1. 1. Transition in Particle-laden Flows

   Författare :Joy Klinkenberg; Luca Brandt; Shuisheng He; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition; modal analysis; non-modal analysis; multi-phase flow; particle-laden; heavy particles; light particles;

   Sammanfattning : This thesis presents the study of laminar to turbulent transition of particle laden flows. When a flow becomes turbulent, the drag increases one order of magnitude compared to a laminar flow, therefore, much research is devoted to understand and influence the transition. LÄS MER

3. 2. Foreign Investment Decision-Making in Transition Economies

   Författare :Olga Golubeva; Julio De Castro; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; FDI; transition economy; initial motivation or reasons for FDI; capital budgeting methods and investment decision criteria; investigation of investment climate and information collection methods; risk assessment and risk reduction measures; decision-making models; case studies; survey method; Politics; Economy and the Organization of Society; Politik; ekonomi och samhällets organisering; Östersjö- och Östeuropaforskning; Baltic and East European studies; företagsekonomi;

   Sammanfattning : The purpose of this project is to describe and explain the foreign investment decision process in the uncertain and turbulent environment of transition economy. By getting an in-depth understanding of how decision-making works in the environment of transition economy, the study intends to contribute to the development of business administration theory in the area of foreign investment decision-making, particularly its application in the turbulent and uncertain world.

4. 3. Thermodynamic investigations of transition metal systems containing coabon and nitrogen

   Författare :Lidong Teng; Seshadri Seetharaman; Tooru Matsumiya; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; thermodynamic activity; galvanic cell technique; transition metal carbides; transition metal nitrides; phase equilibrium; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : In view of the important applications of carbides and carbo-nitrides of transition metals in the heat-resistant and hard materials industries, the thermodynamic activities of Cr and Mn in the Cr-C, Fe-Cr-C, Mn-Ni-C and Mn-Ni-C-N systems have been studied in the present work by the use of the galvanic cell technique. CaF2single crystals were used as the solid electrolyte. LÄS MER

5. 4. On estimation in econometric systems in the presence of time-varying parameters

   Författare :Kurt Brännäs; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Econometric systems; time-varying parameters; Kalman filtering; stochastic regressors; unknown transition matrix; robustness; simulation;

   Sammanfattning : Economic systems are often subject to structural variability. For the achievement of correct structural specification in econometric modelling it is then important to allow for parameters that are time-varying, and to apply estimation techniques suitably designed for inference in such models.

7. 5. Nonlinear dynamics and smooth transition models

   Författare :Andrés González Gómez; Handelshögskolan i Stockholm; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : During the last few years nonlinear models have been a very active area of econometric research: new models have been introduced and existing ones generalized. To a large extent, these developments have concerned models in which the conditional moments are regime-dependent. LÄS MER
