Security Dimesion of Turkey's relations with Russia: 2000-2010
Güreş, Gülşah; Tanrısever, Oktay Fırat; Department of Eurasian Studies (2011)
This thesis aims to examine the security dimension of Turkey’s relations with Russia during the period between 2000 and 2010. In this context, political, military and energy aspects of the security relations between Turkey and Russia are examined in detail. Contrary to the views that conceive the recent rapprochement in Turkish-Russian relations as ‘strategic partnership’ or a form of cooperation that has the potential of reaching the level of strategic partnership, the thesis argues that these countries ha...
Pyrolysis and combustion behaviour of various fuels in oxygen-enriched air and CO2 atmospheres
Yüzbaşı, Nur Sena; Selçuk, Nevin; Department of Chemical Engineering (2011)
Oxy-fuel combustion technology, which is based on burning coal in a mixture of oxygen and recycled flue gas (RFG), is suggested as one of new promising technologies for capturing CO2 from power plants. In this thesis study, the pyrolysis and combustion behaviour of various fuels including imported coal, petroleum coke, two different types of indigenous lignites, olive residue and their blends with different proportions in air and oxy-fuel conditions were investigated by using non-isothermal thermogravimetri...
GIS-Based search theory application for search and rescue planning
Söylemez, Emrah; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2007)
Search and Rescue (SAR) operations aim at finding missing objects with minimum time in a determined area. There are fundamentally two problems in these operations. The first problem is assessing highly reliable probability distribution maps, and the second is determining the search pattern that sweeps the area from the air as fast as possible. In this study, geographic information systems (GIS) and multi criteria decision analysis (MCDA) are integrated and a new model is developed based upon Search Theory i...
GIS-based structural performance Assessment of Sakarya City after 1999 Kocaeli-Turkey earthquake from geotechnical and earthquake engineering point of view
Yılmaz, Zeynep; Çetin, Kemal Önder; Department of Civil Engineering (2004)
The August 17, 1999 Kocaeli-Turkey Earthquake (Mw=7.4) caused severe damage to the structures and lifelines in the Marmara region. Soil liquefaction was identified as one of the major causes of this damage. The aim of this study is to determine geotechnical and earthquake engineering factors that contribute to the structural damage observed in Sakarya city after 1999 Kocaeli Earthquake. For this purpose, the results of an extensive field investigation program compiled by General Directorate of Disaster Affa...
Optimal management of coastal aquifers using heuristic algorithms
Demirbaş, Korkut; Altan Sakarya, Ayşe Burcu; Önder, Halil; Department of Civil Engineering (2011)
Excessive pumping in coastal aquifers results in seawater intrusion where optimal and efficient planning is essential. In this study, numerical solution of single potential solution by Strack is combined with genetic algorithm (GA) to find the maximum extraction amount in a coastal aquifer. Seawater intrusion is tracked with the potential value at the extraction well locations. A code is developed by combining GA and a subroutine repeatedly calling MODFLOW as a numerical solver to calculate the potential di...
