A global optimal control methodology and its application to a mobile robot model
(Elsevier B.V., 2016)
A global optimal control algorithm is developed and applied to an omni-directional mobile robot model. The aim is to search and find the most intense signal source among other signal sources in the operation region of the ...
The DAG Project, a 4m class telescope: The telescope main structure performance
(SPIE, 2016)
Dogu Anatolu Gözlemevi (DAG-Eastern Anatolia Observatory) Project is a 4m class optical, near-infrared Telescope and suitable enclosure which will be located at an altitude of 3.170m in Erzurum, Turkey. The DAG telescope ...
Agile development approach for the observatory control software of the DAG 4m telescope
(SPIE, 2016)
Observatory Control Software for the upcoming 4m infrared telescope of DAG (Eastern Anatolian Observatory in Turkish) is in the beginning of its lifecycle. After the process of elicitation-validation of the initial ...
DAG-TGI: Turbulence generator instrument for DAG (Eastern Anatolia Observatory)
(SPIE-Int Soc Optical Engineering, 2018-07-18)
DAG (East Anatolia Observatory) Telescope has 4 m mirror with active optics (a0) and adaptive optics (AO) systems. In order to evaluate DAG's focal plane instruments and their installation, calibration and laboratory ...
In Flange Derotator Design for the 4m DAG telescope
(SPIE-INT Soc Optical Engineering, 2018-07-06)
The field rotation effect can be described as observing the gyration of an object with the pupil of the Eastern Anatolian Observatory (DAG) telescope around the optical axis under the influence of the latitude of the ...
Effect of the computational domain selection on the calculation of axial fan performance
(International Symposium on Transport Phenomena and Dynamics of Rotating Machinery, ISROMAC 2016, 2019)
In this study, the aerodynamic performance of a jet fan (considered as a free-inlet free-outlet axial fan which does not contain any duct at the upstream or downstream) is obtained by using CFD (Computational Fluid Dynamics) ...

Adaptive backstepping approach for 2-DOF telescopes despite unknown wind disturbance
(Institute of Electrical and Electronics Engineers Inc., 2019-07)
Small ground telescopes on the marked are widely used in many space observatories and scientific researches. There are three main problems in such telescopes; positioning of the focal point and the need of tuning for both ...
Computational and asymptotic methods in aeroacoustics with applications
(Işık University Press, 2011)
In this article the computational and asymptotic methods used in aeroacoustics are reviewed. In particular, two different aeroacoustic applications are demonstrated.In the first problem we investigate the first and second ...
Effects of turn-milling conditions on chip formation and surface finish
(Elsevier Science BV, 2019-04-24)
Turn-milling operations performed on mill-turn machines offer significant advantages provided that appropriate conditions are used. Compared to conventional machining processes, kinematics and geometry of turn-milling are ...
