Wireless Sensor Networks (WSNs) have become a fundamental component of modern monitoring and data acquisition systems, supporting applications such as environmental surveillance, healthcare monitoring, industrial automation, military operations, and smart city infrastructures. Despite their widespread adoption, WSNs remain highly vulnerable to various security threats due to their distributed architecture, limited computational resources, and deployment in unattended environments. Among these threats, clone attacks represent one of the most severe security challenges, where an adversary captures a legitimate sensor node, extracts its credentials, and creates multiple replicas that are subsequently deployed within the network. These cloned nodes can disrupt network operations, compromise data integrity, launch routing attacks, and facilitate unauthorized access to sensitive information. Consequently, the development of efficient and reliable clone detection mechanisms is essential for maintaining the security and functionality of wireless sensor networks. This paper proposes an intelligent clone attack detection framework designed to identify replicated sensor nodes while minimizing energy consumption and memory overhead. The proposed approach combines node identity verification, location-based monitoring, neighbor information analysis, and anomaly detection techniques to accurately identify suspicious node behavior. Relevant network parameters, including node mobility patterns, communication frequency, packet transmission characteristics, and neighborhood consistency, are analyzed to distinguish legitimate sensor nodes from cloned replicas. The framework incorporates lightweight processing mechanisms and optimized data structures to ensure efficient operation within the resource-constrained environment of wireless sensor networks. Experimental evaluation demonstrates that the proposed clone detection framework achieves high detection accuracy, low false alarm rates, and reduced communication overhead compared with conventional detection schemes. The system effectively identifies clone attacks while preserving network lifetime through energy-aware operations and memory-efficient storage management. Furthermore, the framework exhibits strong scalability and adaptability across varying network sizes and deployment conditions. The results indicate that the proposed method provides a secure, lightweight, and practical solution for protecting wireless sensor networks against clone attacks while maintaining efficient resource utilization. The framework contributes to enhancing network reliability, security, and operational longevity in modern wireless sensing applications.

The growing demand for sustainable and decentralized energy generation has intensified research on Vertical Axis Wind Turbines (VAWTs) due to their ability to operate efficiently under low wind speed and multidirectional wind conditions. Blade geometry plays a crucial role in determining the aerodynamic performance and power extraction capability of VAWTs. This study presents an experimental investigation of twisted vertical axis wind turbine blades based on NACA 4-series airfoil profiles to evaluate their influence on turbine performance. Several twisted blade configurations were designed and fabricated using selected NACA 4-series airfoils, while maintaining identical rotor dimensions and operating conditions. Experimental testing was conducted in a controlled wind tunnel environment over a range of wind velocities to measure rotational speed, torque, power output, and coefficient of performance. The results demonstrate that the incorporation of blade twist significantly enhances aerodynamic efficiency by improving the angle of attack distribution along the blade span and reducing dynamic stall effects. Among the tested configurations, the optimized twisted blade exhibited superior performance, achieving higher rotational speed, increased power coefficient, and improved self-starting characteristics compared to conventional straight-bladed designs. The experimental findings indicate that twisted NACA 4-series blades can effectively increase energy capture and operational stability, particularly under variable wind conditions. The study confirms the potential of blade twist optimization as a practical approach for improving the performance of small-scale vertical axis wind turbines. The outcomes provide valuable insights for the design and development of efficient VAWT systems for renewable energy applications, contributing to enhanced energy harvesting and sustainable power generation.

Black cotton soil is one of the most problematic expansive soils encountered in geotechnical engineering due to its high swelling and shrinkage characteristics, low bearing capacity, and significant volume changes under varying moisture conditions. These properties often lead to structural distress in pavements, foundations, embankments, and other civil engineering structures. Soil stabilization has therefore become an essential technique for improving the engineering performance of black cotton soil. In recent years, the utilization of agricultural and industrial by-products for soil stabilization has gained considerable attention owing to their economic and environmental benefits. Among these materials, bagasse ash, a waste product generated from sugar industries, has emerged as a promising stabilizing agent due to its pozzolanic properties and silica-rich composition. This study investigates the influence of bagasse ash and selected additives on the strength characteristics of black cotton soil. Various soil mixtures were prepared by incorporating different percentages of bagasse ash along with suitable additives to enhance the stabilization process. Laboratory tests were conducted to evaluate important engineering properties, including compaction characteristics, unconfined compressive strength, California Bearing Ratio (CBR), and shear strength parameters. The results indicated that the inclusion of bagasse ash significantly improved the strength and stability of black cotton soil by reducing plasticity and enhancing soil particle bonding. Furthermore, the addition of stabilizing additives accelerated pozzolanic reactions, resulting in improved load-bearing capacity and increased resistance to deformation. The experimental findings demonstrated that an optimum combination of bagasse ash and additives produced substantial improvements in soil strength compared to untreated black cotton soil. The stabilized soil exhibited higher compressive strength, enhanced bearing capacity, and improved durability characteristics, making it suitable for geotechnical and pavement construction applications. The study confirms that bagasse ash, when combined with appropriate additives, can serve as an effective, economical, and environmentally sustainable material for black cotton soil stabilization while promoting the beneficial utilization of agricultural waste products.

Rapid urbanization and the exponential growth of vehicle ownership have led to severe traffic congestion in metropolitan areas worldwide. Conventional road infrastructure and fixed lane management systems often fail to adapt to dynamic traffic conditions, resulting in inefficient road utilization, increased travel times, fuel wastage, and environmental pollution. Intelligent Transportation Systems (ITS) have emerged as effective solutions for addressing these challenges through the integration of sensing, communication, automation, and real-time traffic management technologies. Among these solutions, movable road divider systems offer a promising approach for dynamically reallocating road space based on prevailing traffic demands. However, traditional movable divider systems generally lack real-time monitoring, autonomous decision-making, and remote control capabilities. This study presents an IoT-Enabled Intelligent Movable Road Divider for Dynamic Vehicular Traffic Management and Congestion Reduction. The proposed framework integrates Internet of Things (IoT) technology, wireless communication networks, traffic sensors, cloud-based analytics, and automated actuator mechanisms to dynamically adjust road lane configurations according to real-time traffic conditions. Traffic density data are continuously collected using smart sensors and transmitted to a centralized control platform where intelligent algorithms analyze traffic patterns and determine optimal divider positions. Based on these decisions, motorized movable dividers automatically reconfigure lane allocations to accommodate varying traffic volumes in different directions. The proposed system enhances traffic flow efficiency by reducing congestion, minimizing vehicle waiting times, optimizing lane utilization, and improving emergency vehicle movement. Real-time monitoring and remote management capabilities enable transportation authorities to respond effectively to traffic fluctuations and incident conditions. Experimental evaluation demonstrates significant improvements in traffic throughput, reduced average travel time, lower vehicle queue lengths, and enhanced road utilization efficiency compared with conventional fixed-divider systems. The integration of IoT-based sensing and intelligent control mechanisms provides a scalable, cost-effective, and adaptive solution for smart city transportation infrastructure. The proposed framework contributes toward the development of intelligent traffic management systems capable of improving urban mobility, reducing fuel consumption, and supporting sustainable transportation objectives.

The developed framework incorporates data preprocessing, feature normalization, and deep neural network architecture to improve prediction accuracy and model generalization. The model is trained and evaluated on a benchmark cardiovascular dataset, where its performance is assessed using standard evaluation metrics such as accuracy, precision, recall, F1-score, and area under the receiver operating characteristic curve (AUC-ROC). Experimental results demonstrate that the proposed deep learning model outperforms several conventional machine learning techniques in identifying high-risk individuals. The system effectively captures complex nonlinear relationships among clinical variables, leading to enhanced diagnostic reliability and reduced false predictions. The findings indicate that deep learning can serve as a valuable decision-support tool for healthcare professionals, facilitating timely intervention and personalized treatment planning. The proposed approach contributes to the advancement of intelligent healthcare systems by enabling early risk identification, improving patient outcomes, and supporting preventive cardiovascular care.
