Multistage launch vehicle design with thrust profile and trajectory optimization /
Civek Coşkun, Ezgi; Özgören, Mustafa Kemal; Department of Mechanical Engineering (2014)
In the frame of this thesis, a Matlab® based design tool utilizing a general purpose optimal control solver GPOPS-II® was developed for the optimization of ascent trajectories of multistage launch vehicles. This tool can be utilized both for preliminary mission design of an existing launch vehicle and conceptual design of a new launch vehicle. In the preliminary mission design of an existing launch vehicle, maximizing payload mass is a very common performance measure. Therefore, a trajectory optimization co...
An Approach for System Identification in Unmanned Surface Vehicles
Erunsal, Izzet Kagan; Ahiska, Kenan; Kumru, Murat; Leblebicioğlu, Mehmet Kemal (2017-10-21)
In this study, a system identification methodology is introduced to determine the model parameters of unmanned surface vehicles. The proposed identification scheme is based on sequencing the experiments according to their capabilities to identify the model parameters. In each experiment, the parameters to be found are updated and the results are validated before ascertaining the final value. A procedure to complete the identification work in an experiment, namely the required post-processing, the optimizati...
Evaluation of Feature Channels for Correlation Filter Based Visual Object Tracking in Infrared Spectrum
Gündoğdu, Erhan; SOLMAZ, Berkan; Koç, AYKUT; HAMMOUD, RI; Alatan, Abdullah Aydın (2016-07-01)
Correlation filters for visual object tracking in visible imagery has been well-studied. Most of the correlation-filter-based methods use either raw image intensities or feature maps of gradient orientations or color channels. However, well-known features designed for visible spectrum may not be ideal for infrared object tracking, since infrared and visible spectra have dissimilar characteristics in general. We assess the performance of two state-of-the-art correlation-filter-based object tracking methods o...
Improving the performance of simulated annealing in structural optimization
Hasançebi, Oğuzhan; Saka, Mehmet Polat (2010-03-01)
This study aims at improving the performance of simulated annealing (SA) search technique in real-size structural optimization applications with practical design considerations. It is noted that a standard SA algorithm usually fails to produce acceptable solutions to such problems associated with its poor convergence characteristics and incongruity with theoretical considerations. In the paper novel approaches are developed and incorporated into the standard SA algorithm to eliminate the observed drawbacks ...
Numerical analysis of the effects of atmospheric parameters on space launch center safety
Yaman, İbrahim; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2016)
This thesis study aims at the problem of space launch center safety which is dependent on launch vehicle conceptual design and atmospheric parameters. Selection of the concept at the initial step of the satellite launch vehicle affects the project cost and space launch center safety directly. It is also important to model properties of atmospheric conditions and conduct safety analysis. Successful mission for a launch vehicle depends on providing the total velocity requirement. In this study, launch vehicle...
