1. Dual-Fuel Combustion in a Heavy-Duty Engine
Sammanfattning : The need to control climate change and improve the fuel effieciency of internal combustion engines has prompted global efforts to develop alternative fuels in order to reduce dependence on conventional petroleum derivatives. This thesis deals with three such alternative fuels: compressed natural gas (CNG), pure methane (used to mimic biogas), and methanol. LÄS MER
2. Processes of long-term coastal evolution and their mathematical modelling : Application to the Mozambican coast
Sammanfattning : Different processes in response to the action of natural driven forces and the human interference on coastal systems act together, contributing to shape the coast. Coastal evolution models have been developed as useful tools to better understand the contribution of different processes on observed coastal changes, and also to anticipate future evolution in response to different actions and interventions taking place along the coast.

3. Model-based Approaches to Privacy Compliance
Sammanfattning : In the last decade, information technologies have been developing dramatically, and therefore data harvested via the Internet is growing rapidly. This technological change has a negative impact on privacy due to the sensitivity of the data collected and shared without convenient control or monitoring. LÄS MER
4. Experimental study of a Volatiles Distributor for Improving the Cross-sectional Gas Distribution in Fluidized Beds
Sammanfattning : Chemical looping combustion (CLC) is a promising carbon capture technology due to its inherent CO2 separation. Significant progress has been made in CLC of solid fuels in recent years. LÄS MER
5. Solar heat pump systems for heating applications : Analysis of system performance and possible solutions for improving system performance
Sammanfattning : Solar heat pump systems (SHPs) are systems that combine solar energy and heat pumps. SHPs have been investigated for several decades and have been proven to increase the share of renewable energy and reduce electric energy demand in residential heating applications. LÄS MER
