During interplanetary travels, space radiations are always crucial to spacecraft design due to their extreme hazards to human beings and electronics. Conventional materials, such as aluminum and other heavy metals, have been widely used on spacecraft. The cost of launching overweighed items to space is still high even reusable rockets are available now. Reducing weight […]

Rechargeable aqueous zinc sodium dual-ions batteries are considered as alternatives of lithium ion batteries because of their safety and low-cost. As an available cathode for the zinc sodium dual-ions batteries, sodium manganese oxide (NMO) shows relatively high specific discharge capacity. Polyaniline (PANI) is promising for coating NMO to stabilize the NMO system because it can […]

Geocells are a type of three-dimensional honeycomb geosynthetics that are widely used to improve the performance of paved and unpaved roads by reinforcing the base/subbase courses. It is approved to benefit the long-term performance of roadways and reduction of construction cost. Although geocell has been widely used in roadway construction in cold regions, showing measurable […]

An oil well drillstring is a slender slru(.;ture whidl vibrales in 3 major coupleu moues. Unwnlrolkd vibration of the drillstring interferes with the drilling procedure. Tool and bit failure, improper borehole quality and lower penetration rates are examples of the side effects of unwanted vibration of the drillstring. Prior research by others has attempted to […]

Municipal wastewater contains excessive nutrients, which when discharged without sufficient treatment can cause eutrophication in the receiving water bodies. Digested sludge liquor, the produce water generated from the treatment of sludge that is produced from municipal wastewater treatment plant contains high concentrations of ammonia that is toxic to aquatic biota and requires further treatment. Newer […]

Sewage sludge wastes have been treated by diverse techniques to obtain sludge-based activated carbon (SBAC). These materials show excellent properties as sorbents of, e.g., organic pollutants, heavy metals, and nitrogen/phosphorous-based nutrients. In a previous research, the loading of emerging contaminants on SBAC has been achieved. As an extension of this work, we propose to study […]

Micro-Electro-Mechanical Systems (MEMS) are complex systems with sizes in the range of few microns (human hair has thickness of 150-200 microns) which have both mechanical and electronic components. MEMS technology has entered in many industries such as optical technology, point of care diagnostics, telecommunications, automotive, and military. Today, there are hundreds of MEMS devices, e.g. […]

Municipalities in Quebec lack tools to effectively anticipate and manage the consequences of beaver dam outburst flooding. When beaver dams fail the resulting flooding can pose a major threat to public safety and public and private infrastructure. A research project lead by Dr. Jan Franssen in partership with OBV RPNS and its Municipal partners is […]

In this unique research project, the researchers will document and analyze the collaborative processes and technologies in a housing project, which follows a formal Integrated Project Delivery (IPD) approach. IPD is an emerging procurement method in the construction industry that engages all major stakeholders from the beginning of the construction project. However, there is still […]

Brushless permanent magnet synchronous motors (PMSMs) are widely used in many applications including automations, instrumentation, propulsion, vehicular systems, etc. This project is focused on research and development of a modified drive system and novel control algorithms for PMSMs that could improve efficiency and torque performance compared to conventional methods. Collaboration with the University of British […]

CANDU reactors use a large number of self-powered, in-core flux detectors (ICFDs) for their reactor regulating system (RRS) and their two shutdown systems (SDS-1 and SDS-2). Dynamic characteristics of ICFDs and lead cables are very important to reactor control and safety. Although, to date, several studies have modeled dynamic characteristics of ICFDs and lead cables, […]

The availability of big data in smart infrastructures have become a strategical asset for operators to understand the situation of the infrastructure and monitor potential threats. However, most of the data still have not circulated beyond traditional corporation and technological boundaries, which have limited the visibility that could have been provided by the abundant data. […]
