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 ...
A quasi-one-dimensional bubbly cavitating flow model and comparison with experiments
(European Turbomachinery Soc-Euroturbo, 2011)
A bubbly cavitating flow model is constructed for unsteady quasi-one-dimensional and two-dimensional nozzle flows. In each case, the system of model equations is reduced to evolution equations for the flow velocity and ...
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 ...
A thermo-mechanical model of drill margin-borehole surface interface contact conditions in dry drilling of thick CFRP laminates
(Elsevier Ltd, 2020-04-23)
Dry drilling of thick carbon fiber reinforced polymer (CFRP) laminates requires careful selection of process parameters in order to obtain acceptable borehole surface quality. Complex contact conditions between the drill ...
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) ...
Observatory building design: A case study of DAG with infrastructure and facilities
(SPIE, 2018-07-29)
[No abstract available]
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 ...
Experimental analysis on drilling of Al/Ti/CFRP hybrid composites
(Bellwether Publishing, 2021-01-25)
Carbon fiber reinforced composites (CFRP) have superior mechanical properties such as high strength/density ratio, and good damping ability. CFRP which is frequently used in parts in the aviation industry can also be single ...
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 ...
