  In this paper, we study particle aspects of the φ6 kinks in an external potential. The external potential is implemented by breaking the translational invariance of the system. The dynamics of the kink is calculated for the simple harmonic oscillator (SHO) and barrier potentials. The periodic motion of the kink in the SHO case is compared to the corresponding ordinary (classical) motion. It i...

 In this paper, we calculate nuclear structure function and EMC effect of 40Ca and 56Fe nuclei. To achive the goals, we consider Fermi motion and binding energy contrbiution in the harmonic oscillator model. In this model, harmonic oscillator parameter ħω related to shells root mean square radius and for free nucleon structure functions, is obtained from GRV’s free nucleon structure functions. ...

" استاپ موشن" (stop motion) یا انیمیشن ایست – حرکتی یکی از تکنیک های ساخت انیمیشن که در آن با استفاده از فیلمبرداری فریم به فریم اشیاء فیزیکی را به حرکت در می آورند و از پشت سر هم قراردادن تصاویر این حرکت های فریم به فریم، تصور حرکت القا می شود. "موشن گرافیک" (motion graphic) نیز یکی دیگر از تکنیک های ساخت انیمیشن است. این تکنیک با استفاده از تکنولوژی ویدئو و با ایجاد توهم حرکت یا تغییر در ظاهر...

Abstract   In vibratory systems, linear and nonlinear vibration absorbers can be used to suppress the primary and super-harmonic resonance responses. In this paper, the behavior of a nonlinear system with a nonlinear absorber, under the primary and super-harmonic resonances is investigated. The stiffnesses of the main system and the absorber are cubically nonlinear and the dampers are linear. M...

In this paper we study harmonic functions of subordinate killed Brownian motion in a domain D: We first prove that, when the killed Brownian semigroup in D is intrinsic ultracontractive, all nonnegative harmonic functions of the subordinate killed Brownian motion in D are continuous and then we establish a Harnack inequality for these harmonic functions. We then show that, when D is a bounded L...

The harmonic oscillator is a paradigm of predictability. The resonance response of a harmonic oscillator can be exploited to make clocks accurate to 1 part in 10. Harmonic oscillations are normally observed in systems operating near equilibrium and governed by linear or “Hooke’s law” restoring forces. Nonetheless, for small enough excursions from equilibrium, systems governed by nonlinear resto...
