2. 1. Time and Frequency Transfer using Passive Techniques in Active Fiber Optic Networks

   Author : Sven-Christian Ebenhag; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber link; optical fiber.; Global positioning system GPS ; fiber network; time transfer; two-way; synchronous optical networking SONET synchronous digital hierarchy SDH ; GPS carrier phase;

   Abstract : For the modern society, high precision time and frequency transfer have become crucial since a large number of systems, such as telecommunication systems, require precise and stable synchronization. Electric power companies use synchronized systems for taking stability measurements and searching for errors in their networks. READ MORE

4. 2. Simulations of the Dynamics of Fibre Suspension Flows

   Author : Stefan B Lindström; Tetsu Uesaka; Myat Htun; Fritz Bark; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fibre; fibre suspension; simulation; paper; papermaking; forming; fibre orientation distribution; fibre flexibility; viscosity; first normal stress difference; fluid flow; simple shear flow; two-way coupling; three-dimensional; Chemical engineering; Kemiteknik; Engineering physics; Teknisk fysik;

   Abstract : A new model for simulating non-Brownian flexible fibres suspended in a Newtonian fluid has been developed. Special attention has been given to include realistic flow conditions found in the industrial papermaking process in the key features of the model; it is the intention of the author to employ the model in simulations of the forming section of the paper machine in future studies.

5. 3. CCTV, Live and Videotapes: How Presentation Mode Affects the Evaluation of Witnesses

   Author : Sara Landström; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Presentation Mode; Live; Video; Two-way CCTV; Deception Detection;

   Abstract : Videotaped and closed circuit testimonies are often used in legal procedures, but little is known about the psychological effects of these courtroom technologies. The present thesis examines how different presentation modes affect observers’ perception, veracity assessment and memory. READ MORE

6. 4. Trust, risk and vulnerability : towards a philosophy of risk communication

   Author : Madeleine Hayenhjelm; Sven Ove Hansson; Ingar Brinck; KTH; []
   Keywords : HUMANIORA; HUMANITIES; Risk communication; two-way communication; democratic approach; equality; asymmetry; vulnerability; trust; Philosophy subjects; Filosofiämnen;

   Abstract : This thesis is a philosophical contribution to the theories on risk communication. The topic of risk communication is approached from several different angles, but with a normative focus on equality and vulnerability. Essay I is a comment on risk perception theory and the psychometric model in particular. READ MORE

7. 5. Model predictions of turbulent gas-particle shear flows

   Author : Tobias Strömgren; Gustav Amberg; Arne V. Johansson; Martin Sommerfeld; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent gas-particle flows; modelling; turbophoresis; two-way coupling; particle-particle collisions; numerical simulations; Fluid mechanics; Strömningsmekanik;

   Abstract : A turbulent two-phase flow model using kinetic theory of granularflows for the particle phase is developed and implmented in afinite element code. The model can be used for engineeringapplications. However, in this thesis it is used to investigateturbulent gas-particle flows through numerical simulations. READ MORE
