  1. 6. Conductive Fabrics for Textile Electronic Interconnections and Capacitive Sensing - A Smart Textiles Perspective

    Författare :Emanuel Gunnarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Smart textiles offer ways to integrate sensing and actuating abilities into textile structures found in garments, furniture and other applications such as filters, reinforcements, disposable products and others. A large part of the research being done on smart textiles concerns the possibilities for monitoring human health and wellbeing. LÄS MER

  3. 7. Robust self-localization of mobile robots in dynamic environments using scan matching algorithms

    Författare :Ola Bengtsson; Christian Schlegel; Chalmers tekniska högskola Göteborg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobile robot; Self-localization; Scan matching algorithm; Changed environments; Dynamic environments; o-variance matrix; Kalman filter; Signal processing; Signalbehandling;

    Sammanfattning : The most fundamental task for any mobile robot is to perform self-localization in the world in which it is currently active, i.e. determine its position relative its world. Encoders that count wheel rotations are often used, which can be turned into relative position estimates by mean of integration. LÄS MER

  4. 8. Aggregating Case Studies of Vehicle Crashes by Means of Causation Charts : An Evaluation and Revision of the Driving Reliability and Error Analysis Method

    Författare :Jesper Sandin; Per Lövsund; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Accident; Cause; Classification; Characteristics; Driver; Error; 81 Road: Accidents; 81 Road: Accidents; 841 Road: Road user behaviour; 841 Road: Road user behaviour;

    Sammanfattning : There is a need for increased knowledge about causes to motor-vehicle crashes and their prevention. Multidisciplinary in-depth case studies can provide detailed causation data that is otherwise unattainable. Such data might allow the formulation of hypotheses of causes and causal relationships for further study. LÄS MER

  5. 9. Safety as a process : From risk perception to safety activity

    Författare :Christina Stave; Tore J Larsson; Institutionen för produkt- och produktionsutveckling Chalmers Tekniska Högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Accident prevention; Occupation; Risk; Perception; Safety; Food; Industry; V Medicine; V Medicine; Oha Labour and labour market; Oha Labour and labour market;

    Sammanfattning : The frequency of occupational accidents in the Swedish food industry and agriculture is high. This thesis has therefore explored the 'process of safety' in order to detect and analyse factors that either hinder or facilitate safety activity and to further develop intervention methods towards increased safety activity.

  7. 10. Influence of combined thermal and mechanical loadings on pearlitic steel microstructure in railway wheels and rails

    Författare :Dimitrios Nikas; 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; Low cycle fatigue LCF ; Wheel steels; Hardness; TEM; Thermal effects; EBSD; Rail steels; Pearlite; Multiaxial fatigue; Spheroidisation; Materials Science;

    Sammanfattning : One of the most important aspects in railway operation is the interaction between rail and wheel. The contact patch between these two components is around the size of a small coin, and since high loads act on this small area, stresses will give rise to wear and damage in both components. LÄS MER
