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.

Implementation of an Optical Character Reader (OCR) for Bengali language
Chowdhury, Muhammed Tawfiq; Islam, Md. Saiful; Bipul, Baijed Hossain; Rhaman, Md. Khalilur
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.

System design of two wheeler self-balanced vehicle
Rumi, Sheikh Mohibul Islam; Hossain, Mehdi Fakid; Islam, I.S.M. Shanamul; Rahman, Md. Khalilur
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.

Exploring modular architecture for nano satellite and opportunity for developing countries
Rhaman, Md. Khalilur; Monowar, M. I.; Shakil, Shifur Rahman; Kafi, A. H.; Antara, R. S I
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.
