Performance Characteristics Design Of Pulsed Plasma Thrusters For Drag Counter-Reacting, Dr. Sam Dakka Jan 2020

Performance Characteristics Design Of Pulsed Plasma Thrusters For Drag Counter-Reacting, Dr. Sam Dakka

International Journal of Aviation, Aeronautics, and Aerospace

Determining the performance characteristics of off the shelf pulsed plasma thrusters to enhance the life time of low earth orbiting platforms was investigated theoretically. Pulsed plasma thruster analysis was accomplished through development of correlations from historical data that distinguished between breech fed propellant to side fed propellant designs. Based on semi-empirical equations the power required by the thruster to counter react the drag was estimated and mapped for 1U to 27U CubeSat configurations for altitude ranging between 200km to 600km. It appears that the power required is dependent on the feeding delivery system design. For side fed designs the power …

Eco-Engineering Of Coastal Infrastructure: A Design For Life, Kathryn O'Shaughnessy Jan 2020

Eco-Engineering Of Coastal Infrastructure: A Design For Life, Kathryn O'Shaughnessy

School of Geography, Earth and Environmental Sciences Theses

Coastal urbanisation has driven humans to build artificial defences to protect infrastructure from rising sea level, erosion and stormier seas. Artificial structures are proliferating in the coastal and marine environments (“ocean sprawl”), resulting in a loss of natural habitat, species diversity and ecosystem services. To mitigate the impacts of ocean sprawl, the practice of eco-engineering of coastal infrastructure has been developed. A strong evidence base in support of eco-engineering is growing, yet there remain critical knowledge gaps. This work investigated the ecology of artificial structures and their ability to be enhanced in order to increase species diversity, addressing five knowledge …

Understanding The Fate Of Active Pharmaceutical Compounds In Waters Receiving Poorly Or Untreated Wastewater For The Development Of A Dedicated Environmental Risk Assessment Approach, Simone Bagnis

School of Geography, Earth and Environmental Sciences Theses

The global increasing consumption and production of active pharmaceutical ingredients (APIs) is of a growing environmental concern. The inherently biological activity of APIs creates a concern of potential ecotoxicological effects even at very low concentrations. Such risk is particularly exacerbated in low and low-middle income countries (LLMICs) where it is common the practice of direct discharge of untreated wastewater (DDUW) into surface waters, which creates a heavily polluted area downstream, described as the “impact zone”. Little is known about the environmental fate of APIs in this area. Nevertheless, measured environmental concentrations (MECs) of LLMICs show higher concentrations than for high-income …

Controls On Stratigraphy And Architecture Of Shallow-Water Deltas: Examples From The Early Cretaceous Of Central-Eastern Spain, Grant Cole Jan 2020

Controls On Stratigraphy And Architecture Of Shallow-Water Deltas: Examples From The Early Cretaceous Of Central-Eastern Spain, Grant Cole

School of Geography, Earth and Environmental Sciences Theses

Deltas form where a river meets a standing body of water (e.g. ocean) and deposits its sediment load. They are sensitive recorders of the interplay of fluvial (river) processes, that deliver the sediment to the standing body of water, and wave and tidal processes that redistribute the delivered sediment. When basinal (waves / tides) processes cannot sufficiently redistribute the delivered sediments, river-dominated deltas prevail, which are fantastic recorders of autogenic (internal to the delta) processes that control its overall evolution and internal architecture. Allogenic (external to delta) processes, such as tectonics, can influence and modify the river produced architecture. Therefore, …
