this is the first attempt at process modeling in terms of predictive control using a hierachical method based on regression analysis and artificial neural networks (anns). this hierachical method leads to the reliability improvement of neural model of the process in predicting (extrapolation and interpolation) the process output. such an outlook makes it possible to predict the proper input set...

accurate permeability estimation has always been a concern in determining flow units, assigning appropriate capillary pressure andrelative permeability curves to reservoir rock types, geological modeling, and dynamic simulation.acoustic method can be used as analternative and effective tool for permeability determination. in this study, a four-step approach is proposed for permeability estimati...

this research study employed a mixed-methods approach to investigate the test takers’ perceptions and anx- iety in relation to an english language proficiency test called community english program (cep). this study also evaluated the direct and semi-direct modes for speaking module of this test. to this end, 300 eng- lish as foreign language (efl) students were recruited in the study as test ta...

From a mobility rationale, advanced air (AAM) and/or urban (UAM) claims reduction in travel time with integration into intermodal transportation networks and ground traffic congestion due to the current modal shift air, ultimately contributing more sustainable transportation. Starting 2025, South Korea is planning operate taxis between International Airport Seoul downtown. This study applied mi...

This article presents a fuzzy robust Mixed - Sensitivity Gain - Scheduled H controller based on the Loop -Shaping methodology for a class of MIMO uncertain nonlinear Time - Varying systems. In order to design this controller, the nonlinear parameter - dependent plant is first modeled as a set of linear subsystems by Takagi and Sugeno’s (T - S) fuzzy approach. Both Loop - Shaping methodology and...
