    • 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 ...

    • Computational homogenization of soft matter friction: Isogeometric framework and elastic boundary layers 

      Temizer, I. (John Wiley and Sons Ltd, 2014)
      SUMMARY: A computational contact homogenization framework is established for the modeling and simulation of soft matter friction. The main challenges toward the realization of the framework are (1) the establishment of a ...

    • A derivation of Lovász' theta via augmented lagrange duality 

      Pınar, M. Ç. (E D P Sciences, 2003)
      A recently introduced dualization technique for binary linear programs with equality constraints, essentially due to Poljak et al. [13], and further developed in Lemar´echal and Oustry [9], leads to simple alternative ...

    • Image reconstruction for Magnetic Particle Imaging using an Augmented Lagrangian Method 

      Ilbey S.; Top C.B.; Çukur, Tolga; Sarıtaş, Emine Ülkü; Guven H.E. (IEEE, 2017)
      Magnetic particle imaging (MPI) is a relatively new imaging modality that images the spatial distribution of superparamagnetic iron oxide nanoparticles administered to the body. In this study, we use a new method based on ...

    • An interior point method for isogeometric contact 

      Temizer, I.; Abdalla, M. M.; Gürdal, Z. (Elsevier, 2014)
      The interior point method is applied to frictionless contact mechanics problems and is shown to be a viable alternative to the augmented Lagrangian approach. The method is derived from a mixed formulation which induces a ...

    • Marginal allocation algorithm for nonseparable functions 

      Yüceer, Ü. (Taylor & Francis, 1999)
      Marginal allocation algorithm is implemented to discrete allocation problems with nonseparable objective functions subject to a single linear constraint. A Lagrangian analysis shows that the algorithm generates a sequence ...

    • Optimizing local memory allocation and assignment through a decoupled approach 

      Diouf, B.; Öztürk, Özcan; Cohen, A. (Springer, 2010-10)
      Software-controlled local memories (LMs) are widely used to provide fast, scalable, power efficient and predictable access to critical data. While many studies addressed LM management, keeping hot data in the LM continues ...
