  2. 16. Some aspects of the dynamic soil-structure interaction of a portal frame bridge

    Author : Mahir Ülker-Kaustell; Raid Karoumi; Mohammed Hjiaj; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

    Abstract : For certain bridge types, the influence of soil-structure interaction (SSI) may have an important contribution to the stiffness and damping of the structural system. From a design point of view, this influence may be both conservative and non-conservative and therefore, an increased knowledge within this field could lead to better design assumptions. READ MORE

  4. 17. Towards Novel AlGaN-Based Light Emitters

    Author : Martin Stattin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AlGaN; light emitting diode; deep ultraviolet; III-Nitrides; near infrared; quantum cascade laser;

    Abstract : The unique properties of the AlGaN semiconductors make them a suitable choice for optoelectronic devices at both short and long wavelengths, based on interband and intersubband transitions, respectively. What sets AlGaN apart from other wide-bandgap semiconductors is the possibility to obtain both p- and n-type conductivity as well as the direct bandgap. READ MORE

  5. 18. Regional public transport : The balancing act of service planning

    Author : Joel Hansson; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public transport; Network planning; Regional bus; Regional rail; Rural accessibility; Service planning; Trade-offs;

    Abstract : This thesis addresses the demand for more knowledge regarding regional public transport (between urban areas or to and from rural areas). More specifically, the aim is to develop a better understanding of the effects of different service planning decisions in terms of different trade-offs and their impacts on the overarching objectives of public transport provision.

  6. 19. Exploring the Hidden Dimensions of Distraction in Adults with Atypical Attention

    Author : Pia Elbe; Jessica Körning-Ljungberg; Daniel Sörman; Mariana Vega Mendoza; Lars Nyberg; Henrik Danielsson; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; attention; distraction; ADHD; cognition; Psychology; Psykologi;

    Abstract : Inattention and proclivity for distraction are symptoms of adult ADHD that hamper productivity in study and work environments. The topic of this dissertation is mechanisms of distraction and facilitation of attention in ADHD. This thesis includes three studies. READ MORE

  7. 20. Understanding processes and travel behaviour changes connected to electric vehicle adoption

    Author : Joram H.M. Langbroek; Joel P. Franklin; Yusak Susilo; Jilian Anable; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

    Abstract : The use of electric vehicles (EVs) has the potential to increase the sustainability of the transport system, especially in case of unchanged or decreased car use, eco-driving and charging during hours of low electricity demand in case of an electricity generation mix with a large share of renewable energy sources. However, EVs still use much energy and EV-use does not solve problems regarding accessibility, social equity, traffic safety and has only a limited beneficial effect on liveability (e. READ MORE
