Properties of light emitting diodes following cobalt-60 irridiation
Özcan, Şafak; Günal, İbrahim; Department of Physics (2004)
The main purpose of this study is to investigate the effects of gamma radiation on the properties of the light emitting diodes. GaP and GaAsP LEDs are used in the study. It is observed that the exposure of a light emitting diode affects its various properties. A cobalt-60 gamma-cell is used to irradiate the selected light emitting diodes. For the different total doses of gamma pre-irradiation and post-irradiation I-V characteristics and spectral responses are recorded. The capacitance characteristics are me...
Assessing impacts of the European framework programme on Turkish participants: a case study on FP6 IST priorty
Metin, Hüseyin; Çilingir, Canan; Erdil, Erkan; Department of Industrial Engineering (2010)
This thesis aims to assess impacts of European Framework Programme for Research and Technological Development (FP) on Turkish participants, focusing on Sixth Framework Programme (FP6) Information Society Technologies (IST) priority. A two-sided approach was employed while assessing impacts. First, DELPHI method was used to quantify and prioritise expectations of the decision makers in key stakeholders; second, a survey was designed to measure additionalities and the level of achievements of program particip...
Preparation of cross-linkedtyrosinase aggregates
Aytar, Burcu Selin; Bakır, Ufuk; Department of Chemical Engineering (2006)
The aim of this study was to prepare cross-linked enzyme aggregate (CLEA) from crude mushroom (Agaricus bisporus) extract. However, the optimization of CLEA production was performed by using pure tyrosinase. Important parameters were determined as protein, ammonium sulfate and glutaraldehyde concentrations, CLEA particle size, and cross-linking temperature and period. On the other hand, the order of ammonium sulfate and glutaraldehyde addition did not affect the yield of CLEA. Optimum CLEA preparation condi...
Extraction of auditory evoked potentials from ongoing eeg
Aydın, Serap; Gençer, Nevzat Güneri; Department of Electrical and Electronics Engineering (2005)
In estimating auditory Evoked Potentials (EPs) from ongoing EEG the number of sweeps should be reduced to decrease the experimental time and to increase the reliability of diagnosis. The rst goal of this study is to demon- strate the use of basic estimation techniques in extracting auditory EPs (AEPs) from small number of sweeps relative to ensemble averaging (EA). For this purpose, three groups of basic estimation techniques are compared to the traditional EA with respect to the signal-to-noise ratio(SNR) ...
Design of smart controllers for hybrid electric vehicles
Özen, Ekin; Dölen, Melik; Department of Mechanical Engineering (2005)
This thesis focuses on the feasibility of designing a commercial hybrid electric vehicle (HEV). In this work, relevant system models are developed for the vehicle including powertrain, braking system, electrical machines and battery. Based on these models ten different HEV configurations are assembled for detailed assessment of fuel consumption. This thesis also proposes a smart power management strategy which could be applied to any kind of HEV configuration. The suggested expert system deals with the exte...
