Abstract: The growing demand for eco-friendly and high-efficiency solar energy technologies has driven the exploration of lead-free perovskite materials as viable alternatives to traditional lead-based compounds. This project investigates the photovoltaic performance of a novel lead-free chalcogenide perovskite, BaHfS₃, under pressure-tuned conditions (0 GPa and 25 GPa) using SCAPS-1D simulation software. At 25 GPa, BaHfS₃ exhibits a direct bandgap of 1.30 eV — nearly ideal for single-junction photovoltaic applications under the Shockley–Queisser limit. A total of 64 device configurations were tested by varying Electron Transport Layer (ETL) and Hole Transport Layer (HTL) materials. The optimal structure identified was FTO/CdS/BaHfS₃/NiO/Au, achieving a power conversion efficiency (PCE) of 28.71% with a Voc of 0.9591 V, Jsc of 34.42 mA/cm², and FF of 86.98%. Key parameters including absorber layer thickness, doping concentration, defect density, and series/shunt resistance were systematically optimized. The study confirms BaHfS₃ as a sustainable and efficient absorber layer with significant potential for next-generation non-toxic and stable photovoltaic technologies.

Abstract: The way networks work is changing fast, and that means we are more open to Cybersecurity threats. Old security systems do not work well together. They do not give us a clear picture of what is happening right now. This paper is about the design and implementation of a Real- Time Threat Detection Dashboard. This dashboard uses open-source tools to keep an eye on network threats all the time, analyze them, and show them in a way that is easy to understand. The system uses Suricata to detect intrusions, Nmap to find assets, and a web-based dashboard built using Flask and React. This framework lets us process security events in time and gives us useful information through visual analytics. We tested the system in a controlled environment. It worked well, detecting and showing threats with very little delay.

Abstract: Flooding is one of the most severe natural hazards, leading to significant losses in human life, infrastructure, and economic resources, particularly in flood-prone regions such as India. Rapid and reliable identification of inundated areas is essential for effective disaster response, mitigation planning, and resource allocation. Conventional flood mapping techniques are often labor-intensive, time-consuming, and limited by environmental constraints. In particular, optical satellite imagery is highly affected by cloud cover and poor visibility during extreme weather conditions. To address these limitations, this study proposes an automated flood assessment framework utilizing satellite-based remote sensing data. The approach primarily leverages Synthetic Aperture Radar (SAR) imagery, which enables consistent data acquisition irrespective of weather conditions or illumination. The proposed framework integrates image preprocessing, change detection, and region extraction techniques to identify flood-affected areas by analyzing temporal variations between pre-event and post-event images. The system is designed to efficiently highlight newly formed water bodies and quantify flood impact through statistical and visual outputs. A web-based interface is incorporated to enhance accessibility and interpretation of results. Experimental observations demonstrate that the proposed method provides reliable flood detection across diverse terrains, including urban and vegetation-covered regions. This work contributes toward developing a scalable and efficient solution for large-scale flood monitoring, supporting timely decision-making and improving disaster management strategies.

Abstract: A novel protection coordination approach utilizing artificial neural networks (ANNs) is introduced in this work for meshed high-voltage transmission systems. Existing overcurrent and distance relay coordination methods in meshed topologies are prone to relay blinding, zone overreach, and incorrect operation during power swing events. The developed ANN model is trained using an extensive fault scenario dataset generated through simulation of a 9-bus, 230 kV benchmark network in MATLAB/Simulink. The proposed architecture—with 18 inputs, three hidden layers containing 36, 24, and 12 neurons respectively, and a 9-output trip signal layer—delivers improved coordination speed, selectivity, and sensitivity over traditional relay configurations. Testing results demonstrate a fault classification accuracy of 98.54% on previously unseen data. On average, fault clearance times are shortened by 56.8% in comparison to conventional coordination approaches, and dependable detection of high-impedance faults is also achieved. The approach provides a flexible and adaptive protection solution well-suited to contemporary interconnected power grids.

Abstract: In today’s world, where we’re flooded with information, having a smart and efficient search system is more important than ever. Traditional search engines like Google rely on keywords and fixed ranking systems such as PageRank. While these methods work well, they often fail to truly understand what a user means, handle complex multi-step questions, or deliver deeply personalized results beyond just rewording queries. Recent advancements in AI, especially large language models (LLMs), have given rise to tools like Perplexity.ai and You.com, which combine search results into easy-to-read summaries. However, these tools still have limitations they lack deep personalization, emotional understanding, field-specific tuning, and adaptability to a user’s evolving search journey. This study presents a next-generation AI-powered search engine that bridges these gaps. It combines Google’s Custom Search API for scalability with advanced natural language processing for contextual understanding and intelligent recommendation systems. What sets this system apart is its ability to build a growing map of a user’s knowledge over time. It dynamically adapts to multi-step queries and continuously refines results to match the user’s needs and learning path. Our approach aims to connect the precision of keyword-based searches with the flexibility of conversational, chat-style searches. The result is more relevant answers, reduced search fatigue, and a smoother, more personalized experience especially valuable for academic research, technical exploration, and other knowledge-intensive tasks.

Abstract: Agriculture is an important sector in terms of food security and economic development, especially in developing nations. Precise crop yield estimation is required for efficient agricultural planning and management in the context of the increasing effects of climate change. Crop yield is affected by various factors, including climate variability, soil type, and availability of nutrients. Conventional crop yield estimation techniques, which rely on average values and traditional knowledge, are not reliable due to the complexities involved in crop yield estimation. Proposed in this paper is a framework for crop yield prediction using machine learning, incorporating climatic and soil variables. The climatic variables of rainfall, temperature, and humidity, and soil variables of soil pH and necessary nutrients (nitrogen, phosphorus, and potassium) are used as input variables. Three supervised machine learning algorithms—Linear Regression, Random Forest, and Gradient Boosting—are applied and compared to assess their predictive capability. Linear Regression is applied as a baseline algorithm, while ensemble methods are applied to deal with non-linearities in agricultural data. The performance of the models is measured using typical regression evaluation criteria, including Mean Absolute Error (MAE), Root Mean Square Error (RMSE), and R-squared (R²). The experimental outcomes show that the models based on ensemble methods perform better than the baseline model in terms of prediction accuracy and generalization ability. The results confirm that the combination of climatic and soil properties helps to improve crop yield prediction.

Abstract: This paper presents the design and practical implementation of a solar-driven, self-navigating vacuum robot intended for use in indoor settings. The system harnesses photovoltaic energy to eliminate grid dependency, uses a multi-sensor arrangement for real-time obstacle detection, and incorporates an Arduino Mega 2560 microcontroller for centralized decision-making. The prototype was subjected to rigorous testing across multiple indoor scenarios, where it recorded a 97% obstacle detection accuracy, approximately 94% cleaning coverage, and a continuous runtime of 60–70 minutes following a 3–4 hour solar charge. The outcomes confirm that merging renewable energy with embedded robotics yields a cost-effective and sustainable alternative to conventional cleaning appliances.

Abstract: The use of Generative AI has started changing how software is developed today. Many tools are now available that help developers write code faster or fix errors, but most of them only support specific tasks. They do not handle the complete software development process from In this paper, we propose a system called JellyfishAI ,which aims to automate the full software development lifecycle. The idea is simple — a user can describe their requirements in normal language, and the system will generate a complete, ready-to-use application. It combines different technologies like natural language processing, code generation models, testing, and deployment into one system. Technology is advancing very fast, and modern applications need to be scalable, reliable, and developed quickly. Because of this, traditional development methods are under a lot of pressure. Usually, software development includes many steps like requirement analysis, design, coding, testing, and deployment. These steps often require manual work and skilled developers, which makes the process slow and costly. It can also lead to mistakes and inconsistent results. With the introduction of Generative AI, things have started to improve. These systems can understand user input and generate code, documentation, and even design ideas. They help developers save time by assisting in coding and debugging tasks. However, these tools still have limitations. Most of them only focus on one part of development, like code suggestions or bug fixing, and do not provide a complete solution. Another issue is that developers still need to use multiple tools separately and connect them manually. This makes the workflow complicated and less efficient. Also, the code generated by AI tools often needs to be checked by humans to ensure it is correct, secure, and follows proper standards. Even though CI/CD pipelines help automate deployment, they mostly follow fixed rules and do not have intelligent decision-making capabilities. Similarly, testing tools can find errors but cannot automatically improve the quality of the code. Because of this, there is a need for a system that can intelligently manage all stages of development together. Today’s software systems are also becoming more complex, and there is a growing need to build applications quickly. Startups and companies want to turn their ideas into working products as fast as possible. However, depending on skilled developers and manual work often slows things down. This becomes even more difficult when dealing with large systems that require proper coordination and integration. To solve these problems, we introduce JellyfishAI, which is designed to automate the entire development process. Unlike existing tools, this system brings everything together in one place. It can understand user requirements, generate code, test it, check for errors, and deploy the application automatically. The system is built using multiple layers that include language processing, AI-based code generation, validation, and deployment. This ensures that the generated code is not only functional but also tested and ready to use. The system also improves over time using feedback and learning mechanisms. JellyfishAI also focuses on important factors like security, scalability, and maintainability. It includes features to detect vulnerabilities, manage dependencies, and improve performance, so that the final application meets industry standards. This system can change how software development is done. By automating repetitive tasks, developers can focus more on designing and solving problems instead of doing routine work. It also makes it possible for people without strong technical skills to build applications. In conclusion, AI has the potential to improve software development by making it faster, cheaper, and more efficient. However, to achieve full automation, we need systems that combine all stages of development in one place. JellyfishAI is an attempt to do that by providing a complete, end-to-end solution for building software automatically.
