به‌منظور تحلیل نوترونیک قلب رآکتورها، نیاز به توسعه نرم‌افزارهای محاسبات هسته‌ای جهت تولید ثابت‌های چند گروهی و حل عددی معادله پخش است. برای این منظور، از روش‌هایی استفاده می‌شود که علاوه بر دقت مناسب حجم زمان بهینه‌ای برخوردار باشند. در پژوهش تئوری حاکم روش نودال بسط شار جریان متوسط هم‌چنین مرتبه‌های بالاتر پرداخته می‌شود. پس‌ازآن با گسسته‌سازی نوترون، نشان داده روش‌ بهینه خوبی بهره می‌برد. مس...

In late medieval and early modern times, books, as well the people who produced read (or listened to) them, moved between regions, social circles, languages with relative ease. Yet, in multilingual Low Countries, francophone literature was both internationally mobile firmly rooted local soil. The five contributions collected this volume demonstrate that while general issues of ‘otherness’ were ...

In the literature, the generalized Bouc-Wen model can track precisely asymmetric hysteresis nonlinearity. In this paper, we propose to extend this generalized model to multivariable hysteresis model that can track the nonlinearities in multi-degrees of freedom (multi-DoF) hysteretic actuated systems. In particular, these systems are typified by strong hysteresis couplings. Then, a method of ide...

The problem Wiener systems identification is addressed in presence of hysteresis nonlinearities, presently described by the Bouc-Wen model. The latter is nonlinear differential equation involving unknown parameters, some of which coming in nonlinearly. Except for stability, the linear subsystem is arbitrary and, in particular, it is not given a particular structure. By using sine excitations, t...

The Bouc–Wen nonlinear hysteretic model has many control parameters, which been widely used in the field of seismic isolation. isolation layer is most important part system, can be effectively simulated by model, and system reflect different dynamic characteristics under parameters. Therefore, this paper mainly studies analyzes influence factors based on incremental harmonic balance method, pro...

Abstract. This paper presents a reduced model to describe the nonlinear dynamic behavior of Stockbridge dampers. The proposed is based on classic Bouc-Wen hysteretic law and requires identification small number parameters. formulation used within an extended version Energy Balance Method assess role damper nonlinearities in mitigating aeolian vibrations reference overhead transmission line.
