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.
The investigation of the effect of saturation flow on the average vehicle delay at signalized intersections
(Izmir Democracy University, 2021-12-18)
Saturation flow (s) is one of the most important parameters used for determining of signal timings at signalized intersections. Therefore, this parameter directly affects the various intersection performance criteria such ...
TROIA adaptive optics system for DAG Telescope
(SPIE, 2020-12-13)
This paper presents the specifications of TROIA-TuRkish adaptive Optics system for Infrared Astronomy system, the science rationale for these specifications, and description of the site technical and environmental conditions ...
Channel modelling for indoor visible light communications
(Royal Society Publishing, 2020-04-17)
Visible light communication (VLC) allows the dual use of light-emitting diodes (LEDs) for wireless communication purposes in addition to their primary purpose of illumination. As in any other communication system, realistic ...
Improving age of information in random access channels
(Institute of Electrical and Electronics Engineers Inc., 2020-07)
We study Age of Information (AoI) in a random access channel where a number of devices try to send status updates over a common medium. Assuming a time-slotted scenario where multiple transmissions result in collision, we ...
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 ...
