    • An approximation algorithm for computing the visibility region of a point on a terrain and visibility testing 

      Alipour, S.; Ghodsi, M.; Güdükbay, Uğur; Golkari, M. (IEEE, 2014-01)
      Given a terrain and a query point p on or above it, we want to count the number of triangles of terrain that are visible from p. We present an approximation algorithm to solve this problem. We implement the algorithm and ...
    • Dipole source reconstruction of brain signals by using particle swarm optimization 

      Alp, Y.K.; Arikan, O.; Karakaş, S. (2009)
      Resolving the sources of neural activity is of prime importance in the analysis of Event Related Potentials (ERP). These sources can be modeled as effective dipoles. Identifying the dipole parameters from the measured ...
    • ERP source reconstruction by using Particle Swarm Optimization 

      Alp, Y.K.; Arikan, O.; Karakas, S. (2009)
      Localization of the sources of Event Related Potentials (ERP) is a challenging inverse problem, especially to resolve sources of neural activity occurring simultaneously. By using an effective dipole source model, we propose ...
    • Preventing unauthorized data flows 

      Uzun, E.; Parlato, G.; Atluri, V.; Ferrara, A. L.; Vaidya, J.; Sural, S.; Lorenzi, D. (Springer Verlag, 2017)
      Trojan Horse attacks can lead to unauthorized data flows and can cause either a confidentiality violation or an integrity violation. Existing solutions to address this problem employ analysis techniques that keep track of ...
    • Selective replicated declustering for arbitrary queries 

      Oktay, K.Y.; Turk, A.; Aykanat, C. (2009)
      Data declustering is used to minimize query response times in data intensive applications. In this technique, query retrieval process is parallelized by distributing the data among several disks and it is useful in ...
