    Anticipatory effect of execution on observation: an approach using ExoPinch finger robot
    (Tubitak Scientific & Technological Research Council Turkey, 2019) Arıkan, Kutluk Bilge; Zadeh, Hassan Gol Mohammad; Turgut, Ali Emre; Zinnuroğlu, Murat; Bayer, Gözde; Günendi, Zafer; Cengiz, Bülent; Department of Mechatronics Engineering
    Background/aim: This study aims to explore the mirror neuron system (MNS) involvement using mu (8–12 Hz)/beta (15–25 Hz) bandsuppression in an action observation-execution paradigm.Materials and methods: Electrophysiological (EEG) data from 16 electrodes were recorded while 8 participants observed video clips ofa hand squeezing a spring. Specifically, the effect of anticipated execution on observation was studied. For this purpose, a fully actuatedfinger exoskeleton robot was utilized to synchronize observation and execution and to control the execution condition for the participants. Anticipatory effect was created with a randomized robot accompany session.Results: The results showed that the observational condition (with or without anticipation) interacted with hemisphere at central channels near somatosensory cortex. Additionally, we explored the response of MNS on the kinetics features of visual stimuli (hard or softspring).Conclusion: The results showed an interaction effect of kinetics features and hemisphere at frontal channels corresponding nearly tothe ventral premotor cortex area of the brain. The activation of mirror neurons in this area plays a crucial role in observational learning.Based on our results, we propose that specific type of visual stimuli can be combined with the functional abilities of the MNS in the action observation based treatment of hand motor dysfunction of stroke patients to have a positive additional impact.

    Araç dinamiğinin tek izli araç modeli yardımıyla tanılanması
    (2004) Arıkan, Kutluk Bilge; Ünlüsoy, Y. Samim; Department of Mechatronics Engineering
    Tek izli araç modeli yapısı kullanılarak, aracın dönüş dinamiğini anlatan matematiksel modeller tanılanmıştır. ARMAX ve durum uzayı modelleri parametre kestirimlerinde kullanılmıştır. Öngörü hatası kestir imi yöntemi uygulanmıştır. Kestirilen modellerden tek izli araç modelini oluşturan fiziksel parametreler de hesaplanmıştır.
