Porous materials as a filtration method for ship exhaust

The Canadian government has vowed to reduce their pollutant emissions by 2030 in order to curb the effects of climate change. This means that shipping companies must make strides to reduce their overall emissions. This project will use novel sponge-like frameworks, called metal-organic frameworks (MOFs), to remove environmentally toxic pollutants from exhaust gas. The materials currently being utilized for pollutant gas removal (e.g.. limestone) are often are very minimally active by weight, this is not the case for MOFs. MOFs possess a large internal surface area making them very active by weight, and ideal for filtration. These frameworks are able to be tailored to target the removal of specific pollutants and do so at a high capacity. If deployed in filters/pellets for marine vessels, MOFs could greatly reduce the waste associated with the current scrubbers while increasing the capacity for pollutant removal and ultimately slowing the onset of climate change.

Automated diagnosis of liver fibrosis and steatosis using deep-learning algorithms applied to conventional liver ultrasound

Non-alcoholic fatty liver disease (NAFLD) is one of the most common liver disorders worldwide. NAFLD could lead to end-stage liver disease and considered as one of the most common causes of liver transplantation. Moreover, a large number of liver transplant recipients develop NAFLD after transplantation due to side effects of the medications that they have to use to keep their new liver healthy. Although liver biopsy has been used for a long time to evaluate the liver condition it is associated with a risk of bleeding and other side effects. Consequently, we aim to improve simple liver ultrasound method by adding some artificial intelligence algorithms to the images obtained from this method to diagnose NAFLD and other liver disorders after transplantation. By doing so, clinicians will be able to perform real-time liver ultrasound without the need to refer the patients to a radiologist for the procedure.

Green & Culturally Appropriate BuildingDesign

The project aims to develop a process to design houses using locally sourced materials and labor.
This process can be transferrable to other communities in the future when they approach a new
housing project in their region. This would be culturally and aesthetically in line with the vernacular.
The design will incorporate passive systems that make use of the naturally occurring forces of nature
(i.e., wind, sun, etc.) to provide better living conditions. People residing in the communities have been
consulted with in the past by Ecotrust Canada to gather information that will be critical in designing the
aesthetics as well as the functional components of the buildings. This project would provide
community members with employment opportunities, during the construction stage, and in the future
maintenance of the homes. There will be an economic analysis pertaining to monthly spending on
water, utilities and electricity bills to get a better understanding of the feasibility of adopting energy
and water savinG…tobecont’d…

Scheduling of agents from forecasted future callarrivals at Hydro-Quebec’s call centers

The call center managers at Hydro-Quebec (HQ) need to deliver both low operating costs and high
service quality. Their task is made especially difficult because they need to handle a large-size
workforce (more than 1000 employees) while meeting an incoming demand which is typically both
time-varying and uncertain. The current techniques of determining the schedules of each employee
according to the forecasted future call volumes at HQ are often unreliable, and there is a need for new
and more accurate methods.
In this project, we propose addressing the concerns of the call center managers at HQ by developing
new methods for multi-activity shift scheduling that consider the very specific union regulations of HQ
(variable schedules) and are validated by mathematically simulating the main event that rule the callcenter
(arrival calls, processing time, abandonment, etc.). Our method will exploit the strong
properties of language-based model to efficiently consider complex regulations, as well as the
accuracy of mathematical simulation to reproduce in…TOBECONT’D…

CONCEPTION ET FABRICATION D’UN BANC D’ESSAI POUR UN RÉCOLTEUR D’ÉNERGIE PROVENANT DU ROTOR D’UN HÉLICOPTÈRE

La récolte d’énergie (“energy harvesting” ou “energy scavenging”) a connu une croissance importante au cours des dernières années. C’est le processus de récupération de l’énergie (voir Figure 1) des sources externes (solaire, thermique, éolienne, acoustique, mécanique/cinétique, etc.) et de conversion en électricité utile à petite échelle. Dans l’industrie aéronautique en particulier, la conversion d’énergie vibratoire en énergie immédiatement utilisable ou stockable pour alimenter des capteurs, des microprocesseurs ou encore des micro-systèmes électromécaniques (MEMS) peut être une voie intéressante vers l’optimisation énergétique. La récupération d’énergie vibratoire serait encore plus profitable notamment pour les engins volants du futur qui seront, pour la plupart, propulsés par des moteurs électriques. L’objectif de ce projet de recherche est donc de concevoir et de fabriquer un banc d’essai de récolte d’énergie vibratoire résiduelle provenant du système de transmission principal d’un hélicoptère. Une approche globale combinant des analyses numériques et des essais expérimentaux sera utilisée pour évaluer la faisabilité, l’applicabilité et la robustesse des solutions proposées. Ce projet de recherche sera réalisé au Laboratoire d’Analyse Vibratoire et Acoustique (LAVA) du département de génie mécanique de l’École Polytechnique de Montréal, en collaboration avec Bell Textron Canada Ltd.

Improving Health Information System Safety: Development of Novel Approaches for Identifying, Tracking and Preventing Technology-Induced Error

In Canada healthcare is being modernized and transformed through a range of new healthcare
information technologies and systems. Applications of information systems such as electronic health
records (EHRs), electronic medical decision support and an increasing range of mobile health
applications promise to transform and improve healthcare and increase patient safety. However,
although such technology has huge potential benefits, research has shown that if not designed, tested
and implemented properly such technology also has the potential to introduce new types of error – i.e.
technology-induced error that arises during the complex interaction of health information systems with
healthcare workers under the varied complex situations and environments in which healthcare IT is
deployed. In this proposal AE Informatics will be able to extend its pioneering research in this area in
developing new and novel methods for detecting, classifying and mitigating technology-induced error in
healthcare IT. The cluster of projects include work in improving the safety of key healthcare processes
for ensuring medication safety…TOBECONT’D…

Inputs and outputs of inhibitory reticulospinal cells in lampreys

Locomotion is a basic act that humans and animals use in everyday life to move in the environment. There has been an ongoing effort for at least a century to understand the mechanisms that the brain uses to control locomotion, including starting and stopping. Studying those mechanisms at the level of single neurons, and finding how their participate in locomotion is a difficult task, especially in humans and mammals, mostly because of the large number of neurons involved and the very complex networks that they form. This is why researchers have always looked for simpler animal models that can still provide insights as to how locomotion works in humans. One such model is an aquatic vertebrate that swims with simple ondulatory movements, the lamprey. This peculiar fish has a very simple brain with neurons and general structures that are very similar to what is found in humans. Previous studies on lampreys have shown that some cells that participate in controlling locomotion are inhibitory in nature but their role hasn’t yet been defined. A possible role of these cells would be to send an inhibitory signal to the spinal cord that would help stop ongoing locomotion.

Vers l’élaboration d’une plateforme collaborative de création et de partage de connaissances dans un contexte de crise sanitaire (ex. pandémie) et environnementale (ex. catastrophes naturelles) en services préhospitaliers et hospitaliers.

Notre intention est de réaliser les travaux préalables à l’élaboration d’une plateforme collaborative de création de partage et la mise en application des nouvelles connaissances générées dans un contexte de crise sanitaire et/ou environnementale mettant l’accent sur les services préhospitaliers. Ces travaux sont à la fois théoriques en répertoriant les connaissances actuelles sur l’utilisation des applications d’écriture collaborative dans un contexte de crise. Ils sont également empiriques en analysant les stratégies actuelles de transmission des connaissances cliniques et administratives dans un tel contexte et en établissant les besoins et les attentes permettant la co-construction de ladite plateforme. Le projet apportera des avantages économiques significatifs pour Dessercom en termes de productivité et de performance en participant à la conception des directives beaucoup mieux adaptées à la réalité terrain à l’intérieur de laquelle les paramédics se doivent intervenir et en évitant les transferts inutiles des usagers d’un territoire à l’autre.

Maternal Augmentation and Digital Empowerment Initiative in Tanzania (MADE-IT)

Shortages of skilled healthcare professionals and unequal distribution of healthcare professionals throughout the country are two key challenges causing unexpectedly high number of preventable maternal deaths in Tanzania. Hence, developing innovative solutions that take fewer resources but have a wider impact on Tanzanian midwifery education system is crucial to avert these deaths. Canadian Network for International Surgery (CNIS), with 25 years of midwifery teaching skills in Africa has developed a project called “Maternal Augmentation Digital Empowerment Initiative in Tanzania”- the main goal of the project is to examine the effectiveness of digital midwifery education compared to the traditional classroom based education in developing skilled nurses and midwives. If equally effective, the digital approach would be superior in that it is substantially less resource-demanding to teach a greater number of students; in addition, if demonstrated successful in Tanzania, this approach can be widely scaled in other countries with a similar context.
