A Phragmen-Lindelof type theorem for quasilinear viscoelasticity equations

Yılmaz, Yalçın; Yılmaz, Yücel (PERGAMON-ELSEVIER SCIENCE LTD, 2007)

We obtained the spatial growth and decay estimates for solutions of a class of quasilinear equations modelling dynamic viscoelasticity in a domain Omega x (0, T), where Omega subset of R-n is a semi-infinite cylinder. (C) ...
Active control of a smart beam with time delay by Legendre wavelets

Yılmaz, Yalçın (ELSEVIER SCIENCE INC, 2012)

Active vibration control in a flexible beam is investigated by taking into account the time-delay which may occur in voltage controlled piezoelectric actuators. The voltage applied to a piezoelectric patch actuator to ...
Decay and growth estimates for solutions of second-order and third-order differential-operator equations

Yılmaz, Yalçın (PERGAMON-ELSEVIER SCIENCE LTD, 2013)

We obtained decay and growth estimates for solutions of second-order and third-order differential-operator equations in a Hilbert space. Applications to initial-boundary value problems for linear and nonlinear non-stationary ...
Finite time blow up of solutions to an inverse problem for a quasilinear parabolic equation with power nonlinearity

Gür, Şevket; Yaman, Metin; Yılmaz, Yalçın (INT SCIENTIFIC RESEARCH PUBLICATIONS, 2016)

We consider an inverse problem for quasilinear parabolic equations with type power nonlinearity. Sufficient conditions on initial data for blow up result are obtained with positive initial energy. Over determination condition ...
Optimal control of a distributed parameter system with applications to beam vibrations using piezoelectric actuators

Yılmaz, Yalçın (PERGAMON-ELSEVIER SCIENCE LTD, 2014)

This paper addresses the issue of the active vibration control of the transverse modes in a flexible elastic systems. The control is implemented by discrete sets of piezoelectric actuators that apply the optimal forces. ...
Spatial estimates for a system of coupled parabolic-hyperbolic equations under nonlinear boundary condition

Yılmaz, Yalçın (PERGAMON-ELSEVIER SCIENCE LTD, 2007)

The aim of this study is to present spatial estimates of Phragmen-Lindelof type for a dynamical system. We show that an appropriate measure of the solutions either tends to infinity by exponential rate or decays to zero ...
