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.

দেশের শিক্ষা ব্যবস্থা এক ধরনের আমলাতান্ত্রিক জালে আটকা আছে : বণিক বার্তা সাক্ষাৎকার -নর্থ সাউথ বিশ্ববিদ্যালয়ের (এনএসইউ) উপাচার্য অধ্যাপক আবদুল হান্নান চৌধুরী
(বণিক বার্তা, 2025-01-24) বণিক বার্তা
আমাদের শিক্ষা ব্যবস্থায় প্রাথমিক পর্যায় থেকে ওপরের স্তরে প্রতিটি ক্ষেত্রে ঘাটতি রয়ে যাচ্ছে। আমরা যদি তাদের দক্ষতা গড়ার দিকে মনোযোগ দিতাম, তাহলে কিন্তু তারা নিজেরা চাকরি খোঁজার চেয়ে অন্যের জন্য চাকরি সৃষ্টির দিকে মনোযোগী হতে পারত। আমাদের রাষ্ট্রকাঠামো শিক্ষাকে অনেকটা প্রশাসনিক বিধিনিষেধের মধ্যে রেখেছে। অথচ শিক্ষা বা উচ্চশিক্ষা তো আসলে মুক্ত হওয়া উচিত। বাংলাদেশকে এগোতে হলে উচ্চশিক্ষাকে স্বাধীনতা দিতে হবে। সেই স্বাধীনতা যদি না দিই, বাংলাদেশ কখনো এগোতে পারবে না। নর্থ সাউথ ইউনিভার্সিটি একটি অনন্য শিক্ষাপ্রতিষ্ঠান। আমরা সব সময় উদ্ভাবন, সৃজনশীলতাকে উৎসাহ দিই। উপাচার্য হিসেবে আমার চেষ্টা থাকবে—আরও বেশি আন্তর্জাতিকীকরণ। আমার চেষ্টা থাকবে, নর্থ সাউথ ইউনিভার্সিটিকে আরও বৈশ্বিক জায়গায় নিয়ে যাওয়া।

Trapping An Atom and Assessing The Difference in Trapping Force Using Two Different Systems
(North South University, 2023) Taiful Islam; Arnab Roy Biswas; Zahin Ibne Amir; Mahdy Rahman Chowdhury; 1912105042; 1921619043; 1822071043
This report demonstrates the design and implementation of the theoretical phenomenon of trapping force in the quantum field and analyzes the difference in trapping force when two different systems are involved. Our objective was to trap a particle and illustrate differences in trapping forces employing two different systems, specifically the crystalline structures of copper (Cu) and silicon (Si). Throughout the experimentation, we maintained a consistent adsorbate atom, helium (He). The primary aim was to validate the hypothesis that heavier atoms possess greater potential energy, resulting in enhanced trapping forces. This validation was pursued through numerous simulations using various software. The outcomes of this experiment unveil a spectrum of possibilities within the quantum field. Our future endeavors are centered on advancing the efficacy of trapping mechanisms, exploring ways to reinforce trapping capabilities further, and enhancing overall efficiency.

Bangla Plagiarism Checker using Machine Learning-Multiple line Approach
(North South University, 2023) Md Saiful Islam; Nabeel Mohammed; 1620578042
Plagiarism is the practice of representing another person's ideas or works as your own, with or without that person's consent, by incorporating them into your work without giving them due credit. So, there are some excellent tools available to identify plagiarism, such as Turnitin, Grammarly, etc. Even if there are many techniques available to detect plagiarism in a document, most of them are domain-specific and designed to operate with English texts, but plagiarism is not limited to a single language. With 300 million native speakers and 37 million second-language speakers, Bengali is the most frequently spoken language in both Bangladesh and India. In this project, we designed and developed a plagiarism detection method that makes use of Natural Language Processing (NLP) methods to deliver more precise results than traditional methods. We used some Bangla datasets, which are mainly based on a lot of articles from Bangla newspapers, and we also created a dataset using scarper. We processed the collected datasets and then merged them with the dataset that we made by scraping and categorizing it. Then we trained the dataset with different models and tested the results. After performance testing, we built a UI for Bangla Plagiarism Checker so that users can check the similarity based on our training dataset.

Object Detecting Robot Identifying & Picking Up Objects
(North South University, 2023) Raisa Akhtar; Zarin Musharrat; Alifa Khan; Md. Shahriar Hussain; 2012010042; 1931826642; 1931829642
This research focuses on the development of an accurate object detection algorithm to aid robots in identifying and picking up objects in cluttered environments. Object detection is crucial for robotic control systems, particularly in industrial automation. Traditional object detection algorithms struggle with objects lacking texture, leading to the adoption of deep learning methods like YOLO (You Only Look Once) for improved performance. The study aims to enhance object localization accuracy, especially in cluttered scenes, to facilitate robot grasping tasks. While basic YOLO models can detect objects, precise localization remains challenging. The research proposes a solution using deep YOLOs for semantic segmentation, which significantly improves object localization accuracy. Despite being time-consuming, YOLOv8 proves highly efficient, achieving an accuracy of 84.7%. The ultimate goal is to implement a robot capable of detecting and identifying five objects (ball, bottle, car, cup, spoon), and then picking and placing them according to user instructions. For the hardware part, we have used the Arduino UNO microcontroller, which is quite budget-friendly. As this is just a small test project, only a robotic arm gripper is used here, so that it can only grab it if it recognizes the object.

Chikitsa Nin: Real Time Web Based Remote Patient Management System using Internet of Things
(North South University, 2020) Md. Hasibur Rahman Fahim; Kho. Iftekhar Alam; Oyshee Rahaman; Hossain Ahmed Sojib; Tanjila Farah; 1612241042; 1510093042; 1611872042; 1610645042
Bangladesh currently offers six registered doctors for 10,000 patients, with a 43% vacancy in the required number of doctors. Here, the modernized hospitals are mostly urban area-based, and the scarcity of hospital accommodation is very real. Diagnostics are mostly private and out of reach for 24.3% of people living below the poverty line, and a hard call for almost 50% of the population who belong to the middle class. No professional medical consultancy is available here to find the best doctor in the field for emergencies, nor is there a hospital that provides the required service at once. Here, family members of critical patients, along with the patients, are often found running from hospital to hospital to check for the availability of their needed service. This suffering makes the “Chikitsa Nin” rise as a web application which creates a platform for its users to find a doctor to consult, get a medical representative to collect the sample for diagnosis, get required services from the hospitals around by choice, and medicine delivery altogether from one place.

In this project, we develop and design an online-based application. Travel Buddy is a FREE social networking app that helps you find travel buddies and partners for your backpacking or holiday plans. We developed this application to automate a travel agency. This client-server-based app will serve all the agents of a travel agency and record all the information of a passenger. The agency can discover all the money transactions and passenger services from remote places through this platform. This social networking app also supplies necessary reports. In this project, there is a login page for each travel agency employee. The admin user can define roles for all users with respect to their user type. That means the admin can authenticate which kind of user can see or perform operations on which pages. This online-based app is device-independent.

Design and Implementation of a Blockchain Enabled E-Voting Application to Prevent Multiple Voting Schemes
(North South University, 2021) Iftekhar Mahmud Tahir; Md. Sifaat; Md. Imran Hasan; Mr. Zunayeed Bin Zahir; 1520541642; 1632285042; 1711460042
This report presents a Blockchain-based e-voting application that can prevent voters from casting their votes multiple times. The first and foremost step in this system is to validate the voter's identity. At first, the voter needs to download the e-voting application on their mobile, laptop, or other smart devices. After that, the voter needs to submit their identity information, which is verified by the organization conducting these elections. The administrator will check the registered voters' database and confirm whether they can vote. Then all the voter information will be securely added to the Blockchain. After the voter's identity is verified, a smart contract will be executed to issue a ballot to vote and submit it to the ballot box in the application. The application will ensure that a user cannot vote multiple times. When a user casts a vote, the administrator will check the Blockchain to ensure the voter has not already used up their vote. If the user's vote is valid, the administrator accepts their vote. In case the vote is found to be invalid, the administrator rejects their vote. Once a user casts a vote, it becomes a transaction and gets stored in the Blockchain encrypted. Moreover, the vote cannot be modified because of Blockchain's innate immutable characteristics. The voter will be given the option to print the receipt as proof of casting a vote. Through Blockchain, the voter will be able to verify that their vote has been cast and counted. The voter can even audit each ballot in the ballot box and confirm if the election results are accurate while retaining other voters' privacy.
