11. Spark Ignition Combustion of Direct Injected Alternative Fuels
Sammanfattning : Several technologies and modifications exist to increase the fuel efficiency of passenger vehicles in general and spark ignition engines in particular. Combining a spark ignition engine with an electric drive system in hybrid powertrain and thermodynamic cycle improvements are two such approaches with the potential to greatly reduce fuel consumption.

12. Numerical Modeling of Turbulent Combustion and Flame Spread
Sammanfattning : Theoretical models have been developed to address several important aspects of numerical modeling of turbulent combustion and flame spread. The developed models include a pyrolysis model for charring and non-charring solid materials, a fast narrow band radiation property evaluation model (FASTNB) and a turbulence model for buoyant flow and flame.

13. Emissions from Fires Consequences for Human Safety and the Environment
Sammanfattning : Accidental fires represent a risk for people from the heat and fire effluents produced. It is clear from fire statistics that it is, in fact, the toxic gases that kill and injure many fire victims. Further, there are a number of compounds that are readily produced in fires, which have important sublethal effects on humans. LÄS MER
14. Aspects of regeneration in tropical secondary forests of Northeast Borneo affected by selective logging, El Niño-induced drought and fire
Sammanfattning : A large proportion of the world´s tropical rainforests are today secondary forests, a term encompassing forests in various degrees of degeneration. For the main traits of old-growth forests´ structures, species composition and ecosystem functions to recover, regeneration of non-pioneer tree species is essential. LÄS MER
15. Essays on Firms’ Hiring, Investment and Risk Management Decisions
Sammanfattning : This thesis contains five self-contained chapters. In “The Effect of Centrally Bargained Wages on Firm Growth”, the author studies how firms adjust their hiring and investments in response to higher collectively bargained wage increases. Firms absorb labor cost shocks by increasing sales growth. LÄS MER
