mountains and trees have many similarities. in this way, simorgh of shahnameh shifts from the tree of vispobish to alborz mountain. if simorgh has spiritual existence in avesta, a devilish side has been added to it in shahnameh. in avesta, it lives on a tree, but in shahnameh we find him on alborz mountain. all the researches done on shahnameh and iranian mythology did not pay any attention to ...

Exterior algebraic shifting and symmetric algebraic shifting of bipartite graphs and chordal graphs are studied in the present paper. keywords : Algebraic shifting, chordal graph.

Attention shifting refers to one core component of executive functions, a set of higher-order cognitive processes that predict different aspects of academic achievement. To date, few studies have investigated the role of attention shifting in orthographic competencies during middle childhood and early adolescence. In the present study, 69 first-grade, 121 third-grade, and 85 eighth-grade studen...

In 1925, a game called ‘exquisite corpse’ was invented by a group of surrealists to harness the random power of imagination through collaboration. Working either with words or drawings, an exquisite corpse was begun by one member of the group, who then folded the paper so that his or her contribution was obscured and then passed it to the next member. The game (named after one of their first re...

Phase-shifting interferometry with a genetic algorithm is proposed. The correction of unknown phase-shifting error is an important task in general phase-shifting interferometry. Since phase-shifting errors generate twin image noise in a reconstructed image, we can reduce the phase-shifting errors indirectly by trying to eliminate the twin-image noise in the reconstructed image. By Zernike polyn...
