergence accuracy and speed compared to the original SSA, PSO and GA. Our strategy can generate more accurate and complete 3D reconstruction models with the same or fewer captured images compared to commonly used and state-of-the-art strategies.</div></div>","PeriodicalId":50941,"journal":{"name":"Advanced Engineering Informatics","volume":"65 ","pages":"Article 103344"},"PeriodicalIF":8.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143842568","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}

Industry 4.0 (I4.0) adoption in this sector leads to the development of data-driven solutions, manufacturing innovations, higher demand for newer services, and improved operational efficiency. For the successful adoption of I4.0, their strategies should be evaluated with respect to certain criteria. To this aim, this study introduces an integrated Pythagorean fuzzy Comprehensive Distance-Based Ranking (COBRA) approach to evaluate and prioritize the adoption strategies in the automotive manufacturing sector. The proposed framework is divided into four phases. In the first phase, the decision experts’ (DEs) weights are computed with the use of the score function and rank sum model (RSM). In the next phase, an aggregated Pythagorean fuzzy decision matrix is created through a fairly power-weighted operator. For this purpose, the Pythagorean fuzzy fairly power-weighted aggregation operators are introduced to combine individual Pythagorean Fuzzy Information (PFI). In the third phase, the criteria weights are obtained through a combined weighting procedure involving the objective weight by standard deviation (SD)-based method and the subjective weight via Stepwise Weight Assessment Ratio Analysis (SWARA) tool. Based on these phases, a novel Pythagorean fuzzy COBRA approach is developed to deal with the I4.0 adoption strategies evaluation problem. A novel distance measure is also offered to describe the degree of dissimilarity between Pythagorean fuzzy sets (PFSs). Moreover, a comparison with existing distances is discussed to demonstrate the efficiency of the developed distance measure. The suggested methodology is then applied to a case study of the I4.0 adoption strategy selection problem within the context of PFI.

Current EEG-based BMIs face limitations in adaptability, usability, and robustness, especially in applications like virtual keyboards, as traditional machine-learning models struggle to handle high-dimensional EEG data effectively. To address these gaps, we developed an EEG-based BMI system capable of accurately identifying voluntary keystrokes, specifically leveraging right and left voluntary hand movements. Using a publicly available EEG dataset, the signals were pre-processed with band-pass filtering, segmented into 22-electrode arrays, and refined into event-related potential (ERP) windows, resulting in a 19x200 feature array categorized into three classes: resting state (0), ’d’ key press (1), and ’l’ key press (2). Our approach employs a hybrid neural network architecture with BiGRU-Attention as the proposed model for interpreting EEG signals, achieving superior test accuracy of 90% and a mean accuracy of 91% in 10-fold stratified cross-validation. This performance outperforms traditional ML methods like Support Vector Machines (SVMs) and Naive Bayes, as well as advanced architectures such as Transformers, CNN-Transformer hybrids, and EEGNet. Finally, the BiGRU-Attention model is integrated into a real-time graphical user interface (GUI) to simulate and predict keystrokes from brain activity. Our work demonstrates how deep learning can advance EEG-based BMI systems by addressing the challenges of signal interpretation and classification.

However, considering the inherent uncertainties that exist within the structural responses to ever-fluctuating environmental factors like water levels and temperatures, which directly affect dam displacement behaviour, it is clear that mere point predictions are insufficient to accurately quantify the resultant uncertainty. To address this issue, we propose a multivariate probabilistic prediction framework that integrates the extended matrix long short-term memory-embedded attention sequence-to-sequence (Att-S2S-mLSTM) model with the density-based adaptive kernel density estimation (DAKDE). Specifically, the designed mLSTM incorporates a matrix memory and a covariance update rule to effectively simulate the complex nonlinear relationship between environmental factors and dam displacements. The Att-S2S architecture dynamically models sequential monitoring data of varying lengths, where the attention mechanism further augments its capacity to capture long-range dependencies, consequently generating displacement predictions with minimized errors. The DAKDE method then exploits the local density of prediction residuals obtained from Att-S2S-mLSTM to adaptively construct probability density functions. In this case, reliable prediction intervals are derived at various confidence levels, which are regarded as probabilistic predictions and serve as uncertainty quantification associated with displacement predictions. The large amount of monitoring data collected from a real-world concrete dam is employed to verify the effectiveness and superiority of the proposed framework. Moreover, a set of comparisons made among our proposed model and other advanced methods demonstrate that our methodology is more accurate and robust than other baselines in making both point and probabilistic predictions for dam displacement behaviour.</div></div>","PeriodicalId":50941,"journal":{"name":"Advanced Engineering Informatics","volume":"65 ","pages":"Article 103343"},"PeriodicalIF":8.0,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143843267","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}

A 4D grid-based conflict risk assessment method is introduced for trajectories generated by the ensemble trajectory predictor, incorporating weather uncertainty from ensemble forecasts. A multi-objective optimization model is formulated to reorganize aircraft trajectories within free route airspace, employing rerouting, flight level allocation, and speed control to optimize safety, efficiency, and predictability. Predictability is explicitly considered to enhance adherence to planned trajectories and reduce operational uncertainty, while equity is incorporated as a constraint to ensure a fair distribution of trajectory adjustments. To efficiently solve this large-scale multi-objective SCM problem, a decomposition-based memetic algorithm (DMA) is proposed. The DMA combines a decomposition-based global search framework with local refinement via a hybridization strategy to achieve a good balance between exploration and exploitation. The effectiveness of the proposed method is validated using a simulation scenario featuring 760 flights in the high-density western China airspace.

With advancements in coverage range and payload capacity, medium drones are poised to open up a medium-range urban logistics market known as intra-city express service (ICES). This study aims to examine the benefits of deploying drones into ICES by comparing the costs and efficiency of current truck-based ICES with four potential drone-based modes: station-to-station (S-S), vertiport-to-vertiport (V-V), station-to-hub-to-station (S-H-S, with hub denoting distribution center), and vertiport-to-hub-to-vertiport (V-H-V). Based on the dataset from a courier in China, a thorough examination of the cost- and time-saving advantages associated with drone-based modes is conducted. The results demonstrate the promising potential of deploying drones in the ICES industry to save costs and enhance efficiency, but these benefits are highly dependent on the operational mode of drones. Among the proposed modes, none emerges as a dominant option across both metrics. Nevertheless, the V-V and V-H-V stand out as non-dominant modes, with V-V offering the highest time efficiency and V-H-V proving to be the most cost-efficient. Vertiports and distribution centers are crucial facilities for achieving cost reduction as they facilitate parcel consolidation.
