Geometry is an important part of mathematics. Described is a Scalable Vector Graphics (SVG) based system for teaching and learning geometry and mathematics. The work is part of the WME project for enhancing mathematics education using Web technologies. An SVG library for diagramming and interactive geometry learning is created. Building on this library, a Web-based authoring tool GeoSVG that ma...

Compared to other parts of the country, region Central Iran still remains mainly outside major tourism flows even though there are significant geosites with great value for geotourism development. Two those sites, Shadow Canyon and Jinns, have excellent qualities development this form in future. The goal research is gain information about preferences Iranian geotourists determine current state ...

the multi-criteria decision making model is an important tool for decision making in water resource management. in this paper, the topsis model was used to rank seven flood management options in the gorganrood river flood management project, including conservation of natural condition, golestan reservoir management, levee construction, diversions-channel construction, flood forecasting and warn...

The assessment of seismic performance of existing structures is becoming an important problem in earthquake engineering. Some important ructures are considerably old and, therefore, their strengths and ductilities are less than strength and ductility demands because of changes in codes and design methodologies. Such structures must be strengthened to resist future earthquakes. First, a structur...
