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

    Author : Mats Haglund; Nils Petter Gregersen; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Psychology; Driving behaviour; Speed choice; Risk estimates; Enforcement; Attitudes; Psykologi; Psychology; 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. High-resolution Studies of mRNA Expression in Brain : A Search for Genes Differently Expressed in Schizophrenia

    Author : Anja Castensson; Elena Jazin; Terence Speed; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; mRNA; gene expression; real-time RT-PCR; schizophrenia; 5-HT serotonin receptor 2C; brain; psychiatric genetics; Genetik; Clinical genetics; Klinisk genetik;

    Abstract : Gene expression differences between patients and controls can be used to find susceptibility genes and drug targets for a disease. High-resolution strategies are required because the differences between the investigated groups may be small and numerous factors may affect the mRNA quantity. READ MORE

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

    Author : Oskar Fröidh; KTH; []
    Keywords : 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.

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

    Author : Mikael Razola; Jakob Kuttenkeuler; Anders Rosén; Olav Fredrik Rognebakke; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

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

    Author : Robert Lewén; KTH; []
    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
