Development of a global road safety performance function using deep neural networks
(Elsevier, 2017-08-01)This paper explores the idea of applying a machine learning approach to develop a global road safety performance function (SFP) that can be used to predict the expected crash frequencies of different highways from different ... -
Impact Assessment of Construction Supply Chain Risk Changes on Project Time and Cost
(University of Waterloo, 2017-09-11)The supply chain plays a key role in the construction industry. The importance of the Construction Supply Chain (CSC) is not less than that of the onsite construction phases. There are many risk factors that influence ... -
Comparison of the Impacts of Thermal Pretreatment on Waste Activated Sludge using Aerobic and Anaerobic Digestion
(University of Waterloo, 2017-08-31)Thermal pretreatment systems are typically employed to improve waste-activated sludge (WAS) dewaterability and to treat sludge prior to anaerobic digestion. It is important to understand how WAS properties are affected ... -
Bond of Corroded Reinforcement in Partial Depth Repairs in Reinforced Concrete Elements
(University of Waterloo, 2017-08-29)The bond in a reinforcement concrete (RC) structure is represented by the force transfer between the reinforcing bar and the surrounding concrete. All the RC structures are designed to have a perfect bond between the ... -
Electrogeneration of hydrogen peroxide for applications in water/wastewater treatment
(University of Waterloo, 2017-08-29)Hydrogen peroxide (H2O2) is an effective, environmentally friendly oxidant used directly and in advanced oxidation processes for water and wastewater treatment. Although most H2O2 is currently manufactured offsite, ... -
Enhanced Traffic Signal Operation using Connected Vehicle Data
(University of Waterloo, 2017-08-29)As traffic on urban road network increases, congestion and delays are becoming more severe. At grade intersections form capacity bottlenecks in urban road networks because at these locations, capacity must be shared by ... -
Technical and Economic Assessment of Ground Source Heat Pump Systems (GSHPs) in Ontario
(University of Waterloo, 2017-08-28)Ground Source Heat Pump Systems (GSHPs) are one of the most promising clean and low-carbon source of geothermal renewable energy technologies for heating, ventilation and cooling of homes. Geothermal heat pump (GHP) ... -
Improving the Fiscal Transparency and Sustainability of Public-Sector Transportation Infrastructure
(University of Waterloo, 2017-08-25)Public-sector infrastructure funding is a complex and often unclear process. Cities operate most efficiently if there is an adequately-funded transportation network with which residents and visitors can easily travel from ... -
Impact of Free Transit Passes on Youth Travel Behaviour
(University of Waterloo, 2017-08-24)Young adults are often restricted in their activity participation and mobility by parental constraints and driving age restrictions. Public transit can, however, be a viable option for youth to accomplish their trips ... -
Treatment of the Cyanotoxins Cylindrospermopsin, Microcystin-LR, and Anatoxin-a by Activated Carbon in Drinking Water
(University of Waterloo, 2017-08-23)Cyanotoxins are known to cause human and animal illness, in some cases resulting in death, and their presence in drinking water is a potential risk to public health. Cylindrospermopsin (CYL), microcystin-LR (MC-LR), and ... -
Tests on GFRP Reinforced Concrete Knee-Joints Subjected to Negative Moments
(University of Waterloo, 2017-08-22)The use of glass-fibre reinforced polymers as main reinforcement in concrete structures has become an appealing option for structures in aggressive environments. Concrete knee-joints are joints where the beam and column ... -
Impacts of Hydromodification and Sediment Supply Alterations on Bedload Transport and Bed Morphology in Urbanizing Gravel-bed Rivers
(University of Waterloo, 2017-08-18)Urbanization is known to change the hydrologic and sediment supply regimes of rivers, causing more frequent, flashier flood events (hydromodification) and a reduction and redistribution of sediment sources. Presently, the ... -
Construction Scene Point Cloud Acquisition, Object Finding and Clutter Removal in Real Time
(University of Waterloo, 2017-08-15)Within industrial construction, piping can constitute up to 50% of the cost of a typical project. It has been shown that across the activities involved in pipe fabrication, pipe fitting has the highest impact on the critical ... -
Evaluation and Calibration of Pedestrian Bridge Standards for Vibration Serviceability
(University of Waterloo, 2017-08-14)An increase in the use of lightweight materials and emphasis on architecturally appealing designs has resulted in lively pedestrian bridges. A prominent example for this is the serviceability failure of the London Millenium ... -
Bayesian Nonparametric Dirichlet Process Mixture Modeling in Transportation Safety Studies
(University of Waterloo, 2017-08-08)In transportation safety studies, it is often necessary to account for unobserved heterogeneity and multimodality in data. The commonly used standard generalized linear models (e.g., Poisson-gamma models) do not fully ... -
Dislocation Dynamics for High Strain-Rate Plasticity: Inertial and Thermal Effects
(University of Waterloo, 2017-07-26)There has been a trend of miniaturization in recent technological advances, particularly through the development of microelectromechanical systems (MEMS). To cope with the demand for increasing performance from ever smaller ... -
Condition Assessment of Concrete Elements through Two Nondestructive Ultrasonic Techniques
(University of Waterloo, 2017-07-13)Reinforced concrete is one of the materials most used in civil infrastructure, and the expected service life is generally for several decades. However, as any other material, concrete performance is affected by environmental ... -
A Finite Element Investigation of Possible Mechanisms of Luminal Cell Escape from the Mammary Duct: An Initial Step in Breast Cancer Metastasis
(University of Waterloo, 2017-06-14)Cancer is an illness that kills some ten million people every year, and as cancer rates increase, a cure for metastatic disease is more necessary than ever. Breast cancer is the most common form of malignancy in the female ... -
