    Sustainable Eco-friendly Reward Bin Using RVM by Detecting Recyclable waste and Generating points according to the weight of the Materials.
    (North South University, 2019-09-30) Md. Rubaith Adnan; Mehedy Hassan; Md. Anowar Hosen; Mohammad Bin Khesru; Zunayeed Bin Zahir; 1510538642; 1521214042; 1512366043; 1321489042
    In this project we present a system where the machine will receive three types of industrialized bottles and according to their weight it will generate some point for the user. With certain amount of points the user can collect money or some sort of reward depends on the system manufactures and the system service providers. First of all we will build a RVM (Reverse Vending Machine) and it can take three types of industrialized bottles like plastic bottles, Aluminum cans or Glass jars then it will measure the weight and pass to the next phase to sort it out. In the next phase the sensors will differentiate among these materials and will sort it and put them on desired container. While sorting the materials it already generated some points according to it’s weight. As we already set the threshold weight for the different materials the point Generation will be valid. The user will get a slip with point mentioned on it and s/he can collect The reward using that slip. The service provider will decide what type of reward a user will get At what amount of points. This project idea was developed because of the excessive amount of Plastic bottles on the street and it is harmful for the environment also. The recycling industries Are very profitable but it needs lots of manpower and it is not cost effective, so with this Machine it will be cost efficient as well as environment friendly. The people will encourage to Use the machine as they are benefiting. Thus this project is profitable from economic aspect at the same time it is very useful for keeping the environment from pollution which can not be reversed these days. We can see people using trash here and there even the vast ocean is getting polluted with this types of material everyday. No government or organization can do anything on their own in this regard but making people interested to keep the environment clean can be the next step to save the environment from destroying completely.

    Reconstructing Better Audio by Using Spetial Microphone
    (North South University, 2019-08-31) Md Mantasarul Elahi; Dr. Mohammad Ashrafuzzaman Khan; 1512518042
    This article describes the design and implementation of a program that is capable of taking audio from multiple sources and using two filters, it will create the best possible version of the audio that is possible. Firstly, after taking in audio from multiple audio recording sources, it will firstly go through ’Unwanted Noise Reduction Filter’ and its product will be a noise reduced output. After going through the first filter, the audio files will be filtered once again using ‘Voice Enhancement Filter’ and will produce an enhanced output. Lastly, all the audio files will be combined using ‘Audio Merging Process’ to produce the final output of the best possible version of the audio that has been recorded

    3D Multiplayer First Person Shooter Game
    (North South University, 2019-08-31) Samira Mahmood; Maruf Ahmed; Nafisa Mahbub Piyal; Md. Hayder Ali; AKM Bahalul Haque; 1520265042; 152 0054 042; 152 1230 642; 152 1231 642
    Video Games have always been a leading form of entertainment being available for people of all ages. Eventually, with the evolution of technologies improving the functionality of playing video games, multiplayer games have received increased popularity. In a multiplayer game, several people interact in real-time over a network like internet or a local connection. One of the primary reasons for multiplayer games receiving so much enthusiasm and attention is because of the thrilling experience of competing with human counterparts. Over the years, Bangladesh has become a significant part of the gaming community, yet there aren‘t many startups or individuals who are seeking to get involved in the lucrative game industry. In reference to the aforementioned facts and enormous popularity of multiplayer games, our incentive is to contribute and to be part of the global game industry. We plan to create a 3D multiplayer FPS (First Person Shooter) game with appealing graphics and visuals, and we‘ll also include some features to make the game stand out

    Face Recognition LogIn System
    (North South University, 2022) Md. Ibrahim Khalil Ullah; Md. Mehraj Uddin; Oali Ullah; Md. Abu Obaidah; 1812015042; 1813213643; 1612545042
    We can identify human faces using a web camera which is known as Face Detection. This is a very effective technique in computer technology. There are used different types of attendance systems such as log in with the password, punch card, fingerprint, etc. With rapid growth in the application of AI, Access Control Systems are walking in a new technology lane. Powered by deep learning technologies or cognitive analytics, login pages can implement more secure, efficient, and easy to use authentication systems. In this project, we have introduced a Facial Recognition type LogIn System that can identify a specific face by analyzing and comparing patterns of a digital image. This system is the Tensorflow LogIn System based on face detection. Primarily, the device captures the face images and stores the captured images into the specific path of the computer relating the information into a database. When anybody tries to enter into any website through this LogIn System, the system captures the image of that particular person and matches the image with the stored image. If this image matches with the stored image then the system allows the person to enter the website, otherwise the system denies entry.

    Enhanced Third Harmonic Generation (THG) with Graphite Metasurface
    (North South University, 2023) Ybtida Cinderella; Nasim Md Arafat Saikat; Mahdy Rahman Chowdhury; 1921957043; 1911471643
    This project introduces an innovative concept for improving third harmonic generation (THG) at far infrared and terahertz (THz) frequencies by employing ultrathin nonlinear meta surface designs of patterned graphite micro-ribbons. By utilizing the localized plasmonic effects, these configurations make it possible to produce an incident wave that is tightly confined and significantly amplified along the surface of the graphite. Because of the presence of a metallic substrate beneath the graphite micro ribbons, the resonant response bandwidth is reduced, which leads to the absence of any transmission and the development of standing waves within the intermediate dielectric spacer layer. This strategy results in a significant increase in the efficiency with which THGs are converted, one that could be increased by several orders of magnitude. Additionally, the meta surface's resonant frequency can be dynamically modified by changing the Fermi energy of the graphite through either electrical or chemical doping. This can be done to get the desired effect. The stimulation of highly localized plasmons within graphite micro-ribbons are the primary topic of this paper. This stimulation ultimately results in the confinement and intensification of the incident wave along the graphite surface. In addition, the presence of a metallic substrate beneath the graphite micro ribbons results in the induction of zero transmission and the generation of standing waves within the intermediate dielectric spacer layer, which together have the effect of narrowing the bandwidth of the resonant response. In the end, these improvements in the incident field contribute greatly to the gain in the efficiency with which THGs are converted.
