A boiler heating surface is composed of hundreds tubes, whose temperatures may be different because their positions, the influences attempering water, and flue gas. Using a criteria based on Davies–Bouldin index, in this article, we propose to partition into local ones, interactions temperature are represented as weighted graph (HSG) at each point time, current features embedded HSG's nodes. Th...

Kıtasal deformasyonları anlayabilmek ve yorumlayabilmek için farklı yaklaşımlar modeller bulunmakta olup, bunlardan biri de blok modelleme yöntemidir. Blok yardımıyla plaka hareketleri, kayma hızları, faylardaki kilitlenme derinlikleri, Euler kutbu gibi parametreler belirlenebilmektedir. Ancak, sınırları ne kadar iyi belirlenirse, sonuçları o gerçeğe yaklaşmaktadır. modellemenin en önemli adıml...
