An Efficient Method for Object Detection with Automatic Illumination Correction

Recent advancements in artificial intelligence and computer vision have led to the automation of many conventional surveillance techniques, especially in smart city applications. However, object detection systems often struggle in poorly lit environments and may suffer from slow processing speeds. To address these restrictions, this paper proposes an adaptive illumination correction technique using an enhanced Logarithmic Image Processing model. The method improves object visibility in low-light video frames and enhances detection performance. Additionally, a customized deep convolutional neural network is developed to accurately detect objects after applying the illumination correction. The combined framework is evaluated on standard datasets and demonstrates superior robustness to varying illumination conditions compared to existing state-of-the-art methods. The results show significant improvements in metrics such as accuracy, recall, precision, and F-measure, proving the effectiveness of the proposed approach.

Random Forest Algorithm based on Life Assessment and Reliability Test Procedures for Relays used in Circuit Breaker Operating Mechanisms

The essential parts of the circuit breaker working system is the relay which is susceptible to performance deterioration when operating in extreme conditions like salt spray. This can eventually impair the circuit breakers functionality and compromise the power system's ability to function effectively and consistently. This study used an existing test structure to conduct rapidly deteriorating tests on a specific design of additional switch under salt spray in order to assess the relay's lifetime condition effectively. As distinctive parameters impacted by salt spray, contact resistance, pickup voltage, release voltage, pickup time, release time and coil resistance of the relay were examined. The results demonstrated that the presence of salt spray reduced the coil effectiveness of the relay, necessitating a higher operating voltage in order to supply the electromagnetic force required for functioning. Moreover, actual and predicted lifetime from individual parameter is calculated. However, coil deterioration also led to a reduction in the electromagnetic force that the step voltage produced, which lengthened the operating period. A Random Forest algorithm model was then created that was appropriate for determining the relay status in this investigation. The existing Gradient Boosting, XGBoost algorithm is compared with proposed method to analyze the performance metrics such as accuracy, precision, recall, F1-score, R2 score, specificity, sensitivity, Root Mean Square Error (RMSE) and Mean Absolute Error (MAE) is determined.

Accurate and efficient road obstacle detection is crucial for ensuring the safety and reliability of autonomous and assisted driving systems. However, current object detection models, including YOLOv8, often encounter difficulties in accurately detecting small obstacles and balancing detection precision with inference speed. To address these challenges, we propose an improved YOLOv8-based detection framework featuring three key enhancements: (1) the backbone is redesigned using RepVGG modules to accelerate inference through structural re-parameterization without compromising feature representation; (2) an additional small-object detection head at the P2 feature level is introduced to significantly enhance sensitivity towards small-scale obstacles; (3) a Swin Transformer module is integrated into the final stage of the backbone to improve global contextual understanding and semantic feature extraction. Extensive experiments conducted on a comprehensive, multi-source road obstacle dataset demonstrate that our proposed model achieves superior performance with a precision of 0.812, recall of 0.782, mAP@0.5 of 0.822, and mAP@0.5:0.95 of 0.588. Additionally, it maintains a real-time inference speed of 180 FPS on an NVIDIA H800 GPU. The results confirm the efficacy of our approach, particularly in enhancing small object detection in complex real-world traffic scenarios.

Passive Voltage Regulation System for Remote Power Tapping from High-Voltage Transmission OHGW

It is a real challenge to bring reliable and stable power to remote locations, critical facilities such as telecommunication towers, because it is costly and challenging to expand the conventional power distribution networks. In this paper, a new power supply system is proposed that can overcome this problem by exploiting common overhead ground wire (OHGW) energy transmission lines that run high-voltage (HV). The principle of action is that the system isolates a portion of the OHGW and applies an alternating current (AC) voltage to it by capacitively coupling it to the phase conductors of a transmission line. To take an example, a 4-km span of OHGW on a 735 kV line can produce a maximum power of 25 kW of power which is modelled as a 52.4 kV Thevenin source with the capacitive impedance as 26nF. The main problem is to achieve a stable output voltage (within 5%) across a large load range (0 to 25 kW) without the need for complex control systems, power electronics and so on. To obtain good regulation, this problem is solved using a mix of passive components, nonlinear inductances, and a unique magnetic component, IVACE. Simulation studies have proved that the system could sustain a load voltage of about 62 kV, and the system would be fault resistant and could recover fast with a load disturbance. Harmonic analysis: The value of the total harmonic distortion (THD) is 6.5 per cent at no load and 4.7 per cent at nominal load, with the third harmonics as the most important factor. This method has the advantage as compared to other means of power supply to remote regions, where expansion of the HV transmission network is not needed, and the method is a low-cost and low-maintenance method that can be implemented quickly.

Remaining Useful Life Prediction of EV Lithium-Ion Batteries Using TG-AMF Enhanced MTS-BiLSTM Optimized with Walrus Algorithm

Predictive maintenance is essential to industrial operations, especially in lithium-ion battery systems. Remaining Useful Lifetime (RUL) prediction is the most accurate means of maintaining optimal performance and avoiding unexpected failure in these systems. Noisy sensor data and complex degradation patterns, however, make the task complex and require sophisticated techniques for proper analysis and forecasting. Hence, this manuscript proposes an optimized Electric Vehicle (EV) lithium-ion battery RUL prediction using a multi-time scale bidirectional Long Short-Term Memory (MTS-BiLSTM) Network. Initially, input data is taken from the Remaining Useful Lifetime Prediction Dataset available on Kaggle, containing sensor readings and operational parameters for systems under degradation. It uses the trimmed global adaptive mean filter approach (TG-AMF), which enhances input data quality by removing general noise and preserving the essential feature points related to degradation patterns. A novel MTS-BiLSTM network approach is proposed for predicting RUL by capturing both Proximal correlations and Delayed dependencies in data to model trends accurately. Hyperparameters of the proposed model are optimized via the Walrus Optimizer (WO), which improves prediction and computation overhead. The robustness of the proposed framework is analyzed through benchmarking with performance metrics coefficient of determination (R2), root mean square error (RMSE), mean absolute error (MAE), mean absolute percentage error (MAPE), prediction horizon accuracy (PHA), and computation time (CT). The overall PHA of 98%, MAE of 17.04, MAPE of 8.63, CT of 7.57s, and RMSE of 5.83 are obtained by the proposed method of forecasting the battery RUL for EVs

Optimizing Beamforming in Massive MIMO Systems Using Machine Learning Approaches: A Comprehensive Review

The development of the Massive Multiple-Input Multiple Output (MIMO) system in recent years has revolutionized wireless communication, delivering significant benefits to energy and spectrum efficiency. While these strategies have been instrumental in the continuous evolution of system performance, traditional static beamforming methods (e.g. Zero-Forcing (ZF), Maximum Ratio Transmission (MRT) and Minimum Mean Square Error (MMSE)) are limited concerning their scalability and reliability on channel state information to a large extent. In this paper, we investigate the techniques of beamforming with machine learning (ML) integration to bypass these limitations and better optimize system performance. This review covers the usage of different approaches to Machine Learning: supervised learning methods (including Neural Networks and Support Vector Machines (SVM). We also study reinforcement learning techniques due to their dynamic optimization features, as well as deep-learning models like Recurrent and Convolutional Neural Networks (RNN/CNN), which are popular for treating big data or temporal dynamics. Our analysis shows several key findings: ML-based methods are effective in improving the performance of beamforming, including enhancing spectral efficiency and reducing energy consumption as well as their robustness with respect to channel state information (CSI) errors. Finally, we conclude by identifying how potential emerging trends such as federated learning and quantum computing can be positioned to overcome these challenges in the future direction of ML-optimized beamforming for massive MIMO systems.

Mitigating in Band Overshoot in Digital High-Pass Filters: Design and Analysis of Bessel and Gaussian Filters for Maximally Flat Step Response

Digital high-pass filters play an important role in transcending the low-frequency noise to maintain the signal integrity in several modern applications of communication systems. The most important distinction between them is the attempt to obtain a flat step response and a minimum of distortion in the amplitude-frequency response (AFR). The trade-off between flat step response and the minimum amplitude-frequency response distortion in IIR high-pass filters generated by bilinear transformations of Bessel and Gaussian low-pass prototypes is explored in this paper. The proposed design uses a parallel structure, subtracting the amplitude-frequency response of the low-pass filter from the direct pass AFR to eliminate step response overshoot without sacrificing time-domain flatness. Filter performance is validated and overshoot behavior quantified using numerical evaluations performed in the Mathcad environment. Comparison of various filter orders in parallel and stage-by-stage connections shows that Gaussian-based HPFs have minimal negative step overshoot (as low as –0.002%) compared to Bessel-based filters (e.g., –0.37% for 8th order). However, AFR overshoot increases with order (72% for Gaussian, 78% for Bessel). The parallel scheme reduces the AFR overshoot by up to 30% over the conventional schemes without degradation in transient response and results in robust low-distortion filters in real-time detection applications.

Design of Sliding Mode Controller Combined with Nonlinear Disturbance Observer for Trajectory Tracking of Mobile Robots in Mixed Terrain

Accurate trajectory tracking is a fundamental yet challenging requirement for mobile robots, especially when operating on surfaces with varying frictional characteristics (mixed terrain) and subjected to external disturbances as well as model uncertainties. This study presents the design and evaluation of an integrated control strategy aimed at enhancing trajectory tracking performance under these demanding conditions. A Sliding Mode Controller (SMC), known for robustness but prone to chattering, was integrated with a Nonlinear Disturbance Observer (NDO). The NDO was designed to estimate lumped disturbances encompassing varying friction, model errors, and other external disturbances; this estimate was then used for compensation within the SMC control law to reduce the switching component's amplitude. The effectiveness of the proposed SMC-NDO method was verified through simulations on a mobile robot model following a reference trajectory in a simulated mixed terrain environment under various disturbance conditions. Simulation results showed that the proposed SMC-NDO controller significantly improves trajectory tracking accuracy and reduces chattering compared to the traditional SMC controller and a PID controller. The integration of the NDO with SMC proves to be an effective approach for improving mobile robot trajectory tracking, enhancing accuracy and robustness while mitigating chattering in challenging environments with varying terrain and disturbances.

Chest X-ray Abnormality Detection Using Convolutional AutoEncoder Combined with Double Generative Adversarial Network (GAN)

The statistical properties of aberrant samples are unstable, and traditional chest X-ray image data is difficult to gather and unevenly distributed. A CAE-D-GAN anomaly detection model based on dual GANs and convolutional autoencoders is proposed in this paper. We employ the DGAN module to obtain clear degraded images, the convolutional autoencoder to extract low-dimensional features from high-dimensional data, and the DDGAN module to learn how to degrade images and recover clearer images from degraded photos during the adversarial process. While the reconstruction error score identifies sample flaws, the network is optimized by the error loss between the original and reconstructed samples. The network just needs normal samples to be trained, and it can reach a maximum AUROC value of 0.86. The findings demonstrate that the CAE-D-GAN model outperforms a number of different anomaly detection models in terms of detection effects and feature reconstruction capabilities. There are special opportunities for using this approach to detect other anomalies in medical images.

Minimization of Transmission Congestion Cost using P-OPF based LSF, PSO and ANN Techniques

The inclusion of renewable energy sources (RES) into a stabilized network has opened gates to numerous optimization problems. Optimization of RES generation might not imply merely the myth of high availability but it is furthermore fenced by parameters such as transmission line power flow patterns, having the optimized location, bus nodal pricing (LMP), congestion scenario, congestion cost and reliability margins of the system (ATC,TRM). Integration of RES also drags towards the congestion episode within the transmission system. The uncertain behavior of renewable energy initiates uncertainty into the system from generation perspective. These uncertainties lead to congestion which alters the linear sensitivity factors (LSF), LMP and reliability margins of the network. The congestion scenario may jeopardize the security of transmission network hampering the limits of transmission lines. The change in marginal values reflects the occurrence of congestion with additional congestion cost. Different optimization tools have been introduced in order to optimize various objectives like optimization of generation, rescheduling generators, load curtailment etc. In this work we have presented optimization of congestion cost (i.e. Congestion Management in terms of economics) post inclusion of uncertain RES (here wind and solar source are considered) into the system. The optimization problem is resolved using Probability Optimal Power Flow (P-OPF) based Particle Swarm Optimization (PSO) technique in MATLAB-MATPOWER software with Area Based Congestion Management (ABCM).

A Smart AI-Based System for Emergency Vehicle Prioritization in Urban Traffic

Prioritizing and taking the necessary procedures to ensure human safety is critical. One of the many challenges we face in modern life is the increased risk of traffic congestion. Congestion on the streets may be problematic in large cities, especially for emergency vehicles such as fire engines and ambulances. Traffic delays are caused by a range of factors, including the weather, the time of day, the season, and unexpected occurrences such as accidents or construction projects. This creates delays in responding to emergencies, which leads to several deaths. A traffic control system limits the number of cars that can pass on a route without colliding with or impeding traffic flow. To minimize traffic congestion, a busier lane requires a longer green light than others. Systems with large traffic volumes require an adaptive system with traffic density control capabilities. A generic traffic control system may struggle to distinguish between emergencies and high-priority scenarios. This project proposes an intelligent traffic control system that prioritizes emergency vehicles utilizing artificial intelligence and image processing to address this issue. This allows these automobiles to drive through busy regions of traffic without stopping. The ESP32-CAM used in this project captures images of vehicles and then uses AI and an image processing-based model to detect emergency vehicles (Ambulances). If it identifies the presence of any emergency vehicle, the corresponding lane will be cleared till the vehicle passes the signal point. After the emergency vehicles pass the road, the system will return to normal mode.
