Algebraic connectivity and degree sequences of trees
(Elsevier Science Inc, 2009-01-15)
We investigate the structure of trees that have minimal algebraic connectivity among all trees with a given degree sequence. We show that such trees are caterpillars and that the vertex degrees are non-decreasing on every ...
Thermoluminescence as a probe in bioactivity studies; the case of 58S sol-gel bioactive glass
(IOP Publishing Ltd, 2011-10-05)
The formation of a carbonated hydroxyapatite (HCAp) layer on the surface of bioactive materials is the main reaction that takes place upon their immersion in physiological fluids. To date, all techniques used for the ...
The firing temperature of pottery from ancient Mesopotamia, Turkey, using luminescence methods: a case study for different grain-size fractions
(Wiley-Blackwell, 2014-10)
The assessment of the firing temperature of a prehistoric pottery sample collected from ancient Mesopotamia, Turkey was studied using luminescence techniques. The methods for this estimation involved the observation of the ...
Numerical simulation of blow-up solutions for the generalized Davey-Stewartson system
(Taylor & Francis Ltd, 2011-03)
Blow-up solutions for the generalized Davey-Stewartson system are studied numerically by using a split-step Fourier method. The numerical method has spectral-order accuracy in space and first-order accuracy in time. To ...
Some notes on spectra of cographs
(Charles Babbage Res Ctr, 2011-07)
A cograph is a P-4-free graph. We first give a short proof of the fact that 0 (-1) belongs to the spectrum of a connected cograph (with at least two vertices) if and only if it contains duplicate (resp. coduplicate) vertices. ...
Extended reductive perturbation method and its relation to the re-normalization method
(Walter De Gruyter GMBH, 2013-10-25)
In this work, by utilizing the extended reductive perturbation method, we studied the propagation of weakly nonlinear waves in a collisionless cold plasma and formally obtained the governing evolution equations of various ...
Dendrimers are the unique chemical trees with maximum spectral radius
(Univ Kragujevac, 2012)
It is shown that dendrimers have maximum spectral radius and maximum Collatz-Sinogowitz index among all chemical trees of given size. The result is also generalized for the class of chemical trees with prescribed number ...
A survey on Near Field Communication (NFC) technology
(Springer, 2013-08)
Near Field Communication (NFC) as a promising short range wireless communication technology facilitates mobile phone usage of billions of people throughout the world that offers diverse services ranging from payment and ...
Foresighting FLOSS (free/libre/open source software) from a developing country perspective: The case of Turkey
(Elsevier Science BV, 2011-12)
Since free/libre open source software (FLOSS) promotes collaboration and contributions from different parties in software production and innovation processes, it can create a unique opportunity for developing countries, ...
Attachment to god, stressful life events, and changes in psychological distress
(Springer Heidelberg, 2012-01)
Considerable research shows that social relationships, attachments, and support systems promote emotional well-being. The present study adds to this literature by examining the connection between attachments to God and ...
