Augmented reality is a technology that combines virtual things with the actual environment and allows them to interact with one another. Although augmented reality applications are employed in a variety of fields, education is by far the most essential. AR technology combines real things with virtual information to boost students' connection with physical environments while also facilitating their learning. Virtual reality gadgets, which are still under development, allow students to learn hard topics in a fun and easy method. Students can learn more about the virtual environment by interacting with objects in it. Lessons can be taught in the company of a teacher as if they were present at the time by scheduling digital tours to a museum or zoo in a completely different nation. In light of all of this, this research is a compilation. In this context, augmented reality technologies were introduced, and examples of their application in many disciplines of education were given. The prepared sections should be carefully studied by the educators and put into practise in their courses, according to a suggestion made at the conclusion of the study. Furthermore, it was stated that it should be preferred in order to successfully engage with pupils by interacting in real time.

Voting is a means to strengthen the democratic processes in modern world. E-voting is a new voting mechanism in information world. It is important that this system is in compliance with legal framework. E-voting must technically meet user requirements and more importantly security requirements. This paper aims to identify the basic legal requirements, which should be met while designing an e-voting system. This will establish faith in legal acceptance of e-voting system by 1ensuring that its secure. These requirements come from original way of voting using ballet box. The paper concludes that an e-voting capability should be considered dependable and can be used to replace traditional election processes as long as it operates under the established and secure framework. This is important in developing countries as elections happen at various levels all the time and this ensures fair, speedy and low cost election. These can however also be used to complement the traditional process, if masses find it difficult to replace it as there is digital divide, related to inherent distrust in the e-voting procedure. And at certain places there may be inadequate arrangements to meet certain requirements.

Obstacle detection for vehicles is important for the safety of human life. If there is any obstacle in the road it may cause accidents as well as this affects the traffic flow of vehicles. To prevent such accidents, it is important to detect the obstacles in real-time. But it is difficult to analyze due to factors related to shadow or sudden changes in the environment and obstacles ahead of the vehicle. Fog is one of the important factor that can cause vehicles not to identify the nearby objects. This paper aims to design a new approach for obstacle detection which is based on moving objects. This approach is more useful for identifying the minute obstacles in which becomes invisible due to fog, so assistance to the driver is provided and this ensures more safety. The main focus of this project is to find the find the distance, the driver can see nearer vehicle or obstacle and under each type of fog the maximum distance of visibility. The visibility distance measurement between two vehicles and an obstacle to vehicle distance measurement can be calculated using visual aids.

An antenna is a device that can send and receive signals for radio propagation. The development of fast and fixed portable communication systems requires a high level of transition to a wider area due to the increase in network users. This can be done using multiple bands. To strengthen the characteristics and performance of the antenna, microstrip antenna design techniques, various structures and shapes, analysis and feeding methods are applied. Therefore, to achieve multi-band operation in a limited space, the antenna is designed in an E-shape in combination of various shape slot to achieve multi-band operation. Simulation results show that the proposed antenna operates at two different frequencies, 3.57 GHz, and 5.73 GHz, and can be used in various wireless applications such as Wi-Fi and mobile Wi-MAX. All simulation results such as resonant frequency, return loss, radiation pattern and measurement results of the simulated antenna are presented in this paper. HFSS software has been used for simulation and analysis work.
