- ItemOpen AccessSmart cane for visually impaired people with obstacle, staircase and water detection along with location tracking feature(North-south University, 2017-12-31) Hemal Saha; Fazlay Rabbi; Anika Tabassum; Mohammad Rezaul Islam (IMR); 1310821043; 1310967643; 1330024043Around 7.6 million people in Bangladesh are visually impaired and approximately 1.1 million are blind. They are deprived of one of the most essential sense. Our main purpose was to lessen the struggles of our country’s visually impaired people. White canes are usually used by has many limitations like detecting objects properly, detecting stairs, head-level objects etc. Moreover, currently available modern systems are costly, thus unaffordable for poor people. Therefore, we are proposing an Arduino based low cost smart cane with multiple sensors which will help a blind person with safe navigation and make him or her more independent. Our final design is quite cheaper than existing alternatives and warns the person via vibratory signals. Our device will be able to detect obstacle, upstairs & downstairs, and presence of water. The device will notify the user by vibration. Our system is also able to provide the location of the user to a particular person in case of emergency. After testing the cane in various situation like educational institution and busy streets we have found it very useful and efficient. There is also a RF remote controller as cane locator for the user to find the device easily.
- ItemOpen AccessIoT Based Home Automation Solution with Energy Monitoring Features.(North South University, 2017-12-31) Noor Al Din Ahmed; Rahatul Aine; Dr. Tanzilur Rahman; 1310607043; 1220812042IoT (Internet of Things) based Home Automation system signifies the application of computer technology and internet for controlling the home appliances easily and remotely from any place in the world. As technology is evolving day by day and almost every equipment is getting automated, so there is seen a gradual increase amounts of automation in homes around the world because it reduces human labor and provides ease and comfort in people’s busy lives. Our project represents a semiconductor based Home Automation system which can control the switching of the power outlets in terms of controlling various electrical appliances, such as lights and fans or any inductive load that can be voltage regulated and switching various devices on and off. This system contains a Zero Crossing Detector (ZCD), a Thyristor based switching circuit to control the power output to the loads and also a Web Server along with a database and API functionality since the whole unit needs to be controlled through the web. Although, the Home Automation is becoming popular worldwide, it is not vastly being used in Bangladesh because establishing a Home Automation system seems very costly to the majority of people in here and besides, many people here are still not technologically literate where they cannot directly interact with computers. Thus, our proposed system brings a solution to this problem which is affordable, convenient and simple and requires minimal knowledge for users to operate it. This system can not only be implemented in residential buildings but also can be used in office buildings, hospitals etc to manage certain room conditions
- ItemOpen AccessBangla Text to Speech With Emotion(North South University, 2022) Shaif Hossain Emon; Maruf Mustar Moon; Md Farhad Gazi; Md. Riazat Kabir Shuvo; Md Shahriar Karim; 1811603642; 1811009642; 1621760042; 1621535042Spoken language technology improved a lot. There are many text to speech models like tacotron, tacotron 2, deep voice, Fastspeech, and wavelet are used for synthesizing speech. Tacotron 2 has a 4.58 mean opinion score, mostly human-like speech generated by a computer. There is no work done for an emotional Bangla text-to-speech. This paper proposes a transfer learning approach for generating emotional speech with the respective tacotron two models. We have created a Bangla Emotional Text To speech web app. It generates Bangla speech for a text or audio input with a specific emotion. Initially, it gives speeches for three types of emotions and the poem. Users can choose which kind of emotions they want in the speech. Then their text will go to one of our tacotron two models. We have three models for creating sad, neutral, and happy speech. We have created another model for reading poems. For training our sad and happy model, we have built our dataset.
- ItemOpen AccessDetermining Physics Law From Moving Object(North South University, 2020) Sharara Sartaj; Sanzar Rahman; Mohammad Ashrafuzzaman Khan; 1620169042; 1621555042Computer vision is an interdisciplinary scientific field in Deep Learning that deals with how visual images or videos can help computers achieve high-level understanding. It attempts to understand and automate tasks that the human visual system can do from the perspective of engineering. The soul of Computer Vision is Detection and for our Project we are trying to determine any physics law from a moving object using Deep Learning algorithms and techniques . As the initial step we have trained our Deep Learning Model to detect a sports ball from a picture and also from video. The accuracy we got was quite good but now we are trying to track the ball in continuous time frame without dropping it for a second. Our next steps will be getting the coordinate values of that ball from a video and then using those values we will try to compare it with curves that any law of physics follow which is the main goal of this Project.
- ItemOpen AccessIOT Based Women Security System(North South University, 2021) Audhora Islam; Pulok Adhikary; Monika Zaman; Shohana Rahman Deeba; 1230830642; 1430234642; 1711940642At present women alongside men are working in different sectors like banking, offices, garments sector and almost in every sector. As the women are working in different sectors alike men, the women also have to work in odd times and situations in order to prove their worth and this leads to the fact that they have to leave their workspaces late hours at night, some may have to go to school, college and universities through some roads which are deserted even during at noon or afternoon. Most of these times, the woman or girl is being teased, even physically harassed or abused. Some of them are also being abused even in crowded places like the bus stands, rail stations, even in the rented taxi or cars they take to come home. These reasons leave a woman to be feared and not go out in the streets. They along with their parents always have these haunting thoughts in their mind that if they step out of their home will they be able to reach home safe and sound. At present even during these worst times of COVID19, the rate of physical abuse has also been increased at an alarming rate in Bangladesh, so it has become a demanding issue for every woman that if there had been some device or something that would have helped the women or ask for help in the time of harassments. Keeping these things in mind, in this research paper we will be proposing a smart system using IOT and hardware, by which a woman would be able to ask for help and alert the nearby police stations without even alerting the attacker. In the first part of this paper, there will be a discussion about the problems that are faced by the women and the existing systems to help the women in need of help, then there will be the statistics of rate of harassment issues over the past few years. In the second part of our paper, there will be discussion on the proposed system using IOT and different hardware, besides we have also tried to keep the cost minimum so that this system is cost efficient for every woman. We have kept the call for help as the main priority because there might be some time even when the women are able to get her out of the situation, there might be a chance where she might be physically harmed. As a result, we need to make sure that the help the victims are asking for is received. We-RUS is an app and IOT based smart system which will be able to locate the victim and will send alert messages to the emergency contacts of the victims and the ones that are using the app nearby to and main and important part to the police station. Now there might be times, when the alert or the help call from the victims are not being received, so we also developed our system such that when the message will be send to the emergency contacts it will be sent as an alarm so it even if the phone of one of the emergency contacts of the victim is silent, the alarm will create vibration and thus one must have to check their phone and thus the help asked is received.
