      An important motivation for work on legged robots has always been their potential for high-performance locomotion on rough terrain. Nevertheless, most existing control algorithms for such robots either make rigid assumptions ...
    • A real-time concurrency control protocol for main-memory database systems 

      Ulusoy, Ö.; Buchmann, A. (Elsevier, 1998)
      Protocols developed so far for concurrency control in real-time database systems have assumed a dynamic acquisition of data resources as it is impossible to predict which instances of relations will actually be accessed ...
    • Real-time fire and flame detection in video 

      Dedeoğlu, Yigithan; Töreyin, B. Ugur; Güdükbay, Uğur; Çetin, A. Enis (IEEE, 2005)
      This paper proposes a novel method to detect fire and/or flame by processing the video data generated by an ordinary camera monitoring a scene. In addition to ordinary motion and color clues, flame and fire flicker is ...
    • Real-time smoke and flame detection in video 

      Töreyin, B. Uğur; Dedeoğlu, Yiğithan; Çetin, Ahmet Enis (IEEE, 2005)
      A novel method to detect smoke and/or flame by processing the video data generated by an ordinary camera monitoring a scene is proposed. It is assumed the camera is stationary. Since the smoke is semi-transparent, edges ...
    • Real-time transaction scheduling in database systems 

      Ulusoy, Ö.; Belford, G. G. (1993)
      A database system supporting a real-time application, which can be called "a real-time database system (RTDBS)", has to provide real-time information to the executing transactions. Each RTDB transaction is associated with ...
    • Real-time virtual fitting with body measurement and motion smoothing 

      Gültepe, U.; Güdükbay U. (Pergamon Press, 2014)
      We present a novel virtual fitting room framework using a depth sensor, which provides a realistic fitting experience with customized motion filters, size adjustments and physical simulation. The proposed scaling method ...
    • Realistic modeling of spectator behavior for soccer videogames with CUDA 

      Ylmaz, E.; Molla, E.; Yıldız, C.; İşler V. (2011)
      Soccer has always been one of the most popular videogame genres. When designing a soccer game, designers tend to focus on the game field and game play due to the limited computational resources, and thus the modelling of ...
    • Realistic rendering and animation of a multi-layered human body model 

      Yeşil, Mehmet Şahin; Güdükbay, Uğur (IEEE, 2006)
      A framework for realistic rendering of a multi-layered human body model is proposed in this paper. The human model is composed of three layers: skeleton, muscle, and skin. The skeleton layer, represented by a set of joints ...
    • Realizing the potential of blockchain technologies in genomics 

      Ozercan, H. I.; Ileri, A. M.; Ayday, E.; Alkan C. (Cold Spring Harbor Laboratory Press, 2018)
      Genomics data introduce a substantial computational burden as well as data privacy and ownership issues. Data sets generated by high-throughput sequencing platforms require immense amounts of computational resources to ...
