Experimental Correlations for the Performance and Aperture Selection of Wire Wrapped Screens in Steam Assisted Gravity Drainage Production Wells
Download2020-08-01
Jesus David Montero Pallares, Chenxi Wang, Mohammad Haftani, Alireza Nouri
Wire-wrapped screens (WWSs) are one of the most-commonly used devices by steam-assisted gravity drainage (SAGD) operators because of the capacity to control plugging and improve flow performance. WWSs offer high open-to-flow area (OFA) (6 to 18%) that allow a high release of fines, hence, less...

In this study, a surrogate of Cryptosporidium parvum oocysts was prepared using Cryptosporidium-sized carboxylated polystyrene microspheres and an alpha-1-acid glycoprotein (AGP). The zeta potential of the modified surrogates was found to be similar to that of viable Cryptosporidium parvum. These...

Framework for Identification of Factors Affecting Construction Crew Motivation and Performance
Download2018-01-01
Raoufi, Mohammad, Fayek, Aminah Robinson
Construction researchers have long had difficulties identifying motivational factors and situational and contextual factors affecting crew motivation and performance. The two main objectives of this paper are to define a methodology to identify the factors affecting construction crew motivation...

Raoufi, Mohammad, Fayek, Aminah Robinson
Recently, agent-based modeling (ABM) has been used to model construction processes and practices because it is capable of handling some of the complexities that arise from the interactions of system components. However, ABM alone cannot take into account the subjective uncertainty that exists in...

Fuzzy Agent-Based Multicriteria Decision-Making Model for Analyzing Construction Crew Performance
Download2020-01-01
Kedir, Nebiyu Siraj, Raoufi, Mohammad, Fayek, Aminah Robinson
Selecting economically feasible policies for maximizing crew motivation and performance is a multifaceted problem, and each aspect of the process poses considerable unique challenges for construction practitioners. Fuzzy agent-based modeling (FABM) addresses some of the challenges of predicting...
