6. Control of Hybrid Electric Vehicles with Diesel Engines
Sammanfattning : This thesis is an approach to improve electric hybrid vehicles with respect to fuel consumption and to fulfil the future intended NOX emission regulations. It is based upon the conclusions made in the licentiate thesis Analysing Hybrid Drive System Topologies (Jonasson, 2002). LÄS MER
7. Renewable Energy in Energy-Efficient, Low-Pollution Systems
Sammanfattning : Energy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. LÄS MER
8. Mathematical Modelling in Catalytic Automotive Pollution Control
Sammanfattning : Design and control of honeycomb monolith reactors for catalytic automotive pollution control by mathematical modelling of the reactor has been studied. One aspect of the design has been that the use of metallic monolithic catalysts for automotive emission control raises certain optimization possibilities. LÄS MER
9. Dynamics of water pollution control : A regional evaluation
Sammanfattning : The 1970's saw a strong governmental backing of measures taken to improve surface water quality by reducing point-source emissions in Sweden. The aim of this thesis primarily was to evaluate the cost effectiveness of governmental strategies implemented to improve surface water quality and to study the relationship between policies adopted and current knowledge about different sources of pollution.

10. Stormwater Ponds for Pollution Reduction
Sammanfattning : Stormwater transports particulate-bound and soluble pollution from urban areas to receiving waters during rain events. Measurements have shown that open detention ponds, originally used for flood control, effectively reduce stormwater pollutant load and have therefore been increasingly used for stormwater treatment.
