Computer Vision Based Industrial and Forest Fire Detection Using Support Vector Machine (SVM)
(IIUC Central Library) Rahman, Md Abdur; Hasan, Sayed Tanimun
Burning issue is a very serious issue nowadays in our garments and industries sector. The workers are facing the problem and losing valuable life. On the other hand, investors are losing their hope in this sector. In this paper, we have propounded a vision-based system which is capable to detect fire. We have developed a pipeline model consisting of Background Subtraction, Color Segmentation, Special Wavelet Analysis & a Support Vector Machine which will detect real-time fire and smoke.For SVM model we have trained the dataset in two ways. One is the different kind of fire image and other is the image that looks like fire but it’s not fire. If the situation is breaking out of fire then the system will immediately raise an alarm and an automatic SMS and email will be sent to the authority and nearby fire station. In this study, the proposed strategy works on a very large dataset of fire videos that have been collected both in real life situations and from the internet.In this SVM pipeline model shows the maximum accuracy is is 93.33%. The system can fulfill the precision and detect faster real-time fire detection. Its industrial application will aid in the early detection of fires, as well as emergency management, and so greatly contribute to loss prevention.

(IIUC Central Library, 2011-04) Ahmed, Shafait
Engineering is not only a theoretical study but it is a implementation of all we study for creating something new and making things more easy and useful through practical study. It is an art which can be gained with systematic study, observation and practice. For that sole purpose I choose to do my project on something new and innovative. In my project I tried to introduce a new trend to the home security system. I named it as “Design and Implementation of an Intruder Radio and video Alert System”. In it I choose a voice recording a play back IC which can record an emergency voice message and plays it when security of the house is disturbed in any way. Along with that I thought it beneficial if the message can be transmitted so that it can be heard in radio. Furthermore I choose a microcontroller for automatic operation of the voice IC on the basis of various sensing system. It’s a very good security system which will provide more security for our home.

(IIUC Central Library, 2011-06-18) Chakma, Rocky; Alam, Rashedul
The aim of this project is to make a sine wave instant power supply and analysis the effect of different types of load on home appliances. There are many types of Instant power supply (IPS) in the market. Most of these outputs are PWM and the efficiency of these are less than sine wave IPS. But the sine wave instant power supply (IPS) are costly than other instant power supply. The instant power supply mainly contain with two parts. The first one is inverter part which convert 12VDC to 220VAC.The second part is battery charging part which charge the DC source. The output from the inverter part is sine wave. The efficiency of this sine wave instant power supply is better because output of the other instant power supply is square wave. This instant power supply is cost effective than other types of instant power supply.
Design and Implementation of a Wireless Multi-meter
(IIUC Central Library, 2012-11) Hossain, Md.Shahed; Uddin, Md. Jashim; Chowdhury, Md. Shoyaibur Rahman
A wireless multi meter is an instrument used to measure the current, voltage, frequency and power at a load from a distance. In this project a wireless multi meter was designed which consisted of two major parts: 1) Measuring Section Module and 2) Remote Display Module. Measuring Section Module consisted of three major section which are i) signal input, ii) Micro controller, iii) RF transmitter whereas the remote display module also consisted of three parts i) RF Receiver, ii) Microcontroller and iii) LCD Display Module. At first the signal under measurement, was converted to a 6 volt signal through a transformer and was fed to the microcontroller (ATmega8A) input. After all relevant calculations the dc voltage produced by the micro controller was sent through an RF Frequency transmitter module (BX-R433A) having an omnidirectional antenna. The RF receiver module (KSTRX806E), situated at a maximum distance of 150 meters from the transmitter, received the transmitted data and the microcontroller next to it was used to decode the signal intercepted by the receiving antenna. The result of the calculations is then displayed through a 16-bit LCD display module (TM162A). This multi meter was found to measure the values of the voltage, current, power and frequency ranging from (0-250) V, (0-20) A, (0-5000) VA and (0-125) KHz respectively. The main attraction of our designed circuit was the simplicity of the circuit, easiness of implementation and the availability of components required in our country.

Grid Integration of Renewable Energy: Sinusoidal Pulse Width Modulated Inverter
(IIUC Central Library, 2013-06) Kibria, Syed Golam; Islam, Atiqul
Mobilizing and generating affordable as well as environment friendly energy resources is one of the key challengers for any nation in today’s world. Today the top priority for Bangladesh is Energy and Power generation. Presently, out of around 161 million populations, only 40-41% has access to electricity. At least to bring the populations into the facility of electricity access as much as possible within the limited resources, we can utilize the natural resources to fulfill this expectation. Using solar or wind energy in association with the power electronics devices, we can supply the electricity to the consumers within their ability and we will be able to minimize the power problem as possible. Pulse Width Modulated (PWM) inverter is the combination of power electronics devices which reduces the major crisis of costs, where costs are the big issue for developing country like Bangladesh. Now-a-days, the integrated circuits (IC) are so reliable and cheap that make the carrying and inverting or converting elements easiest than the bulky and costly instruments used in the conventional power supply system. We expect that the grid integration of the renewable energy resources using pwm inverter may cause a tremendous remark in fulfilling the lack of power utilization across the world.

(IIUC Central Library, 2014-06) Hossain, Md. Emran; Siddiquee, S.M. Shahnewaz
Base Transceiver station (BTS) is a set of telecommunication network that organized as tower with transmitter and receiver antennas. The function of BTS is power amplification so it can connect the telecom operator networking with customers. Power is the main issue for telecom operators to set up cellular network coverage in remote or isolated areas. Power generation by combining both renewable and conventional sources known as hybrid power generation, can be the most efficient way for electrification of Base transceiver station (BTS). The aim of this thesis is to determine the optimized system configuration of PV based renewable hybrid system for remote off-grid BTS sites as well as grid connected BTS sites in Bangladesh. The possibility of supplying electric energy from solar-wind resources to the BTS is also investigated. For this analysis three case study is considered. We analyzed the possibility of using renewable source for both off-grid and grid connected BTS taking Chittagong as reference site. The final optimization of the renewable based hybrid system is carried out through Hybrid Optimization Model for Electric Renewable (HOMER) software to find out that whether the system is feasible or not for proper electrification in the BTS.

A thesis on Robust Droop Controller for Accurate Proportional Load Sharing among Parallel Operated Inverters in Islanded Microgrid.
(IIUC Central Library, 2015-05) Mohiuddin, Abdullah al; Mola, Md. Asraful
A microgrid is a part of a distribution network embedding multiple distributed generation systems like photovoltaic panels, small wind turbines etc. and storage systems. This paper focuses on the islanded operation of microgrids. In this mode of operation, the micro-sources are required to operate autonomously to regulate the local grid voltage and frequency. To make voltage and frequency stable, there have several control method in microgrid. The conventional droop control is typically used to achieve this autonomous voltage and frequency regulation. But conventional droop control has real and reactive power sharing limitations. To share the load accurately in proportion to their power ratings two condition should have met. The condition are the droop controllers must have same per unit output impedance and have same voltage set-point for the inverters. But it is difficult to meet in practice. In this paper, the inherent limitations of the conventional droop control scheme are revealed. That’s why robust droop controller is proposed which can share the load accurately without meeting the above conditions. It also help to reduce voltage drop due to load effect and droop effect. The robust works against numerical errors, disturbances, parameter drifts and component mismatches. In simulation part, the output shows the proportional load sharing among inverters.

(IIUC Central Library, 2015-07) MOJUMDER, A.T.M. FAZLE RABBI; BISWAS, KALLOL
This thesis discusses the design of an integrated circuit layout for Bangla Alphabet character. Due to concerns of cost, power loss and design complexity the IC based Bangla Alphabet character display become more popular over the other method. Such as microcontroller based method. There are a little work done on the field of IC based Bangla Alphabet character technology. In this thesis we have tried to propose an IC which is capable to make all the Bangla alphabet character. In order to produce the layout, the basic knowledge of fabrication process and IC design rule are expounded. The complete layout of the IC was designed based on its schematic circuit, diagram which consists of NOT gate, 5-input AND gate, 2-input and 3-input and 5-input OR gate. The layout has undergone design rule checker by MICROWIND. Both layout and schematic circuit of the IC were than simulated through MICROWIND and DSCH to ensure they were identical. The both simulated output of IC should be essentially identical and should match the theoretical results. All Bangla vowel and consonant can be characterized through our proposed IC.

Arduino Mega is used as the brain of this project which controls the full system. A GSM shield is used here to send alert messages in case there occurs any problem on the system or for safety issues. The programming language used in this prototype version is C Language. Finally the system is designed and implemented in its prototype version.
Design a Grid Connected PV Solar System for IIUC Female Academic Building
(IIUC Central Library, 2015-11) Tipu, Md.Ohidul Alam; kanungo, Biswajit
This study aims at developing a standard procedure for the design of a grid connected PV solar system for IIUC campus using rooftops of those building which are favorable to the sunlight and other system is car parks. Bangladesh is facing an acute shortage of energy. Natural gas is the main source of electricity generation in Bangladesh. But the limited gas reserves cannot fulfill the necessities of both domestic requirements and industrial and commercial demands, especially demands for electricity generation for long. Due to this shortage of electricity, not only we are facing load shedding across the country but also the industrial sector is badly affected. Since load shedding occurs, the campus faces so many problems due to absence of continuous power. To ensure continuous power supply, we have chosen solar power as our second way to fed power which will be grid connected. This will be beneficial way to make up the power crisis. A grid-connected photovoltaic power system will reduce the power bill of our campus as it is possible to sell surplus electricity produced to the local electricity supplier. These are comparatively easier to install as they do not require a battery system. Grid interconnection of photovoltaic (PV) power generation systems has the advantage of effective utilization of generated power because there are no storage losses involved. A photovoltaic power system is carbon negative over its lifespan, as any energy produced over and above that to build the panel initially offsets the need for burning fossil fuels. Even though the sun doesn't always shine, any installation gives a reasonably predictable average reduction in carbon consumption.

(IIUC Central Library, 2017-08-18) Nath, Ashim; Ashraf-Ur-Rahman, Muhammad.
An automotive health monitoring system with RF communication for doctor’s chamber has been designed and implemented in this project. Our aim is not only to provide the measured data but also to couple the resultant data with user’s body mass index (BMI) and complete the whole process within a short time so that a doctor can give proper counselling to his patients. The system consists of Arduino Uno, LCD display, RF transmitter and receiver and three peripherals; namely, (1) height sensor (2) weight sensor (3) pulse sensor. Microcontroller ATmega328 which is mounted on Arduino Uno stores the program. All programs are written in C programming language. RF transmitter and RF receiver provide optioning to transmit the measured and calculated data towards doctor’s console. Finally, LCD display shows height, weight, pulse, BMI score and also categorize patient’s health status in accordance with ideal BMI chart. For example, if BMI score of a patient be 23.5 then his health status will be shown as “HEALTHY”; again, if the BMI score be 28 then the health status will be “OVERWEIGHT” and so on. Our proposed device can also be used as self-health manager as it is very user friendly and doesn’t require much space to install. We believe that this system would be a great helping hand to quantify the medical treatment
