The Level of Traffic Stress (LTS) framework is widely used to assess the suitability of roadway environments for cycling. Its main strength is the identification of infrastructure characteristics that meet the needs of different cyclist groups. The four levels of infrastructure ratings, LTS 1 to...

An Improved Set of Design Criteria for Slotted Liners in Steam Assisted Gravity Drainage Operation
Download2020-01-01
Chenxi Wang, Mohammad Haftani, Jesus David Montero Pallares, Alireza Nouri
Slotted liners are widely used in steam-assisted gravity drainage (SAGD) wells to control sand production and sustain wellbore productivity. The slotted liner can provide desirable performance when appropriately designed. A literature review indicates a limited number of studies that offer design...

Assessment of Intended Electric Vehicle Usage and Travel Behaviour during Wildfire Evacuations
Download2025-01-22
Babaei, Mohammad Hossein, Wong, Stephen D.
The rise in the adoption of electric vehicles (EVs) presents a unique challenge for disaster planning. Their reliance upon the grid for fuel requires capable and resilient electricity infrastructure to withstand the surge in demand during evacuation scenarios. This grid resilience is crucial for...

Woldeyohannes Yirgo, Kaleab, Kim, Amy M.
Consolidated air services at hub airports in the U.S. encourage passenger leakage. Compared to smaller airports, trips from large hub airports consume less fuel per passenger-kilometer. Trips from large hubs also result in less pollutants per passenger-kilometer. Attractive air services at large...

Before-and-after empirical Bayes evaluation of automated mobile speed enforcement on urban arterial roads
Download2019-11-12
Li, R., El-Basyouny, K., Kim, A.
Speeding is a leading factor in road collisions and is found to contribute to approximately one third of fatal collisions. Speed enforcement is one of the most common countermeasures used to reduce speed. However, a gap exists in the literature regarding the effectiveness of automated mobile...

Mojtaba Rahimi, Dave Chan, Alireza Nouri
This paper presents a critical state constitutive model for cemented sand. The model uses a single capped yield surface as a function of the void ratio, confining pressure, preconsolidation pressure, and stress ratio at the peak of the undrained effective stress path. To model the cemented...

Comparison of the transport and deposition of Pseudomonas aeruginosa under aerobic and anaerobic conditions
Comparison of the transport and deposition of Pseudomonas aeruginosa under aerobic and anaerobic conditions
Download2016-01-01
Huixin Zhang, Hongbo Zeng, Ania C. Ulrich, Yang Liu
Laboratory-scale columns were employed to study the effect of oxygen and ionic strength on the transport of Pseudomonas aeruginosa PAO1 in porous media. In anaerobic experiments, cells were grown and transport experiments were conducted in a well-controlled anaerobic chamber. Cell surface...

Mojtaba Rahimi, Dave Chan, Alireza Nouri
This paper presents a constitutive model for describing the stress-strain response of sands under cyclic loading. The model, formulated using the critical state theory within the bounding surface plasticity framework, is an upgraded version of an existing model developed for monotonic behavior...
