  1. 1. Modelling tools for quieter vehicles : Waves in poro– and visco–elastic continua

    Författare :Martin Östberg; Leif Kari; Jenny Jerrelind; Sergey Sorokin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vibro-acoutics; poro-elastic; visco-elastic; reduced models; Harmonic expansion; wave guide;

    Sammanfattning : New modelling tools intended to contribute to the development of components for quieter vehicles are developed. The tools are based on continuum models for wave propagation in poro– and visco–elastic media. By using geometric attributes of the studied components, the computational cost may be radically decreased compared to traditional methods. LÄS MER

  4. 3. The Political Dimension of Place Branding

    Författare :Andrea Lucarelli; Per Olof Berg; Jacob Östberg; Martin Kornberger; Dominique Bouchet; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; politics; ecology; place branding; policy; positioning; ideology; biopolitical; complexity; spatio-temporal; företagsekonomi; Business Administration;

    Sammanfattning : Place branding is commonly understood as the application of marketing and commercial ideas, strategies, measurements and logic to the realm of places such as cities, regions and nations. Nevertheless, place branding is also understood as the locus where political activities – imbued with political impact and political effects – appear and affect the soft and hard infrastructures of urban agglomeration and other spatial environments.
