Sıcak dövme kalıplarına infrared (kızılötesi) yöntemi ile ön ısıtma uygulanmasına yönelik deneysel ve teorik analiz
(Makina Tasarım ve İmalat Derneği, 2020-09-19)
Sıcak dövme işlemi, üretim teknolojisinin önemli bir parçasınıoluşturur. Sıcak dövmede uygulanan ısı enerjisi ile parçanın akmadayanımı azalır böylelikle şekil verme kabiliyeti artarak daha karmaşıkgeometrili parçaların ...
Jet motorlarinda uygulanan efüzyon film soğutma akış karakteristiklerinin PIV yöntemiyle incelenmesi
(Sürdürülebilir Havacılık Araştırma Derneği, 2018-12-01)
Efüzyon soğutma tekniği, modern yanma odalarında kullanılan en gelişmiş soğutma teknolojisidir. Bu çalışmada 1/9 ölçekte boyutlandırılmış bir yanma odası cidarında, efüzyon film soğutmanın ana akım üzerine etkileri Parçacık ...
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 ...
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 ...
Extremum seeking dead-zone pre-compensator for an industrial control system
(Walter De Gruyter GMBH, 2018-06-26)
PID type industrial controllers such as PI, PD, PID are mature control algorithms and they are intensively used in industry due to their simplicity and easily implementability. However, they start to fail when there is an ...
Investigating effects of milling conditions on cutting temperatures through analytical and experimental methods
(Elsevier Science SA, 2018-12)
Cutting temperatures in milling operations have a significant impact on tool wear, size and shape tolerances and residual stresses of the machined part. Prediction and measurement of cutting temperatures in milling, on the ...
Extremum-seeking control of ABS braking in road vehicles with lateral force improvement
(IEEE-INST Electrical Electronics Engineers Inc, 2014-01)
An ABS control algorithm based on extremum seeking is presented in this brief. The optimum slip ratio between the tire patch and the road is searched online without having to estimate road friction conditions. This is ...
Semianalytical solution of unsteady quasi-one-dimensional cavitating nozzle flows
(Springer, 2014-06)
Unsteady quasi-one-dimensional bubbly cavitating nozzle flows are considered by employing a homogeneous bubbly liquid flow model, where the nonlinear dynamics of cavitating bubbles is described by a modified Rayleigh-Plesset ...
A gain-switched self-optimizer for braking controller
(John Wiley and Sons Ltd, 2017-06)
An emergency braking controller is developed with improved operation characteristics near the maximum friction zone. The methodology is based on self-seeking a-priori unknown optimum operation point to maximize a performance ...
