A Study on Renewable Energy with Parabolic Trough Solar Energy Basis in Bangladesh Perspective- a Review and Discussion
(North South University, 2020) Md. Fazle Rabby; Mahdy Rahman Chowdhury; 1621372043
Generally, solar irradiation concentrates on the downcast part of the receiver tube in the Parabolic Trough Collectors. But nowadays we can see that the above method causes high temperature, thermal stress, tube deformation and energy wastage and so on. To fix the method properly and to apply it in our country in various purposes, the absorber or receiver tube should be rotated with the appointed frequency to ensure the energy taking process from the sun and then it will reduce the surface temperature and it will increase the solar energy absorption. Iâve studied a lot of research papers and I wanted to make a review paper which will be a selfcontained paper in the perspective of Bangladesh and a necessary and informative paper to all. One of the main and new thing that has come out for the benefit of research is that nanofluids play an important role to increase the efficiency and the speed to collect the energy from the solar irradiation. It can carry the heat of the absorber and improve the skills of the system. On the other hand, it is confirmed that here must be needed a reflector shield which is using as the experimented increment skill. Reflector shield is used for the receiver tube as secondary reflector and it has been reflecting inner surface. Main purpose of the reflectors are to achieve the higher expansion of the energy in the collector. The final result of the experiment shows that these two techniques improve the heat transfer coefficient and the thermal efficiency of the thermal collector. More exactly, the practice of nanofluids and reflector shields cum absorber tube increase the collector efficiency by more than 10% while the geometry progress increases the efficiency by 13%. Moreover, my study has shown how efficient Bangladesh is geographically and finally I gave an example of a PV plant. I emphasize the description here, so that it is self-contained in a very neat form and in different categories, so that we can selectively apply them conveniently and hope that this research will be useful as a source of information.

(North South University, 2020) Sajjad Mahmud Khan; Sajjad Kashem; S M Imam Jahed Hossain; Mayen Uddin; Mohammad Monirujjaman Khan; 1421222042; 1330273042; 1511913642; 1511500642
The rise of population and the industrial revolution, it is obvious that hotels and resorts are increasing drastically day by day. In 21st century tourism is a trend. Everyone loves to travel and the reasons vary person to person. Whether it is to have a cheerful and peaceful mind and place or business purposes, either way hotels and resorts actually doing their jobs very well. This, tourism is a promising sector for any country and Bangladesh is no different. But the problem is we have to do the hotel booking and reservation manually most of the time. Sometimes it is too troublesome and knowing about the suitable hotels and resorts is too difficult. Though there are some online platforms available but they are not our country oriented such as the payment system is not preferable for us. To solve this problem we developed Vhromon, a comparison based online based hotel and resort booking system where anyone can book a hotel or resort by just login from the internet. Vhromon is an interactive online platform and it is user friendly and easy to get like the most of the platforms available nowadays. But they do not have all the hotels and resorts enlisted, only the well-known one. On the other hand, Vhromon has everything enlisted where customer can compare them and can choose the right one for them. Furthermore we have a vendor panel where any hotel or resort owner can add their hotel or resort easily without any hassle unlike the existing one.

(North South University, 2021) Mohammad Rakib Hasan Tipu; Md. Al-Amin; Joy Saha; Atiqur Rahman; 1530174042; 1520179642; 1520715042
Agriculture is the root to a country's economic development. In recent times, huge scientific advancement has been implemented in various agricultural fields for the betterment of the future. Despite various researches, proper assessment and productivity couldnât be reached. We have tried to focus on different scientific applications which could be put together in the agricultural field for better accuracy with better productivity using less man-power. Moreover, we include a method for monitoring the agricultural fields from any remote location and assess the basic condition of the field. We also use solar tracking systems to generate the required renewable power supply in agriculture fields that could lead to an eco-friendly way of energy production, leading to a proper step towards the next green world. Bangladesh economy draws its main strength from the agriculture sector. The sector contributes 19.10% to GDP (at current prices) and employs 50.28% of the labour force. However inadequate management practices are one of the driving causes for agricultural productivity to be reduce din Bangladesh. The use of fertilizers, quality seeds, and irrigation together cannot ensure sustainable production unless timely and appropriate measures for the management of other nutrients are simultaneously pursued. Therefore, this project proposes a completely innovative, user friendly technology that assists farmers in maintaining their irrigation without any effort.

(North-south University, 2021-04-30) Tamjid Iqbal; Bratita Das Bristi; Abdullah Rakib; Tanjila Farah; 1512198045; 1520743642; 1410111042
With the growing amount of vehicles on the road, the number of fatal crashes resulting in considerable loss of life is also increasing. Various researchers have focused on developing particular road safety applications or crash avoidance programs in order to mitigate such road accidents. Image-processing-based tech is one of the latest road safety applications, but it will only operate effectively if the car is in line-of-sight with the camera and its output in poor weather circumstances involving dense clouds, heavy rain, and so on. As a response, the focus of this paper is on the implementation of a quality sensor-based system that can assist drivers in minimizing some kind of road accident in order to save lives. The main value of our proposed protective measure program is that it will anticipate the occurrence of a collision and, as a result, determine the driver's corrective behaviour and expectations to prevent a collision. Furthermore, our proposed system can be implemented on any existing vehicle and therefore would not necessarily entail the construction of new roadside facilities. The proposed collision avoidance solution is also valuable since it requires an amount of good sensors such as ultrasonic sensor nodes, speed sensors, GPS, Wi-Fi module, and on and on.

Hydroelectric power plant management is an extremely common project all throughout the planet. Also, it is an especially accommodating and worthwhile framework, yet it costs a lot of money to fabricate a hydroelectric power plant. Use of renewable energy is an essential ingredient of socioeconomic development and economic growth. Renewable energy sources such as wind energy, tidal energy, etc., are abundant and can help in reducing the dependency on fossil fuels. So, we contemplated something that can be both advantageous and cost a modest amount of money to implement a power project. In this manner we found a Hydroelectric project with the assistance of current innovation and modern technology, which is a simple task and it will not set us back a great deal of money and it will be easy to build in a riverine country like Bangladesh not to mention is eco-friendly for fishes as they will be able to move through the whole procedures. It will follow basic physics, which is kinetic energy collected from water.

(North South University, 2021) SK Kamal Hossain; Shaifur Rahman Shawon; Mohammad Sifat Hasan; K. M. A. Salam; 1712573042; 1712760642; 1721748042
Now, it is the public transportation system, likely the metro, that is well advanced. Passenger safety, convenience, and the need to improve the performance of existing public transportation are driving demand for intelligent transportation systems in the market. The paper-based ticket system for collecting the bus fare has been found to be a source of major financial loss in Bangladesh. It is difficult to ensure the purchase of a ticket by each and every passenger. An automatic bus fare collection system is implemented using a smart card. A smart card is given to the passenger, and when the passenger gets into the bus, he/she has to swipe the card in the RFID reader, and the device will automatically calculate the fare and deduct the money automatically. The manual fare collection system has many issues that are overcome by our proposed system. An automated fare collection system for public transport using GPS is an innovative idea that reduces manpower. The ticketing systems using RFID can be merged to solve the above-mentioned problems. This project actually suggests a much more public-friendly, automated system of ticketing with the use of RFID-based tickets. This project actually suggests a much more public-friendly, automated system of ticketing with the use of RFID-based tickets.

(North-south University, 2021-11-30) Md. Mukith Al Alim; Md. Ashiqur Rahman Ovi; Md. Hasibul Hasan; Zeeshan Jamal; Dr. Shazzad Hosain; 1711376042; 1721444042; 1722351642; 1731699642
This paper represents a noble approach to develop a Machine Learning method like Ecommerce Based Product Recommendation System for developing country like Bangladesh. The product recommendation system is a filtering system that seeks to predict and show the items that a user would like to purchase. Recommender systems have become increasingly popular in recent years and utilized in various areas, including movies, news, books, research articles, search queries, social tags, and products in general. It is an essential feature of the digital world. Because users are often overwhelmed by choice and need help finding what they are looking for. If a recommender system is set up and configured properly, it can be the reason for a significant boost in revenues, satisfied customers, and more sales. In this project, we have employed several machine learning algorithms (NCF, SVD, Encoder-Decoder, KNN) to build a recommender system for products and also have developed a website through which users can geta list of recommendations of products based on their preferences. These algorithmsâ performancesare evaluated on different metrics. KNN has been selected to deploy on the website among all the algorithms.
