  • Dokeroglu, Tansel; Sevinc, Ender; Cosar, Ahmet (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2019)
    We propose hybrid Artificial Bee Colony (ABC) optimization algorithms for the well-known Quadratic Assignment Problem (QAP). Large problem instances of the QAP are still very challenging. Scientists have not discovered any ...
  • Bulbul, Abdullah; Arpa, Sami; Capin, Tolga (PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2014)
    We present a model to determine the perceptually significant elements in animated 3D scenes using a motion-saliency method. Our model clusters vertices with similar motion-related behaviors. To find these similarities, for ...
  • Cebeci, B.; Celikcan, U.; Çapın, Tolga (John Wiley and Sons Ltd, 2019)
    Previous studies showed that virtual reality (VR) environments can affect emotional state and cause significant changes in physiological responses. Aside from these effects, inadvertently induced cybersickness is a notorious ...
  • Avenoglu, Bilgin; Eren, P. Erhan (SPRINGER HEIDELBERG, TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2019)
    Using currently available infrastructure in pervasive environments it is possible to provide intelligent mechanisms that offer people help and guidance for organizing their daily activities. In this study, a framework ...
  • Kucukyilmaz, Tayfun; Kiziloz, Hakan Ezgi (PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2017)
    Evolutionary algorithms have been reported to be efficient metaheuristics for the optimization of several NP Hard combinatorial optimization problems. In addition to their ability to solve difficult and complex problems ...
  • Evrendilek, Cem; Genc, Burkay; Hnich, Brahim (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2014)
    We address the problem of covering points with orthogonal polygons. Specifically, given a set of n points in the plane, we investigate the existence of an orthogonal polygon such that there is a one-to-one correspondence ...
  • Urgen, Burcu A.; Pehlivan, Selen; Saygin, Ayse P. (PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2019)
    Visual processing of actions is supported by a network consisting of occipito-temporal, parietal, and premotor regions in the human brain, known as the Action Observation Network (AON). In the present study, we investigate ...
  • Dokeroglu, Tansel; Sevinc, Ender (PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2019)
    This study proposes an Island Parallel Evolutionary Extreme Learning Machine algorithm (WE-ELM) for the well-known data classification problem. The ELM is a fast and efficient machine learning technique with its single ...
  • Celikcan, Ufuk; Yaz, Ilker O.; Capin, Tolga (WILEY-BLACKWELL, 111 RIVER ST, HOBOKEN 07030-5774, NJ USA, 2015)
    We present a novel method for retargeting human motion to arbitrary 3D mesh models with as little user interaction as possible. Traditional motion-retargeting systems try to preserve the original motion, while satisfying ...
  • Gebser, Martin; Obermeier, Philipp; Otto, Thomas; Schaub, Torsten; Sabuncu, Orkunt; Nguyen, Van; Son, Tran Cao (CAMBRIDGE UNIV PRESS, 32 AVENUE OF THE AMERICAS, NEW YORK, NY 10013-2473 USA, 2018)
    We introduce the asprilo(1) framework to facilitate experimental studies of approaches addressing complex dynamic applications. For this purpose, we have chosen the domain of robotic intralogistics. This domain is not only ...
  • Yildiz, Z.C.; Capin, Tolga (VISIGRAPP 2019 - Proceedings of the 14th International Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications, 2019)
    3D mesh models are exposed to several geometric operations such as simplification and compression. Several metrics for evaluating the perceived quality of 3D meshes have already been developed. However, most of these metrics ...
  • Yildiz, H.U.; Gungor, V.C.; Tavli, B. (Institute of Electrical and Electronics Engineers Inc., 2018)
    In smart grid applications, Wireless Sensor Net-works (WSNs) which consist of battery limited sensor nodes are used on critical equipments of power distribution grids for monitoring purposes. WSN nodes have tight energy ...
  • Celikcan, Ufuk; Arpa, Sami; Capin, Tolga (SPRINGER LONDON LTD, 236 GRAYS INN RD, 6TH FLOOR, LONDON WC1X 8HL, ENGLAND, 2017)
    We introduce an image reproduction model that retargets colors for printing purposes to ensure similar luminance perception under photopic and scotopic vision. Our model is based on the physiological functioning of the rod ...
  • Alparslan, Onur; Gunes, Onur; Hanay, Y. Sinan; Arakawa, Shin'ichi; Murata, Masayuki (IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2017)
    We propose an architecture that increases the resiliency against DDoS attacks by leveraging virtual network functions (VNF) and software defined networking (SDN). In the first step, the proposed architecture places the ...
  • Altinoz, O. Tolga; Mengusoglu, Erhan (IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2015)
    The long term electricity demand forecasting is evaluated by using past demand and weather data. The aim of this study is to present the effect of the variety of inputs on performance. Therefore neural network models are ...
  • Yildiz, Z.C.; Oztireli, A.C.; Capin, T. (Springer Verlag, 2018)
    To decide whether the perceived quality of a mesh is influenced by a certain modification such as compression or simplification, a metric for estimating the visual quality of 3D meshes is required. Today, machine learning ...
  • Kucukyilmaz, Tayfun; Cambazoglu, B. Barla; Aykanat, Cevdet; Baeza-Yates, Ricardo (ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2017)
