On the Use of Conventional and Soft Computing Models for Prediction of Gross Calorific Value (GCV) of Coal
Erik, Nazan Yalcin; Yilmaz, Isik (TAYLOR & FRANCIS INC, 2011)Gross calorific value (GCV) is an important characteristic of coal and organic shale; the determination of GCV, however, is difficult, time-consuming, and expensive and is also a destructive analysis. In this article, the ... -
On the value of dolines in gypsum terrains as a "Geological Heritage": an example from Sivas basin, Turkey
Yilmaz, Isik (SPRINGER, 2012)Karst topography is a landscape shaped by the dissolution of a layer or layers of soluble bedrock, usually limestone and evaporites. Karstification in the Sivas basin (Turkey) has sculpted a beautiful landscape with a ... -
