Ugale sharadugale1983@gmail.com Dinkar P. Patil sdinkarpatil95@gmail.com <p>In this paper, we are presenting the new broad essential transform called the Sharad transform. Additionally, we demonstrated a few theorems and properties, similar to the linearity property and the convolution theorem. Additionally, we fostered a connection between the new transform and another old useful transform, similar to the Laplace transform, the Sumudu transform, the natural transform, the Elzaki transform, the Abhoodh transform, the Formable transform, and so forth. Here we presume that these transforms are the extraordinary instances of the new broad basic transform, the Sharad transform. This transform is applied to ordinary differential equations and partial differential equations. This transform will be utilised in the future to tackle a lot more the ordinary differential equations, the partial differential equations, integro-differential equations, fractional differential equations, difference equations, differential-difference equations, and so forth.</p> 2024-12-15T00:00:00+00:00 Copyright (c) 2025 Communications in Mathematics and Applications https://rgnpublications.com/journals/index.php/cma/article/view/3260 Multi-Label Classification for Drift Detection in IoT Data Streams 2025-07-01T06:41:30+00:00 Mashail Althabiti malthabiti0001@stu.kau.edu.sa Manal Abdullah maaabdullah@kau.edu.sa Omaima Almatrafi oalmatrafi@kau.edu.sa <p>With the prevalence of <em>Internet of Things</em> (IoT) systems, data is exponentially growing, resulting in data streams. Data streams are massive, potentially non-stop, and arrive at high speed. These systems process IoT data streams in a non-stationary manner, making them susceptible to concept drift occurrence and class imbalance. Concept drift occurs as a result of the change in the underlying distribution over time, while class imbalance occurs when some class distribution is uneven. This paper proposes an <em>Implicit Drift Detection model with Multi-Label kNN</em> (IDD-MLkNN), aimed at addressing concept drift in multi-label classification for IoT data streams. While the model is applicable across various domains, its performance was specifically assessed using two IoT datasets — Bot_IoT and Edge_IIoTset — associated with intrusion detection systems. Applying the proposed model to oversee IoT network traffic offers practical advantages, potentially reducing the time and expenses of re-examining attack data. The evaluation was conducted for sudden and gradual concept drift scenarios. Experimental results show the superiority of the IDD-MLkNN over other well-known multilabel classification models in different performance measures such as the Subset Accuracy, Accuracy, Hamming Score, and F-measure. However, it was less efficient in terms of Evaluation Time compared to other multi-label classification methods.</p> 2024-12-15T00:00:00+00:00 Copyright (c) 2025 https://rgnpublications.com/journals/index.php/cma/article/view/3272 Certain Classes of Meromorphically Univalent Functions Associated With Subordinaion and Inclusion Relations 2025-07-09T10:52:51+00:00 Krisn Pratap Meena kpsgdm@gmail.com Indu Bala Bapna bapnain@yahoo.com <p>In this present paper, we introduce some new classes of Meromorphic function in punctured unit disk involving integral operator.

Pavithra pavithracshekar5@gmail.com M. Saradha ishuharisri88@gmail.com <p>The K-Nearest Neighbors (K-NN) is a supervised machine learning algorithm, specifically within the realm of classification and regression tasks. It is a simple yet powerful method used for making predictions based on similarities between data points. The fundamental idea behind K-NN is to classify or predict a new data point's label or classify by looking at the labels of its nearest neighbors in the training dataset. This research introduces an adaptive K-NN classification approach that leverages local data characteristics to dynamically adjust neighborhood size and distance metrics. This adaptive K-NN classification approach is thoroughly examined through comparisons with \(k=3\), \(k=5\) and \(k=7\). By adjusting neighborhood size and distance metrics, the study yields nuanced performance insights. Calculated outlier-to-class distances offer valuable adaptability indications. The experimental results showcase its potential to enhance classification accuracy and adaptability in diverse data scenarios. This method contributes to the advancement of K-NN based classification techniques and provides a promising direction for improving the efficiency of data classification tasks in real-world applications.</p> 2024-12-15T00:00:00+00:00 Copyright (c) 2024 https://rgnpublications.com/journals/index.php/cma/article/view/3279 Exploring Explainable AI (EXAI) – An Emerging Trend in Healthcare Sector 2025-07-15T10:03:14+00:00 Chaitali Pal cpal134@gmail.com M. Yashvanth yashu.yashvanth2@gmail.com K. S. Srinivasa Rao srinirao35@gmail.com <p>Industry 4.0 and COVID-19 drove businesses to adopt AI/ML amid VUCA, advancing toward Industry 5.0. Explainable AI (EXAI) fosters trust in healthcare’s digital shift, enhanced remote care, and chronic-disease management, ushering smarter decisions and better patient outcomes. The authors used snowball sampling via Google Forms, surveying hospitals, practitioners, vendors, and customers on healthcare technology adoption. Data were visualized and analyzed descriptively. Explainable AI (EXAI) shows significant promise in managing NCDs, with ML tools aiding better diagnosis and treatment. Once EXAI is integrated nationwide in healthcare, Indian businesses will pivot, analyzing new challenges, enabling data-driven solutions that enhance well being and innovation.</p> 2024-12-15T00:00:00+00:00 Copyright (c) 2024 https://rgnpublications.com/journals/index.php/cma/article/view/3280 Results on Invariant Submanifolds of Hyperbolic Kenmotsu Manifolds 2025-07-15T11:04:14+00:00 C.

Mary Priya Dharsini priyairudayam@gmail.com P. Joselin Lavino josline.lavino@gmail.com <p>The dislocated quasi \(b\)-multiplicative metric space is introduced as an extension of dislocated quasi \(b\)-metric space, which is demonstrated some well-known fixed point theorems and shows fixed point results for a contraction of rational type. Specifically, we generalize the convex contraction to encompass the dislocated quasi \(b\)-multiplicative setting. The results of this study not only contribute to the theoretical foundations of fixed point theory but also offers a new perspective on the applicability of dislocated quasi \(b\)-multiplicative metric spaces.</p> 2024-12-15T00:00:00+00:00 Copyright (c) 2024
