Kaya, İbrahim
In this thesis; analysis, design and implementation of a DC-DC converter with active clamp forward topology is presented. The main objective of this thesis is generating a rectified sinusoidal voltage at the output of the converter. This is accomplished by changing the reference signal of the converter. The converter output is applied to an inverter circuit in order to obtain sinusoidal waveform. The zero crossing points of the converter is detected and the inverter drive signals are generated in order to obtain sinusoidal waveform from the output of the converter. Next, the operation of the DC-DC converter and sinusoidal output inverter coupled performance is investigated with resistive and inductive loads to find out how the proposed topology performs. The design is implemented with an experimental set-up and steady state and dynamic performance of the designed power supply is tested. Finally an evaluation of how better performance can be obtained from this kind of arrangement to obtain a sinusoidal output inverted is thoroughly discussed.

Investigation of the significance of periodicity information in speaker identification
Gürsoy, Seçil; Çiloğlu, Tolga; Department of Electrical and Electronics Engineering (2008)
In this thesis; general feature selection methods and especially the use of periodicity and aperiodicity information in speaker verification task is searched. A software system is constructed to obtain periodicity and aperiodicity information from speech. Periodicity and aperiodicity information is obtained by using a 16 channel filterbank and analyzing channel outputs frame by frame according to the pitch of that frame. Pitch value of a frame is also found by using periodicity algorithms. Parzen window (ke...
Intraday markets and potential benefits for Turkey
İlseven, Engin; Sevaioğlu, Osman; Department of Electrical and Electronics Engineering (2014)
In this thesis work; the characteristics, applications, logic, and potential benefits of intraday markets are investigated comprehensively. The properties of intraday markets are examined, and within this framework the applications of intraday markets in Europe and the mechanism that is going to be applied in Turkey are discussed. Also, considering the increasing importance of intraday markets, the logic behind these markets is examined. In this respect, the uncertainties which cause imbalances in the balan...
Robust quality metrics for assessing multimodal data
Konuk, Barış; Akar, Gözde; Department of Electrical and Electronics Engineering (2015)
In this thesis work; a novel, robust, objective, no-reference video quality assessment (VQA) metric, namely Spatio-Temporal Network aware Video Quality Metric (STNVQM), has been proposed for estimating perceived video quality under compression and transmission distortions. STN-VQM uses parameters reflecting the spatiotemporal characteristics of the video such as spatial complexity and motion. STN-VQM also utilizes parameters representing distortions due to compression and transmission such as bit rate and p...
New methods for decentralised sensor fusion and extended target tracking models
Köksal, Hilal; Özkan, Emre; Department of Electrical and Electronics Engineering (2022-12-16)
The focus of this thesis is two-fold; the first study investigates the use of student-t distribution for the decentralised multi-sensor fusion problem. Multi-sensor fusion can suffer from several artefacts such as low channel capacity, delays in the communication channels, the correlation in the acquired information and sensor biases. When combined with these artefacts, the errors in the local sensors’ estimates can result in conflicting information at the fusion center. Such conflicts may later be resolved...
