Measurement and assessment of fatigue life of spot-weld joints
(Asme-Amer Soc Mechanical Eng, 2009-01)
Spot-weld joints are commonly used to fasten together metal sheets. Because fatigue fracture is the most critical failure mode for these joints under fluctuating loads, understanding their fatigue failure behavior and ...
TROIA Adaptive optics system for DAG telescope; assembly and laboratory performance prior to on-sky assessment
(SPIE, 2022-08-29)
In this article, we describe the current status of the development of TROIA* a pyramid wavefront sensor based adaptive optics system designed for DAG, a new 4 m telescope located in Eastern Anatolia, Turkey. The wavefront ...

A source seeking algorithm with application to a quadcopter model
(Nova Science Publishers, 2019-01-01)
A novel extremum seeking (ES) algorithm is developed and its performance is tested on a quadcopter type unmanned aerial vehicle (UAV) model. The motivation of the paper is to develop an ES algorithm that results no ...
Eastern Anatolia Observatory (DAG): The status in 2020
(SPIE, 2020)
East Anatolian Observatory's DAG telescope, with its 4m diameter primary mirror and VIS/IR observation capability, will be located on the Konakll-Karaya summit at an altitude of 3170 m, near the city of Erzurum, Turkey. ...
Optical design of the adaptive optics system for DAG, the new 4 m Turkish telescope
(SPIE, 2020)
We present the design of the Adaptive Optics System for the new Turkish 4-m telescope (DAG). The AO will use a pyramid WFS, with a double prism and a no noise EM-CCD camera to allow for oversampling of the pupil images and ...

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 ...
Transient multi-domain thermal modeling of interrupted cutting with coated tools
(Springer Science and Business Media Deutschland GmbH, 2021-09)
Interrupted cutting operations, such as milling, produce fluctuating tool temperatures which directly affect the process outputs. Thus, prediction of cutting tool temperatures enables process planning, selection of materials ...
Effect of scanning strategies and laser parameters on metal-composite joining
(Bellwether Publishing, 2021-07-27)
This study presents an investigation on the effectiveness, automation characteristics, and mechanics of joints between different material types namely glass fiber reinforced plastics (GFRPs) and SS304 stainless steel using ...
