Fatigue failure is one of the most common failure modes in steel structures when subjected to variable or repeated loading. Involving repeated loading, moving, and unloading containers, the quayside ship-to-shore cranes are prone to develop fatigue-induced cracks. Non-destructive inspection methods are mostly used in port cranes to detect fatigue-induced cracks. However, the methods have uncertainties […]

Rural Municipality of St. François Xavier developed a strategy to lower total phosphorus level below legal water discharge limits when over-limit phosphorus values are measured at the discharge pipe of the lagoon. This strategy consists of a trickled discharge of lagoon treated water and a swale system. Swales are widely applied to manage surface runoffs […]

Coronaviruses are a large family of viruses and COVID-19 is a new disease from this family that has not been previously identified in humans [1]. Those who are infected with COVID-19 may have little to no symptoms and may take up to 14 days to appear after exposure to COVID-19 [2]. It’s possible to detect […]

Alberta oil sands mining operations have produced about 1 billion m3 of fluid fine tailings (FFT) stored in large “ponds” up to 10 km long and 4 km wide. FFT is a stable colloidal suspension that is forecasted to take decades to dewater if left undisturbed. The EKS-DT process, developed by ElectroKinetic Solutions, has the […]

Poly- and perfluoroalkyl substances (PFASs) are groups of contaminants that have received much attention due to their frequent detection in the environment and potential adverse health effect on humans and animals. PFASs can be removed from water using adsorption processes. Adsorbent produced by pyrolysis of sewage sludge (SBAC) offers a promising sustainable solution for removing […]

Concrete bridge decks have joints, which are created because of the method used to build a bridge structure. These joints allow water and other deleterious materials to pass through the bridge deck corroding the deck and the supporting girders. Link slabs are provided to conceal these joints. A link slab is a thin slab made […]

The proposed project aims to apply artificial intelligence methods to augment in-place non-destructive testing technologies in order to reduce or eliminate the need for intrusive methods (i.e. concrete core extraction) for concrete strength estimation. The proposed approach is based on the SonReb method, which combines two non-destructive testing technologies, namely ultrasonic pulse velocity and rebound […]

Currently, the design method of haul road pavements cannot address the rolling resistance under the effects of stabilizers in pavement design. To address this, the overall objective of this research is to develop a new design approach using finite element modeling for mine haul road pavements with stabilized layers. In particular, the prediction of rolling […]

This project aims to develop a retail demand forecasting model that can both handle the long-term and short-term forecasting, and adjust its parameters as more data come in. General long-term prediction models are relatively precise because the context often remains same over time, but can not quickly adapt to unforeseen events, like the global pandemics. […]

To mitigate risks of global malnutrition, hunger, and conflict; food production should become more efficient and sustainable. Controlled Environment Agriculture (CEA) can produce higher yields at reduced spatial and environmental footprints. This control improves management of key elements like water, nutrients, and nutritional outcomes. These advantages come with a cost however; of which energy is […]

…with bonded and unbonded prestressed carbon fiber reinforced polymer (CFRP) plates. The overall objective of this project is to enhance the strengthening efficiency of prestressed hollow-core slabs (PHCS) by using prestressed CFRP plates. More specifically, this project aims to investigate the behavior of the PHCS elements strengthened with prestressed CFRP plates. The application of the […]

Helical piles are extensively used across Canada in various engineering applications. Current design methods estimate the axial capacity of helical piles using soil strength parameters when site investigation is available. Alternatively, helical piles can be designed from an empirical torque correlation when installation torques are available. However, it will be more valuable to the industry […]
