Sammanfattning : Achieving upcoming emissions legislation (Euro VI) for heavy trucks is a serious challenge for the manufacturers. Apart from the increasingly strict limits on nitrogen oxides (NOx) and particulate emissions (PM), the limited amount of fossil fuels as well as alarming climate changes simultaneously drives the demand for low CO2 emissions.

Sammanfattning : In the oil refinery industry, companies need to have a high utilization of production, storage, and transportation resources to be competitive. This can only be achieved by proper planning The purpose of this thesis is to contribute to the development of optimization models and solution methods that support the scheduling and planning at refinery companies.

Sammanfattning : The work presented in this thesis is motivated by the need to reliably operate a compression-ignition engine in a partially premixed combustion (PPC) mode. Partially premixed combustion is a low temperature combustion concept, where the ignition delay is prolonged to enhance fuel-air mixing in the combustion chamber before the start of combustion.

Sammanfattning : This thesis studies and develops copula-based portfolio optimization. The overall purpose is to clarify the effects of copula modeling for portfolio allocation andsuggest novel approaches for copula-based optimization. The thesis is a compilation of five papers. LÄS MER
5. Towards Model-Based Development of Self-Managing Automotive Systems : Modeling, Simulation, Model Transformations and Algorithms: Supporting the Development of the DySCAS Middleware
Sammanfattning : With the increased usage of electronics, embedded computer systems, software and networks in modern vehicles, the complexity is also increasing in terms of the development process, functionalities as well as their implementation. On one hand there is a need for efficient and systematic development, and on the other hand the systems are required to have enhanced post-deployment time configuration management support. LÄS MER
