in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...

since the modern art is chosen to discuss, it means a wide expansion of art courses are affected by modernism that enter to the new realms. because of expanded subject, lack of sources and also the close relationship between painting and animation, this thesis emphasizes on the painting and it is recommended to use the phrase “modern painting” instead of modern art (which is more general). thi...
