<p>The present work has the objective of presenting a fixed and solar tracker photovoltaic systems comparative study, through the technical and financial viability evaluation in a public education institution located in the backlands of the state of Paraíba (Brazil). Through a System Advisor Model simulation software, we estimated the electrical energy production of the systems. Then, we performed a statistical analysis to evaluate the differences between the energy production of the proposed systems. Finally, financial indicators were used to assess which system had better financial viability. The results on performance have shown that the annual production of electric energy for photovoltaic systems with tracking is 32% higher than the fixed system. Statistical analysis proved by hypothesis testing that there is evidence that the tracking system produces more electric energy in relation to the fixed system. As for financial evaluation, the fixed system was more advantageous, since its financial indicators were better in all aspects. The research contributed to a better understanding of the differences between photovoltaic systems in terms of technical, financial and statistical aspects, which may help the decision making when choosing the installation of these systems in the region which is being studied.</p>

In this paper two axis sun tracking method is used to absorb maximum power from the sun's rays on the solar panel via calculating the sun’s altitude and azimuth angles, which describe the solar position on the Iraqi capital Baghdad for the hours 6:00, 7:00, 8:00, 9:00, 12:00, 15:00 and 17:00 per day. The angles were calculated in an average approach within one month, so certain values were determined for each month. The daily energy achieved was calculated for the solar tracking method compared with the fixed tracking method. Designed, modeled and simulated a control circuit consisting of reference position truth table, PI Controller and two servomotors that tracked the sun position to adjust the PV panel perpendicular on the rays of the sun. The results obtained by a simulation software MATLAB/Simulink.

There are many people around us who suffer from diseases like paralysis, quadriplegia due to which they cannot move their hands and legs. People suffering from such diseases need a person to be with them all the time to understand their needs and assist them. So, for their aid we want to implement an EYE DIRECTIVE WHEEL CHAIR, which moves in the direction based on the movement of eye balls of the person, helping in mobility. For this project we are designing a system called EYE TRACKING SYSTEM. This system consists of a camera, which is mounted on the wheel chair, which captures the movement of the eye balls of the person continuously. And these images are processed by a simulation software called MATLAB. This directs the motion of the EYE DIRECTIVE WHEEL CHAIR. When the person looks in a direction, the angle of rotation of the eyeball is calculated using MATLAB by processing the images continuously captured by the camera. When the person moves his eye balls in left direction, it shows to move left. Similarly, if he moves his eye balls in right direction, it shows move right. It shows move forward when eye balls or looking straight. And in every other situation it shows stop.

This paper presents the design and development of tracking system for the mines detector robot. The scope for the tracking system covers two important tasks: 1. Design of optimum tracking path to cover maximum scanning area of an enclosed field, and 2. Obstacles avoidance system to be able avoid the various types of obstacles during the scanning process. The tracking algorithms were designed and simulated using Webots simulation software. Upon successful simulation where all design objectives have been achieved, the algorithms were programmed in microcontroller to implement the tracking system on the mines detector robot. Experimental test rig for the robot was a flat surface, enclosed 3m x 3m area where several obstacles of different sizes and shapes were randomly placed. Several metal samples representing the metal detonator of minefield were also placed to test the sensing system of the robot. Infra-red (IR) sensors were used for the system to detect the obstacles and also to detect the end-path boundary of a routine scanning cycle. While simulation test results have shown achieved design objectives, experimental results shown 90% achievement and limitation on evading big size of circle-type obstacle.

Tracking systems of moving objects provide a useful means to better control, manage and secure them. Tracking systems are used in different scales of applications such as indoors, outdoors and even used to track vehicles, ships and air planes moving over the globe. This paper presents the design and implementation of a system for tracking objects moving over a wide geographical area. The system depends on the Global Positioning System (GPS) and Global System for Mobile Communications (GSM) technologies without requiring the Internet service. The implemented system uses the freely available GPS service to determine the position of the moving objects. The tests of the implemented system in different regions and conditions show that the maximum uncertainty in the obtained positions is a circle with radius of about 16 m, which is an acceptable result for tracking the movement of objects in wide and open environments.
