  1. 6. Slip and fall risk on ice and snow : identification, evaluation and prevention

    Författare :Chuansi Gao; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

    Sammanfattning : Slip and fall accidents and associated injuries on ice and snow are prevalent among outdoor workers and the general public in winter in many regions of the world. To understand and tackle this multi-factorial problem, a multidisciplinary approach was used to identify and evaluate slip and fall risks, and to propose recommendations for prevention of slips and falls on icy and snowy surfaces.

  3. 7. Synthesis of a Model-based Tire Slip Controller

    Författare :Stefan Solyom; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LMI; synthesis; hybrid; piecewise linear; ABS; PID;

    Sammanfattning : The Anti-lock Braking System (ABS) is an important component of a complex steering system for the modern car. In the latest generation of brake-by-wire systems, the performance requirements on the ABS have changed. The controllers have to be able to maintain a specified tire slip for each wheel during braking. LÄS MER

  4. 8. The effect of anti-slip devices on pedestrian safety : method development and practical test

    Författare :Glenn Berggård; Christer Hydén; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Engineering; Trafikteknik;

    Sammanfattning : Every winter, more than 100,000 pedestrians in the Nordic countries receive medical treatment as a result of falls on slippery surfaces. In addition, the risk of injury reduces interest in outdoor activities during the wintertime. LÄS MER

  5. 9. Performance of Stress-Laminated-Timber Bridge Decks

    Författare :Kristoffer K J Ekholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; butt joints; non-linear modelling; stress-laminated timber; linear modelling; prestressing; timber bridges; interlaminar slip; FE modelling; laboratory tests; durability;

    Sammanfattning : Stress-laminated-timber (SLT) bridge decks are a satisfactory alternative to conventional short-span bridges in terms of cost and performance. SLT decks are made from a number of timber or glulam beams positioned side by side and stressed together using high-strength steel bars. LÄS MER

  7. 10. Multiscale Modelling of Reinforced Concrete Structures

    Författare :Adam Sciegaj; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cracking; reinforced concrete; computational homogenisation; bond-slip; multiscale;

    Sammanfattning : Concrete cracks at relatively low tensile stresses; cracks open up for ingress of harmful substances, negatively affecting the durability of reinforced concrete structures. Crack widths are thus limited in the design codes, and accurate predictions are needed, especially for large reinforced concrete structures such as bridges or nuclear reactor containment buildings.
