      In recent years, vast amounts of data of different kinds, from pictures and videos from our cameras to software logs from sensor networks and Internet routers operating day and night, are being generated. This has led to ...
    • Access pattern-based code compression for memory-constrained systems 

      Ozturk, O.; Kandemir, M.; Chen, G. (Association for Computing Machinery, 2008-09)
      As compared to a large spectrum of performance optimizations, relatively less effort has been dedicated to optimize other aspects of embedded applications such as memory space requirements, power, real-time predictability, ...
    • ACMICS: an agent communication model for interacting crowd simulation 

      Kullu, K.; Güdükbay U.; Manocha, D. (Springer, 2017)
      Behavioral plausibility is one of the major aims of crowd simulation research. We present a novel approach that simulates communication between the agents and assess its influence on overall crowd behavior. Our formulation ...
    • Activating mutations of STAT5B and STAT3 in lymphomas derived from γδ-T or NK cells 

      Küçük, C.; Jiang, B.; Hu X.; Zhang W.; Chan J.K.C.; Xiao W.; Lack, N.; Alkan, C.; Williams J.C.; Avery, K.N.; Kavak P.; Scuto, A.; Sen, E.; Gaulard P.; Staudt L.; Iqbal J.; Zhang W.; Cornish, A.; Gong Q.; Yang Q.; Sun H.; D'Amore F.; Leppä, S.; Liu W.; Fu, K.; De Leval L.; McKeithan, T.; Chan W.C. (Nature Publishing Group, 2015)
      Lymphomas arising from NK or γδ-T cells are very aggressive diseases and little is known regarding their pathogenesis. Here we report frequent activating mutations of STAT3 and STAT5B in NK/T-cell lymphomas (n=51), γδ-T-cell ...
    • Active node determination for correlated data gathering in wireless sensor networks 

      Karasabun, E.; Korpeoglu, I.; Aykanat, C. (Elsevier BV, 2013-04-07)
      In wireless sensor network applications where data gathered by different sensor nodes is correlated, not all sensor nodes need to be active for the wireless sensor network to be functional. Given that the sensor nodes that ...
    • Adapting iterative-improvement heuristics for scheduling file-sharing tasks on heterogeneous platforms 

      Kaya, K.; Uçar, B.; Aykanat, C. (2008)
      We consider the problem of scheduling an application on a computing system consisting of heterogeneous processors and one or more file repositories. The application consists of a large number of file-sharing, otherwise ...
    • Adaptive decomposition and remapping algorithms for object-space-parallel direct volume rendering of unstructured grids 

      Aykanat, C.; Cambazoglu, B. B.; Findik, F.; Kurc, T. (Academic Press, 2007-01)
      Object space (OS) parallelization of an efficient direct volume rendering algorithm for unstructured grids on distributed-memory architectures is investigated. The adaptive OS decomposition problem is modeled as a graph ...
