Graphs with given degree sequence and maximal spectral radius
(Electronic Journal of Combinatorics, 2008-09-15)
We describe the structure of those graphs that have largest spectral radius in the class of all connected graphs with a given degree sequence. We show that in such a graph the degree sequence is non-increasing with respect ...
Bifurcation of drift shells near the dayside magnetopause
(Amer Geophysical Union, 2007-07-10)
Close to the dayside magnetopause, there is a region of space where each field line has two magnetic field minima, one near each cusp. That region is located around local noon, and extends about 1-2 R-e from the magnetopause. ...
Luminescence ages of feldspar contaminated quartz from fluvial terrace sediments
(Wind-J Wojewoda Publ Co, 2008-01-01)
This study focuses on obtaining luminescence ages in feldspar contaminated quartz from well-developed fluvial terraces of the Yesilirmak (Iris) river located inside the eastern North Anatolian Fault Shear Zone (NAFZ). We ...
On the Origin and Age of the Ariburnu Beachrock, Gelibolu Peninsula, Turkey
(Scientific Technical Research Council Turkey-TUBITAK, 2008-03-13)
The beachrock formation on the Ariburnu coast situated in the Gelibolu Peninsula has been studied by field observation, thin-section interpretation, physicochemical analyses including ICP-AES and SEM/EDS, and OSL dating. ...
Comment on "Encryption and decryption of images with chaotic map lattices" [Chaos 16, 033118 (2006)]
(American Institute of Physics Inc., 2008-09)
In this paper, we comment on the chaotic encryption algorithm proposed by A. N. Pisarchik et al. [Chaos 16, 033118 (2006)]. We demonstrate that the algorithm is not invertible. We suggest simple modifications that can ...
Andijon'da Nima Bo'ldi? Özbekistan'da terör, güvenlik ve demokrasi
(2008)
1991 yılında Sovyetler Birliği’nin çözülmesiyle birlikte Soğuk Savaş sona ermiş ve tüm Sovyet coğrafyasında olduğu gibi Orta Asya’da da yeni bağımsız devletler ortaya çıkmıştır. Yeni dönemde uluslararası sistemde güvenlik ...
The statistics of energy states of a Hookean model for proteins
(TÜBİTAK, 2000)
A generic model of a random polypeptide chain, with discrete torsional degrees of freedom and Hookean springs connecting pairs of hydrophobia residues, reproduces the energy probability distribution of real proteins over ...
Optically stimulated luminescence to date coastel dunes and a possible tsunami layer on the Kavak Delta (Saros Gulf, NW Turkey)
(Scientific Technical Research Council Turkey-Tubitak, 2009-01-21)
Optically stimulated luminescence (OSL) dating was used to determine the timing of initial dune formation and reconstruct the evolution of coastal dunes that developed on the Kavak Delta, Saros Gulf, Turkey. Along a 500-mlong ...
New criteria for the existence of stable equilibrium points in nonsymmetric cellular neural networks
(2003)
This paper presents new criteria for the existence of stable equilibrium points in the total saturation region for cellular neural networks (CNNs). It is shown that the results obtained can be used to derive some complete ...
Tıbbi ultrasonik kanal içi görüntüleme için yeni yöntemler
(Tübitak, 2008-09)
Yakın zamanda yapılan çalışmalarımızdaki yaklaşımda, aktif kanal sayısını azaltmak için fazlalık (redundant) gönderme-alma eleman ikilileri azalırken gerekli olan (non-redundant) gönderme-alma eleman ikilileri korunmaktadır. ...
