Abstract : Generally, blind people use a traditional cane (known as white cane) for moving from one place to other. Although, white cane isthe international symbol of blindness, it could not help them to detect place and to avoid obstacles. In this paper, we represent  a model of walking stick for blind people. It consists of GPS module, GPS Antenna, Arduino, IR sensor and buzzer. This stick can detect place and obstacles. Position detection part is done with GPS module and GPS antenna. IR sensor is used for detecting obstacles. Here, the buzzer produces two types of sound. When the blind reaches to his destination, buzzer buzzes continuously. When the blind faces any obstacles, buzzer buzzes discontinuously. By hearing this two types of sound, blind can be confirmed about his destination and also can avoid obstacles in front of him. The whole system is designed to be small, light and is used in conjunction with the white cane so that it could ensure safety of the blind.

Abstract: Submarine is used to investigate under water. Now a day, with the advancement of technology it is used not only investigation but also to battle and mining operation. Sometimes there are some problems throughout the rivers in our country. Many peoples are lost their lives because of drowning of boat or water vehicle. Therefore, a submarine is designed to solve this problem by investigation underwater. Water and propeller driven by gear motor are used for driving the submarine. It is derived on the principle of jet propulsion. Water is sucked by a propeller which is derived by a pump motor. Then the water passes through the nozzle. Whole system is controlled by microcontroller. Moreover, the system is controlled with the help of remote control. The power which is used to drive motor can amalgamate a percentage from absorbing tidal waves. This design is done perfectly to reduce drag force. Therefore it is an effective design.

Keywords: Submarine, drag force, propeller, jet, propulsion, design, water, microcontroller, remote control.

Abstract: Matured biogas production technology has led to the development of a number of biogas appliances used for lighting, electricity and cooking. The most hopeful among them is the biogas stove, to achieve the energy necessity for cooking application at domestic as well as at the community level. In this research work an attempt has been made to design biogas stove used for Injera baking. This stove was designed by covering the flame under an insulated material. The new gas burner also designed based on: the demand of energy needed during baking and the amount of gas supplied from the biogas plant. This new designed gas burner is used to supply pressure equally on the holes of the burner port. Heat transfer analysis between burner and mitad by radiation, convection heat transfer between flame and wall and heat flow through insulation also determined.

Abstract:This paper basically emphasizes on different methodologies that have been proposed from past few years on object detection. Research on detection has widely covered applications such as artificial intelligence, robotics, security surveillance, identification, face recognition, detection of vehicles in traffic and many more .These applications led to untiring efforts for further techniques yet to be proposed. This paper enlightens us about numerous techniques that have extensively being used for detection in videos.

Keywords:Background subtraction, adaptive means filtering, adaptive median filtering, Eigen backgrounds, simple Gaussian method, Mixture of Gaussian.
