Yayın Neural network steering control algorithm for autonomous ground vehicles having signal time delay(SAGE Publications Ltd, 2024-03) Dinçmen, ErkinAn adaptive neural network–based steering control algorithm is proposed for yaw rate tracking of autonomous ground vehicles with in-vehicle signal time delay. The control system consists of two neural networks: the observer neural network and the controller neural network. The observer neural network adapts itself to the system dynamics during the training phase. Once trained, the observer neural network cooperates with the controller neural network, which constantly adapts itself during the control task. In this way, an adaptive and intelligent control structure is proposed. Through simulation studies, it has been shown that while a proportional-integral-derivative type steering controller fails to perform its control task in case of steering signal delay, the proposed control algorithm manages to adapt itself according to the control problem and achieves reference yaw rate tracking. The robustness of the control algorithm according to the signal delay magnitude has been demonstrated by simulation studies. A rigorous Lyapunov stability analysis of the control algorithm is also presented.Yayın A mean field model near the NAC point in liquid crystals(Physical Soc Republic China, 2002-10) Enginer, Yücel; Salihoğlu, Selami; Yurtseven, HamitIn this study we obtain the phase line equations for the nematic-smectic A (NA), smectic A-smectic C (AC) and nematic-smectic C (NC) transitions using a mean field model. We fit these phase line equations to the experimental phase diagram near the Nenatic-smectic A-smectic C (NAC) point. Our calculated phase diagram agrees well with the experimental.Yayın The mediating role of schema modes in the relationship between parentification and codependency(SAGE Publications Inc., 2025-07) Ünver, Buket; Önürme, Güneş BeyzaThe aim of this study is to examine the mediating role of schema modes between parentification in different roles and codependency. The sample of the study consists of 599 Turkish women aged between 18 and 64. Firstly, Pearson correlation analysis was conducted, revealing that most of the variables were significantly correlated. Secondly, mediating analysis was performed. The results showed that vulnerable child, angry child, compliant surrender, and demanding parent modes mediated the relationship between parent-focused parentification and codependency. The relationship between sibling-focused parentification and codependency was found to be mediated by the happy child, punitive parent, and demanding parent mode. These findings indicate that parentification in different roles are associated with codependency in women through distinct schema modes, with the exception of the demanding parent mode, which appeared in both paths. Furthermore, the results highlight that disruptions in the hierarchical structure of the early parent-child relationship shapes emotional and cognitive structures in adulthood, potentially contributing to the development of dysfunctional relationship dynamics.
