He was done in Al-Sader educational hospital in maysan Governorate. The robot was manufactured by Karel Storez company. Connecting linkages were increased to get seven degrees of freedom. The optimal performance was obtained by using genetic algorithm method to choose the optimal path planning in the working area, this was done by making an integrated computer program through MATLAB language (R2013a).The results of best path planning would shorten length without hitting any obstacle, assuming the surrounding environment will be variable, the position and obstacle shapes would be random. We found that the best path planning in every environment depends on objective function. The practical side was made in laboratory of the

Trying to satisfy the ideal operation conditions of the solar panel, heat sink was fixated on the back of the PV panel to use as a passive technique. An Analytical thermal model based on the steady state and one dimension analysis condition was built to transfer the excess heat from PV panel with the heat sink existing to predict the operation temperature of PV panel. Theoretical results were compared with experimental results of solar panels cooled by heat sink, in order to validate the suggested thermal model. Also, the effect of the solar cells temperature on the panel performance has been studied experimentally. The results displays that using pin fins array as a cooling technique led to drop in the average panel's temperature nearly 5.9°C and an enhancement of the average output power nearly 13.5%.

The total mass of the amphibious robot is about 24.5 kg. The design of the robot consists of the body which was made from Perspex type transparent and designed in two parts (front and rear parts). The movement of the robot while climbing obstacles is similar to the movement of the cockroach. The robot moves by three pairs of wheel legs, two pairs are named wheel legs-propeller (developed in this paper), each pair work by D.C motor and third pair type wheel legs (move without motor). When swimming in the water, two upper propellers were added at the outer surface of the top of each part of the body and the steering mechanism. The front and rear parts contain, mechanical and e...

The design and construction of an instructional program have done by using analysis design implementation and evaluation (ADDIE) instructional model. It is used for simulation the designing of engineering system using modern and intelligent controller technique. The simulation design was dependent on new methodology is named software cycle method. To achieve the aims from the program a questionnaire is prepared to evaluate the program by a number of experts and beneficiary groups. The result of the questionnaire is used as a feedback process. A development is done to achieve the link between two different techniques. Designing instructional program under windows to be used by designer engineers and students may help to learn the design steps for modern technique and intelligent technique.
