Dynamical system analysis of Myrzakulov gravity

چکیده

We perform a dynamical system analysis of Myrzakulov or $F(R,T)$ gravity, which is subclass affinely connected metric theories, where ones uses specific but nonspecial connection that allows for nonzero curvature and torsion simultaneously. consider two classes models, extract the critical points, examine their stability properties alongside physical features. In class 1 possess $\mathrm{\ensuremath{\Lambda}}$ cold dark matter (CDM) cosmology as limit, we find sequence energy eras, show Universe will result in dark-energy-dominated point behaves like cosmological constant. Concerning equation-of-state parameter, it lies quintessence phantom regime, according to value model parameter. For 2 again dark-energy-dominated, de Sitter late-time attractor, although scenario does not $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$ limit. The behavior richer, sector can be quintessencelike, phantomlike, experience phantom-divide crossing during evolution.

DYNAMICAL ANALYSIS AND DESIGN OF FRONT ENGINE ACCESSORY DRIVE SYSTEM

In this paper, Front Engine Accessory Drive (FEAD) system of automotive engine is modeled with ADAMS software. The model is validated using engine test data. It is then used to investigate the effect of design parameters on the system performance such as belt vibration and loads on the idlers. Three alternative layouts were developed in order to improve the performance of original EEAD system. ...

Bifurcation analysis and dynamics of a Lorenz –type dynamical system 

./files/site1/files/0Abstract1.pdfIn this paper we consider a continues Lorenz – type dynamical system. Dynamical behaviors of this system such as computing equilibrium points, different bifurcation curves and computation of normal form coefficient of each bifurcation point analytically and numerically. In particular we derived sufficient conditions for existence of Hopf and Pitchfork bifurcati...

Dynamical Localization of Gravity

We dynamically construct Randall-Sundrum brane localized gravity from a 5-dimensional bulk scalar soliton field obeying a sine-Gordon equation, with the discrete brane Z2 symmetry arising from the discrete symmetry of the potential, and with the Minkowski brane Randall-Sundrum relation between bulk and brane cosmological constants being obtained naturally without any fine tuning. Additionally, ...
