The recent droughts in Iran made a decline in groundwater table and the migration of villagers to cities was hindered supplying drinking water for the current population. Therefore it should be considered as an important issue. In this regard, it is possible to achieve this goal by constructing underground dams that recently have been suggested to replace by medium and small overland dams. The ...

Faults are the most critical tectonic factors in geological structures, which have major economic impacts on mining economics. Thus it is necessary to understand faults in order to identify the actual risks and complications associated with mining. In the preliminary investigation of the Sonda-Jherruck coalfield, 3D geological modeling was not performed. The purpose of this work was to perform ...

Transmission lines, among the other electrical power system components, suffer from unexpected failures due to various random causes. These failures interrupt the reliability of the operation of the power system. When unpredicted faults occur protective systems are required to prevent the propagation of these faults and safeguard the system against the abnormal operation resulting from them. Th...

â  industrial site selection is a complicated decision and is related to various factors, so it is kind of multi-criteria decision analysis which is used for prioritizing different factors and selecting the best alternative among possible alternatives. in fact by scientific site selection, it is possible to minimize negative impacts of industrial construction and going towards sustainable devel...

Faults are a key problem in software systems. Awareness of possible flaws from the initialization of a project could save money, time and work. Estimating the possible deficiency of software could help in executing software development activities. This paper proposes a model to predict the possibility of faults on a software system before testing. The model predicts possible faults during softw...

The undesired operation of zone 3 may be one of the most conspicuous protective relay features due to the incorrect zone 3 relay operations which have been conducive to the severity of blackouts. Therefore, determining the accurate zone 3 setting of the distance relay is deemed to be necessary. This paper focuses on the development of a new technique for calculating zone-3 setting of distance r...

nowadays urban sanitary landfill compatible with environmental principles and in line with sustainable development is a necessity. in this paper for the purpose of determining appropriate sanitary landfill sites in kohgilooye & boyerahmad province, , many data layers were used including: slope, land cover, distance to main roads, distance to cities & villages, geology, surface water network, di...
