Attention problems are common with aging and related disorders (like stroke) and are associated with poor recovery and quality of life. Many clinical tests of attention are not based on neurocognitive concepts and are limited to in person visits. The Dalhousie Computerized Attention Battery (DalCAB) is a theory-based, in-depth measure of attention that can be done in person or online. It has been used in-person with young adults, but it still requires more development as a remote test.
In disaster scenarios involving airborne contaminants, where the dispersal of toxic agents can impact human lives, first responders require fast and accurate dispersal trajectory information. Existing methods that detect the local presence of an agent do not provide insight towards dispersal trajectory, and long range spread is either simulated with sparse reference data or measured long after the dispersion is complete. The lightweight and porous form of the milkweed seed offers natural inspiration for a novel sensor platform.
Oil production constitutes a significant portion of the world’s demand for sources of energy and raw materials for production of numerous daily-needed items. However, most of the currently producing oilfields are in their production decline phases with much of their oil left unproduced due to technical barriers. Sustained production of these underground resources depends on methods such as Enhanced Oil Recovery (EOR), which involves injection of specific material or energy in oil reservoirs to enhance oil displacement towards producing wells.
Thermo-photovoltaic (TPV) systems are optical heat engines that convert radiant heat to electricity using a photovoltaic cell. TPV is a highly promising technology that can potentially be used to generate electric power from any high-temperature heat source including concentrated solar radiation, industrial waste heat, heat from radioisotope decay, and fuel combustion systems. However, the performance of TPV systems needs to be improved to achieve widespread commercialization.
The world’s electricity grids need affordable batteries to store large amounts of energy and allow for increased renewable power sources like wind and solar. Instead of building new batteries from scratch, millions of used batteries from retired electric vehicles can be given a second life on the electricity grids for a lower price and a smaller environmental footprint. This research project will develop a new computer program that can manage large groups of second-life batteries so they work effectively together as a team and even outperform more expensive batteries.
In the end of this project, the proposed design will be published in two peer-reviewed journals. Also, the measure the data will be saved and analyzed in the UW-STREAM lab. After the analysis, the data converter speed, the channel selection capability and also the power consumption will be summarized and reported. From those data, both the partner and we can make a commercialized strategy. The desired applications and also the way to integrate the proposed design with the current product can be decided.
This research seeks to find a method of predicting how much heating is required to maintain comfort in homes. By collecting information such as outside weather conditions and inside temperatures along with thermostat ontime, a method of predicting the needed heat for the home will be determined. Research involves installing devices in homes that record this information which will then reported to the researcher to create a mathematical representation of how unique home heating systems respond to outside conditions.
The overall project goal is the adoption of ensiling and aerobic bioreactor system used within recirculating aquaculture systems, a developing industry within aquaculture. RAS, produce waste streams incorporating various fish wastes. Some RAS operations integrate fish processing facilities onsite, further increasing waste products. Currently waste products form these systems are disposed of through outside contractors at cost. Through ensiling and aerobic processing, the overall aim is to bring control of waste processing in-house and create additional revenue stream from the waste.
The excessive burning of fossil fuels into our atmosphere is causing our climate to change rapidly. This change in climate will have detrimental effects on home security, crop yield, energy security, and water scarcity. Many geopolitical and social pressures are present to reduce greenhouse gas (GHG) emissions. As of now over 70% of electricity in Nova Scotia is being generated by fossil fuels, more specifically over 50% of all electricity in Nova Scotia is coming from coal fire power-plants, one of the heaviest GHG emitting sources of energy.
The global population is projected to rise from about 7.2 billion in 2014 to 9.6 billion people in 2050 as predicted by the World Resources Institute. With a rapid growth of world’s population, there is a dire need for food. To cope with this ever-increasing demand for food, the use of large amounts of fertilizers, chemical pesticides and antimicrobial agents are being adopted. Although the use of agrochemicals increased plant productivity, they come at the cost of damage to the environment, agro-ecosystems and living organisms facing harmful residual effects.
