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 ...
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 ...
Far-infrared elastic scattering proposal for the Avogadro Project's silicon spheres
(Pergamon-Elsevier Science Ltd, 2018-05)
Avogadro constant determines the number of particles in one mole of a substance, thus relating the molar mass of the substance to the mass of this substance. Avogadro constant is related to Systeme Internationale base units ...
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 ...
Frezeyle tornalamada takımda ortaya çıkan termal deformasyonların modellenmesi
(Gazi Universitesi Muhendislik-Mimarlik, 2017)
Frezeyle tornalama işleminde işlemiş parça doğruluğu ve üretkenliği arttırarak işlem performansını iyileştirmek kesme kuvvetlerini ve takım ucundaki ısı kaynaklı deformasyonları kontrol etmekle mümkündür. Bu çalışmanın ...
A refinement of asymptotic predictions and full numerical solution of helicopter rotor noise in the far field
(Multi-Science Publ Co Ltd, 2012-09-01)
The asymptotic analysis of Parry and Crighton [1] for propeller noise in the far field, which is based on Hanson's formulation [2] of the FW-H equation, is refined to second order by Laplace's method [3] for evaluating ...
