Tachyon logamediate inflation on the brane

According to a Barrow solution for the scale factor of the universe, the main properties of the tachyon inflation model in the framework of the RSII braneworld are studied. Within this framework the basic slow-roll parameters are calculated analytically. We compare this inflationary scenario to the latest observational data. The predicted spectral index and the tensor-to-scalar ...

Tachyon warm-intermediate inflation in the light of Planck data

We study the main properties of the warm tachyon inflation model in the framework of the RSII braneworld based on Barrow’s solution for the scale factor of the universe. Within this framework we calculate analytically the basic slow-roll parameters for different versions of warm inflation. We test the performance of this inflationary scenario against the latest observational data ...

Development of an intelligent model for wax deposition in oil pipeline

Crude oil transport is one important part of the oil industry. Wax deposition is a very complex phenomenon that in recent years is one of the major challenges in oil industry. Wax deposited on the inner surface of crude oil pipelines are capable to reduce or completely stop the oil flow and the oil industry imposing large costs. The main objective of this study was to present a ...

Twofold Hidden Conformal Symmetry of Kerr-Bolt-AdS-dS Black Holes

We extend the recent proposal of twofold hidden conformal symmetry to the four-dimensional Kerr-Bolt-AdS-dS black holes. The J-picture of holographic description of Kerr-Bolt-AdS-dS black holes previously has been studied in the paper [B. Chen, A. M. Ghezelbash, V. Kamali, M. R. Setare, arXiv:1009.1497]. Here we present a new description, in view of the NUT charge of black hole. We ...
