Student work for start-up making waves in maritime innovation

Founded by a pair of Dalhousie University alumni of the materials engineering program, Nova Scotia-based Graphite Innovation and Technologies (GIT) is providing opportunities for Dalhousie graduate students to put their research experience into practice through Mitacs internships.  

Wire arc additive manufacturing and post-fabrication heat treatment of PH 13-8Mo martensitic stainless steel

The proposed Mitacs E-Accelerate project aims to develop the application of 3D-printing technique, and facilitate the transformation from conventional fabrication methods to newly developed additive manufacturing technologies for Canadian industrial sectors. One of the main barriers that prevents the wide-spread utilization of 3D-printing technique is the uncertainties in the resultant performance of the as-printed parts. Therefore, this project will focus on the better understanding of the resultant microstructural features and mechanical properties of the 3D-printed metallic components.

Utilizing Remote Sensing and Machine Learning to Improve Poultry Farm Productivity

Within the Canadian context, poultry farmers are constrained by regulations that predetermine chicken prices and market supply. As a result, they are limited in the approaches they can take to improve the profitability of their operations. Within this regulatory framework, farmers must rely on measures that can be applied on their farms to improve chicken’s growth performance while reducing production costs. In this project, we aim to find the effective approach to utilizing remote sensing and machine learning to improve poultry farm productivity.

A lab-on-chip fish welfare sensor for application in aquaculture

We propose using the Cortisol hormone, secreted from the fishes during stressful events, to provide ongoing monitoring of fish welfare while in their habitats. Instrumented aquaculture pens will allow operators to continuously be aware of threats to fish health, including harmful blooms, predators, and/or poachers. As Canadian aquaculture capital investments are remote and offshore, a low-cost and low-maintenance Cortisol sensor would be ideal for these sites.

Ground Disturbance and Downed Woody Materials following Diverse Timber-Harvest Methods in the Pockwock Watershed

The forWater Network, funded by the federal government as well as industry partners and provincial governments, is a national research network looking into the impacts of forest-management strategies on drinking-water source quality and treatability. forWater Network researchers at Dalhousie University (including Duinker, the supervisor in this application) are working with Halifax Water and Westfor Management Inc. to determine how the Pockwock forested watershed can be managed to improve water treatability. A key issue here is the movement of dissolved organic carbon (DOC).

Formulating and solving the multi-calendar resumable and non-resumable Naval Surface Ship Work Period Problem

This project deals with the development of a new mathematical model and a fast solution method to optimize the multi-calendar naval surface ship refit scheduling problem with resumable and non-resumable operations. The Naval Surface Ship Work Period Problem (NSWPP) is a highly complex resource-constrained project scheduling problem (RCPSP) with many work orders that are equivalent to small projects.

Development of alternative technologies to assess muscle functionality

Skeletal muscle is a dynamic tissue that undergoes many regeneration processes during our lifetime. Loss of skeletal muscle is known as muscle atrophy or sarcopenia and is directly related with quality of life and life expectancy. There are very few diagnostic tools to identify muscle atrophy and the ones available are time-consuming and expensive. Therefore, the most used diagnostic measure for accessing muscle atrophy and recovery is physical examination for patients with a certain mobility status.

Textile Embedded Vital Health Signs Monitor

The goal in medicine is prolong life and prevent disease before it spreads and becomes irreversible. There must be a way to easily self-monitor or to allow medical professionals to continuously remotely monitor high risk patients. The main vital signs that ideally should be constantly evaluated are pulse rate, respiration rate, body temperature, oxygen saturation levels and blood pressure. Other secondary figures that should be watched over are glucose levels, cholesterol levels among others.

Aeration design and bioreactor optimization for nutrient recycling systems

This research project will look to help Cultivated Ecosystems Ltd. redesign their current reactor that they use for generating organic nutrients and beneficial micro-organisms to enable them to produce the quantities needed on a regular basis for commercialization. It will look at how these micro-organisms grow under different conditions and create new equipment that will ensure the products formed are beneficial for plants and soils.

Experimental and Analytical Study on Sustainable Sandwich Structures made from Recycled Plastic Core and PET FRP facing

The project seeks to discover the optimum design and commercialization strategy for newly developed sandwich structures derived from recycled plastic for the civil engineering sector. The sandwich structures are highly sustainable and could potentially consume large amounts of the rapidly produced plastic waste. The final sandwich product would have the potential to be used in various applications such as roof panels and exterior/interior walls of buildings.
