© 2017 L&H Scientific Publishing, LLC.An oscillator which impacts against a rigid barrier is taken into account. A cycle with zero impact velocity is discussed. The main result of this article concerns stability of the grazing cycle. A significant attention to a model with the variable coefficient of restitution depending on velocity is paid. The mechanical reasons for that are provided as well as new theo- retical advantages have been discovered for the investigation of dynamics near a grazing cycle. The W-map which reduces the system with variable moments of impacts to that with fixed moments and simplifies the analy- sis, is defined. A new type of linearization system with two compounds is applied to investigate the stability of the grazing cycle whose existence is easily examined. A new approach to suppress a singularity, caused by the tangency, in linearization has been developed. Simulations are provided to visualize the stability of the grazing cycle.

Stability in non-autonomous periodic systems with grazing stationary impacts Akhmet, Marat (2017-01-01) This paper examines impulsive non-autonomous periodic systems whose surfaces of discontinuity and impact functions are not depending on the time variable. The W-map which alters the system with variable moments of impulses to that with fixed moments and facilitates the investigations, is presented. A particular linearizion system with two compartments is utilized to analyze stability of a grazing periodic solution. A significant way to keep down a singularity in linearizion is demonstrated. A concise review...
Modeling of reversible γ/α transformations of low carbon steels in the intercritical temperature range Reti, Tamas; Felde, Imre; Gür, Cemil Hakan (2004-10-01) A phenomenological kinetic model has been developed for the prediction of non-isothermal reversible incomplete transformations in low-carbon hypoeutectoid steels. The theoretical basis of the proposed method has its origin in a possible extension of the traditional Austin-Rickett kinetic differential equation. To critically assess the applicability of the model, a number of experiments based on computer simulations have been performed to predict the austenite/ferrite proeutectoid transformation in the tempe...
Full Anelastic Waveform Tomography Including Model Uncertainty Askan Gündoğan, Ayşegül (2008-12-01) This article is concerned with the problem of seismic inversion in the presence of model uncertainty. In a recent article (Askan et al., 2007), we described an inverse adjoint anelastic wave propagation algorithm for determining the crustal velocity and attenuation properties of basins in earthquake-prone regions. We formulated the tomography problem as a constrained optimization problem where the constraints are the partial and the ordinary differential equations that govern the anelastic wave propagation ...
An observational study of the precedence effect Hacıhabiboğlu, Hüseyin (2006-05-01) This paper proposes a framework model for the analysis of sound source localisation under the precedence effect using Gaussian mixtures. The model quantifies the effect of the lagging sound over the angular position and the width of the perceived auditory event, and incorporates some well-known aspects of the precedence effect in a single framework. Two sound source localisation experiments were carried out in order to show the utility of the proposed model. In the first experiment, the localisation accurac...
A computer simulation of void dynamics under the action of electromigration and capillary forces in narrow thin interconnects Ogurtani, TO; Oren, EE (2000-10-25) In these studies a comprehensive picture of void dynamics in connection with the critical morphological evaluation has been thoroughly anticipated in order to understand main reasons as well as the conditions under which premature failure of metallic thin interconnects occur. Our mathematical model on diffusion and mass accumulation on void surfaces, under the action of applied electrostatic potential and capillary effects, follows a novel irreversible but discrete thermodynamic formulation of interphases a...
