   Sammanfattning : 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. LÄS MER

4. 3. The Emergence of Markets for Technology : Patent Transfers and Patenting in Sweden, 1819–1914

   Författare :David E. Andersson; Fredrik Tell; Mats Larsson; Patricio Sáiz; Maureen McKelvey; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Patent transfers; patents; markets for technology; patent markets; patent agents; Business Studies; Företagsekonomi; Ekonomisk historia; Economic History;

   Sammanfattning : This thesis is concerned with the emergence of markets for technology and studies the evolution of patent transfers and its determinants, patent agencies and independent versus firm patenting in Sweden during the 19th century and the turn of 20th century. It explores how and why markets for technology emerge and under what circumstances by investigating the evolution of Swedish patent legislation and the patterns of patent transfers between individuals and firms.

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

   Författare :Sarah Tell; Raid Karoumi; Andreas Andersson; Ülker-Kaustell Mahir; José Maria Goicolea; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 5. Omvälvningarnas tid: Handelshuset Ekman i Göteborg på en europeisk kreditmarknad 1790–1820

   Författare :Magnus Andersson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : The purpose of this doctoral dissertation is to chart and analyze the flow of payments and credits to and from Gothenburg for the period 1790−1820, with a special interest in the transactions involving The Merchant House Ekman & Co. Both bills of exchange transactions within Ekman & Co and protested bills of exchange for other firms are studied. LÄS MER
