  • Incentive-based resource assignment and regulation for collaborative cloud services in community networks 

    Khan, Amin M.; Büyükşahin, Ümit C.; Freitag, Felix (ACADEMIC PRESS INC ELSEVIER SCIENCE, 525 B ST, STE 1900, SAN DIEGO, CA 92101-4495 USAJournal Of Computer And System Sciences, 2015-12)
    Community networks are a successful example of a collective where communities operate ICT infrastructure based on the principle of reciprocal sharing of network bandwidth. Cloud computing, common in today's Internet, has ...
  • Solving Models of Controlled Dynamic Planar Rigid-Body Systems with Frictional Contact 

    Greenfield, Aaron; Saranlı, Uluç; Rizzi, Alfred A. (SAGE PublicationsThe International Journal of Robotics Research, 2005-11)
    Effective modeling and control of multibody systems interacting with their environment through frictionol contact remain a challenging problem. In this paper we address the planar version of this problem by developing a ...
  • Mumford-Shah Regularizer with Contextual Feedback 

    Erdem, Erkut; Tarı, Zehra Sibel (Springer Science and Business Media LLCJournal of Mathematical Imaging and Vision, 2008-7-24)
    We present a simple and robust feature preserving image regularization by letting local region measures modulate the diffusivity. The purpose of this modulation is to disambiguate low level cues in early vision. We interpret ...
  • The learning of adjectives and nouns from affordance and appearance features 

    Yürüten, Onur; Şahin, Erol; Kalkan, Sinan (SAGE PublicationsAdaptive Behavior, 2013-8-22)
    We study how a robot can link concepts represented by adjectives and nouns in language with its own sensorimotor interactions. Specifically, an iCub humanoid robot interacts with a group of objects using a repertoire of ...
  • CRoM and HuspExt: Improving Efficiency of High Utility Sequential Pattern Extraction 

    Alkan, Oznur Kirmemis; Karagöz, Pınar (Institute of Electrical and Electronics Engineers (IEEE)IEEE Transactions on Knowledge and Data Engineering, 2015-10-1)
    High utility sequential pattern mining has been considered as an important research problem and a number of relevant algorithms have been proposed for this topic. The main challenge of high utility sequential pattern mining ...
  • Building Detection With Decision Fusion 

    Senaras, Caglar; Ozay, Mete; Yarman Vural, Fatoş Tunay (Institute of Electrical and Electronics Engineers (IEEE)IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2013-6)
    A novel decision fusion approach to building detection problem in VHR optical satellite images is proposed. The method combines the detection results of multiple classifiers under a hierarchical architecture, called Fuzzy ...
  • Performance Analysis of Data Mining Techniques for Improving the Accuracy of Wind Power Forecast Combination 

    Koksoy, Ceyda Er; Ozkan, Mehmet Baris; Küçük, Dilek; Bestil, Abdullah; Sonmez, Sena; Buhan, Serkan; Demirci, Turan; Karagöz, Pınar; Birturk, Aysenur (Springer International PublishingData Analytics for Renewable Energy Integration, 2015)
    Efficient integration of renewable energy sources into the electricity grid has become one of the challenging problems in recent years. This issue is more critical especially for unstable energy sources such as wind. The ...
  • Static index pruning in web search engines 

    Altıngövde, İsmail Sengör; Ozcan, Rifat; Ulusoy, Özgür (Association for Computing Machinery (ACM)ACM Transactions on Information Systems, 2012-2-1)
    Static index pruning techniques permanently remove a presumably redundant part of an inverted file, to reduce the file size and query processing time. These techniques differ in deciding which parts of an index can be ...
  • Goal emulation and planning in perceptual space using learned affordances 

    Ugur, Emre; Oztop, Erhan; Şahin, Erol (Elsevier BVRobotics and Autonomous Systems, 2011-7)
    In this paper, we show that through self-interaction and self-observation, an anthropomorphic robot equipped with a range camera can learn object affordances and use this knowledge for planning. In the first step of learning, ...
  • Large-Scale Signaling Network Reconstruction 

    Hashemikhabir, Seyedsasan; Ayaz, Eyup Serdar; Kavurucu, Yusuf; Can, Tolga; Kahveci, Tamer (Institute of Electrical and Electronics Engineers (IEEE)IEEE/ACM Transactions on Computational Biology and Bioinformatics, 2012-11)
    Reconstructing the topology of a signaling network by means of RNA interference (RNAi) technology is an underdetermined problem especially when a single gene in the network is knocked down or observed. In addition, the ...
  • Modeling and querying fuzzy spatiotemporal databases 

    Sözer, Aziz; Yazıcı, Adnan; Oğuztüzün, Halit; Taş, Osman (Elsevier BVInformation Sciences, 2008-10)
    Modeling spatiotemporal data, in particular fuzzy and complex spatial objects representing geographic entities and relations, is a topic of great importance ill geographic information systems, computer vision, environmental ...
  • Employment of an evolutionary heuristic to solve the target allocation problem efficiently 

    Bayrak, Ahmet Engin; Polat, Faruk (Elsevier BVInformation Sciences, 2013-2)
    In this study, we investigated different optimization approaches for the resource allocation problem in the preparation of Air Tasking Orders (ATOs) and analyzed their performances. We developed a genetic algorithm with ...
  • Making recommendations by integrating information from multiple social networks 

    Ozsoy, Makbule Gulcin; Polat, Faruk; Alhajj, Reda (Springer Science and Business Media LLCApplied Intelligence, 2016-7-1)
    It is becoming a common practice to use recommendation systems to serve users of web-based platforms such as social networking platforms, review web-sites, and e-commerce web-sites. Each platform produces recommendations ...
  • Embedding Shapes without Predefined Parts 

    Keles, Hacer Yalim; Özkar, Mine; Tarı, Zehra Sibel (SAGE PublicationsEnvironment and Planning B: Planning and Design, 2010-8)
