determination of maximal singularity free zones in the workspace of parallel manipulator

due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...

Vegetation characteristics of four ecological zones of Iran

Environmental (topography, climate) features have an important influence on plant diversity and richness of Iran. Topography is from –28m which is close to Caspian Sea to 5678m which is located on the Alborz Mountain. Two mountains (Alborz and Zagrosss) prevent moist air moving to the centre of Iran. On the basis of environmental factors, four ecological zones with specific plant richness from ...
