Open source Layer Batching For Waste Reduction In Multi-Material 3D Printing

The most popular type of 3D printing globally uses plastic filament. Historically, this has been done with only one plastic at a time. 3D printers can now use multiple materials and/or colors to be part of a single print. Unfortunately, today multi-material 3D printing results in a lost of waste plastic and the associated environmental problems. Each time a material change happens, waste is produced through nozzle priming and/or purging to get rid of the last material. 3D printing software typically changes the material on each layer meaning that every layer, a lot of plastic is wasted. The goal of this project is to develop solutions to radically reduce this waste and to apply it into open source software so that all multi-material 3D printers can reduce their waste. This will allow for material changes to be done less frequently than on each layer using a strategy called “layer batching.

Ground validation of aerial detection technology to determine urban forest tree health for use in municipal urban forestry programs

The use of aerial drone sensing (remote piloted aerial surveillance) technologies has greatly expanded over the last decade into the agriculture/forestry, construction, mining, engineering/surveying, and public safety sectors. One such area of growth has been in the detection and assessment of plant condition and health in the agriculture and forestry industries. The use of this technology has the potential of providing improved the efficiency and effectiveness of the management of insect and disease pests in municipal urban forestry programs. The purpose of this project is to determine the effectiveness of remote based multispectral technologies using drones to identify the presence of Dutch elm disease (DED) in elm trees in the City of Winnipeg. Speed and the ability to cover large areas through disease detection surveys afforded by remotely piloted aircraft systems surveillance would be useful in charting the spread of the disease in urban neighbourhoods, and allow implementation of control methods within shorter time frames.

Analyse structurelle et quantitative de l’ABS post-consommation et recyclé par spectroscopie infrarouge.

Ce projet de recherche est intimement lié à la diversification de la technologie de recyclage de Polystyvert, afin de s’étendre à d’autres plastiques de la famille du polystyrène, comme l’ABS. Durant ce procédé, le plastique contaminé provenant du consommateur est mis au contact d’un solvant qui a pour but de le solubiliser, puis d’un autre, appelé anti-solvant, pour le précipiter. La connaissance précise des motifs d’acrylonitrile, de butadiène et de styrène présents dans l’ABS de post-consommation, et recyclé, est essentielle pour l’élaboration d’un procédé efficace. Ce projet de recherche consiste donc en l’élaboration d’une méthode sensible et robuste de dosage par spectroscopie infrarouge. L’impact des contaminants tels que les pigments, retardateur de flammes, etc, présent dans les déchets prétrier devront être évalué, et pris en compte pour l’optimisation de la méthode.

Simulation-based study on seaport-rail intermodal transportation toward port capacity efficiency and GHG emissions reduction

Ports play a pivotal role in the operations of global supply chains but face critical challenges such as increased congestion in cargo flows and greenhouse gas emissions reduction. A promising solution avenue is a better integration of port operations with land-based transportation networks, especially rail transportation. Such endeavour requires advanced operations management of port capacity in order to increase the efficiency of intermodal operations (port-rail) and reduce its carbon footprint. This project aims to develop a simulation approach capable of evaluating the efficiency gains and greenhouse gas emission levels of various scenarios aiming improvements to the intermodal transport system and thus support port’s decision-makers.

Novel Artificial Intelligence (AI) driven wearable device for continuous vital sign monitoring

Wearable medical devices (SWDs) are emerging as powerful patient monitoring and data collections tools. These smart, multiplexed devices allow us to quantify dynamic biological signals in real time through highly sensitive and miniaturized biosensors. SWDs can enable monitoring at risk patients at home, diagnosing early disease progression, and reducing healthcare expenditures by means of prediction and prevention of disease. Company X has developed a novel Artificial Intelligence (AI) driven wearable device that detects, and monitors blood oxygen saturation, heart rate, respiratory rate, and blood pressure all at a single point of contact at the wrist called AI-Vital. The general aim of the proposed research is to perform pre-clinical safety testing for this AI-powered medical device to drive it forward towards US Food & Drug Administration (FDA) / Health Canada regulatory approval.

Preclinical assessment of the novel compound d-Govadine as a treatment for cognitive impairment in psychiatric disorders

Cognitive impairment is a debilitating feature of psychiatric disorders such as schizophrenia, substance use disorders (SUD), depression and Alzheimer’s disease. There is a significant need for treatments targeting key cognitive deficits including working memory and behavioral flexibility, and the development of these therapeutics have the potential for broad clinical use in psychiatry. d-Govadine (d-GOV) is a novel, plant-derived compound that has been shown in rodent studies to facilitate and restore these key cognitive functions that are impaired in schizophrenia and SUD. Although the mechanism of d-GOV is unclear, it appears to uniquely modulate dopamine signaling in the prefrontal cortex. The aim of this project is to investigate the mechanism of action of d-GOV and its safety, absorption and metabolism in the body, critical information for submitting an investigational new drug (IND) application to advance d-GOV to clinical trials. This preclinical assessment is made possible by partnering with Resilience Biosciences Inc, which in turn enables them to submit an IND application for d-GOV.

Use of UHPC as a building material in Northern climates

In this project different UHPC mixes will be proposed and tested for mechanical and physical material properties when subjected to extreme cold temperatures. The mixes which meet the required properties and are most economical will be used for further structural wall panel testing and will be proposed to the company. The proposed concrete mix will be used to build insulated sandwich wall panel specimens and structural strength test will be conducted on them. The results of this research will be provided to the company and help them in finding the most cost efficient, durable and lightweight sandwich wall panels solution for mass production in modular housing.
The partner organization will use the proposed UHPC mix in sandwich wall panel production which will ultimately be used in northern climates. Usually, UHPC mixes are proprietary and expensive to purchase but accessing to a UHPC mix design through research collaboration with UNB will be very economical for the company. In addition, by using UHPC instead of traditional normal weight concrete amount of material, volume and weight will be reduced resulting in less transportation cost and lifting and moving costs during assembly.
