  1. 16. PENSIERI - An Inquiry into Sketching and Modelling in Design

    Författare :Maral Babapour Chafi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Physical and Digital Modelling; Sketching; Design Activities; Concept Generation; Product Representations;

    Sammanfattning : When proposing ideas for design solutions, designers often make representations, for example sketches and models of different kinds. This thesis seeks to examine what designers do when interacting with different media to externalise their ideas, and the resources they have at their disposal. LÄS MER

  2. 17. Generation, Modulation, and Detection of Signals in Microwave Photonic Systems

    Författare :Andreas Wiberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microwave photonics; radio over fiber; mm-wave generation; PSK; QAM; subcarrier modulation; photonic frequency multiplication; spurious free dynamic range third-order intercept point; millimeter-wave photonics; uni-travelling-carrier photodiode; millimeter-wave communication system;

    Sammanfattning : This thesis deals with the use of photonic technology in microwave and millimeter-wave applications. The two major parts of this work have been techniques for transmission and signal generation. LÄS MER

  3. 18. A Stacked Prism Lens Concept for Next-Generation Hard X-Ray Telescopes

    Författare :Wujun Mi; Mats Danielsson; Peter Nillius; Ralf K. Heilmann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; focusing X-ray telescopes; Wolter-I optics; stacked prism lens; focused UV lithography; grayscale e-beam lithography; proximity effect correction; angular resolution; effective collecting area; röntgenteleskop; Wolter-I-optik; staplade prismalinser; fokuserad UV-litografi; elektronstråle-litografi; Fysik; Physics;

    Sammanfattning : Over the past half century, the focusing X-ray telescope has played a very prominent role in X-ray astronomy at the frontier of fundamental physics. The finer angular resolution and increased effective area have enabled more and more exciting discoveries and detailed studies of the high-energy universe, including the cosmic X-ray background (CXB) radiation, black holes in active galactic nuclei (AGN), galaxy clusters, supernova remnants, and so on.

  4. 19. Setting Limits in Nature and the Metabolism of Knowledge : The Case of the Critical Load Concept

    Författare :Johanna Alkan Olsson; Gunilla Öberg; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Föroreningsfrågor; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : In the 1980s, the earlier understanding that environmental problems are relatively simple was questioned. In order to handle the perceived complexity, several responses emerged. LÄS MER

  5. 20. How on Earth : Operationalizing the ecosystem service concept for local sustainability

    Författare :Katja Malmborg; Lisen Schultz; Albert Norström; Elin Enfors-Kautsky; Erik Gomez-Baggethun; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecosystem service bundles; System dynamics; Participatory methods; Usable knowledge; Leverage points; Learning; Complexity; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Ecosystem services are co-produced in social-ecological systems. Due to their social-ecological framing, ecosystem services hold the potential to be a concept around which different stakeholders with vested interests in different aspects of landscape management can meet. LÄS MER
