Non-Invasive Monitoring of Patient Movements and Scratching Behavior Using Piezoelectric Sensors R. Niranjana, R. Sarathkumar, Gokul Rajan V, Harish Ragavendar SN, Sasikanth S 2025 IEEE 1st International Conference on Innovations in Engineering and Next Generation Technologies for Sustainability Icinvents 2025, 2025 Monitoring patient movement is crucial for the diagnosis of sleep disorders, neurological diseases, and allergic reactions. But scratching a primitive, fundamental physiologic response has been largely ignored in medical evaluation.” In this study, we wanted to show that piezoelectric sensors can be used to monitor movements such as scratching and moving position without attaching anything to the patient. The system is a passive sensing system consisting of piezo-ceramic devices placed underneath the legs of a bed to detect the mechanical stress caused by body movements and convert it into electrical signals. Controlled experiments were used to validate the proposed approach, thereby ensuring scratching could be distinguished from other motions. The results suggest that this method is a robust, privacy-sensitive, and low-cost alternative to conventional video-based monitoring, allowing for continual patient surveillance in real-world context.
Impact of Breast Density on Early Breast Cancer Detection and Classification: A Comprehensive Survey with Emphasis on Mammography A. Ravi, R. Niranjana, Aishvarya Ravichandran, R R Thirrunavukkarasu, N. Thiyagarajan 2025 IEEE 1st International Conference on Innovations in Engineering and Next Generation Technologies for Sustainability Icinvents 2025, 2025 Breast density is a well-established risk factor in breast cancer detection and classification, significantly impacting the diagnostic performance of mammographic screening. High-density breast tissue reduces mammographic sensitivity, increasing the likelihood of false negatives while simultaneously elevating the probability of false positives. These challenges necessitate the integration of adjunctive imaging modalities such as ultrasound, magnetic resonance imaging (MRI), and artificial intelligence (AI)-driven methodologies to enhance detection accuracy in dense breast cases. This survey provides a systematic review of the role of breast density in early cancer detection, with a primary emphasis on mammography-based approaches, while critically analyzing the efficacy of complementary imaging techniques. We examine state-of-the-art advancements in digital mammography, tomosynthesis, and deep learning-based enhancements, evaluating their comparative effectiveness in mitigating density-related limitations. Furthermore, this work identifies current research gaps, technological constraints, and emerging trends in breast density-aware screening strategies, offering insights into future developments in precision diagnostics. This study serves as a technical reference for radiologists, AI researchers, and clinical practitioners aiming to optimize breast cancer detection methodologies.

Enhanced Skin Diseases Prediction using DenseNet-121: Leveraging Dataset Diversity for High Accuracy Classification R. Niranjana, T. Hemadarshana, S. Ilakkya, R.Santhana Krishnan, J.Jeniksha Epziba, T. Preetha Proceedings of the 3rd International Conference on Applied Artificial Intelligence and Computing Icaaic 2024, 2024 Skin disorders are a major worldwide health concern that require sophisticated diagnostic technologies for prompt and accurate identification. A deep learning approach that utilizes the DenseNet architecture for dermal image-based skin disease prediction is proposed. Creating and organizing a heterogeneous dataset covering a variety of skin conditions is part of the technique. Testing, verification, and training sets of the dataset are separated out to provide a thorough assessment of the model’s efficacy. Following its initial training on a large-scale dataset using pre-learned weights, the selected DenseNet model is refined using the skin disease dataset. Transferring expertise allows models to better identify relevant characteristics by utilizing information acquired from general photo recognition tasks. To adapt the architecture for the classification of skin diseases into many classes, custom layers are added. During the training phase, the model is optimized using suitable learning rates and loss functions. To reduce overfitting and improve the model’s generalization, hyperparameter adjustment is done. To assess the model’s performance, parameters like precision and loss are applied to the verification dataset. The model is evaluated on an alternative dataset to see if it can generalize to cases that haven’t been discovered yet once it has been successfully trained and validated. Throughout the process, patient privacy and data security are two of the most important ethical factors. The developed skin disease prediction model has the potential to be used in practical settings, facilitating prompt and precise diagnosis. Subsequent research endeavors could encompass ongoing enhancements to the model, cooperation with healthcare experts for clinical verification, and incorporation into user-friendly programs to ensure broad accessibility within healthcare environments.

Web3 technologies pin the inconvenience of Web2 as being too centralized, lacking in privacy, and problematic in terms of data ownership; Web3 can champion decentralized applications [or dApps] and smart contracts. Taking the key blockchain camps including Ethereum, Solana, and Polkadot into consideration, the study measures their effectiveness, operation capability, and security features. Success and failure rates of the decentralized architecture concept in response to problems affecting different sectors such as finance, healthcare, and digital ownership are measured by simulations as well as the case studies. Particular emphasis is created on such issues as scalability, legal requirements, and user acceptance. Application blockchains are audited by means of blockchain analytics tools and smart contract testing frameworks to identify the strengths and weaknesses of DApps in order to improve them. This research also points towards the issues that require focusing on the improvement of governance models, UX interfaces, and security frameworks in the Web3 sphere. By assessing the existing decentralized platforms and perform performance study, the research identifies the drawbacks and challenges of the blockchain platform and suggests probable solutions to tackle them. Thus, the study results indicate that decentralized web architectures as such have a rather high potential in the future, although the issues of scalability and usability will become the main factors to define their success.

Saravanakumar Proceedings of 5th International Conference on Iot Based Control Networks and Intelligent Systems Icicnis 2024, 2024 One essential natural resource, the air quality index has been deteriorated by economic activities. Many studies have been conducted about the forecasting of periods of unsafe atmospheric conditions; however, the majority of these studies are limited in their capacity to include seasonal and other factors due to insufficient longitudinal data. India noise pollution has compiled a 6-year dataset that has been used to build several prediction models. There are encouraging outcomes when AQI levels are predicted using machine learning methodologies such as support vector machines (SVMs) artificial neural networks (ANNs), and Naive Bayes (NB). However, in several tests involving datasets from three different locations, NB, ANN, and SVM performed well to maximize prediction performance. When it comes to mean absolute error (MAE), R-squared (R2), and Root-mean-square deviation (RMSE), the combined performance of stacks is unsurpassed. In the related work section, summarize the limitations of existing models, such as inadequate data preprocessing, low spatialtemporal resolution, limited feature selection, or overfitting in complex models. Highlight gaps in scalability, real-time adaptability, and generalization across regions, emphasizing the need for robust, efficient models tailored to air quality prediction.
