Local variation and regional transport of tropospheric ozone over Cape Town
… the brown haze in Cape Town. However, due to the transport of air pollutants, emissions from remote sources may also contribute to air pollution levels in Cape Town. This dissertation investigates the local variation and the regional-scale transport of atmospheric pollution over Cape Town, with a …

Regional Transport Aircraft Design using Turbo Electric Distributed Propulsion (TEDiP) System
… propulsion (TEDiP) system are assessed for a regional transport aircraft (RTA). With near term motor technology, an improvement in trip fuel burn was observed on the four and six propeller variants of the TEDiP aircraft. The takeoff field length(TOFL) also improved in all three design variants …

Design Optimization of a Regional Transport Aircraft with Hybrid Electric Distributed Propulsion Systems
… technology restricts its adoption for commercial transport aircraft. A Hybrid Electric Distributed Propulsion (HEDiP) system offers a promising alternative to the all-electric system. It leverages the benefits of DEP when coupled with a hybrid electric system. One of the areas needing improvement …

Air Pollutant Concentrations and Trends over the Eastern U.S. and China: Aircraft Measurements and Numerical Simulations
… of the air pollutant column contents and the regional transport in the free troposphere. Analyses of the historical data indicated ~2.0 Dobson Unit/decade decrease in tropospheric O3 columns over the eastern U.S. with a similar decreasing trend of CO. The statistical analysis also showed a …

Acting in Time: Transport Nurses optimising critically ill patients for transfer to a regional ECMO centre. A Grounded Theory Study
Regionalisation and centralisation of Intensive Care Units, coupled with demographic changes, have resulted in an increased demand for inter-hospital transport. The Conventional ventilatory support vs Extracorporeal membrane oxygenation for Severe Adult Respiratory Failure Trial (CESAR), validated …

Urban sprawl: land-use, travel behaviours, and emissions in Ireland
… of human activities across space while transport infrastructure determines the ability of goods, services, and people to travel across this space. Considering this relationship, it is important to understand how these mechanisms interact, but also how they can contribute to efforts to …

Piloting an open-source Transport Justice Tool for Southern Africa
Traditional transport planning methods largely promote transport-related social exclusion in favour of existing travel patterns. The monetary valuation of travel time savings (biased towards projects that serve higher income earners), thus generates more overall benefits and focus of alleviating …
