2. 1. CALIBRATION OF CHROMATOGRAPHY MODELS

   Author : Patrik Persson; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; film mass transfer resistance; Kemiteknik och kemisk teknologi; sorption kinetics; external volume; monolithic bed; shallow bed; packed bed; capillary model; detailed model; computer simulation; parameter estimation; diffusion; model calibration; Chromatography; modelling; proteins; Chemical technology and engineering;

   Abstract : AbstractThis thesis is devoted to calibration of mathematical chromatography models. Chromatography models include unknown parameters that must be determined before the models can be applied to optimization or scale-up of a chromatography process. READ MORE

4. 2. Model-driven Alignment : Linking Business Strategy with Information Systems

   Author : Constantinos Giannoulis; Jelena Zdravkovic; John Krogstie; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Alignment; Business; Strategy; Information; Systems; Requirements; IS; Enterprise; Models; Modeling; Computer and Systems Sciences; data- och systemvetenskap;

   Abstract : Information technology (IT) is more pervasive than ever before, constituting a significant factor for performance and survival in the business arena. It is essential that IT within organizations understands what the Business needs in order to provide the necessary support and bring value, which is also true when IT is also the main value creator.

5. 3. The Black-Litterman Model : mathematical and behavioral finance approaches towards its use in practice

   Author : Charlotta Mankert; Birger Ljung; Ted Lindblom; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Black-Litterman Model; Portfolio Management; Portfolio Theory; Portfolio Models; Behavioral Finance; Business and economics; Ekonomi;

   Abstract : The financial portfolio model often referred to as the Black-Litterman model is analyzed using two approaches; a mathematical and a behavioral finance approach. After a detailed description of its framework, the Black-Litterman model is derived mathematically using a sampling theoretical approach. READ MORE

6. 4. Cluster model of disordered systems : application to doped semiconductors and a simple model polymer

   Author : Rolf G. Riklund; Linköpings universitet; []
   Keywords : ;

   Abstract : In this thesis we study with an extended cluster model calculation the combined effect of disorder and electron-electron interaction on the electronic structure of doped semiconductors and a simple model polymer chain. First a one-band model using a Hartree calculation is compared to other authors result for the impurity band using less realistic Hamiltonians. READ MORE

7. 5. Full Cycle Engine Simulations with Detailed Chemistry

   Author : Adina Gogan; Värmeöverföring; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasmas; Gaser; Gases; fluid dynamics; aktuariematematik; programmering; operationsanalys; Statistik; actuarial mathematics; programming; operations research; Statistics; detailed kinetics; emissions; engine knock; autoignition; modeling; spark ignition engine; diesel engine; fluiddynamik; plasma; Technological sciences; Teknik; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; Motors and propulsion systems; Motorer; framdrivningssystem; stochastic reactor model;

   Abstract : The modeling work developed in this thesis can be divided in two main areas of investigations: autoignition related to spark ignition engine and combustion and emissions formation in relation to diesel engines. A first version of a detailed kinetics engine simulation program, extended to handle full cycle calculations, was employed in order to demonstrate the strong effect that nitric oxide from the residual gas has on the autoignition onset.
