  1. 1. Speed Choice The Driver, the Road and Speed Limits

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mats Haglund; Uppsala universitet.; [2001]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Driving behaviour; Speed choice; Risk estimates; Enforcement; Attitudes; Psykologi; SOCIAL SCIENCES Social sciences Psychology; SAMHÄLLSVETENSKAP Socialvetenskap Psykologi; Psychology; psykologi;

    Abstract : Speed choice is one of the more characteristic features of driver behaviour. The speed a driver chooses to travel at determines the degree of difficulty he or she operates under. Higher speeds lead to more accidents, higher accident risk and more severe consequences of an accident. READ MORE

  2. 2. Introduction of regional high speed trains A study of the effects of the Svealand line on the travel market, travel behaviour and accessibility

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Oskar Fröidh; KTH.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; The Svealand line; high speed trains; regional travel; travel behaviour; choice of transport mode; accessibility; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The Svealand line opened in 1997 and the services areoperated with regional high speed trains. While the Svealandline was being built, the slow trains that had been inoperation on the old railway between Eskilstuna and Stockholm(a distance of 115 km) were replaced by buses with a highfrequency of service.

  3. 3. On Structural Design of High-Speed Craft

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mikael Razola; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slamming; high-speed craft; finite-element analysis; design methods; experimental analysis; numerical simulations; design loads; statistical analysis;

    Abstract : The development in structural design and construction of high-speed craft has been extensive during the last decades. Environmental and economical issues have increased the need to develop more optimized structures, using new material concepts, to reduce weight and increase performance efficiency. READ MORE

  4. 4. High-Speed Electroabsorption Modulators and p-i-n Photodiodes

    University dissertation from Kista : Mikroelektronik och informationsteknik

    Author : Robert Lewén; KTH.; [2003]
    Keywords : Optical communication; Fiber optic; Electroabsorption modulators; p-i-n photodiodes; transmission line; traveling wave; high-speed; microwave photonics;

    Abstract : This thesis presents methods for optimization ofelectroabsorption modulators (EAM) and p-i-n photodiodes (PD)withrespect to high frequency (HF) performance. Differentreactive matching techniques are investigated such as lumpedmatching and integrated transmission line (TML) layouts includingoperation in the traveling-wave (TW) regime. READ MORE

  5. 5. Vibration mitigation of high-speed railway bridges Application of fluid viscous dampers

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Sarah Tell; KTH.; [2017]
    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; Civil and Architectural Engineering; Byggvetenskap;

    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
