Economic crises and environmental problems increased the necessity of paying attention designing and exploitation problems from power system in military places such as frontier and suburban garrisons. From the other side producing electricity with investing high expense in it is limited , so using from scattered productions increases exploitation from existing electricity capacity and have a very good effect on expenses and investing in electricity demanding and developing in distribution system , by concentrating on the limitation of voltage subsidence and circulation capacity of Feeders , building new Substations and concentrated Power plant in military places such as frontier and suburban garrisons is necessary also there is too much increase in producing electricity by using renewable power sources in all over the world. Scattered producing systems in small sites can solve electricity consumption problems in military garrisons and Centers are in load so if we use renewable scattered production we can decrease producing expenses because in this situation we don’t have any expenses for fuel consumption of scattered productions after the installation of producing system in military places. In this paper we try to have a passing over kinds of scattered productions in distribution network beside Feasibility of using production in military and disciplinary places such as garrison, for decreasing expenses.

At the moment Designing and Constructing power distribution system in the world Just as three phase distribution lines and will be done High costs. If Overhead power Areas such as rural , Police posts and Low population Areas such as The border station saberi Hamoun lake be considered These costs will be significantly a significant increase So that electrification to the fetus, where economic justification And only from the social point with the objective of aids deprivation and necessity, will provides electrification. In this paper Power supply to the border station saberi Hamoun lake of the method ((Single Wire Earth Return)) done. This system because of its low cost relative to the three-phase system can be good economic sense Power supply to be border station saberi Hamoun lake. In this paper, we introduced single Phase Systems SWER and the study of its designing To the operational implementation of the system for Power supply to be border station saberi Hamoun lake paid and The end results will be analyzed and its advantages.

Composite materials are used widely in construction industry. Their resistance to corrosion, stability, lower maintenance cost and other pros compared to other new materials make it promising for further usage. However, utilizing these materials suffers from some challenges such as environmental concerns, being costly and etc. This study compares its advantageous and disadvantageous in construction industry.

Iran due to geographical and political situation of our country are at risk of natural hazards (earthquakes and floods) and man-made threats (war) has been and heavy casualties and property losses incurred. Unfortunately, in our country despite eight years of sacred defense and leaving behind a valuable experience against natural disasters, the importance of safety and security in urban planning and architecture, as it should have been and continue to see and instruments that are increasingly vulnerability in times of crisis increases the physical environment.defense in case of bombing up and restore damaged areas of cost and less time will be possible. Paper aims to address these issues in the field of architecture to the development of civil defense and defense architecture principles among managers and planners and architects and urban designers is defense.

The sense of belonging to a place and mental relaxation is the same as sanity and the power of compatibility with circumference and other people, and the lack of intellectual link with circumference and consequently stress is one of the main factors that disturb this relaxation. Today’s world brings much kind of stresses on people and some of them are among workplace stresses. Workplace is among places that one spends a huge part of his/her time in it. Police stations just like other workplaces are not exception to this. And perhaps it is dealt with in such a way that the staffs experience much more stress while facing with the circumference. The main purpose of this part is to design a structural example of police station according to its effect on clients’ and staffs mental relaxation in each city via a form of sense of belonging to a place. The improvement of structural design via the intellectual link of residents with the place and the area with which he/she has a belonging sense to it, increases the performance of the staffs of police station, leads to their mental relaxation in workplace, the improvement of their relation with clients and also, improvement of the attitude of people to police stations, reinforcement of the relation between people and staffs and their mental and intellectual relaxation whilst referring to police stations.
