   Author : Sarah Tell; Raid Karoumi; Ülker-Kaustell Mahir; Andreas Andersson; Bill F. Jr. Spencer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamics; vibration mitigation; railway bridge; high-speed trains; bridge deck acceleration; passive damping; fluid viscous dampers; retrofit; dynamik; vibrationsdämpning; järnvägsbro; höghastighetståg; brobaneacceleration; passiv dämpning; viskösa dämpare; eftermontering; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : At the moment of writing, an expansion of the Swedish railway network has started, by constructions of new lines for high-speed trains. The aim is to create a high-speed connection between the most populous cities in Sweden - Stockholm, Göteborg and Malmö, and the rest of Europe. READ MORE

5. 3. High speed CMOS optical receiver

   Author : Håkan Bengtson; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Optical communication develops very fast and is today the main method for long distance wired communication. However cost is still high. Looking back to the evolution of optical transmission systems, one main objective of system development has become more and more important; minimize cost per gigabytes per second per kilometre, Gb/s/km.

6. 4. Vibration mitigation of high-speed railway bridges : Application of damping devices in theory and practice

   Author : Sarah Tell; Raid Karoumi; Andreas Andersson; Ülker-Kaustell Mahir; José Maria Goicolea; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration mitigation; high-speed railway bridges; damping devices; retrofit; numerical analysis; hybrid simulation; field experiment; vibrationsdämpning; järnvägsbroar för höghastighetståg; dämpare; eftermonteringsmetod; numerisk analys; hybridsimulering; fältförsök; Structural Engineering and Bridges; Bro- och stålbyggnad;

   Abstract : The dynamic response of railway bridges is an important aspect to consider, as the repetitive loading from passing trains may result in excessive vibrations of the bridge deck. Several design criteria are developed in order to assure the structural safety and passenger comfort during train crossings of a bridge. READ MORE

7. 5. Simplified dynamic analysis of railway bridges under high-speed trains

   Author : Christoffer Johansson; Costin Pacoste; Raid Karoumi; Jose M Goicolea; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic; Railway bridge; High-speed train; Moving load; Multi-span beam; Probabilistic;

   Abstract : The world-wide development of new high-speed rail lines has led to more stringent design requirements for railway bridges. This is mainly due to the fact that a train at high speeds can cause resonance in the bridge superstructure. READ MORE
