    Get PDF
    Plant leaf diseases pose a danger to food security, and their rapid identification is made more difficult in many areas by a lack of infrastructure. This thesis is a concentrated attempt to address this important problem by utilizing state-of-the-art deep learning techniques, with a focus on the YOLOv5 model, to offer a dependable and effective solution for plant leaf disease detection in agriculture. The introduction emphasizes the serious effects that plant diseases have on a global and financial level, underscoring the critical necessity for early detection to lessen these effects. Driven by the promise of technology to revolutionize agriculture, this work carefully investigates the complex use of deep learning techniques. YOLOv5 is trained to demonstrate its ability to distinguish between healthy and diseased plant leaves using a carefully chosen tomato dataset. The dataset contains nine different types of illnesses. The model achieves an impressive 92.6 percent average precision, indicating a high degree of disease detection accuracy. Plant leaf disease detection in agriculture faces many complicated obstacles, and the successful deployment of the trained model through the Flask framework represents a significant leap in the practical application of deep learning to address these issues. Our multimodal approach places our research at the forefront of efforts to improve agricultural technology and guarantee global food security while also making a significant contribution to the scientific understanding of disease identification and laying the foundation for future advances

    To speed the rate of higher education government (govt.) has increased and promoted the number of govt. degree level institutions as higher level honor’s and master’s institution. There is no measure to ensure quality of these higher educational institutions as prescribed in the public universities or international universities. To know service quality and performance of the service provider groups measuring service quality is very much significant. For this purpose, we have to measure students’ expectations from the service entity and their perceptions about the actual services they get. The govt. colleges that provide higher education need to understand the customers’ (students’) perceptions of service quality and identify the gaps between their expectations and these perceptions. This part of the research studies students’ expectations and perceptions of service quality in the present educational environment by using the modified service quality (SERVQUAL) model given by Parasuraman et.al for distinctive nature of service. The modified SERVQUAL instrument will measure five dimensions i.e. tangibles (academic, non-academic), reliability, responsiveness, assurance and empathy. This study has been done over 382 undergraduate and post graduate students of selected four govt. colleges from top ten ranking 2016 by National University of northern division Rajshahi and Rongpur. Next the descriptive statistical analysis with mean scores, standard deviation and crosstabs in different perspective by colleges and respondents with service dimensions. Service quality has been measured by subtracting students’ expectations mean scores from their perceptions mean scores of different service items related to educational services based on SERVQUAL dimensions. A structured questionnaire has been supplied with same type questions to know students’ expectations and perceptions with a 5 point Likert type scale. The study found that all the SERVQUAL components has made negative scores of service quality of higher education in govt. colleges

    The Traditional attendance management systems, which rely on human operations or RFID-based solutions, frequently struggle with scalability, accuracy, and efficiency. This thesis proposes an Automated Attendance Management System (AAMS) that employs a customized YOLOv9-C model for real-time facial recognition via deep learning. The model's performance is significantly improved by adding Squeeze-and-Excitation (SE) blocks and the Complete Intersection over Union (CIoU) loss function. On a custom dataset, the baseline YOLOv9-C model had 86.2% precision and 84.9% recall, with a mean Average Precision (mAP) of 89.9% at IoU threshold of 0.5. However, the revised YOLOv9-C(M) model demonstrated significant gains, including a mAP of 93.8%, as well as improved precision (94.1%) and recall (96.6%). These improvements can be due to the introduction of SE blocks, which promote feature recalibration, and the CIoU loss function, which maximizes bounding box localization and increases detection accuracy even in tough conditions such as occlusion or dimly lit areas. The improved YOLOv9-C model consistently outperforms the existing YOLO models (YOLOv5, YOLOv7, and YOLOv8s), according to a comparison study. The mAP for YOLOv5 was 80.2%, YOLOv7 was 89.1%, and YOLOv8s was 91.4%. In contrast, the upgraded YOLOv9-C model outperformed the others, with greater robustness, precision, and recall. The system employs a one kind of custom dataset to evaluate the model's performance in some scenarios and settings, as well as to ensure trustworthy workforce detection in diverse contexts. By automating the attendance process, this technology reduces errors, saves administrative time, and promotes institutional efficiency
