Chebyshev nets formed by Ricci curves in a 3-dimensional Weyl space
(Elsevier Science Bv, 2005)In this paper Ricci curves in a 3-dimensional Weyl space W-3(g T) are defined and it is shown that any 3-dimensional Chebyshev net formed by the three families of Ricci curves in a W-3(g T) having a definite metric and ... -
Chelate extraction of transition metal ions by ethylene diamine diacetic acid with n-substituted octadecyl groups
(Taylor & Francis Inc, 2002)An organic-soluble chelating agent NN'-di-n-octadecyl ethylenediamine-NN'-diacetic acid (DOED) has been synthesized in two steps by (i) condensation of dibromoethane with 1-amino octadecane (octadecylamine) and (ii) ... -
Cis-cyclopropylamines as mechanism-based inhibitors of monoamine oxidases
(Wiley-Blackwell, 2015)Cyclopropylamines inhibitors of monoamine oxidases (MAO) and lysine-specific demethylase (LSD1) provide a useful structural scaffold for the design of mechanism-based inhibitors for treatment of depression and cancer. For ... -
Classification Of Distinct Conformers Of Beta < 2-Adrenergic Receptor (Beta 2-AR) Based On Binding Affinity Of Ligands Through Docking Studies
(Amer Chemical Soc, 2016)B2AR reseptörü, akciğerlerin rahatlamasında ve kardiyovasküler fizyolojide rol oynamasıyla önemli bir ilaç hedefidir. Bu çalışmada, çeşitli B2AR konformasyonlarını aktif veya inaktif olarak sınıflandırmak amacıyla, ... -
A Clustering-Based Approach for Improving the Accuracy of UWB Sensor-Based Indoor Positioning System
(Hindawi LTD, 2019)There are several methods which can be used to locate an object or people in an indoor location. Ultra-wideband (UWB) is a specifically promising indoor positioning technology because of its high accuracy, resistance to ... -
Code shift keying impulse modulation for UWB communications
(IEEE-INST Electrical Electronics Engineers Inc, 2008)In this paper the system performance of M-ary code shift keying (MCSK) impulse modulation is studied in detail and compared to M-ary pulse position modulation (MPPM) under single- and multi-user scenarios. For that bounds ... -
Collective enhancement of nuclear state densities by the shell model Monte Carlo approach
(IOP Publishing Ltd, 2015)The shell model Monte Carlo (SMMC) approach allows for the microscopic calculation of statistical and collective properties of heavy nuclei using the framework of the configuration-interaction shell model in very large ... -
Collectivity in Heavy Nuclei in the Shell Model Monte Carlo Approach
(EDP Sciences, 2014)The microscopic description of collectivity in heavy nuclei in the framework of the configuration-interaction shell model has been a major challenge. The size of the model space required for the description of heavy nuclei ... -
A combined fuzzy AHP-simulation approach to CAD software selection
(Taylor & Francis Ltd, 2010)In this paper a combined approach where the fuzzy analytic hierarchy process (AHP) and simulation come together is presented to select the best computer-aided design (CAD) software out of the available options in the market. ... -
Comparison of cation effects on phase transitions of kappa and iota carrageenan
(European Polymer Federation, 2010)Phase transitions of kappa and iota carrageenan in KCl NaCl and CaCl2 solutions were separately studied during heating and cooling processes by using fluorescence technique. Scattered light I-SC and fluorescence intensity ... -
Comparison of Compressed Sensing Based Algorithms for Sparse Signal Reconstruction
(IEEE, 2016)Compressed sensing theory shows that any signal which is defined as sparse in a given domain can be reconstructed using fewer linear projections instead of using all Nyquist-rate samples. In this paper we investigate basis ... -
A comparison of fluorescence and UV-visible spectrometry techniques for thermal phase transitions of agarose gels
(Springer, 2015)In this study thermoreversible phase transitions of high (HMP) and low (LMP) melting point agarose gels were investigated by using the UV-vis and fluorescence spectroscopy techniques. Pyranine was added to the aqueous ... -
Competitive intelligence and information technology adoption of SMEs in Turkey: Diagnosing current performance and identifying barriers
