In this work we will combine two important notions for the argumentation community into Abstract Argumentation Frameworks (AFs). These notions correspond to Toulmin’s backings and Pollock’s undercutting defeaters. We will define Backing-Undercutting Argumentation Frameworks (BUAFs), an extension of AFs that includes a specialized support relation, a distinction between different attack types, a...

in this research, the coupling between non-gray radiation and separation convection flow in a duct is investigated numerically. distributions of absorption coefficients across the spectrum  are obtained from the hitran2008 database. the full-spectrum k-distribution method is used to deal with the non-gray part of the problem, while the gray radiation calculations are performed using the planck ...

Backward-facing step (BFS) is a model that provides several applicative features in engineering. The complex phenomena of BFS flow have crucial impact on any application. Therefore, this study comprehensively investigates the characteristics with various shapes. backward-facing (F-BFS) fillets were tested at intervals Reynolds number 50 smaller than Re 400 using CFD approach. Based computationa...

Flow topology and unsteady cavitation dynamics in the wake of a backward facing step was investigated using high speed videography time-resolved X-ray densitometry, along with static dynamic pressure measurements. The measurements are used to inform understanding underlying mechanisms observed flow as they related shock wave induced instabilities. differences cavity behavior at different number...
