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 ...
Extremum seeking control of uncertain systems
(Işık University Press, 2017)
Extremum seeking is used in control problems where the reference trajectory or reference set point of the system is not known but it is searched in real time in order to maximize or minimize a performance function representing ...
A cooperative neural network control structure and its application for systems having dead-zone nonlinearities
(Springer International Publishing Ag, 2022-03)
An adaptive control structure utilizing two feed-forward neural networks (NN) is proposed to deal with systems having unknown nonlinearities. One of the networks is trained to mimic the nonlinear system dynamics. Its ...
Design of a global extremum seeking algorithm for an omni-directional robot model
(Romanian Soc Control Tech Informatics, 2017-06)
A global extremum seeking algorithm is developed for a mobile robot model where the aim is to find the location of the most powerful signal source among the others. In other words, the control problem is to seek the global ...
An emergency braking controller based on extremum seeking with experimental implementation
(Springer Berlin Heidelberg, 2018-03-01)
An extremum seeking scheme is developed for maximizing the longitudinal tire forces of the road vehicles during emergency braking situations. If the road condition is known, then a conventional braking controller could ...
