FUTURE PROJECTS
Integration of Advanced Technologies for Energy Storage Systems
The transition to renewable energy is a global priority as we seek to mitigate climate change and reduce dependency on fossil fuels. Solar and wind energy, two of the most widely adopted renewable sources, present unique challenges due to their intermittent and variable nature. Energy storage systems are critical in addressing these challenges, ensuring a stable and reliable power supply. However, conventional energy storage systems struggle to efficiently manage the rapid fluctuations inherent in renewable energy generation. This proposal seeks to develop a Hybrid Energy Storage System (HESS) that integrates supercapacitors, lithium-ion batteries, and multi-level inverters. The aim is to enhance the overall performance, efficiency, and reliability of hybrid solar-wind energy systems by leveraging the strengths of each component: supercapacitors for rapid response to power fluctuations, batteries for long-term energy storage, and multi-level inverters for high power quality.

Smart Guard: Advanced Wearable Health Monitoring and Alert System
The "Smart Guard: Advanced Wearable Health Monitoring and Emergency Alert System" is designed to enhance personal health monitoring through an integrated wearable device that tracks critical health metrics, including heart rate, body temperature, blood oxygen levels, diabetes management, stress level, GPS location, electrical activity of the heart (ECG), and it also detects when a person falls due to any health issue. This system aims to provide real-time monitoring and emergency alerts, making it particularly valuable for individuals with chronic health conditions, elderly people and athletes. The wearable device utilizes advanced sensors and microcontrollers to continuously gather and analyze data, which is then transmitted to a mobile application for real-time tracking and alerting. In case of an abnormal health event, such as a fall or a significant deviation in vital signs, the system automatically sends an alert to pre-configured emergency contacts with the wearer’s GPS location.

Colonoscopy is an important diagnostic tool in the field of medicine, allowing for a thorough examination of the colon's interior and the critical detection of abnormalities. The quality of the images acquired during a colonoscopy procedure is critical in the diagnostic process, influencing lesion detection, precise localization of abnormalities, and overall diagnostic confidence. In this comprehensive investigation, we delve into the numerous factors that have a significant impact on image quality in colonoscopy. These factors, which include resolution, contrast, colour representation, sharpness and clarity, and noise, are fundamental to medical practice and patient care. The main aim of this work is to improve the image quality specifically by the application of resolution enhancement technique. The quality of the resulting image depends on the chosen scaling factor and the types of interpolation methods namely Nearest Neighbour, Bilinear, Lanczos windowed sinc and bicubic interpolation adopted during the process. The results obtained from this work demonstrate that adapting the scaling factor of 2 and the Lancozs interpolation method provides the image with better quality when compared to the original image with PSNR and SSIM values of 35.5 and 0.92 respectively. The quality of the image is evaluated by using the metrics Peak-Signal-to-Noise -ratio (PSNR) and Structural Similarity Index (SSIM). Higher PSNR and SSIM values are often required to ensure diagnostic accuracy which aids in the early detection of abnormalities and precise localization, which can be life-saving in colorectal conditions.

This paper presents a design procedure for a Robust and Adaptive Fuzzy Logic based Power System Stabilizer (RAFLPSS) to improve the small signal stability of Power System. The parameters of RAFLPSS are tuned by adaptive neural network. This RAFLPSS uses ANFIS network (Adaptive Network based Fuzzy Inference System) which provides a natural framework of multi-layered feed forward adaptive network using fuzzy logic inference system. In this approach, the hybrid-learning algorithm tunes the fuzzy rules and the membership functions of the RAFLPSS. The dynamic performance of SMIB system with the proposed RAFLPSS under different operating conditions and change in system parameters has been investigated. The simulation results obtained from the conventional PSS (CPSS) and Fuzzy logic based PSS (FPSS) are compared with the proposed RAFLPSS. The simulation results demonstrate that the proposed RAFLPSS performs well in damping and quicker response when compared with the other two PSSs.

AbstractThis paper presents a design procedure for a robust and adaptive fuzzy neural network‐based power system stabilizer (RAFNNPSS) and investigates the robustness and adaptive feature of the RAFNNPSS for a single machine connected to an infinite bus system and multi‐machine power systems in order to enhance the dynamic stability (small signal stability of the system). The parameters of RAFNNPSS are tuned by adaptive neural network (NN). This RAFNNPSS uses adaptive network‐based fuzzy inference system (ANFIS) network, which provides a natural framework of multi‐layered feed forward adaptive network using fuzzy logic inference system. In this approach, the hybrid‐learning algorithm tunes the fuzzy rules and the membership functions of the RAFNNPSS. Speed deviation of synchronous generator and its derivative are chosen as the input signals to the RAFNNPSS. The dynamic performance of single‐machine infinite bus (SMIB) system, a two‐area, five‐machine, eight‐bus power system and a large power system (10‐machine, 39‐bus New England system) with the proposed RAFNNPSS under different operating conditions and change in system parameters have been investigated. The simulation results obtained from the conventional PSS (CPSS) and Fuzzy logic‐based PSS (FPSS) are compared with the proposed RAFNNPSS. The simulation results demonstrate that the proposed RAFNNPSS performs well in damping and quicker response when compared with the other two PSSs. Copyright © 2008 John Wiley & Sons, Ltd.

Optimal tuning of power system stabilizer (PSS) parameters using genetic algorithm with single objective function is presented in this paper. A Single Machine Infinite Bus (SMIB) system is considered. The main objective of this research paper is to investigate the suitability of genetic algorithm for effective tuning of parameters of the power system stabilizer in a single machine infinite bus system. A conventional speed based lead‐lag PSS is used. A simple and effective method of tuning the parameters of PSS is proposed which is posed as an optimization formulation by maximizing the damping of modes of oscillations of the SMIB system over a wide range of loading conditions and different system configurations. It is found that GA based PSS with single objective design shows improved dynamic performance over Conventional PSS over a wide range of operating conditions and different system parameters.
