Güvenliğin açmazları: Suriye ve Afganistan deneyimlerinde güvenlik-demokrasi ve güvenlik-istikrar ikilemleri
(Tübitak, 2007)
Güvenlik kavramı gerek siyaset bilimi gerekse uluslararası ilişkiler için temel bir kavram olagelmiştir. Soğuk Savaş yıllarında, tüm uluslararası ilişkiler disiplinini güvenlik çalışmalarının düzlemi olarak görmek gibi bir ...
Circuit models with mixed lumped and distributed elements for passive one-port devices
(Işık Üniversitesi, 2006-01-23)
In this thesis, to model measured data obtained from an actual passive one-port device, a circuit modeling method with mixed lumped and distributed elements is proposed. Namely, measured data is modelled by means of its ...
New approaches for channel estimation in wireless communications
(Işık Üniversitesi, 2006-03-10)
This thesis first proposes a conputationally efficient, pilot-aided linear minimum mean square error (MMSE) batch channel estimation algorthm for the orthogonal frequency division multiplexing OFDM systems in unkonown ...
A sequential Monte Carlo method for blind phase noise estimation and data detection
(IEEE, 2005)
In this paper, a computationally efficient algorithm is presented for blind phase noise estimation and data detection jointly, based on a sequential Monte Carlo method. The basic idea is to treat the transmitted symbols ...
A new coding method for speech and audio signals
(IEEE, 2005)
In this paper a new representation or modeling method of speech signals is introduced. The proposed method is based on the generation of the so-called Predefined Signature S={S R } and Envelope vector E={E K } Sets (PSEVS). ...
A miniature real-time volumetric ultrasound imaging system
(SPIE-Int Soc Optical Engineering, 2005)
Progress made in the development of a miniature real-time volumetric ultrasound imaging system is presented. This system is targeted for use in a 5-mm endoscopic channel and will provide real-time, 30-mm deep, volumetric ...
On some nonlinear waves in fluid-filled viscoelastic tubes: Weakly dispersive case
(2005-06)
By employing the nonlinear equations of motion of an incompressible, isotropic and prestressed thin viscoelastic tube and the approximate equations of an incompressible inviscid fluid, we studied the existence of some ...
Determination of pre-gelation and post-gelation activation energies during free radical crosslinking copolymerization
(Taylor & Francis Ltd, 2005)
Steady-state fluorescence (SSF) and dilatoraetric techniques were used to study the free-radical crosslinking copolymerization (FCC) of styrene (S) and divinylbenzene (DVB) in bulk. The gel points (t g) were recorded by ...
Dissolution of Al2O3-polystyrene latex composites: A fluorescence study
(Taylor & Francis Ltd, 2005)
This work reports the use of the steady state fluorescence (SSF) technique to study dissolution of a composite film formed from a mixture of Al 2O3 and polystyrene (PS) latex particles. The composite films were cast from ...
Higher order approximations in reductive perturbation method: Strongly dispersive waves
(2005-08)
Contribution of higher order terms in the perturbation expansion for the strongly dispersive ion-plasma waves is examined through the use of modified reductive perturbation method developed early by us. It is shown that ...
