Enhancing Aspect-based Sentiment Analysis with ParsBERT in Persian Language
Farid Ariai, Maryam Tayefeh Mahmoudi, Ali Moeini
In the era of pervasive internet use and the dominance of social networks, researchers face significant challenges in Persian text mining including the scarcity of adequate dataset…
Numerical Solutions of Heat Diffusion Equation Over One Dimensional Rod Region
Mehran Makhtoumi
Adaptive methods for derivation of analytical and numerical solutions of heat diffusion in one dimensional thin rod have investigated. Comperhensive comparsion analysis based on th…
Unstable modes of non-axisymmetric gaseous discs
Naser M. Asghari, Mir Abbas Jalali
We present a perturbation theory for studying the instabilities of non-axisymmetric gaseous discs. We perturb the dynamical equations of self-gravitating fluids in the vicinity of…
Scale-free equilibria of self-gravitating gaseous disks with flat rotation curves
Mir Abbas Jalali, Mehdi Abolghasemi
We introduce exact analytical solutions of the steady-state hydrodynamic equations of scale-free, self-gravitating gaseous disks with flat rotation curves. We express the velocity…
The curvature condition for self-consistent scale-free galaxies
M. A. Jalali, P. Tim de Zeeuw
We modify the curvature condition for the existence of self-consistent scale-free discs, introduced by Zhao, Carollo & de Zeeuw. We survey the parameter space of the power-law disc…
