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 ...
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 ...
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 ...

AMOS with EIE as a main subcontractor, was awarded a contract in November 2014 for the design, manufacturing and installation of a 4m-class telescope for the Turkish Eastern Anatolia Observatory (DAG) situated at 3170 m ...
The flexible adaptive optics concept
(Instituto de Astrofisica de Canarias, 2017)
The availability of small deformable mirrors with large number of actuators and stroke, on one hand, and versatile wavefront sensors (pyramid WFS), on the other, allows the development of AO systems whose equivalent pitch ...
Shocks in quasi-one-dimensional bubbly cavitating nozzle flows
(Springer Berlin Heidelberg, 2013-01-01)
Stationary and propagating shock waves in bubbly cavitating flows through quasi-one-dimensional converging-diverging nozzles are considered by employing a homogeneous bubbly liquid flow model, where the nonlinear dynamics ...
