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

    Författare :Mats Haglund; Nils Petter Gregersen; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Driving behaviour; Speed choice; Risk estimates; Enforcement; Attitudes; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : 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. LÄS MER

  3. 2. Loyal Speed Adaptation Speed limitation by means of an active accelerator and its possible impacts in built-up areas

    Författare :Sverker Almqvist; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active accelerator; LSA; speed; speed reduction; driver behaviour; traffic safety; ISA; Teknik; Technological sciences; Road transport technology; Vägtransportteknik;

    Sammanfattning : Traditional measures for improved traffic safety need to be complemented by modern technologies in the struggle to reduce the consequences of traffic accidents all over the world. This thesis introduces the Loyal Speed Adaptation (LSA) function based on recent developments in the area of Intelligent Transport Sys-tems to support the vehicle drivers in not using inappropriate or excessive speeds, which have been found to be an important factor for causing serious and fatal accidents.

    Sammanfattning : For some years the new economy in Sweden was to a high extent represented by a couple of new and fast growing companies. One of these was the Internet consultancy Framfab (Framtidsfabriken). The company became synonymous with the unusual and exciting, a new kind of business, new products and new attitudes. LÄS MER

  5. 4. Predator psychology and mimicry evolution - a theoretical analysis

    Författare :Alexandra Balogh; Olof Leimar; Michael Speed; Stockholms universitet; []

    Sammanfattning : The evolution of Müllerian mimicry depends on many factors, among which predator psychology is the most important one. Predator avoidance learning, generalization and discrimination are primary selective agents during the evolutionary process. LÄS MER

  7. 5. High-resolution Studies of mRNA Expression in Brain : A Search for Genes Differently Expressed in Schizophrenia

    Författare :Anja Castensson; Elena Jazin; Terence Speed; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
