Anaerobic digestion is an environmentally-friendly process that breaks down biomass into simpler, more stable components, while simultaneously capturing energy in the form of a methane-rich biogas. Digesters are usually used to treat wastes, such as at municipal waste facilities, or from livestock farms. However, anaerobic digesters are not very reliable, suffering from occasional “digester upsets”. Consequently, anaerobic digestion is less attractive to industry as compared to other less environmental alternatives. The reason behind this unreliability lies in the complexities of anaero
The key challenge of condition monitoring is to predict, based on non-destructive inspection and operating data, whether or not a piece of equipment needs replacing or not. In this case the piece of equipment is an overhead power conductor – a critical element in electrical power supply. Measuring the voltage level of an overhead conductor presents a challenging engineering problem.
Being able to accurately determine the model parameters for multi-conductor overhead and underground cable systems is important for power transmission system simulation. Current analytical based methods are limited to simple configurations of conductors and employ approximations that limit their accuracy at high frequencies. In this project we develop a numerical Finite Integration based technique for calculation of transmission line parameters and for calculation of the associated electromagnetic fields.
The wear of polyethylene components in total knee replacements is one of the major factors limiting the longevity and success of knee replacements. The project will use finite element analysis and mathematical wear calculations to model wear in a total knee replacement. The model will then be used to compare the wear rate of conventional polyethylene, normally used in knee replacements to the new highly]cross linked polyethylene which recently became available.
This internship will numerically simulate the impact of flow structures on power production from river kinetic turbines. These turbines extract renewable energy from rivers from flow velocity rather than from a drop in river levels. To date, a proper mathematical approach of how to place these turbines in a river is not available. Mathematic tools are required to estimate the power reduction when these turbines are subjected to large flow variations in river applications created by river bank profile changes, turbines located upstream, and due to localized changes in the river levels.
We aim to use 3D stereo display to visualize a data bank of characteristics common to spiral galaxies. We plan to use an immersive environment at the Industrial Technology Centre's Virtual Reality Centre (VRC), i.e. a "half]cave" in which the user walks around and interacts with the data. Our approach will use advanced computer algorithms, supplied by nQube, working in combination with the human vision system to select colours which will be optimized for emphasizing relationships between galaxy characteristics.
The demands of precision agriculture have caused significant changes to agricultural machines. Improved sensor technology makes it possible to monitor numerous parameters. Access to GPS signals has made it possible to monitor the variation in yield within a field. Perhaps the most significant change is that access to the GPS signal has made it possible to develop guidance systems that provide accurate guidance information to the operator or even guide the agricultural machine for the operator.
The Greater Winnipeg Area (GWA) white-tailed deer (WTD) population has grown substantially over the last three decades. Growing urban WTD populations in heavily human populated areas have led to human-deer conflict and represent a significant human health and safety concern. A major human safety concern is the alarming increase in the number of motor vehicle accidents within the city involving WTD. In addition, WTD host a number of diseases transmittable to humans and other wildlife, and deer cause significant property damage.
