Bragg-type layered dielectric structure, which provides the Chebyshev character of the behavior of the reflection frequency response, was considered. To obtain a fractional-rational representation of the structure frequency response, method of synthesis of the type I Chebyshev filter was used. An approach for mapping the entire equiripple domain of Chebyshev polynomial onto the specified reflectionless band and determining scale parameter are proposed. A modification of the periodic Bragg-type layered structure is demonstrated, which provides a reflection frequency response with minimum ripple level in the passband while preserving the location of the zeros that delimit the reflection band of the structure. © 2023 IEEE.

The quality control of printed circuit boards (PCBs) is paramount in advancing electronic device technology. While numerous machine learning methodologies have been utilized to augment defect detection efficiency and accuracy, previous studies have predominantly focused on optimizing individual models for specific defect types, often overlooking the potential synergies between different approaches. This paper introduces a comprehensive inspection framework leveraging an ensemble learning strategy to address this gap. Initially, we utilize four distinct PCB defect detection models utilizing state-of-The-Art methods: EfficientDet, MobileNet SSDv2, Faster RCNN, and YOLOv5. Each method is capable of identifying PCB defects independently. Subsequently, we integrate these models into an ensemble learning framework to enhance detection performance. A comparative analysis reveals that our ensemble learning framework significantly outperforms individual methods, achieving a 95% accuracy in detecting diverse PCB defects. These findings underscore the efficacy of our proposed ensemble learning framework in enhancing PCB quality control processes. © 2024 IEEE.

This paper describes a self supervised representation learning approach that can perform robust object detection in out-of-distribution rotated images for autonomous driving task. Keeping in mind the limitations of vehicle sensors we incorporate self-supervised rotation invariance for correcting rotational corruptions. We present a comprehensive analysis of observed label shifts, validate the results using holdout sets and provide explainability for the performance uisng GradCAM appaorach. We demonstrate results on real-world adversarial examples: (Autonomous Scenes - DAWN dataset) that significantly outperform common methods. The proposed framework outperforms the rotation-affected benchmark by 14.73 points of mAP for the OD task in autonomous driving applications. ©2024 IEEE.

The use of insecure implementations of cryptographic systems makes encrypted communications vulnerable to practical attacks. Today, attacking, i.e. testing implementations requires human labour and an understanding of the cryptographic system. Automated systematic testing can reduce the insight needed to discover faulty implementations. The approach presented in this paper employs neural networks as the core of a universal framework for cryptographic attacks on arbitrary black-box encryption schemes. The framework trains a neuronal network to automatically perform decryption of ciphertext without knowing the corresponding decryption key. The network approximates the decryption function by encrypting randomly generated plaintext using an arbitrary encryption function and attempting to learn the relationship between plain-and ciphertext. If the decryption function for a certain key is successfully approximated by the framework, the plaintext of any message encrypted with this key can be restored.

Vehicular Ad Hoc Networks (VANETs) are a type of wireless communication network that enable vehicles to communicate with each other and with roadside infrastructure in a peer-to-peer fashion;despite their vast applications, they come with several shortcomings. The key challenges in their real-world implementation include scalability, connectivity, and coverage issues. Unmanned Aerial Vehicles (UAVs), also known as drones, can complement existing VANETs in several ways to enhance their functionality and address some of their limitations. This paper studies the incorporation of UAVs in VANETs to overcome the challenges faced by the present networks. The approach is based on the dynamic deployment of UAVs in the most optimal positions, found by utilizing Particle Swarm Optimization (PSO) and Ant Colony algorithms which analyze the vehicle density, and previous coverage information in the network. The deployment of UAVs is intended to provide a seamless network coverage for ground vehicles. The impact of dynamic UAV mobility in communicating VANETs is comparatively studied. The simulation is done using Network Simulator-3 (NS3) simulator to evaluate the performance of 4 VANET protocols, AODV, DSR, OLSR, and DSDV, in terms of packet delivery ratio (PDR), Average End-to-End Delay, Throughput, Average Throughput per Packet, Packet Drop Rate, and Normalized Routing Load after incorporating the proposed modification designs. The paper concludes that the incorporation of Ant Colony is better suited to enhance VANETs than PSO. © 2024 IEEE.

The rapid growth of digital technology implies the progress of industry, by utilizing Industrial Internet of Things and Digital Twins, in collecting data through sensors and digitally monitoring and testing a product, with a view to improving its features, before the production of the physical product, in real world. At the same time, industrial carbon emissions are a major issue to be confronted. Since, Digital Twin is a connection between the physical and digital world, transferring data bidirectionally and providing insights into the lifecycle of a production process, it also can be utilized for the reduction of industrial carbon emissions. In this paper, we implement a method for the reduction of carbon emissions, by applying the Industrial Internet of Things to collect past data from manufacturing factors and a Digital Twin architecture to monitor present data, compose a model and predict its future behavior, considering renewable energy resources and less carbon emissions. This method contributes in improved decision making regarding the manufacturing process and energy efficient industrial operation. © 2022 IEEE.

Smart Agriculture (SA), a pivotal component of Industry 4.0, has revolutionized the agricultural sector by harnessing advanced technologies to optimize crop production, resource utilization, and environmental sustainability. However, integrating intelligent systems, particularly in Smart Irrigation (SI), introduces a complex network of interconnected assets susceptible to various failures. The realization of Industry 4.0’s potential in agriculture relies on the ability to detect and address these failures. This paper introduces the challenges and potential pitfalls encountered by SA, focusing on the critical domain of SI systems, notably concerning Water Pump failures and anomalies. We propose an innovative approach that combines both failure detection and anomaly detection in SA. By leveraging ML algorithms, we aim to develop tools capable of not only detecting failures but also detecting anomalies in irrigation systems and other vital components. Our interdisciplinary approach presents a clear roadmap to strengthen SA’s resilience and promote sustainable growth in the ever-changing landscape of Industry 4.0.

Due to the growing number of cloud users working on various cloud apps on specific infrastructure, resource allocation in cloud computing is implicitly difficult. Most resource allocation strategies currently in use focused on delivering efficiency determined by the workload of applications across many domains, such as business and scientific. Cloud service brokers compete strongly with one another to provide quality of service improvements based on the need, demand and the rapid growth of the services that are offered. Such conflict makes it difficult and complex to provide simple service selection and composition services in the cloud, this needs to be addressed to lighten the load on local resources. Because cloud-based services are too sophisticated and scalable, it is preferable to use an optimization strategy to choose the services that will meet the needs of the clients. To do this, a hybrid algorithm Modified Ant Colony System Cloud Services Composition (MACSCSC) is proposed to employ Ant Colony Optimization (ACO) incorporated with Genetic Algorithm (GA) to smoothly increase cloud-based services. When allocating cloud resources these meta-heuristic algorithms can achieve significantly better performance, lower costs and instances, better utilization of resources, and increased energy efficiency. The empirical findings on different real datasets have been demonstrated to show the improvements of the suggested method to overcome the drawbacks such as allocation of resources and high power consumption. © 2024 IEEE.
