Portable electronic applications are typically powered by batteries, which have limited lifespan and size constraints. Energy harvesting from the spatial environment is a promising solution to sustainable power supplies for low-power portable devices and sensor networks. Vibration-based energy harvesting has received much attention due to the recent advances in microfabrication of piezoceramic materials. These smart materials can convert mechanical parasitic vibrations to electric charge through the direct piezoelectric effect.
Oily wastewater production and discharge from different sources such as industries and daily human activities are the main sources of marine oil pollution. More importantly, accidental oil spills occurred in oil extraction/production, refining, and transportation stages can cause detrimental impacts on the aquatic ecosystems and marine environments.
The global market of marine collagen-added products is tremendously growing, leading to the need for a stable and enormous supply of marine collagen. Atlantic salmon scales and skin are abundant in collagen, however no research has been performed for its extraction. The proposed project will develop an efficient extraction process to maximize the collagen yield, and purify the extracted collagen for its use as the functional ingredient in nutritional supplements and cosmetic products.
Canada is known globally for its prosperous fishery industry. Meanwhile, omega-3 lipids are extensively manufactured and commercialized as value-added by-products of fishery processing wastes in Canada. However, the marine omega-3 lipids are highly unsaturated and oxidizable. The oxidization of omega-3 lipids leads to significant quality loss of products. The addition of lipidic antioxidants prevent lipid from oxidation and therefore becomes one of the main-stream strategies in preserving omega-3 oil.
This project will contribute to an assessment of the historical and contemporary “state of the environment” of Bonne Bay. The aim is to establish the extent to which its marine and littoral ecosystems are resilient and “healthy”, and what changes, if any, have occurred in recent decades to its physical, biological and ecological components. These would include pelagic and demersal fish, marine plants, tides, water temperature and chemistry. Particular attention will be paid to the diversity and habitats of fish and other marine organisms, as well as to estuaries, shorelines and deltas.
Over the past few years, Graph Convolutional Networks (GCNs) have achieved state-of-the-art performance in machine learning tasks on graph data and have been widely applied to many real-world applications across different fields, such as traffic prediction, user behavior analysis, and fraud detection. However, networks in the real world are often with heterogeneous degree distributions, such as power-law.
Flying air vehicles, most commonly referred to as “drones” come in many different forms. The type of drone required to accomplish a task is dependent on the mission profile. Overcoming the barriers towards fully autonomous operations requires addressing the concerns and complying with the requirements of regulators. The objective of the research is to identify barriers and facilitators private aerospace companies have in flying fully autonomous drones in Canadian airspace.
This investigation will examine real-world potential Canadian hidden champions through a survey to gain further insight into what characteristics enable hidden champions to thrive. This survey will also expose a need for a more thorough case study (titled “A case study on Hidden Champions in North America, Europe and Asia) to examine the nuances of regional hidden champions and how they express themselves differently around the world.
Competency-based medical education (CBME) is an approach to training that combines educational objectives and time-based learning. CBME is currently being rolled out in residency training programs across Canada and represents the biggest change in medical education since the early 1900s. This project aims to determine perspectives of current residents in CBME- and non-CBME-based residency training programs at Memorial University of Newfoundland.
