Abstract: Industrial motors and rotating machines play a vital role in manufacturing and production environments, where unexpected failures can lead to significant downtime, financial loss and safety risks. Traditional maintenance approaches such as reactive maintenance, performed after a failure and preventive maintenance, based on fixed time intervals are inefficient and often fail to detect early- stage faults. Existing monitoring systems are expensive, complex and mostly suitable only for large-scale industries, making them inaccessible for small and medium enterprises. Hence a low-cost ESP32-based predictive maintenance system for real-time condition monitoring of industrial motors continuously monitors key health parameters such as vibration, temperature and current using multiple sensors. By analyzing these parameters in real time, the system can detect abnormal operating conditions at an early stage. Fault severity is classified into normal, warning and critical levels, which are indicated using visual LED alerts. In addition, the system provides a self-protection mechanism by automatically disconnecting the motor during severe fault conditions, preventing permanent damage.

Abstract: Women’s safety has become a significant social and technological concern, particularly in remote and rural regions where immediate communication during emergencies is often unreliable due to poor network connectivity. Most existing safety solutions depend on cellular networks, which may fail in such environments, creating a critical need for an alternative approach. This project proposes ResQHer, a smart women’s safety device that employs LoRa-based hybrid communication to ensure long-range, low-power, and reliable transmission of distress alerts even in areas with limited or no internet access. The system integrates an ESP32 microcontroller, a LoRa SX1278 module for long-distance communication, GPS for real-time location tracking, and GSM/Wi-Fi as backup channels. When the emergency trigger is activated, the device instantly sends alert messages along with precise location details to predefined contacts and a centralized monitoring gateway. Designed to be compact, wearable, and energy-efficient, the device is suitable for everyday use and supports future enhancements such as continuous tracking, data logging, and integration with emergency response services. Overall, ResQHer aims to improve women’s personal safety by enabling faster assistance, dependable communication, and enhanced situational awareness across both urban and rural environments.

Abstract: Reliable navigation in environments where Global Positioning System (GPS) signals are unavailable or degraded remains a critical challenge for autonomous systems, defense operations, and underground or indoor applications. This research proposes a robust navigation framework that leverages Doppler-based velocity estimation to enhance positioning accuracy in GPS-denied environments. The system integrates inertial measurement units (IMUs) with Doppler shift observations derived from radio frequency or acoustic signals to provide continuous and drift-reduced localization. A sensor fusion approach, combining Extended Kalman Filtering and machine learning-based error correction, is employed to mitigate accumulated drift and measurement noise. The proposed model is evaluated in complex scenarios such as urban canyons, tunnels, and indoor settings, demonstrating improved trajectory estimation and resilience compared to conventional inertial-only methods. Experimental results indicate that Doppler-assisted navigation significantly enhances reliability, reduces positional error, and ensures continuous operation in challenging conditions. This approach offers a scalable and efficient solution for next-generation navigation systems in autonomous vehicles and robotics.

Abstract: The primary objective of this proposed research is to develop a new deep learning algorithm that can analyze neuroimaging data for early detection and diagnosis of brain diseases such as epilepsy, Parkinson's disease, Alzheimer's disease, and brain tumors. The algorithm will be developed using a combination of supervised and unsupervised learning techniques. The dataset will include a large number of neuroimaging scans, including MRI, CT, and PET scans, from patients with different brain diseases as well as healthy controls. The algorithm will be trained to differentiate between healthy and diseased brain scans and to classify different types of brain diseases based on the patterns observed in the neuroimaging data. The proposed algorithm will incorporate advanced deep learning techniques such as convolutional neural networks (CNNs), recurrent neural networks (RNNs), and autoencoders, which are specifically designed for processing large and complex datasets. The algorithm will also use transfer learning, which involves transferring knowledge learned from one task to another, to enhance the accuracy of the classification model. The proposed algorithm will be able to detect subtle changes in brain structure and function that may not be visible to the naked eye, enabling earlier detection and diagnosis of brain diseases. The proposed algorithm has the potential to significantly improve the accuracy and speed of diagnosis of brain diseases, leading to earlier and more effective treatment. It could also help identify new biomarkers for brain diseases, leading to a better understanding of the underlying mechanisms and potential new targets for therapy. Ultimately, the proposed algorithm could improve the quality of life for millions of people around the world who suffer from brain diseases such as epilepsy, Parkinson's disease, Alzheimer's disease, and brain tumors.
