Abstract: Traffic Sign Recognition (TSR) is a critical component of autonomous driving systems and Advanced Driver Assistance Systems (ADAS). However, real-world environmental challenges such as occlusions, lighting variations, multi-scale changes, and motion blur often degrade the performance of traditional vision pipelines. This paper presents a robust real-time TSR system based on the YOLOv7 architecture. The proposed model leverages an E-ELAN backbone for hierarchical feature extraction, a PANet neck for multi-scale semantic fusion, and an anchor-free IDetect head for precise localization. Trained on a custom traffic_sign_data dataset with aggressive data augmentation, the system achieves 94% mAP@0.5 and 38% mAP@0.5:0.95 at 45 frames per second on an NVIDIA RTX 3090 GPU. Comparative evaluations show that YOLOv7 significantly outperforms YOLOv5 with 89% mAP@0.5 and Faster R-CNN with 91% mAP@0.5 at only 12 FPS. The model is further optimized via ONNX-to-TensorRT conversion, enabling efficient deployment on edge computing platforms such as NVIDIA Jetson AGX Xavier.

Abstract: This project provides a hybrid solution for the automated generation of timetables through the combination of Linear Programming (LP) and Constraint Satisfaction Problem (CSP) solutions. It’s intended to address the NP-hard problem of university course timetabling, which involves the satisfaction of a considerable number of conflicting constraints and preferences. The method for solving this problem involves two distinct steps. In the first step, a linear programming method is employed to determine the optimal assignment of teachers to subjects. This is a global optimisation technique that aims to maximize the satisfaction of teacher preferences and ensure a well-balanced allocation of teaching loads for all faculty members. In the second phase, a CSP algorithm with backtracking is applied to these optimal assignments to further assign time slots and classrooms. This phase is handled by both hard and soft constraints. Hard constraints, such as the unavailability of a teacher or a classroom, are represented by hard constraints that should not be violated to avoid any scheduling conflicts. Soft constraints, such as teacher time slot preferences and constraints on the lecture interval, are employed to filter the most optimal assignments from the pool of feasible solutions to enhance the quality of the schedule.

Abstract: The campus environment in universities includes many blocks laboratories offices hostels libraries and other facilities spread across different areas which makes navigation difficult for students visitors and staff. The existing methods such as signboards printed maps and verbal directions do not provide proper support and users often struggle to find the correct location. The absence of real time guidance creates confusion especially during busy periods like admissions examinations and events where many people move at the same time. The difficulty increases when users are not familiar with the campus layout and this leads to time loss and frustration. The need for a simple reliable and easily accessible navigation system becomes very important in such situations. The proposed system is an AR based smart campus navigation solution that works through a mobile browser without the need for any application installation. The system uses GPS and device sensors to continuously track user position and direction and provides accurate navigation support. The A star algorithm is used to calculate the shortest path between the current location and the destination and this improves navigation efficiency. The guidance is shown using augmented reality arrows on the camera view which makes directions easy to understand and follow. The system also includes an AI chatbot for user queries voice guidance for hands free navigation and crowd prediction to avoid busy areas. The Firebase database is used to provide real time information such as lab availability staff details and event updates. The system provides a complete and user friendly solution for campus navigation.

Abstract: In order to build solid relationships between colleges, their alumni, and present students, alumni en- gagement is essential. A specialized platform called ALUMNI CONNECT: BRIDGING THE GENERATION was created to strengthen these connections by offering a controlled, engaging envi- ronment for networking, career development, and mentoring. Key elements of the platform include job advertising, mentorship programs, discussion boards, guidance requests, regional alumni filters, alumni contributions, including donations, lab installations, and event planning. Furthermore, it maintains a trustworthy community by removing phony accounts and verifying profiles to guarantee authentic- ity. The initiative’s main driving forces are the underutilization of alumni networks and the dearth of easily accessible, individualized student counseling. By tackling these issues, the platform encour- ages deep connections, allowing alumni to commemorate successes and offer insightful career guidance and university-specific recommendations. Students can close the gap between academic accomplish- ment and career success by gaining access to industry connections and mentorship possibilities through increased engagement. In order to improve professional development and institutional linkages,this project seeks to establish a smooth and effective alumni-student engagement paradigm. ALUMNI CONNECT hopes to create a thriving self-sustaining ecosystem that benefits both students and alumni by utilizing technology to promote involvement.

Abstract: The scope of enterprise reporting systems has grown significantly as far as data size, dashboard interactiveness, and visual analytics are concerned. However, in most companies, these systems operate as a static support for making decisions instead of an active decision system. The issue is that even though the dashboards detect patterns, anomalies, and trends, the user should understand these results and trigger the next steps. This implies some time lag, inconsistencies, and dependency on human decision-making. Thus, in this article, we propose a mixed AI-agent framework of enterprise decision systems where the intelligence ability of artificial intelligence is complemented by the execution capabilities of intelligent agents through staged development. The framework involves data collecting, cleaning, transformation, creation of dashboards, analysis with the help of machine learning algorithms for predictions, classifications, clustering, and detecting anomalies, and finally, the use of agents that translate model outputs into workflow activities such as approval, escalating, prioritizing, and notifying. The primary idea of this research is to split the process of intelligence generation and actions taking at different process stages, thereby increasing the modularity, interpretability, and effectiveness. However, it retains its practical applicability and relevance of dashboard analysis. The paper discusses the conceptual framework, technical design, model types, logic of process mapping, criteria of assessment, governance issues, and the possibility of enterprise implementation of the proposed approach

Abstract: Artificial Intelligence based conversational systems are transforming how information services are delivered in many fields including education. Students frequently require quick access to academic information such as course details, admission procedures, faculty information, and examination schedules. However, traditional communication channels such as notice boards, websites, and help desks often fail to provide instant responses. This research proposes ChatGMVIT, an AI-powered chatbot designed to assist students by providing instant responses to institutional queries. The system is implemented as an Android application integrated with Firebase Firestore as a knowledge database and the Gemini 2.5 Flash Lite model for natural language processing.

Abstract: Forecasting financial market trends has become an important task for investors, financial institutions, and analysts due to the increasing complexity and volatility of modern financial systems. Accurate prediction of market movements such as stock prices, exchange rates, and commodity prices can significantly assist in making informed investment decisions and managing financial risks. However, financial market data is highly dynamic, nonlinear, and influenced by multiple economic and external factors, which makes accurate forecasting a challenging problem for traditional statistical methods. In this study, a machine learning-based framework is proposed for forecasting financial market trends using time series analysis. The proposed approach utilizes historical financial data including stock prices, trading volumes, and other relevant financial indicators to train predictive models capable of identifying patterns and relationships within the data. A Support Vector Machine (SVM) algorithm is employed as the primary forecasting model due to its strong capability to handle nonlinear relationships and high-dimensional datasets effectively. The system performs several important stages including data loading, preprocessing, feature selection, model training, and performance evaluation. During preprocessing, missing values and irregularities in the dataset are handled, and normalization techniques are applied to ensure consistent feature scales. The processed data is then used to train the SVM model, which learns complex patterns present in historical financial data to generate predictions for future market trends. The performance of the forecasting model is evaluated using standard evaluation metrics such as Mean Squared Error (MSE) and Mean Absolute Error (MAE) to measure prediction accuracy. Experimental analysis demonstrates that the proposed machine learning framework is capable of effectively capturing nonlinear patterns present in financial time series data and providing reliable forecasting results. By leveraging machine learning techniques, the proposed system improves prediction efficiency and supports intelligent decision-making for traders, investors, and financial analysts. The framework can serve as a valuable tool for financial market analysis and can be further enhanced by integrating hybrid machine learning models and real-time financial data sources.

Abstract: Hearing impairment is one of the most common sensory disorders affecting newborns, infants, and young children worldwide. Early detection of hearing loss is crucial because delayed diagnosis can negatively affect speech development, cognitive growth, social interaction, and educational outcomes in children. However, many developing and underdeveloped regions face a shortage of audiologists and otolaryngologists, which often results in delayed diagnosis and limited access to hearing care services. This situation highlights the need for automated and intelligent diagnostic tools that can assist healthcare professionals in identifying hearing impairments more efficiently. This study proposes an automated hearing loss detection framework based on machine learning techniques to support medical professionals in diagnosing hearing impairments in newborns, infants, and toddlers. The proposed system integrates a hearing test data generation module with a machine learning classification model capable of analyzing audiometry test data and predicting the presence and characteristics of hearing loss. The data generation module creates a comprehensive dataset representing different hearing conditions, which is then used to train and evaluate the machine learning model. By employing multiclass and multi-label classification techniques, the model can identify the type, degree, and configuration of hearing loss with high accuracy. Experimental results demonstrate strong diagnostic performance, achieving a prediction time of approximately 634 milliseconds, a log-loss reduction rate of 98.48%, and macro and micro precision values close to 100%. These results indicate that the proposed framework can provide rapid and reliable diagnostic support for healthcare professionals, enabling earlier intervention and improving access to hearing care in regions with limited medical resources.

Abstract: With the rapid expansion of Android applications, malware attacks targeting mobile devices have increased significantly, creating serious security and privacy concerns for users. Traditional malware detection approaches, such as signature-based and rule-based methods, often fail to detect newly emerging or obfuscated malware variants. To overcome these challenges, this study proposes an explainable artificial intelligence-based framework, named XAI-Droid, for effective Android malware detection and classification. The proposed system integrates deep learning techniques with explainable AI (XAI) methods to enhance detection accuracy while ensuring transparency and interpretability in decision-making. Feature extraction is carried out using static analysis techniques, and the extracted features are used to train advanced machine learning and deep learning models. To improve trust and reliability, explanation methods such as feature importance analysis are incorporated to identify the key attributes influencing classification outcomes. Experimental results demonstrate that the proposed framework achieves high detection accuracy while maintaining interpretability, making it suitable for practical cybersecurity applications. By combining strong classification performance with explainability, XAI-Droid contributes to the development of reliable and trustworthy AI-based mobile security systems.

Abstract: To improve prediction accuracy and enable real-time monitoring of mechanical components, a deep learning-based approach is proposed. The system utilizes a Convolutional Neural Network (CNN) to extract important features from mechanical parts using sensor data. These features are further processed through fully connected layers for information fusion and classification, allowing accurate prediction of remaining useful life and health status. The trained deep learning model is integrated into a monitoring system to create a complete framework for continuous condition monitoring and life prediction. The system is further optimized to enhance prediction accuracy, real-time performance, and adaptability under different working and environmental conditions. Experimental results show that the proposed model achieves high performance with a Mean Absolute Error (MAE) of 2.1, Root Mean Squared Error (RMSE) of 2.5, and Mean Absolute Percentage Error (MAPE) of 10%. These results demonstrate the effectiveness of the approach and its potential for practical applications in industrial maintenance and reliability improvement.
