Evaluating learning management systems: Hexagonal e-learning assessment model (HELAM)
Ozkan, Sevgi; Koseler, Refika; Baykal, Nazife (null; 2008-12-01)
A considerable amount of research has been conducted on evaluating success of information systems. However, there has been little research addressing the conceptualization and measurement of elearning systems success within educational organizations. Evaluation of information systems within the growing e-learning sector is currently receiving attention, and this research study proposes a conceptual e-learning assessment model, HELAM (Hexagonal e-Learning Assessment Model). HELAM has been applied to 23 e-lea...
Intergroup relations in a changing political context: the case of veiled and unveiled university students in Turkey
Hortacsu, N (Wiley, 2000-09-01)
The present study investigated (a) the underlying dimensions of different measures related to identification , categorization, ingroup, bias and contact conditions, and (b) relations between two groups related to an important social controversy over time. Questionnaires were administered to veiled (minority) and unveiled (majority) Turkish female university students during the fall of 1996 and the spring of 1998. Results of factor analysis revealed three factors, namely: tolerance, including percieved outgr...
Performance based assessment of number of equivalent uniform cyclic stress scheme
Altıncı, Eray; Çetin, Kemal Önder; Department of Civil Engineering (2019)
Assessment of cyclic (seismic) response of soils is considered to be one of the most interesting research areas of geotechnical engineering. Cyclic loading-induced stresses cause accumulation of shear strains and generation of excess pore water pressure, which are accompanied by reduction in stiffness. In the most extreme cases, this process leads to soil liquefaction. As opposed to the random nature of earthquake waves, it is generally preferred to apply uniform loading cycles to undisturbed or reconstitut...
Is it single-metal homogeneous or polymetallic heterogeneous catalysis? Further investigation of the catalytically active species in benzene hydrogenation beginning with [RhCp*Cl 2] 2 via operando-XAFS, kinetic and poisoning studies
Bayram, Ercan; Linehan, John C.; Finke, Richard G.; Fulton, John; Roberts, John A. S.; Smurthwaite, Tricia D.; Özkar, Saim; Szymczak, Nathaniel K. (2011-12-01)
Previous investigation (Hagen et al. J. Am. Chem. Soc. 2005, 127, 4423) for benzene hydrogenation starting with [RhCp*Cl 2] 2 at 100 °C and 50 atm initial H 2 pressure concluded that the true catalyst was most likely Rh(0) nanoparticles on the basis of sigmoidal kinetics, Rh(0) precipitate, and positive Hg(0) poisoning studies. There was, at the time, no other plausible hypothesis for the true catalyst in light of the extant data. Further investigation via operando-XAFS provides a new hypothesis for the act...
Variational Bayes methods for random matrix-based extended target tracking
Tuncer, Barkın; Özkan, Emre; Department of Electrical and Electronics Engineering (2022-2-10)
In this thesis, we investigate two major topics; Random matrix-based models using variational Bayes inference for extended target tracking and shape classification algorithms for tracking applications. In the scope of this thesis, we have derived two novel random matrix-based tracking algorithms. First, to represent the extent of dynamic objects as an ellipsoid with a time-varying orientation angle, and secondly, to estimate the extent of the object or a group of objects with more than one ellipsoid. In bo...
