Accounting for the role of turbulent flow on particle dislodgement via a coupled quadrant analysis of velocity and pressure sequences
(Elsevier Sci LTD, 2017)Recent studies have demonstrated the importance of duration, in addition to magnitude, of energetic turbulent events on particle dislodgement under threshold of motion conditions. It is therefore proposed here that the use ... -
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 ... -
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, ... -
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, ... -
Assessing concrete strength by means of small diameter cores
(Elsevier Sci LTD, 2008)Estimation of concrete strength may be gained from compression tests conducted on cores having a diameter considerably smaller than the recommended one of 100 mm. This paper examines the results of tests applied on the 69 ... -
Basin/Reservoir System Integration for Real Time Reservoir Operation
(Springer, 2016)This paper demonstrates the basin/reservoir system integration as a decision support system for short term operation policy of a multipurpose dam. It is desired to re-evaluate and improve the current operational regulation ... -
Capturing knowledge in construction projects: Knowledge platform for contractors
(Asce-Amer Soc Civil Engineers, 2008)Managing knowledge effectively is critical to the survival and advance of a company, especially in project-based industries such as construction. However, capturing knowledge in construction projects is a tedious task, as ... -
CFD simulations of self-compacting concrete with discrete phase modeling
(Elsevier Sci LTD, 2018)Self-compacting concrete (SCC), is a special type of concrete with high compaction ability in the form-work with its own weight and compacted without any vibration. The main important advantage of SCC is the stability of ... -
Change in maximum isolator displacements due to change in orientation of scaled near field ground motion records
(Gazi University, Fac Engineering Architecture, 2018)In this study, the change in maximum isolator displacements (MIDs) of a seismically isolated structure is studied as a function of ground motion orientation. The isolator units of the analyzed structure is composed of lead ... -
A comparative study on the interpretation of concrete core strength results
(Thomas Telford Publishing, 2006)Cores measuring 94 mm and 144 mm in diameter and having length-to-diameter ratios of 2-0, 1.0 and 0.75 were removed from beam specimens produced from different concrete mixtures. Standard cubes and cylinders were also ... -
Comparison of Spatial Interpolation Methods of Precipitation and Temperature Using Multiple Integration Periods
(Springer, 2018)Eight spatial interpolation methods are used to interpolate precipitation and temperature over several integration periods in a local scale. The methods used are inverse distance weighting (IDW), Thiessen polygons (TP), ... -
Contribution of Built Environment Design Elements to the Sustainability of Urban Renewal Projects: Model Proposal
(Asce-Amer Soc Civil Engineers, 2019)Urban renewal aims to solve the problems caused by unplanned urbanization and urban aging, and it presents a significant opportunity to create sustainable urban areas in Turkey, where a major urban renewal movement was ... -
The current status and future opportunities of hydroelectricity
(Taylor & Francis Inc, 2007)This study presents the status of and prospects for the current state of small hydropower technologies used to produce electricity and assesses their future prospects. The hydropower currently provides about 20% of the ... -
Design Gyration Number Determination of 100mm-Diameter Asphalt Mixtures
(Springer International Publishing Ag, 2019)At present, there is no accepted standard by highway authorities on the compaction procedures of 100mm-diameter gyratory compactor specimens. In previous studies on gyratory compaction, the method of either coring from ... -
Determination of the Optimal Polypropylene Fiber Addition to the Dense Bituminous Mixtures By the Aid of Mechanical and Optical Means
(Vilnius Gediminas Tech University, 2012)Polypropylene fibers are completely native modifiers and they do not have any dependence on abroad in case of technology. When viewed from this point, the modification of bituminous binders with polypropylene fibers is a ... -
Developing a decision support framework for real-time flood management using integrated models
(Wiley, 2018)Flood risk mitigation during real-time flood events comprising snowmelt under hydrological uncertainty is particularly challenging. Giving this due consideration, the aim is to develop a Decision Support System (DSS) for ... -
