In this paper an algorithm for computing the Balaban and Randic indices of any simple connected graph was introduced. Also these indices were computed for IPR C80 fullerene isomers, Zigzag nanotubes and graphene by GAP program.

It is necessary to generate the automorphism group of a chemical graph in computer-aided structure elucidation. An Euclidean graph associated with a molecule is defined by a weighted graph with adjacency matrix M = [dij], where for i≠j, dij is the Euclidean distance between the nuclei i and j. In this matrix dii can be taken as zero if all the nuclei are equivalent. Otherwise, one may introduce...

Computer-aided process planning has been recognized as an important tool for coordinating the different operations involved in making the product. While temporal knowledge is central to the design of efficient and reliable process plans, little attention is given to the integration of process planning and temporal processing and reasoning. To fill the void, we propose in this paper a practical ...

Biyofilik tasarım, pek çok disiplin tarafından ele alınan yeni, yönlü ve zengin bir yaklaşımdır. Bu disiplinlerden biri de mimarlık olup, insanın doğaya doğada bulunan canlılara karşı hissettiği doğuştan gelen içgüdüsel/duygusal bağın yarattığı yakınlığın mekânsal talepleri biçimlendirmesiyle ilgilenmektedir. Ekoloji sürdürülebilirlik konularıyla ilgili çalışmalara da referans olan biyofilik ya...
