Spatial, temporal, and weather elements like ballast, loose nuts, misalignment, and cracks due to rain, snow, and earthquakes may lead to railway accidents and cause human and financial loss. Manual inspection is erroneous, labor-intensive, and *** automatic inspection provides a fast, reliable, and unbiased solution in this regard, however, ensuring high accuracy for fault detection is challenging due to the lack of public datasets, noisy data, high computer processing requirements, and inefficient models. This study presents an approach that uses Mel frequency cepstral coefficient features from the acoustic data. The dataset gathered using a customized railway cart from our previous research is used for experiments. The focus of the study is to increase the fault detection performance using selective features from the acoustic data. This study employs Chisquare(Chi2) for the selection of important features and involves performance analysis of machine learning and deep learning models using selected features. Experimental results suggest that using 60 features, 40 original features, and 20 Chi2 features, produces optimal results both regarding accuracy and computational complexity. A 100%accuracy can be obtained using the proposed approach with machine learning models. Moreover, this performance is significantly better than existing approaches.

Optical biosensors, a novel invention at the intersection of biotechnology and optics, are revolutionizing the field of biomedical diagnostics. Optical biosensors act by identifying variations in light's wavelength, phase, polarization, or intensity caused by interactions between a sensing element and the target analyte. Optical biosensors outperform other sensor types in sensing applications due to their quick, accurate, and extremely sensitive results. When evaluating optical sensors, total power, core power, efficient area, and indices are the most crucial variables to consider. Recent years have seen notable advancements in machine learning (ML), a branch of artificial intelligence (AI). This review investigates the complementary nature of optical biosensors and machine learning methods. Here, the potential utility of ML for optical biosensors is explored in detail. The advantages and drawbacks of the most popular machine learning methods are listed based on an analysis of the optical biosensing data. It highlights the possible effects of machine learning on improving the sensitivity, selectivity, and adaptability of optical biosensing devices, and it summarizes current advancements in the field. Finally, the study considers the challenges and limitations that associated with current optical biosensing techniques. © 2024 Bharati Vidyapeeth, New Delhi.

The main objective of this research is to utilize the technologies of cloud computing in the applications of the IoT. The IoT network is divided into three layers: the cloud computing layer, the edge layer, and the fog layer. More than twenty-five million devices are connected to the fog layer leading to an increase in data traffic in the network in general. As a result, there will be an increase in the number of attacks. Therefore, protecting the data of the IoT and detecting attacks are indispensable. Since new types of attacks frequently emerge, intrusion detecting systems (IDSs) have to be developed to counteract the new types of attacks. However, built upon the principles of deep learning and machine learning, most of the current IDSs are based on predicting the probability of an attack. The most commonly used IDSs are the KNN and the SVN. Such IDSs suffer from low accuracy rates in attacks detection, time consumption, and a large number of false alarms. Thus, this paper suggests a new model of deep learning that is built upon combining two algorithms: the convolution neural network (CNN) and the gated recurrent unit network (GRU). Additionally, two types of datasets are utilized: the NSL-KDD and UNSW-NB15. These datasets are categorized in accordance with multiclass classification. The suggested model provides a better detection rate in comparison with the other models. It achieves a detection rate that is 1.5 more accurate than the other IDSs. Also, it exhibits fewer false alarms, and it provides less time for detection rate. The achieved results of the suggested model are due to utilizing the technologies of deep learning and machine learning. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

This paper aimed to suggest a new Secured Hash Algorithm 3 (SHA-3) with seed value implementation. Seed worth ensuring that there are fewer expectations collisions, despite an attacker selecting the data. Furthermore, attackers who combine seed values with hash functions are prevented from exploiting the properties of a hash function to construct many security attacks, such as denial of service attacks and dictionary attacks. A novel approach to enhanced SHA-3 diffusion was proposed here by XORing the seed value with θ step result after transforming the seed bits into a 5 × 5 × 64 matrix and discarding the rest. © 2023 IEEE.

To fortify security mechanisms in software systems for the Internet of Things (IoT), this article presents a framework for AI-Enhanced Virtual Twin Modelling. In order to track and examine the actions of IoT devices in real-time, the suggested method makes use of virtual twin technology that is combined with machine learning techniques. Automated response generation, continuous threat assessment, and anomaly detection are made possible by creating a digital clone of the actual IoT network using the virtual twin paradigm. By combining deep learning models like CNNs and LSTMs, it becomes easier to forecast possible security risks in network traffic data by seeing intricate spatial and temporal patterns. When tested in a virtual Internet of Things (IoT) setting, the suggested framework outperforms conventional rule-based approaches by a wide margin, reducing reaction time by 35% while achieving an accuracy of 9 6. 2 %in threat identification. © 2024 IEEE.
