(North South University, 0000) Amena Akter Sumona; Abdullah Al Noman; Anisur Rahman; Shah Sadad Ahmed Nabil; Zunayeed Bin Zahir; 1510209043; 1513174043; 1510652043; 1220793643
The consumer of electricity is increasing day by day due to many domestic and convenient electric devices like TV, fridge, lift etc. As a result, production of electricity has also increased over the years. Patrol, gas, coal etc are used to produce electricity, which causes environmental pollutions and global warming. If that goes on for too long, there will be a time when the earth may need to face the scarcity of all those resources in the near future. Consequently, there is a huge need for producing power from renewable sources. The reason for choosing gravity is that it is available everywhere on Earth and it does not diminish. In this project we present an electrical generator, which will be powered by gravitational and buoyancy force. The generator is divided in two parts, the mechanical domain and the electrical domain.

Design of a low voltage digital thermostat using LM35 and PIC Microcontroller
(North South University, 2013) Kaiser Alam; K. M. A. Salam; 072163045
This system is about the design of a low cost temperature sensing and control system (thermostat) with the use of PIC microcontroller and LM35 temperature sensor. The system is relatively inexpensive to make and can be integrated with temperature control systems such as air conditioners and fans. Apart from making temperature control systems more affordable for everyone, this system also helps save energy by automatically switching the devices on or off at the appropriate temperatures. In this project the LM35 and PIC16f877a microcontroller have been used to make a digital thermostat that is programmed to switch on and off a fan automatically when the temperature rises above or falls below a certain threshold value. The device also includes a LCD display to indicate the ambient temperature to the user. The threshold temperature can be programmed into the PIC microcontroller using a PIC programmer. The device as a whole works as a digital thermostat. Commercially available digital thermostats work at 24V AC typically. Some versions use a low voltage as low as 6V or as high as 30V. In this project the thermostat design allows it to operate at only 5V, making it more energy efficient than currently commercially available digital thermostats. The versatility of the system allows it to integrate with many different devices. Apart from air conditioners, furnaces and fans, this system can be used to build incubators or to maintain a constant temperature in your refrigerator at home.

AUTONOMOUS HEAT SEEKING ROBOT FOR WASTE HEAT EXTRACTION
(North-south University, 2018-04-30) ATKIA SAMIHA; FARHAD HOSSAIN SARKER; ROZA NASER KHAN CHOWDHURY; DR. SHAHNEWAZ SIDDIQUE; 1431038043; 1430648043; 1430697043
The main aim of this project is to maximize the use of waste heat energy. The objective of this project is to detect higher heat emitting objects or surfaces and extract wasted heat energy from that very particular area and convert it into useful energy, such as electrical energy. Like a radar system, the autonomous vehicle keeps rotating until it locks under a threshold value of temperature. The servo motors help the robot to rotate 360 degrees. It uses non-contact thermometer sensor to detect the presence of heat emitting objects or surfaces. The robot will keep moving towards the object, until it reaches the pre-set highest temperature. Once it reaches its destination, with the help of thermoelectric generations, it absorbs heat from that very particular area or radius and converts the unwanted wasted heat energy into electrical energy.

“Shonabondhu” An IoT based Flash Flood monitoring system
(North-south University, 2018-04-30) Rozana Tabassum; Maisha Mamtaz; Nabila Chowdhury; Dr. Nova Ahmed; 1331126042; 1411213642; 1430549042
Flash Flood is a natural disaster that floods away large area where there are dense presence of rivers within 3-6 hours of heavy rainfall. Bangladesh is one such country where people face this sudden flood problem and loses valuable assets due to lack of proper water level monitoring system as they cannot take precaution beforehand, especially in the rural areas. We are proposing a distributed system using water level monitoring sensors named Shonabondhu. The sensors are distributed near the rivers in the rural areas and the servers that collect data from sensors are used to send alert to the people. The servers use current water level and compare it to the danger water level that has been collected from the data of the previous years. This information is used and broadcasted when the water level increases near the source of the river. We have used our system to monitor the actual water level in the river and got satisfactory results from it.

Analysis Of PPG Signal Of Cardiac Disease
(North-south University, 2018-11-30) Ayesha Siddiqua; Nowshin Mostafa; Syeda Meem Rameen; Dr. Tanzilur Rahman; 1321214045; 1410858042; 1430477043
In this thesis paper we are presenting the result of analysis of Photoplethysmogram (PPG) signal of normal subjects and cardiovascular problematic subjects. Photoplethysmogram (PPG) is a non-invasive and inexpensive method for detection of cardiovascular disease. Photoplethysmogram is a technique that measures blood volume changes from skin which is close to arteries. PPG data were taken from 10 subjects and data were taken from subject’s index finger. Amongst 10 subjects 5 subjects were cardiovascular problematic patients and 5 were normal. Primary cardiac problem detection technique is Electrocardiogram (ECG). ECG is also a noninvasive technique but ECG is expensive compare to PPG. ECG machines are big, not portable and very expensive to have individually at home. ECG is more suitable for hospitals. ECG tests are also expensive. It will cost very large for anyone who wants to keep going on tests of cardiac disease detection at early stage. Compared to ECG PPG is very small, portable and inexpensive. All kind of people can afford PPG based system for cardiac detection at home. In this paper we presented two methods based on PPG signal to analyze cardiac disease one is pulse amped sensor and other one is smartphone. This paper presents all the research, techniques, and algorithm development to analyze cardiac disease using pulse amped sensor and smartphone both individually. Pulse sensor is affordable and 2.1 billion or more people already uses smartphone today's time so any system based on both or any of the way will be low cost and great for early detection of cardiac disease at home or anywhere. Pulse sensor and smartphone both can be a worth alternative of ECG. We hope this study will be valuable to create both or any of the monitoring system for cardiovascular disease detection.

HOME AUTOMATION SYSTEM USING BRAIN WAVE
(North South University, 2018-11-30) Mahmudur Khan Tanzid; Zobayda Hossan Arshie; Saima Islam; Shahedur Rahman; Dr. Mohammad Monirujjaman Khan; 1410082042; 1410288042; 1420449645; 1321732043
Brain-computer interface (BCI) is a communication pathway between the brain and the external peripheral devices like computers. We propose to use this technology for Home automation. Home automation can be totally revolutionized using BCI. The brain produces various types of waves like alpha (9-13Hz), beta (14-30Hz), theta (4- 8Hz), delta (1-3Hz). Using these waves we can control various home appliances. The entire concept consists of 4 main stages of detection, amplification, processing, output. First detecting the brain signals using an EEG cap or electrodes. These brain signals are very weak hence in the second stage we need to amplify these brain signals to a usable amount and filter these to remove noise. Then thirdly, we will have to convert these signals into digital by using A to D converter and into a type, a computer software or a microcontroller can understand. Fourth, taking this decoded signal and sending these signals wirelessly, by using an RF circuit to a distant switch circuit, which will turn on or off the appliance in the vicinity. Using this technology, the life of people would be further simplified, physical efforts would be considerably reduced and it would also prove as a boon for physically disabled people.

Collaborative Box Pushing by Swarms of Homogeneous Robots
(North South University, 2018-12-31) Mostafa Shahriar Shohad; Atifur Rahman; Tanvir Ahsan Tantu; Sharmin Sultana; Dr. Sifat Momen
Multi-robot systems in everyday use are the next big thing of the future. Division of workload is a very basic field of research in these type of systems that have many agents working together. This very basic phenomenon of load distribution is seen in many living organisms in the world, such as, ants, honey bees, termites, etc. When they are annoyed or disturbed by an internal or external factors, they show attractive abilities to distribute errors in order to counter the situation. Using these examples from nature, we can design new systems and build a framework that can handle complex real world issues by division of workload. This projects aim is to look at how swarms of homogeneous robots collaboratively carry out a task. The project is about a group of robots that can push a box while staying together in a flock. They will be able to detect obstacles in front of them and get past them. They will also be able to detect whether the obstacle in front of them is a robot or not. The main objective of this project is the distribution of workload among small homogeneous robots to execute a specific task, which is to push a box that is heavy enough for a single robot to push. In the near future, this project will help researchers to know more about swarm behavior and the allotment of task between multi-agent systems.

(North South University, 2019) Istiak Rahman; Zareen Tasnim; Farzeen Ahmed Bashori; Mahdy Rahman Chowdhury; 1530861642; 1511908042; 1510223642
Bangladesh has a lot of potentialities and possibilities as a third world country if it utilizes the blessings of technology properly. With the help of recent technology, different time series analysis models have been developed like ARIMA, ARIMAX, SARIMA, SARIMAX, and even a Facebook developed module called Prophet. Nowadays it is possible to detect the future trend of any business given any type of data. We have applied a similar approach to predict sales for one of the flourishing startups of the country named Rokomari.com. The struggle for any company is to sustain amongst its powerful competitors in its emerging years. It becomes easier to ace over the competitors if the company can have a prior preparation of its upcoming challenges. Our effort was to make the journey smoother so that it can sustain in building a flourishing business amongst its competitors. In order to do so, we have worked with “real world” sparse dataset of the company itself. We were successful in predicting their possible sales for coming years using time series models like SARIMA and Fb Prophet. The paper discuses briefly about the significance and possibilities created due to implementation of our custom build software.

There are traditional ways that we have used to control and deal with the after math of fire hazards and natural calamities like earthquakes and cyclone. But as the technology has developed in recent years we have come up with a more innovative method to tackle this problem which we believe can save more lives. Our solution is PHOENIX. It is a pair of drones that are designed for surveillance and survival package delivery in the case of a disaster management. The reason why we chose to work with drones is because one of the major aspect of a drone is that it can reach where a person cannot. In many disastrous situations that is a major factor in saving lives. Traditional methods has to work from a distance and is inaccessible in tight places. Our drones can provide an overview of the whole effected area and show exactly where to send rescuers and resources to save maximum lives and goods. In case of disasters these drones can be used for surveillance and also for deployment of fire extinguishing agents and emergence survival kits. These small changes can cause a major difference in a life and death situation. We believe that in the right hand our project can save a lot of lives in disaster situations.

Drones have become very common these days in the entertainment field. People use drones to take amazing videos and pictures of landscapes. We have used this entertainment device in a more helpful way with which we can solve real world problems. Our drone has features such as surveillance, object detection and crowd detection. The main idea of our project is aimed to ensure precise and fast surveillance throughout a specified area using autonomous surveillance. It is aimed to be used for violence detection, law breakers and any other objection that pose a threat to the law. It scans all the places that CCTV cameras cannot cover and reports back live video feedback to the security personnel. Our work mainly aims to improve surveillance technologies and shape a secure compound. With the rise in security issues in the past decade, many people have resorted into unfair means of conduct. Also, with the rise of technology, it has become easier for law breakers to plan about an event without any security officials knowing about it. CCTV cameras are sometimes able to catch the intruders but, in most cases, due to the angle in which the camera is set to, many crimes go unnoticed. Our drone can detect any unwanted object or unauthorized person inside a given territory. Moreover, if there is any crowd which can pose a threat for the security concern, our drone can autonomously detect the crowd and send notification to the nearby security personnel.

In this report, we have explored the idea of automation in regards of hydroponic system. The purpose of this project was to make this process more manageable and accessible for the masses so that the people of Bangladesh can re-establish the slowly falling agricultural sector with advance new technology. As the unemployment rate is increasing and people are looking for new ways to stabilize the growing economy that people of Bangladesh has worked hard for, the most lucrative offer can come from the most back dated sector of our country, thus the hydroponic system. Hydroponic system can be the emancipator of our agricultural system, albeit the venture is quite risky due to the fact that we lack both knowledge and resources. Since, hydroponic system present itself as something of a sacrilege, which more often than not, people tends to avoid. Furthermore, with the backward technology we have mixed with the lack of understanding, most of the enthusiast either gives up half way or are still struggling. Ergo, this project is aiming to help the entrepreneurs to invest in agriculture so that we can not only reinvent our agriculture sector with new generation of young people, but also provide the country with adequate food, medicinal plant, foreign plants etc. We are integrating internet of things (IoT) and cloud computing to ease the hydroponic system, which requires constant maintenance, so that the new comers has more access.
