  2. 1. Analysis of Dipole and Patch Antennas in Cylindrical Structures

    Author : Peter Slättman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fourier transform; cross-section; patch; slot; arbitrary; EFIE; trough guide; cylindrical; dipole; moment method; antenna; aperture coupled;

    Abstract : This thesis deals with the analysis of dipoles, patches, and aperture coupled patches located in an infinitely long cylindrical structure with arbitrary cross-section. The analysis exploits the two-dimensional nature of the structure by expanding all fields and currents in spatial harmonics along the cylinder axis, and solving the subsequent spectral two-dimensional problems by the moment method.

  4. 2. Treatment of coagulopathy in patients with critical COVID-19

    Author : Sandra Jonmarker; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Introduction: Thromboembolic complications affect a large proportion of patients with critical COVID-19, and it may be associated with an increased risk of death. It has been hypothesized that both the virus of SARS-CoV-2 itself and the inflammation caused by the infection puts patients in a pro-coagulative state. READ MORE

  5. 3. Strategic Life-Cycle Modeling and Simulation for Sustainable Product Innovation

    Author : Henrik Ny; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable product innovation; planning; strategy; backcasting; life-cycle assessment LCA ; strategic life-cycle management SLCM ; systems; modeling; simulation;

    Abstract : Many specific methods and tools have been developed to deal with sustainability problems. However, without a unifying theory it is unclear how these relate to each other and how they can be used strategically. A Framework for Strategic Sustainable Development (FSSD) is being developed to cover this need for clarity and structure. READ MORE
