Efficient detection of oil spills is critical for minimizing environmental damage. This study introduces a novel approach utilizing deep learning, specifically the YOLOv8 architecture, augmented with advanced computer vision techniques for oil spill detection. Through meticulous dataset curation and model training, the YOLOv8 model achieved an impressive overall accuracy (R-score) of 0.531 and a Mean Average Precision (mAP) of 0.549. Performance varied across different spill types, with the model demonstrating notable accuracy in distinguishing between oil spills and natural features, achieving precision and recall rates of up to 0.75 and 0.68, respectively, for sheen detection. Visualizations such as box loss, class loss, and confusion matrices provide insights into the model’s performance dynamics, revealing a steady decrease in losses and an improvement in accuracy over epochs. In this dataset, the measurements are drone measurements performed by Port of Antwerp Bruges. Furthermore, practical applications showcase the model’s versatility in detecting various oil spill types in both image and video data, affirming its potential for real-world deployment in environmental monitoring and disaster response scenarios. This research represents a significant stride towards more effective oil spill detection, contributing to environmental sustainability and resilience efforts. © 2024 Copyright for this paper by its authors.

Diseases originated due to the disorder in the neurons present in the brain part of the body is called epilepsy and the symptom observed in other parts of the body is called a seizure. Not only it is a typical disease in human beings but animals are also suffered from this disease. To live an epilepsy-free life, neurologists and researchers contribute their best effort to devise new techniques and presently metaheuristic optimization algorithms and machine learning algorithms are integrated into this field to design powerful EEG devices for accurately detecting the presence of EEG signals. This research paper presents the comparison of three metaheuristic optimization algorithms used in designing EEG detection. In addition, these three algorithms are integrated with Extreme Learning Adoptive Neuro-Fuzzy-Inference System (ELANFIS) as the classifier and Wavelet Packet Transform as the feature extraction technique. For continuing research work, this experiment uses the Bonn University EEG dataset. After a thorough analysis, it is observed that WPT-PO-ELANFIS is the best-performing technique among these three with average accuracy, sensitivity, specificity, and area under curve values as 98.42, 96.75, 97.97.97.65, and 0.989. This research work also can be tested with other popularly available datasets and integrated with real-time applications. © 2025 IEEE.

This paper addresses the distributed fusion esti- mation problem of clustered sensor networks with multi-rate sampling and multi-scale fading. An eventtriggered distributed two-stage fusion estimation method is proposed for the clustered sensor network. Specifically, a local fusion estimator is firstly constructed to fuse multirate measurements transmitted through small-scale fading channels. The parameters of the estimator are computed by solving linear matrix inequalities (LMIs). Then, the event trigger mechanism (ETM) is utilized to adjust the transmission frequency of local estimates, aiming to conserve the energy of cluster heads. Furthermore, by solving a min-max optimization problem, a global fusion estimator is designed to fuse the local estimates in the presence of the ETM and large-scale fading channels. Sufficient conditions for the stochastic ultimate boundedness of both local and global estimation errors are derived by leveraging differential game theory and LMIs. The comparison simulation results on a DC-power network show the effectiveness and advantages of the proposed method. © 2014 IEEE.

Multiple Sclerosis (MS) disrupts nerve communication, potentially leading to permanent damage. Convolutional Neural Networks (CNNs) are commonly recommended to accelerate magnetic resonance imaging (MRI) analysis for MS. Traditional CNN-based methods often face challenges with feature selection, imbalanced classification, and hyperparameter optimization, which can reduce their effectiveness. To address these challenges, this paper introduces a reinforcement learning (RL) strategy for tackling feature selection and class imbalance, complemented by an advanced Differential Evolution (DE) algorithm for hyperparameter tuning. The RL algorithm dynamically adapts, enhancing feature selection and class balance, and consistently outperforms traditional static methods by continually optimizing its response to the complex patterns in MS detection. Furthermore, the DE is enhanced with a novel mutation mechanism that utilizes k-means clustering to identify significant clusters. Tested on the SNAC-MS and ISBI datasets, our model demonstrates robust accuracy with average F-measures of 92.873% and 93.783%, respectively, highlighting its effectiveness and adaptability in diagnosing MS.

The existence of noisy labels in real-world data negatively impacts the performance of deep learning models. Although much research effort has been devoted to improving the robustness towards noisy labels in classification tasks, the problem of noisy labels in deep metric learning (DML) remains under-explored. Existing noisy label learning methods designed for DML mainly discard suspicious noisy samples, resulting in a waste of the training data. To address this issue, we propose a noise-robust DML framework with SubGroup-based Positive-pair Selection (SGPS), which constructs reliable positive pairs for noisy samples to enhance the sample utilization. Specifically, SGPS first effectively identifies clean and noisy samples by a probability-based clean sample selectionstrategy. To further utilize the remaining noisy samples, we discover their potential similar samples based on the subgroup information given by a subgroup generation module and then aggregate them into informative positive prototypes for each noisy sample via a positive prototype generation module. Afterward, a new contrastive loss is tailored for the noisy samples with their selected positive pairs. SGPS can be easily integrated into the training process of existing pair-wise DML tasks, like image retrieval and face recognition. Extensive experiments on multiple synthetic and real-world large-scale label noise datasets demonstrate the effectiveness of our proposed method. Without any bells and whistles, our SGPS framework outperforms the state-of-the-art noisy label DML methods. Code is available at https://***/smuelpeng/SGPS-NoiseFreeDML. © 2025, CC BY.

Network coding is an applicable technique to enhance the performance of wireless relay networks, in which intermediate nodes are utilized to expand the coverage range and increase communication reliability. The utilization of network coding in these networks should be well addressed by resource allocation such as bandwidth and power allocation. Among them, network coding for resource allocation in wireless relay networks is the most attractive research work. In particular, dynamic network coding is a strategy that varies how we code data according to current conditions in the network so as to achieve the maximum possible throughput during relaying. Dual-joint power and resource combinations have relatively better performance gains due to the efficient channel gain with an additional level of resource utilization for enhanced resource allocation. In addition, network coding schemes, including opportunistic and homomorphic network coding, have been introduced to perform well in an environment with fading channels and enhance data transmitting reliability. These techniques take advantage of the intrinsic diversity in wireless pathways to improve overall network throughput and reduce latency.

The most important aspect aimed to develop a prediction model that could calculate a used car’s fair value based on a variety of factors, including the make, model year, fuel type, price, and miles. This study incorporated a lot of data science and machine learning approaches in the process of developing the model, which has a lot of promise and is available to manufacturers and other players in the used automobile market. The information used in this analysis came from a database of used car advertisements. To provide the best prediction accuracy, several regression techniques were evaluated, including decision tree regression, random forest regression, support vector regression, polynomial regression, and linear regression. To gain a deeper understanding of the data set, the research included substantial preprocessing and data visualization prior to the modeling step. To make it possible to evaluate the performance of each regression model, the data set was divided and modified to satisfy their specifications. The regression models were evaluated using the R-squared statistic. The final model presented in this study contains a wider range of used automobile attributes and provides better prediction accuracy when compared to previous investigations. This research promotes the used car industry and aids in the making of more informed judgments by providing a better model for pricing used cars. The benefits of sound data analysis and a range of regression techniques are used to increase the accuracy of such predictive models. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Innovative mobile artificial intelligence-generated content (AIGC) can support the evolution and updating processes of virtual twins (VTs) in human digital twin (HDT) systems. With a reliable and efficient automatic data generation process, the requirement for a timely physical-to-virtual synchronization in HDT can be satisfied. While such an AIGC-enabled HDT system can facilitate modelling high fidelity VTs, generating content that represents the true states in the physical environment and providing timely customized services, it may suffer from a poor understanding of contexts, a lack of creativity, and various security and privacy concerns. In this paper, we propose a novel framework, which integrates federated learning (FL) and semantic communication (SemCom) to enhance performance in the AIGC-enabled HDT system while improving accuracy and convergence properties. First, we present a holistic architectural framework for the proposed FL-enhanced SemCom (FLeS) solution for mobile AIGC-enabled HDT systems and discuss its design requirements and challenges. We later present key technologies necessary to realize the FLeS solution, followed by elaborating on important technical issues to suggest future directions. Experimental results demonstrate that FLeS not only facilitates reliable and personalized content generation but also shows better performance when compared to existing solutions. © 1986-2012 IEEE.

Background: Microprocessors and microcontrollers are ubiquitous in modern technology, driving applications across diverse fields. To prepare future engineers for Industry 4.0, effective educational approaches are crucial in this technology. Purpose: This paper proposes a novel curriculum for the microprocessors and microcontrollers laboratory course. The proposed curriculum blends structured laboratory experiments with an open-ended project phase while addressing complex engineering problems and activities. Design: Traditional microprocessors and microcontrollers curricula often fail to capture the complexity of real-world applications encountered in Industry 4.0. This curriculum addresses this gap by incorporating experts’ insights from both industry and academia. It trains students with the necessary skills and knowledge to thrive in this evolving technological landscape, preparing them for success upon graduation. After designing the course, we have taken feedback from the students which showed positive learning curve and experiences regarding this designed curriculum. Results: The proposed lab enables students to perform hands-on experiments using advanced microprocessors and microcontrollers where they can leverage their acquired knowledge by working in teams to tackle self-defined complex engineering problems that utilize these devices and sensors. Statistical analysis shows the proposed curriculum significantly improves student learning outcomes, particularly in their ability to both formulate and solve complex engineering problems as well as engaging in complex engineering activities. Conclusions: This curriculum integrates project-based learning, where students define complex engineering problems for themselves. Additionally, this proposed method fosters multidisciplinary learning and equips students with problem-solving skills that can be applied in real-world scenarios. This approach actively engages students, fostering deeper understanding and enhancing

Flexible-antenna systems, such as fluid antennas and movable antennas, have been recognized as key enabling technologies for sixth-generation (6G) wireless networks, as they can intelligently reconfigure the effective channel gains of the users and hence significantly improve their data transmission capabilities. However, existing flexible-antenna systems have been designed to combat small-scale fading in non-line-of-sight (NLoS) conditions. As a result, they lack the ability to establish line-of-sight links, which are typically 100 times stronger than NLoS links. In addition, existing flexible-antenna systems have limited flexibility, where adding/removing an antenna is not straightforward. This article introduces an innovative flexible-antenna system called pinching antennas, which are realized by applying small dielectric particles to waveguides. We first describe the basics of pinching-antenna systems and their ability to provide strong LoS links by deploying pinching antennas close to the users as well as their capability to scale up/down the antenna system. We then focus on communication scenarios with different numbers of waveguides and pinching antennas, where innovative approaches to implement multiple-input multiple-output and non-orthogonal multiple access are discussed. In addition, promising 6G-related applications of pinching antennas, including integrated sensing and communication and next-generation multiple access, are presented. Finally, important directions for future research, such as waveguide deployment and channel estimation, are highlighted. Copyright © 2025, The Authors. All rights reserved.
