The proposed circuit serves various purposes, including smart controllers, fractional-order controllers, optimal controllers, anti-aliasing filter, and programmable filters. The input signal of the transfer function is continuous and remains continuous throughout the circuit until the output signal is obtained. The proposed approach decomposes the transfer function into elementary first and/or second-order low-pass filters. A new analog first-order low-pass filter circuit is presented, offering advantages over conventional active first-order low-pass filters circuits. These benefits include DC gain and time constant independent of resistor ohmic values, enabling the use of smaller resistors and capacitors for low frequencies, and an expanded frequency working range. Similarly, a new analog circuit for a second-order low-pass filter is proposed, specifically used to obtain complex conjugate poles. The use of digital potentiometers and digital switches controlled by a micro-controller, makes this analog circuit configurable in real-time. As an application, the new circuit is used to realize fractional integrator controller. The circuit gives good similarity between theoretical and experimental measurements. © 2024 Elsevier GmbH |

Fuzzy Divergence Weighted Ensemble Clustering With Spectral Learning Based On Random Projections For Big Data Article de journal Dans: IEEE Access, p. 1-1, 2024, ISSN: 2169-3536. Résumé | Liens | BibTeX | Étiquettes: Matrix converters;Entropy;Clustering algorithms;Uncertainty;Reliability;Weight measurement;Sparse matrices;Ensemble learning;Fuzzy systems;Spectral analysis;Fuzzy ensemble clustering;High-dimensional data;Random projection;Kullback-Leibler divergence entropy;Spectral learning @article{10415440, In many real-world applications, data are described by high-dimensional feature spaces, posing new challenges for current ensemble clustering methods. The goal is to combine sets of base clusters to enhance clustering accuracy, but this makes them susceptible to low quality. However, the reliability of present ensemble clustering in high-dimensional data still needs improvement. In this context, we propose a new fuzzy divergence-weighted ensemble clustering based on random projection and spectral learning. Firstly, random projection (RP) is used to create various dimensional data and find membership matrices via fuzzy c-means (FCM). Secondly, fuzzy partitions of random projections are ranked using entropy-based local weighting along with Kullback-Leibler (KL) divergence to detect any uncertainty. Then it used to evaluate the weight of each cluster. Finally, we create regularized graphs from these membership matrices and use spectral matrices to estimate the affinity matrices of these graphs using fuzzy KL divergence anchor graphs. Subsequently, obtaining the final clustering results is considered as an optimization problem, and the ensemble clustering results are obtained. The experimental results on high-dimensional data demonstrate the efficiency of our method compared to state-of-the-art methods. |

However, such systems have different configurations and strategies, each with its own advantages and drawbacks. To design a suitable system, this paper proposes a method that utilizes a single-stage conversion system with hydraulic storage. In this method, the predictive torque controller (PTC) adjusts the inverter switching while the electrical storage in batteries is replaced by the potential energy of water in tanks. The PTC works side-by-side with a maximum power point tracking (MPPT) technique to supply the optimal power to the water-pumping Induction Motor (IM). This maximum power tracking is maintained during the day hours to provide and store water, whereas the water supply is guaranteed due to the gravity at night. The effectiveness of the proposed system is evaluated through MATLAB/Simulink-based results, demonstrating that the single-stage configuration outperforms the double-stage configuration in terms of power optimization, torque ripples, and power loss reduction. Furthermore, the suggested system offers the advantage of cost-effective installation due to its simple structure. © 2023 Taylor & Francis Group, LLC. |

The novelty of this design departs from the common use of integrators in ΣΔ modulators by emphasizing the design of delay components. This unique architecture maintains the oversampling frequency across different bands. The reconfigurability of the ADC is achieved by altering the modulator’s order. Specifically, in the Bluetooth and Zigbee bands, only the top two stages (2nd order mash 11) are active, while in the Wi-Fi band, all three stages (3rd order mash 111) are engaged. The reconfigurable ADC is implemented on a Xilinx board for practical application. © 2023 IEEE. |

This is achieved by adding an arrangement of three split-ring resonator (SRR) cells (placed in the Y-plane) between 2-element MIMO antennas that are positioned in the X-plane. The SRR design is intended to provide bandstop functionality within the antenna bandwidth. As a result, the mutual coupling level is reduced by 23 dB while maintaining the antenna’s performance and by packing the MIMO structure with three cells of SRR. In addition, the prototype antenna’s simulated isolation varies from -32 to -55 dB on the frequency band of 25.5-26.6 GHz. The reflection coefficient is roughly -40 dB at 26 GHz, with a high gain of 7.5 dB and efficiency higher than 90%. This makes our antenna an effective competitor for MIMO applications at the 26 GHz band enabling the fifth generation (5G) cellular communications. © 2023 IEEE. |

By taking the fault as an auxiliary state vector, the proposed method consists of two steps. First, a switched L∞-based descriptor observer attenuating the effect of uncertainties is designed to obtain simultaneous point estimate of the system state and the fault term. Second, interval estimation is achieved by integrating robust point estimation with zonotopic analysis techniques. The observer gains are calculated by solving Linear Matrix Inequality (LMI) derived using a common Lyapunov function.

Résumé | Liens | BibTeX | Étiquettes: @article{Bahhar2023, One of the most expensive and fatal natural disasters in the world is forest fires. For this reason, early discovery of forest fires helps minimize mortality and harm to ecosystems and forest life. The present research enriches the body of knowledge by evaluating the effectiveness of an efficient wildfire and smoke detection solution implementing ensembles of multiple convolutional neural network architectures tackling two different computer vision tasks in a stage format. The proposed architecture combines the YOLO architecture with two weights with a voting ensemble CNN architecture. The pipeline works in two stages. If the CNN detects the existence of abnormality in the frame, then the YOLO architecture localizes the smoke or fire. The addressed tasks are classification and detection in the presented method. The obtained model’s weights achieve very decent results during training and testing. The classification model achieves a 0.95 F1-score, 0.99 accuracy, and 0.98e sensitivity. The model uses a transfer learning strategy for the classification task. The evaluation of the detector model reveals strong results by achieving a 0.85 mean average precision with 0.5 threshold (mAP@0.5) score for the smoke detection model and 0.76 mAP for the combined model. The smoke detection model also achieves a 0.93 F1-score. Overall, the presented deep learning pipeline shows some important experimental results with potential implementation capabilities despite some issues encountered during training, such as the lack of good-quality real-world unmanned aerial vehicle (UAV)-captured fire and smoke images. © 2023 by the authors. |

However, radiologists often encounter difficulties when presented with cases of uncertain diagnoses as they struggle to find comparable cases in both public and internal databases to assist them in their decision-making. This manual search process not only detracts from the ability to diagnose new cases but also places a considerable burden on radiologists’ workflow. To tackle these challenges, this study suggests a computer-aided system that can automatically retrieve annotated medical images with similar content. This system incorporates a feature extractor based on deep learning, designed to simplify the process of identifying comparable images from an extensive chest radiograph database. The main focus of this study is on the feature extractor, which utilizes YOLOv5 and EfficientNet. YOLOv5 is known for its fast and efficient object detection framework, while the EfficientNet-B0 encoder block serves as an image retrieval and EfficientNet-B3 helps prevent noisy predictions. The study conducted experiments on a large dataset to evaluate the performance of the proposed solution. The results demonstrate that the model outperforms other classical approaches, with a mean average precision of 0.488 at a threshold of 0.9, which is higher than the performance of YOLOv5+ResNet, and EfficientDet of 0.234 and 0.257 respectively. Moreover, the model precision was significantly higher, with a precision of 0.864 for all pathologies, which was 0.352 higher than YOLOv5+ResNet and EfficientDet. Overall, the proposed computer-assisted system has the potential to enhance the efficiency of radiologists’ workflow by offering a more effective and efficient tool for retrieving similar annotated medical images. This study is a significant advancement in the development of intelligent and efficient image retrieval systems in the medical imaging field. The proposed solution has the potential to significantly impact the diagnosis of complex medical cases, particularly in emergency departments. © 2023 IEEE. |

The PAD-UFES-20 dataset is very relevant for this task since it contains 2,298 imbalanced skin lesions smartphone images. Thus, data sampling techniques such as Random Over Sampling (ROS) and SMOTE were applied to overcome this issue. This work is based on two scenarios. The first scenario aims to classify the whole six classes figuring in this dataset, using various powerful proposed methods based on Deep Learning (DL) models. The best performance was achieved when employing EfficientNetB0 with data ROS, as it reached an accuracy of 92.01%, F1-score of 92.01%, and AUC of 97.12%. The objective of the second scenario is to make a triage between two skin lesions: Melanoma and Nevus using DL techniques. The results of the use of an EfiicientNetB1 with data ROS demonstrated a high level of accuracy, F1-score, and AUC, with a measurement of 98.98%, 99.22%, and 99.95%, respectively. The study’s high-performance shows that these methods might have the potential to be a useful tool for clinicians in the examination and diagnosis of skin lesions, thereby enhancing the healthcare quality. © 2023 IEEE. |

Résumé | Liens | BibTeX | Étiquettes: @article{Benjemaa2023285, The main goal of this work is the fault tolerant control (FTC) for the uncertain neutral time-delay system with and without delayed input. For the uncertain neutral time-delay system with not delayed input, we consider the adaptive observer for the fault detection and estimation steps. For the case of delayed input system, we consider the robust stabilization to guarantee the stability of system in closed loop. Then, for the fault compensation step, the fault tolerant control law is the addition of two terms, the first one is the nominal control and the second is the additive control. Finally, simulation results are presented to prove the theoretical development. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. |

In NCS, the network must be viewed as part of the system and not just a means of communication. For this, two issues must be considered. The first consists of adapting the control and diagnostic laws to the performance of the network. The second is to guarantee the performance of the system. Each control loop containing a network is vulnerable to faults and cyber attacks and malicious users can intercept and listen to data during transmission. For that reason, it is essential to protect transmitted data against unauthorized access and modification and to diagnose components. In this paper, the authors presented a model with CPN of a NCS, the authors proposed a sensor fault detection and correction mechanism, then the authors injected a sensor fault and the authors tested the effectiveness of the proposed mechanism in detecting that fault and correcting its influence. Simulation results proved the success of the preventive mechanism in overcoming the influence of the fault and returning to normal behaviour. © 2022 The Authors.

Our research aims to speed up the diagnostic process, particularly in emergency situations where specialized medical personnel are not always available. Our technology includes a user-friendly interface that enables healthcare professionals to efficiently submit ultrasound scans of their patients’ thyroids. The images are then analyzed using integrated AI algorithms based on the YOLOv5 object detection model. In real-time, these algorithms efficiently and rapidly identify and localize thyroid areas. With an overall precision rate of 0.879 and a recall rate of 0.862, the results show a high degree of precision and recall. The average precision (mAP50) is 0.892, confirming the accuracy of localization.

These modifications make the system expandable in number of vehicles. That is to say, along its route, this platoon will send a aleatory call to all connected drivers, to join it. Each vehicle wishing to be part of this platoon must send a configuration and registration message and must provide the necessary information to be part of the platoon. This new feature can reduce traffic congestion and save energy. This article, paves the way for the emergence of a new type of driving system that we will call « EX-platoon »extensible platoon abbreviation. Thus, through this document, we will develop a model based on a Petri network describing the flow of messages exchanged between the different parts of this system necessary to allow the cooperative driving system to be extensible.

Magnetic Resonance Imaging (MRI) is a successful, highly sensitive MS lesion diagnostic technique. It is used to monitor the activity and progression of this disease. Monitoring the progression of multiple sclerosis (MS) is crucial for timely intervention and treatment adjustments, as it can help improve patients’ quality of life and contribute to ongoing research efforts to better understand the disease. This paper uses two techniques to monitor MS lesions progression: the Decimal Descriptor Pattern (DDP) and the Local Binary Pattern (LBP). These operators are used to extract the most important features and to characterize the properties of the structures in the brain. 3D MRI brain are described using a collection of orthogonal planes. We have developed an extension to the DDP descriptor to improve the performance in MS evolution. Our results are proof that our approach is effective and fast. © 2023 IEEE. |

As a key part of Industry 4.0, IoT has been widely used in various industrial fields. The integration of Blockchain and IoT technologies in Industry 4.0 plays an important role in improving the performance of systems in Industry. This integration improves classic deterministic interactions between industrial devices to become intelligent interactions. Blockchain is an advanced technology that leads to robust distributed applications. It is a tamperproof, decentralized, immutable and transparent database. In this paper, we present the principle of monetization as a principle of interaction between industrial objects.

IoT has the potential to transform industries and enable new forms of innovation and efficiency, but it also poses challenges in terms of privacy, security, and data management. As the number of connected devices continues to grow, it will be essential to develop standards and best practices to assure IoT system reliability and safety. To accomplish these obstacles of efficient data sharing and authorized access control, otherwise decentralized automation, security, and stakeholder trust management in the IoT, a new technology called Blockchain has emerged. In this context, this paper introduces Blockchain technology, which is characterized by decentralization, transparency, and immutability. It can be used to solve some of the challenges facing IoT systems, such as data security and confidentiality.

This is coupled with the application of Linear Least Squares (LLS) techniques. To execute this method, it is imperative to acquire highly accurate measurements of both torque and position at a high sampling frequency. Moreover, it is necessary to estimate velocities and accelerations by applying a band-pass filtering method to the positional data. Because of the presence of noise within the observation matrix and the iterative nature of the identification process, we have adapted the Instrumental Variable (IV) method to tackle the challenge of noisy observations. A recent successful application involved a novel identification approach called the Direct and Inverse Dynamic Identification Model (DIDIM), which relies solely on torque measurements as its input variables. The experimental findings demonstrate that the IV and DIDIM techniques yield comparable numerical results. In this paper, we undertake a comparative analysis of these two approaches using a double step least squares (2SLS) examination. To substantiate our findings, we carry out experimental validation using a 2-degree-of-freedom planar robot. © 2023 IEEE. |
