  1. 1. Bullying and social objectives : A study of prerequisites for success in Swedish schools

    Författare :Björn Ahlström; Jonas Höög; Roine Johansson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Successful schools; Social objectives; Leadership; Bullying; Insulting behaviour; Sociology; Sociologi; sociologi; Sociology;

    Sammanfattning : This thesis examines the relationship between organizations structure, culture and leadership. The specific organization that has been studied is Swedish secondary schools. The Swedish schools have a divided task, first to develop the students academic skills and secondly to develop the students socially and civically. LÄS MER

  3. 2. Hållbarhetens mänskliga byggstenar - om betydelsen av engagerade tjänstemän i det lokala miljömålsarbetet

    Författare :Kerstin Bartholdsson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; public administration; implementation; steering by objectives; civil servant; environmental attitudes; environmental objectives; fiery spirit;

    Sammanfattning : Abstract This thesis focuses on the municipal civil servant’s role in local environmental work. The overall purpose is to increase knowledge about personal involvement in the role of the civil servant and indeed to contribute to existing theory on the significance of enthusiastic persons in carrying out political decisions.

  4. 3. Haptic Feedback Control Methods for Steering Systems

    Författare :Tushar Chugh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; passivity and coupled stability; torque and position overlay; Haptic feedback; impedance and admittance control; system identification; steering system;

    Sammanfattning : Haptic feedback from the steering wheel is an important cue that defines the steering feel in the driver-vehicle interaction. The steering feedback response in an electric power assisted steering is primarily dependent on its control strategy. LÄS MER

  5. 4. Driver-centred Motion Control of Heavy Trucks

    Författare :Kristoffer K D Tagesson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver behaviour; active safety; torque feedback; heavy trucks; motion coordination; steering by braking; oncoming collision; electronic stability control; active steering;

    Sammanfattning : Traffic accidents constitute one of the leading global causes of death. Deadly traffic accidents occur, even in countries that have implemented far-reaching countermeasures, at a rate that cannot be tolerated. Improved safety of heavy trucks is an important remedy, as these vehicles are involved in a large part of all fatal accidents. LÄS MER

  7. 5. Steering control for haptic feedback and active safety functions

    Författare :Tushar Chugh; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; position control; coupled stability; passivity; steering system; uncoupled stability; transparency; active safety; haptic feedback; torque control; state estimation;

    Sammanfattning : Steering feedback is an important element that defines driver–vehicle interaction. It strongly affects driving performance and is primarily dependent on the steering actuator's control strategy. LÄS MER
