Ohi, Sabrena Jahan, Kim, Amy M.
This paper explores the application of count models to represent the relationship between flight disruptions and weather. Throughout the world, flights are regularly disrupted by delays at airports and in the terminal airspace, and less frequently by diversions and cancelations. Many delay...

Morteza Roostaei, Alireza Nouri, Vahidoddin Fattahpour, Dave Chan
This paper focuses on the study of proppant transport mechanisms in fractures during frac-packing operation. A multi-module, numerical proppant, reservoir and geomechanics simulator has been developed, which improves the current numerical modeling techniques for proppant transport. The modules...

Deconstructing delay: A non-parametric approach to analyzing delay changes in single server queuing systems
Download2019-11-12
This paper introduces an empirically driven, non-parametric method to isolate and estimate the effects that changes in demand and changes in throughput have on delay – in particular, arrival and departure flight delay at airport runways. Classical queuing model concepts were used to develop a...

Developing a Methodology to Characterize Formation Damage (Pore Plugging) due to Fines Migration in Sand Control Tests
Download2019-01-01
Chenxi Wang, Jesus D. Montero Pallares, Mohammad Haftani, Alireza Nouri
Stand-alone screens (SAS) have been widely used in steam assisted gravity drainage (SAGD) operations. Although many researchers investigated the flow performance of SAS through sand control tests, the formation damage (pore plugging) due to fines migration has not been characterized under...

Developing a risk breakdown matrix for onshore wind farm projects using fuzzy case-based reasoning
Download2021-08-15
Somi, Sahand, Seresht, Nima Gerami, Fayek, Aminah Robinson
As worldwide goals for sustainable development expand, numerous countries are investing in renewable energy projects, particularly onshore and offshore wind farm projects, which have low adverse environmental impacts. Since onshore wind farm projects are novel types of energy infrastructure...

Digitalization Opportunities Road Mapping Tool (DORMT©): A framework to assess digitalization opportunities in construction organizations
Download2021-04-13
Gebretekle, Yisshak Tadesse, Kamau, Daniel Waweru, Raoufi, Mohammad, Fayek, Aminah Robinson
The construction industry is entering the digital age, which offers innovative digitalization opportunities (DOs) regarding cost efficiency, project management, and improved client experience. In their early efforts to implement DOs, construction organizations have had varying degrees of success,...

Yifei Cui, Dave Chan, Alireza Nouri
This paper presents a numerical scheme for a solid–fluid coupled discrete-element method (DEM) that takes into consideration solid deformation and pore pressure generation and dissipation. Analytical solutions of conventional soil mechanics examples obtained by oedometer testing are used to...

Dynamic modeling of multi-factor construction productivity for equipment-intensive activities.
Download2018-07-12
Seresht, Nima Gerami, Fayek, Aminah Robinson
Construction productivity is a major research interest within the construction domain. Because construction is a labor-intensive industry, previous research has often focused on construction labor productivity (CLP). However, equipment is the main driver of productivity for some construction...

Effect of naphtha diluent on greenhouse gases and reduced sulfur compounds emissions from oil sands tailings
Effect of naphtha diluent on greenhouse gases and reduced sulfur compounds emissions from oil sands tailings
Download2017-01-01
Kathleen F. Gee, Ho Yin Poon, Zaher Hashisho, Ania C. Ulrich
The long-term storage of oil sands tailings has resulted in the evolution of greenhouse gases (CH4 and CO2) as a result of residual organics biodegradation. Recent studies have identified black, sulfidic zones belowthe tailingswater interface, which may be producing toxic sulfur-containing gases....
