1. PDEModelica – A High-Level Language for Modeling with Partial Differential Equations
Sammanfattning : This thesis describes work on a new high-level mathematical modeling language and framework called PDEModelica for modeling with partial differential equations. It is an extension to the current Modelica modeling language for object-oriented, equation-based modeling based on differential and algebraic equations. LÄS MER
2. On Modeling and Implementing Shopfloor Control Systems
Sammanfattning : One of the key factors that hold shopfloor control (SFC) software evolution back is the exorbitant cost, time, complexity, and inflexibility of developing customized SFC software solutions. The development and maintenance life-cycle of SFC software is characterized by lock-in problems. LÄS MER
3. Challenges in aero engine performance modeling
Sammanfattning : There is a continuous drive for ever more efficient aero engines due to environmental as well as economical concerns. As the technology of conventional turbofan engines matures, there is a need for new aero engine concepts as well as incremental improvement of existing technologies. LÄS MER
4. Hierarchical Modeling of Road Traffic Networks
Sammanfattning : The main objective of the thesis was to develop and applymethodologies for analysis and evaluation of the applicabilityof different types of road traffic simulation models for urbantraffic conditions. For this purpose a number of models ofmacroscopic, mesoscopic and microscopic type were applied,calibrated, validated and analyzed using extensive field datacollection to obtain traffic flow, travel time and queue-lengthdata for major road networks in Stockholm and Uppsala.

5. Analysis of Metabolites in Complex Biological Samples Using LC/MS and Multivariate Data Analysis : Metabolic Fingerprinting and Detection of Biomarkers
Sammanfattning : To facilitate early diagnosis of diseases and elucidation of the processes involved in their development and progression, various specific compounds or ‘biomarkers’ are often monitored. The first step is to decide which compounds to analyze. LÄS MER
