Co-design is a participatory approach that seeks to increase end users’ involvement in designing products and services. However, there is a lack of active participation by young people in the design of tobacco control health communication, especially in African countries. This thesis ha...

Rebuilding cities after conflict often prioritizes political or economic interests at the expense of long-term resilience, equity and inclusion. Post-war recovery must break away from traditional, interest-driven patterns. Instead, reconstruction should be redefined through a science-driven, multidisciplinary l...

This thesis presents a novel approach to design and implement a new channel coding method combined with a Adaptive RIS (ARIS) to enhance Terahertz (THz) communication in 6G networks. The research addresses the crucial requirements of 6G communication, including ultra-fast data transmission,&...

Solar photovoltaic (PV) systems are currently seen as an affordable and mainstream renewable energy option to support energy decarbonisation, aligning with commitments of the UN Sustainable Development Goals (SDG 7). This technology prevails in high irradiance places such as deserts, where s...

Ammonia is a promising zero-carbon fuel for internal combustion engines; however, its low laminar flame speed makes lean combustion highly sensitive to turbulence and flame development. In this study, an entrainment-based two-zone combustion model is developed for hydrogen-enriched ammonia spark-ignit...

Heat recovery systems (HRS) exist in conceptual configurations which encompass a set of energy-using processes installed on a particular site, a set of waste heat recovery technologies and all potential recirculation of material and energy streams with the overall aim to generate an...

Do shifts into high stock-market volatility foreshadow recessions rather than merely accompany them? Prior work shows volatility rises in downturns and can help short-horizon forecasts, but the timing of discrete volatility regime changes relative to business-cycle turning points is less understo...
