  2. 1. Winter maintenance and cycleways

    Author : Anna Bergström; KTH; []
    Keywords : cycleways; winter maintenance; maintenance service level; mode choice; winter cycling frequency; winter road condition assessment; bicycle measurements; friction measurement; winter maintenance equipment;

    Abstract : Increasing cycling as a means of personal travel couldgenerate environmental benefits if associated with acorresponding decrease in car-based transport. In seeking topromote cycling in wintertime, it is desirable to understandhow important the road surface condition is compared to otherfactors in people's decision to cycle or not. READ MORE

  4. 2. Urban design of winter cities : Winter season connectivity for soft mobility

    Author : David Chapman; Kristina Nilsson; Agatino Rizzo; Agneta Larsson; Dag Kittang; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban form; urban design; seasonal climate variation; winter cities; climate change; Architecture; Arkitektur;

    Abstract : All across the world the form of the built environment is playing a crucial role as enabler or inhibitor for urban outdoor activity such as soft mobility. Urban form can make it more attractive for people to be mobile outdoors and playing a role in the public life, or it can put people off venturing outside. READ MORE

  5. 3. Motion Perception and Tire Models for Winter Conditions in Driving Simulators

    Author : Artem Kusachov; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle dynamics; winter conditions; tire model; motion perception; winter driving simulation;

    Abstract : Many traffic accidents happen due to winter conditions, like slippery roads and limited visibility. The road administrators put a lot of effort into snow removal and deicing the roads. The vehicle manufacturers have been working with functionality to support drivers in winter conditions (studded tires, ABS, ESC, etc.) for decades. READ MORE

  6. 4. Salmonid behaviour under winter conditions

    Author : Johan Watz; Larry Greenberg; Eva Bergman; John Piccolo; Richard Cunjak; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate change; drift; energy budget; foraging; grayling; ice cover; lotic; metabolic rate; predation; salmon; stream; stress; temperature; trout; Biology; Biologi;

    Abstract : Winter conditions are believed to play an important role in the population dynamics of northern temperate stream fish, challenging the ability of fish to physiologically and behaviourally adapt. Climate change is predicted to increase both mean temperature and temperature fluctuations, especially during winter, leading to dynamic environmental conditions in terms of river ice production and flow.

  7. 5. Tools for characterizing performance degradation in lithium-ion batteries

    Author : Alexander J. Smith; Rakel Wreland Lindström; Göran Lindbergh; Pontus Svens; Martin Winter; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : Lithium-ion batteries have enabled vast societal changes, ranging in scale from the adoption of personal electronics to electromobility and grid-scale, renewable energy storage. However, all applications face performance fade over time, observed as losses of battery capacity and power. READ MORE
