This thesis focuses on three of the main components of an e-learning system: Infrastructure model, data integration and personalization. For the infrastructure model, our aim is to get best use of heterogeneously structured, geographically distributed data resources. Therefore, a detailed analysis of the available infrastructure models is carried out and an open source reference implementation based on grid technology is implemented. Furthermore, a simple data integration mechanism is proposed for the suggested reference implementation. For personalization, a statistical algorithm is proposed based on extracting and utilizing the learner model. The learner model based on Felder-Silverman learning style is extracted automatically using NBTree classification algorithm in conjunction with Binary relevance classifier for basic science learners. Experimental results show that the performance of the proposed automated learner modelling approach is consistent with the results, obtained by the questionnaires traditionally used for learning style assessment. In the thesis, the classification results are further utilized for providing the user with personalized queries.

A deep learning approach for the transonic flow field predictions around airfoils Duru, Cihat; Alemdar, Hande; Baran, Özgür Uğraş (2022-01-01) Learning from data offers new opportunities for developing computational methods in research fields, such as fluid dynamics, which constantly accumulate a large amount of data. This study presents a deep learning approach for the transonic flow field predictions around airfoils. The physics of transonic flow is integrated into the neural network model by utilizing Reynolds-averaged Navier–Stokes (RANS) simulations. A detailed investigation on the performance of the model is made both qualitatively and quant...
An Evolutionary Genetic Algorithm for Optimization of Distributed Database Queries Sevinc, Ender; Coşar, Ahmet (2011-05-01) High-performance low-cost PC hardware and high-speed LAN/WAN technologies make distributed database (DDB) systems an attractive research area where query optimization and DDB design are the two important and related problems. Since dynamic programming is not feasible for optimizing queries in a DDB, we propose a new genetic algorithm (GA)-based query optimizer (new genetic algorithm (NGA)) and compare its performance with random and optimal (exhaustive) algorithms. We perform experiments on a synthetic data...
A Petri Net-based inference network for design automation under nondeterminism applied to mechatronic systems Erden, Zühal; Erkmen, Aydan Müşerref; Erden, Abdülkadir (1998-09-11) This paper introduces the completed part of an ongoing research, in which a Petri Net-based design inference network is developed for the representation and analysis of the functions and their interrelationships through information flow for the conceptual design stage of mechatronic systems in order to facilitate design automation. The theoretical framework behind the network is based on transition of Hybrid Automata into Petri Nets and application of this framework is introduced by a mechatronic design exa...
A Distributed Online Curriculum and Courseware Development Model ONAY DURDU, PINAR; Yalabik, Nese; Çağıltay, Kürşat (2009-01-01) A distributed online curriculum and courseware development model (DONC(2)) is developed and tested in this study. Courseware development teams which may work in different institutions who need to develop high quality, reduced cost, on time products will be the users of DONC(2). The related features from the disciplines of instructional design and software engineering were combined. The research is conducted as a collective case study, including four cases with distinctive characteristics to reveal the sever...
An activity planning and progress following tool for self-directed distance learning Sen, N; Yalabik, N (2003-01-01) This paper presents an overview of the design and implementation of an Activity Planning and Progress Following Tool (APT) for e-learning. APT is a software based support tool designed to assist learners with their self directed distance learning (SDDL). A literature survey for the additional components of Learning Management Systems (LMS) that are needed for SDDL is conducted. As a result, the importance of "planning", "feedback" and "resources" proper-ties are revealed. In the continuation of the study, A...
