DAG odak düzlemi araçları - hedefler ve seçenekler
(Türk Astronomi Derneği, 2020-12-11)
DAG projesi çerçevesinde, teleskobun da tanımlanması ve optiğinin belirlenmesinden sonra Türk Astronomisinin gereksinim ve gelecek hedefleri de gözetilerek proje ekibi DAG teleskobunun iki Nasmyth odağına yerleştirilecek ...
The effects of atmospheric turbulence on astrophysical observations
(Türk Astronomi Derneği, 2020-12-11)
Atmospheric turbulence is caused by random variations in temperature and pressure that spatially and temporally alter the air’s index of refraction. As electro-magnetic radiation from distant astronomical objects propagates ...
Adaptive optics for DAG telescope
(Türk Astronomi Derneği, 2020-12-11)
What we propose for DAG is therefore a natural guide star GLAO system, that can be turned into a highly efficient AO system. Thus the working principle and expected performance analysis will be shown. In this manner most ...
Observing with DAG: performance metrics of imaging and spectroscopy
(Türk Astronomi Derneği, 2020-12-11)
DAG telescope will be designed as a telescope with adaptive optics and seeing limited modes of observation. Its primary mirror will be a thin meniscus, controlled in shape by an active optics system. This implies specific ...
The DAG project and its management
(Türk Astronomi Derneği, 2020-12-11)
The DAG Project and managerial issues related to call for tenders, determination of technical specifications both for the telescope, the dome and the observatory building will be presented.
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 ...
Modelling and simulation studies on adaptive controller for alt-azimuth telescopes despite unknown wind disturbance and mass
(SAGE Publications, 2020-09-15)
Numerous ground-based observatories are using small sized ground telescopes for scientific research purposes. The telescopes that are available on the market have three main problems. These issues can be listed as: positioning ...
Numerical investigation of the effect of radial lip seal geometry on sealing performance
(IOP Publishing Ltd, 2018)
Sealing elements are often needed in industry and especially in machine design. With the change and development of machine technology from day to day, sealing elements show continuous development and change in parallel ...
Mechanical and thermal modeling of orthogonal turn-milling operation
(Elsevier Science BV, 2017)
Turn-milling is a relatively new machining technology which is performed for cutting of symmetrical or non-symmetrical rotational parts. To improve productivity, determination of cutting parameters in turn-milling is ...
