Artificial Intelligence Frameworks for Sentiment Variations’ Reasoning and Emerging Topic Detection
منشور في 2021"…This thesis contributes to the very few studies that took one step ahead by developing novel models to understand what causes sentiment changes over time. Obviously, identifying main reasons for public reactions is valuable to decision-makers so that they can take necessary actions in a timely manner. …"

Morphological changes in amblyopic eyes in choriocapillaris and Sattler’s layer in comparison to healthy eyes, and in retinal nerve fiber layer in comparison to fellow eyes through...
منشور في 2021"…Results The method of measuring reflectivity is good to excellent reliability for all regions of interest except the fourth. The mean reflectivity of the choriocapillaris and Sattler’s layer in amblyopic eyes were significantly lower than in healthy eyes (p = 0.003 and p = 0.008 respectively). …"

Charge carrier mobility in hybrid halide perovskites
منشور في 2015"…<p dir="ltr">The charge transport properties of hybrid halide perovskites are investigated with a combination of density functional theory including van der Waals interaction and the Boltzmann theory for diffusive transport in the relaxation time approximation. We find the mobility of electrons to be in the range 5–10 cm<sup>2</sup>V−<sup>1</sup>s−<sup>1</sup> and that for holes within 1–5 cm<sup>2</sup>V−<sup>1</sup>s−<sup>1</sup>, where the variations depend on the crystal structure investigated and the level of doping. …"
