Accurate solutions of scattering problems involving lowcontrast dielectric objects with surface integral equations
(2007)We present the stabilization of the surface integral equations for accurate solutions of scattering problems involving lowcontrast dielectric objects. Unlike volume formulations, conventional surface formulations fail to ... 
Analysis and design of switching and fuzzy systems
(Bilkent University, 200209)In this thesis we consider the controller design problems for switching and fuzzy systems. In switching systems, the system dynamics and/or control input take dierent forms in different parts of the underlying state space. ... 
Catstate generation and stabilization for a nuclear spin through electric quadrupole interaction
(American Physical Society, 2017)Spin cat states are superpositions of two or more coherent spin states (CSSs) that are distinctly separated over the Bloch sphere. Additionally, the nuclei with angular momenta greater than 1/2 possess a quadrupolar charge ... 
Decentralized strong stabilization problem
(American Automatic Control Council, 1992)In the decentralized strong stabilization problem for linear timeinvariant finitedimensional systems, the objective is to stabilize a given plant using a stable decentralized controller. A solvability condition for this ... 
Dynamic output feedback stabilization of switched linear systems with delay via a trajectory based approach
(Elsevier, 2018)A new technique is proposed to construct observers and to achieve output feedback stabilization of a class of continuoustime switched linear systems with a timevarying delay in the output. The delay is a piecewise ... 
Encapsulation of vanillin/cyclodextrin inclusion complex in electrospun polyvinyl alcohol (PVA) nanowebs: prolonged shelflife and high temperature stability of vanillin
(201208)We produced functional nanowebs, containing vanillin, having prolonged shelflife and high temperature stability facilitated by cyclodextrin (CD) inclusion complexation. Polyvinyl alcohol (PVA) nanowebs incorporating ... 
An Evaluation of the Turkish stabilization and liberalization policies since 1980, in the light of Southern Cone experience
(Bilkent University, 1989)Purpose of this study is to compare the stabilization and liberalization policies implemented in the Southern Cone countries and Turkey. It investigates these policies in a comparative way, and evaluates the Turkish ... 
Finite time estimation through a continuousdiscrete observer
(John Wiley and Sons, 2018)We study two broad classes of nonlinear timevarying continuoustime systems with outputs. For the first class, we build an observer in the case where a state dependent disturbance affects the linear approximation. When ... 
Fixed order controller design via parametric methods
(Bilkent University, 2003)In this thesis, the problem of parameterizing stabilizing fixedorder controllers for linear timeinvariant singleinput singleoutput systems is studied. Using a generalization of the HermiteBiehler theorem, a new ... 
Further stability results for a generalization of delayed feedback control
(Springer, 20120801)In this paper, we consider the stabilization of unstable periodic orbits for onedimensional and discrete time chaotic systems. Various control schemes for this problem are available and we consider a recent generalization ... 
Global stabilization via local stabilizing actions
(Institute of Electrical and Electronics Engineers, 2006)Stabilization of a linear, timeinvariant system via stabilization of its main diagonal subsytems is the underlying problem in all diagonal dominance techniques for decentralized control. In these techniques as well as all ... 
High energy dissipative raman soliton laser through XPM stabilization
(Optical Society of America (OSA), 2015)Dispersion, nonlinearity and gain determine the intracavity pulse behaviour. We show that pump depletion and XPM play a significant role in the stabilization of high energy dissipative Raman solitons. Using this theoretical ... 
Local convex directions
(Institute of Electrical and Electronics Engineers Inc., 2001)A proof of a strengthened version of the phase growth condition for Hurwitz stable polynomials is given. Based on this result, a necessary and sufficient condition for a polynomial p(s) to be a local convex direction for ... 
Magnetic resonance electrical impedance tomography (MREIT) based on the solution of the convection equation using FEM with stabilization
(Institute of Physics Publishing, 20120727)Most algorithms for magnetic resonance electrical impedance tomography (MREIT) concentrate on reconstructing the internal conductivity distribution of a conductive object from the Laplacian of only one component of the ... 
Monoid actions, their categorification and applications
(Bilkent University, 201701)We study actions of monoids and monoidal categories, and their relations with (co)homology theories. We start by discussing actions of monoids via biactions. We show that there is a welldefined functorial reverse action ... 
Multidomain short peptide molecules for in situ synthesis and biofunctionalization of gold nanoparticles for integrintargeted cell uptake
(American Chemical Society, 2015)We describe design and synthesis model of multidomain (modular) peptides (MDPs), which direct a reaction cascade coupling the synthesis and surface functionalization of gold nanoparticles (AuNPs) in a single step. The ... 
Neoliberal global remedies: From speculativeled growth to IMFled crisis in Turkey
(2006)Turkey experienced a severe economic and political crisis in November 2000, and again in February 2001. The IMF has been involved with the macro management of the Turkish economy both prior to and after the crisis, and ... 
A new method for the computation of all stabilizing controllers of a given order
(Taylor & Francis, 2005)A new method is given for computing the set of all stabilizing controllers of a given order for linear, time invariant, scalar plants. The method is based on a generalized HermiteBiehler theorem and the successive application ...
