In order to understand the movement of water in all its three phases on, under, and above the ground, scientists known as hydrologists use computer models. These models simulate the volume of water that runs through river in response to the amount of rainfall that has reached the ground during a specific time period. Hydrologists typically use weather stations to learn how much rain has fallen over the land. In Canada and in remote parts of the country, there are not many weather stations available.
Two High Voltage DC (HVDC) transmission technologies, the mature Line Commutated Converter (LCC) and newer Voltage Source Converter (VSC) technologies have their own pros and cons. For a HVDC transmission system carrying power from a single generation center to multiple load centers, by using a multi-terminal LCC-VSC type hybrid HVDC configuration, advantages of both technologies can be exploited. There is also the possibility of tapping into existing point-to-point LCC transmission lines using this hybrid configuration to supply intermediate locations.
Emulsifiers, specifically diacylglycerides and monoacylglycerides, have the potential to replace fats and oils high in saturated fats such as palm and thus provide healthy and low-caloric food products. Canola based DAGs and MAGs not only can reduce the saturated fat content and food calories, they also can improve the functionalities of food products. However, they are produced using costly and environmentally unfriendly enzyme in solvent systems, and have shortcomings when utilized in certain food applications.
As the consumption of cigarettes declines in North America and Europe market, a company that specializes in manufacturing specialty papers is seeking new opportunities with its natural fiber productions. This research intends to identify new market trends and opportunities for natural fibers in the competitive environment; provide a comprehensive analysis in worldwide natural fiber industries; and to develop strategies by applying marketing segmentation strategy and differentiation strategy to respond to the market.
With increased emphasis on water quality in the Lake Winnipeg watershed, more stringent guidelines for wastewater effluents are being implemented. Smaller municipalities and remote communities, with limited financial resources, will be facing regulatory pressures, particularly around discharge of phosphorus, as well as micropollutants such as estrogens, pharmaceuticals and pesticides. To ensure the release of high quality wastewater effluents post-lagoon treatment technologies such as subsurface filtration systems are being employed for enhanced removal of pollutants.
This research will investigate Wide Area Measurement based controllers for improving stability in systems with HVDC and FACTS devices embedded in AC networks. The approach will extend the candidates Ph.D. research which introduced a new method that is always able to guarantee improved damping of all modes in the face wide changes in the network. The approach will lead to controller designs which are robust against configuration or operating point changes, or communication loss.
Seizures are rare while dreaming in rapid eye movement (REM) sleep. New research, however, suggests seizures may rebound during unstable REM sleep. This may be due to brain wiring (connectivity) since a highly connected brain is more prone to seizures, and connectivity changes from wakefulness to sleep. Brainwave tracings (EEG) can generate connectivity maps (connectomes) but adequate connectome resolution requires many EEG electrodes (high density EEG). This study uses high density EEG to examine brain connectomes and seizure susceptibility in unstable REM sleep.
Riverview Health Centre (RHC) plans to renovate their special care units and grounds, which accommodate 60 residents with intermediate and advanced stages of dementia. The main purpose of this study is to examine the effects of the renovations on residents, family and staff using a multi-methods research approach and a multi-disciplinary team of researchers (i.e., architecture, sociology, kinesiology, clinical psychology, pharmacy, nutrition, nursing, and health sciences).
Glioblastoma multiforme (GBM), also known as glioblastoma and grade IV astrocytoma, is the most common and most aggressive cancer that begins within the brain. There is no clear way to prevent the disease. Typically treatment involves surgery after which chemotherapy and radiation therapy is used. The medication Temozolomide (TMZ) is frequently used as part of chemotherapy. Cholesterol lowering drugs (statins) is recently being considered as a novel and safe approach for combination therapies in many cancers.
The proposed study will develop seismic design guidelines for retrofitting deficient concrete bridge columns with sprayed fiber reinforced plastic (FRP). Seismically deficient bridge columns (with different aspect ratios and transverse reinforcement ratios) retrofitted with composites will be tested under reverse cyclic loading. The tests will determine various damage states in terms of strain and drift.
