Thermal characterization and kinetics of crude oils by tga and dsc methods
Gündoğar, Satı Aslı; Kök, Mustafa Verşan; Department of Petroleum and Natural Gas Engineering (2010)
In recent years, the application of thermal analysis to study the combustion and pyrolysis behavior of fossil fuels has gained a wide acceptance because of its significance for industry and economy. In this thesis, the thermal and kinetic analysis of different origin crude oil samples are performed by two well-known thermal analysis techniques: Differential Scanning Calorimetry (DSC) and Thermogravimetry (TG/DTG). The investigation of combustion and pyrolysis behaviors, kinetic analysis of oil samples and t...
Strength assesment of Turkish cements
Kul Gül, Nazlı İpek; Yaman, İsmail Özgür; Akkaya, Ayşen; Department of Cement Engineering (2015)
Cement, a hydraulic binder material, is the most important of building materials. The compressive strength test method is used to determine the quality of cement. The cement manufacturers are obliged to carry the CE Marking in accordance with the EN 197 standards for cement production in Europe and Turkey and in accordance with the Building Materials Regulation (CPR). Within the scope of CE Marking, the product certification body performs sampling from the factory in specified periods. The samples obtained ...
Silicon nanostructures for electro-optical and photovoltaic applications
Kulakcı, Mustafa; Turan, Raşit; Department of Physics (2012)
Recently extensive efforts have been spent in order to achieve all silicon based photonic devices exploiting the efficient light emission from nanostructured silicon systems. In this thesis, silicon based nanostructures have been investigated for electro-optical and photovoltaic applications. The thesis focused on three application areas of silicon nanostructures: Light emitting diode (LED), light modulation using quantum confined Stark effect (QCSE) and photovoltaic applications. In the context of LED appl...
Utilization of GGBFS blended cement pastes in well cementing
Alp, Barış; Yaman, İsmail Özgür; Akın, Serhat; Department of Cement Engineering (2012)
In well cementing, the cement slurry is exposed to the conditions far different than those of ordinary Portland cement (PC) used in construction. After placement, hardened cement paste should preserve integrity and provide zonal isolation through the life of the well. American Petroleum Institute (API) Class G cement is the most common cement type used in various well conditions. Class G cement has a high degree of sulfate resistance which makes it more stable than PC when subjected to the compulsive well c...
Local search versus Path Relinking in metaheuristics: Redesigning Meta-RaPS with application to the multidimensional knapsack problem
Arin, Arif; Rabadi, Ghaith (Elsevier BV, 2016-09-01)
Most heuristics for discrete optimization problems consist of two phases: a greedy-based construction phase followed by an improvement (local search) phase. Although the best solutions are usually generated after the improvement phase, there is usually a high computational cost for employing a local search algorithm. This paper seeks another alternative to reduce the computational burden of a local search while keeping solution quality by embedding intelligence in metaheuristics. A modified version of Path ...
