- 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.
- ItemOpen AccessImplementation of Cellphone Detector with Signal Jammer(North South University, 2022) Asif Hasan Akash; Tamzidul Haque Riaz; Shibly Ahmed; Md. Mahedi Hasan; Md. Eliush Molla; Dihan Md. Nuruddin Hasan; 1731261043; 1731703643; 1731489043; 1731343043; 1731041043This research have been done to restrict the use of cellphones in restricted areas and to increase security. Sometimes people go to the extent of using mobiles in prohibited areas, due to such acts the security policies of those places are hindered and the effects might be hazardous. Therefore to find an answer to that problem with the help of this study a solution can be derived. A device can be set up which will consist of a cell phone detector with signal jammer. In the current market, basically these are two separate devices i.e., a cell phone detector and a signal jammer but they don’t serve the purpose completely as the detector can only detect signals but they can’t block them whereas the jammer can only jam the signals but they cannot detect it, and we cannot let the jammer turned on continuously as it may harm the environment. But if we combine these two devices and make it a single handy device then our purpose can be served.
- ItemOpen AccessKrishi House An IoT based smart greenhouse(North South University, 2021) Moumita Ferdoushi; Shorony Mehtaz Ahmed; Ashfia Binte Habib; 1631125045; 1331066045In Bangladesh, one of the main economic activities lies in the agricultural sector. Although the good presence of resources does not produce results equal to the availability. The cause of scarcity and incompetent use of technology, deficiency of knowledge and awareness among the agrarians, methods which are time-consuming, hard labor, and more expensive in the long run. A Greenhouse is a technical approach in which farmers in rural areas will be benefitted by automatic monitoring and control of the greenhouse environment. The project focuses on the use of IoT in the greenhouse for environment monitoring and control by implementing low-cost, space, and effort strategies. A system that is efficient in terms of power and water usage while keeping the system architecture and design modest. Krishi House is semi-automated making human supervision redundant. With the help of a temperature sensor, soil moisture, pH and humidity sensor, light sensor the system will take inputs from the sensors to the microcontroller and microprocessor of the greenhouse where the algorithm will give desired output in form of irrigation, growth light, and system alert along with sending data wirelessly to the user. Power efficiency is attained by the use of solar energy when acquired; cost and space efficiency is achieved with a meticulous selection of components, materials, and horticulture technique. The goal is to have a competent semiautomated eco-system that supports different types of vegetation which will provide a better yield than the traditional farming method without the hard labor keeping cost and power use at least. The data collected throughout the experiment by the microcontroller and the microprocessor are attained wirelessly in a cloud database and can also be seen by a mobile app at the user’s convenience. The goal is to achieve a High-tech greenhouse with automation without the extra cost. The use of IoT and technological advancement will improve the agricultural prospect drastically in Bangladesh which shall be economically accommodating.
