    Tice, Ryan C;

    There is a growing awareness of the valuable nutrients (nitrogen and phosphorus) being lost in conventional wastewater treatment systems. Although the removal of these nutrients has been well addressed, efforts for nutrient recovery have seen little development. As the ...

    Zhao, Xinxin Cindy;

    As a promising new technology, organic photovoltaics (OPVs) have been widely studied recently. To improve the device efficiency for commercial use of 10%, a number of attempts have been made in my research. The ultra-low frequency AC field was first employed, to align p...

  • This research explores the potential of retrofitting enhanced or extended-depressed tree pits (ETPs/EDTPs) around existing street trees to bolster pre-development hydrological processes in two Hamiltonian neighbourhoods to help satisfy their social, economic, and enviro...

  • publication . Thesis . 2011
    Open Access
    Authors:
    Roberts, Timothy A.;

    We examine energy harvesting sensor networks, more specifically, a sensor network using the Geographic Routing with Environmental Energy Supply (GREES) algorithm. We start with a discussion of other sources of energy conservation both in energy harvesting and non-energ...

    Authors:
    Vadala, Brynn;

    There has been an increased necessity to search for alternative transportation methods, mainly driven by limited fuel availability and the negative impacts of climate change and exhaust emissions. These factors have lead to increased regulations and a societal shift tow...

    The radiation balance of a dwarf apple orchard was evaluated. Results compared favourably with those for a single apple tree in an earlier investigation. Reflection, heating and longwave exchange coefficients were analysed. Transmitted global radiation was measured w...

    This thesis will discuss a novel method of tracking the Sun. An essential aspect of the method is to rotate a polar aligned single axis tracker such that the angle between the direction of the Sun and the normal of the module remains at a constant angle of 23.44 degrees...

    Authors:
    Zehairi, Mazen;

    Recent discussions on global climate change have brought to our attention the largely disruptive influence of human activity on the planet and its inhabitants. Moral philosophers have added to the discourse their concerns about the unprecedented environmental problem of...
