    • An archiving model for a hierarchical information storage environment 

      Moinzadeh, K.; Berk, E. (Elsevier, 2000)
      We consider an archiving model for a database consisting of secondary and tertiary storage devices in which the query rate for a record declines as it ages. We propose a `dynamic' archiving policy based on the number of ...
    • Distributed scheduling: a review of concepts and applications 

      Toptal, A.; Sabuncuoglu, I. (Taylor & Francis, 2010)
      Distributed scheduling (DS) is an approach that enables local decision makers to create schedules that consider local objectives and constraints within the boundaries of the overall system objectives. Local decisions from ...
    • Issues in commonsense set theory 

      Pakkan, M.; Akman, V. (Springer/Kluwer Academic Publishers, 1994)
      The success of set theory as a foundation for mathematics inspires its use in artificial intelligence, particularly in commonsense reasoning. In this survey, we briefly review classical set theory from an AI perspective, ...
    • Lossless image compression by LMS adaptive filter banks 

      Öktem, R.; Çetin, A. E.; Gerek, O. N.; Öktem, L.; Egiazarian, K. (Elsevier, 2001)
      A lossless image compression algorithm based on adaptive subband decomposition is proposed. The subband decomposition is achieved by a two-channel LMS adaptive filter bank. The resulting coefficients are lossy coded first, ...
    • Novelty detection using soft partitioning and hierarchical models 

      Ergen, T.; Gokcesu, K.; Simsek, M.; Kozat, S. S. (Institute of Electrical and Electronics Engineers Inc., 2017)
      In this paper, we study novelty detection problem and introduce an online algorithm. The algorithm sequentially receives an observation, generates a decision and then updates its parameters. In the first step, to model the ...
    • PHR: A parallel hierarchical radiosity system with dynamic load balancing 

      Sinop, A.; Abacı, T.; Akkuş Ü.; Gürsoy, A.; Güdükbay U. (Springer, 2005)
      In this paper, we present a parallel system called PHR for computing hierarchical radiosity solutions of complex scenes. The system is targeted for multi-processor architectures with distributed memory. The system evaluates ...
    • Retrieval of Ottoman documents 

      Ataer, Esra; Duygulu, Pınar (ACM, 2006-10)
      There is a growing need to access historical Ottoman documents stored in large archives and therefore managing tools for automatic searching, indexing and transcription of these documents is required. In this paper, we ...
    • 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 ...
    • Scheduling of automated guided vehicles in a decision making hierarchy 

      Aktürk, M. S.; Yılmaz, H. (Taylor & Francis, 1996)
      Scheduling efforts made without considering the special limitations of the material handling system might lead to infeasible results. An analytical model is proposed, first, to incorporate the automated guided vehicle (AGV) ...
    • Tracking motion and intensity variations using hierarchical 2-D mesh modeling for synthetic object transfiguration 

      Toklu, C.; Erdem, A. T.; Sezan, M. I.; Tekalp, A. M. (1996-11)
      We propose a method for tracking the motion and intensity variations of a 2-D mildly deformable image object using a hierarchical 2-D mesh model. The proposed method is applied to synthetic object transfiguration, namely, ...
    • Use of intuitive tools to enhance student learning and user experience 

      Altın, Rukiye; Bektik, Mustafa; Ekşioǧlu, Nuray; Koray, Can; Öner, Ömer Canbek; Sadetaş, Merve; Şener, Hilal; Şimşek, D.; Ma, C.-C.; Price, C.; Routh, C.R. (ACM, 2009)
      Most user interfaces today present system functions by use of verbal or iconic symbols on static 2D menu pages organized in a hierarchical system [1]. This is unnatural to all human beings and must be learned, thus being ...
