Over the course of the last few decades, security systems have undergone radical overhauls and have transitioned into such sophisticated devices that some even completely shun any form of human interventions. In spite of its tremendous innovations, however, such setups have not yet made their way into homes and residences, partly owing to the fact that the equipment bear high price tags and lack user friendliness. This paper propositions a unique security system for residences that aims to solve the shortcomings of commercial alternatives. Basically, a Raspberry Pi 2 System-on-Chip (SoC) computer equipped with a camera module and placed outside the entrance of a house would attempt to identify would-be visitors by the means of image processing and voice identification. The system would spontaneously greet known faces with a friendly voice greeting and unlock the main door to allow them to enter the home. In case of unknown faces, the system would initiate a video call to the home's owner through a smartphone application and allow the owner to communicate with the unknown visitor. Upon receiving approval from the owner, the visitor's details would be entered into the system and the main door would be unlocked. If the owner denies access, he or she has the option to verbally ask the unknown visitor to leave or in extreme cases, press a button to call the police.

Optical Character Recognition (OCR) is the process of extracting text from an image. The main purpose of an OCR is to make editable documents from existing paper documents or image files. Significant number of algorithms is required to develop an OCR and basically it works in two phases such as character and word detection. In case of a more sophisticated approach, an OCR also works on sentence detection to preserve a document's structure. It has been found that researchers put lots of efforts for developing a Bengali OCR but none of them is completely error free. To take this issue in consideration, the latest 3.03 version of Tesseract OCR engine for Windows operating system is used to develop an OCR for Bengali language. Moreover, 18110 characters and 2617 words are used to make the OCR's library. In this research, 'Solaimanlipi' font and 200 input files are used to test the accuracy of OCR. It is found that for clean image files, the accuracy of the software is as high as 97.56%. It is to be noted that accuracy is measured as the percentage of correct characters and words.

Any two wheeler vehicles usually cannot balance by itself when it is in rest or running at a lower speed. The purpose of this research is to make a vehicle that would be stable by itself in such situations and can be stabilized against any physical impact. Two heavy rotating disks with hub motors have been used here to develop the mechanism of compensating the tilt of the vehicle and get it stabilized. To measure the tilt angle, an android device has been used and then the angle of tilt has sent to a Bluetooth receiver which is connected with the vehicle. An android application has been developed which takes the tilt angle as input from its gyroscope and sends data to that receiver accordingly. This arduino controls the motor which has been used to control the tilt direction of both of the rotating disks according to the signal. This vehicle is designed to provide the safety that two wheeler vehicle does not have during an impact or at zero velocity. Hence, this research is aimed to design a safe, cost effective and fuel efficient self-balanced vehicle for third world countries like Bangladesh.

SPACE Technology has the potential to provide information, infrastructure and inspiration that meets national needs in developing countries like Bangladesh. Many countries recognize this; in response they are investing in new national satellite programs to harness satellite services. Technology related to space is one example of a tool that can contribute to development both by addressing societal challenges and by advancing a nation's technological capability. To cope up with the advanced world in space technology Bangladesh seems to be highly potential country for satellite, Robotics, embedded systems and renewable energy research. BRAC University, Bangladesh is planning to launch a nano satellite with the collaboration of KIT, Japan. The proposed nano satellite project mission is to experiment about social, commercial and agricultural survey needs in Bangladesh. Each of the proposed applications of the project will improve the lives of millions of people of Bangladesh and it will be a pathfinder mission for the people of this country. Another intention of this project is to create a cheap satellite based remote sensing for developing countries as the idea of large space systems is very costly for us therefore we have decided to make a Nano-satellite.

In industries loading and unloading of heavy loads manually is one of the most important task which turns out to be quite difficult, time-consuming and risky for humans. This paper illustrates the mechanical design of the industry based automated robot which include: Ackerman Steering Mechanism and Differential Mechanism. Ackerman Steering allows front two wheels to turn left and right in the track without going out of the track. Differential has been mounted with two back wheels and a DC motor has been used with its controller to start motion of the robot. The autonomous robot is designed to start its movement from a starting position where goods are loaded on it, then follow a path of white line drawn on black surface and unload goods by itself after reaching a destination place. Digital Line Following sensor has been mounted in front of the robot so that the sensor can detect path by emitting and receiving signals allowing it to move in the pre-defined track having left and right turns while carrying goods from starting position to the destination. The main objective is to load and unload heavy goods that has been achieved by two large linear actuators for producing required torque and force necessary to unload heavy loads up to 150kg sideways to the ground safely. Besides, the robot has been built up having the ability to avoid collision with any obstacles that come in its way. Building an industrial robot with moderate speed, good efficiency for loading and unloading purpose within a short time to ease human suffering has been the main focus of this paper.

This paper highlights an approach to combat the ramifications of both natural and man-made catastrophe in perspective of Bangladesh, a country highly susceptible to disasters. The aim of the paper is to develop a 'Rescue Robot' that inherits cognitive framework for life detection through rubble. Bangladesh is a developing country, and the purpose of the project is to construct the country's very own rescue machine that can crawl through debris of earthquake and landslides and maintain signal strength using boosters at minimum cost. The robot also has an audio/video monitoring ability with the aid of a digital camera with an adjacent LED torch. The motion of the vehicle is remotely controlled and communication is done through the use of Wi-Fi beacons. This robot can provide a simpler, more reliable and cheaper way to traverse in all types of terrain and locate victims using carbon dioxide sensor.

This four wheel drive robot consists of a bucket-ladder system for excavation and is capable of collecting 8kg of regolith per minutes. It also includes a collector bucket which can contain 18kg regolith and deposit in a bin which is installed on 50 cm height. The excavation hardware can be operated both manually and remotely through a web browser by logging in from any computer without direct visual and auditory access to the hardware. A KINECT sensor based semi-auto navigation is incorporated to avoid obstacle while motion.
A rule based approach for implementation of bangla to english translation
(© 2012 IEEE, 2013) Rahman, Md. Khalilur; Tarannum, Narzu; Department of Computer Science and Engineering
An initiative to model a Bangla to English (B2E) translation using Natural Language Processing (NLP) was proposed in our previous research. Here we implemented the model with a lot of modifications. A very successful translator is observed in Anubadok Online which is based on Penn Treebank annotation system and it can only translate English sentences to Bangla. Penn Tree Bank is the collection of English corpus, so Bangle linguistic processing is not observed there. Bangla is an Irregular Language. In our previous research, we proposed a case structure analysis for verb. There are a lot of influences of case in Bangla language. The relationship between verb and case elements is an important issue for Bangla language. But in our current implementation we used rule based approach. For Bangla-English translation first we performed morphological analysis for Bangla then we used rule based analysis where we considered a limited feature of case analysis. After that, using a dictionary we translate bangle words into English. To make an English sentence, we considered English SVO grammatical rules. Our current system is successfully implemented for the translation of Assertive-Affirmative, Negative and Interrogative sentences.

(© 2014 IEEE Computer Society, 2014-05) Chowdhury, Pritom; Shakim, S. S. Kibria; Karim, Md. Risul; Rhaman, Md. Khalilur; Department of Computer Science and Engineering
Brain Computer Interface (BCI) has opened a new era in the field of neuroscience. It has the potentiality to improve the quality of life of severely disabled patients. It allows them to regain the power of moving things by their affective, cognitive and expressive brain activities. Emotiv EPOC head set is a safe and comfortable BCI system which contains a number of advanced electrode sensors. It can detect and process the user's thoughts, feelings and expressions in real time. A prototype of two wheeler robot is implemented and experimented which was controlled by the thought of human being. In average 72.65% accuracy is observed in the experiment for different aged people from 14 to 30 years old where the accuracy for the physically challenged people is 82% in average. Firstly the prototype software has to be trained by a specific user then it controls a wireless robot by the person's thought for driving the robot in forward, backward, left and right directions. This robot can be stopped by a specific facial expression which does not need any training. The article also investigated the shortcomings and reviews on the reliability of the cognitive output efficiency of Emotiv EPOC EEG device, based on user comments and related researches.
Digitization of the entire traffic system and mitigation of the ongoing traffic crisis across cities of developing nations
(© 2015 Institute of Electrical and Electronics Engineers Inc., 2016-01) Yasar, Mohammad Samin; Rashid, Tahmid; Rhaman, Khalilur; Department of Computer Science and Engineering
This paper focuses on a novel approach for handling the present traffic situation in perspective of Bangladesh. The initial plan is to moderate the ongoing traffic predicament that currently plagues Dhaka city and gradually expand it across cities of neighboring countries. The aim of the paper is to develop a solution to counter the traffic clogging. The approach taken during the course of this research focused primarily on an experimental evaluation of the small-scale model of the traffic routing algorithms. The approach is to develop a traffic algorithm to calculate the routes with shortest possible times to destinations. We plan to implement the system's usability by providing feedback to our target users (car drivers) so that they can decide on which route to take. This will be done by means of an overhead display on the car dashboards backed up by an embedded OS or Android. For our input we plan to take the amount of cars that are at any specific route at a time and provide that data to the car driver by the means of modern vehicle density measurement techniques. In this work, Floating Car Data (FCD) is chosen as the mode of counting vehicle volumes generating vehicle volume indices indicative of traffic jam conditions. Travelling times are calculated using Dijkstra's algorithm and the shortest possible time required is provided to the commuters taking into consideration the situation of the roads at any point of time. The results are then verified in a road traffic simulation software for reliability.

Every machine has a safe range of operation which includes heat emission, produced sound and vibration which an expert technician can troubleshoot most of the problems just by observing the behavior (sound, vibration, smoke, heat emission etc.) of a machine. But the complex machine operation has a hazardous environment which eventually may cause permanent health damage. Depending upon the machine's purpose burns, electric shocks and limb amputations are also possible. In case of a machine has not been maintained properly, it may malfunction and cause injury to either the operator or other personnel on the ground or in the vicinity. To reduce these problems we are developing a special type of monitoring system which will allow us to supervise the condition of machine in real time from a safe distance thoroughly with a full control over it.
Development and feasibility evaluation of a low cost smart voyage data recorder: marine black box
(© 2015 Institute of Electrical and Electronics Engineers Inc., 2016) Abir, Imtiaz Kalam; Rashid, Md. Tahmid; Zaman, Hamid; Hassan, Moontasir; Rafique, Rumana; Rhaman, Md. Khalilur; Department of Computer Science and Engineering
Dating from the dawn of water transportation, marine accidents have been major causes of concern for governments of nations regardless of being developed, developing or underdeveloped. Recalling the recent ferry sinking incidents in Bangladesh, a research was undertaken to develop a smart but yet low cost voyage data recorder namely Marine Black Box. Though it can never be guaranteed that marine accidents would not happen at all, this solution would help to provide an early warning before the onset of a total disaster and even in the scenario when there is indeed no chance to save the vessel, this system would provide a mean to analyze and investigate the true cause of the accident so that future accidents can be avoided or the perpetrators can be accounted for. What makes this Marine Black Box distinct from typical voyage data recorders is that it sends a vessel's number of passengers onboard, temperature, pressure and humidity along with GPS positional data in realtime to a centralized server which can be accessed through a smartphone app. In case when this real-time logging fails, data can still be retrieved from the SD card inside the black box where data is being constantly logged for redundancy. This paper discusses the details of the working principles, construction and practical evaluation of the system.

The basis of this project is to create an electrical pole climbing robot which can be used to reduce the risk of an electrician to connect the distribution lines for supplying purposes. Pole climbing robot, nowadays, is a very common and interesting idea, which mainly works by connecting the distribution lines according to the directions given to it. In this modern era robots are being developed for various purposes to accomplish many tasks which seem to be too complex and life endangering for humans. Benefits of using robots have been immense in terms of risk-free, speed and efficiency of doing required tasks compared to that of humans. The main objective of this work is to to save human lives as numbers of people are died from electrical injuries almost every year in Bangladesh. Considering on that issue, a pole climbing robot has been designed, built and simulated. However, further modifications of this work might be able to perform the wiring and repairing tasks instead of an electrician. The developed robot works on the principle of linear motor, which is partially autonomous. With the installation of this project, risk of human injuries and death can be minimized while working in the distribution lines which is the main consideration of this paper.

A new multilevel solar panel system for urban areas
(© 2013 Institute of Electrical and Electronics Engineers Inc., 2013) Zenan, Ahmed Hosne; Ahmed, Sanjana; Rhaman, Md. Khalilur; Rahman, Mosaddequr Abdur; Department of Computer Science and Engineering
A new multilevel solar panel system is proposed for its use in urban residential solar home systems. The proposed system consists of three panels mounted in a rack one above another at a fixed distance from each other to minimize the floor area while shifted horizontally from each other by half the panel width to avoid shading of the lower panels. In the proposed system, the panels will be fitted with a tracking system to track the sun to maximize the energy collection. Further, a gliding mechanism is perceived for the panels that will enable the panels glide both ways and realign as the sun moves from east to west to avoid shading. Initial calculation, done for March 21st, shows that the proposed multilevel three panel system can harness 18.6% more energy than the three conventional fixed panel systems with 33% less area. The proposed system will be useful for large urban city dwellers, especially in third world countries, where not only electricity is in short supply, availability of roof top space to install solar panels is also very limited.
