    • An animation system for fracturing of rigid objects 

      Küçükyilmaz, Ayşe; Özgüç, Bülent (Springer, Berlin, Heidelberg, 2005)
      This paper describes a system for the animation of fracturing brittle objects. The system combines rigid body simulation methods with a constraint-based model to animate fracturing of arbitrary polyhedral shaped objects ...
    • Incremental materialization of object-oriented views 

      Alhajj, R.; Elnagar, A. (Elsevier, 1999)
      We present an approach to handle incremental materialization of object-oriented views. Queries that define views are implemented as methods that are invoked to compute corresponding views. To avoid computation from scratch ...
    • An object oriented intelligent tutoring system for teaching set theory 

      Cankat, Emel (Bilkent University, 1991)
      In this thesis an Intelligent Tutoring System (ITS) to teach set theory is designed and implemented using an object-oriented approach. The program is implemented on an IBM PS/2 and PC compatibles using the Turbo Pascal ...
    • Object-oriented query language facilitating construction of new objects 

      Alhajj, R.; Arkun, M. E. (Elsevier, 1993)
      In object-oriented database systems, messages can be used to manipulate the database; however, a query language is still a required component of any kind of database system. In the paper, we describe a query language for ...
    • Query model for object-oriented databases 

      Alhajj, Reda; Arkun, M. Erol (IEEE, 1993-04)
      A query language should be a part of any database system. While the relational model has a well defined underlying query model, the object-oriented database systems have been criticized for not having such a query model. ...
    • Reusability and schema evolution in object - oriented query models 

      Polat, F.; Alhajj, R. (ASME, New York, NY, United States, 1996)
      In this paper, we have benefited from having an object algebra maintaining closure that makes it possible to have the output from a query persistent in the hierarchy. Based on this, it is possible to maximize reusability ...
