islamic arts are often identified by their abstract compositions based on geometric principles and spiritual concepts. using artworks from different eras, this paper highlights the presence of a particular model of thought in islamic arts in which the hierarchy of perspectival vision is abolished. the main argument is based on the ability of some artworks to be looked at from any angle while ma...

ParLeda is a software library that provides the basic primitives needed for parallel implementation of computational geometry applications. It can also be used in implementing a parallel application that uses geometric data structures. The parallel model that we use is based on a new heterogeneous parallel model named HBSP, which is based on BSP and is introduced here. ParLeda uses two main lib...

workspace analysis is one of the most important issues in the robotic parallel manipulator design. ‎however, ‎the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...
