Efficient design and implementation of concatenated error-correction coding for high-throughput fiber-optic links

The project targets design and implementation of error-correction codes for high-throughput fiber-optic communication links. We focus on the error-correction encoding at the transmitter side as well as decoding at the receiver side considering the simplicity of implementation and low power consumption at both transmitter and receiver.

Characterization of a novel 3D-FML for submerged turbine application

The proposed research aims at increasing the efficacy of tidal turbines by incorporating light-weight and resilient blades into a currently used turbine. For that, a recently developed 3D fiber-metal-laminate (3D-FML) material at Dalhousie University will be used. In comparison to metals that are presently used to form blades, or potentially fiber-reinforced composites, the 3D-FML would facilitate lighter weight and greater specific strength and stiffness, in a cost-effective manner.

Lessons Learned and Decision-Making Tool for Engineering Projects

According to the World Petroleum Council (WPC), the average age of employees in Oil and Gas companies is 50 years, and it is estimated that in the next 5 years 40-60% of them will retire. The consequence is an age-related crisis in the sector given that, in many cases, the knowledge accumulated goes with the retiring gray-beards.

Factors influencing overwintering survival in the tick Ixodes scapularis, including the effect of infection with Borrelia spp.

The plan is to research the physiology and behaviour of Ixodes scapularis, and Dermacentor variabilis ticks with and without the presence of Borrelia burgdorferi bacterium, Rickettsia bacterium, Francisella bacterium, and Bartonella bacterium to answer the overarching question: Are tick-borne bacteria that are pathogenic to humans also harmful to the tick vectors in Nova Scotia? Cold hardiness and fat content, and temperature preference will be used as measures of physiology and behaviour respectively.

Examining brain activity and sport-specific skill learning due to motor imagery

This research will use a brain imaging device newly developed by Axem Neurotechnology to investigate whether providing real-time information on levels of brain activity can help human participants more effectively engage in mental practice. Mental practice has become a widespread addition to the training schedules of elite athletes, as it has been well documented that upon completion of optimal levels of physical training, further performance benefits can be achieved from additional practice consisting solely of imagining performance.

Optimizing Biofiltration for Improved Manganese Control under Winter Conditions

The presence of manganese in drinking water supplies has been problematic for drinking water providers as it can be difficult to remove during treatment and it creates aesthetic challenges, such as colored (e.g. black, brown) and bad tasting/smelling water. Recently, Health Canada has proposed a health-based maximum acceptable concentration for Mn of 0.10 mg/L. Biofiltration technology is growing in popularity as a sustainable method for removing Mn from drinking water; however, there is a lack of evidence to support the effectiveness in cold water (less than 10ºC).

Development of an RNAi Approach to Control Wireworms on PEI

Wireworm (click beetle) has becoming a devastating pest for the potato industry in Prince Edward Island (PEI) and many places in the country and around the world. It is a soil born insect that can penetrate a large number of potato tubers, degrading their quality for processing. The problem is more difficult to control after the ban of soil fumigation was in place in PEI. This proposed work is aimed at developing the RNAi technology by targeting the key genes for insects’ survival and development to control the insect population.

Effects of probiotic treatment on maternal care and gut health, with outcomes for offspring stress resiliency

The care provided to children by their mothers is important for the development of a healthy stress response. Many things may affect the quality of a mother’s care, such stress, environment, and nutrition. Probiotics, a form of good bacteria found in the digestive system, have been shown to improve the wellbeing of offspring in rodents who are exposed to on-going forms of stress. We wish to investigate if probiotics improve a mother’s care towards her offspring, and the later ability of these offspring to respond to stress in a healthy way as they  develop in adolescence.

Investigating wildlife-road interactions in the Chignecto Isthmus Region

Roads threaten wildlife throughout the world when animals experience increased collisions with vehicles and decreased access to important habitat and resources. This research will investigate where animals are crossing roads in the Chignecto Isthmus of Nova Scotia, a region highly impacted by human development. The results will provide evidence for hotspots of negative wildlife-road interactions, with the goal of recommending effective changes to road infrastructure for the benefit of both animals and humans.

Potential roads for recovery of Atlantic salmon in Nova Scotian rivers

Atlantic salmon and its associated fisheries have a rich and complicated history in Nova Scotia. Commercial and recreational overfishing, as well as habitat damage and environmental pollution have all contributed to the species’ decline. For a century, work on rebuilding populations has met with varied successes. This history, and relative successes of different measures, will be reviewed and synthesized in this project, with a specific focus on potential recovery options for the Margaree in Cape Breton.
