Transport energy demand: techno-economic modelling and scenarios for Irish climate policy
The case for energy policy modelling is strong in Ireland, where stringent EU climate targets are projected to be overshot by 2015. Policy targets aiming to deliver greenhouse gas and renewable energy targets have been made, but it is unclear what savings are to be achieved and from which sectors. …

Does energy follow urban form? : an examination of neighborhoods and transport energy use in Jinan, China
… of neighborhood form and location on household transportation energy use in the context of Jinan, China. From a theoretical perspective, energy use is a derived outcome of activities, and households choose their travel patterns to maximize net utilities subject to constraints of time, budget and …

Analysis of laminated sediments from Lake DV09, northern Devon Island, Nunavut, Canada
… during this period suggesting increased sediment transport energy. The coldest period of the Little Ice Age appears to be during the AD 1600s. Varve widths over the past century indicate climate warming in the region.

Modeling personal vehicle energy consumption to assess the potential for electrification and decarbonization
This thesis develops a new model of the energy requirements of personal vehicle travel and uses it to evaluate tools to decarbonize the transport sector. Energy use and carbon emissions from transportation are spread across millions of miles of roadways and hundreds of millions of travelers. This …

Energy loss and equilibration of a highly energetic parton in QCD plasmas
… or quark) traverses the medium, it loses its energy as a result of interactions with the medium. In this thesis, we describe the full in-medium kinetic and chemical equilibration of hard particles, using a linearized effective kinetic description of QCD at leading order. Since we include …

Sedimentary Characteristics of an Estuarine Marsh System and the Roles of Storm Overwash, Micro-tidal Currents, and Organic Production: Big Branch Marsh, Louisiana
… influences of fluvial, tidal, and storm overwash transport dynamics of a micro-tidal estuarine marsh system. Collected sediment samples from tidal channel beds, pond bottoms, and marsh surfaces were analyzed for organic content and particle-size distribution. Parameters of sub-environment groups …

Geopolymer-based moisture and chloride sensors for nuclear concrete structures
The reinforced concrete structures that support transport, energy and urban networks in developed countries are over half a century old, and are facing widespread deterioration. The main cause of degradation - reinforcement corrosion, accelerated by moisture and chloride exposure - costs the global …

Physics from Time Variability of the VHE Blazar PKS 2155-304
… the principal extragalactic sources of very high energy gamma-ray emission in the Universe. These objects constitute a sub-class of Active Galactic Nuclei whose emission is dominated by Doppler boosted non-thermal radiation from plasma outflowing at relativistic speeds from the central engine. This …

‘Money and (dis)connection’: Income inequality and network disadvantage as barriers to sustainable technology adoption
… sectors: telecommunications, waste management, transport, energy and water. Does existent income inequality translate into adoption gaps within these sectors? Is inequality an obstacle for advancing the vision of an inter-connected and more sustainable world? This research explores these …

Harnessing Vibrations for Efficient Exciton Dynamics in Semiconducting Energy Materials
… in the excited-state dynamics of semiconducting energy materials. We examine these effects in self-assembled organic semiconducting nanostructures and small molecules, focussing on the implications for exciton transport, energy transfer, and light emission. Special use of ultrafast laser …

The role of Stl1p in glycerol accumulation in osmotically stressed icewine yeast Saccharomyces cerevisiae K1 V1116
… the contribution ofStl1p in active glycerol transport (energy dependent) during Icewine fermentation, we first developed an Stllp-dependent (14C]glycerol uptake assay using a laboratory strain of S. cerevisiae (BY 4742 and LiSTLl) that was dependent on the plasma membrane proton gradient and …

Engineering the optical properties of luminescent solar concentrators at the molecular scale
… at the edge. This thesis addresses the two main energy loss mechanisms in LSCs, namely transport losses and trapping losses. We used phycobilisomes, a biological light-harvesting complex, as dyes in the LSC collector to circumvent transport losses caused by photon re-absorption. The selfassembled …

Model predictive control for energy efficient cooling and dehumidification
Energy has become a primary concern in countries worldwide, and is a focus of debates on national security, climate change, global economy, and the developing world. With more people in developing countries adopting the lifestyle of western countries as rapidly as possible, limited only by economic …

Reinventing Infrastructure Economics: Theory and Empirics
… enterprises improve infrastructure services--transport, energy, and water--particularly in developing countries. This research is relevant because, despite successful privatization of infrastructure that yielded over trillion and a half dollars in investments since 1990, infrastructure …

Towards Sustainable Freight Energy Management - Development of a Strategic Decision Support Tool
Freight transportation, in its current shape and form, is on a highly unsustainable trajectory. Global demand for freight is ever increasing, while this demand is predominantly serviced by inefficient, fossil fuel dependent transportation options. The management of energy use in freight …
