Dans les centrales hydroélectriques, les groupes turbine-alternateurs sont réparés et installés selon un calendrier de travaux. Compte tenu de leur taille, d’autres pièces doivent être déplacées pour accéder aux pièces à démonter, réparer ou à installer. Afin de déterminer le plan d’aménagement des pièces, plusieurs contraintes doivent être respectées : 1) le calendrier des travaux, […]

Durham Region is committed to responding to the climate emergency by embedding climate change considerations across all elements of Regional business. This research will involve an examination of the Region’s entire waste management system and develop a full life cycle analysis model for GHG emissions which can be used to identify opportunities and support strategies […]

The aim is to improve a software tool for reliability-based quantitative analysis of dents (QuAD) in pipelines developed by Enbridge. QuAD is a tool used to predict the failure for dented pipelines, so that the deteriorated pipeline segments can be reliably identified for excavation to avoid failure. The critical concern with the current QuAD tool […]

Electric power is almost entirely transmitted through polymer insulated cables or wires in every home, factory, plant, or apparatus. If the temperature of a cable increases, it would be an indication that some accidents or malfunctions such as inflow of excess electric current occur in the cable. The generated heat, indeed, degrades the polymer insulations […]

The need for food (26.6% increase since the year 2000 according to Statistics Canada 2016) and the cost of energy are increasing rapidly as the world population continues to grow exponentially. Moreover, world-wide demand for fresh water is rapidly increasing while supply is very limited. Agriculture uses 70% of the global fresh water supply as […]

One of the main safety concerns for dam structure is damage from the scour and erosion of rock mass downstream of spillways. Therefore, the design of dam spillways to discharge a wide-ranging quantity of water with minimum rock mass scour, is one of the most important issues in designing hydraulic structures that consider the energy […]

Increasing visibility into asset inventory and gaining situational awareness in industrial control system (ICS) environment are of critical importance for electric utilities to effectively manage cybersecurity risks. In this project, we aim to investigate the solution design for electric utilities to automate asset management in an ICS, addressing the unique challenges such as device heterogeneity […]

Geophysical techniques are being increasingly used to monitor the structural conditions of dams, due to their widespread coverage and ability to detect subsurface issues, such as the development of seepage pathways. One such technique is Electrical Resistivity Tomography (ERT), which is sensitive to moisture content and porosity, meaning it can be useful for detecting areas […]

Globally buildings are one of the sectors that consume the most energy. Thus, strategies and technologies are currently being developed to improve the energy efficiency of this sector and to work towards a low carbon economy. Latent heat thermal energy storage systems (LHTES) are a viable solution to improve the overall performance of renewable heating […]

The objective of this study is to develop a district energy evaluation and plan for the Regional Municipality of Durham. This will be achieved by analyzing and assessing the current energy demand and response at the Region of Durham throughout all sectors, including commercial, institutional, industrial and residential sectors. There are numerous potential district energy […]

Our experiments will investigate the shedding of condensates when exposed to airflow (aerodynamic forces) in the microgravity environment. Shedding of droplets from a surface is a critical part of the dropwise condensation process to improve heat transfer. Because the use of gravity as a droplet removal technique is not available in space, the use of […]

Explosive eruptions on the sun’s surface eject charged particles that may travel the earth path. They cause disturbances in earth’s magnetic field and as a result, a low frequency current is induced in electrical power system transmission lines. The induced current increases operating temperature of power transformers. This overheating reduces lifetime of the transformer and […]
