1. 1. Steel-to-timber dowel joints : Influence of moisture induced stresses

   Författare :Johan Sjödin; Hans Petersson; Carl-Johan Johansson; Per-Johan Gustavsson; Växjö universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; constraint stresses; contact-free measurement; dowel-type joints; humidity variations; moisture-induced deformations; timber structures; Building engineering; Byggnadsteknik; Byggteknik; Civil engineering;

   Sammanfattning : Joints are critical parts of timber structures, transmitting static and dynamic forces between structural members. The ultimate behavior of a loaded building depends strongly on the structural configuration and the capacity of the joints. LÄS MER

3. 2. Development of soft sensors for monitoring and control of bioprocesses

   Författare :Robert Gustavsson; Carl-Fredrik Mandenius; Johan Hyllner; Carl Johan Franzén; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In the manufacture of bio-therapeutics the importance of a well-known process is key for a high product titer and low batch to batch variations. Soft sensors are based on the concept that online sensor signals can be used as inputs to mathematical models to derive new valuable process information. LÄS MER

4. 3. Modal Dynamics of Vertical-Cavity Surface-Emitting Lasers

   Författare :Johan Gustavsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transverse modes; noise; modeling; Semiconductor laser; dynamics; vertical-cavity surface-emitting laser;

   Sammanfattning : In this work, a comprehensive dynamic model has been developed for simulating a novel semiconductor laser type, referred to as the Vertical-Cavity Surface-Emitting Laser (VCSEL). The high-speed behavior was simulated and compared to experiments, where excellent agreement was found. LÄS MER

7. 5. Treacherous Liberties : Isaiah Berlin's Theory of Positive and Negative Freedom in Contemporary Political Culture

   Författare :Gina Gustavsson; Li Bennich-Björkman; Johan Tralau; Karl-Oskar Lindgren; David Miller; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; freedom; liberty; values; autonomy; authenticity; tolerance; liberalism; permissiveness; Romanticism; Enlightenment; diversity; Inglehart; political culture; civicness; factor analysis; Statskunskap; Political Science;

   Sammanfattning : Contemporary attitudes in affluent Western societies are characterised by a growing emphasis on individual freedom. What, then, does this commitment to liberty entail for our openness to diversity; and ultimately for liberal democracy? Previous research on popular attitudes, for example by Ronald Inglehart, tends to assume that valuing freedom entails an encouragement of a plurality of life-styles. LÄS MER
