    The Advance Virtual Classroom and Automated Grading System, which aims to revolutionise the traditional education system by integrating virtual classroom functionalities and automated grading, highlights the need for flexible and accessible learning platforms that can enhance student engagement and streamline the grading process. The current status of the system indicates its final stages. It mentions that the system has been designed and implemented with the goal of providing a comprehensive virtual classroom experience and automating the grading process to improve efficiency and accuracy. The methods followed in the development of the system mention the utilisation of advanced technologies, such as web development frameworks and machine learning algorithms, to create a user-friendly virtual classroom environment and implement automated grading mechanisms. The abstract also highlights the integration of secure examination systems to ensure the integrity of assessments. The results acquired through the implementation of the Advance Virtual Classroom and Automated Grading System It states that the system has successfully provided students with a virtual classroom experience that includes features such as live video lectures, interactive discussions, and collaborative tools. Additionally, the system's automated grading component has demonstrated improved accuracy and efficiency in evaluating student assessments. The impact and significance of the results obtained from the system It highlights the potential of the Advance Virtual Classroom and Automated Grading System to revolutionise education by enabling flexible and accessible learning, enhancing studentteacher interaction, and reducing the administrative burden of manual grading. The system's implementation can lead to improved learning outcomes, increased efficiency in grading, and a more engaging educational experience for both students and instructors.

    An economic and automatic water quality monitoring system in the light of industry 4.0

    Water quality monitoring is significant for sustainable aquaculture. It helps to reduce the risk of unwanted fish loss due to poor water quality, as a result, farmers can maximize profit. DO, Ammonia, pH, Temperature, Turbidity and TDS are the key parameters and their correct level in water ensures favourable conditions for aquaculture. However, in the aquaculture industry, DO and ammonia measurement with digital systems are costly. Eventually, it is inevitable for the aquaculture farmers to measure the other parameters (pH, Temperature, Turbidity and TDS) by the side of DO, Ammonia. Therefore, we have developed a system in the light of industry 4.0 with the aid of IoT that can monitor automatically the above-mentioned water quality parameters without human involvement and keep the users updated remotely with the help of an android app. The system is expected to achieve more than 98% accuracy in DO tests and nearly 99+% accuracy in ammonia measurement in water. Other parameter readings like temperature, turbidity, and PH have produced a high precision result as modern sensors are used. Our study shows that the developed system can cut down the overall cost (accusation and test) by approximately 85% and it will open a new door of opportunity for aquaculture automation. DO, Ammonia, PH, Temperature, Turbidity and TDS

    The world is using up all the resources to meet the daily demands of energy and it is quite expectable that in the near future we will run out of any naturally occurring ore/mineral/petroleum. As a result, renewable energy solution has achieved a great The world is using up all the resources to meet the daily demands of energy and it is quite expectable that in the near future we will run out of any naturally occurring ore/mineral/petroleum. Demand today to save the natural resources and also to tackle the crisis of energy. Solar energy is rapidly gaining its popularity as an important source of renewable energy. But the efficiency of solar panel is a big factor. While the sun keeps following a parabolic path throughout the day, the panels which are used in our country are generally fixed to a pole or the roof of the house and hence, throughout the day, the efficiency decreases significantly. In this thesis, we have constructed a 2 axis solar tracker which can track the sun throughout the day to obtain the maximum efficiency. This project discuss the design and construction of a prototype for solar tracking system that has a single axis of freedom. Light Dependent Resistors (LDRs) are used for sunlight detection.
