    • Classification Of Imaginary Movements In ECoG With A Hybrid Approach Based On Multi-dimensional Hilbert-SVM Solution 

      Demirer, R. Murat; Özerdem, Mehmet S.; Bayrak, Coşkun (Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2009-03-30)
      The study presented in this paper shows that electrocorticographic (ECoG) signals can be classified for making use of a human brain-computer interface (BCI) field. The results show that certain invariant phase transition ...

    • Determination of ECoG Information Flow Activity Based on Granger Causality and Hilbert Transformation 

      Demirer, Rüştü Murat; Özerdem, Mehmet Sıraç; Bayrak, Coşkun; Mendi, Şekip Engin (Elsevier Ireland Ltd, Elsevıer House, Brookvale Plaza, East Park Shannon, Co, Clare, 00000, Ireland, 2013-12)
      Analysis of directional information flow patterns among different regions of the brain is important for investigating the relation between ECoG (electrocorticographic) and mental activity. The objective is to study and ...
    • Enable Delegation For RBAC With Secure Authorization Certificate 

      Zhou, GuangXu; Demirer, Murat; Bayrak, Coşkun; Wang, Licheng (Elsevier Advanced Technology, Oxford Fulfillment Centre The Boulevard, Langford Lane, Kidlington, Oxford Ox5 1Gb, Oxon, England, 2011-11)
      Our motivation in this paper is to explore a Secure Delegation Scheme that could keep access control information hidden through network transmission. This approach introduces the quasirandom structure, 3-Uniform Hypergraph, ...
    • Food Intake Monitoring System for Mobile Devices 

      Mendi, Şekip Engin; Özyavuz, Öcal; Pekesen, Emrah; Bayrak, Coşkun (IEEE, 345 E 47Th St, New York, Ny 10017 Usa, 2013)
      In this paper, we introduce a real-time food intake monitoring system for mobile devices. The proposed system gets acceleration data from the sensor placed on the wrist of the user during a meal. The data is then sent to ...
