DETERMINATION OF SERVICE AREAS BASED ON VECTOR NETWORK MODEL ROADWAYS
Penaz, Tomas; Vojtek, David; Heviankova, Silvie; Kyncl, Miroslav; Duraj, Milos; Yilmaz, Isik; Marschalko, Marian; Drusa, Marian; Orlando, Arencibia Montero; Kubecka, Karel (STEF92 TECHNOLOGY LTD, 2013)The contribution presents the design of an original algorithm for the delimitation of service areas in a vector model of road network. Service areas are derived from the service network, computed for a selected centre on ... -
Differences in the geotechnical properties of two types of gypsum: alabastrine and porphyritic
Yilmaz, Isik (SPRINGER HEIDELBERG, 2007)This study reports an investigation into the physical and mechanical characteristics of fine-grained (alabastrine) and coarse-grained (porphyritic) gypsum from Sivas, Turkey. The geotechnical properties improved as the ... -
Different types of learning algorithms of artificial neural network (ANN) models for prediction of gross calorific value (GCV) of coals
Yilmaz, Isik; Erik, Nazan Yalcin; Kaynar, Oguz (ACADEMIC JOURNALS, 2010)Correlations are very significant from earliest days, in some cases, it is essential as it is difficult to measure the amount directly, and in other cases, it is desirable to ascertain the results with other tests through ... -
The effect of different types of water on the swelling behaviour of expansive clays
Yilmaz, Isik; Marschalko, Marian (SPRINGER HEIDELBERG, 2014)In the design of foundations of structures, especially light buildings, on clayey soils, the main soil behaviours to be considered are swelling properties and surface heave. Therefore, determination of swelling properties ... -
Effect of surface void percentage (SVP) on the unconfined compressive strength (UCS) of porous rocks
Yilmaz, Isik; Yildirim, Mustafa; Marschalko, Marian (GEOLOGICAL SOC PUBL HOUSE, 2018)In this paper, the effect of areal void size on unconfined compressive strength (UCS) depending on the core diameter is investigated and discussed in terms of obtaining more accurate and reliable strength values relating ... -
The effect of swelling clays on a water transport canal between Kokluce HPP and Erbaa HPP (Turkey)
Yilmaz, Isik (SPRINGER HEIDELBERG, 2007)Geological mapping has confirmed the presence of swelling clays in the area of the proposed water transport canal between Korkluce and Erbaa, Turkey. A swelling pressure distribution map was prepared for this part of the ... -
The effect of the sampling strategies on the landslide susceptibility mapping by conditional probability and artificial neural networks
Yilmaz, Isik (SPRINGER, 2010)This study presented herein compares the effect of the sampling strategies by means of landslide inventory on the landslide susceptibility mapping. The conditional probability (CP) and artificial neural networks (ANN) ... -
Evaluation of engineering-geological conditions for conurbation of Ostrava (Czech Republic) within GIS environment
Marschalko, Marian; Bednarik, Martin; Yilmaz, Isik (SPRINGER, 2012)The main aim of the presented study was to create a new type of engineering-geological maps for relative costs for foundation engineering. The newly proposed map in this paper can replace the formerly used maps of the ... -
Evaluation of subsidence due to underground coal mining: an example from the Czech Republic
Marschalko, Marian; Bednarik, Martin; Yilmaz, Isik; Bouchal, Tomas; Kubecka, Karel (SPRINGER HEIDELBERG, 2012)This paper presents a case study dealing with variations on the ground surface due to the underground mining activities in the Ostrava-Karvina Coal District (Czech Republic) over the last 25 years. During this period, some ... -
Forecasting of natural gas consumption with neural network and neuro fuzzy system
Kaynar, Oguz; Yilmaz, Isik; Demirkoparan, Ferhan (SILA SCIENCE, 2011)The prediction of natural gas consumption is crucial for Turkey which follows foreign-dependent policy in point of providing natural gas and whose stock capacity is only 5% of internal total consumption. Prediction accuracy ... -
A fuzzy classification routine for fine-grained soils
Toksoz, Derya; Yilmaz, Isik; Nefeslioglu, Hakan A.; Marschalko, Marian (GEOLOGICAL SOC PUBL HOUSE, 2016)Soil classification is one of the most important stages in preliminary studies for design applications in geotechnical engineering. The classification of fine-grained soils is mostly determined using Casagrande's plasticity ... -
