      Zeynep, C. Y.; Bulbul, A.; Capin, T. (Association for Computing Machinery, 2013)
      During the visualization of 3D content, using the depth cues selectively to support the design goals and enabling a user to perceive the spatial relationships between the objects are important concerns. In this novel ...
    • How content management problem of a remote laboratory system can be handled by integrating an open source learning management system? Problems and solutions 

      Özdoğru, B.; Cagıltay, N. E. (2007)
      This paper represents the design and implementation of the integration process of an open source learning management system (LMS) to the remote laboratory platform. The reason of using a learning management system is to ...
    • Information arts and information science: time to unite? 

      Karamuftuoglu, M. (Wiley, 2006)
      This article explicates the common ground between two currently independent fields of Inquiry, namely information arts and information science, and suggests a frame-work that could unite them as a single field of study. ...
    • L1 norm based multiplication-free cosine similarity measures for big data analysis 

      Akbas, C.E.; Bozkurt, A.; Arslan, M.T.; Aslanoglu H.; Cetin, A.E. (Institute of Electrical and Electronics Engineers Inc., 2014)
      The cosine similarity measure is widely used in big data analysis to compare vectors. In this article a new set of vector similarity measures are proposed. New vector similarity measures are based on a multiplication-free ...
