Modeling and optimization of hybrid electric vehicles
Özden, Burak Şamil; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2013)
The main goal of this thesis study is the optimization of the basic design parameters of hybrid electric vehicle drivetrain components to minimize fuel consumption and emission objectives, together with constraints derived from performance requirements. In order to generate a user friendly and flexible platform to model, select drivetrain components, simulate performance, and optimize parameters of series and parallel hybrid electric vehicles, a MATLAB based graphical user interface is designed. A basic siz...

Hybrid excited synchronous generator design and comparison of direct drive wind turbines
Akgemci, Aysel; Keysan, Ozan; Department of Electrical and Electronics Engineering (2019)
Various types of electrical generators are used in wind turbines and there is not an agreement on the best generator type. Although, high speed Doubly Fed Induction Generators (DFIGs) are still the most common generator topology utilized in wind turbine systems, there is a trends toward direct-drive Permanent Magnet Synchronous Generators (PMSGs), as they are more efficient and reliable. However, permanent magnets (PMs) induce uncontrollable voltage due to the fixed flux resulting from PM excitation. Conven...
Statistical modeling of hourly electricity load series in Turkey
Özpala, Pınar; Gaygısız Lajunen, Esma; Department of Economics (2013)
This study investigates Heterogeneous Double Seasonal ARIMA model, Heterogeneous Periodic AR model and a nonlinear model of Multiple Regime Logistic STAR model by application of hourly electricity load data between years 2006-2007 in Turkey. Forecast results suggest that Heterogeneous Double Seasonal ARIMA model is the best among three methods forecasting up to one day.
Distance-based discretization of parametric signal manifolds
Vural, Elif (2010-06-28)
The characterization of signals and images in manifolds often lead to efficient dimensionality reduction algorithms based on manifold distance computation for analysis or classification tasks. We propose in this paper a method for the discretization of signal manifolds given in a parametric form. We present an iterative algorithm for the selection of samples on the manifold that permits to minimize the average error in the manifold distance computation. Experimental results with image appearance manifolds d...
