Alternative electricity generation opportunities
(Taylor & Francis Inc, 2008)In this article, comparing four renewable energy sources shows 70% of the electricity generated by the four to come from geothermal with only 42% of the total installed capacity. Wind energy contributes 27% of the electricity, ... -
A new approach to neural trip distribution models: NETDIM
(Taylor & Francis LTD, 2009)This paper develops and presents a new neural network approach to model trip distribution, which is one of the important phases of conventional four-step travel demand modelling. The trip distribution problem has been ... -
Retained properties of concrete exposed to high temperatures: Size effect
(John Wiley & Sons LTD, 2009)Concrete as a construction material is likely exposed to high temperatures during fire. The retained properties of concrete after such exposures are still of great importance in terms of the serviceability of structures. ... -
Accumulated strain prediction of polypropylene modified marshall specimens in repeated creep test using artificial neural networks
(Pergamon-Elsevier Science LTD, 2009)This study presents an application of artificial neural networks (ANN) for the prediction of repeated creep test results for polypropylene (PP) modified asphalt mixtures. Polypropylene fibers are used to modify the bituminous ... -
Repeated Creep Behavior of Polypropylene Fiber-Reinforced Bituminous Mixtures
(Asce-Amer Soc Civil Engineers, 2009)In recent years, research has been devoted to the control of permanent deformations in flexible pavements. In order to prevent rutting, fatigue, and low-temperature cracking, different types of polymer modifiers have been ... -
Obruks, as giant collapse dolines caused by hypogenic karstification in central Anatolia, Turkey: analysis of likely formation processes
(Springer, 2009)Understanding the development of collapse dolines is crucially important because sudden formation of these landforms threatens property and life. Obruks are mega collapse dolines developed in the lacustrine Neogene carbonates ... -
Modelling and forecasting snowmelt runoff process using the HBV model in the eastern part of Turkey
(John Wiley & Sons LTD, 2009)Snowmelt runoff in the mountainous eastern part of Turkey is of great importance as it constitutes 60-70% in volume of the total yearly runoff during spring and early summer months. Therefore, determining the amount and ... -
Prediction of Marshall test results for polypropylene modified dense bituminous mixtures using neural networks
(Pergamon-Elsevier Science LTD, 2010)This study presents an application of neural networks (NN) for the prediction of Marshall test results for polypropylene (PP) modified asphalt mixtures. PP fibers are used to modify the bituminous binder in order to improve ... -
Nonintrusive Method for Detecting Particle Movement Characteristics near Threshold Flow Conditions
(Asce-Amer Soc Civil Engineers, 2010)Bed-load measurements comprise an important component in the development of reliable formulas, in an effort to obtain the necessary constitutive relations between the amount of transported material and flow parameters. The ... -
An investigation of small hydropower potential from multipurpose dams in the Porsuk River Basin
(Sila Science, 2011)In this paper, the small hydropower potentials of the existing multipurpose dams in the Porsuk River Basin were investigated. For this purpose, the Porsuk River Basin was selected as the research area. The objective of the ... -
Analytical Fragility Curves for Ordinary Highway Bridges in Turkey
(Earthquake Engineering Research Inst, 2011)This study focuses on the development of analytical fragility curves for the ordinary highway bridges constructed after the 1990s. Four major bridge classes were employed based on skew angle, number of columns per bent, ... -
An investigation of heavy metal and migration through groundwater from the landfill area of Eskisehir in Turkey
(Springer, 2011)This paper was conducted in order to determine the groundwater and soil pollution within and around the landfill of Eskisehir, Turkey. In this paper, mud, leachate and groundwater samples were collected seasonally a year ... -
Experimental and numerical modal analyses of a historical masonry palace
(Elsevier Sci LTD, 2011)This study presents the determination of modal properties of a historical masonry palace built between 1861 and 1865 in Istanbul. Both an experimental and a numerical study have been performed. The experimental study was ... -
The Value of Snow Depletion Forecasting Methods Towards Operational Snowmelt Runoff Estimation Using MODIS and Numerical Weather Prediction Data
(Springer, 2012)Forecasting streamflow mainly due to snowmelt in the mountainous eastern part of Turkey is important in terms of effective management of water resources at the headwaters of Euphrates River, where large dam reservoirs are ... -
Leaching of trace metals from high carbon fly ash stabilized highway base layers
(Elsevier Science BV, 2012)Fly ash produced by power plants in the United States occasionally contains significant amounts of unburned carbon due to the use of low nitrogen-oxide and sulphur-oxide burners in recent years. This ash cannot be reused ... -
Statistical distributions of in situ microcore concrete strength
