Landfilling of waste is an operation that has huge impact on both water and air quality. Modern landfills can be designed to minimize impact on groundwater resources and reduce Municipal Solid Waste (MSW) in old landfills, which typically undergo a slow, anaerobic biodegradation process that produces methane gas. It is estimated that global methane emissions […]

Automated object detection and tracking in videos is still one of the challenging problems in computer vision. Generally, it is a very challenging problem due to the loss of information caused by the projection of the 3D world on a 2D image, noise in images, cluttered background, complex object motion, partial or full occlusions, changes […]

Canada owns the largest heavy oil and bitumen reserves in the world. Unfortunately, extracting these hydrocarbons is difficult due to their high viscosity. Currently, the most popular strategy is to heat the bitumen using steam, but steam injection can be inefficient and is not suitable for all reservoirs. Radio frequency heating offers a flexible and […]

The direct borohydride fuel cells (DBFCs) are a much simpler system compared to the hydrogen fuel cell, in terms of fuel infrastructure. The mystery behind the borohydride oxidation reaction mechanism hinders its commercial utilization. To effectively tackle the challenges with DBFCs, it is crucial to identify a highly active catalyst and understand the nature of […]

Black carbon (BC), generated from incomplete combustion of carbonaceous fuels, is one of the two major airborne pollutants that drive climate change and degrade regional air quality. With a warming potential second to CO2, BC contributes the most uncertainty to climate modeling due to its short retention time in the atmosphere and poorly understood mixing, […]

In North America, more than 75 percent of the population is served by wastewater collection systems and treatment plants for which concrete is a key construction material. Unfortunately, thousands km of lines must be removed each year for replacement suffering from corrosion which caused by prolonged exposure of concrete surface to highly aggressive environments. Concrete […]

A sustainable system is supposed to satisfy its stakeholders’ social, financial, and environmental requirements. Although there are many studies to optimize design decisions in a sustainable system, limited research is found to consider multiple objectives in sustainable system design. We study Eco-Industrial Parks (EIPs) as a sustainable system where businesses and local communities collaborated together […]

In agricultural watersheds, many meandering rivers were straightened and several rectilinear ditches were added to the drainage network in order to evacuate water as quickly as possible in the spring to improve farm productivity. The design of these modified channels was not based on natural river dynamic concepts, which include both discharge capacity and sediment […]

Le contrôle de qualité de comprimés pharmaceutiques implique habituellement des analyses requérant une préparation laborieuse des échantillons, ce qui occasionne des coûts élevés et des délais considérables. À ce jour, peu de technologies permettent une analyse rapide et/ou en ligne d’ingrédients actifs à de très faible concentration massique (sous 1% massique). L’objectif général de ce […]

Global population growth, urbanization and changing climate patterns have increased the demand for potable water, wastewater reuse and value recovery from wastewater, and treatment of industrial process water. Population growth also results in increased demand for the shipping of goods by ocean freight, with the associated risk of the transport of unwanted marine life from […]

The production rate of petcoke is growing rapidly because of continuous increase in the volume of heavy crudes. This poses a long-term challenge to the upgrading and refining plants to find an economical petcoke utilization approach and reduce their waste products and also environmental impacts. In addition to its profitability feature, this technology should ideally […]

Because of the toxicity of selenium, its removal from waste water is a crucial treatment before discharging. Selenate (Se(VI)) and selenite (Se(IV)) are the most common species of Se in waste waters. There are many efficient methods for removal of selenite from wastewaters (e.g., ferrihydrite chemical co-precipitation, cementation, or adsorption) while the removal of selenate […]
