    Sleep apnea is a common and potentially serious sleep disorder that affects an estimated 22 million Americans and is characterized by repeated episodes of shallow or stopped breathing during sleep. These episodes can lead to disrupted sleep and decreased oxygen levels in the blood, which can have serious consequences including high blood pressure, heart disease, stroke, and even death. A real-time sleep monitoring system using Internet of Things (IoT) technology has been developed to detect and alert individuals to sleep disorders such as sleep apnea.The system developed in this study includes sensors that measure various physiological parameters, including electrocardiogram (ECG), heart rate, pulse rate, skin reaction, humidity, temperature, and SpO2, during sleep. These parameters are continuously monitored and any unusual patterns or events are detected and alerted through a mobile application. The mobile application has been developed using MIT app inventor. It shows us the level of the parameters and any abnormality in health can be detected through it. This study is particularly valuable since it can test sleep indices without waking the user and display them in a mobile application at the same time using a Bluetooth module. The system has been designed in such a way that it may be utilized by anyone. Multiple analogue sensors are used in conjunction with the Arduino UNO to measure various sleep factor factors. The method was evaluated and tested on the bodies of many persons. The device watches multiple people as they sleep in order to evaluate and identify sleep apnea in real time. According to our findings, persons with significant heart and lung problems suffer sleep apnea. Sleep apnea is more common in persons over the age of 60. This study also examines those who are not at risk of sleeping disorders based on the data obtained. This document will help everyone learn about sleep apnea and will assist individuals in detecting and preventing it.

    AI-Powered Smart E-commerce Web Application with Blockchain Integration
    (North South University, 2023) Md. Shamim Ferdous; Salman Yousuf; Tasrifa Hossain; Mohammad Monirujjaman Khan; 2013080042; 2012927042; 1731779042
    This report introduces an AI-Powered Smart eCommerce Web Application seamlessly integrated with Blockchain technology. The project aims to enhance the security, personalization, and efficiency of online shopping through the integration of advanced technologies. It is in its completed state, which now has a multilingual AI chatbot, a machine product recommendation engine, and blockchain integration with a mainstream payment processor. The project follows a methodology that includes the use of Python, Django, PostgreSQL, NodeJs for Backend and JavaScript, ReactJS, NextJs for Frontend development. The results include a smart e-commerce platform with superior autonomous customer service, personalized and efficient user experience and safe and transparent payment processing. The web application received an overall grade of “A” from GTmetrix with the largest content paint time of 277 milliseconds. Google’s PageSpeed Insight gave the application a score of 97% for performance and 79% for accessibility. The product recommendation engine has obtained an accuracy of 0.9926. Integration of the blockchain ensured the immutability of the transaction records. The AI chatbot was able to reply to customer queries in English, Bengali, and Romanized Bengali. This project positively impacts society and the economy by creating job opportunities and contributing to the growth of the e-commerce industry.

    Animatronic Hand Controller
    (North South University, 2019-04-30) ABDULLAH AL ASIF; ANIKA TAHSIN; Dr. Mohammad Monirujjman Khan; 1520374643; 1520307643
    This project is developed to eliminate the using of the bare hands for handling any kind of risky item which are harmful for our own hand. For some time, we have been interested in making some sort of robot based on the Arduino platform. This project is the first phase of this longer-term desired effort. Anything is possible with the mighty power of Arduino. It's compact, it's straightforward, and makes embedding electronics into the world-at-large fun and easy. Animatronics is the use of mechatronics to create machines which seem animate rather than robotic. Animatronic figures are most often powered by pneumatics (compressed air), and, in special instances, hydraulics (pressurized oil), or by electrical means. The figures are precisely customized with the exact dimensions and proportions of living creatures. Motion actuators are often used to imitate “muscle” movements, such as limbs to create realistic motions. Also, the figure is covered with body shells and flexible skins made of hard and soft plastic materials. Then, the figure can be finished by adding details like colors, hair and feathers and other components to make the figure more realistic. The project idea came to us after watching the movie named “Real Steel”. We wanted to make a shadow robot from our curiosity. As the whole body of the robot would have been of much cost, we decided to make a shadow hand instead. Approximating the kinematics of the human hand was our top priority when developing this animatronic hand. Each joint of this hand has a movement range again the same as or very close to that of a human hand, including the thumb and even the flex of the palm for the little finger.

    A web application that detects malaria infected red blood cells in real-time
    (North South University, 2019-04-30) Fariha Islam; Porsia Tithi; Biswas Nazimuddin Nadim; Dr. Mahdy Rahman Chowdhury; 1511602042; 1420674042; 1410291642
    Bangladesh is considered as one of the malaria endemic countries in South Asia hence detecting it at an earlier stage and being able to keep records can save life. The Pathology Assistant is a web app built for Pathologists to be able to create patient profile, upload red blood cell images which is stored in the database and run through a neural network. The neural network can perform binary classification which can tell the pathologist whether the red blood cell is malaria infected or not. This way the pathologist can keep track of the patients condition and upload more images time to time to check the improvements of the patients condition in real time.

    ExoArm: Patient Rehabilitation, Mobility and Heavy-lifting, using COTS products
    (North South University, 2019-04-30) Tanzim Bin Khalid; Kazi Azmain Faieq; Md Muhtasim Alam Chowdhury; Dr. Shahnewaz Siddique; 1520894043; 1512200643; 1520334643
    Exoskeleton, a revolutionizing new term which has taken the world of technology by storm in the last few decades. A technology, improving at a rate faster than anticipated. Some living organisms are found to be naturally supported by external skeletons, giving birth to the concept of exoskeleton where human beings who are physically disabled are to be supported by an external framework to support and aid them in their day to day activities. Therefore, using the concept of exoskeleton we plan to build an automated, at the same time independent, mechanical arm for rehabilitation and providing aid to the people who are suffering. In addition to the primary goal, our device will also be able to aid people without any disabilities, in performing daily chores or lifting heavy objects. We plan to execute this system using commercially off the Shelf Components (COTS) such as: Arduino, Myoware Muscle Sensor and Linear Actuator, having researched on efficiency and cost of other relevant components. The sensor will sense the EMG signals from the targeted muscle group, the Arduino will convert these signals to analogue values and eventually send in the commands to linear actuator for execution. If successful, affordability and reliability will be maximum, making sure such a high-end product is available for the masses.
