On the eigenvalues and eigenvectors of a lorentzian rotation matrix by using split quaternions
(Advances in Applied Clifford Algebras, 2014)In this paper, we examine eigenvalue problem of a rotation matrix in Minkowski 3 space by using split quaternions. We express the eigenvalues and the eigenvectors of a rotation matrix in term of the coefficients of the ... -
On focal curves of null Cartan curves
(Turkish Journal of Mathematics, 2017)The focal curve, which is determined as the locus of centers of osculating pseudo-spheres of a null Cartan curve, is investigated in Minkowski (n+2)-space Mn+2. Moreover, a curve called acceleration focal curve of a null ... -
Rotations on a lightcone in minkowski 3-Space
(Advances in Applied Clifford Algebras, Springer, 2017)In this paper the generalization of the rotations on any lightcone in Minkowski 3-space ℝ1,2𝑔 is given. The rotation motion on the lightcone is examined by means of a bilinear form and Lorentzian notions. We use the ... -
Optimization of hydrothermal synthesis of Ce3+ co-doped NaYF4, Yb3+, Er3+upconversion nanoparticles and investigation of their size, morphology, and phase transitions.
(ICENS, 2019)In this study, the synthesis of water-soluble polyethyleneimine (PEI) modified UCNPs which were prepared by a hydrothermal method have been reported. The resultant UCNPs were small size and hexagonal β-phase structure ... -
Multifunctional magnetic nanocarrier: synthesis, characterization and pH-responsive doxorubicin release profile
(2019)In this study, carboxymethyl cellulose (CMC) functionalized superparamagnetic iron oxide nanoparticles (SPIONs) have been synthesized as a novel theranostic platform which enables magnetic resonance (MR) imaging-guided and ... -
Evaluation of reinforcing bars ratio effects on SCC beam-column joint performance
(Uludağ University Journal of The Faculty of Engineering, 2019)Beam-column joints require a high ductility during the unexpected loadings that necessitate the need for ductile concrete in such unprotected locations. Alternatively, self-compacting concrete (SCC) is a sort of concrete ... -
Seismic retrofit of full-scale substandard extended rectangular RC columns through CFRP jacketing: test results and design recommendations
(Journal of Composites for Construction, 2019)Brittle behavior of substandard columns during earthquakes is among the most common reasons of structural failures. Because capacity design principles and ductile detailing concepts have not been properly adopted during ... -
Number of design gyrations for 100 mm compacted asphalt mixtures modified with polypropylene
(Journal of Engineering Research, 2018)There is no standard accepted by highway authorities on the compaction procedures of 100 mm diameter gyratory compactor specimens. In previous studies on gyratory compaction, the utilisation of either coring from 150 mm ... -
Beyond the institutional logics: international level systemic analysis of EU-Turkish relations
(Turkish Studies, 2013)This article aims to explain the slowing down of European Union (EU)–Turkish relations since the start of the accession negotiations in 2005 with international level systemic analysis. For this purpose, it examines the ... -
Discussion networks in Turkey: a social capital approach to informal social relations
(Southeast European and Black Sea Studies, 2019)The present study inquires into the informal social network underpinnings of generalized trust in Turkey. For this purpose, it utilizes survey data on Turkish discussion networks. The findings show that informal social ... -
Civic space in Turkey: a social capital approach to civil society
(Turkish Studies, 2017)The present study explores civil society organizations’ (CSOs) civic and political potential in Turkey. For this purpose, it generates original data from Antalya and utilizes social network analysis to analyze the CSOs’ ... -
Sonic effects on the appreciation of architectural aesthetics of architectural design projects
(International Civil Engineering & Architecture Conference, 2019)Appreciation of visual aesthetics is always connected with the visual experience of art objects. Yet, as the human senses are all connected and work in a comprehensive complex way, there is always a need to investigate the ... -
